Active clinical trials for "HIV Infections"

The aim of this study is to evaluate the efficacy for the recovery of peripheral fat of lopinavir/ritonavir in monotherapy versus abacavir/lamivudine and lopinavir/ritonavir in subjects who developed lipoatrophy while receiving zidovudine plus lamivudine plus abacavir.

This study will evaluate the safety and preliminary immune response to recombinant adenoviral serotype 35 and 5 HIV-1 vaccines in HIV-uninfected adults.

This study will test the effectiveness of a program aimed at reducing behaviors that increase HIV risk among people with severe mental illnesses.

This study evaluated the educational effectiveness of a youth-friendly pre-test video (derived from a previous qualitative study) and compared it with in-person HIV pre-test counseling. A convenience sample of 200 medically stable individuals between the ages of 15 and 21 presenting to an urban ED were recruited to participate in this study and randomized into 2 groups. Individuals were eligible if they were English-speaking, sexually active and able to consent. All participants completed a sexual risk factor and demographic survey. Group 1 completed a validated pre-test knowledge measure, viewed the HIV education video then completed a post-test knowledge measure. Group 2 completed the same knowledge measures, but received pre-test HIV counseling from a trained public health advocate. HIV testing was optional

The purpose of this study is to determine if 30-day survival will be improved with addition of prednisone to standard tuberculosis (TB) therapy.

This study tested whether taking a pill of tenofovir and emtricitabine (two antiretroviral medicines) was safe for sexually-active young adults in Botswana without HIV infection and whether it reduced their risk of getting an HIV infection.

GSK has constructed a new HIV immunogen comprised of conserved parts of the HIV virus (gag, pol and nef). The principal objectives of this study are to evaluate the reactogenicity and safety of this candidate vaccine with or without a GSK proprietary adjuvant system at three different doses and to evaluate the CD4+ T-cell response in terms of proportion of responders to the antigens two weeks after the second vaccination.

Highly active antiretroviral therapy (HAART) in HIV-positive patients is associated with the development of dyslipidemia, a risk factor for cardiovascular events. The objective of this study was to evaluate the effect of dietary intervention in individuals who start HAART.

This study will test whether two experimental HIV vaccines are safe and whether they cause any side effects in healthy adults. It will examine the body s immune response to the vaccines and monitor the social impact, if any, of being in an HIV vaccine study. The experimental vaccines in this study are the VRC-HIVADV027-00-VP (also called the rAd35-EnvA vaccine) and VRC-HIVADV038-00-VP (also called the rAd5-EnvA vaccine). The vaccines are made using an adenovirus (virus that normally causes respiratory infections and colds) that has been modified to contain DNA that codes for HIV proteins. The vaccines cannot cause HIV or adenoviral infections. Healthy normal volunteers between 18 and 50 years of age may be eligible for this 2-part study. Part 1 includes 15 people. Part 2 includes 20 people. Part 1 participants receive only the rAd35-EnvA vaccine. The first five people enrolled receive the lowest study dose of the vaccine. If this dose is safe, then the next five people enrolled receive a higher dose. If this dose is safe, then the last 5 people enrolled receive the highest study dose. Subjects in Part I have about five clinic visits over 24 weeks. Part II of the study starts after all injections in Part 1 are given. Subjects in Part 2 are randomly assigned to one of two vaccination schedules. One group receives the rAd35-EnvA vaccine first, followed 12 weeks later with the rAd5-EnvA vaccine. The other group receives the vaccines in reverse order; that is, first the rAd5-EnvA vaccine, followed 12 weeks later with the rAd35-EnvA vaccine. In this schedule, the first vaccination primes the immune system and then the immune response is boosted 12 weeks later with a different vaccine. Everyone in study Part 2 receives the rAd35-EnvA vaccine at the middle dose tested in Part 1. Subjects in Part 2 have about eight clinic visits over 36 weeks. All vaccinations are given as injections in the upper arm. At each clinic visit, participants are checked for health changes or problems. They are asked how they are feeling and if they have taken any medications. Urine samples are collected and blood is drawn at some visits. They are tested for HIV several times and asked questions about their sexual behavior and drug use. Throughout the study, participants are counseled on HIV risk reduction. Subjects are asked about any social effects they may have experienced from their participation in this study.

This study is designed to evaluate the safety of MVA85A in asymptomatic volunteers in South Africa who are infected with M.tb, HIV or both. A single vaccination with MVA85A, when administered at a dose of 5 x 107pfu intradermally, is safe and highly immunogenic in mycobacterially naïve individuals, BCG vaccinated individuals and M.tb latently infected individuals. We will use the same vaccination regime in this study. Participants will be defined as being infected with M.tb.if they have a positive Elispot response to ESAT6 or CFP10. Participants will be defined as being infected with HIV.if they have a positive HIV rapid test (Determine®, Abbott Laboratories) followed by a positive HIV ELISA result. Participants will be identified from the general population living in Worcester, Western Cape, South Africa
