Filter by:A multicenter, randomized, stratified, open-label, phase IV trial among HIV-positive persons (PLHIV) on antiretroviral therapy (ART), or HIV-negative household contacts of patients with rifampicin-sensitive pulmonary tuberculosis (TB), who do not have evidence of active TB.
The overall goal of this research project is to examine the feasibility, acceptability, and preliminary efficacy of nicotine replacement therapy preloading (NRT-P) in HIV-positive smokers, who are struggling with cigarette dependence, urge to smoke (craving) and low self-efficacy as barriers to successful smoking cessation. Sixty participants will be recruited into a 16-week randomized pilot study. Thirty participants (control condition) will receive standard smoking cessation counseling (NRT-S) and will initiate an 8-week course of combination nicotine patch and lozenge (or gum, based on preference) on quit date (week 4), consistent with recommended guidelines based on smoking rate. Thirty participants (active condition) will start NRT patch 3 weeks prior to quit date, followed by an 8-week course of combination nicotine patch and lozenge (or gum, based on preference), initiated on quit date. The investigators will examine dependence, urge to smoke and self-efficacy for quitting prior to and following quit date. The investigators will also examine differences in quit attempts and biochemically validated smoking abstinence between the control and active conditions at weeks 8, 12, and 16.
The proposed research aims to assess the multiple forms and paths of stigma and substance use as they relate to pre-exposure prophylaxis (PrEP) use for HIV prevention. How stigma and an evolving public health landscape impact PrEP use among Black sexual minorit men who use substances is unknown. The current application focuses on addressing critical and novel questions to improving the essential building blocks of biomedical prevention approaches by providing crucial information for enhancing interventions to lower HIV prevalence among substance using Black sexual minority men.
In summary, in this project the investigators propose to study the proviral DNA genotyping to implement a lower cost and wider than the commercial systems currently in use, in order to analyze all HIV genes that are therapeutic targets of antiretroviral drugs. Using HIV proviral DNA we can obtain information for: HIV-1 Viral Tropism, Mutations associated to Integrase Inhibitors, Mutations associated to Transcriptase reverse Inhibitors, Mutations associated to Protease Inhibitors, and Mutations associated to GP41 Inhibitors. Along with this the investigators propose to validate the proviral DNA as starting material for genotyping which is independent of the patient's viral load and achieve a greater number of patients living with HIV have access to this important test that is essential in monitoring the HIV infection. 3.2 RESEARCH QUESTIONs Is proviral DNA a genetic compartment suitable for carrying out a genotypic resistance test in patients with low or undetectable viral load? Does proviral DNA have the same clinical validity that RNA? 3.3.- HYPOTHESIS A resistance genotyping test carried out by Proviral DNA detects the same mutations associated to resistance that viral RNA. 3.4.- OBJECTIVES: General/Specific General objective Develop a methodology to assess the proviral HIV-1 DNA or RNA as the genetic material for genotyping assays in genes that are targets of pharmacological interest as TR reverse transcriptase and protease (PRO), Integrase or GP41 Inhibitors and HIV tropism. Specific Objectives 1. Carry out genotyping by proviral DNA and compare it with the same genes genotyping performed with viral RNA. 2. Once the correlation between proviral DNA and RNA has shown, standardize a method to use the technique for clinical use in monitoring HIV patients according to each patient's needs. RNA for patients with viral load above 1,000 copies/mL. Proviral DNA for patients with low or undetectable viral load.
The investigators propose that the lack of immune response in InR is driven by HIV-containing platelets that might interact with macrophages and CD4+ T-cells although by different mechanisms. In the one hand, HIV-sheltering platelets might fuel tissue HIV macrophage and in turn T cell reservoirs as observed in InRs and/or maintain a low-level viral replication in macrophages, sustaining a persistent inflammatory profile on in these cells. In the other hand,HIV-sheltering platelets might induce CD4+ T-cells dysfunctions via platelets/ectosomes, although without promoting platelet-to-T-cell HIV transfer/infection, thereby increasing the number of peripheral inflammatory TH17 cells and a TH17/Treg unbalance as observed in InRs. Main Objectives: i) To characterize and the molecular and functional level the platelet factors implicated in HIV transfer to tissue-like macrophages as well as in the immunomodulatory activity of HIV-containing platelets on macrophages and CD4+ T-cells. ii) To interrogate the transfer of HIV-containing platelet-derived mRNA and microRNA to tissue-like macrophages and CD4+ T-cells as one major mechanism of target cell immunomodulation. iii) To investigate the therapeutic potential of anti-platelet aggregation/activation agents (e.g. Abciximab), known to block platelet-immune cell interaction, in improving immune cell functions in vitro and promoting immunological recovery in vivo.
The program " Au labo sans ordo " aims to increase HIV testing coverage, in order to improve the first stage of the HIV care cascade in Paris and the Alpes-Maritimes, areas facing a much higher HIV epidemic than the other regions in metropolitan France. Both departments are engaged in the Fast Track Cities Initiative.
This pragmatic, multisite, implementation and effectiveness research evaluates a strategy to improve HIV treatment outcomes (increased rates of patients on ART with virological suppression, improved treatment retention and ART adherence) for people living with HIV (PLWH) with opioid use disorder (OUD). Engaging 4 large regional HIV/AIDS treatment centers in Malaysia, the study will evaluate barriers and facilitators for implementation of improved care model and will evaluate the comparative effectiveness of the model in a clinical trial. The research will provide critically important evidence for implementation of effective Seek-Test-Treat, and Retain models for PLWH and OUD throughout Malaysia and inform healthcare policy in other low to middle income countries and regions with limited healthcare resources.
This study compares several different antiretroviral adherence measures, including digital pills, in HIV+ individuals who are maintained on opioid analgesics.

The objective of this research is to measure the short- and mid-term effects of an empowerment program focused on serostatus disclosure management for women living with HIV (WLHIV) in Mali on the "burden of secrecy".
