Active clinical trials for "HIV Infections"

The aim of the study is to observe the tolerability and effectiveness of Kaletra in Human Immunodeficiency Virus/Hepatitis-B Virus and Human Immunodeficiency Virus/Hepatitis-C Virus co-infected patients.

The present study is designed as a prospective observational study directed at evaluating the frequency, magnitude, quality and persistence (primary endpoint) of the anti-Tat immune response in highly active antiretroviral therapy (HAART)-receiving HIV-1 infected individuals, and to prospectively evaluate the immunological, virological and clinical outcome of anti-Tat positive versus anti-Tat negative subjects under successful HAART (secondary endpoint), in order to determine the impact of anti-Tat immunity on HIV disease progression as well as the potential use of anti-Tat immune response assessment for the clinical and therapeutic management of HAART-treated infected patients. This survey provided important information for the design, planning and conduction of future therapeutic vaccine trials based on the HIV-1 Tat protein in HAART-treated patients.

The primary objective of this trial was to assess the presence of susceptibility to tipranavir and other ARVs of the HIV-1 isolates in treatment experienced patients. The secondary objective was to examine clinicians' use of HIV drug resistance testing in treatment experienced patients currently failing a PI based HAART regimen.

The purpose of this study is to develop and test the efficacy of online HIV risk reduction interventions among men who have sex with men.

The purpose of this study is to assess populations in Thailand at high risk for HIV-1 infection for potential efficacy trials of candidate HIV vaccines to include: assess incidence of HIV-1 and volunteer retention describe early viral load and CD4 counts assess participant willingness to participate in HIV vaccine efficacy trials and other HIV prevention trials describe volunteer risk behavior

Advocacy groups have voiced concerns about the ethics of some of tenets of the CDC's new HIV testing recommendations for the healthcare setting. Three concerns are paramount: (1) the opt-out approach to HIV testing can potentially be coercive and not truly voluntary; (2) by replacing informed consent with general consent for medical care, test participants might not know or be adequately informed of the benefits and consequences of testing; and (3) eliminating HIV prevention counseling from the HIV testing process presumes that test participants are aware of how to prevent an HIV infection, which might not be correct. This study involves conducting interviews of HIV advocates who are raising these concerns, surveying outpatient and emergency department clinical providers about their beliefs and opinions regarding the tenets of the new guidelines, and then conducting a multi-center, randomized, controlled trial in which the ethical concerns of opt-out vs. opt-in testing are directly compared. We will conduct a multi-center, randomized, controlled, trial whereby patients will be surveyed on their perspectives and perceptions regarding opt-out or opt-in rapid HIV testing. We will survey the participants regarding their perception of coercion, their understanding of the elements contained in the informed consent process, their HIV risk factors, and their knowledge of HIV prevention. We will evaluate whether or not the CDC-recommended approaches regarding opt-out testing, consent, and decoupling of prevention counseling are supported. If there are no differences regarding these ethical concerns between testing approaches, then the opt-out approach would be considered not to be inferior to the opt-in approach.

Tenofovir (TDF)-containing regimens may be associated with decreasing renal function in HIV-infected patients concurrently treated with boosted PI's and/or have co-morbid conditions including diabetes mellitus, hypertension, anemia, hepatitis B, and hepatitis C.

The purpose of this observational study is to characterize which immune system cells hide the latent reservoir of HIV by counting the number of latent HIV in different subsets of CD4 cells. Observations will also be made on other possible mechanisms of HIV persistence by looking at cellular factors such as APOBEC3 and drug transporters. The purpose of this study is to develop new strategies to reduce and possibly eliminate the latent reservoir in HIV infected adults.

Does subtype of HIV-1 affect the response of ARVs given to Ugandan children

This study will compare methods of determining whether HIV-infected children take their medications.
