Active clinical trials for "Acquired Immunodeficiency Syndrome"

The aim of this study is to investigate the benefits of ARV treatment to patients, to the family members of patients on ARV treatment, and to communities at large. The study also aims to investigate the impact of a peer adherence support and a nutritional intervention on measures of treatment success. To this end, 648 patients who had commenced ARV treatment in the past month at twelve selected health care facilities will be recruited into the study. In addition, 204 randomly sampled households from the communities served by the twelve selected clinics will be recruited into the study. Trained enumerators will at baseline conduct semi-structured interviews with patients and households. Following the baseline survey, patients recruited into the study will be randomly assigned to one of three groups: Patients receiving ARV treatment and the associated support currently provided in the public sector ARV treatment programme. Patients receiving (a) plus bi-weekly visits by an experienced ARV patient who has been trained as a peer adherence supporter Patients receiving (a) and (b) plus a weekly nutritional supplement in the form of two 400g cans of meatballs and spaghetti in tomato sauce The group of 'comparison' households comprises the fourth group. Trained enumerators will conduct follow-up interviews with all patients and households at approximately six- and at twelve-months respectively. In addition, the ARV coordinator and other providers working in the ARV treatment programme at each of the twelve selected health care facilities will be interviewed by trained enumerators, at baseline and again at six- and at twelve-months. Clinical data will be obtained from patient files at baseline and at completion of the study. Using these data, various outcomes of importance to the study will be compared between the four study groups, using experimental and non-experimental methods.

The purpose of this study is to evaluate a peer-based HIV prevention intervention that targets active injection drug users and their drug and sex partners in Chennai India.

To study the collection of blood from individuals known to be at high risk for HIV-infection or who have been recently infected with HIV. The data collected are used for diagnostic, prognostic and management decisions as outlined by current HIV-1 Treatment Guidelines.

The development of a safe and effective vaccine is the best strategy for preventing the spread of HIV-1. The purpose of this study is to determine the safety and effectiveness of and immune responses to an HIV vaccine regimen in healthy adults at risk for HIV infection.

Ritonavir boosted protease inhibitor based therapy will have equivalent antiviral efficacy over 48 weeks compared to NNRTI based therapy in patients who are antiretroviral therapy naïve and initiate therapy with CD4 counts ≤ 200/mm3.

Title: Randomized clinical trial to assess the efficacy of short course intermittent regimens for the treatment of HIV-associated tuberculosis Phase: Phase III trial Population: 300 HIV positive patients with tuberculosis. Number of Sites:Four Tuberculosis Research Centre, Chennai Government General Hospital, Chennai Government Hospital of Thoracic Medicine, Tambaram Government Rajaji Hospital, Madurai Study Duration:36 months Study Objective:To study the efficacy of the standard RNTCP Category I regimen (2EHRZ3 / 4RH3) the control arm vs. an extended continuation phase regimen 2EHRZ3 / 7 RH3 in the treatment of pulmonary and extrapulmonary TB in the HIV positive patients. 2. To study the relationship between stage of HIV disease and response to anti-TB treatment. 3. To study recurrences and their nature (relapse/re-infection) in detail by using RFLP analysis. Study Design:It is a two armed prospective randomized open label controlled clinical trial with stratified random allocation based on CD4 count and sputum smear grade. All enrolled patients will be treated according to the RNTCP guidelines during the intensive phase. In the continuation phase, Cat I patients will be stratified by CD4 counts and by smear grade, and randomly allocated either to the standard RNTCP regimen, or to an alternative extended regimen (2EHRZ3/4RH3 or 2EHRZ3/7RH3).

This project is designed to 1) develop a PrEP implementation plan for a general adolescent clinic. Investigators will develop a replicable implementation plan for providing PrEP to adolescents in a primary care setting; and 2) Determine the acceptability and preliminary effectiveness of a telehealth intervention to promote adherence in adolescents.

This trial evaluates options for second-line antiretroviral therapy in patients failing on a non-nucleoside reverse transcriptase inhibitor (NNRTI) and tenofovir (TDF)-based first-line regimen in the setting of the public health approach in sub-Saharan Africa (with assumed substantial nucleoside reverse transcriptase inhibitor (NRTI) cross-resistance). The trial tests two hypotheses. Firstly that a regimen of dolutegravir (DTG) with two NRTIs is non-inferior to a regimen of ritonavir-boosted darunavir (DRV/r) with two NRTIs. Secondly that continuing an NRTI regimen of TDF and lamivudine (3TC) is non-inferior to switching to zidovudine (ZDV) and 3TC. The trial is a parallel group, open-label, multi-centre, factorial (2X2) randomised, controlled trial. Patients will be randomised to either DTG or DRV/r with a second randomisation to ZDV and 3TC or TDF and 3TC. Treatment efficacy will be monitored by testing viral load (VL). Analyses will compare DRV/r with DTG; and ZDV/3TC with TDF/3TC by intention to treat analysis on the primary outcome parameter of plasma VL below 400 copies/ml at 48 weeks. Trial follow-up will continue to 96 weeks.

Through a multi-center large-sample non-randomized controlled study, the effect of voriconazole, amphotericin B sequential itraconazole therapy on Talaromyces in Human Immunodeficiency Virus（HIV）negative hosts were compared to clarify whether the two therapies were equivalent; A comprehensive efficacy evaluation system and standard treatment program was established to provide a basis for standardized treatment of Talaromyces in Human Immunodeficiency Virus negative hosts.The observational indicators included: 2-week all-cause mortality; 24-week all-cause mortality; clinical improvement time; level of decrease of fungus in the blood culture medium two weeks before treatment; recurrence; appearance of adverse drug reaction at the level 3 and above. Dynamically monitor the immune cells and factors like anti-Interferon-γ autoantibodies, Interferon-γ, Th1/Th2, and Th17/Treg in the HIV-negative Talaromyces host microenvironment, and observe the host's immune status and its change. 3. study the effect of absence of Interferon-γ and Interferon-γ Receptor (IFN-γR）on the activation and function of anti-Interferon-γ autoantibodies, Th1/Th2, and Th17/Treg by establishing a Talaromyces mouse model that knocks out the Interferon-γ and IFN-γR gene and a IFN-γ silenced cell model; Study the effect of anti-IFN-γ autoantibody on the activation and function of IFN-γ、Th1/Th2、Th17/Treg by increasing its titer in vitro and vivo; determine by which path the anti-IFN-γ autoantibody of HIV-negative host influences its immune regulation mechanism; finally, the intervention effect of IFN-γ on high titer anti-IFN-γ autoantibodies is studied, providing a new idea for immunotargeted therapy.

Multicenter, randomized, open label pilot clinical trial with two parallel arms aimed to compare the efficacy of Raltegravir (RAL) 1200mg QD vs Darunavir/Cobicistat (DRV-cb) 800-150mg QD both in combination with alafenamide/emtricitabine (TAF/FTC) in patients with Human Inmunodefficiency Virus (HIV) infection and CD4<200 cells/microL
