INTRODUCTION Interruptions in treatment pose risks for people with HIV (PWH) and threaten progress in ending the HIV epidemic; however, the COVID-19 pandemic's impact on HIV service delivery across diverse settings is not broadly documented. METHODS From September 2020 to March 2021, the International epidemiology Databases to Evaluate AIDS (IeDEA) research consortium surveyed 238 HIV care sites across seven geographic regions to document constraints in HIV service delivery during the first year of the pandemic and strategies for ensuring care continuity for PWH. Descriptive statistics were stratified by national HIV prevalence (

Indian economy is a fifth largest developing economy. It has been grown in between the periods of time (1991 – 2016) India’s GDP stood at Rs 5,862,120 million in 1991 and in 2016 it was at Rs 1,35,760,860 million economy with 2, 216 percent growth. At the same time, global disparities are growing with industrially and technologically more advanced countries by accessing the ever increased digital technologies, online platforms, data analytics, automation and robotics and capitalizing the globalized opportunities. Hence, as a second highly populated country like India should access the technologies to promote various start-ups in to globalized established corporations for economic development and to be the second largest economy in the world by 2050. The start-ups support and help to absorb productive resources at all levels of the economy. It contributes to the creation of resilient economic systems in which start-ups ecosystems and small and large firms are interlinked. Such increasing linkages support, attract foreign direct investment and investing transnational corporations seek reliable domestic suppliers for their supply chains. In agriculture and allied sector start-ups also have a potential to empower millions of farmers and farm women to address the food and nutrition security, livelihood security and other sustainable development goals. But still funding activities are the biggest driving factors in the start-up ecosystem. Hence, appropriate funds and other assistance may enrich the start-up ecosystem to boost up the Indian economy in the globalized platforms. So, the CSR funds plays very important source to capitalize the start-up ecosystem in to sustainable development based economic ecosystems.

Groundwater resources plays important role in agro-biodiversity and environmental conservation perspectives. Surface and groundwater have played a significant role in the agrarian economics in the developing economics particularly in India. At the same time, the tropical and sub-tropical India is the largest groundwater user in the world through unregulated construction and utilization of millions of private wells in the last five decades exploited groundwater availability and sustainable regeneration issues. Hence, in order to improve the surface and groundwater conservation, regeneration, management and protection for sustainable utilization of Groundwater requires a participatory and coordinated action. Nationwide, many national and regional Non Government Organisations (NGOs) are functioning in the line of effective surface and ground water management the community. The recent Geographical Information Systems (GIS) based technologies also supports for drought mitigation and climate change adaptation. This study highlights the important NGOs led sustainable Groundwater management practices under various local hydro geological settings and agro economic realities for up scaling the community driven sustainable Groundwater management.

Objectives Integration of HIV and non-communicable disease services improves the quality and efficiency of care in low- and middle-income countries (LMICs). We aimed to describe current practices for the screening and management of atherosclerotic cardiovascular disease (ASCVD) among adult HIV clinics in Asia. Methods Sixteen LMIC sites included in the International Epidemiology Databases to Evaluate AIDS - Asia-Pacific network were surveyed. Results Sites were mostly (81%) based in urban public referral hospitals. Half had protocols to assess tobacco and alcohol use. Protocols for assessing physical inactivity and obesity were in place at 31% and 38% of sites, respectively. Most sites provided educational material on ASCVD risk factors (between 56% and 75% depending on risk factors). A total of 94% reported performing routine screening for hypertension, 100% for hyperlipidaemia and 88% for diabetes. Routine ASCVD risk assessment was reported by 94% of sites. Protocols for the management of hypertension, hyperlipidaemia, diabetes, high ASCVD risk and chronic ischaemic stroke were in place at 50%, 69%, 56%, 19% and 38% of sites, respectively. Blood pressure monitoring was free for patients at 69% of sites; however, most required patients to pay some or all the costs for other ASCVD-related procedures. Medications available in the clinic or within the same facility included angiotensin-converting enzyme inhibitors (81%), statins (94%) and sulphonylureas (94%). Conclusion The consistent availability of clinical screening, diagnostic testing and procedures and the availability of ASCVD medications in the Asian LMIC clinics surveyed are strengths that should be leveraged to improve the implementation of cardiovascular care protocols.

Objectives Early mortality among those still initiating antiretroviral therapy (ART) with advanced stages of HIV infection in resource-limited settings remains high despite recommendations for universal HIV treatment. We investigated risk factors associated with early mortality in people living with HIV (PLHIV) starting ART at low CD4 levels in the Asia-Pacific. Methods PLHIV enrolled in the Therapeutics, Research, Education and AIDS Training in Asia (TREAT Asia) HIV Observational Database (TAHOD) who initiated ART with a CD4 count 1 year were censored at 12 months. Competing risk regression was used to analyse risk factors with loss to follow-up as a competing risk. Results A total of 1813 PLHIV were included in the study, of whom 74% were male. With 73 (4%) deaths, the overall first-year mortality rate was 4.27 per 100 person-years (PY). Thirty-eight deaths (52%) were AIDS-related, 10 (14%) were immune reconstituted inflammatory syndrome (IRIS)-related, 13 (18%) were non-AIDS-related and 12 (16%) had an unknown cause. Risk factors included having a body mass index (BMI) 100 cells/μL: SHR 0.12; 95% CI 0.05-0.26) was associated with reduced hazard for mortality compared to CD4 count ≤ 25 cells/μL. Conclusions Fifty-two per cent of early deaths were AIDS-related. Efforts to initiate ART at CD4 counts > 50 cell/μL are associated with improved short-term survival rates, even in those with late stages of HIV disease.

Covishield (same as ChAdOx1) vaccine was rolled out in January 2021 against SARS-CoV2 in India. Although studies show good efficacy after two doses, there is limited data on the fate of the elicited antibody responses over time in groups with or without prior exposure to SARS-CoV2. Therefore, in this study we proposed to test naïve or previously exposed healthcare workers (HCWs) longitudinally after both doses for anti-SARS-CoV2 spike antibody (ASSA) levels. Serum samples were collected from 205 HCWs at days 14 and 28 after first dose, and at days 14, 28 and 3-months after second dose. ASSA levels were quantitated by ECLIA method. Non-responder rate was 17% (35/205) on day 14 and 2% (5/205) on day 28 after the first dose. After the second dose, the responder rate was 100%. Non-responder rate was significantly higher among males (p

Diabetes is a growing cause of morbidity and mortality in people living with HIV (PLHIV) receiving antiretroviral therapy (ART). We investigated the association between fasting plasma glucose (FPG) levels and mortality, and factors associated with FPG monitoring rates in Asia.Patients from the Therapeutics Research, Education, and AIDS Training in Asia (TREAT Asia) HIV Observational Database Low Intensity Transfer (TAHOD-LITE) cohort were included in the present study if they had initiated ART. Competing risk and Poisson regression were used to analyse the association between FPG and mortality, and assess risk factors for FPG monitoring rates, respectively. FPG was categorized as diabetes (FPG ≥ 7.0 mmol/L), prediabetes (FPG 5.6-6.9 mmol/L) and normal FPG (FPG 5.6 mmol/L).In total, 33 232 patients were included in the analysis. Throughout follow-up, 59% had no FPG test available. The incidence rate for diabetes was 13.7 per 1000 person-years in the 4649 patients with normal FPG at ART initiation. Prediabetes [sub-hazard ratio (sHR) 1.32; 95% confidence interval (CI) 1.07-1.64] and diabetes (sHR 1.90; 95% CI 1.52-2.38) were associated with mortality compared to those with normal FPG. FPG monitoring increased from 0.34 to 0.78 tests per person-year from 2012 to 2016 (P 0.001). Male sex [incidence rate ratio (IRR) 1.08; 95% CI 1.03-1.12], age 50 years (IRR 1.14; 95% CI 1.09-1.19) compared to ≤ 40 years, and CD4 count ≥ 500 cells/μL (IRR 1.04; 95% CI 1.00-1.09) compared to 200 cells/μL were associated with increased FPG monitoring.Diabetes and prediabetes were associated with mortality. FPG monitoring increased over time; however, less than half of our cohort had been tested. Greater resources should be allocated to FPG monitoring for early diabetic treatment and intervention and to optimize survival.

SARS-CoV2 is transmitted primarily through oral mouth secretions and respiratory droplets. Commercial mouthwashes, povidone iodine (PI), hydrogen peroxide (HP) and chlorhexidine (CHX) have been tested in cell culture and RT-PCR studies for their efficacy to reduce SARS-CoV2 burden. Here, we evaluated SARS-CoV2 burden in whole mouth fluid (WMF) and respiratory droplets (RD) samples before and after the use of PI, HP or CHX mouthwashes in hospitalized COVID-19 patients using RT-PCR and rapid antigen test (RAT). Thirty-six SARS-CoV2 RT-PCR-positive in-patients were randomly assigned to one of the four groups: 20 and 60 minutes after 1% w/v PI or 1.5% HP; 90 and 180 minutes after 1.5% HP or 0.2% w/v CHX. WMF and RD samples were collected concurrently at baseline and after the two different time points. RD (92%) showed a higher reduction in SARS-CoV2 burden than WMF samples (50%; p=0.008). SARS-CoV2 burden was statistically lower at both 20 minutes (p=0.02) and 60 minutes (p=0.03) with PI; at 20 minutes with HP (p=0.0001); and 90 minutes with CHX (p=0.04). The overall and individual mean logarithmic reductions in the WMF and RD samples were greater than 1.0 at 20, 60 and 90 minutes after PI, HP or CHX. RAT-positive patients at 90 minutes post-treatment (n=3) demonstrated a one log increase in virus copies. Among the three RAT-negative post-treatment patients, SARS-CoV2 burden declined by one log in two while the third patient had a slight increase in RNA copies. In conclusion, we have shown for the first time that the mouthwashes, PI, HP and CHX can reduce the SARS-CoV2 burden in the concurrently collected RD and WMF samples. RAT is more appropriate than RT-PCR to evaluate the efficacy of the mouthwashes.

Objectives To assess second-line antiretroviral therapy (ART) virological failure and HIV drug resistance-associated mutations (RAMs), in support of third-line regimen planning in Asia. Methods Adults > 18 years of age on second-line ART for ≥ 6 months were eligible. Cross-sectional data on HIV viral load (VL) and genotypic resistance testing were collected or testing was conducted between July 2015 and May 2017 at 12 Asia-Pacific sites. Virological failure (VF) was defined as VL > 1000 copies/mL with a second VL > 1000 copies/mL within 3-6 months. FASTA files were submitted to Stanford University HIV Drug Resistance Database and RAMs were compared against the IAS-USA 2019 mutations list. VF risk factors were analysed using logistic regression. Results Of 1378 patients, 74% were male and 70% acquired HIV through heterosexual exposure. At second-line switch, median [interquartile range (IQR)] age was 37 (32-42) years and median (IQR) CD4 count was 103 (43.5-229.5) cells/µL; 93% received regimens with boosted protease inhibitors (PIs). Median duration on second line was 3 years. Among 101 patients (7%) with VF, CD4 count > 200 cells/µL at switch [odds ratio (OR) = 0.36, 95% confidence interval (CI): 0.17-0.77 vs. CD4 ≤ 50) and HIV exposure through male-male sex (OR = 0.32, 95% CI: 0.17-0.64 vs. heterosexual) or injecting drug use (OR = 0.24, 95% CI: 0.12-0.49) were associated with reduced VF. Of 41 (41%) patients with resistance data, 80% had at least one RAM to nonnucleoside reverse transcriptase inhibitors (NNRTIs), 63% to NRTIs, and 35% to PIs. Of those with PI RAMs, 71% had two or more. Conclusions There were low proportions with VF and significant RAMs in our cohort, reflecting the durability of current second-line regimens.

Objectives We conducted a longitudinal cohort analysis to evaluate the association of pre-treatment body mass index (BMI) with CD4 recovery, virological failure (VF) and cardiovascular risk disease (CVD) markers among people living with HIV (PLHIV). Methods Participants who were enrolled between January 2003 and March 2019 in a regional Asia HIV cohort with weight and height measurements prior to antiretroviral therapy (ART) initiation were included. Factors associated with mean CD4 increase were analysed using repeated-measures linear regression. Time to first VF after 6 months on ART and time to first development of CVD risk markers were analysed using Cox regression models. Sensitivity analyses were done adjusting for Asian BMI thresholds. Results Of 4993 PLHIV (66% male), 62% had pre-treatment BMI in the normal range (18.5-25.0 kg/m2 ), while 26%, 10% and 2% were underweight ( 30 kg/m2 ), respectively. Both higher baseline and time-updated BMI were associated with larger CD4 gains compared with normal BMI. After adjusting for Asian BMI thresholds, higher baseline BMIs of 23-27.5 and > 27.5 kg/m2 were associated with larger CD4 increases of 15.6 cells/µL [95% confidence interval (CI): 2.9-28.3] and 28.8 cells/µL (95% CI: 6.6-50.9), respectively, compared with normal BMI (18.5-23 kg/m2 ). PLHIV with BMIs of 25-30 and > 30 kg/m2 were 1.27 times (95% CI: 1.10-1.47) and 1.61 times (95% CI: 1.13-2.24) more likely to develop CVD risk factors. No relationship between pre-treatment BMI and VF was observed. Conclusions High pre-treatment BMI was associated with better immune reconstitution and CVD risk factor development in an Asian PLHIV cohort.

Objective Tenofovir disoproxyl fumarate (TDF) disoproxyl fumarate (TDF) has in vitro activity against herpes simplex virus type 2 (HSV-2) and reduced HSV-2 acquisition as preexposure prophylaxis. Whether TDF-containing antiretroviral therapy (ART) reduces HSV-2 acquisition is unknown. Design Secondary analysis of AIDS Clinical Trials Group A5175, a randomized, open-label study of 3 ART regimens among 1571 participants. Methods HSV-2 serostatus was assessed at baseline, at study exit, and before a change in ART regimen. Results Of 365 HSV-2-seronegative persons, 68 acquired HSV-2, with 24 receiving TDF-containing ART and 44 receiving ART without TDF (HSV-2 seroconversion incidence, 6.42 and 6.63 cases/100 person-years, respectively; hazard ratio, 0.89; 95% confidence interval, .55-1.44). Conclusions HSV-2 acquisition was not reduced in HIV-infected, HSV-2-uninfected persons during TDF-containing ART.

PURPOSE: Antiretroviral monotherapy and treatment interruption are potential strategies for perinatally HIV-infected adolescents (PHIVA) who face challenges maintaining effective combination antiretroviral therapy (ART). We assessed the use and outcomes for adolescents receiving monotherapy or undergoing treatment interruption in a regional Asian cohort. METHODS: Regional Asian data (2001–2016) were analyzed to describe PHIVA who experienced ≥2 weeks of lamivudine or emtricitabine monotherapy or treatment interruption and trends in CD4 count and HIV viral load during and after episodes. Survival analyses were used for World Health Organization (WHO) stage III/IV clinical and immunologic event-free survival during monotherapy or treatment interruption, and a Poisson regression to determine factors associated with monotherapy or treatment interruption. RESULTS: Of 3,448 PHIVA, 84 (2.4%) experienced 94 monotherapy episodes, and 147 (4.3%) experienced 174 treatment interruptions. Monotherapy was associated with older age, HIV RNA >400 copies/mL, younger age at ART initiation, and exposure to ≥2 combination ART regimens. Treatment interruption was associated with CD4 count

It has been postulated that the direction of HIV transmission between two individuals can be determined by phylogenetic analysis of HIV sequences. This approach may be problematic, since HIV sequences from newly infected individuals are often more similar to index sequences from samples collected years before transmission, compared to those from samples collected at the time of transmission. We evaluated the accuracy of phylogenetic methods for determining the direction of HIV transmission by analyzing next-generation sequencing (NGS) data from index–partner pairs enrolled in the HIV Prevention Trials Network (HPTN) 052 trial. HIV-infected index and HIV-uninfected partner participants were enrolled as serodiscordant couples; samples were analyzed from couples with index-to-partner HIV transmission that was confirmed by genetic linkage studies. NGS for HIV gp41 (HXB2 coordinates: 7691–8374) was performed using plasma samples from thirty-nine index–partner pairs (seventy-eight samples collected within 3 months of partner seroconversion). Maximum likelihood trees were generated using the entire dataset using FastTree v.2. Topological patterns of HIV from each index–partner pair were analyzed. The analysis included 9,368 consensus sequences and 521,145 total sequence reads for the seventy-eight samples analyzed. In 10 per cent (four out of thirty-nine) of couples, the phylogeny was inconsistent with the known direction of transmission. In 26 per cent (ten out of thirty-nine) of couples, the phylogeny results could not discern directionality. In 64 per cent (twenty-five out of thirty-nine) of couples, the results correctly indicated index-to-partner transmission; in two of these twenty-five cases, only one index sequence was closest to the most recent common ancestor. Phylogenetic analysis of NGS data obtained from samples collected within 3 months of transmission correctly determined the direction of transmission in 64 per cent of the cases analyzed. In 36 per cent of the cases, the phylogenetic topology did not support the known direction of infection, and in one-third of these cases the observed topology was opposite to the known direction of transmission. This demonstrates that phylogenetic topology alone may not be sufficient to accurately determine the direction of HIV transmission.

SETTING: The household contacts (HHCs) of multidrug-resistant tuberculosis (MDR-TB) index cases are at high risk of tuberculous infection and disease progression, particularly if infected with the human immunodeficiency virus (HIV). HIV testing is important for risk assessment and clinical management. METHODS: This was a cross-sectional, multi-country study of adult MDR-TB index cases and HHCs. All adult and child HHCs were offered HIV testing if never tested or if HIV-negative >1 year previously when last tested. We measured HIV testing uptake and used logistic regression to evaluate predictors. RESULTS: A total of 1007 HHCs of 284 index cases were enrolled in eight countries. HIV status was known at enrolment for 226 (22%) HHCs; 39 (4%) were HIV-positive. HIV testing was offered to 769 (98%) of the 781 remaining HHCs; 544 (71%) agreed to testing. Of 535 who were actually tested, 26 (5%) were HIV-infected. HIV testing uptake varied by site (median 86%, range 0-100%; P

Summary Background Antiretroviral therapy (ART) management is challenging for individuals in resource-limited settings presenting for third-line treatment because of complex resistance patterns, partly due to reduced access to viral load monitoring. We aimed to evaluate use of newer antiretroviral drugs and contemporary management approaches, including population-based sequencing, to select appropriate antiretrovirals, plasma viral load monitoring, and interventions to improve adherence in individuals presenting with second-line viral failure. Methods A5288 was a phase 4, third-line ART strategy study done at 19 urban sites in ten countries that enrolled adult participants with confirmed plasma HIV-1 RNA (viral load) of 1000 copies per mL or more after more than 24 weeks of protease inhibitor-based second-line ART. The primary objective was to use antiretrovirals (raltegravir, etravirine, and ritonavir-boosted darunavir) and diagnostic monitoring technologies, including viral load, genotyping, and adherence support to achieve viral load suppression (defined as ≤200 copies per mL) in 65% or more of participants. ART history and real-time drug resistance genotypes were used to assign participants to one of four cohorts: cohort A (no lopinavir resistance) stayed on second-line ART and cohorts B (B1, best available nucleoside reverse transcriptase inhibitors [NRTIs] plus ritonavir-boosted darunavir plus raltegravir; B2, ritonavir-boosted darunavir plus raltegravir plus etravirine; B3, ritonavir-boosted darunavir, raltegravir, and either tenofovir plus emtricitabine or tenofovir plus lamivudine), C (ritonavir-boosted darunavir plus raltegravir plus tenofovir-emtricitabine or tenofovir plus lamivudine), and D (best available NRTIs plus ritonavir-boosted darunavir plus raltegravir) were defined by increasing levels of resistance and received appropriate regimens, including new antiretrovirals. Participants in Cohort B without detectable hepatitis B surface antigen were assigned by blocked randomisation to cohorts B1 and B2, and those with detectable hepatitis B surface antigen were assigned to cohort B3. The trial is registered with ClinicalTrials.gov , number NCT01641367 . Findings From Jan 10, 2013, to Sept 10, 2015, 545 participants were enrolled. 287 (53%) were assigned to cohort A, 74 (14%) to B1, 72 (13%) to B2, eight (1%) to B3, 70 (13%) to C, and 34 (6%) to D. Overall, 349 (64%, 95% CI 60–68) participants achieved viral suppression at week 48, with proportions varying from 125 (44%) of 287 in cohort A to 65 (88%) of 74 in cohort B1, 63 (88%) of 72 in B2, eight (100%) of eight in B3, 63 (90%) of 70 in C, and 25 (74%) of 34 in D. Participants in cohort A remained on their second-line protease inhibitor, and had the most participants with grade 3 or higher adverse events (147 [51%]). Interpretation Targeted real-time genotyping to select third-line ART can appropriately allocate more costly antiretrovirals to those with greater levels of HIV drug resistance.

Objectives In multisite human immunodeficiency virus (HIV) observational cohorts, clustering of observations often occurs within sites. Ignoring clustering may lead to “Simpson's paradox” (SP) where the trend observed in the aggregated data is reversed when the groups are separated. This study aimed to investigate the SP in an Asian HIV cohort and the effects of site-level adjustment through various Cox regression models. Study Design and Setting Survival time from combination antiretroviral therapy (cART) initiation was analyzed using four Cox models: (1) no site adjustment; (2) site as a fixed effect; (3) stratification through site; and (4) shared frailty on site. Results A total of 6,454 patients were included from 23 sites in Asia. SP was evident in the year of cART initiation variable. Model (1) shows the hazard ratio (HR) for years 2010–2014 was higher than the HR for 2006–2009, compared to 2003–2005 (HR = 0.68 vs. 0.61). Models (2)–(4) consistently implied greater improvement in survival for those who initiated in 2010–2014 than 2006–2009 contrasting findings from model (1). The effects of other significant covariates on survival were similar across four models. Conclusions Ignoring site can lead to SP causing reversal of treatment effects. Greater emphasis should be made to include site in survival models when possible.

Objectives The aim of the study was to assess the prevalence and characteristics associated with current smoking in an Asian HIV-positive cohort, to calculate the predictive risks of cardiovascular disease (CVD), coronary heart disease (CHD) and myocardial infarction (MI), and to identify the impact that simulated interventions may have. Methods Logistic regression analysis was used to distinguish associated current smoking characteristics. Five-year predictive risks of CVD, CHD and MI and the impact of simulated interventions were calculated utilizing the Data Collection on Adverse Effects of Anti-HIV Drugs Study (D:A:D) algorithm. Results Smoking status data were collected from 4274 participants and 1496 of these had sufficient data for simulated intervention calculations. Current smoking prevalence in these two groups was similar (23.2% vs. 19.9%, respectively). Characteristics associated with current smoking included age > 50 years compared with 30–39 years [odds ratio (OR) 0.65; 95% confidence interval (CI) 0.51–0.83], HIV exposure through injecting drug use compared with heterosexual exposure (OR 3.03; 95% CI 2.25–4.07), and receiving antiretroviral therapy (ART) at study sites in Singapore, South Korea, Malaysia, Japan and Vietnam in comparison to Thailand (all OR > 2). Women were less likely to smoke than men (OR 0.11; 95% CI 0.08–0.14). In simulated interventions, smoking cessation demonstrated the greatest impact in reducing CVD and CHD risk and closely approximated the impact of switching from abacavir to an alternate antiretroviral in the reduction of 5-year MI risk. Conclusions Multiple interventions could reduce CVD, CHD and MI risk in Asian HIV-positive patients, with smoking cessation potentially being the most influential.

Four million people of the global total of 35 million with HIV infection are from South-East Asia. ART is currently utilized by 15 million people and has led to a dramatic decline in the mortality rate, including those in low- and middle-income countries. A reduction in sexually transmitted HIV and in comorbidities including tuberculosis has also followed. Current recommendations for the initiation of antiretroviral therapy in people who are HIV+ are essentially to initiate ART irrespective of CD4 cell count and clinical stage. The frequency of HIV testing should be culturally specific and based on the HIV incidence in different key populations but phasing in viral load technology in LMIC is an urgent priority and this needs resources and capacity. With the availability of simplified potent ART regimens, persons with HIV now live longer. The recent WHO treatment guidelines recommending routine HIV testing and earlier initiation of treatment should be the stepping stone for ending the AIDS epidemic and to meet the UNAIDS mission of 90*90*90.

Purpose: Re-emergent ocular syphilis in patients with Human immunodeficiency virus (HIV) co-infection has both diagnostic and management difficulties because of the overlapping risk factors. The clinical manifestations described in non-HIV may not be the same in patients with HIV coinfection. Immune recovery uveitis (IRU) may also alter the course of the disease causing recurrences. We studied the clinical features in correlation with CD4 counts, systemic immune status, sexual preferences and management outcomes in HIV/AIDS patients with ocular syphilis in the highly active antiretroviral treatment (HAART) era from a high endemic HIV population like India. Methods: Retrospective analysis of all patients with ocular syphilis and HIV/AIDS seen between 2016 and 2019 was done. Results: A total of 33 patients (56 eyes) with a CD4 count range of 42–612 cells/cu.mm were included. Ocular syphilis was found to be higher in individuals with high risk behavior such as men who have sex with men (MSMs) (45%). Panuveitis was the commonest manifestation (53.57%) and was even the presenting feature of HIV and syphilis in many patients. Significant vitritis, usually uncommon in HIV/AIDS immunocompromised patients was noted even with low CD4 counts in patients with ocular syphilis. Significant correlation was noted between ocular presentation and CD4 counts (P < 0.05). Conclusion: Ocular syphilis presents differently in patients with HIV/AIDS. Diffuse retinitis is seen commonly in low counts (400 cells/cu.mm). Ocular manifestations can be an indicator of the immune status of the patient. Not all patients with ocular manifestations have associated features of systemic syphilis. Ocular manifestations can be the first presentation of HIV/AIDS. Although, there is good response to systemic penicillin and HAART, recurrences and immune recovery uveitis (IRU) can also occur.

OBJECTIVES With aging of the HIV-positive population, cardiovascular disease (CVD) increasingly contributes to morbidity and mortality. We investigated CVD-related and other causes of death (CODs) and factors associated with CVD in a multi-country Asian HIV-positive cohort. METHODS Patient data from 2003-2017 were obtained from the Therapeutics, Research, Education and AIDS Training in Asia (TREAT Asia) HIV Observational Database (TAHOD). We included patients on antiretroviral therapy (ART) with > 1 day of follow-up. Cumulative incidences were plotted for CVD-related, AIDS-related, non-AIDS-related, and unknown CODs, and any CVD (i.e. fatal and nonfatal). Competing risk regression was used to assess risk factors of any CVD. RESULTS Of 8069 patients with a median follow-up of 7.3 years [interquartile range (IQR) 4.4-10.7 years], 378 patients died [incidence rate (IR) 6.2 per 1000 person-years (PY)], and this total included 22 CVD-related deaths (IR 0.36 per 1000 PY). Factors significantly associated with any CVD event (IR 2.2 per 1000 PY) were older age [sub-hazard ratio (sHR) 2.21; 95% confidence interval (CI) 1.36-3.58 for age 41-50 years; sHR 5.52; 95% CI 3.43-8.91 for ≥ 51 years, compared with < 40 years], high blood pressure (sHR 1.62; 95% CI 1.04-2.52), high total cholesterol (sHR 1.89; 95% CI 1.27-2.82), high triglycerides (sHR 1.55; 95% CI 1.02-2.37) and high body mass index (BMI) (sHR 1.66; 95% CI 1.12-2.46). CVD crude IRs were lower in the later ART initiation period and in lower middle- and upper middle-income countries. CONCLUSIONS The development of fatal and nonfatal CVD events in our cohort was associated with older age, and treatable risk factors such as high blood pressure, triglycerides, total cholesterol and BMI. Lower CVD event rates in middle-income countries may indicate under-diagnosis of CVD in Asian-Pacific resource-limited settings.

BACKGROUND: Current guidelines recommend evaluation of household contacts (HHC) of individuals with multidrug-resistant tuberculosis (MDR-TB) but widespread implementation of this policy is challenging. OBJECTIVE: To describe site-level resource utilization and operational challenges encountered when identifying, recruiting, and characterizing adult MDR-TB Index Cases and their HHC. DESIGN: Cross-sectional study of adult MDR-TB Index Cases and HHC at 16 clinical research sites in 8 countries. Site-level resource utilization was assessed using structured surveys. RESULTS: Between October 2015 and April 2016, 308 Index Cases and 1018 HHC were enrolled. Of 280 Index Cases with sputum collected, 94 were smear positive (34%, 95% Confidence Interval (CI): 28–39%) and of 201 with chest x-rays, 87 had cavitary disease (43%, CI: 37–50%) after a mean duration of treatment of 8 weeks. Staff required 512 attempts to evaluate the 308 households, median time per attempt of 4 hours. 77% (CI: 73─80%) of the HHC were at increased risk for TB: 13% < 5 years; 8% >5 years. and HIV-infected; and 79% >5 years, HIV-/unknown and TST/IGRA positive. 121 previously undiagnosed TB cases were identified. Issues identified by site staff included complexity of personnel and participant transportation, infection control, personnel safety and management of stigma surrounding household visits. CONCLUSION: Household contact investigations can be high yield but are labor intensive.

For more than two decades, CD4 cell count measurements have been central to understanding HIV disease progression, making important clinical decisions, and monitoring the response to antiretroviral therapy (ART). In well resourced settings, the monitoring of patients on ART has been supported by routine virological monitoring. Viral load monitoring was recommended by WHO in 2013 guidelines as the preferred way to monitor people on ART, and efforts are underway to scale up access in resource-limited settings. Recent studies suggest that in situations where viral load is available and patients are virologically suppressed, long-term CD4 monitoring adds little value and stopping CD4 monitoring will have major cost savings. CD4 cell counts will continue to play an important part in initial decisions around ART initiation and clinical management, particularly for patients presenting late to care, and for treatment monitoring where viral load monitoring is restricted. However, in settings where both CD4 cell counts and viral load testing are routinely available, countries should consider reducing the frequency of CD4 cell counts or not doing routine CD4 monitoring for patients who are stable on ART.

In India, potato is a major vegetable crop. India exported about 114,245 t of potato to Nepal, Sri Lanka, Pakistan, Mauritius and Bangladesh (2012-13).For the study, secondary data were used. The collected data were analyzed using compound growth rate, instability index, Markov chain analysis and Nominal Protection Co-efficient (NPC). It was found that during 1990-2013, the growth rate of both fresh and frozen potatoes was positive and instability in the value of fresh and frozen potato export was high. The Markov chain analysis showed that Nepal and ‘other countries’ were the stable importers of fresh and frozen potatoes from India and it retained its original share of about 66 per cent and 94 per cent, respectively(2001-2011). The NPC results showed that fresh potatoes were price competitive in the international markets and have greater potential for expansion of the domestic industry in the years to come.

Purpose of review The generic antiretroviral (ARV) industry played a critical role in the massive scale-up of HIV treatment in low-income and middle-income countries since 2000. As the global community looks ahead to a universal antiretroviral regimen, this article considers the industry's role in supporting universal access to affordable, simpler, more durable, and tolerable HIV treatment regimens. Recent findings Generic manufacturers made treatment scale-up in low-income and middle-income countries possible through reducing prices, combining molecules from different originator companies to develop optimal fixed-dose combinations, and investing in production capacity to meet escalating demand. Achieving scale-up of a universal regimen will require continued partnership in these areas. Collaboration on the demand and supply sides of the ARV marketplace will be required to foster a healthy and sustainable marketplace for new regimens. This includes clear priority setting from the global treatment community on priority products; predictable demand; regulatory prioritization of optimal products; effective tendering and procurement practices that enable multiple suppliers to participate in the market; coordinated product introduction efforts between Ministries of Health, partners, and civil society; and transparency from both buyers and suppliers to promote and monitor supply security. Summary New regimens will benefit people living with HIV, as well as buyers and generic suppliers, by maximizing existing production capacity and treatment budgets to reach the 90-90-90 goals.

Bangladesh remains a low prevalence country for HIV infection. In this article we attempt to address the reasons for the present success in this country and the challenges lying ahead to minimise the spread of HIV in the future.

Summary Background Use of antiretroviral treatment for HIV-1 infection has decreased AIDS-related morbidity and mortality and prevents sexual transmission of HIV-1. H owever, the best time to initiate antiretroviral treatment to reduce progression of HIV-1 infection or non-AIDS clinical events is unknown. We reported previously that early antiretroviral treatment reduced HIV-1 transmission by 96%. We aimed to compare the eff ects of early and delayed initiation of antiretroviral treatment on clinical outcomes. Methods The HPTN 052 trial is a randomised controlled trial done at 13 sites in nine countries. We enrolled HIV-1-serodiscordant couples to the study and randomly allocated them to either early or delayed antiretroviral treatment by use of permuted block randomisation, stratifi ed by site. Random assignment was unblinded. The HIV-1-infected member of every couple initiated antiretroviral treatment either on entry into the study (early treatment group) or after a decline in CD4 count or with onset of an AIDS-related illness (delayed treatment group). Primary events were AIDS clinical events (WHO stage 4 HIV-1 disease, tuberculosis, and severe bacterial infections) and the following serious medical conditions unrelated to AIDS: serious cardiovascular or vascular disease, serious liver disease, end-stage renal disease, new-onset diabetes mellitus, and non-AIDS malignant disease. Analysis was by intention-to-treat. This trial is registered with ClinicalTrials.gov, number NCT00074581. Findings 1763 people with HIV-1 infection and a serodiscordant partner were enrolled in the study; 886 were assigned early antiretroviral treatment and 877 to the delayed treatment group (two individuals were excluded from this group af ter randomisation). Median CD4 counts at randomisation were 442 (IQR 373–522) cells per μL in patients assigned to the early treatment group and 428 (357–522) cells per μL in those allocated delayed antiretroviral treatment. In the delayed group, antiretroviral treatment was initiated at a median CD4 count of 230 (IQR 197–249) cells per μL. Primary clinical events were reported in 57 individuals assigned to early treatment initiation versus 77 people allocated to delayed antiretroviral treatment (hazard ratio 0·73, 95% CI 0·52–1·03; p=0·074). New-onset AIDS events were recorded in 40 participants assigned to early antiretroviral treatment versus 61 allocated delayed initiation (0·64, 0·43–0·96; p=0·031), tuberculosis developed in 17 versus 34 patients, respectively (0·49, 0·28–0·89, p=0·018), and primary nonAIDS events were rare (12 in the early group vs nine with delayed treatment). In total, 498 primary and secondary outcomes occurred in the early treatment group (incidence 24·9 per 100 person-years, 95% CI 22·5–27·5) versus 585 in the delayed treatment group (29·2 per 100 person-years, 26·5–32·1; p=0·025). 26 people died, 11 who were allocated to early antiretroviral treatment and 15 who were assigned to the delayed treatment group.

BACKGROUND The burden of Kaposi sarcoma (KS) in human immunodeficiency virus (HIV)-infected children and adolescents on combination antiretroviral therapy (cART) has not been compared globally. METHODS We analyzed cohort data from the International Epidemiologic Databases to Evaluate AIDS and the Collaboration of Observational HIV Epidemiological Research in Europe. We included HIV-infected children aged

Objective. Nevirapine is metabolized by cytochrome P450 (CYP) 2B6 and CYP3A4. We characterized relationships between clinical parameters, human genetics, pharmacokinetics, and human immunodeficiency virus type 1 (HIV-1) drug resistance mutations in pregnant women following single-dose intrapartum nevirapine. Methods. In AIDS Clinical Trials Group study A5207, women received nevirapine at onset of labor and were randomly assigned to receive lamivudine/zidovudine, emtricitabine/tenofovir, or lopinavir/ritonavir for 7 or 21 days. Plasma nevirapine level was quantified on postpartum day 1 and on weeks 1, 3, and 5. We assayed 214 polymorphisms in CYP2B6 and other genes and evaluated associations with pharmacokinetic parameters, including elimination constant, time to protein-adjusted 50% inhibitory concentration (IC50), and week 5 nevirapine level below the quantification limit. Results. Among 301 women with evaluable pharmacokinetic and genotype data, lower body mass index and random assignment to receive lopinavir/ritonavir were associated with more rapid nevirapine elimination. Among those of African ancestry, longer time to IC50 was associated with CYP2B6 983T→C (P = .004) but not with CYP2B6 516G→T (P = .8). Among Indians, slower nevirapine elimination was associated with CYP2B6 516G→T (P = .04). Emergent resistance was infrequent and not associated with pharmacokinetics or CYP2B6 genotype. Conclusions. The effects on plasma drug exposure following single-dose nevirapine may be greater for CYP2B6 983T→C than for 516G→T and are less pronounced than at steady state.

Background. Combination antiretroviral therapy (cART) reduces genital tract human immunodeficiency virus type 1 (HIV-1) load and reduces the risk of sexual transmission, but little is known about the efficacy of cART for decreasing genital tract viral load (GTVL) and differences in sex or HIV-1 subtype. Methods. HIV-1 RNA from blood plasma, seminal plasma, or cervical wicks was quantified at baseline and at weeks 48 and 96 after entry in a randomized clinical trial of 3 cART regimens. Results. One hundred fifty-eight men and 170 women from 7 countries were studied (men: 55% subtype B and 45% subtype C; women: 24% subtype B and 76% subtype C). Despite similar baseline CD4+ cell counts and blood plasma viral loads, women with subtype C had the highest GTVL (median, 5.1 log10 copies/mL) compared to women with subtype B and men with subtype C or B (4.0, 4.0, and 3.8 log10 copies/mL, respectively; P < .001). The proportion of participants with a GTVL below the lower limit of quantification (LLQ) at week 48 (90%) and week 96 (90%) was increased compared to baseline (16%; P < .001 at both times). Women were significantly less likely to have GTVL below the LLQ compared to men (84% vs 94% at week 48, P = .006; 84% vs 97% at week 96, P = .002), despite a more sensitive assay for seminal plasma than for cervical wicks. No difference in GTVL response across the 3 cART regimens was detected. Conclusions. The female genital tract may serve as a reservoir of persistent HIV-1 replication during cART and affect the use of cART to prevent sexual and perinatal transmission of HIV-1.

Introduction: We determine the frequency and immunological outcome of developing immune reconstitution inflammatory syndrome (IRIS) among HIV/tuberculosis (TB)–coinfected Indians receiving highly active antiretroviral therapy (HAART). Methods: Patients coinfected with TB and HIV who initiated HAART were classified based on treatment outcomes (IRIS and non-IRIS) utilizing an observational HIV/AIDS cohort. Results: A total of 1731 HIV/TB-coinfected patients initiated HAART, and 95 of these patients (5.5%) developed TB-IRIS, with an incidence rate of 0.26 per 100 person-years. Patients who developed IRIS had significantly higher CD4 counts than non-IRIS patients at the time of initiating HAART, as well as after 6 months, 18 months, and 24 months following HAART initiation ( P < .05). Conclusions: HIV/TB-coinfected patients who developed IRIS following HAART initiation had equivalent clinical outcomes compared with their HIV/TB-coinfected counterparts who did not develop IRIS, suggesting minimal long-term risks associated with IRIS.

Antiretroviral therapy (ART) is indicated during tuberculosis treatment in patients infected with human immunodeficiency virus type 1 (HIV-1), but the timing for the initiation of ART when tuberculosis is diagnosed in patients with various levels of immune compromise is not known.We conducted an open-label, randomized study comparing earlier ART (within 2 weeks after the initiation of treatment for tuberculosis) with later ART (between 8 and 12 weeks after the initiation of treatment for tuberculosis) in HIV-1 infected patients with CD4+ T-cell counts of less than 250 per cubic millimeter and suspected tuberculosis. The primary end point was the proportion of patients who survived and did not have a new (previously undiagnosed) acquired immunodeficiency syndrome (AIDS)-defining illness at 48 weeks.A total of 809 patients with a median baseline CD4+ T-cell count of 77 per cubic millimeter and an HIV-1 RNA level of 5.43 log(10) copies per milliliter were enrolled. In the earlier-ART group, 12.9% of patients had a new AIDS-defining illness or died by 48 weeks, as compared with 16.1% in the later-ART group (95% confidence interval [CI], -1.8 to 8.1; P=0.45). Among patients with screening CD4+ T-cell counts of less than 50 per cubic millimeter, 15.5% of patients in the earlier-ART group versus 26.6% in the later-ART group had a new AIDS-defining illness or died (95% CI, 1.5 to 20.5; P=0.02). Tuberculosis-associated immune reconstitution inflammatory syndrome was more common with earlier ART than with later ART (11% vs. 5%, P=0.002). The rate of viral suppression at 48 weeks was 74% and did not differ between the groups (P=0.38).Overall, earlier ART did not reduce the rate of new AIDS-defining illness and death, as compared with later ART. In persons with CD4+ T-cell counts of less than 50 per cubic millimeter, earlier ART was associated with a lower rate of new AIDS-defining illnesses and death.

Introduction: We describe the safety tolerability and efficacy of protease inhibitor (PI) containing highly active antiretroviral therapy (HAART) among patients switching from nonnucleoside reverse transcriptase inhibitor (NNRTI)-based HAART from a clinical setting in South India. Methods: We assessed a prospective cohort of 91 HIV-infected patients with at least 12 months of clinical follow-up on second-line ritonavir-boosted PI-based therapy between August 2003 and December 2008. Results: More than three fourths of patients met the World Health Organization (WHO) criteria for immunological failure at the time of switch. The median time to switch was 758 days. Patients demonstrated consistent increases in their CD4 counts during the first 12 months by which time the median CD4 count was 322 cells/mm3. The most common adverse events within the first year after switch were nausea (14.8%) lipodystrophy (10.4%) and peripheral neuropathy (7.0%). Patients switching to atazanavir (ATV)-based regimens compared to those switching to indinavir (IDV)-based regimens had similar immunological and clinical outcomes. Conclusions: Given the therapeutic success of using second-line PI-containing HAART after experiencing treatment failure further efforts must be taken to expand access to second-line HAART so that more patients can benefit from these drugs.
