Active clinical trials for "HIV Infections"

Purpose: The purpose of this study is to determine if a comprehensive intervention supporting seek-test-and-treat results in a significant reduction in the potential for HIV-infected prisoners to transmit their virus after release from prison. Aim 2: Compare the effect of standard prison test-and-treat (sTNT) with the TNT-imPACT (imPACT) intervention on viral load 24 weeks following prison release. Aim 3: Describe and model secondary outcomes, comparing them between sTNT and TNT-imPACT study arms. These outcomes include post-release HIV transmission risk behaviors, incident STIs, adherence to ART, medical care appointments, emergence of ART resistance mutations, and predicted HIV transmission events.

The investigators' objective is to describe the variability of rifampicin absorption, markers of inflammation and gut damage, intestinal absorptive capacity, and intestinal permeability among HIV-infected volunteers. Rifampicin is the least well absorbed of the first-line anti-tuberculosis drugs. Rifampicin malabsorption is frequently observed in HIV-infected patients with active tuberculosis, but cannot be predicted by patient factors such as CD4+ T cell count, viral load, or the presence of diarrhea. The mechanisms for rifampicin malabsorption in HIV-infected patients are unknown. An understanding of mechanisms for rifampicin malabsorption could eventually lead to new therapeutic targets, with the ultimate goal of improving HIV/tuberculosis treatment outcomes.

This is a single-center, randomized, two part, open-label, crossover study in healthy adult subjects to assess the oral bioavailability of three GSK2248761 Wet Bead Milled (WBM) tablet formulations manufactured by three different processes relative to the GSK2248761 WBM capsule formulation (Part A) and the effect of a moderate-fat meal on the bioavailability of the selected WBM tablet formulation (Part B).

A study in healthy volunteers to determine whether there is a drug interaction between GSK1349572 and the HIV protease inhibitors lopinavir/ritonavir and darunavir/ritonavir

This study is being conducted to look at how the body handles the drug maraviroc. It will measure the amount of maraviroc in blood, semen, saliva and in the rectum of men. The aim is to understand how much of the drug (taken by mouth) reaches the oral, reproductive and intestinal tracts. It is believed that the presence of this drug in these areas may be beneficial in preventing the AIDS virus (HIV) from being passed from one person to another. The study will take samples of blood, saliva, semen and rectal mucosal tissue to measure drug levels. This study will also collect information on side effects.

The "PLUS" study is a pilot study to measure the effect of therapy intensification (with raltegravir and optional second agent) on HIV levels in the gut and blood in patients on antiretroviral therapy (ART) with viral load < 50 copies/mL (herein referred to as "suppressed"). We hypothesize that there is ongoing replication in the gut despite suppressive ART and that this replication can be inhibited by the addition of one or two new antiretroviral drugs whose activity affects a distinct part of the viral life cycle. All study participants will have upper and lower endoscopy at baseline (before intensification) and after intensification. These endoscopies will be used to obtain gut tissue and single cells (for CD4+ cells) .

The purpose of this study is to test a mother-to-mother intervention during pregnancy and after delivery with Mothers Living with HIV (MLH)in South Africa. We hypothesize that the intervention will enhance the adjustment of the children of MLH by improving the health and mental health of MLH which benefits their children, as well as the MLH.

To confirm safety and pharmacokinetics of maraviroc following a single oral dose of 300 mg maraviroc in healthy male Japanese volunteers.

To evaluate the effectiveness of nutrition education and dietary counselling to improve the nutritional status, well-being and quality of life of people living with HIV/AIDS (PLWHA) attending an HIV treatment facility in Bangkok Thailand.

The purpose of the study is to study the effects of switching from an antiretroviral combination that includes two ritonavir boosted protease inhibitors to replacement of these two protease inhibitors with a new protease inhibitor called Darunavir (also boosted with ritonavir). The study will investigate the effect of the switch on viral load (the levels of the HIV virus in the blood), on immunological parameters (CD4 count) and on other safety parameters and also on quality of life. In a subgroup of patients the impact of the switch on the body's response to the hormone insulin will also be measured (Euglycaemic clamp sub group)
