Noncholera vibriosis is a rare, opportunistic bacterial infection caused by Vibrio spp. other than V. cholerae O1/O139 and diagnosed mainly during the hot summer months in patients after seaside activities. Detailed knowledge of circulating pathogenic strains and heterogeneities in infection outcomes and disease dynamics may help in patient management. We conducted a multicenter case-series study documenting Vibrio infections in 67 patients from 8 hospitals in the Bay of Biscay, France, over a 19-year period. Infections were mainly caused by V. alginolyticus (34%), V. parahaemolyticus (30%), non-O1/O139 V. cholerae (15%), and V. vulnificus (10%). Drug-susceptibility testing revealed intermediate and resistant strains to penicillins and first-generation cephalosporins. The acute infections (e.g., those involving digestive disorder, cellulitis, osteitis, pneumonia, and endocarditis) led to a life-threatening event (septic shock), amputation, or death in 36% of patients. Physicians may need to add vibriosis to their list of infections to assess in patients with associated risk factors. [ABSTRACT FROM AUTHOR]

Background We investigated whether dolutegravir (DTG) monotherapy could be used to maintain virological suppression in people living with human immunodeficiency virus (HIV) on a successful dolutegravir-based triple therapy. Methods MONCAY (MONotherapy of TiviCAY) was a 48-week, multicentric, randomized, open-label, 12% noninferiority margin trial. Patients with CD4 nadir >100/μL, plasma HIV-1 RNA <50 copies/mL for ≥12 months, and stable regimen with DTG/abacavir (ABC)/lamivudine (3TC) were 1:1 randomized to continue their regimen or to DTG monotherapy. The primary endpoint was the proportion of patients with HIV RNA <50 copies/mL at week 24 in intention-to-treat snapshot analysis. Virologic failure (VF) was defined as 2 consecutive HIV RNA >50 copies/mL within 2 weeks apart. Results Seventy-eight patients were assigned to DTG monotherapy and 80 to continue DTG/ABC/3TC. By week 24, 2 patients in the DTG group experienced VF without resistance to the integrase strand transfer inhibitor (INSTI) class; 1 patient discontinued DTG/ABC/3TC due to an adverse event. The success rate at week 24 was 73/78 (93.6%) in the DTG arm and 77/80 (96.3%) in the DTG/ABC/3TC arm (difference, 2.7%; 95% confidence interval [CI], –5.0 to 10.8). During subsequent follow-up, 5 additional VFs occurred in the DTG arm (2 of which harbored emerging resistance mutation to INSTI). The cumulative incidence of VF at week 48 was 9.7% (95% CI, 2.8 to 16.6) in the DTG arm compared with 0% in the DTG/ABC/3TC arm (P =.005 by the log-rank test). The Data Safety Monitoring Board recommended to reintensify the DTG arm with standardized triple therapy. Conclusions Because the risk of VF with resistance increases over time, we recommend avoiding DTG monotherapy as a maintenance strategy among people living with chronic HIV infection.

Essential HIV cure-related clinical trials (HCRCT) have a potentially high-risk profile in terms of participants’ health, which could hinder enrollment by people living with HIV (PLWH) and healthcare professionals (HP). The ANRS-APSEC survey is part of the IAS “Towards an HIV cure” initiative, which promotes multidisciplinary research for a safe, affordable and scalable cure. The study objectives were to understand the psychosocial mechanisms underlying PLWH and HP viewpoints about future HCRCT. Six focus group discussions (three with PLWH (n = 21) and three with HP (n = 30)) were held in three French infectious disease units. From these, three perspectives on HCRCT were identified. The first involved beliefs and knowledge associating HCRCT with poorer health and quality of life for PLWH. The second concerned perceptions of HCRCT as a biological and epidemiological flashback to a situation when HIV infection was left uncontrolled. The third was characterized by aspects of historical HIV culture that embrace innovation. [ABSTRACT FROM AUTHOR]

Purpose: To identify HIV clinicians' needs for the clinical use of a new patient-reported outcome measure (PRO) on barriers to antiretroviral therapy (ART) adherence.Methods: In 2015, five focus groups with 31 clinicians from France were transcribed, coded with Atlas.ti, and submitted to a typological analysis.Results: The analysis identified seven patient profiles, each tied to distinct barriers to adherence and to specific needs for the PRO's content, data collection and transmission. Clinicians preferred, for the patient who is: (1) 'passive,' that the PRO collect information on ART knowledge, to ensure that the prescription's instructions are being respected; (2) 'misleading,' that it be able to detect adherence to ART and socially desirable responses; (3) 'stoic,' that questions challenge the patient to recognize treatment-specific side effects; (4) 'hedonistic,' that the PRO contains content on lifestyle and risk-taking; (5) 'obsessive,' that the PRO captures quality of life and stressful life events; (6) 'overburdened,' that the PRO provides information on the person's home environment, socioeconomic status and cultural constraints. For all or most patient profiles, the clinicians wished that the PRO be completed, minimally, prior to the medical consultation and to receive alerts, under varying conditions, when problematic scores were detected. Depending on the profile, there was preference for the inclusion of open-ended questions and transmission of cross-sectional, periodic or longitudinal PRO data.Conclusion: Overall, this study's findings suggest that to support the clinical management of ART adherence, our PRO must meet the needs of a wide variety of patients and must perform multiple functions.

Objectives: We investigated the risk of virological rebound in HIV-1-infected patients achieving virological suppression on first-line combined ART (cART) according to baseline HIV-1 RNA, time to virological suppression and type of regimen.Patients and Methods: Subjects were 10 836 adults who initiated first-line cART (two nucleoside or nucleotide reverse transcriptase inhibitors + efavirenz, a ritonavir-boosted protease inhibitor or an integrase inhibitor) from 1 January 2007 to 31 December 2014. Cox proportional hazards models with multiple adjustment and propensity score matching were used to investigate the effect of baseline HIV-1 RNA and time to virological suppression on the occurrence of virological rebound.Results: During 411 436 patient-months of follow-up, risk of virological rebound was higher in patients with baseline HIV-1 RNA ≥100 000 copies/mL versus <100 000 copies/mL, in those achieving virological suppression in > 6 months versus <6 months, and lower with efavirenz or integrase inhibitors than with ritonavir-boosted protease inhibitors. Baseline HIV-1 RNA >100 000 copies/mL was associated with virological rebound for ritonavir-boosted protease inhibitors but not for efavirenz or integrase inhibitors. Time to virological suppression >6 months was strongly associated with virological rebound for all regimens.Conclusions: In HIV-1-infected patients starting cART, risk of virological rebound was lower with efavirenz or integrase inhibitors than with ritonavir-boosted protease inhibitors. These data, from a very large observational cohort, in addition to the more rapid initial virological suppression obtained with integrase inhibitors, reinforce the positioning of this class as the preferred one for first-line therapy.

Context: Despite huge advances in the fight against HIV concerning diagnosis, clinical efficacy of antiretroviral treatments (ART), patient survival and quality of life, there is still no cure. Recent developments in HIV cure research have opened the way for clinical trials which could lead to a temporary or definitive end to ART. However, ethical questions exist about related trial-participation risks. The main goal of the ANRS-APSEC survey was, using Q-methodology, to investigate the viewpoints of people living with HIV (PLWH) and HIV healthcare providers (HHP) regarding motivations for and barriers to participation in HIV Cure-related clinical trials (HCRCT). Materials and methods: Thirty-three statements were defined encompassing seven dimensions: treatment and follow-up; risks; benefits; patient-physician relationship; beliefs and attitudes; information; target population. Forty-one PLWH and 41 HHP from five French HIV services were asked to rank-order the statements. Results: Five main viewpoints were elicited from “the most motivated” to “the most reluctant” vis-à-vis HCRCT participation. All placed importance on the wish to participate in HIV research. This result is in line with the HIV-specific culture of joint mobilization. For some viewpoints, the motivation to participate in/propose HCRCT was primarily conditioned by side-effects and/or by constraints, which overall were more accepted by PLWH than HHP. Some viewpoints placed particular importance on HCRCT recruitment strategies. Finally, some expressed a high acceptance of risks and constraints but emphasized the need for information. Conclusion: HIV cure research clinical trials (HCRCT) constitute a risky yet unavoidable step towards the goal of finding a cure. To improve future HCRCT and informed consent designs, based on PLWH and HHP preferences and expectations, we need greater knowledge about how these populations perceive the risks and the benefits of HCRCT. Our results confirmed the importance of careful, studied HCRCT design, management and communication, to ensure PLWH and HHP acceptability and convergence of their expectations.

Objective: We assessed the virological efficacy of a 6 month maraviroc/raltegravir simplification strategy following 6 months of quadruple therapy combining tenofovir disoproxil fumarate/emtricitabine with maraviroc/raltegravir.Methods: HIV-1-infected naive patients were enrolled in an open label, single-arm, Phase 2 trial. All patients received maraviroc 300 mg twice daily, raltegravir 400 mg twice daily and tenofovir/emtricitabine for 24 weeks. Patients with stable HIV-RNA <50 copies/mL stopped tenofovir/emtricitabine at week (W) 24 and pursued maraviroc/raltegravir until W48. The primary endpoint was the virological response defined by HIV-RNA <50 copies/mL at W48.Results: Thirty-three patients were analysed. Patients were mostly male (94%), Caucasians (91%), MSM (82%); their median age was 42 years. At baseline, median CD4 cell count was 453 cells/mm3 and HIV-RNA was 4.3 log copies/mL. All patients had CCR5-tropic viruses by genotropism and phenotropism assays. All but one patient had an HIV-RNA < 50 copies/mL at W24 and entered the simplification phase. Virological success was maintained at W48 in 88% (90% CI 79%-97%) of patients. N155H mutation was detected at failure in one patient. No tropism switch was observed. Raltegravir and maraviroc plasma exposure were satisfactory in 92% and 79% of 41 samples from 21 patients. Five severe adverse events (SAEs) were observed up to W48; none was related to the study drugs. Four patients presented grade 3 AEs; none was related to the study. No grade 4 AE was observed. No patient died.Conclusions: Maraviroc/raltegravir maintenance therapy following a 6 month induction phase with maraviroc/raltegravir/tenofovir/emtricitabine was well tolerated and maintained virological efficacy in these carefully selected patients.

Objectives: The objective of this analysis is to perform an indirect comparison of elvitegravir, cobicistat, emtricitabine and tenofovir DF (E/C/F/TDF) to abacavir/lamivudine and dolutegravir (ABC/3TC + DTG) by using 2 trials evaluating each of these regimens in comparison to efavirenz, emtricitabine and tenofovir DF (EFV/FTC/TDF). Methods: An indirect comparison was performed by using a generalization of Bucher's methodology to calculate risk differences. Two phase III clinical trials (GS-US-236-0102 and SINGLE—described above) were used. Results: Results of the indirect comparison showed no statistically significant risk difference of the efficacy endpoint of achieving HIV RNA < 50 copies/mL between E/C/F/TDF and ABC/3TC + DTG for the ITT population at weeks 48, 96 and 144: respectively -3.7% (CI95% = [-10.8%; 3.4%]), -5.2% (CI95% = [-13.2%; 2.8%]) and -3.1% (CI95% = [-12.0%; 5.7%]). There was no statistically significant differences in the risk difference for serious adverse events (5.7% (CI95% = [-2.2%; 12.3%])), drug related adverse event (2.7% (CI95% = [-7.0%;12.4%])), drug related serious adverse event (0.8% (CI95% = [-1.6%;3.2%])) and death (0.5% (CI95% = [-0.8%;1.8%])), respectively, between E/C/F/TDF and ABC/3TC + DTG. A significant difference was found for discontinuation due to adverse events with a higher rate for E/C/F/TDF (difference = 8.6% (CI95% = [3.3%; 13.9%])). There was also no statistically significant risk difference of the viral resistance of 1.2% (CI95% = [-1.2; 3.7]) between E/C/F/TDF and ABC/3TC + DTG at week 48, 1.7% at week 96 (CI95% = [-1.1; 4.5]) and 2.2% (CI95% = [-1.0; 5.4]) at week 144.

ObjectivesEtravirine (ETR) was approved in France in September 2008 and is used in combination with a boosted protease inhibitor (bPI) and other anti-retrovirals (ART) in HIV-infected pre-treated patients. This study aimed to report in a real-life setting the efficacy and tolerability of ETR-based regimens and factors associated with virological response.MethodsThe study population included all treatment-experienced patients who initiated an ETR-based regimen between September 2008 and July 2013 from the French Dat’AIDS cohort. Analyses were performed in ART-experienced patients starting ETR after virological failure (VF) or as a maintenance therapy (MT), with or without bPI.ResultsA total of 2006 patients (VF,n = 1014 (51%); MT,n = 992 (49%)) were included. At M12, the proportion of patients with HIV RNA < 50 copies/ml was 71.7% (72.0% and 71.1% with or without bPI) in the VF group and 90.5% (85.0% and 92.3% with or without bPI) in the MT group, without significant differences regarding the use of bPI. ETR was discontinued in 8.8% of patients for adverse events in 23.9% of cases (21.5% in VF, 29.5% in MT), treatment failure in 15.2% (16.2% in VF, 7.4% in MT) or simplification in 5.4% (4.6% in VF, 7.4% in MT). In the VF group, factors associated with virological response were a longer duration of HIV infection (OR = 2.7;p < 0.001) and baseline HIV RNA < 5 log10copies/mL (OR = 2.1;p = 0.002).ConclusionThis study shows that in ART-experienced patients ETR is well tolerated with a high efficacy when combined with other active drugs, even when the regimen does not include a bPI.

Objectives: To compare adherence and persistence (continuous treatment with a prescribed medication) in HIV adult patients who received combination ART (cART) as a once-daily single-tablet regimen (STR) versus other administration schedules. Methods: A representative random sample of the French National Healthcare Insurance Database was used. Adherence and persistence were compared according to their administration schedules using χ2 and survival analyses. STRs were marketed in France in 2009 and the study period was selected to allow a sufficient number of patients with an STR and a relevant duration of follow-up. Results: During the period covered (2006-11), 362 HIV-positive adult antiretroviral-naive patients (566 lines of treatments) were selected. The mean rates of adherence were 89.6% for the STR (tenofovir/emtricitabine/efavirenz; n=76), 86.4% for cART with >1 pill once daily (n=242) and 77.0% for cART with >1 daily intake (n=248; P<0.0001 versus STR). Kaplan-Meier estimations of persistence after 2 years of treatment were 79.1% for the STR, 53.3% for cART with >1 pill once daily and 51.8% for cART with >1 daily intake (P=0.001; log-rank test). Sensitivity analyses confirmed these results. After excluding treatment sequences showing a switch from tenofovir/emtricitabine plus efavirenz to the similar STR, the rates of persistence were 80.3% for the STR (n=60), 77.3% for atazanavir-containing cART (n=96) and 68.3% for darunavir-containing cART (n=56) at 18 months (global P=0.006). Conclusions: These results suggest that persistence is higher in HIV patients treated with an STR compared with other administration schedules. Significant benefit in terms of adherence was observed with the STR in comparison with regimens with >1 daily intake but no difference was observed when comparing with regimens involving >1 pill once daily.

Background: Standard first-line antiretroviral therapy for HIV-1 infection includes two nucleoside or nucleotide reverse transcriptase inhibitors (NtRTIs), but these drugs have limitations. We assessed the 96 week efficacy and safety of an NtRTI-sparing regimen. Methods: Between August, 2010, and September, 2011, we enrolled treatment-naive adults into this randomised, open-label, non-inferiority trial in treatment-naive adults in 15 European countries. The composite primary outcome was change to randomised treatment before week 32 because of insufficient virological response, no virological response by week 32, HIV-1 RNA concentration 50 copies per mL or higher at any time after week 32; death from any cause; any new or recurrent AIDS event; or any serious non-AIDS event. Patients were randomised in a 1:1 ratio to receive oral treatment with 400 mg raltegravir twice daily plus 800 mg darunavir and 100 mg ritonavir once daily (NtRTI-sparing regimen) or tenofovir-emtricitabine in a 245 mg and 200 mg fixed-dose combination once daily, plus 800 mg darunavir and 100 mg ritonavir once daily (standard regimen). This trial was registered with ClinicalTrials.gov, number NCT01066962. Findings: Of 805 patients enrolled, 401 received the NtRTI-sparing regimen and 404 the standard regimen, with median follow-up of 123 weeks (IQR 112-133). Treatment failure was seen in 77 (19%) in the NtRTI-sparing group and 61 (15%) in the standard group. Kaplan-Meier estimated proportions of treatment failure by week 96 were 17•8% and 13•8%, respectively (difference 4•0%, 95% Cl -0•8 to 8•8). The frequency of serious or treatment-modifying adverse events were similar (10•2 vs 8•3 per 100 person-years and 3•9 vs 4•2 per 100 person-years, respectively). Interpretation: Our NtRTI-sparing regimen was non-inferior to standard treatment and represents a treatment option for patients with CD4 cell counts higher than 200 cells per µL.

Background: In highly antiretroviral-experienced patients with a multidrug-resistant human immunodeficiency virus (HIV) infection, recommended regimens should preferentially contain 3 active components, including a ritonavir-boosted protease inhibitor (PI/r). Tipranavir/r (TPV/r), a non-peptidic PI, has been specifically developed for patients resistant to the usual antiretroviral classes including PIs. This paper discusses the role of TPV/r in patients experiencing multiple PI resistance. Methods: Virological, immunological, and safety outcomes were collected between 2003 and 2007 at 7 clinical units. Virus resistance assessment was based on 3 different genotypic tests. The 207 patients evaluated had previously received nucleoside reverse transcriptase inhibitors (NRTIs) and PIs. Results: The main drugs co-administered with TPV/r were 1 or 2 NRTIs associated, in half of the patients, with enfuvirtide. After 12 weeks, viral load was <50 copies/ml in 38% of the patients (44% with enfuvirtide), while median CD4 counts had increased from 150 to 250 cells/mm3. Genotypic testing suggested that most of the patients had viruses susceptible to TPV. Lipid and transaminase levels were slightly modified, and less than 10% of treatment discontinuations were due to gastrointestinal events. Conclusion: A regimen including TPV/r associated with at least 1 active component is a valuable option in highly ARV-experienced patients with multi-resistance to the usual ARV classes including PIs.

Virological failure on a boosted-protease inhibitor (PI/r) first-line triple combination is usually not associated with the detection of resistance mutations in the protease gene. Thus, other resistance pathways are being investigated. First-line PI/ r monotherapy is the best model to investigate in vivo if the presence of mutations in the cleavage sites (CS) of gag gene prior to any antiretroviral treatment might influence PI/r efficacy. 83 patients were assigned to initiate antiretroviral treatment with first-line lopinavir/r monotherapy in the randomised Monark trial. We compared baseline sequence of gag CS between patients harbouring B or non-B HIV-1 subtype, and between those who achieved viral suppression and those who experienced virological failure while on LPV/r monotherapy up to Week 96. Baseline sequence of gag CS was available for 82/83 isolates; 81/82 carried at least one substitution in gag CS compared to HXB2 sequence. At baseline, non-B subtype isolates were significantly more likely to harbour mutations in gag CS than B subtype isolates (p,0.0001). Twenty-three patients experienced virological failure while on lopinavir/r monotherapy. The presence of more than two substitutions in p2/NC site at baseline significantly predicted virological failure (p = 0.0479), non-B subtype isolates being more likely to harbour more than two substitutions in this specific site. In conclusion, gag cleavage site was highly polymorphic in antiretroviral-naive patients harbouring a non-B HIV-1 strain. We show that pre-therapy mutations in gag cleavage site sequence were significantly associated with the virological outcome of a first-line LPV/r single drug regimen in the Monark trial.

Background. Among patients with multidrug-resistant human immunodeficiency virus type 1 (HIV-1) infection, salvage regimens including enfuvirtide have demonstrated sustained efficacy. Because of reluctance to use subcutaneous injections, raltegravir may be an alternative to replace enfuvirtide within a suppressive regimen. We conducted a prospective, randomized, open-label trial to compare the antiviral efficacy and safety of a switch to raltegravir with the efficacy and safety of continuing enfuvirtide. Methods. A total of 170 patients with multidrug-resistant HIV-1 infection and plasma HIV-1 RNA levels <400 copies/mL who were receiving enfuvirtide-based regimens were randomized 1:1 to maintain enfuvirtide or to switch to raltegravir. The primary efficacy end point was the cumulative proportion of patients with virologic failure, defined as a confirmed plasma HIV-1 RNA level ≥400 copies/mL, over 24 weeks. The secondary end points mainly involved safety. Results. The switch to raltegravir was non-inferior to the maintenance of enfuvirtide, with virologic failure rates of 1.2% in both treatment arms in the intention-to-treat analysis (δ = 0.01%; 95% confidence interval, -6.7 to 6.8) and 1.2% and 0%, respectively, in the on-treatment analysis (δ = 1.22%; 95% confidence interval, -5.6 to 8.1). At week 24, 88%-89% of patients in both arms had plasma HIV-1 RNA levels <50 copies/mL. No significant CD4 cell count changes occurred in either arm. Grade 3-4 adverse events and laboratory abnormalities were uncommon and were not different between the treatment arms. Conclusion. A switch to raltegravir was safe, well tolerated, and virologically non-inferior to the maintenance of enfuvirtide in patients infected with multidrug-resistant HIV-1 infection who were receiving suppressive antiretroviral therapy.

Background. Early virological response to antiretroviral therapy is predictive of long-term treatment outcome in therapy-naive patients. In treatment-experienced patients, such correlations are less well defined, because initial responses may be less pronounced and transient because of accumulated cross-resistance to prior therapies. Our objectives were to explore how the virological and immunological status of treatment-experienced patients at an early time point (week 12) during enfuvirtide-based therapy predicted their responses at weeks 24, 48, and 96 in the T-20 versus Optimized Regimen Only (TORO) trials. Methods. Post hoc, modified, on-treatment and intent-to-treat analyses were performed to determine whether the relationship between virological and immunological outcomes at weeks 24, 48, and 96 were predicted by the patients' week-12 responses to therapy. Results. Using a modified on-treatment analysis for patients who, by week 12, achieved a decrease in their HIV-1 RNA load of ⩾1 log10 copies/mL, 39.2% (95% CI, 33.6%-44.8%) and 59.5% (95% CI, 53.8%-65.1%) achieved a viral load of <50 copies/mL or <400 copies/mL at week 96, respectively, compared with 1.3% (95% CI, 0%-3.8%) and 2.6% (95% CI, 0%-6.1%) of patients, respectively, who did not achieve an early virological response. Using the same modified on-treatment analysis method for patients who, at week 12, achieved a CD4 cell count increase of ⩾50 cells/mm³, 87.2% (95% CI, 82.6-91.8) maintained or improved this response through week 96, compared with 56.6% (95% CI, 47.5-65.8) of patients who did not achieve this early categorical im- munological response. Conclusion. Enfuvirtide-based treatment regimens are associated with a rapid and durable response. Week-12 virological and immunological responses to treatment with enfrivirtide are predictive of subsequent outcomes in triple-class treatment-experienced patients. [ABSTRACT FROM AUTHOR]

Context Emtricitabine is a new, once-daily nucleoside reverse transcriptase inhibitor (NRTI) with potent activity against human immunodeficiency virus (HIV). Objective To assess the efficacy and safety of emtricitabine as compared with stavudine when used with a background regimen of didanosine and efavirenz. Design, Setting, and Patients Randomized, double-blind, double-dummy study conducted at 101 research clinics in North America, Latin America, and Europe. The first patient was enrolled on August 21, 2000; no investigator or patient was unblinded until the last patient randomized completed the week 48 visit on October 24, 2002. Analyses were based on data collected in a double-blind setting with a median follow-up of 60 weeks. Patients were 571 antiretroviral-naive, HIV-1–infected adults aged 18 years or older with viral load levels greater than or equal to 5000 copies/mL. Interventions Receipt of either 200 mg of emtricitabine once daily (plus stavudine placebo twice daily) (n = 286) or stavudine at standard doses twice daily (plus emtricitabine placebo once daily) (n = 285) plus open-label didanosine and efavirenz, once daily. Main Outcome Measure Persistent virological response, defined as achieving and maintaining viral load at or below the limit of assay quantification (≤400 or 50 copies/mL). Results At the interim analysis on June 14, 2002, when the last patient randomized completed 24 weeks of double-blind treatment (median follow-up time of 42 weeks), patients in the emtricitabine group had a higher probability of a persistent virological response ≤50 copies/mL vs the stavudine group (85% vs 76%, P = .005). This was associated with a higher mean CD4 cell count change from baseline for the emtricitabine group (156 cells/µL vs 119 cells/µL, P = .01 [of note, there was no statistical difference at 48 weeks {P = .15}, although a sensitivity analysis, using an intent-to-treat population with the last CD4 cell count observat...

Introduction NEAT001/ANRS143 was an open-label, randomized, non-inferiority study comparing raltegravir+darunavir/r(RGV+DRV/r) vs. tenofovir/emtricitabine+darunavir/r (TDF/FTC+DRV/r) in HIV-infected antiretroviral naïve adults. Primary efficacy outcome was a composite of virological and clinical events by week 96. Materials and Methods Clinical trial units collected and translated supporting documentation (SD) related to the investigator-reported events. A coordinator checked events and SD for consistency and completeness. The Endpoint Review Committee (ERC) determined if clinical events met pre-defined diagnostic criteria in categories 'confirmed' or 'probable'. The ERC of 12 experienced, independent clinicians served in groups of three conducting individual reviews in writing, blinded to treatment arm. Differences of opinion were adjudicated in a second review by direct dialogue between reviewers. 'Confirmed' events required adequate SD like laboratory, radiographic or pathology diagnostic reports. 'Probable' events were typically based on clinical criteria. Results Of the 164 serious and 3,964 adverse events reported in the study, 133 qualified for endpoint review, for a total of 153 adjudications: Sixty of 111 per protocol endpoints were confirmed (n=53) or probable (n=7), which equals an acceptance rate of 54%. In two confirmed cases, SD was partly adequate and evaluation uncertain. Of 51 rejected events, 13 had insufficient SD, two were recurrent events. The rate of rejected events was comparable between treatments with 41% rejected events in the RGV+DRV/r arm compared to 52% in the TDF/FTC+DRV/r arm. The IRIS acceptance rate was low (3 of 18), demonstrating the difference in perception of IRIS in daily patient management and the stricter protocol definition. Conclusions Blinded endpoint review prevented unacceptably high false positive event rates documenting that real-time ascertainment of clinical endpoints is crucial for appropriateness of the overall results. Non-confirmed events jeopardize the statistical power in this and probably all kinds of clinical studies. The rejection rate was not indicative of poor study conduct - on the contrary over-reporting prevented missing events, which would have adversely impacted the trial. Adequacy of SD and investigator training on possible differences in event criteria in daily pragmatic clinical management compared to protocol defined criteria is essential. [ABSTRACT FROM AUTHOR]

Introduction Sleep disturbances are frequently reported in HIV-infected patients but there is a lack of large studies on prevalence and risk factors, particularly in the context of current improved immuno-clinical status and use of the newest antiretrovirals (ARV). Method Cross-sectional study to evaluate the prevalence and factors associated with sleep disturbance in adult HIV-infected patients in six French centres of the region 'Pays de la Loire'. Patients filled a self-administered questionnaire on their health behaviour, sleep attitudes (Pittsburgh Sleep Quality Index PSQI), quality of life (WHO QOL HIV BREF questionnaire) and depression (Beck depression Inventory (BDI)-II questionnaire). Socio-demographic and immunovirologic data, medical history, ARVs were collected. Results From November 2012 to May 2013, 1354 consecutive non-selected patients were enrolled. Patients' characteristics were: 73.5% male, median age 47 years, active employment 56.7%, France-native 83% and Africa-native 14.7%, CDC stage C 21%, hepatitis co-infection 13%, lipodystrophy 11.8%, dyslipidemia 20%, high BP 15.1%, diabetes 3%, tobacco smokers 39%, marijuana and cocaine users, 11.7% and 1.7% respectively, and excessive alcohol drinkers 9%. Median (med) duration of HIV infection was 12.4 years, med CD4 count was 604/mm3; 94% of Patients were on ARVs, 87% had undetectable viral load. Median sleeping time was 7 hours. Sleep disturbances (defined as PSQI score >5) were observed in 47% of the patients, more frequently in female (56.4%) than in male (43.9%) (p<0.05) and moderate to serious depressive symptoms (BDI score>19) in 19.7% of the patients. In multivariate analysis, factors associated with sleep disturbances (p<0.05) were depression (odds ratio [OR] 4.6; 95% confidence interval [CI] 3.2-6.8), male gender (OR 0.7; CI 0.5-0.9), active employment (OR 0.7; CI 0.5-0.9), living single (OR 1.5; CI 1.2-2.0), tobacco-smoking (OR 1.3; CI 1.0-1.8), duration of HIV infection (>10 vs. <10 y.) (OR 1.5; CI 1.1-2.0), ARV regimen containing nevirapine (OR 0.7; CI 0.5-0.9) or efavirenz (OR 0.5; CI 0.3-0.7). Conclusions Prevalence of sleep disturbances is high in this HIV population and roughly similar to the French population. Associated factors are rather related to social and psychological status than HIV infection. Depression is frequent and should be taken in care to improve sleep quality. [ABSTRACT FROM AUTHOR]

Abstract: The introduction of potent anti-retroviral treatment (ART) has transformed HIV disease into a chronic condition with the prospect, for the patient, of strict adherence to effective but life-long treatments. Within this framework, a major issue that can negatively affect adherence is the side-effects of the treatment. To date, studies documenting how individuals HIV-infected through drug injection (IDUs) experience ART-related side effects are sparse. Longitudinal data collected from the APROCO-COPILOTE cohort have been used to compare the experience of ART-related side-effects who have been HIV-infected via injecting drug use and non-IDU patients. A 20-item list was used to collect self-reported side-effects over a 7-year follow up period. Of 922 patients, 15% were IDUs. At any given visit, IDUs reported a significantly higher number of side-effects and had approximately twice the risk of reporting any side effect than non-IDUs. Most commonly reported side-effects were dry skin, fatigue, vomiting, bone troubles, insomnia. After adjustment for social conditions, depressive symptoms, use of sleeping pills and time since HIV diagnosis, IDUs reported experiencing significantly more side-effects than non-IDUs. Whether or not this is related to sensitivity to pain or to other comorbidities is difficult to establish. Further research is needed to understand how substitution treatment can mediate the relationship between exposure to opioids and side-effects. Providing appropriate care to reduce side-effects, thereby increasing adherence to ART in this population, remains a major challenge especially in those countries scaling up ART. Incorporating symptom management and improving access to analgesic medications within a model of comprehensive care for HIV-infected IDUs, could reduce the impact of drug-related and HIV-related harms and induce better long-term treatment outcomes and quality of life.

Background: Increased rates of sexually transmitted infections (STIs) have been reported among men who have sex with men. We aimed to assess whether post-exposure prophylaxis (PEP) with doxycycline could reduce the incidence of STIs.Methods: All participants attending their scheduled visit in the open-label extension of the ANRS IPERGAY trial in France (men aged 18 years or older having condomless sex with men and using pre-exposure prophylaxis for HIV with tenofovir disoproxil fumarate plus emtricitabine) were eligible for inclusion in this open-label randomised study. Participants were randomly assigned (1:1) at a central site to take a single oral dose of 200 mg doxycycline PEP within 24 h after sex or no prophylaxis. The primary endpoint was the occurrence of a first STI (gonorrhoea, chlamydia, or syphilis) during the 10-month follow-up. The cumulative probability of occurrence of the primary endpoint was estimated in each group with the Kaplan-Meier method and compared with the log-rank test. The primary efficacy analysis was done on the intention-to-treat population, comprising all randomised participants. All participants received risk-reduction counselling and condoms, and were tested regularly for HIV. This trial is registered with ClinicalTrials.gov number, NCT01473472.Findings: Between July 20, 2015, and Jan 21, 2016, we randomly assigned 232 participants (n=116 in the doxycycline PEP group and n=116 in the no-PEP group) who were followed up for a median of 8·7 months (IQR 7·8-9·7). Participants in the PEP group used a median of 680 mg doxycycline per month (IQR 280-1450). 73 participants presented with a new STI during follow-up, 28 in the PEP group (9-month probability 22%, 95% CI 15-32) and 45 in the no-PEP group (42%, 33-53; log-rank test p=0·007). The occurrence of a first STI in participants taking PEP was lower than in those not taking PEP (hazard ratio [HR] 0·53; 95% CI 0·33-0·85; p=0·008). Similar results were observed for the occurrence of a first episode of chlamydia (HR 0·30; 95% CI 0·13-0·70; p=0·006) and of syphilis (0·27; 0·07-0·98; p=0·047); for a first episode of gonorrhoea the results did not differ significantly (HR 0·83; 0·47-1·47; p=0·52). No HIV seroconversion was observed, and 72 (71%) of all 102 STIs were asymptomatic. Rates of serious adverse events were similar in the two study groups. Gastrointestinal adverse events were reported in 62 (53%) participants in the PEP group and 47 (41%) in the no-PEP group (p=0·05).Interpretation: Doxycycline PEP reduced the occurrence of a first episode of bacterial STI in high-risk men who have sex with men.Funding: France Recherche Nord & Sud Sida-HIV Hépatites (ANRS) and Bill & Melinda Gates Foundation.

Background: We conducted subanalyses of the combined results of the Maraviroc versus Optimized Therapy in Viremic Antiretroviral Treatment-Experienced Patients (MOTIVATE) 1 and MOTIVATE 2 studies to better characterize the efficacy and safety of maraviroc in key subgroups of patients. Methods: We analyzed pooled data from week 48 from the two studies according to sex, race or ethnic group, clade, CC chemokine receptor 5 (CCR5) delta32 genotype, viral load at the time of screening, the use or nonuse of enfuvirtide in optimized background therapy (OBT), the baseline CD4 cell count, the number of active antiretroviral drugs coadministered, the first use of selected background agents, and tropism at baseline. Changes in viral tropism and the CD4 count at treatment failure were evaluated. Data on aminotransferase levels in patients coinfected with hepatitis B virus (HBV) or hepatitis C virus (HCV) were also analyzed. Results: A treatment benefit of maraviroc plus OBT over placebo plus OBT was shown in all subgroups, including patients with a low CD4 cell count at baseline, those with a high viral load at screening, and those who had not received active agents in OBT. Analyses of the virologic response according to the first use of selected background drugs showed the additional benefit of adding a potent new drug to maraviroc at the initiation of maraviroc therapy. More patients in whom maraviroc failed had a virus binding to the CXC chemokine receptor 4 (CXCR4) at failure, but there was no evidence of a decrease in the CD4 cell count at failure in such patients as compared with those in whom placebo failed. Subanalyses involving patients coinfected with HBV or HCV revealed no evidence of excess hepatotoxic effects as compared with baseline. Conclusions: Subanalyses of pooled data from week 48 indicate that maraviroc provides a valuable treatment option for a wide spectrum of patients with R5 HIV-1 infection who have been treated previously.
