Chronic immune activation present in aviremic people living with HIV under treatment promotes the onset of insulin resistance and metabolic syndrome, paving the way for the comorbidities that are currently the main causes of morbidity. This activation continues despite effective antiretroviral therapy. In the ACTIVIH study (NCT02334943) the analysis of 68 AI markers allowed classification of 120 aviremic PLHIV under treatment for at least 2 years according to 5 different immune activation profiles. Among these 5 profiles, Profile 2 was characterized by high blood pressure figures, high waist sizes, low HDL-cholesterol levels, high triglyceridemia, and especially hyperinsulinemia. Several studies have shown that the digestive microbiota of this population is less rich and less diverse than that of healthy subjects. However, the digestive microbiota and in particular bacterial proteins and metabolites seem to play a key role in immune activation in people living with HIV. Finally, the digestive microbiota has already been shown to have an impact on insulin sensitivity. The study investigators hypothesize that a particular digestive microbiota could promote the appearance of Profile 2. This microbiota could be the cause of digestive dysbiosis leading to intestinal inflammation, digestive permeability and bacterial translocation.
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of an islatravir (ISL)-eluting implant. Participants will receive an implant placed in the upper arm for approximately 52 weeks with 8 weeks of follow-up in the Base Study. A subset of participants will also receive a second implant for an additional 12 weeks before 8 weeks of follow-up in the Substudy.
Several barriers prevent the remission of HIV infection: low level viremia, HIV latency in the genome of host infected immune cells and persistent immune activation. Targeting immune activation and viral latency, represent the two intimately intricate goals to be envisaged for purging the reservoir, in the perspective of HIV cure. There is an urgent to develop and to test drugs targeting HIV latency, HIV residual replication and immune activation, alone or in synergistic combinations. We propose in this study to test agents with a potential effect on HIV latency by combining classical agents and newly discovered agents. The Pitié-Salpêtrière virology group has identified some new diaminopiperidine based compounds that have some antilatency properties through an activation of transcription. Compounds of this new class will be tested in combination with classical agents (HDAC inhibitors, HMT inhibitors, inducers of P-TEFb release, PKC agonists, DNMT inhibitors) and less toxic compounds from classical categories for which Carine Van Lint (University of Brussels) has obtained preliminary HIV reactivation data. All the experimentations will be conducted in J-Lat cells and in ex- vivo CD4 cells sampled in patients from the Pitié-Salpêtrière HIV cohort.
This is a single-center, open-label, fixed sequence, pharmacokinetic interaction study between bictegravir and tenofovir alafenamide with rifapentine dosed either daily or weekly. Primary Aims - To assess the effect of once-weekly rifapentine on the steady-state PK of BIC - To assess the effect of once-daily rifapentine on the steady-state PK of BIC Secondary Aims - To assess the effect of daily dosed rifapentine on steady-state PK of TAF (measured as plasma and IC concentrations of TFV-DP) - To assess the effect and timing of interactions of weekly dosed rifapentine on steady-state PK of TAF (measured as plasma and IC concentrations of TFV-DP) - To assess the safety of BIC/TAF/FTC when coadministered with once-weekly or once-daily rifapentine
Many countries in sub-Saharan Africa are implementing a policy of six-month dispensing of antiretroviral (ARV) medications for HIV. Under the new guidelines, stable patients can receive a six-month supply of ARV medications at once, reducing the number of clinic visits required for medication refills. South Africa is considering this policy but has not yet adopted it and has requested evidence of its feasibility, effectiveness, and costs to the healthcare system and to patients. The decision on whether to implement a six-month dispensing policy has become urgent due to the SARS-Cov-2 epidemic, as clinic visits to refill prescriptions pose COVID-19 transmission risks to both patients and providers. To generate the required evidence, South Africa is implementing a pilot program that will allow for a cluster-randomized evaluation of 6-month dispensing. This protocol is for that evaluation. It aims to provide supporting evidence to inform future policy and procurement decisions by the National Department of Health (NDOH). All interventions will be conducted as part of routine care by Department of Health staff. In the pilot program, the NDOH will randomize 28 clinics in two provinces 1:1 to receive the six month dispensing intervention or continue standard of care, which currently allows for 2-3 month dispensing. The researchers will assess the patient outcomes of six month dispensing, administer a cross-sectional patient questionnaire, conduct semi-structured in-depth interviews with care providers and implementers, and estimate the costs to NDOH and to patients of six month dispensing. A maximum of 150,545 patients will be followed through their medical records and 400 patients and providers will be consented to be interviewed at baseline and after 6 months (total maximum sample size = 150,945).
Clinical manifestations of Covid-19 are poorly characterised in HIV co-infection, which may predispose to more severe disease. Reducing hospitalisation and severe illness in this population has important individual and public health benefits. The investigators propose a pragmatic multi-centre, randomized controlled trial in South Africa to evaluate the efficacy and safety of chloroquine or hydroxychloroquine to prevent progression of disease and hospitalisation amongst HIV-positive people with Covid-19 not requiring hospitalisation at initial assessment.
People living with HIV are living longer as their disease is controlled with antiretroviral medications. Yet they are experiencing frailty more often and more than ten years earlier than those without HIV. In elderly persons without HIV, frailty is associated with decreased muscle strength and chronic inflammation. Less is known about what is driving early frailty in HIV or effective prevention measures for aging adults with HIV. It may be that having HIV infection impairs energy production by mitochondria within the cells and contributes to the muscle weakness and inflammation accompanying frailty in people living with HIV . This study will examine the impact of six weeks of moderately paced walking on energy production in the cells, inflammation markers and frailty scores in people living with well-controlled HIV who are aged 50 to 65.
Cigarette smoking remains highly prevalent among persons living with HIV (PLWH). Quitting smoking can have important health benefits for this population. However, PLWH have historically had a difficult time quitting smoking. This is likely due, at least in part, to poor medication adherence. Poor adherence to medication is a well-documented issue among PLWH. Research shows that not taking smoking cessation medications as prescribed can limit their treatment effectiveness. Improving adherence to smoking cessation medications will likely increase smoking cessation attempt success. Mobile phone applications and behavioral interventions show promise for improving adherence to smoking cessation medications and cessation outcomes among PLWH. Therefore, this trial will assess 1) whether a mobile phone application is a feasible and acceptable intervention for improving medication adherence; 2) whether use of the mobile phone app improves adherence to varenicline; and 3) smoking cessation outcomes.
