OBJECTIVE: The contribution of HLA-DR+ memory CD4+ T-cells to the HIV reservoir during prolonged antiretroviral therapy is unclear as these cells are commonly excluded when assessing for replication-competent HIV. To address this issue, we examined the distribution of genetically intact HIV DNA within HLA-DR- and HLA-DR+ memory CD4 T-cells and the RNA transcriptional profile of these cells during ART. DESIGN/METHODS: Full-length DNA sequencing was used to examine the HIV DNA landscape within HLA-DR+ and HLA-DR- memory CD4+ T-cells...

: Elite controllers or suppressors (ES) control viral replication without antiretroviral therapy (ART). We used the intact proviral DNA assay to approximate the size of the inducible latent reservoir in ES and found that while the median frequency of both total and intact proviral DNA was markedly lower than the frequencies seen in chronic progressors (CP) on ART, there was no significant difference in the ratio of intact to total proviral DNA between ES and CP.

OBJECTIVE: Evaluate the potential effectiveness of the implementation of DTG-based regimens in patients on failing current ART given the high levels of NRTI resistance in Togo. DESIGN: Patients on ART attending health facilities for routine follow-up visits and for whom HIV viral load (VL) test was performed were consecutively included. METHODS: Protease, Reverse Transcriptase (RT) and Integrase fragments were sequenced and analyzed for presence of drug resistance mutations (DRMs) for patients with VL > 1,000 copies/mL...

: Integrase inhibitor-based antiretroviral therapy (INSTI-ART) can cause weight gain. It is unknown if this is a class effect, with limited data regarding raltegravir. In 37 virologically suppressed adults (36 men, mean age 49 years) who switched from tenofovir disoproxil fumarate to raltegravir 400 mg twice daily, mean weight changes from baseline at Weeks 24, 48 and 96 were not significant (maximum 0.8 kg at Week 24; all p≥0.16). Weight gain may not occur with all INSTIs.

OBJECTIVE: Chronic hepatitis C virus (HCV) and hepatitis virus (HBV) infections are associated with increased risks of lymphomas in the non-HIV setting. Their impacts on HIV-associated lymphomas deserved further studies in the modern combined antiretroviral therapy (cART) era. DESIGN: We evaluated the associations between HCV, HBV and HIV-related lymphomas in the Lymphovir-ANRS-CO16 cohort. METHODS: Prevalence of HCV-seropositivity and chronic HBV infections were compared to those observed in the French Hospital Database on HIV (FHDH-ANRS-CO4)...

BACKGROUND: Darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) 800/150/200/10mg was investigated through 96 weeks in AMBER (NCT02431247). METHODS: Treatment-naïve, HIV-1-positive adults (screening plasma viral load [VL]≥1000 copies/ml; CD4 count >50 cells/mm) were randomized (1:1) to D/C/F/TAF (N=362) or D/C plus emtricitabine/tenofovir-disoproxil-fumarate (F/TDF) (N=363) over ≥48 weeks.

OBJECTIVE: People living with HIV have an increased risk of cardiovascular disease (CVD) despite effective antiretroviral therapy (ART). Monocytes play a key role in the early stages of atherosclerosis-driven CVD by forming lipid-laden foam cells within artery walls. HIV infection potentiates foam cell formation ex vivo, but the mechanisms contributing to this are not known. METHODS: We investigated the atherosclerosis-promoting potential of monocytes from 39 virologically suppressed men living with HIV (MLHIV) on ART and no evidence of CVD, and 25 HIV-uninfected controls of comparable age, sex, smoking status and CVD risk...

OBJECTIVE: Around 20-30% of HIV-infected subjects (HIV+) on successful antiretroviral therapy (ART) fail to normalize their CD4+ T cell counts. Various factors could contribute to the lack of immune reconstitution (IR), one of them being thymic insufficiency. We aimed to explore associations between recent thymic emigrants (RTEs) and CD4+ T cell recovery. DESIGN: ART-naïve HIV+ subjects who started ART with advanced AIDS were selected. Good versus poor IR was defined by CD4 gains above or below 100 CD4+ T cells/mm...

OBJECTIVE: To evaluate the effects of HIV preexposure prophylaxis (PrEP) with tenofovir disoproxial fumurate (TDF)/emtricitabine (FTC) on kidney function and kidney tubular health. DESIGN: The Iniciativa Profilaxis Pre-Exposicion open-label extension (iPrEx-OLE) study enrolled former PrEP trial participants to receive open-label TDF/FTC. This study included 123 iPrEx-OLE participants who demonstrated PrEP adherence. METHODS: We compared estimated glomerular filtration rate calculated using serum creatinine (eGFRcr), serum cystatin C (eGFRcys), and in combination (eGFRcr-cys), and a panel of 14 urine biomarkers reflecting kidney tubular health before and 6 months after PrEP initiation...

BACKGROUND: To develop a predictive model to prioritize persons with a transmissible HIV viral load for transmission-reduction interventions. METHODS: New York City (NYC) HIV molecular surveillance data from 2010 to 2013 were used to build a model to predict the probability that the partial pol gene of the virus of a person with a transmissible HIV viral load (>1500 copies/ml) would be genetically similar to that of a person with a new HIV infection (diagnosis at stage 0 or 1 according to the revised Centers for Disease Control and Prevention classification system)...

OBJECTIVE: To compare alternative methods of adjusting self-reported knowledge of HIV-positive status and antiretroviral (ARV) therapy use based on undetectable viral load (UVL) and ARV detection in blood. DESIGN: Post hoc analysis of nationally representative household survey to compare alternative biomarker-based adjustments to population HIV indicators. METHODS: We reclassified HIV-positive participants aged 15-64 years in the 2012 Kenya AIDS Indicator Survey (KAIS) that were unaware of their HIV-positive status by self-report as aware and on antiretroviral treatment if either ARVs were detected or viral load was undetectable (<550 copies/ml) on dried blood spots...
