Active clinical trials for "HIV Infections"

This study is the first to try this product in the rectum of humans. This study is only to find out if the gel is safe for use in the rectum, not to see if the gel works. Information gathered from this study will help investigators decide whether this gel is safe enough to move onto the next phase of studies. Information gathered from this study will also help investigators determine what participants did and did not like about the product and what types of products people might want to use in the future. Currently condoms and abstinence are the only methods proven to prevent the spread of HIV sexually.

The main objective of the study is to assess changes in fat distribution over 48 weeks of treatment in patients who currently successfully use zidovudine (AZT) and lamivudine (3TC) as part of their regimen and who will either continue these antiretrovirals or who will switch these antiretrovirals to tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC). Each of these medications is commonly used for the treatment of HIV-1 infection.

The purpose of this study is to assess differences in changes in plasma lipids between patients on saquinavir/ritonavir or atazanavir/ritonavir in combination with tenofovir disoproxil fumarate and emtricitabine as a first-line regimen in patients previously naive for antiretroviral therapy. This study is an extension from the SSAR 2004/0002 which randomised patients over the same treatment arms.

Connect to Protect (C2P): Partnerships for Youth Prevention Interventions is a multi-site, three-phase project developed by the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN). The overall goal of the project is to ultimately reduce HIV incidence and prevalence in youth 12-24 years old through a community mobilization intervention. This protocol (ATN 040) describes part one of Phase III. Part two of Phase III will be submitted as a separate protocol (ATN 041).

Approximately 36 HIV-negative women, aged >18 and < 50, will be enrolled in this study. Each volunteer will have a 2:1 chance of receiving dapivirine gel versus placebo. The volunteers will receive investigational product for a total of 42 days.

Over 80% of HIV-1 infected persons are also seropositive for HSV-2. Increasingly, clinical and epidemiologic evidence show the role of HSV in increasing HIV infectiousness. The evidence suggests that that HSV is an important cofactor in HIV transmission. The trial's purpose is to assess the reduction in HIV shedding associated with valacyclovir for suppression of HSV-2 reactivation. This proof-of-concept, randomized, double-blind, placebo controlled crossover trial of 20 HIV/HSV-2 co-infected men, assessed the effects of daily valacyclovir on HIV-1 levels in the plasma and rectal mucosa secretions.

The objectives of this clinical trial are to: Assess the safety of using extracorporeal photoimmune therapy with the photosensitizing agent Uvadex in the treatment of HIV-1 infection; Evaluate the effects of this therapy on HIV-1 viral load by polymerase chain reaction (PCR) analysis; Evaluate the effects of this therapy on CD4+, CD8+ cells and CD4/CD8 ratio; Evaluate the effects of this therapy on the patient's immune system, by skin reactivity to a standard anergy panel.

Genital herpes is a long-life sexually transmitted diseases which infects a large proportion of women in Africa. Its clinical symptoms are painful sores on the genitals, which heals after a few days. HIV infection can worsen genital herpes. In turn, it is possible that genital herpes increases the quantity of HIV secreted at the genital level in women infected by the 2 viruses. This study is dedicated to verify this hypothesis.

Micronutrient deficiencies are common in HIV infected children and are aggravated by poor nutrition, especially in poor resource countries such as Uganda. It appears that micronutrient deficiencies contribute to immune dysfunction, increased morbidity and HIV disease progression. Hitherto, there has been no randomised controlled trial to assess the effect of multiple micronutrient supplementation on morbidity and mortality in HIV infected children in Africa. Therefore, the investigators shall carry out a randomised controlled trial to determine the effect of multiple micronutrient supplementation on morbidity, weight gain and mortality among HIV infected children aged 1 to 5 years in Uganda. Hypothesis: Daily administration of twice the recommended dietary allowance (2RDA) of multiple micronutrients to HIV infected children aged one to five years, for 6 months, will reduce all cause mortality from 24% to 14.4% in one year and result in a weight gain difference of 150 grams.

The purpose of this study is to examine the drug interactions between a protease inhibitor (PI)-based regimen including lopinavir/ritonavir (LPV/r) and two forms of contraceptive medications in HIV infected women.
