Abstract: Background Chronic kidney disease (CKD) is a major health issue for HIV-positive individuals, associated with increased morbidity and mortality. Development and implementation of a risk score model for CKD would allow comparison of the risks and benefits of adding potentially nephrotoxic antiretrovirals to a treatment regimen and would identify those at greatest risk of CKD. The aims of this study were to develop a simple, externally validated, and widely applicable long-term risk score model for CKD in HIV-positive individuals that can guide decision making in clinical practice. Methods and Findings A total of 17,954 HIV-positive individuals from the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) study with ≥3 estimated glomerular filtration rate (eGFR) values after 1 January 2004 were included. Baseline was defined as the first eGFR > 60 ml/min/1.73 m2 after 1 January 2004; individuals with exposure to tenofovir, atazanavir, atazanavir/ritonavir, lopinavir/ritonavir, other boosted protease inhibitors before baseline were excluded. CKD was defined as confirmed (>3 mo apart) eGFR ≤ 60 ml/min/1.73 m2. Poisson regression was used to develop a risk score, externally validated on two independent cohorts. In the D:A:D study, 641 individuals developed CKD during 103,185 person-years of follow-up (PYFU; incidence 6.2/1,000 PYFU, 95% CI 5.7–6.7; median follow-up 6.1 y, range 0.3–9.1 y). Older age, intravenous drug use, hepatitis C coinfection, lower baseline eGFR, female gender, lower CD4 count nadir, hypertension, diabetes, and cardiovascular disease (CVD) predicted CKD. The adjusted incidence rate ratios of these nine categorical variables were scaled and summed to create the risk score. The median risk score at baseline was −2 (interquartile range –4 to 2). There was a 1:393 chance of developing CKD in the next 5 y in the low risk group (risk score < 0, 33 events), rising to 1:47 and 1:6 in the medium (risk score 0–4, 103 events) and high risk groups (risk score ≥ 5, 505 events), respectively. Number needed to harm (NNTH) at 5 y when starting unboosted atazanavir or lopinavir/ritonavir among those with a low risk score was 1,702 (95% CI 1,166–3,367); NNTH was 202 (95% CI 159–278) and 21 (95% CI 19–23), respectively, for those with a medium and high risk score. NNTH was 739 (95% CI 506–1462), 88 (95% CI 69–121), and 9 (95% CI 8–10) for those with a low, medium, and high risk score, respectively, starting tenofovir, atazanavir/ritonavir, or another boosted protease inhibitor. The Royal Free Hospital Clinic Cohort included 2,548 individuals, of whom 94 individuals developed CKD (3.7%) during 18,376 PYFU (median follow-up 7.4 y, range 0.3–12.7 y). Of 2,013 individuals included from the SMART/ESPRIT control arms, 32 individuals developed CKD (1.6%) during 8,452 PYFU (median follow-up 4.1 y, range 0.6–8.1 y). External validation showed that the risk score predicted well in these cohorts. Limitations of this study included limited data on race and no information on proteinuria. Conclusions Both traditional and HIV-related risk factors were predictive of CKD. These factors were used to develop a risk score for CKD in HIV infection, externally validated, that has direct clinical relevance for patients and clinicians to weigh the benefits of certain antiretrovirals against the risk of CKD and to identify those at greatest risk of CKD., Editors’ Summary Background About 35 million people are currently infected with HIV, the virus that causes AIDS. HIV destroys CD4 lymphocytes and other immune system cells, leaving infected individuals susceptible to other infections. HIV infection can be controlled, but not cured, using combination antiretroviral therapy (cART), and, nowadays, the life expectancy of many HIV-positive individuals is similar to that of HIV-negative people. HIV-positive individuals nevertheless experience some illnesses more frequently than HIV-negative people do. For example, up to a third of HIV-positive individuals develop chronic kidney disease (CKD), which is associated with an increased risk of cardiovascular disease and death. Persons with CKD may have an impaired effect of the filtration units in the kidneys that remove waste products and excess water from the blood to make urine, thereby leading to a reduced blood filtration rate (the estimated glomerular filtration rate [eGFR]) and waste product accumulation in the blood. Symptoms of CKD, which rarely occur until the disease is advanced, include tiredness, swollen feet, and frequent urination. Advanced stages of CKD cannot be cured, but its progression can be slowed by, for example, controlling hypertension (high blood pressure) and diabetes (two CDK risk factors) and by adopting a healthy lifestyle. Why Was This Study Done? The burden of CKD may increase among HIV-positive individuals as they age, and clinicians need to know which individuals are at high risk of developing CKD when choosing cART regimens for their patients. In addition, clinicians need to be able to identify those HIV-positive individuals at greatest risk of CKD so that they can monitor them for early signs of kidney disease. Some antiretroviral drugs—for example, tenofovir and atazanavir/ritonavir (a boosted protease inhibitor)—are associated with kidney damage. Clinicians may need to weigh the benefits and risks of giving such potentially nephrotoxic drugs to individuals who already have a high CKD risk. Here, the researchers develop and validate a simple, widely applicable risk score (a risk prediction model) for CKD among HIV-positive individuals and investigate the relationship between CKD and potentially nephrotoxic antiretroviral drugs among individuals with different CKD risk score profiles. What Did the Researchers Do and Find? To develop their CKD risk score, the researchers used clinical and demographic data collected from 17,954 HIV-positive individuals enrolled in the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) study who had an eGFR > 60 ml/min/1.73 m2 and were not taking a potentially nephrotoxic antiretroviral at baseline. During 103,185 person-years of follow-up, 641 individuals developed CKD. Older age, intravenous drug use, hepatitis C coinfection, lower baseline eGFR, female gender, lower CD4 count nadir, hypertension, diabetes, and cardiovascular disease predicted CKD. The researchers included these nine factors in their risk score model (which is available online) and defined three risk groups: low (risk score < 0), medium (risk score 0–4), and high (risk score ≥ 5) risk of CKD development in the next five years. Specifically, there was a 1 in 393, 1 in 47, and 1 in 6 chance of developing CKD in the next five years in the low, medium, and high risk groups, respectively. Because some patients started to use potentially nephrotoxic antiretroviral drugs during follow-up, the researchers were able to use their risk score model to calculate how many patients would have to be treated with one of these drugs for an additional patient to develop CKD over five years in each risk group. This “number needed to harm” (NNTH) for patients starting treatment with tenofovir, atazanavir/ritonavir, or another boosted protease inhibitor was 739, 88, and 9 in the low, medium, and high risk groups, respectively. Finally, the researchers validated the accuracy of their risk score in two independent HIV study groups. What Do These Findings Mean? These findings provide a simple, validated risk score for CKD and indicate that the NNTH when starting potentially nephrotoxic antiretrovirals was low among HIV-positive individuals at the highest risk of CKD (i.e., treating just nine individuals with nephrotoxic antiretroviral drugs will likely lead to an additional case of CKD in five years). Although various aspects of the study, including the lack of data on race, limit the accuracy of these findings, these findings highlight the need for monitoring, screening, and chronic disease prevention to minimize the risk of HIV-positive individuals developing diabetes, hypertension, or cardiovascular disease, or becoming coinfected with hepatitis C, all of which contribute to the CKD risk score. Moreover, the development of a tool for estimating an individual’s five-year risk of developing CKD with or without the addition of potentially nephrotoxic antiretroviral drugs will enable clinicians and patients to weigh the benefits of certain antiretroviral drugs against the risk of CKD and make informed decisions about treatment options.

Abstract: Background Toll-like receptors (TLRs) are transmembrane receptors that activate cells of the innate immune systems upon recognition of pathogen-associated molecular patterns. The TLR4 is an essential component of the innate immune response to various microorganisms. We investigated the impact of TLR4 polymorphism on development of opportunistic diseases in HIV-infected patients. Methods The presence of TLR4 Asp299Gly single nucleotide polymorphisms (SNPs) was determined in a cohort of 180 antiretroviral treatment-naive HIV-1 infected patients and evaluated in relation to the occurrence of opportunistic infections. TLR4 genotyping was performed by real-time PCR. Results One hundred sixty-five patients were homozygous for the wild-type genotype (AA); 15 patients (8,3%) were heterozygous for the Asp299Gly SNP (AG). TLR4 polymorphism was associated with more frequent development of the opportunistic infections, such as active tuberculosis (OR=3.27; 95% CI [1.21–10.29]), herpes zoster (OR=4.15; 95% CI [1.24–7.29]) and toxoplasmosis (OR=6.23; 95% CI [1.19–18.67]) compared with genotype AA. In addition, TLR4 SNP was associated with development of opportunistic diseases among individuals with CD4 cell count of>100 cells/mm3, compared with homozygous HIV-infected patients (OR, 5.25; 95%, CI [2.28–10.47]). Conclusion This study suggests a greater risk of developing of active tuberculosis and other opportunistic infections in patients with the Asp299Gly TLR4 polymorphism., Background Diagnosis of acute HIV infection (AHI) is uncommon in resource limited settings. This abstract describes acute HIV infection in women in three East African countries. Methods Women at high risk of infection were recruited from ‘hot spots’ in Kericho (rural Kenya), Kampala (urban Uganda) and Mbeya (rural Tanzania). HIV negative eligible women were prospectively screened twice a week using HIV nucleic acid testing. A positive test led to entry into an intensive one-month diagnostic verification phase to definitively establish HIV infection status. Clinical and laboratory assessments were performed semiweekly. Supportive care and symptomatic treatment was provided. Results Overall, 1197 high-risk volunteers have enrolled to date with 37 cases of AHI identified (31 prior to detectable antibodies). Mean age at HIV acquisition was 24.4 years (range 18–34). Only six reported unprotected sex with a known HIV positive partner. Crude incidence was 2.77/100 PY (95% CI:±0.87). Of the 37 AHI cases; 14 presented with malaria-like symptoms (all smear negative), 7 flu-like symptoms while 16 had 1–2 mild complaints (8) or no symptoms (8). Overall, AHI cases were evaluated at 302 visits and at least one symptom was reported in only 75 visits (24.8%). Pregnancy did not increase the frequency of symptoms but dehydration due to vomiting resulted in 2 of the 3 hospitalizations observed. Conclusion Identification of AHI is feasible in East Africa. Young, rural, females are most vulnerable. Individuals with clinical syndromes suggestive of malaria, but excluded by microscopy, should raise index of suspicion for AHI. The majority of cases had few or no symptoms or brief non-specific symptoms not requiring medical intervention. Screening protocols based on malaria syndromic presentation would not identify the majority of AHI cases., Background The use of combination antiretroviral therapy (cART) has resulted in dramatic reductions in HIV-related mortality and morbidity. Nevertheless, despite sustained suppression of viral replication there remains evidence of increased levels of immune activation, particularly in patients initiating treatment during late-stage infection. We asked whether early initiation of therapy could potentially ameliorate this apparent limitation of cART. Methods 40 subjects identified as acutely or early HIV-1 infected were treated with either 3-drug cART (N=14) which included TDF/FTC, a ritonavir-boosted protease inhibitor (atazanavir or darunavir) or 5-drugs (N=26) cART as above with raltegravir and maraviroc. CD38 and HLA-DR expression on CD8+ T cells were determined by flow cytometry at baseline and weeks 48 and 96. Levels of sCD14 by ELISA were measured at weeks 48 and 96. These results were compared to values in 13 healthy, HIV-1 uninfected volunteers. Results A total of 29 subjects, 11 on 3-drugs and 18 on 5-drugs remained on therapy, suppressed and were available for analysis at 48 weeks. After 96-weeks 25 subjects, 9 on 3-drugs and 16 on 5-drugs were similarly analyzed. There are no statistically significant differences (Mann-Whitney, p, Background HIV controllers, maintaining low plasma HIV RNA levels (, Background HIV+ individuals in care with access to ART may experience a wider range of non-AIDS-related complications than previously.

Methods Individuals from a large prospective cohort collaboration (D:A:D) were followed starting from 1999 until death, loss-to-follow-up or February 2011, whichever came first. Underlying causes of death were attributed based on the Coding of causes of Death (CoDe) system. Results 3,802 deaths occurred in 49,734 individuals followed for 304,695 person-years (rate=12.5/1000 person-years [95% CI 12.1–12.9]). Leading underlying causes were: AIDS-related (29%), non-AIDS-defining malignancies (NADM; 14%), liver disease (LD; 13%), cardiovascular disease (CVD; 11%), invasive bacterial infection (7%), drug overdose (3%), accidents (2%), renal disease (1%) and unknown (7%). Decreases over time occurred in rates of all-cause (17.4/1000 person-years in 1999–2000 to 8.3 in 2009–2011), AIDS-related (5.9−1.9), LD (2.7−0.8) and CVD-related (1.8−0.8) mortality. However, the rate of NADM deaths remained stable (1.5−1.6). After accounting for factors including current CD4 count (Table), there was still evidence of decreases over time in LD and CVD deaths, but not AIDS-related. The proportion of all deaths attributed to AIDS (34% in 1999–2000 to 22% in 2009–2011), NADM (9%–20%) and LD (16%–9%) changed over time. Conclusion Underlying causes of death have changed markedly over the last 12 years. AIDS remains the leading cause. Although there have been marked reductions over time in AIDS-related deaths, this effect is removed when accounting for current CD4 and other factors. NADMs are now the leading non-AIDS cause. Rates of LD and CVD-related deaths have decreased substantially, even after accounting for the factors listed below, suggesting other improvements in patient management during the study period. No trends in emerging causes of unexpected deaths were observed. Collection of specific causes of deaths is important to allow earlier interventions in HIV case management., Background US CDC guidelines recommend at least annual HIV testing for those at high risk. Nonadherence to testing guidelines and late diagnosis of infection may contribute to HIV transmission. Methods HPTN 061 is a feasibility study of a multi-component HIV prevention intervention for at-risk black MSM in 6 US cities. At enrollment, participants were offered HIV testing. Participants reporting past HIV-uninfected or unknown status at enrollment and no HIV testing within the prior 12 months were considered nonadherent to HIV testing guidelines. Participants with newly diagnosed HIV and CD4, Background Recent data showing a high incidence of HIV infection among men who have sex with men (MSM) who had been tested during the past year suggest that MSM might benefit from more frequent HIV screening (e.g., every 3 to 6 months). We assessed the cost-effectiveness of HIV screening at 3 and 6 month intervals compared with annual screening. Methods We used a published mathematical model of HIV transmission to evaluate screening intervals for a cohort of 10,000 MSM ages 14–64. We incorporated HIV transmissions averted due to serostatus awareness for each screening interval (e.g. 3, 6, 12 months), as well as HIV testing costs and treatment costs for averted transmissions. We assumed an HIV incidence of 1.27% for MSM and conducted threshold analyses on incidence. We assumed conventional testing with a 3rd generation antibody test and 75% receipt of results. In sensitivity analyses, we investigated the impact of all rapid testing and 100% receipt of results. We valued each HIV transmission averted using lifetime treatment costs of $367,134. Results Compared to annual screening, conventional HIV testing every 3 months and 6 months averted 2.04 and 1.36 HIV transmissions, respectively, and both were cost-saving. The incremental cost-effectiveness of 3-month versus 6-month screening also was cost-saving. Threshold values for HIV incidence at which screening was cost-saving were 0.3% and 0.5% at the 3-month and 6-month screening intervals, respectively. Screening with a rapid test was cost-saving at both 3- and 6-month intervals compared to annual screening. The incremental cost-effectiveness of 3-month versus 6-month screening was $813 per QALY saved.

Conclusion HIV screening with either conventional or rapid testing as frequently as every 3 months is cost-saving or very cost-effective. Reexamination of HIV screening intervals for MSM should be considered on the basis of the economic evidence., Background Pooling techniques have been advanced to improve the cost effectiveness of nucleic acid testing for diagnosis of serologically undetectable acute HIV infections in resource limited settings. Previously reported methods have relied on serum samples. The goal of this study is to develop and apply a novel dried blood spot (DBS) based RT-PCR pooling technique to facilitate household sample collection, efficient diagnosis, and treatment-as-prevention strategies in Mochudi, Botswana. Methods Laboratory-prepared DBS samples with plasma viral load >50,000 copies/mL are diluted with HIV negative DBS samples to generate estimates of sensitivity for pool sizes of 5, 10, 25, 50, and 100 samples. RT-PCR is performed using the Abbott RealTime HIV-1 assay. This analysis will inform the development of an acute HIV case detection pooling algorithm to be applied to all seronegative samples collected as part of a large prevention study cohort.Table 1Sensitivities of DBS pooled RT-PCR Mean copies per mL (95% CI) Pool size % Sensitivity 38680.96 (28170.00, 49191.91)510019965.30 (15020.37, 24910.23)1094.18735.91 (6800.21, 10671.61)2571.44992.78 (3579.63, 6405.93)5070.63121.21 (1676, 4566.20)10027.8 Results Preliminary findings based on 9 HIV positive samples used to create 90 pools, reflected sensitivities ranging from 27.8% for pools at 1/100 dilution to 100% for 1/5. We were able to detect the presence of an HIV positive sample in pools of 10 with a sensitivity of 94.1%. The difference in sensitivity between pool sizes of 25 and 50 was minimal. Conclusion We have demonstrated the feasibility of using DBS pooling for acute HIV diagnosis. Because acute HIV infection involves high viral loads, we can reasonably expect to detect acute cases >50,000 copies/mL in pools of 10 with 94.1% sensitivity. Although increasing pool size decreases sensitivities, the false negative rate during the acute window period could be significantly reduced even with the use of larger pools. Because secondary HIV transmission in acute and recent HIV infection may contribute significantly to the epidemic in Botswana, the potential for a treatment-as-prevention strategy would be facilitated by screening methods to detect acute HIV cases., Background In Kenya, HIV-1 viral load (VL) monitoring is commonly performed with the COBAS Amplicor using plasma specimens, but interest is growing in transitioning to real-time PCR (RT-PCR), including the COBAS Ampliprep/COBAS Taqman (CAP/CTM), using dried blood spots (DBS). RT-PCR has several advantages including full automation, lower detection limit, and broader measuring range. Benefits with DBS include sample collection via finger or heel stick, low biohazard risk, and specimen transportation under ambient conditions. Prior to implementation, a direct evaluation of the two assays using DBS field specimens is required. Methods This analysis compares sensitivity, specificity, negative (NPV) and positive (PPV) predictive values, concordance correlation, and agreement, as evaluated with Bland Altman analyses, between HIV-1 VL measurements using paired plasma and DBS specimens obtained from 512 HIV-1 infected treatment-naive pregnant women enrolled in the Kisumu Breastfeeding Study, and tested with the COBAS Amplicor and CAP/CTM assays. Results The sensitivity and NPV of VL detection in DBS specimens were higher with CAP/CTM (sensitivity: 100%, 95% CI: 99.1–100.0; NPV: 100%, 95% CI: 59.0–100.0) than COBAS Amplicor (sensitivity: 96.6%, 95% CI: 94.3–98.1; NPV: 58.8%, 95% CI: 40.7–75.4), with comparable PPV; 99.5%, 95% CI: 98.3–99.9 and 99.6%, 95% CI: 98.6–100.0 for the respective assays. The specificity of VL detection in DBS specimens was lower with CAP/CTM (77.8%, 95% CI: 40.0–97.2) than COBAS Amplicor (95.2%, 95% CI: 76.2–99.9). Good concordance and agreement were observed when testing paired plasma and DBS specimens (Figures 1 and 2).Figure 1 Concordance correlation analyses of HIV-1 viral load quantification among plasma and DBS specimens collected from patients enrolled in Kisumu Breastfeeding Study and tested with COBAS Amplicor and CAP/CTM. COBAS Amplicor plasma viral loads were used as reference group for comparison: a)vs. COBAS Amplicor DBS viral loads; b) vs. CAP/CTM plasma viral loads; c) vs. CAP/CTM DBS viral loads [Correlation plots]. Figure 2 Bland-Altman analyses to evaluate agreement in HIV-1 viral load quantification among plasma and DBS specimens collected from patients enrolled in Kisumu Breastfeeding Study and tested with COBAS Amplicor and CAP/CTM. COBAS Amplicor plasma viral loads were used as reference group for comparison. The difference between the reference and the comparision assay/specimen type were plotted against the average of the reference group and the comparision assay/specimen type o; a)COBAS Amplicor DBS viral loads; b) CAP/CTM plasma viral loads; c) CAP/CTM DBS viral loads [Bland-Altman plots]. Conclusion There was good correlation between DBS and plasma viral loads as well as between COBAS Amplicor and CAP/CTM. However, CAP/CTM had a better sensitivity compared to COBAS Amplicor. Our findings show that DBS may be an alternative sample type to plasma for viral load measurement, which could increase access to viral load monitoring in resource limited settings.

The implications of not having routine VL testing are not known in this setting. Methods As part of a longitudinal adherence study, participants on first-line HAART in Bangalore, India were monitored every six months, for 24 months, with CD4 cell count, HIV VL, and genotype, if VL>1000copies/ml. Participants with virologic failure (VF) often continued on first line therapy due to local resource constraints. We compared the incidence of WHO-defined criteria for immunologic failure (IF) to VF, defined as two consecutive VL >1000 copies/ml or VL>10,000 copies/ml for those who had only one VL available. Results Five hundred nine participants were included in the study (63% male, median age 36, median duration on HAART at start of study 14 months). Forty (7.8%) experienced VF, 25 (6.1%) IF and 10 (2.0%) both VF and IF. The sensitivity of immunologic criteria to detect VF was 20%, specificity 95% and positive-predictive value 29%. Of the 40 participants with VF only, 18 developed new thymidine analogue mutations over the follow-up period during which they continued on first line therapy; 11 of 18 developed high- level NRTI resistance, which would preclude subsequent tenofovir use. In addition, six participants developed NNRTI mutations, which confer genotypic resistance to etravirine and rilpivirine. Conclusion WHO IF criteria have low sensitivity for detecting VF and presence of IF poorly predicts VF. Relying on CD4 count data alone would lead a substantial number of unnecessary switches to second-line therapy. A notable proportion of patients would be continued on first line therapy that they are already failing, jeopardizing future HAART options. Universal access to VL monitoring would avoid costly switches to second line therapy and preserve future therapeutic options., Background Rapid scale-up of antiretroviral therapy (ART) in Southern Africa has put enormous strain on health systems. Information about acquired drug resistance in treated individuals is important to monitor quality of programmes and to ensure that ART policies remain appropriate. The majority of resistance data so far have come from urban, hospital-based programmes; limited data have been reported from rural treatment programmes. Methods Adult (≥16 years) HIV-infected individuals with virological failure (2×VL>1000 copies/ml) on first-line NNRTI-based ART were enrolled from all 17 primary health care clinics of the Hlabisa ART Programme. Genotypic resistance testing was performed using the in-house SATuRN/Life Technologies system. Sequences were analysed and genotypic susceptibility scores (GSS) were calculated using RegaDB and Stanford HIVDB 6.0.5 algorithms. Results 187 adults enrolled between Dec 2010 and Dec 2011; median age 37 years (IQR 31–45); 70% female. Median time on ART 41 months (IQR 31–53); median time on failing regimen 30 months (IQR 20–42). 120 (64%) had never achieved full virological suppression (VL≤50 copies/ml). 160 (86%) individuals had ≥1 drug resistance mutation; 149 (80%) and 153 (82%) respectively had NRTI and NNRTI mutations. 72 (38%) had at least one thymidine analogue mutation (TAM) and 32 (17%) had ≥3 TAMs. 14 (7%) had other NRTI mutations that might impact on second-line therapy (K65R-12 (6%); Q151M-3 (2%)). The standard second-line regimen was substantially compromised (defined as GSS≤1.5) in 33 (18%) individuals. Conclusion There are high levels of acquired drug resistance associated with prolonged virological failure in this rural primary health care programme. Standard second-line regimens would be significantly compromised in almost one in five adults. This suggests a role for genotypic resistance testing in routine care but, more importantly, it highlights the need for increased attention to quality of care and adherence to virological monitoring guidelines., Background In assessing the cost-effectiveness of CD4 versus viral load (VL) monitoring strategies, the “resistance cost” associated with delays in identifying non-suppression must be considered, and would likely favor a VL strategy. Here we examined the extent of protease (PR) mutation accumulation according to duration of 2nd-line (2L) failure. Methods Since 2004, the Harvard PEPFAR/APIN Program has provided ART to over 85,000 people in Nigeria. Approximately 8% of patients have received protease inhibitor (PI)-based 2L therapy (mostly LPV/r). A subset of patients with VL failure, defined as 2 consecutive VLs >1000cpm after ≥6 months on 2L, underwent genotypic resistance testing. Accumulation of PR mutations according to time on failing regimen was determined. Results Of 6714 patients who received PI-based ART, 661 (9.8%) met virologic failure criteria. Genotypes were performed on 53 samples (median CD4 183; VL 30150 at 2L failure).

Patients on non-suppressive 2L therapy for ≤12 months prior to genotype testing had a median of 3 (IQR, 1–5) International AIDS Society (IAS) PR mutations, compared with 6 (IQR, 0–6.5) among patients failing for >24 months. Patients developed a median of 1.1 (IQR, 0–2.3) IAS PR mutations per 6 months on failing 2L therapy. In 30% of failing patients no PR mutations were present, suggesting non-adherence; when these patients were excluded, the median number of IAS PR mutations/6 months increased to 1.8 (IQR, 1.1–2.8). For patients failing >24 months, high- or intermediate-level resistance to LPV/r and ATV/r was present in 64%, with 9% to DRV/r.

Conclusion This is the first report assessing the impact of duration of non-suppressive 2L therapy on the accumulation of PR resistance in a resource-limited setting. This information provides insight into the “resistance cost” associated with failing to switch non-suppressive 2L regimens, and highlights the issue of 3rd-line access., Background In the USA, CD4 cell counts and HIV-1 viral load (VL) have been tested concomitantly 2–4 times/year for persons receiving antiretroviral therapy (ART). With the advancement of effective HIV care, many individuals now have viral suppression and higher CD4 cell counts. After therapy is initiated, the CD4 cell count is used to monitor the need for prophylaxis against opportunistic infections and immunologic response to ART. We assessed whether CD4 cell counts may be performed less frequently after viral suppression of, Background Cryptococcal meningitis (CM) is a leading cause of death in AIDS patients in sub-Saharan Africa. Cryptococcal antigen (CRAG) can be detected weeks before symptom onset, and those who are asymptomatic but CRAG+ have a high risk of subsequent CM and mortality. A new CRAG point-of-care immunochromatographic lateral flow assay (LFA) is available that is remarkably easy to administer without laboratory infrastructure or expertise and has excellent sensitivity and specificity. Methods We assessed the cost-benefit of targeted CRAG screening for patients with CD4, Background Penicillium marneffei is an emerging dimorphic mycosis endemic in South and Southeast Asia, and a leading cause of mortality among HIV-infected people in the region. Factors governing the seasonal incidence of P. marneffei infection have yet to be identified, and may yield critical insights into possible reservoirs or modes of transmission. We used P. marneffei incidence data from Ho Chi Minh City (HCMC), Vietnam from 2004–2010, as well as high-resolution weather data, to identify climactic factors that could account for the observed seasonality of P. marneffei infection. Methods This study included all P. marneffei, Cryptococcus neoformans, and HIV-related admissions to the Hospital for Tropical Disease (HTD) in HCMC from 2004–2010, as well as temperature, humidity, wind, and precipitation data for the corresponding period. We used logistic regression modeling to identify factors significantly associated with P. marneffei and C. neoformans admissions. We also estimated the P. marneffei incubation period by incorporating different exposure-to-admission delays in our models. Results This analysis included 719 HIV-infected patients presenting with penicilliosis. P. marneffei admissions were closely associated with humidity (P, Background RIF upregulates CYP 450 isoenzymes and can lower EFV exposure, particularly if weight ≥50 kg, However, clinical data have not shown reduced HIV virologic suppression with 600 mg EFV+RIF. We conducted a nested PK study to evaluate EFV concentrations and virologic suppression in A5221 patients on EFV(600 mg) and RIF-based TB treatment. Table 1 Weight (kg) 4) compared to Whites(22.9% vs 3.9%;p=0.002). Conclusion Overall, RIFcoadministration was not associated with lower EFV trough concentrations; patients weighing ≥50 or ≥60 kg had lower EFV Cmin, but there was no association with subtherapeutic Cmin nor virologic suppression. These data from a multinational, predominantly non-White population do not support guidelines for weight-based dosing of EFV with RIF., Background HIV is the strongest risk factor for progressing from latent M. tuberculosis infection to tuberculosis (TB). 9 months of daily self-administered INH (9H) is efficacious but has low completion rates and may cause hepatotoxicity. PREVENT TB demonstrated that 3 months of once-weekly rifapentine 900 mg+INH 900 mg under direct observation (3HP) was at least as effective as 9H, but only 3% of the participants were HIV+, so enrollment of HIV+ persons was extended to adequately assess tolerability. Methods HIV+ persons ≥2 years old who were either tuberculin skin test positive or close contacts of TB cases were randomized to 3HP or 9H. Persons could not receive antiretroviral therapy (ART) for 90 days after enrollment. Participants were enrolled from the U.S., Brazil, Spain, Peru, and Canada between June 2001 and December 2010. Follow-up for TB continues through 2013. Results Of 4,128 participants enrolled with known HIV status and who received ≥1 dose of study therapy, 393 were HIV +: 207 in the 3HP and 186 in the 9H arm. In the MITT analysis (enrolled participants who were eligible), 178/201 (89%) HIV+ persons completed 3HP vs. 125/193 (65%) on 9H (P< 0.001). The proportion of participants with a serious adverse event (SAE), ≥1 AE, or hepatotoxicity was lower in 3HP than 9H (4 vs. 11%; P=0.006; 22 vs. 40%; P=0.004; 2 vs. 6%; P=0.03). Compared to 1,888 HIV-negative participants treated with 3HP, HIV+ persons were less likely to permanently discontinue treatment for any reason (11 vs. 20%; P, Background HIV and TB are threats to pregnant women and infants. Treatment with rifampin can reduce ART concentrations and increase risk of treatment failure and vertical transmission. We describe the pharmacokinetics (PK) and pharmacodynamics of EFV among pregnant HIV-infected women. Methods Prospective cohort of HIV-infected pregnant women with and without TB in Soweto. Women taking ART with EFV 600 mg had PK sampling at 37 weeks’ gestation or at delivery and then six weeks post-partum. EFV concentrations were measured in cord blood at delivery and in infants at 7 days. Post-hoc Bayesian estimates of PK parameters from nonlinear mixed-effects modeling with allometric scaling are reported. Results Among 41 HIV-infected pregnant women taking EFV ART, 19 received rifampin (TB/HIV) and 22 ART alone. Median age and weight were 29 years and 70 kg. For 35 women with pre-/peripartum EFV PK, median (IQR) estimated EFV trough (Cmin) was 1.31 (0.84, 1.86)mg/L, apparent oral clearance (CL/F) 13.62 (10.67, 18.44)L/h, and volume of distribution (Vd/F) 516 (440, 591)L. 31% had Cmin20 copies/mL (one had TB/HIV). Median cord blood EFV concentration was 1.09 (0.46, 2.38)mg/L. EFV concentrations were BLQ in 6/24 cord blood and 25/30 infant 7-day samples; both correlated with maternal concentrations. 0/35 infants were HIV-infected at 6 weeks. In mothers 6 weeks postpartum, median EFV Cmin was 1.75mg/L, CL/F 10.79L/h, and Vd/F 433L; 30% had Cmin, Background TMC207 (bedaquiline) (B) is a diarylquinoline in Phase 2 development to treat drug-sensitive and drug-resistant tuberculosis. It is being evaluated in novel combination regimens with an aim to minimize adverse interactions with antiretroviral therapy (ART). This study investigated the effect of enzyme inducers rifapentine (P) or rifampicin (R) on TMC207 pharmacokinetics.Geometric LS Means of Bedaquiline Confidence IntervalsTreatment GroupParameterWith InducerAloneMean Ratio90% ConfidenceRifapentine Group 1Cmax 2077333962.2(53.4, 72.5)AUC(0–1) 276126453142.3(37.8, 48.5)Rifampicin Group 2Cmax 2240371860.2(52.0, 69.8)AUC(0–1) 253146120941.4(37.7, 45.4)Results Table. Methods This was a 2-period, single-sequence drug interaction study performed in 2 groups of healthy subjects. Period 1 examined the PK of B and its M2 metabolite after a single 400 mg dose of B. Period 2 examined the effects of repeated doses of either P or R on the PK of B and M2. Subjects took P 600 mg (Group 1) or R 600 mg (Group 2) q.d. for 22 days. A single 400 mg dose of B was administered on Study Day 10 of period 2 followed by PK sampling for 14 days. Results 32 subjects were enrolled and 29 completed; B, alone, and in combination with P or R, was generally well tolerated. P and R both reduced the Cmax and AUC of B greater than M2. Conclusion Both P and R reduce the Cmax and AUC of single doses of B by approximately 58%. Future regimens with B to treat TB should avoid the inclusion of P or R. The development of B with R sparing regimens is ongoing., Background PA-824 (Pa) and bedaquiline (B) (TMC) are novel compounds in phase 2 development with established Early Bactericidal Activity (EBA) over 14 days. The study presented is an EBA study that evaluated these drugs alone or in combination with each other and with moxifloxacin (M) and pyrazinamide (Z) to identify a regimen with the potential to shorten treatment of TB in patients without the use of rifamycins or other drugs that interact adversely with antiretroviral Therapy (ART). Methods 83 participants enrolled (26% F, 74% M, including 6 HIV+) as five cohorts of 15 TB patients, each who received daily dosages of B alone, B with Z, B with Pa, Pa with Z and Pa with M and Z. A cohort of 8 patients received daily standard TB treatment (isoniazid, rifampin, Z and ethambutol: HRZE) as a control for the EBA quantitative mycobacteriology. The primary efficacy endpoint was the rate of change in number of colony forming units (CFU) of Mycobacterium tuberculosis per ml of sputum incubated on agar plates from serial sputum collections over the period Day 0 to Day 14. Results All cohorts had decreases in logCFU counts/ml of sputum from Days 0 to 14 that ranged from 1.2–2.7 over 14 days. While Z potentiated the activity of both B and Pa and compared favorably with the HRZE standard regimen, the cohort with the combination Pa-M-Z had numerically the greatest effect on CFU reduction. Conclusion The combination regimen of Pa-M-Z has potent bactericidal activity over 14 days in patients with pulmonary TB and has the potential to treat both Drug Sensitive- and Drug Resistant-TB (contains no INH or rifampicin) without adverse clinical interactions with ART. This regimen has been taken into an 8 week trial to treat DS- and DR-TB in patients with and without HIV infection., Background The impact of HIV on MDR-TB treatment outcomes in sub-Saharan Africa remains unclear where extensive rollout of highly active antiretroviral therapy (HAART) has occurred. We therefore compared the time to initial culture conversion among patients with and without HIV infection in a setting of individualized, ambulatory MDR-TB care in Botswana. Methods We performed a prospective cohort study of MDR-TB patients receiving ambulatory care at two public clinics in Botswana. The time to culture conversion and proportion converting were compared by HIV status using Cox proportional hazard ratios (HRs). Results 40 HIV-infected and 30 HIV-uninfected patients with MDR-TB and follow up cultures were identified. The median CD4+T-lymphocyte count of those with HIV was 215 cells/mm3 (IQR 129–347), and 36 (90%) were on HAART. 85% of HIV-infected and 83% of HIV-uninfected achieved culture clearance. The median time to initial culture conversion was 78 days (IQR 42–186) for HIV-infected and 95 days (IQR 70–133)for HIV-uninfected individuals [log rank p=0.62; unadjusted HR=0.9 (95% CI: 0.5 to 1.5)]. Adjusting for age, gender, TB treatment history and number of active antitubercular drugs used did not change this result [adjusted HR=0.8 (95% CI: 0.4 to 1.4)]. Toxicity was frequent in all subjects: ototoxicity occurred in 53% and 70%, neuropathy in 40% and 10%, and nephropathy in 25% and 7% of HIV-infected and uninfected patients, respectively. Neuropathy (p=0.005) & nephropathy (p=0.044) were significantly associated with HIV infection. Conclusion We found no difference in the proportion or time to initial sputum culture conversion between an HIV-infected and non-infected cohort of MDR-TB patients in Botswana. These results suggest that microbiologic outcomes among those with HIV can be comparable to those without HIV in similar settings with access to individualized TB treatment and HAART., Background Tuberculosis, the leading cause of death among HIV patients, is difficult to diagnose with smear microscopy. Xpert MTB/RIF, a near point-of-care, fully automated, nucleic acid amplification test for TB and for the detection of rifampin resistance, has been endorsed by WHO. Xpert has increased sensitivity compared with smear microscopy; however its cost-effectiveness and affordability in resource limited settings is still controversial. Methods Between August and December 2011, Partners in Hope integrated Xpert MTB/RIF alongside fluorescence microscopy for TB evaluation.Attribute of LaboratoryMicroscope typeTechnician experience and expertiseLaboratory staff workloadQuality of AFB MicroscopyPartners in HopeFluoroscenceAdvancedUsually manageableGoodStandard Malawian AFB laboratoryConventionalUsually limitedUsually overburdenedUsually poorAttributes of study laboratory and standard lab. All HIV-TB suspects were evaluated with spot AFB smear, morning Xpert and another spot smear. Patients were classified as smear-positive, indeterminate (only one scanty smear) or smear-negative based on Malawi TB Guidelines. Smear and Xpert results were compared to determine the number of excess cases detected by Xpert. Cost per excess case detected was calculated. Results 436 clinical samples were tested using Xpert. 417 were sputum samples and 19 extrapulmonary samples. Of 64 samples which tested positive by Xpert, 61 were sputum samples and 3 extrapulmonary samples. Corresponding smear results were available for 58 sputum samples.

Conclusion Xpert MTB/RIF increased TB detection by 16%-65% compared to fluorescence microscopy in a well-equipped laboratory. The Xpert may perform differently in a less sophisticated laboratory. However, cost per case detected was high and not affordable in Malawi., Background Xpert® MTB/RIF is a new molecular diagnostic tool, developed to increase detection and shorten time to diagnosis of sputum-smear-negative (SSN) tuberculosis (TB). In April 2011, Médecins Sans Frontières (MSF) in collaboration with the Zimbabwean Ministry of Health and Child welfare implemented two Xpert® MTB/RIF systems in a rural district in Zimbabwe serving two hospitals and 26 decentralised primary care clinics. Methods From May to October 2011, parallel testing with both smear microscopy and Xpert® MTB/RIF was performed on specimens from all TB suspects. We used information abstracted from clinical and laboratory records to compare the number of laboratory-confirmed TB cases, number of TB notifications, and the time to diagnosis among HIV/TB co-infected patients with sputum-smear-negative TB during 6 months before and after Xpert® MTB/RIF implementation. Results A total of 1672 sputum specimens were processed, of which 184 (11.0%) were smear-positive. Mycobacterium tuberculosis was detected by Xpert® MTB/RIF in 116 (7.8%) of the 1488 remaining smear-negative specimens. Comparing the period after implementing Xpert® with the period before, the proportion of TB notifications that were smear positive (33% versus 27%), smear-negative (48% versus 49%), sputum not tested (11% versus 12%), and extra-pulmonary (8% versus 12%) was unchanged. The median time to TB treatment initiation among HIV/TB co-infected patients with sputum-smear-negative TB, decreased at decentralised sites (from 18.5 days to 7 days), but remained constant at the hospital level (5.5 days before and 6 days after). Conclusion Xpert® MTB/RIF increased the number of laboratory-confirmed TB cases in rural Zimbabwe, enabling further task shifting of TB management. In settings where access to chest X-Ray and trained doctors is lacking the impact on TB notifications may be greater. Time-to-initiation of TB treatment at the decentralized clinics was reduced, which has the potential to reduce morbidity in individuals and reduce the risk of TB transmission to others., Background Recently, WHO recommended that GeneXpert MTB/RIF be used as first line diagnostic to test for TB in HIV positive individuals. Most patients initiating ART lack the classical symptoms for TB resulting in missed diagnosis. The role of symptom screen in predicting a positive GeneXpert result among pre-ART patients was studied. Methods This was a nested cohort study within a GeneXpert impact evaluation trial in pre-ART patients. TB symptomatic and asymptomatic adults (>18 yrs) at an ART initiation clinic in Harare were recruited between October 2011 and February 2012. For each patient, two spot sputum samples were collected and induction with 6% hypertonic NaCl performed in those who could not expectorate. Sputum samples were tested with GeneXpert (Cepheid) Test. Participants were followed-up for 3months. Results 150 participants were recruited and 126 produced specimens and were tested for TB using GeneXpert. Median CD4 count was 165cells/ul (IQR 79–256). Fifty-four percent of the participants had a cough (68/126). Induction was carried out in 19 participants and of these, 47% (9/19) were coughers and 53% (10/19) non-coughers. TB was diagnosed in 10% of participants (13/126; 95% CI 4–16); with an additional 2 cases diagnosed on second GeneXpert test. Significant predictors of disease were cough of any duration (p=0.019), night sweats (p=0.03) and weight loss (p=0.04). Of those induced, 16% (3/19) had a positive GeneXpert result. Notably, induced samples accounted for 23% (3/13) of the TB cases detected. Three percent (2/58) of the non-coughers were GeneXpert positive. Seven participants (5%) with negative GeneXpert results were started on TB treatment based on clinical suspicion. Conclusion TB testing using GeneXpert in pre-ART patients, with sputum induction, should be carried out routinely regardless of patient TB symptom status. A two step screening test and Xpert testing algorithm is needed for scale-up of universal TB testing in pre-ART patients., Background PNU-100480 is a linezolid analog with superior bactericidal activity against Mycobacterium tuberculosis in the hollow fiber, whole blood and mouse models that is time-dependent and unaffected by resistance mutations for standard TB drugs. PNU-100480 neither induces nor inhibits CYP3A4. This study is its first in TB patients. Methods Sputum AFB smear positive South African patients (incl. HIV+ not requiring ART) were randomly assigned to PNU-100480 600 mg BID (N=25) or 1200 mg QD (N=25), or standard 4-drug therapy (HREZ, N=9) for the first 14 days of treatment. Sputum mycobacterial burden was monitored both as log CFU/ml and time to detection (TTP) in automated liquid culture system (MGIT). Results 20% of subjects were women; 7% were HIV+. All subjects completed assigned treatments. There were no treatment-related serious adverse events nor any permanent discontinuations or dose reductions due to laboratory abnormalities. There was no effect on the QT interval. At baseline, the mean log CFU/ml and TTP were 6.95 and 116 hrs, respectively. Changes in mycobacterial burden during treatment are shown below. Lines indicate estimates by mixed-effect model repeated measures (MMRM) analysis; shading indicates 90% CI. MMRM analysis revealed that the 90% CI after the full treatment period excluded zero for all 3 treatments and for both monitoring methods. Seven PNU-treated patients (14%) had transient, asymptomatic ALT elevations on day 14 to 2–3x ULN that subsequently returned promptly to normal; none met Hy's law criteria. Conclusion Treatment with PNU-100480 600 mg BID or 1200 mg QD reduced the mycobacterial burden in sputum during 14 days of treatment. Both treatments were safe and reasonably well tolerated. Further studies of PNU-100480 in tuberculosis are warranted. EBA., Background More than 80% of patients with multidrug-resistant tuberculosis (MDR-TB) in Tugela Ferry, South Africa are co-infected with HIV. Concomitant treatment for both diseases is recommended, but concern about severe and additive toxicities of MDR-TB therapy and ART has slowed acceptance of community-based treatment. Methods Confirmed MDR-TB patients were treated at home by an injection team and returned to the clinic monthly where they were screened for common adverse events (AEs). Severity was graded using the DAIDS toxicity table. Safety labs were drawn monthly and TSH was drawn every 3 months. We reviewed clinical and laboratory AEs for all patients between November 2008 and April 2011. We examined the incidence of each AE in 6-month time blocks and the within-patient trend of each AE over time. We compared those who received concomitant MDR-TB/ART treatment to those who received MDR-TB treatment alone. Results Of 91 MDR-TB patients, 55% were female; median age was 34 (IQR 29–41); and 84% were HIV co-infected. 74 patients (97% of HIV+) were receiving ART and median baseline CD4 cell count was 207 cells/mm3 (IQR: 89–411). Ninety-nine percent of patients reported at least one AE during treatment, but most were mild and did not require therapy modification. The most common AEs were peripheral neuropathy (73%), injection site pain (66%), and arthralgia (43%). The most common severe AEs (grade=3) were psychosis (10%) and hypothyroidism (29%). Patients receiving concurrent ART did not experience AEs more frequently than those on MDR-TB therapy alone. Patients were significantly less likely to report most AEs later in their treatment course (Figure 1).Figure 1 AEs by 6-month time blocks. Conclusion Home-based treatment of MDR-TB and HIV is associated with high rates of mild AEs which are not increased by concurrent ART and can be managed symptomatically without changing MDR-TB therapy or ART. Treatment can be safely administered in a home-based care setting., Background The effect of chronic hepatitis B (HBV) on HIV outcomes is relatively unknown in sub-Saharan Africa (SSA) where a high burden of HIV-HBV co-infection exists. Methods Clinical and immunologic outcomes in response to ART were compared longitudinally between HIV mono- (HIV+) and HIV-HBV co-infected (HIV&HBV+) adults enrolled between November 2004-December 2010 at 18 Management and Development for Health (MDH)-PEPFAR supported HIV clinics in Tanzania. Inclusion criteria were: tested ≥×1 for HbsAg (DIMA), age ≥15, no prior ART. Results The prevalence of HBV was 837/13,107 (6.4%).Compared to HIV+ patients, HIV&HBV+ patients were more likely to be male, older, have lower median CD4+ cell counts, and higher ALT's (p values 120IU/L [38/813 (4.7%) vs. 303/12,136 (2.5%); HR 1.76 (1.25, 2.49), p200IU/l [20/831 (2.4%) vs. 102/12,236 (0.8%); HR 2.74, (1.66, 4.05), p, Background Few studies have examined the natural history of chronic hepatitis C virus (HCV) infection among HIV-infected persons in the era of combination antiretroviral therapy (cART). Our objectives were to: 1) compare the incidence of hepatic decompensation between cART-treated HIV/HCV-coinfected and HCV-monoinfected patients, and 2) evaluate determinants of decompensation among coinfected patients on cART. Methods We performed a cohort study among 4,286 cART-treated HIV/HCV-coinfected and 6,639 HCV-monoinfected patients in the Veterans Aging Cohort Study Virtual Cohort (1997–2010). All patients had HCV viremia and were HCV treatment-naïve. Coinfected patients received cART for at least one year and had an HIV RNA result >500 copies/mL within 180 days prior to starting cART (to identify new cART initiators). Hepatic decompensation events (defined by diagnoses of ascites, spontaneous bacterial peritonitis, variceal hemorrhage, or hepatocellular carcinoma) and death were evaluated. Cox regression was used to determine the adjusted hazard ratio (aHR) of hepatic decompensation associated with cART-treated coinfection and evaluated baseline risk factors for decompensation (alcohol abuse, non-black race, diabetes mellitus, FIB-4 >3.25, hemoglobin3.25 (aHR=7.18 [5.12−10.07]), and baseline hemoglobin, Background HIV-1/HCV coinfected patients respond poorly to pegylated interferon(PEG-IFN) and weight-based ribavirin(WBR), with sustained virologic response(SVR) of 27% in genotype 1 HCV treatment-naïve subjects (ACTG 5178 results). Nitazoxanide(NTZ) plus PEG-IFN and WBR has demonstrated improved efficacy in HCV monoinfected subjects. We hypothesized that addition of NTZ to PEG-IFN/WBR would improve HCV virologic responses in HIV-1/HCV co-infected persons. Methods HIV-1/HCV genotype 1 co-infected subjects naïve to HCV treatment received 4-week lead-in of NTZ(1000 mg/day) followed by 48 weeks of NTZ, PEG-IFN alfa-2a(180 µg/week) and WBR(1000–1200 mg/day). SVR was defined as undetectable serum HCV RNA (, Background The objective of this study was to examine the immunogenicity of the HPV-6, -11, -16, -18 vaccine in HIV-infected young women. Methods This phase II, open-label, multi-center trial was conducted through the Adolescent Trials Network for HIV/AIDS Interventions. Participants were 16-23 year-old women behaviorally infected with HIV. Two groups were enrolled: Group A (ART naÿ or had not received HAART for at least six months prior to study entry) and Group B (had received HAART for at least 6 months, with two HIV-1 RNA plasma viral loads, Background HIV-infected women are disproportionately affected by human papillomavirus (HPV)-related anogenital disease. A5240 is a clinical trial of 319 HIV-infected women at US, Brazil and South Africa sites to determine immunogenicity and safety of the quadrivalent HPV vaccine. Methods Safety and serostatus of HPV types 6, 11, 16, and 18 were examined in 222 women. The vaccine was administered at 0, 8, 24 weeks in 3 strata based on screening CD4: >350 (A), 201-350 (B), ≤200 cells/mm3 (C). HPV serotyping was performed using competitive Luminex Immuno-Assay (HPV-4 cLIA). HPV type-specific seroconversion analysis was on participants seronegative for the given type at baseline. Seroconversion was defined by: ≥20, ≥16, ≥20, ≥24 mMU/mL for types 6, 11, 16, 18 respectively. Two-sided 95% CIs are provided. Results We report preliminary safety and week 28 seroconversion results from A and B. At baseline, median age was 37 years (range 19–45), 13% were white, 57% black, and 29% Hispanic. Median nadir CD4 was 262 cells/mm3, 41% had undetectable HIV-1 viral load, 13% from non-US sites. No safety issues were identified; none of the grade ≥3 AEs was thought to be vaccine-related.

Retrospective cohort studies suggest an additive benefit of isoniazid preventive therapy (IPT) in patients on ART, but there are no controlled data on the efficacy and safety of IPT for patients on ART. Methods Using a pragmatic randomized double-blind placebo-controlled study design, we evaluated the efficacy of IPT among HIV-infected participants established on ART or newly starting ART in Khayelitsha, South Africa. Participants were randomized to daily isoniazid or matching placebo for twelve months, and followed for up to four years. Tuberculosis was excluded at screening by sputum culture. Development of incident tuberculosis was the primary endpoint. Secondary endpoints included toxicities and deaths. Results 1,329 participants contributed 3227 person-years (PY) of follow-up in the modified intention to treat analysis; 662 on placebo and 667 on IPT, with comparable CD4+count and proportion starting ART. Overall there were 95 incident tuberculosis cases: 3.6 (95% CI 2.8–4.7) versus 2.3 (95% CI 1.6–3.1) per 100 PY in the placebo and IPT arms respectively (HR 0.63, 95% CI 0.41–0.94, p=0.026). Study drug was discontinued due to pre-specified toxicity in 2.5% in the placebo arm and 4.1% in the IPT arm (logrank p=0.13). The number of deaths was similar between arms (3.0% and 2.1 respectively, logrank p=0.29). Conclusion Under field conditions, twelve months of IPT reduced the incidence of TB without causing excess harm in HIV-infected individuals established on ART or newly starting ART. It is feasible to implement IPT in busy ART clinics in settings with high HIV/TB co-morbidity., Background With improved survival of HIV-infected children, neurocognition is an important area to address. We examined the effects of HIV infection on cognitive, neurological, and behavioral functioning on perinatally-infected children. Methods HIV-infected children (4–15yrs) were recruited from a tertiary-care center in India, along with age-gender-and-income-matched HIV-negative children. Assessment tools included (i) soft neurological signs: Physical and Neurological Examination for Soft Signs (PANESS); (ii) neurocognition: culturally-adapted Wechsler Preschool and Primary Scales of Intelligence (WPPSI), Wechsler Intelligence Scale for Children (WISC-III); (iii) adaptive behaviour: Vineland Adaptive Behaviour Scales (VABS). Results We studied 167 children, (82 HIV-infected, 85 HIV-uninfected) with 56% males and mean age 8.6 yrs. Total IQ scores were lower among HIV-infected children compared to HIV-uninfected children (74.9 12.9 versus 87.915.4, p20%, (IQ 77.112.8, p=0.03). Viral load and ART status has no effect on IQ scores. Multivariate regression revealed that HIV status, weight-for-age Z-score and hemoglobin were independent factors that affected IQ scores (adjusted r2=0.25, p=0.006). The presence of HIV infection independently decreased IQ scores by 9.22 units. PANESS scores were higher among HIV-infected children compared to uninfected children (HIV-positive: 7.5, [3, 13.3]; HIV-negative: 4, [1.5, 9.5], p=0.02) suggesting higher degree of subtle neurological abnormalities in this group. Adaptive behaviour scores were similar for both HIV-infected and uninfected children irrespective of age and sex. Conclusion HIV-infected children had lower IQ scores and higher prevalence of soft neurological signs compared to HIV-uninfected children, indicating that subtle neurocognitive impairment is an important feature of perinatally-acquired HIV infection, particularly those with poor nutritional status. We recommend routine neurocognitive assessment and suggest that early intervention with initiation of ART before the onset of severe immunosuppression may improve outcomes in these children., Background HIV infected patients receiving combination antiretroviral therapy are at higher risk of cardiovascular morbidity and have accelerated aging notably of cognitive functions. The link between cardiovascular risk factors and cognition has rarely been investigated in HIV-infected cohorts. In a large hospital-based cohort, we explored whether cardiovascular risk factors are associated with cognitive performances. Methods The ANRS-CO3 Aquitaine Cohort recruits patients through a hospital-based information system on HIV-1 infection in the Bordeaux University Hospital in the Aquitaine region, South Western France. Between 2007 and 2009, 403 patients participated in a sub-study and had a thorough assessment of several cognitive domains. Cognitive performances were analyzed using both the raw test scores and the presence of neurocognitive impairment (NCI), based on the most recent definition of HIV-associated neurocognitive disorders. Selected cardiovascular risk factors were type 2 diabetes, hypertension, hypercholesterolemia, smoking status and BMI. Covariance analyses were computed to investigate the association between cardiovascular risk factors and raw cognitive test scores, adjusting for potential confounders. Logistic regression with the same covariates was used to analyse NCI as dependent variable. Results Mean age was 47.3 years and 79% were male. The prevalence of cardiovascular risk factors ranged from 9.7% for diabetes to 49.6% for current smoking, and 37.7% of participants had NCI. Lower performances in all cognitive tests were related to older age and lower education. Among cardiovascular risk factors, diabetes was significantly associated with lower performances in all cognitive tests after adjusting for potential confounders. By contrast, no such consistent associations were noted for any other cardiovascular risk factors. Diabetes prevalence did not significantly differ by NCI status (p=0.44). Conclusion In this hospital-based cohort, diabetes, but not the other cardiovascular risk factors, is associated with lower performances in all assessed cognitive domains. The mechanisms underlying our findings remain to be clarified but could involve inflammation and microcirculation., Background Current literature indicates that infection with HIV contributes to an increased risk of acute stroke. The goal of this study is to compare clinical and epidemiological characteristics of stroke patients with and without HIV infection. Methods We performed a retrospective chart review of stroke patients who were admitted to the stroke unit between January of 2005 and June of 2011. We identified 43 patients with known HIV infection at the time of admission for acute stroke. 101 controls were randomly selected from non-HIV patients who had acute stroke within the same time period. Clinical and epidemiological characteristics of two groups were compared. Results Of 1679 admissions with acute stroke, 43 (2.6%) were in HIV-infected patients (32 males, 11 females) and 101 in non-HIV infected patients (45 males, 56 females). Mean age was 57.8 years and 72.6 years, respectively. All 144 patients had acute ischemic stroke confirmed by imaging. Significant difference was identified in age, race, blood pressure on admission, National Institute of Health Stroke Scale (NIHSS) on admission, and HDL level (Table 1). The presence of co-morbidities (HTN, DM, hyperlipidemia), body mass index (BMI), homocysteine level, LDL, and coagulation profiles were not statistically different between two groups. In the HIV+ group, 30 patients (83%) were taking HAART prior to stroke onset. CD4 count was available in 37 patients; 21 had CD4 >200 cells/mm3 and 16 had CD4< 200 cells/mm3 (mean CD4 count=329.7 cells/mm3).Table 1Results of Significant CharacteristicsCharacteristicHIV Positive Group(N = 43)HIV Negative Group (N = 101)P ValueAge-Mean (Range)57.8 (41–80)71.6 (34–99)0.001Male sex-no (%)32 (74.4%)45 (44.6%)0.007Race0.001Caucasian11 (45.8%)72 (72.7%)African American13 (54.2%)14 (14.1%)Asian0 (0%)13 (13.1%)NIHSS on admission5.399.090.03Systolic Blood Pressure on Admission142.18158.190.018HDL (mg/dl)40.7247.710.043 Conclusion HIV infection increases the risk of stroke in younger patients. They have lower blood pressure, HDL and NIH stroke scale on admission compared to HIV negative stroke patients. Prevalence of DM, HTN, hyperlipidemia and other metabolic factors were not significantly different in the two groups, although the relatively small sample size and retrospective nature of the study represent limiting factors., Background To further our understanding of anal lesions in relationship to HPV genotypes in HIV-infected men who have sex with men (MSM), we analyzed HPV genotype distribution in anal disease categories based on cytology and histology results. Knowledge of HPV genotype attribution can allow estimation of the preventable fraction of anal intraepithelial neoplasia (AIN) and may indicate disease misclassification. Methods 363 HIV-infected MSM underwent anal cytology and high-resolution anoscopy/biopsy at an anal cancer screening clinic. Anal disease categories were determined by combining histology and anal cytology results. We evaluated presence of HPV genotypes by Linear Array and estimated preventable fractions of anal lesions based on attribution to genotypes included in bivalent, quadrivalent, and nonavalent HPV vaccines. We explored classification of histology-cytology disease groups based on distribution of carcinogenic HPV genotypes using unsupervised hierarchical clustering. Results The proportion of carcinogenic HPV infections increased from 51.4% in MSM without AIN to 98.2% in those with AIN3. HPV16 was the most common HPV genotype overall (28.1%) and among MSM with AIN2/3 lesions (51.8%). The attribution fractions of AIN2/3 to genotypes included in HPV vaccines ranged from 56.4% (95% CI: 47.0–65.3) for the bivalent vaccine to 89.1% (95% CI: 81.9–93.7) for the nonavalent vaccine. (Table) In the exploratory clustering analysis, the disease group of normal histology/HSIL cytology and AIN1histology/HSIL cytology clustered with AIN2/AIN3 on histology based on the distribution of carcinogenic HPV types. (Figure).Figure 1 Unsupervised hierarchical clustering of AIN disease categories (various cytology-histology combinations) by distribution of carcinogenic HPV gentypes.

Conclusion A substantial fraction of high grade AIN can be prevented by prophylactic HPV vaccines. Both anal cytology and high resolution anoscopy followed by anal biopsy and histology have limited sensitivity for prevalent anal precancer. We demonstrate that combined histology-cytology disease categories can improve misclassification in cross-sectional studies. Our analytical framework can be useful to compare attribution of anal disease categories to HPV genotypes across various populations and to estimate the extent of disease misclassification., Background Maraviroc (MVC) is a CCR5 antagonist approved for the treatment of CCR5-tropic (R5) HIV-1. This study evaluated a once-daily (QD), dual-therapy regimen of MVC plus atazanavir/ritonavir (ATV/r) in treatment-naïve patients; 96-week outcomes are presented. Methods In this Phase 2b, randomized, open-label study, 121 R5 HIV-1-infected patients received either MVC 150 mg QD (n=60) or tenofovir/emtricitabine (TDF/FTC) 200/300 mg QD (n=61) with ATV/r 300/100 mg QD for 48 weeks, later extended to 96 weeks. The primary endpoint was the proportion of patients with HIV-1 RNA500 copies/mL at failure or study discontinuation; virologic analyses detected no resistance, change in tropism or loss of susceptibility relevant to treatment in either arm. At Week 48, there was a greater reduction in immune activation on CD4+ cells in patients receiving MVC versus TDF/FTC. Markers of bone formation were significantly different between arms at both 48 and 96 weeks. Conclusion Durable virologic activity of MVC 150 mg QD+ATV/r was demonstrated through 96 weeks, with no differences between the arms in the rates of virologic failure, no resistance or change in tropism seen, and with most of the treatment difference due to low-level transient viremia. Differences between the arms in immune activation and bone markers require further investigation., Background Cobicistat is a novel investigational pharmacoenhancer with no anti-HIV activity. Methods An international, randomized, double-blind, double-dummy, active controlled trial was conducted to evaluate the efficacy and safety of cobicistat vs ritonavir as pharmacoenhancers of atazanavir (ATV/co vs ATV/r group) in combination with tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) in treatment-naïve patients. Key eligibility criteria were HIV-1 RNA ≥5,000 copies/mL, estimated glomerular filtration rate by Cockcroft-Gault formula (eGFR) ≥70 mL/min. Primary endpoint was HIV-1 RNA 100,000 copies/mL, the response rates were similar (86 vs 86%). Two subjects in ATV/co and none in ATV/r group developed resistance mutations to study drugs; both were M184V/I. Similar percentages of subjects in both groups (ATV/co vs ATV/r) had serious adverse events (AEs) (11 vs 7%), discontinued study drug due to any AEs (7 vs 7%), or had bilirubin-related AEs (4 vs 3%). Median increases in total bilirubin at Week 48 in ATV/co and ATV/r group were 1.9 and 1.7 mg/dL. Median increases in serum creatinine were 0.13 and 0.09 mg/dL. Median increases in total cholesterol were 4 and 10 mg/dL; increases in triglycerides were 16 and 24 mg/dL. Plasma exposures of ATV (steady state mean Ctau [ng/mL]) were comparable (796.1 vs 853.4). Conclusion ATV/co was noninferior to ATV/r in combination with TDF/FTC at Week 48. Both regimens achieved high rates of virologic success.

FTC/RPV/TDF is a well-tolerated, once daily STR treatment option. This is the first study to evaluate the efficacy and safety of switching from boosted Protease Inhibitor (PI) based HAART to a simplified regimen of FTC/RPV/TDF STR.

Methods In this multicenter, double-dummy-blinded, Phase III, non-inferiority study, HIV-1 infected ART-naive adults with HIV-1 RNA ≥1000 c/mL and no evidence of viral resistance were randomized 1:1 to receive DTG 50 mg QD or RAL 400 mg BID, in addition to investigator-selected backbone NRTIs of either TDF/FTC or ABC/3TC. Subjects were stratified by screening HIV-1 RNA (≤ and >100,000 c/mL) and backbone NRTI selection. The primary endpoint was proportion of subjects with HIV-1 RNA100,000 c/mL, 41% ABC/3TC. Proportion of subjects meeting the primary endpoint was 88% for DTG and 85% for RAL; difference (2.5%; 95% CI: −2.2% to 7.1%) met 10% non-inferiority criteria. For subjects with HIV-1 RNA >100,000 c/mL, response rate was 82% for DTG vs 75% for RAL. Secondary analyses supported non-inferiority: HIV-1 RNA, Background AZT/3TC/NVP and TDF/3TC/NVP BID have been recommended 1st-line ART regimens in Rwanda. TDF/3TC/NVP is the least well studied of the WHO-recommended 1st-line regimens. We compared the efficacy of this regimen with AZT/3TC/NVP. Methods Between 2009 and 2011, we enrolled ART-naive patients. CD4 counts (cells/ul) and viral load (VL) were collected before ART and at 26 and 52 weeks. The primary endpoint was a VL 1000 copies/ml. Results 1,072 HIV+ ART-naive patients were enrolled: 521 (48.6%) received AZT/3TC/NVP (AZT), 551 (51.4%) received TDF/3TC/NVP (TDF). Median age was 37; 64% were women. Median baseline CD4 count was similar 260, VL was >100,000 copies/ml in 43% (AZT) vs. 32% (TDF) (p< 0.001). The AZT versus TDF, 5.4% vs. 3.8% transferred to others health facilities, 3.6% vs. 4.0% were lost to follow-up, and 1.9% vs. 2.7% died. 10%(AZT) vs 4%(TDF) of discontinued therapy due to adverse effects (p=0.001). The primary endpoint were: 80% (441/551) TDF and 78% (410/521) receiving AZT attained a VL < 200 copies/ml by week 52. The median CD4 count increase was 88 in the AZT and 50 in the TDF groups (p=0.034). However, in patients with baseline VL >100,000 copies/ml, 44% (133/351) in the TDF vs. 56% (170/351) in the AZT group attained the primary endpoint (p= 0.001). 11.8% (TDF) and 7.7% (AZT) underwent GRT. 58% had >=1 NNRTI-resistance mutation: most commonly Y181C (34%) and K103N (16%). 53% had >=1 NRTI-resistance mutation: most commonly M184V (48%) and K65R (29%). K65R emerged exclusively in the TDF group. Conclusion TDF/3TC/NVP was as effective as AZT/3TC/NVP at attaining, Background In the ECHO and THRIVE studies (HIV-1 treatment-naive patients), rilpivirine (RPV) 25mg qd and efavirenz (EFV) 600mg qd plus background N(t)RTIs resulted in a 78% response rate (viral load [VL], Background In 2009, South Africa's National AIDS Council recommended TDF access to HIV+ adults and ABC to HIV+ infants/children. We analyzed the effects of these guideline changes on NRTI-resistance mutations in ART virological failure (VF) and analyzed the effect of the cumulative second-line LPV/r use on emerging PI resistance. Methods HIV RT and PR sequences were obtained from plasma samples submitted for genotypic resistance testing to the Tygerberg National Health Service Laboratory between 2006 and 2011 from patients experiencing ART VF. Demographic and ART treatment data were obtained from the physicians submitting samples. Results Between 2006 and 2011, 1,525 plasma samples were obtained from 1,293 patients, of whom 57% were female and 42% =1 of the following major PI-resistance mutations: V32I, M46I, I47A, I50V, I54V, L76V, V82A/F, I84V, and L90M. 17 (4%) of 42 LPV/r recipients had major DRV/r resistance mutations (V32I, I50V, and L76V). Conclusion The increased use of TDF and ABC since 2009 has been associated with a markedly increased frequency of TDF-resistance (K65R) and ABC-resistance (L74V). Compared with TDF/3TC/EFV recipients, the risk of developing K65R was higher in patients with TDF/3TC/NVP VF (88% vs 31%; p=0.002) and lower in patients with TDF/3TC/LPV/r VF (7% vs 31%; p=0.008). Among 439 LPV/r recipients, 42 (10%) had LPV/r resistance and 17(4%) DRV/r cross-resistance., Background Since the availability of viral load (VL) assay with a threshold of 20 copies/mL, some patients display VL values between 20 and 50 copies/mL. The aims of our study were to: (i) identify factors associated with low level viremia (LLV) in patients receiving stable suppressive antiretroviral therapy (cART); and (ii) assess virological outcome during the year following LLV detection. Methods Retrospective study among the 4820 patients followed in our institution fulfilling the inclusion criteria: (i) stable cART for at least 6 months; (ii) all VL 50 copies/mL)/(number of VL determinations) before study inclusion. Results Among the 656 patients included, 5.8% were in group LLV+. The nature of the ongoing cART did not differ between LLV- and LLV+ groups. In the multivariate analysis, only CDC clinical stage B/C at study inclusion (OR=2.9; 95% CI=1.4–5.9; P=0.003) and a higher “Blip Ratio” before study inclusion (OR=0.9; 95% CI=0.9–1.0; P=0.001) were independently associated with LLV. During the follow-up, the proportion of patients experiencing virological failure (2 consecutive VL >50 copies/mL) was not different between LLV- and LLV+ groups (4% vs 8%, respectively; P=0.32); and 40% of patients shifted from LLV+ to LLV- status. Conclusion LLV was infrequent in our series and the one-year follow-up did not evidence a higher rate of virological failure than in patients always fully-suppressed. LLV seems to be a transient phenomenon that might be driven by residual ongoing viral replication and/or viral release and/or accuracy of VL assay in lower values., Background Alternatives to EFV for the treatment of HIV-infection in patients with TB are warranted. Rifampin decreases RAL exposure in healthy volunteers. We estimated the safety and efficacy of two doses of RAL and EFV in HIV-1-infected adults receiving rifampin for TB. Methods Multicentre, open-label, randomized, phase II trial. Antiretroviral naïve HIV-1-infected adults were randomized to receive RAL (400 or 800 mg bid) or EFV (600 mg qd), in combination with TDF and 3TC, after starting rifampin. The primary efficacy end-point was the proportion of patients with plasma HIV-RNA level50cp/ml was the main reason for failure and occurred in 6, 11 and 16 patients in RAL800, RAL400 and EFV, respectively. There was a trend towards more RAL, 3TC, and TDF resistance in the RAL400 than RAL800 arm. Safety of the three regimens was good with only 1, 1 and 3 grade 3/4 ALT elevations in RAL800, RAL400 and EFV arms, respectively. Conclusion At week 24, RAL800 mg bid provided the highest success rate in HIV-1-infected patients receiving a rifampin-based therapy for TB and should be considered for further evaluation., Background A5202 was a randomized equivalence study of four daily regimens of efavirenz (EFV) or atazanavir/ritonavir (ATV/r) with double-blinded tenofovir and emtricitabine or abacavir and lamivudine. Previous findings from A5202 reported women assigned ATV/r had higher-risk of virologic failure (VF) than women assigned EFV; also, women on ATV/r had higher risk of VF than men on ATV/r. This analysis relates ATV clearance (CL) to treatment efficacy and safety. Methods The associations between ATV CL and times to VF and safety event (first increased grade 3/4 sign, symptom, or laboratory abnormality), while on ATV/r (as-treated), were estimated with hazard ratios (HR) from Cox proportional hazards models, adjusted for screening HIV-1 RNA (105 copies/mL) and NRTIs. Additionally adjusted models included race-ethnicity (RE), age, baseline CD4 count, and body mass index. Interactions between ATV CL and sex, RE, and NRTIs were evaluated. A 1-compartment pharmacokinetic (PK) model including 815 subjects (88% of 928 randomized to ATV/r) was used to estimate subject-specific ATV CL. Atazanavir CL was categorized by overall sample tertiles (slow:¯9 L/hr). Analyses were restricted to 768 subjects of white, black, or Hispanic RE. Results Atazanavir CL association with time to VF differed significantly by sex (p=0.003, Table 1). The association between ATV CL and time to VF did not differ significantly by NRTIs (p=0.6) or RE (p=0.085); additionally adjusted model results were similar. There was no significant association between ATV CL and time to safety event (rapid vs. intermediate: HR 1.06; 95% confidence interval (0.79, 1.43); slow vs. intermediate: HR 1.28 (0.95, 1.72), p=0.22), nor a significant interaction with sex, NRTIs or RE for this outcome (p≥0.31). ATV Clearance Association with time to VF N=768: 131 females (28 VFs), 655 males (78 VFs) Comparison Hazard Ratio (95% Confidence Interval) Rapid (n=38) vs. Intermediate (n=29) among Female3.49 (1.24–9.84)Slow (n=64) vs. Intermediate among Female0.82 (0.26–2.54)Rapid (n=249) vs. Intermediate (n=210) among Male1.50 (0.82–2.71)Slow (n=196) vs. Intermediate among Male2.10 (1.16–3.77)*ATV CL by Sex Interation: p=0.003. Conclusion The differential in CL association with time to VF by sex may reflect PK/pharmacodynamic reasons for failure, and will require further investigations., Background Nevirapine (NVP) is metabolized by cytochrome P450 (CYP) 2B6. We investigated associations between single nucleotide polymorphisms (SNPs), haplotypes, and pharmacokinetics (PK) following SD NVP to prevent mother-to-child transmission (MTCT). Methods Protocol A5207 evaluated strategies to prevent NVP resistance following intrapartum SD NVP. At onset of labor, participants received SD NVP (200 mg) and were randomized to lamivudine/zidovudine, emtricitabine/tenofovir, or lopinavir/ritonavir (LPV/r), for 7 or 21 days. Plasma for NVP assay was obtained at post-partum day 1 and week 1, 3 and 5. Derived PK parameters included the NVP elimination constant estimated using linear mixed effect models based on natural logarithm of NVP measured between day 1 and week 3. We assayed 214 SNPs in ABCB1, CYP2B6, CYP2C19, CYP3A4, CYP3A5 and NR1I2. CYP2B6 metabolizer status was based on *6/*18 haplotypes. SNP and CYP2B6 haplotype associations were based on parametric regression models adjusted for body mass index and treatment arm as indicated. Results In A5207, 422 women in Haiti, India, Malawi, South Africa, Tanzania, and Uganda received SD NVP at onset of labor. This analysis includes 304 women (217 and 87 of African and Indian descent, respectively) with suitable NVP assay and genotype data. Among individuals of African descent, CYP2B6 metabolizer status was associated with slower NVP elimination (p =0.045), but not with week 5 NVP BLQ (below limit of quantification). Median elimination constants were −0.0105 (*6/*6 6/*18 or *18/*18*), −0.0108 (*6/− or *18/−), and −0.0113 (−/−) h−1. Among these individuals on LPV/r, an ABCB1 SNP (rs7787082) was associated with slower NVP elimination (p=0.0046). Among Indians, an NR1I2 SNP (rs2472682) was associated with increased likelihood of week 5 NVP BLQ (p=0.0061). Conclusion Slow metabolizer CYP2B6 genotypes were associated with slower elimination following SD NVP. This association appeared less pronounced than that described at steady state, suggesting effects on gene inducibility. Non-CYP2B6 SNP associations may be spurious., Background Prior studies investigating pharmacogenomics and efavirenz exposure use single plasma drug levels, which are limited by marked day-to-day variability. The Women's Interagency HIV Study (WIHS) performed 24 hour pharmacokinetics (PK) studies in a large number of HIV-infected women on efavirenz and calculated areas-under-the-curve (AUC) as measures of short-term exposure; concentrations in hair assessed long-term exposure. We typed 183 single nucleotide polymorphisms (SNPs) in 9 candidate genes known to influence efavirenz absorption, distribution, metabolism and elimination (ADME) and examined them in relation to AUC and hair levels in multivariate models. Methods Intensive PK studies were conducted in 111 women (74% African American; 17% Hispanic; 9% white). SNPs (n=183) with a minor allele frequency of >0.05 were analyzed in CYP2B6, CYP2C19, CYP3A4/A5, ABCB1, ABCC2, CYP2D6, SCL22A6, UDP, and UGT1A, along with other factors that could influence PK (race, age, menstrual status, diet, liver and renal function, weight). Hair efavirenz levels were measured in 84 women. Variables were examined with log-transformed EFV AUC and hair levels via linear regression; multivariable models were constructed by forward stepwise selection, including non-genetic predictors with p-values< 0.05 and genetic predictors with p-values< 0.001. Results Non-genetic factors, such as transaminase levels and orange juice consumption, were associated with EFV AUCs, but the most significant predictors associated with exposure were CYP2B6 516G>T, CYP2B6 983T>C and a p-glycoprotein transporter (ABCB1) haplotype (Table). CYP2B6 516TT (12.6% prevalence) was associated with 3.5-fold (95% CI 2.7–4.5, p=8.6x10−19) increases in AUC and 3.2-fold (2.1–4.7, p=1.3x10−11) increases in hair concentrations.Genetic and non-genetic factors associated with short-term EFV exposure (AUC, n=111) FactorEffect on AUC (±95% CI)p-valueDistribution of factorOranges or orange juice in preceding 5 days1.26 (1.05–1.50) 0.0119 76 (68.5%)For every doubling of ALT level1.23 (1.11–1.36) 0.0001 Median ALT (range) 23 (8–117) IU/LCYP2B6 983 T > C (rs28399499) 2.2×10 −10 0 doses of minor allele (TT)1.0095 (85.6%)–0 dose 1 or 2 doses of minor allele (TC/CC)1.96 (1.54–2.5)16(14.4%)–1 doseCYP2B6 516 G > T (rs3745274) 1.4×10 −18 0 or 1 dose of minor allele (GG, GT)1.0097 (87.4%)–0/1 dose 2 doses of minor allele (TT) 3.5 (2.7–4.5) 14(12.6%)–2 dosesABCB1 hdplotype (2SNPs:rs7779562 &rs4148745) 0.0004 0 doses of the haplotype1.0014 (12.6%)–0 dose 1 or 2 doses of the haplotype1.60 (1.24–2.1)97 (87.4%)–1/2 doses Factors associated with long-term exposure (hair levels, n = 84) -models include adherence Factor Effect on hair (±95% CI) p-value Distribution of factor ALT, Orange juice, ABCB1 haplotype, and adherence (below) not significantly associated with hair levelsCYP2B6 983 T > C ( rs28399499)0.021 0 doses of minor allele (TT)1.0074 (88.1%) –0 dose 1 or 2 doses of minor allele (TC/CC)1.70 (1.09–2.7)10 (11.9%)–1/2 dosesCYP2B6 516 G > T (rs3745274)1.0×10−10 0 or 1 dose of minor allele (GG, GT)1.0071 (84.5%) –0/1 dose2 doses of minor allele (TT) 3.2 (2.1–4.7) 13 (15.5%)–2 dosesSelf-reported adherence ≤74%1.004 (4.8%)75–94%0.94 (0.45–1.96)0.8813 (15.4%)≥95%1.10 (0.56–2.2)0.7767 (79.8%)Hair EFV PG table. Conclusion A comprehensive search for SNPs in genes associated with efavirenz ADME demonstrated that CYP2B6 516TT was associated with >3-fold increases in short-term (AUC) and long-term (hair) EFV exposure. The effect of this SNP on exposure over the prolonged duration represented by hair levels is reported for the first time. Genetic testing may allow optimization of EFV dosing., Background The pharmacokinetics of raltegravir in HIV-1 infected subjects is characterized by high inter/intra-patient variability. We investigated the potential contribution of the drug pharmaceutical formulation on raltegravir pharmacokinetics. Methods We firstly compared in vivo the pharmacokinetics of raltegravir from 50 patients given the drug by swallowing with those obtained from 10 HIV-infected patients that chewed raltegravir due to swallowing difficulties. Subsequently we evaluated in vitro the dissolution of raltegravir tablets under different conditions (pH 1, pH 6.8 buffer and water). Dissolution tests were performed comparing raltegravir whole tablets with tablets crushed by grinding in mortar and pestle. Results In the in vivo study we found that the raltegravir pharmacokinetic profiles in patients given the drug by swallowing were highly variable, characterized in some cases by multiple peaks and irregular/limited absorption. Conversely, patients given raltegravir by chewing presented regular pharmacokinetic profiles, characterized by single sharp drug peak and higher raltegravir absorption compared with patients given the drug by swallowing (Figure 1).Figure 1 Raltegravir time-concentration profiles in HIV-patients given the drug by swalling or chewing. The in vitro studies showed that the whole tablets presented relatively slow release profiles due to lacking disintegration. Crushed tablets tested in water and pH 6.8 buffer exhibited prompt and complete dissolution of raltegravir. For whole tablets tested in the acidic medium the raltegravir concentrations were very low, reaching less the 10% of the dose after 2h, owing to well-known poor solubility of raltegravir at low pH. However, when crushed tablets were tested in acid the profiles presented significantly higher concentrations of raltegravir (Figure 2)Figure 2 In vitro dissolution profiles of whole tabletes versus crushed tablets of raltegravir at different pH. . Conclusion HIV-infected patients given raltegravir by chewing showed higher drug absorption compared with patients given the drug by swallowing. This may be depends to problems related to the tablets disintegration leading to erratic drug release. The improvement of the raltegravir pharmaceutical formulation could reduce variability of raltegravir pharmacokinetics, eventually contributing to increase the response of HIV-infected patients., Background To inform optimal timing of ART initiation, we analyzed clinical outcomes during follow-up of HPTN 052 incorporating both AIDS and non-AIDS events related to HIV and ART. 052 WTS LB-K-M and table. Methods HIV+ adults (CD4+350 550/µL) from Africa, Asia, and South America were randomized to ART immediately or after CD4+, Background Nigeria's population of over 150 million and HIV prevalence of 3.8% ranks it among the top 5 countries with the highest HIV burden. Since 2004, HRSA has provided PEPFAR support to Harvard/APIN to develop a HIV prevention, care and treatment program at 32 hospitals in Nigeria. Methods ART eligibility in the adult program is consistent with the Nigerian and WHO ART guidelines. Enrolled patients that gave written informed consent with greater than 6 months of ART were included in this study. Patients had clinical exams and laboratory tests, at baseline, month 3, 6, and every 6 months thereafter. All patient data was collected and stored electronically. Treatment failure was defined as 2 consecutive viral loads > 1000 copies/mL following 6 months on ART. Results As of December 2010, 76,269 adult patients were enrolled on ART, 60,600 (79.5%) of which were ARV-naïve at baseline. Nine tertiary hospitals accounted for the majority of patients (53,406; 88.4%) with the remainder at 23 secondary. Female patients were more common (64.3%) and younger compared to men (median age 32 versus 39 years). Median baseline CD4 was 143 cells/mm3 and VL was 68,731 copies/mL. First-line ART for treatment-naïve patients included zidovudine (AZT) (51.6%), tenofovir (TDF) (35.3%) or stavudine (d4T) (7.5%) plus lamivudine/emtricitabine (3TC/FTC) plus an NNRTI - nevirapine (NVP) (68.4%)/efavirenz (EFV) (26%). The cumulative virologic failure rate for naïve patients was 21.4%, with the majority of failures occurring in the first year (56.9%). Applying the revised 2010 WHO recommendation defining virologic failure at > 5000 copies/mL, the cumulative failure rate was 13.6%, with 55.8% of failures in the first year. Virologic failure by time on ART. Conclusion Virologic failure rates were highest in the first year of ART and decreased with duration of ART. Particular emphasis on drug adherence and retention in care during the first year of ART may optimize patient outcomes., Background The second-line ART was rolled out in India in 2009 at 10 centers. Patients meeting immunologic/clinical failure criteria were evaluated by an expert panel and underwent viral load testing. Those found to have a confirmed virologic failure (VL> 5,000c/mL) were started on second-line ART (zidovudine/tenofovir/lamivudine/ lopinavir/ritonavir). We evaluated 18-month outcomes of patients started on second-line treatment. Methods Patients seen monthly and CD4 was performed every 6 months. VL testing was conducted 6 months after second-line ART initiation. We performed multivariable logistic regression modeling to determine factors associated with 6-month virologic suppression (, Background A large proportion of individuals enter health care very late in the course of their HIV-infection, these individuals have a poor clinical prognosis. This analysis aims to investigate trends in the percentage of individuals presenting late for care and identify factors associated with late presentation. Methods Individuals enrolled in the Collaboration of Observational HIV Epidemiological Research Europe (COHERE), which includes 33 cohorts from across Europe, who presented for care for the first time after 1st January 2000 were included. Late presentation was defined, as a person presenting for care with a CD4 count, Background Lipoprotein Lipase (LPL) is a key enzyme in lipid metabolism, especially for plasma circulating triglycerides (TG). Genetic variants of LPL have been associated to lipid levels in healthy individuals, cardiovascular disease, obesity and diabetes. Our aim was to evaluate the influence of three polymorphisms: Hind III (intron 8), Pvu II (intron 6) and S447X (exon 9) in plasma TG levels in HIV-1 infected children under HAART. Methods 52 children (28 girls and 24 boys) diagnosed with HIV-1 between 2005 and 2009, were retrospectively selected with at least one plasma TG level assessment. Also, 86 seronegative blood donors were randomly selected to estimate allelic frequencies in Argentinean population. TG levels were examined before and after one-year of HAART. Hypertriglyceridemia was defined as TG>150 mg/dL. Hind III (H+/H−), Pvu II (P+/P−) and S447X (S/X) were determined by PCR-RFLP. Wilcoxon sum rank test was used to compare median plasma TG among groups. Results Allelic frequencies for HIV-1 infected children were: H-,0.21 P-, 0.53 and X: 0.05, with no significant difference to controls. After one year of HAART, median TG levels were significantly lower in P+/P− (144 mg/dL) and P−/P− (95 mg/dL) compared to P+/P+ (180 mg/dL) (p=0.03 and p= 0.0002, respectively). A gene dose-dependent effect was observed for P- allele, and its presence was associated with a 7-fold lower risk of hypertriglyceridemia. Additionally, when H-is accompanying P-, the risk diminished to 15-fold (p=0.008, OR=0.06, 95% CI=, Background There are limited data on the pharmacokinetics (PK) of tenofovir (TFV) administered to pregnant women during labor or to newborns. Methods HPTN 057 is a phase I trial of tenofovir disoproxil fumarate (TDF) in HIV-infected pregnant women and their neonates in Malawi and Brazil. In the current cohort, women received 600 mg TDF at labor onset or 4 hours prior to C section (C/S) and newborns received 6 mg/kg TDF suspension daily ×7 doses. Plasma samples were obtained from mothers at delivery, from cord blood and from infants before and 2, 10 and 24 hours after the 1st, 4th and 7th doses. TFV concentration (conc) was determined by HPLC/MS/MS; lower limit of quantitation was 5 ng/mL. The PK target was to keep infant TFV conc >50 ng/ml (mean trough conc in nonpregnant adults) for the first week of life. Data are presented as median (range) or geometric mean (%CV). Results 33 mother-infant pairs were studied (21 vaginal deliveries, 12 C/S). Delivery occurred median of 4.5 (0.6–11.4) hours after dosing. Mean maternal TFV conc at delivery was 108 (76.1%) ng/mL. Mean cord blood TFV conc was 61 (69.3%) ng/mL. Cord blood TFV conc was>50 ng/mL in 24/31 (77%). Mean ratio of cord blood to maternal delivery TFV conc was 0.55 (64.0%). Infant 24 hr postdose conc was>50 ng/mL in 28/31 (90.3%) after the first dose, in 27/28 (96.4%) after the 4th dose and in 22/30 (73.3%) after the 7th dose. All infant TFV conc were >30 ng/mL. All mothers and infants tolerated TDF well. Mean (CV%) infant PK parameters are presented below: Dose Cmax(ng/mL) C24h(ng/mL) AUC(ng*hr/mL) t½ (hrs) 1288 (49.9%)104 (47.9%)3939 (37.6%)13.2 (80.1%)4336 (40.5%)112 (52.1%)4413 (37.4%)14.5 (45.0%)7221 (66.1%)69.7 (45.7%)3060 (49.0%)14.6 (96.1%)Mean (CV%) infant PK parameters. Conclusion This regimen provides TFV exposure similar to adults receiving 300 mg daily doses and is appropriate for use in neonates in studies of TDF used for HIV prophylaxis or treatment., Background P1093, is an ongoing, Phase 1/2 open-label PK, safety dose finding study of DTG plus optimized background regimen (children 6 wks to, Background Pharmacokinetics, safety and antiviral activity of fosamprenavir (FPV)/ritonavir (RTV) twice daily were evaluated in protease inhibitor (PI)-naive and -experienced HIV-1-infected children aged 6 months to48 weeks.

Conclusion The efficacy, safety and resistance profiles of etravirine 5.2 mg/kg bid plus OBR in this difficult-to-treat, antiretroviral-experienced pediatric population were comparable to those observed in treatment-experienced adults (DUET trials). Responses were better in children than adolescents, most likely due to less advanced disease, better adherence and less previous NNRTI use., Background New antiretrovirals are needed for HIV+ children. IMPAACT P1066 is a Phase I/II open label multicenter trial to evaluate pharmacokinetics (PK), safety, tolerability, and efficacy of multiple RAL formulations in treatment experienced HIV+ youth. RAL was given with an optimized background regimen. Dose selection was based upon intensive PK and safety data: 400 mg BID of RAL film-coated tablet (6–18 years) and weight-based dosing (~6mg/kg BID) of RAL chewable tablet (2 to, Background In Kenya, an estimated 7,000-10,000 children are HIV infected yearly. National targets for 10% of all HIV clinic patients registered being pediatric are often difficult to reach or fall behind adult uptake. In addition, concerns exist regarding retention of children in HIV/AIDS clinics. Such challenges are often magnified in rural settings due to frequent changes in caregivers,distances away from pediatric clinics, and extremes in poverty. Methods In 2004, HIV/AIDS care and treatment programs began developing under the President's Emergency Plan for AIDS Relief (PEPFAR) program in the SRV Province of Kenya, a largely rural population. Effort has been made to decentralize care, making more clinics closer to rural populations available. In addition, initiatives such as the “Mwangalizi” (“care givers”, often HIV positive adults linked with children to assure they come to HIV clinics) project have been implemented, and pediatric HIV support groups have been established. We describe aggregate program level data for the development of/uptake in HIV pediatric clinics. Results Between 2004 and 2011, 17,572 children received HIV testing through both voluntary counseling and testing (VCT) and diagnostic testing and counseling (DTC) initiatives. 5,310 children (mean age 10.0 +/− 3.3 years, 50.6% female) were enrolled in 57 pediatric HIV clinics. Of those enrolled, 44.3% started first line ART, 2.5% switched to 2nd line ART, and 1 has advanced to 3rd line ART. In 2005, 7.0% of HIV clinic attendees were children on ART, which increased to 10.5% in 2011 (p, Background Lipid abnormality is a common long-term complication in HIV-infected children. This study aimed to compare lipid profiles in children randomized to immediate versus deferred nevirapine-based antiretroviral therapy (ART). Methods This was a substudy of PREDICT (NCT00234091), a 144-week randomized trial of immediate ART (at CD4 15–24%) versus deferred ART (at CD4200 mg/dl, Triglyceride > 130 mg/dl, LDL>130 mg/dl, HDL≤40 mg/dl. Conclusion After 3 years, children randomized to immediate nevirapine-based ART had less dyslipidemia and lower TC/HDL ratio than the deferred ART group. This supports earlier nevirapine-based initiation to achieve favorable lipid profile in children with mild to moderate HIV-associated immune deficiency., Background Metabolic abnormalities, common among perinatally HIV-infected children (HIV+), may be caused by mitochondrial dysfunction that is induced by antiretroviral therapy (ARV) or chronic viral infection. We compared mitochondrial function [oxidative phosphorylation (OXPHOS) enzyme activities and lactate levels] of HIV+ and HIV-exposed, uninfected (HEU) children and, among HIV+, determined associations with fasting glucose, insulin, and homeostatic model assessment of insulin-resistance (HOMA-IR). Methods HIV+ and HEU were enrolled from the PHACS Adolescent Master Protocol. Children with known, non-HIV-associated mitochondrial disorders were excluded. Demographic and BMI [all] and CD4, HIV viral load, ARV exposures, and fasting insulin/glucose [HIV+ only] were collected. Main outcomes included venous and point-of-care (POC) lactate, venous pyruvate, and PBMC NADH dehydrogenase (CI) and cytochrome c oxidase (CIV) enzyme activities. A Wilcoxon test was used to compare outcomes between HIV+ and HEU; Spearman correlations were determined between insulin/glucose and OXPHOS activity in HIV+. Results 112 HIV+ and 66 HEU children were enrolled as of December 2011. HIV+ were older than HEU (15.8yr vs 12.4yr) with similar gender and racial distributions. BMI-Z was lower in HIV+ (0.41SD vs 0.54SD). Among HIV+, 45% were CDC stage B/C and 74% had CD4 >500 cell/mm3 with 60% having viral load, Background Peripheral neuropathy is a well-recognised and common condition in HIV-infected adults and may be related to use of antiretroviral therapy (ART) as well as be directly caused by HIV infection. Data on the prevalence, manifestations and risk factors of neuropathy in children are limited. Only few tools are available for clinical screening for peripheral neuropathy in children. We used the neuropathy symptom score (NSS) and neuropathy disability score (NDS) to screen for peripheral neuropathy in a cohort of children on ART. Methods In this cross-sectional study we included 182 children aged 5-15 years attending to healthcare facilities for ART collection in rural Mopani District, South Africa. Subjective and objective assessment of neuropathy was done using the NSS respectively NDS. These scores are feasible for resource-poor and skills-limited settings and only require a reflex hammer, cotton butt, tooth pick, and cold water. A definite diagnosis of peripheral neuropathy was defined by NSS≥3 or NDS≥ 2. Results Neuropathy screening was completed for 174/182 (96%) of children as 8 children did not fully cooperate. Median age was 9 years old and time on ART 2.0 years (2 months-6.4 years) with 86% on a stavudine-containing regimen. Symptoms related to neuropathy were reported by 49 children (27%) while NDS was positive for 25 children (14%). Forty-one (24%) of children fulfilled the criteria of peripheral neuropathy. Co-trimoxazole use was negatively associated with neuropathy presentation (OR 0.42, 95% CI 0.20–0.88; p=0.019) while there were tendencies for peripheral neuropathy to be associated with older age (p=0.09) and longer time on ART (p=0.06). Conclusion Peripheral neuropathy is a common condition in children collecting ART at healthcare facilities in rural Mopani District. The NSS and NDS can be used to screen for this condition in resource-poor settings., Background Antiretroviral (ARV) administration to HIV positive pregnant women and neonates reduces perinatal HIV transmission to less than 2% worldwide. However, concerns have been raised about potential toxicity in some neonates following gestational ARV exposure. Precise quantification of ARV exposure by history is difficult. Quantitative meconium analysis may better reflect fetal exposure during the third and perhaps second trimesters than history alone. Therefore, we developed and validated the first liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay for ARVs and metabolites in meconium. Methods Blank meconium (0.25g) was fortified with 16 ARVs and 4 metabolites, chosen based on prevalence of use by HIV-infected mothers in the SMARTT (Surveillance Monitoring of ART Toxicities) Study of PHACS. Samples were homogenized in methanol and subjected to solid phase extraction prior to quantification by LC-MS/MS. Tenofovir (TDF), lamivudine (3TC), emtricitabine (FTC), abacavir (ABC) and its carboxylate (CABC) and glucuronide (GABC) metabolites, nevirapine (NVP), raltegravir (RAL), saquinavir (SQV), amprenavir (AMP), darunavir (DRV), atazanavir (ATV), ritonavir (RTV), lopinavir (LPV), nelfinavir (NFV) and its bioactive hydroxyl (M8) metabolite were quantified with positive ionization; stavudine (d4T), efavirenz (EFV), zidovudine (AZT) and its glucuronide (GAZT) metabolite were quantified with negative ionization. Results Chromatographic separation was achieved with gradient elution; two injections were required due to the need for both positive (35 min) and negative (18 min) ionization modes. Extraction efficiencies were greater than 60% for all analytes except GABC (30%), and TDF, 3TC, GAZT and CABC (50%). Linear calibration curves employing 1/x2 weighting ranged from 10–2500ng/g (TDF, FTC, ABC, GABC, NVP, RAL, SQV, ATV, RTV, LPV, NFV, and M8), 50–2500ng/g (3TC), 75–2500ng/g (CABC), 100–25,000ng/g (AMP, DRV, AZT, EFV) and 500–25,000ng/g (d4T, and GAZT). Conclusion We developed a selective and sensitive LC-MS/MS method to detect antiretroviral medications and metabolites in meconium, which may be useful in quantifying the in utero ARV exposure for children of HIV-infected women., Background Mechanisms for increased cardiovascular risk in HIV-infected adults are incompletely understood, but heighted inflammation leading to a pro-thrombotic state has been proposed as a major contributor. In vitro platelet aggregation has been studied as a robust biological marker of coronary events and mortality. Methods We studied platelet aggregation in 25 HIV-infected subjects on ART with undetectable plasma HIV-1 RNA, median CD4 537 cells/mm3 (73.9%men) and 29 healthy HIV seronegative controls (44.4%men) in response to submaximal adenosine diphosphate (ADP, 0.4uM), arachidonic acid (AA, 0.15mM), or without agonist (spontaneous platelet aggregation [SPA]). The effects of one week of aspirin 81mg daily on activation markers, as measured by flow cytometry, and platelet aggregation were investigated. Two-tailed paired t tests and non-parametric Mann-Whitney U test tests were used for statistical analyses, with results given as medians with interquatile ranges. Results Compared to controls, HIV subjects on ART had increased platelet aggregation in response to ADP (10.8% [6.5, 42.3] vs 7.6% [3.3, 10.2], p=0.02), AA (54.9% [8.7, 89.9] vs 11% [2.5, 77.6], p, Background Limited data exist regarding the relationship between dysfunctional HDL (dys-HDL) and the osteoprotegerin (OPG)/receptor activator of the NF-kB ligand (RANKL) in HIV infection. Oxidized HDL (dys-HDL) has been shown to activate the NF-kB pathway in vitro. In view of this observation and the important role of biomarkers of activation of the NF-kB pathway (RANKL/OPG axis) in systemic inflammatory conditions, we used a novel assay that measures oxidation of HDL to explore possible associations between dys-HDL with RANKL/OPG and parameters that may predict these biomarkers. Methods We used cryopreserved serum samples from a prospective study (A5078) where subjects were enrolled as risk factor-matched triads of HIV-infected subjects (n=55) and HIV-uninfected individuals (n=36). Relationships between HIV infection, RANKL, OPG, RANKL/OPG, and dys-HDL were assessed using Wilcoxon tests and mixed effects linear regression analysis. The baseline covariates considered in the analysis are shown in Table 1 and also included fasting glucose and lipids, insulin, use of statins, anthropometric parameters of obesity, years of protease inhibitors (PI) use, and nadir CD4+ T cells. Significant (p, Background The association of inflammatory biomarkers with clinical events after ART initiation is unclear. Methods A5202 randomized 1857 treatment-naive subjects to abacavir/lamivudine or tenofovir DF/emtricitabine with efavirenz or atazanavir/ritonavir. Substudy A5224s measured inflammatory biomarkers on all substudy subjects with available plasma from baseline and weeks 24 or 96. The association of hsCRP, IL-6, sTNF-RI, sTNF-RII, TNF-a, sVCAM-1, and sICAM-1 with times to AIDS and non-AIDS defining events was analyzed with Cox proportional hazards models, with adjustment by ART assignment, and HIV-1 RNA or CD4. Time-updated analyses used the most current value. Results Analysis included 244 subjects; 85% male, 48% white non-Hispanic, with median age 39 years, HIV-1 RNA 4.6 log10 copies/mL, and CD4 240 cells/µL. A total of 13 AIDS-defining events (9 opportunistic infections; 3 AIDS-cancers, 1 recurrent bacterial pneumonia) and 18 non-AIDS defining events (6 diabetes, 4 cancers, 3 cardiovascular, 5 pneumonias) occurred. Higher baseline IL-6, sTNF-RI, sTNF-RII, and sICAM-1 were significantly associated with increased risk of AIDS-defining events. Adjustment for baseline HIV-1 RNA did not change results, while adjusting for CD4 count left sTNF-RI and sICAM-1 significantly associated with increased AIDS-defining events risk. Time-updated values of these biomarkers were also associated with increased risk of AIDS-defining events, even after adjusting for ART assignment, baseline and changes in CD4 and HIV-1 RNA. For non-AIDS events, only baseline hsCRP was significantly associated with increased risk; after adjustment for baseline CD4 count, IL-6 became significantly associated with higher risk. Analyses of time-updated biomarker value showed TNF-a to be significantly associated with increased risk of non-AIDS-defining events, even after adjustment for ART, baseline and changes in CD4 and HIV-1 RNA.Table 1Baseline and Time-Updated Biomarker Association with AIDS-Defining Events Unadjusted Baseline CD4, NRTI and NNRTI/PI Adjusted Time-Updated CD4, NRTI and NNRTI/PI Adjusted Biomarker HR (95% CI) p-value HR (95% CI) p-value HR (95% CI) p-value Baseline hsCRP (per 1 log, ug/ml higher)1.21 (0.80, 1.83)0.361.26 (0.84, 1.88)0.26Time-updated hsCRP (per 1 log, ug/ml higher)1.17 (0.78, 1.77)0.441.17 (0.78, 1.75)0.441.18 (0.78, 1.76)0.43Baseline IL-6 (per l log, pg/ml higher)1.98 (1.06, 3.69)0.0321.79 (0.96, 3.34)0.066Time-updated IL-6 (per 1 log, pg/ml higher)2.06 (1.12, 3.77)0.0201.88 (1.02, 3.47)0.0421.92 (1.04, 3.55)0.037Baseline sICAM-1 (per 1 log, ng/ml higher)8.28 (1 93, 35.59)0.0046.13 (1.51, 24.78)0.011Time-updated sICAM-1 (per 1 log, ng/ml higher)4.45 (1.18, 16.68)0.0273.66 (1.03, 13.08)0.0463.55 (0.98, 13.56)0.053Baseline sTNF-RI (per 1 log, pg/ml higher)10.24 (2.08, 50.32)0.0046.25 (1.17, 33.36)0.032Time-updated sTNF Rl (per 1 log, pg/ml higher)18.14 (2.94, 112.01)0.00211.58 (1.81, 73.92)0.01012.83 (1.99, 82.59)0.007Baseline sTNF-RII (per 1 log, pg/ml higher)3.45 (1.28, 9.33)0.0152.89 (0.99, 8.46)0.052Time-updated sTNF-RII (per 1 log, pg/ml higher)3.51 (1.27, 9.67)0.0152.98 (1.03, 8.60)0.0443.03 (1.04, 8.79)0.041Baseline sVCAM 1 (per 1 log, ng/ml higher)2.29 (0.59, 8.92)0.231.92 (0.47, 7.75)0.36Time-updated sVCAM 1 (per 1 log, ng/ml higher)1.77 (0.41, 7.64)0.4515.9 (0.36, 6.98)0.541.47 (0.34, 6.43)0.51Baseline TNF-a (per 1 log, pg/ml higher)2.28 (0.67, 7.78)0.192.17 (0.61,7.79)0.23Time-updated TNF-a (per 1 log, pg/ml higher)1.94 (0.54, 6.98)0.311.78 (0.47, 6.74)0.401.76 (0.47, 6.62)0.40Biomarker Association with AIDS-Defining Events.

We examined the efficacy, cost, and relapse rate combinations that would make ‘cure’ cost-effective compared with antiretroviral therapy (ART). Methods We used a Monte Carlo simulation of HIV disease (CEPAC model) to assess the impact of suppressive ART either continued indefinitely, or followed by one of three hypothetical strategies for HIV eradication: gene therapy (GeneRx), chemotherapy to activate the latent viral reservoir (Chemo), and an allogeneic bone marrow transplant (BMT). Patients eligible for inclusion in the model were virologically suppressed on first-line ART for one year. Patients who relapsed after a cure strategy restarted on ART. For each strategy we examined combination rates of cure, upfront cost, and monthly relapse rates to determine benchmarks for which the eradication strategies would compare favorably to ART.

Abstract: Background: Hydroxyurea (HU) is an immunomodulatory agent that has been documented to enhance the antiretroviral activity of nucleoside reverse transcriptase inhibitors, such as abacavir (ABC) and didanosine (ddI), and would be expected to improve virologic efficacy. Methods: A 48-week, phase IV, multicenter, open-label, proof-of-concept clinical trial was conducted to evaluate second-line, protease inhibitor (PI)-sparing therapy with ABC/efavirenz (EFV)/ddl plus HU or without HU in HIV-infected subjects failing to achieve HIV-1 RNA â‰¤ 400 copies/mL after â‰¥ 16 weeks of treatment with lamivudine /zidovudine or lamivudine/stavudine, plus 1 or 2 Pls. Subjects were assigned to ABC (300 mg twice daily)/ EFV (600 mg once daily)/ ddI (400 mg once daily) plus HU (500 mg twice daily) (n = 30) or this regimen without HU (n = 24). Results: Baseline mean HIV-1 RNA was 3.86 log10 copies/mL and CD4+ cell count was 345 cells/mm3. A similar percentage of subjects in the non-HU arm (58%) and HU arm (53%) completed the study. Intent-to-treat: missing = failure analysis showed no differences in proportions of subjects in the non-HU and HU arms achieving undetectable plasma HIV-1 RNA levels at week 24 (

Abstract: Objectives: To examine trends in acquired immunodeficiency syndrome (AIDS) risk behavior and human immunodeficiency virus (HIV) seroprevalence among injecting drug users (IDUs) in New York City from 1984 through 1992.Design and Setting: Comparisons were made between two surveys of IDUs at the same hospital-based New York City drug abuse detoxification program: 141 IDUs in 1984 and 974 IDUs in 1990 through 1992. National Death Registry, New York City Health Department, and drug treatment program records were also used.Participants: Persons attending detoxification program randomly selected for participation. Eligibility was based on injection within previous 2 months; 99% acceptance rates were obtained. Participants in the 1984 and 1990 through 1992 surveys were 66% and 79% men, 21% and 19% white, 33% and 34% African American, and 45% and 46% Latin American, respectively.Interventions: Community-based AIDS prevention programs, including underground syringe exchanges.Main Outcome Measures: Acquired immunodeficiency syndrome risk behaviors; HIV serostatus; CD4+ cell counts; death rates among 1984 subjects; and injection and intranasal routes of drug administration.Results: The HIV seroprevalence remained stable at slightly more than 50%. Mean CD4+ cell counts declined from 0.716 x 10(9)/L (716/microL) to 0.575 x 10(9)/L (P < .009). Annual death rate among 1984 subjects was 3%, with a significantly higher rate among HIV-seropositive subjects (relative risk, 2.57; 95% exact binomial confidence interval, 1.12 to 6.61). Large-scale declines were observed in AIDS risk behaviors, eg, use of potentially contaminated syringes declined from 51% to 7% of injections (P < .001). Recent additional risk reduction was associated with use of the underground syringe exchanges. Intranasal heroin use was the primary route of drug administration for 46% of heroin admissions to New York City drug treatment programs.Conclusions: The HIV seroprevalence has remained stable among this population of New York City IDUs for almost a decade. Continuation of current trends should lead to further reduction in HIV transmission, although reversal of the trend to intranasal use could lead to substantially increased transmission.

11. Prevalence of anemia and correlation with biomarkers and specific antiretroviral regimens in 9690 human immunodeficiency virus-infected patients: findings of the Anemia Prevalence Study.

Author: Mildvan D, Creagh T, Leitz G, and Anemia Prevalence Study Group
Abstract: OBJECTIVE: To describe anemia prevalence and correlates with biomarkers and antiretroviral therapy (ART) in HIV/AIDS. METHODS: Multicenter, cross-sectional study; clinical laboratory data collected at single visits, including hemoglobin (Hb), CD4+ count, HIV-1 RNA. Patients receiving care at US physician offices during the year 2000. Main outcome measure was anemia (Hb < 14 g/dL [men]; < 12 g/dL [women]) and marked anemia (Hb < 11 g/dL [men]; < 10 g/dL [women]) prevalence. Multivariable models examined association of anemia prevalence with HIV-1 biomarkers and ART. RESULTS: Among 9690 patients, prevalence of anemia and marked anemia was 36% and 5%, respectively. Among 1721 patients receiving no ART, 39.7% were anemic; among 7252 receiving highly active antiretroviral therapy (HAART), 35.5% were anemic (p = 0.001). Anemia was most prevalent among men (37.3 vs. 32.3%; p = 0.0008), blacks (49 vs. 26% [whites]; p < 0.0001), patients with CD4+ < 200 cells/mm(3) (57 vs. 23% [> or = 500 CD4+]; p < 0.00001), and HIV-1 RNA > 30 000 copies/ml (53 vs. 30% [< 500 copies/ml]; p < 0.00001). Marked anemia was more common in women (6.8 vs. 4.3%; p < 0.0001). Among treated patients, logistic regression analysis controlling for CD4+, HIV-1 RNA, sex, and ethnicity, zidovudine (ZDV)-containing regimens (except combination with saquinavir/ZDV/lamivudine) were associated with increased overall anemia risk (odds ratio, 1.39 : 1.74). No regimen was associated with increased risk for marked anemia. Multivariable logistic regression showed CD4+, sex, and ethnicity more strongly associated with anemia than any ART regimen. CONCLUSION: This large, single-visit, cross-sectional, US-based study shows that anemia remains highly prevalent in HIV-infected patients. Data from this analysis suggest low CD4+ count, black ethnicity, and male sex are consistently strongest correlates of overall anemia; women are significantly more likely to have marked anemia.

Abstract: Strategies to limit life-long dependence on antiretroviral therapy (ART) are needed. We randomized 81 human immunodeficiency virus (HIV)-infected subjects to 4 interventional arms involving continued ART plus ALVAC vCP1452 (or placebo) with or without interleukin (IL)-2 infusions. Viral load rebound 12 weeks after ART interruption was then analyzed to assess immune control. Fifty-two subjects reached the study end point. ALVAC recipients had 0.5 log(10) lower virologic rebounds (P=.033). IL-2 plus vaccine boosted CD4(+) T cell counts (P<.001) but did not diminish viral rebound. Significant changes were not detected for HIV-specific lymphoproliferative responses in any arm. This exploratory protocol provides useful clinical data for future therapeutic immunization trial design. Copyright © 2006 Infectious Diseases Society of America [ABSTRACT FROM AUTHOR]

Abstract: Racial/ethnic minorities and women are under-represented in AIDS clinical trials (ACTs). We examined gender differences in willingness to participate in ACTs among urban HIV-infected individuals (N=286). Sixty percent of participants were male, and most were from racial/ethnic minority backgrounds (55% African-American, 34% Latino/Hispanic, 11% White/other). Knowledge of ACTs was poor. Males and females did not differ substantially in their distrust of AIDS scientists, or in barriers to ACTs. Almost all (87%) were somewhat or very willing to join ACTs. Females were less willing than males to join, including trials testing new medications or new medication combinations. Males and females differed in correlates of willingness to participate in ACTs. Despite long-standing barriers to medical research among minorities and women, willingness to participate was substantial, particularly for men, although the factors that might motivate them to join differed by gender. Women appeared more averse to trials involving new anti-retroviral regimens than men. Gender-specific outreach, behavioural intervention, and social marketing efforts are needed.

Abstract: Background. The ability to control human immunodeficiency virus (HIV) replication in vivo in the absence of antiretroviral therapy (ART) is a measure of the efficiency of antiviral immunity. In a study of patients with chronic, ART-suppressed HIV infection, AIDS Clinical Trials Group 5068 investigated the effects of immunization with an exogenous HIV vaccine and pulse exposure to the subject's unique viral epitopes, by means of structured treatment interruptions (STIs), on the dynamics of viral rebound during a subsequent analytical treatment interruption (ATI). Methods. Ninety-seven subjects receiving stable ART with an HIV-1 RNA load <50 copies/mL and CD4(+) T lymphocyte count >400 cells/mm(3) were randomized to undergo continued ART, STIs, ALVAC-HIV vCP1452 immunization, or STIs and ALVAC-HIV vCP1452 immunization. Results. Subjects in the 2 STI arms had a significantly longer median doubling time in the period of the initial rise of viral load, a significantly lower median peak viral load, a significantly lower median end-of-ATI viral load set point, and a greater proportion of subjects with an end-of-ATI viral load set point <1000 copies/mL, compared with the subjects in the 2 arms without STIs. With an immunization schedule of 3 sets of 3 weekly injections, ALVAC-HIV vCP1452 did not affect viral load measures. Conclusions. In this randomized, controlled study of intermittent STI as a therapeutic autoimmunization strategy, evidence of enhanced immunologic control of HIV replication was demonstrated.

Abstract: To examine the extent of immune reconstitution in treatment-naive patients with CD4 T-cell counts <500 cells/μL following 48 weeks of highly active antiretroviral therapy (HAART). Thirteen antiretroviral naive patients were evaluated longitudinally for 48 weeks on HAART utilizing immune functional and lymphocyte phenotyping assays, including lymphocyte proliferation assay, flow cytometric evaluation of cell surface markers, and delayed type hypersensitivity skin tests. Virologic responses were monitored using commercially available viral load assays and gag/pol mRNA quantification using simultaneous immunophenotyping/UltraSensitive fluorescence in situ hybridization (ViroTect In Cell HIV-1 Detection Kit; Invirion, Frankfort, MI). Thymic function was evaluated for a subset of four patients using real-time polymerase chain reaction (PCR) for T-cell receptor excision circle (TREC) quantification and thymic scans using computerized axial tomography (CT) of the thymus. HAART initiation resulted in a significant decline in plasma viremia and percentage of infected peripheral blood cells, and a rise in CD4 T cells from a baseline median of 207 cells/μL to a week-48 median of 617 cells/μL. The rise was predominately in CD4 memory cells. Naive T cells also increased in number, but at a slower rate. Activated (HLA-DR CD38) CD4 and CD8 T cells were elevated at baseline (24 and 62%, respectively) and declined by week 48 (17 and 36%, respectively) but did not reach normal levels. The number of Fas CD4 T cells increased from a baseline median of 169 to 381 cells/μL at week 48. Both soluble interleukin (IL)-2 and tumour necrosis factor (TNF) II receptors declined by week 48. HIV p24 lymphocyte proliferation assay responses were transiently detected in three patients. TREC values increased from a median 6400 copies/μg at baseline to a week-48 median value of 26 697 copies/μg. Immune functional reconstitution was not achieved in these HAART naive patients.

Abstract: Antiretroviral monotherapy for initial drug characterization risks the selection of resistant virus, yet monotherapy is the only setting where many fundamental properties of a new drug can be reliably determined. Using data on viral replication kinetics and dynamics, we designed an accelerated (14 day) open-label study of single agent emtricitabine (formerly known as FTC)—a nucleoside reverse transcriptase inhibitor—to select a dosing regimen for further therapeutic study. Five regimens (25 mg bd, 100 mg od, 200 mg od, 100 mg bd and 200 mg bd) were evaluated in HIV-1-infected subjects over a 14 day dosing period to determine the optimal dose and pharmacokinetics. Serial blood samples for virological, pharmacokinetic and intracellular FTC-triphosphate measurements were drawn frequently. A dose–response relationship for the antiviral activity of emtricitabine was established, with total daily doses of 200 mg or more producing the greatest median HIV-1 viral load suppression: 1.72–1.92 log10. Based on virological outcomes, dose–response analysis and intracellular triphosphate levels, a once-daily dose of 200 mg was selected for further long-term clinical study. Adverse events possibly related to emtricitabine were unremarkable. The antiviral activity of emtricitabine correlated well with intracellular FTC-triphosphate concentrations. This study design is a safe, useful tool for early dose selection for drugs with potent antiretroviral activity and linear pharmacokinetics. [ABSTRACT FROM PUBLISHER]

Abstract: Six patients (11 eyes) with virologically confirmed cytomegalovirus (CMV) retinitis involving the posterior pole of the eye were treated with a new drug, ganciclovir. Treatment with intravenous ganciclovir consistently halted progression of retinitis and produced improvement in measures of visual function. However, within three weeks after cessation of therapy renewed CMV activity and worsening of visual function were observed in most cases. Maintenance therapy with ganciclovir extended the period of remission from CMV retinitis. [ABSTRACT FROM PUBLISHER]

Abstract: Two homosexual males with the "gay bowel syndrome' experienced an acute unilateral loss of vision. Both patients had white intraretinal lesions, which became confluent. One of the cases had a depressed cell-mediated immunity; both patients ultimately died after a prolonged illness. In one patient cytomegalovirus was cultured from a vitreous biopsy. Autopsy revealed disseminated cytomegalovirus in both patients. Widespread retinal necrosis was evident, with typical nuclear and cytoplasmic inclusions of cytomegalovirus. Electron microscopy showed herpes virus, while immunoperoxidase techniques showed cytomegalovirus. The altered cell-mediated response present in homosexual patients may be responsible for the clinical syndromes of Kaposi's sarcoma and opportunistic infection by Pneumocystis carinii, herpes simplex, or cytomegalovirus.

Abstract: The in-vitro activities of five investigational antibiotics, RP59500 (a semisynthetic injectable streptogramin), CL 329,998 and CL 331,002 (two new glycylcyclines), trovafloxacin (a naphthyridone), and clinafloxacin (a dihalogenated quinolone), were examined and compared with those of minocycline, teicoplanin and vancomycin against 190 clinical isolates of Gram-positive cocci. The MICs for RP59500 against all isolates with the exception of Enterococcus faecalis were low. RP59500 was bactericidal against all except enterococcal isolates. CL 329,998 and CL 331,002 were significantly more active than minocycline against oxacillin-resistant Staphylococcus aureus (MIC90 0.25 versus 8 mg/L) and all enterococcal isolates (MIC90 0.125 versus 16 mg/L). Clinafloxacin was the most active agent against all staphylococcal isolates and was bactericidal. Trovafloxacin showed good activity against oxacillin-susceptible staphylococci and alpha-haemolytic streptococci (MIC90 < or = 0.125 mg/L). This study demonstrates the potential of the five investigational antibiotics as therapeutic agents for infections caused by Gram-positive cocci. [ABSTRACT FROM AUTHOR]

Abstract: Central-nervous-system toxoplasmosis developed in 7 of 269 patients with the acquired immunodeficiency syndrome reported to the New York City Health Department through July 1982. Focal neurologic abnormalities, mass lesions on computed-tomographic brain scans, lymphocytic cerebrospinal fluid pleocytosis, and detectable IgG antibody to Toxoplasma gondii were common; but IgG titers of 1:1024 or more, IgM antibody to T. gondii, and positive open brain biopsies were uncommon. Serologic findings suggested that the disease resulted from recrudescent rather than primary infection. Four of five patients improved when treated with sulfonamides and pyrimethamine, but 2 had relapses. An aggressive diagnostic approach and sometimes even empiric therapy are warranted when central-nervous-system toxoplasmosis is suspected in a seropositive patient with the acquired immunodeficiency syndrome.

Abstract: We examined the long-term safety and efficacy of zidovudine therapy in 229 subjects with acquired immunodeficiency syndrome (AIDS) and AIDS-related complex who previously participated in a placebo-controlled study of zidovudine. One hundred two placebo recipients (delayed treatment group) and 127 zidovudine recipients (original treatment group) were followed up while receiving zidovudine therapy for a mean of 21 months. Survival rates for the original treatment group were 84.5% and 57.6% at 12 and 21 months, respectively; for the delayed treatment group, 78.8% and 64.6% at 12 and 21 months, respectively, and 78.8% and 47.5% at 12 and 21 months, respectively, for 77 subjects with AIDS and 93.0% and 71.8%, respectively, for 50 subjects with AIDS-related complex in the original treatment group. Adverse reactions decreased over time and newly observed toxic reactions were unusual. The clinical course of these subjects suggests continued survival benefits with long-term zidovudine therapy.

Abstract: Intravenous drug users are the second largest group to develop the acquired immunodeficiency syndrome, and they are the primary source for heterosexual and perinatal transmission in the United States and Europe. Understanding long-term trends in the spread of human immunodeficiency virus among intravenous drug users is critical to controlling the acquired immunodeficiency syndrome epidemic. Acquired immunodeficiency syndrome surveillance data and seroprevalence studies of drug treatment program entrants are used to trace seroprevalence trends among intravenous drug users in the borough of Manhattan. The virus entered this drug-using group during the mid-1970s and spread rapidly in 1979 through 1983. From 1984 through 1987, the seroprevalence rate stabilized between 55% and 60%--well below hepatitis B seroprevalence rates. This relatively constant rate is attributed to new infections, new seronegative persons beginning drug injection, seropositive persons leaving drug injection, and increasing conscious risk reduction.

Abstract: Background:Antiretroviral regimens with simplified dosing and better safety are needed to maximize the efficiency of antiretroviral delivery in resource-limited settings. We investigated the efficacy and safety of antiretroviral regimens with once-daily compared to twice-daily dosing in diverse areas of the world.Methods and Findings:1,571 HIV-1-infected persons (47% women) from nine countries in four continents were assigned with equal probability to open-label antiretroviral therapy with efavirenz plus lamivudine-zidovudine (EFV+3TC-ZDV), atazanavir plus didanosine-EC plus emtricitabine (ATV+DDI+FTC), or efavirenz plus emtricitabine-tenofovir-disoproxil fumarate (DF) (EFV+FTC-TDF). ATV+DDI+FTC and EFV+FTC-TDF were hypothesized to be non-inferior to EFV+3TC-ZDV if the upper one-sided 95% confidence bound for the hazard ratio (HR) was â‰¤1.35 when 30% of participants had treatment failure.An independent monitoring board recommended stopping study follow-up prior to accumulation of 472 treatment failures. Comparing EFV+FTC-TDF to EFV+3TC-ZDV, during a median 184 wk of follow-up there were 95 treatment failures (18%) among 526 participants versus 98 failures among 519 participants (19%; HR 0.95, 95% CI 0.72-1.27; p = 0.74).

30. Antibiotic Treatment Failure and Associated Outcomes Among Adult Patients With Community-Acquired Pneumonia in the Outpatient Setting: A Real-world US Insurance Claims Database Study.

Author: Tillotson G, Lodise T, Classi P, Mildvan D, and McKinnell JA
Abstract: Background: Antibiotic treatment failure is common among patients with community-acquired pneumonia (CAP) who are managed in the outpatient setting and is associated with higher mortality and increased health care costs. This study's objectives were to quantify the occurrence of antibiotic treatment failure (ATF) and to evaluate clinical and economic outcomes between CAP patients who experienced ATF relative to those who did not., Methods: Retrospective analysis of the MarketScan Commercial & Medicare Supplemental Databases was performed, identifying patients ≥18 years old, with a pneumonia diagnosis in the outpatient setting, and who received a fluoroquinolone, macrolides, beta-lactam, or tetracycline. ATF was defined as any of the following events within 30 days of initial antibiotic: antibiotic refill, antibiotic switch, emergency room visit, or hospitalization. Outcomes included 30-day all-cause mortality and CAP-related health care costs., Results: During the study period, 251 947 unique patients met inclusion criteria. The mean age was 52.2 years, and 47.7% were male. The majority of patients received a fluoroquinolone (44.4%) or macrolide (43.6%). Overall, 22.1% were classified as ATFs. Among 18-64-year-old patients, 21.2% experienced treatment failure, compared with 25.7% in those >65 years old. All-cause mortality was greater in the antibiotic failure group relative to the non-antibiotic failure group (18.1% vs 4.6%, respectively), and the differences in 30-day mortality between antibiotic failure groups increased as a function of age. Mean 30-day CAP-related health care costs were also higher in the patients who experienced treatment failure relative to those who did not ($2140 vs $54, respectively)., Conclusions: Treatment failure and poor outcomes from outpatient CAP are common with current guideline-concordant CAP therapies. Improvements in clinical management programs and therapeutic options are needed., (© The Author(s) 2020. Published by Oxford University Press on behalf of Infectious Diseases Society of America.)

Abstract: Nationally up to 60 % of persons living with HIV are neither taking antiretroviral therapy (ART) nor well engaged in HIV care, mainly racial/ethnic minorities. This study examined a new culturally targeted multi-component intervention to address emotional, attitudinal, and social/structural barriers to ART initiation and HIV care. Participants (N = 95) were African American/Black and Latino adults with CD4 < 500 cells/mm(3) not taking ART, randomized 1:1 to intervention or control arms, the latter receiving treatment as usual. Primary endpoints were adherence, evaluated via ART concentrations in hair samples, and HIV viral load suppression. The intervention was feasible and acceptable. Eight months post-baseline, intervention participants tended to be more likely to evidence "good" (that is, 7 days/week) adherence (60 vs. 26.7 %; p = 0.087; OR = 3.95), and had lower viral load levels than controls (t(22) = 2.29, p = 0.032; OR = 5.20), both large effect sizes. This highly promising intervention merits further study.

Abstract: African American/Black and Hispanic persons living with HIV/AIDS ("AABH-PLHA") are under-represented in HIV/AIDS medical studies (HAMS). This paper evaluates the efficacy of a social/behavioral intervention to increase rates of screening for and enrollment into HAMS in these populations. Participants (N = 540) were enrolled into a cluster randomized controlled trial of an intervention designed to overcome multi-level barriers to HAMS. Primary endpoints were rates of screening for and enrollment into therapeutic/treatment-oriented and observational studies. Intervention arm participants were 30 times more likely to be screened than controls (49.3 % vs. 3.7 %; p < .001). Half (55.5 %) of those screened were eligible for HAMS, primarily observational studies. Nine out of ten found eligible enrolled (91.7 %), almost all into observational studies (95.2 %), compared to no enrollments among controls. Achieving appropriate representation of AABH-PLHA in HAMS necessitates modification of study inclusion criteria to increase the proportion found eligible for therapeutic HAMS, in addition to social/behavioral interventions.

33. HIV-Infected Individuals Who Delay, Decline, or Discontinue Antiretroviral Therapy: Comparing Clinic- and Peer-Recruited Cohorts.

Author: Gwadz M, Applegate E, Cleland C, Leonard NR, Wolfe H, Salomon N, Belkin M, Riedel M, Banfield A, Sanfilippo L, Wagner A, and Mildvan D
Abstract: A substantial proportion of persons living with HIV/AIDS (PLHA) delay, decline, or discontinue antiretroviral therapy (ART) when it is medically indicated (40-45%), largely African-Americans and Latinos/Hispanics. This study explores the feasibility of locating PLHA, who are not on ART (PLHA-NOA) through clinics and peer-referral; compares the two cohorts on multi-level barriers to ART; and examines readiness to initiate/reinitiate ART, a predictor of treatment outcomes. We recruited adult HIV-infected African-American and Latino/Hispanic PLHA-NOA through HIV hospital clinics and peer-referral in 2012-2013. Participants were engaged in structured 1-h assessments with reliable/valid measures on barriers to ART. We found that recruitment through peers (63.2%, 60/95) was more feasible than in clinics (36.8%, 35/90). Participants were 48.0 years old and had lived with HIV for 14.7 years on average, and 56.8% had taken ART previously. Most (61.1%) were male and African-American (76.8%), and 23.2% were Latino/Hispanic. Peer-recruited participants were older, had lived with HIV longer, were less engaged in HIV care, and were more likely to have taken ART previously. The cohorts differed in reasons for discontinuing ART. Levels of ART knowledge were comparable between cohorts (68.5% correct), and there were no differences in attitudes toward ART (e.g., mistrust), which were in the neutral range. In bivariate linear regression, readiness for ART was negatively associated with physician mistrust (B = -10.4) and positively associated with self-efficacy (B = 5.5), positive outcome expectancies (B = 6.3), beliefs about personal necessity of ART (B = 17.5), and positive internal norms (B = 7.9). This study demonstrates the feasibility of engaging this vulnerable population through peer-referral. Peer-recruited PLHA evidence particularly high rates of risk factors compared to those in hospital clinics. Interventions to support ART initiation and continuation are sorely needed for both subgroups.

Abstract: A 29-year-old Japanese man developed fever, nausea, vomiting, diarrhoea, right lower quadrant abdominal pain and rebound tenderness. With the clinical suspicion of appendicitis, an abdominal CT scan was performed, which revealed mesenteric lymphadenitis. The patient was hospitalised and treated with antibiotics, but was ultimately found to have Kikuchi-Fujimoto disease (KFD). This diagnosis was facilitated by the use of positron emission tomography scan that identified an accessible inguinal lymph node for biopsy and histopathological evaluation. Invasive abdominal surgery was thereby averted and the patient made a complete recovery on subsequent follow-up. Review of the published literature reveals that pseudoappendicitis due to KFD is a rare occurrence that has generally required abdominal surgery to establish the diagnosis, thus supporting the potential value of the approach taken here., (2014 BMJ Publishing Group Ltd.)

Abstract: A retrospective cohort study was performed on 175 adult patients treated for community-acquired pneumonia with moxifloxacin or ceftriaxone/azithromycin in a nonintensive care unit. Both cohorts were very similar with regard to a wide range of characteristics including age, severity of disease, comorbidities, length of stay, and mortality. Multidrug-resistant organisms were subsequently isolated from 6 (15%) moxifloxacin-treated patients and 5 (4%) ceftriaxone/azithromycin-treated patients within 90 days after beginning of therapy (P = .026 on logistic regression analysis)., (Copyright © 2014 Association for Professionals in Infection Control and Epidemiology, Inc.

Abstract: Background and Objective: The reasons for minority underrepresentation in HIV/AIDS clinical trials remain unclear. We aimed to evaluate the knowledge, experience, and factors that influence minority participation in HIV/AIDS studies in the United States., Methods: An anonymous, bilingual, self-administered survey on study participation was given to HIV-infected adults attending AIDS Clinical Trials Group-affiliated clinics in the United States and Puerto Rico. Chi-square tests were used to evaluate differences by race, first language, and level of education. Logistic regression was used to estimate odds ratio (OR) and 95% confidence interval (CI) for factors associated with being talked to about participation in a study., Results: We analyzed 2,175 complete surveys (221 in Spanish). Among respondents, 31% were White, 40% were Black/African American (AA), and 21% were Hispanic. The overall rate of previous participation in any HIV/AIDS study was 48%. Hispanics were less likely to know about studies compared to Whites and AAs (67% vs 74% and 76%, respectively; P < .001). Compared to Whites, AAs and Hispanics were less likely to have been talked to about participating in a study (76% vs 67% and 67%, respectively; P < .001). The OR for being talked to about participating in a study was 0.65 (95% CI, 0.52-0.81) for AAs and 0.65 (95% CI, 0.49-0.85) for Hispanics, compared to Whites. AAs and Hispanics were more likely to state that studies were not friendly to their race (17% and 10% vs 4%; P < .001)., Conclusions: Minorities continue to face barriers for HIV/AIDS trial participation, even when clinical research is available. Enrollment strategies should better target minorities to improve recruitment in HIV/AIDS research.

Abstract: We performed a nested case-control study (ratio of 1:4) on the emergence of tigecycline-resistant multidrug-resistant Klebsiella pneumoniae (TR-MDRKP) isolates among patients who initially presented with a tigecycline-susceptible MDRKP isolate. Out of 260 patients, 24 (9%) had a subsequent clinical culture positive for a TR-MDRKP isolate within the 90-day follow-up period. On logistic regression analyses, receipt of tigecycline (adjusted odds ratio [OR], 5.06; 95% confidence interval [CI], 1.80 to 14.23; P = 0.002) was the only independent predictor of subsequent isolation of a TR strain.

Abstract: Background: Pegylated interferon (PEG-IFN)/ribavirin (RBV)-related cytopenias have been associated with improved virological outcomes among hepatitis C virus (HCV)-monoinfected patients. This analysis evaluated PEG-IFN/RBV-related cytopenias with virological responses among HIV/HCV-coinfected patients., Methods: Pooled data from PARADIGM and AIDS Pegasys Ribavirin International CO-infection Trial (APRICOT) trials of HIV/HCV-infected patients treated with PEG-IFN/RBV. Virologic response was categorized as HCV RNA detectable (end of treatment nonresponders [ET-NR]) or nondetectable (end of treatment responders [ETR]). Declines in hemoglobin (Hgb), platelets, neutrophils, lymphocytes, and weight between the groups were compared via analysis of covariance and Cochran-Mantel-Haenszel test., Results: A total of 474 patients, 291 ET-NR and 183 ETR (67 relapsers, 116 with sustained virologic response), 81% male, 52% Caucasian, 88% noncirrhotic, and 67% nondetectable HIV. The ETR experienced greater Hgb declines (≥3.0 g/dL) from baseline (73.8% versus 55.0%; P < .0001), neutrophils ≤1 and ≤ 0.5 × 10(9)/L (66.1% versus 56.4%; P = .0334 and 42.6% versus 33.3%; P = .0312, respectively), and lymphocytes ≤1.5 and ≤0.5 × 10(9)/L (99.5% versus 87.6%; P < .0001 and 24.6% versus 14.9%; P =.0079, respectively)., Conclusions: The HIV/HCV-coinfected patients with ETR experienced greater declines in Hgb, neutrophils, and lymphocytes than the ET-NR patients.

39. Catfish spine envenomation and bacterial abscess with Proteus and Morganella: a case report.

Author: Huang G, Goldstein R, and Mildvan D
Abstract: Introduction: Abscess formation and cellulitis in the setting of envenomation are rare complications of handling catfish. To the best of our knowledge, isolation of Proteus vulgaris has not been previously recorded, and recovery of Morganella morganii has been reported in only one prior case from wound cultures in patients injured by catfish stings. We report a case of catfish envenomation characterized by abscess formation and cellulitis, in which wound cultures grew these unusual organisms., Case Presentation: A 52-year-old Chinese-American man was hospitalized with erythema and swelling of his right arm of 10 days' duration after skin penetration by a catfish barb. An abscess of his right thumb had undergone incision and drainage, with purulent drainage sent for wound culture immediately prior to admission. Laboratory studies revealed elevated white blood count, sedimentation rate, and C-reactive protein. The patient was treated with intravenous ampicillin-sulbactam and vancomycin during his hospitalization, and symptoms improved. Wound cultures obtained prior to presentation grew many Proteus vulgaris and Morganella morganii. He was subsequently discharged on a 10-day course of oral ciprofloxacin and amoxicillin-clavulanate. At a 12-month telephone follow-up, the patient denied developing further symptoms and reported that the wound had healed completely without complication., Conclusion: Although envenomation and secondary infection are not uncommon sequelae of handling catfish, the present case is unique by virtue of the infecting organisms isolated. Given the prevalence of injury from catfish stings, a review of the literature is presented in order to provide recommendations for prevention and treatment of catfish envenomation.

Abstract: Objective: This study was performed to evaluate a once-daily dual-therapy regimen, maraviroc (MVC) + atazanavir/ritonavir (ATV/r), in treatment-naive patients., Design: A phase 2b, randomized, open-label pilot study., Methods: In Study A4001078 (NCT00827112), treatment-naive patients with CCR5-tropic HIV-1 (HIV-1 RNA ≥1000 copies/mL; CD4 cell count ≥100 cells/mm) were randomized to receive either MVC 150 mg once daily (n = 60) or tenofovir/emtricitabine (TDF/FTC) 300/200 mg once daily (n = 61) + ATV/r 300/100 mg once daily. Primary endpoint was proportion of patients with HIV-1 RNA <50 copies per milliliter at week 48., Results: At week 48, 44 (74.6%) and 51 (83.6%) patients in the MVC and TDF/FTC treatment groups, respectively, had plasma HIV-1 RNA <50 copies per milliliter. Median change from baseline in CD4 cell count at week 48 was +173 and +187 cells per cubic millimeter with MVC and TDF/FTC, respectively. Seven patients discontinued from each arm; there were no deaths. The incidence of serious adverse events (AEs) was similar in each group; however, there were more grade 3/4 AEs in the MVC group (18 vs 11), mostly due to hyperbilirubinemia. Three patients in each arm were evaluable for virological analysis at discontinuation or failure (HIV-1 RNA >500 copies/mL); no genotypic resistance, change in tropism, or loss of susceptibility relevant to treatment was observed., Conclusions: The virological activity and immunological benefit of once-daily MVC + ATV/r were confirmed. Indirect hyperbilirubinemia and associated signs were the most commonly reported AEs in both study treatment groups and were not associated with significant transaminase increases. No drug resistance occurred.

Abstract: African-American and Latino/Hispanic persons living with HIV/AIDS are underrepresented in AIDS clinical trials (ACTs). The aim of this paper was to uncover factors, either unmodifiable or not directly targeted for change, that predicted screening for ACTs during an efficacious peer-driven intervention (N = 540 total; N = 351 in an intervention arm, N = 189 control). This paper focused on participants assigned to an intervention arm, 56 % of whom were screened for ACTs. We found a decreased odds of screening was associated with closer proximity to the screening site, gay/lesbian orientation, lower mental health symptoms, current injection drug use, more recent HIV diagnosis, lack of prior screening experience, and failure to attend all intervention sessions, but there were no gender or racial/ethnic differences. Efforts to reduce racial/ethnic disparities in ACTs can be enhanced by attending to these specific factors, which may interfere with programmatic efforts to increase African-American and Latino/Hispanic representation in ACTs.

Abstract: Objectives: We examined the efficacy of a peer-driven intervention to increase rates of screening for AIDS clinical trials among African Americans and Hispanics living with HIV/AIDS., Methods: We used a randomized controlled trial design to examine the efficacy of peer-driven intervention (6 hours of structured sessions and the opportunity to educate 3 peers) compared with a time-matched control intervention. Participants were recruited using respondent-driven sampling (n = 342; 43.9% female; 64.9% African American, 26.6% Hispanic). Most participants (93.3%) completed intervention sessions and 64.9% recruited or educated peers. Baseline and post-baseline interviews (94.4% completed) were computer-assisted. A mixed model was used to examine intervention effects on screening., Results: Screening was much more likely in the peer-driven intervention than in the control arm (adjusted odds ratio [AOR] = 55.0; z = 5.49, P < .001); about half of the participants in the intervention arm (46.0%) were screened compared with 1.6% of controls. The experience of recruiting and educating each peer also increased screening odds among those who were themselves recruited and educated by peers (AOR = 1.4; z = 2.06, P < .05)., Conclusions: Peer-driven intervention was highly efficacious in increasing AIDS clinical trial screening rates among African Americans and Hispanics living with HIV/AIDS.

Abstract: Persons living with HIV/AIDS (PLHA) of color are under-represented in AIDS clinical trials (ACTs), which may limit the generalizability of research findings and denies many individuals access to high levels of care and new treatments available through ACTs. Disproportionately low rates of recruitment in health care settings and by providers are a major barrier to ACTs for this group. Moreover, PLHA of color are more likely than their white peers to decline to participate, mainly due to fear and mistrust (although willingness is also high), negative social norms about ACTs, and difficulty navigating the unfamiliar ACT system. We describe a small number of successful behavioral and structural interventions to increase the participation of PLHA of color in screening for and enrollment into ACTs. HIV care settings, clinical trials sites, and trial sponsors are uniquely positioned to develop procedures, supports, and trials to increase the proportion of PLHA of color in ACTs.

Abstract: Individuals from racial/ethnic minority backgrounds and women have not been proportionately represented in AIDS clinical trials (ACTs). There have been few intervention efforts to eliminate this health disparity. This paper reports on a brief behavioral intervention to increase rates of screening for ACTs in these groups. The study was exploratory and used a single-group pre/posttest design. A total of 580 persons living with HIV/AIDS (PLHA) were recruited (39% female; 56% African-American, 32% Latino/Hispanic). The intervention was efficacious: 25% attended screening. We identified the primary junctures where PLHA are lost in the screening process. Both group intervention sessions and an individual contact were associated with screening. Findings provide preliminary support for the intervention's efficacy and the utility of combining group and individual intervention formats. Interventions of greater duration and intensity, and which address multiple levels of influence (e.g., social, structural), may be needed to increase screening rates further.

Abstract: Background: Pathogenesis studies show that naive CD4 cells are preferentially depleted in lymphoid tissues during HIV infection, and studies of advanced patients suggest levels of naive CD4 cells in blood correlate to total CD4 cells after starting antiretroviral therapy (ARV). We hypothesized that measuring naive CD4 cells in blood in people at earlier stages of disease would identify those at highest risk for poor CD4 reconstitution who may benefit from earlier initiation of ARV., Methods and Findings: We identified 348 patients from multiple AIDS Clinical Trials Group studies who were ARV naive, had a CD4 count between 200 and 500 cells per microliter, a measure of pretreatment-naive CD4 percent, and serial follow-up measures of CD4 count and plasma HIV RNA after starting ARV. We used logistic regression to model the ability of naive CD4 percent to predict 100 and 200 CD4 cell increases after 24 months of therapy. After controlling for baseline viral load and demographic variables, baseline naive but not total CD4 cell count strongly predicted CD4 cell increases. Lower baseline naive CD4 percent was associated with greater time spent at lower CD4 T-cell counts after initiating ARV., Conclusions: Measurement of naive CD4 percent in patients can identify those least likely to reconstitute immunity, who may benefit from earlier ARV treatment.

Abstract: Acute human immunodeficiency virus type 1 (HIV-1) infection is characterized by high levels of immune activation. Immunomodulation with cyclosporine combined with antiretroviral therapy (ART) in the setting of acute and early HIV-1 infection has been reported to result in enhanced immune reconstitution. Fifty-four individuals with acute and early infection were randomized to receive ART with 4 weeks of cyclosporine versus ART alone. In 48 subjects who completed the study, there were no significant differences between treatment arms in levels of proviral DNA or CD4(+) T cell counts. Adjunctive therapy with cyclosporine in this setting does not provide apparent virologic or immunologic benefit.

To compare efficacy of once-daily (QD) versus twice-daily (BID) antiretroviral therapy, we randomized human immunodeficiency virus (HIV)-positive, treatment-naive patients to lopinavir-ritonavir (LPV/r) administered at a dosage of 400 mg of lopinavir and 100 mg of ritonavir BID (n = 160) or 800 mg of lopinavir and 200 mg of ritonavir QD (n = 161), plus either emtricitabine 200 mg QD and extended-release stavudine at a dosage of 100 mg QD or tenofovir at a dosage of 300 mg QD. Randomization was stratified by screening HIV RNA level <100,000 copies/mL versus > or = 100,000 copies/mL. The primary efficacy end point was sustained virologic response (SVR; defined as reaching and maintaining an HIV RNA level <200 copies/mL) through week 48., Results: Subjects were 78% male, 33% Hispanic, and 34% black. A total of 82% of subjects completed the study, and 71% continued to receive the initially assigned dosage schedule. The probability of SVR did not differ significantly for the BID versus QD comparison, with an absolute proportional difference of 0.03 (95% confidence interval [CI], -0.07 to 0.12). The comparison depended on the screening RNA stratum (P=.038); in the higher RNA stratum, the probability of SVR was significantly better in the BID arm than in the QD arm: 0.89 (95% CI, 0.79-0.94) versus 0.76 (95% CI, 0.64-0.84), a difference of 0.13 (95% CI, 0.01-0.25). Lopinavir trough plasma concentrations were higher with BID dosing. Adherence to prescribed doses of LPV/r was 90.6% in the QD arm versus 79.9% in the BID arm (P<.001). Conclusions. Although subjects assigned to QD regimens had better adherence, overall treatment outcomes were similar in the QD and BID arms. Subjects with HIV RNA levels > or =100,000 copies/mL had better SVR with BID regimens at 48 weeks, which suggests a possible advantage in this setting for more frequent dosing.
