Filter by:The metabolic effects of T-20 are not completely known, since the drug is used in combination with other antiretroviral agents. A short-term study in healthy volunteers, with a double-blind crossover design vs. placebo will illustrate if there may be some direct metabolic effects without the influence of HIV infection and the concurrent use of other drugs.
We hypothesize that the hearts of HIV+ people with The Metabolic Syndrome use and oxidize fats and sugars inappropriately, and that this may impair the heart's ability to pump blood. We hypothesize that exercise training or pioglitazone (Actos) will improve fat and sugar metabolism in the hearts of HIV+ people with The Metabolic Syndrome. This study will advance our understanding of cardiovascular disease in HIV+ people, and will test the efficacy of exercise training and pioglitazone for improving insulin resistance, heart metabolism and heart function in this at risk population.
Ritonavir-boosted protease inhibitor (PI) regimens have become a backbone for treatment of people with HIV. However, adverse drug effects, particularly lipodystrophy/lipoatrophy are closely associated with these regimens. Therefore, there is a need for a drug with comparable effectiveness to the ritonavir boosted PIs without the side effects of dyslipidemia, which has been associated with elevated cholesterol and cardiovascular disease Raltegravir is an HIV integrase inhibitor in phase III clinical development. To date there are no approved drugs that target the same stage of the HIV-1 lifecycle. However, data from studies indicate that raltegravir is generally safe and well tolerated and has strong antiretroviral activity when used in combination with licensed antiretroviral medications. This study aims to demonstrate that patients substituting raltegravir for a PI or NNRTI based antiretroviral regimen will be associated with a 10% reduction in body fat over 24 weeks. The study will consist of a total of 10 subject visits over a period of 48 weeks. Approximately 40 female patients will participate in this study (approximately 10 at UCLA).
A prospective, randomized, open-label pilot study to assess virologic suppression and immunologic recovery associated with a two-drug antiretroviral regimen of Raltegravir and the protease inhibitor lopinavir/ritonavir (LPV/r) and a three drug regimen with Raltegravir and two nRTIs (emtricitabine/tenofovir) in HIV-1 infected treatment-naïve subjects. Immunology Substudy added to determine the kinetics of recovery of CD4 T cells and subpopulations (regulatory T cell [T regs], TH-17 and TH1) after treatment initiation with Raltegravir based regimens and their relationship with functional CD8 T cells and if Raltegravir containing therapies leads to decreases in markers of gut microbial translocation and of cellular and soluble markers of immune activation.
This study will evaluate the effectiveness of an interactive virtual environment computer game in reducing risky sexual behaviors among men who have sex with men.
This study will evaluate whether childhood experiences are related to current sexual behavior of adult women.
The overall aim of the project is to evaluate rifabutin (RBT) as a replacement for rifampicin (RMP), for the combined treatment of tuberculosis and HIV infection. RBT represents an alternative to RMP for HIV infected patients as its half-life is longer and the enzymatic induction effect appears to be less important on the associated antiretroviral therapy (ART) drugs. This phase II trial is to determine precisely the pharmacokinetics parameters of RBT in combination with different ART regimens in Vietnamese HIV infected patients with pulmonary tuberculosis, in order to define optimal doses that will be further tested in a larger phase III trial comparing safety, tolerability and efficacy of RBT and RMP regimens.
To demonstrate that patients treated with Kaletra have an improvement in their quality of life compared to the quality of life they had with their previous NRTI therapy.
Metabolic changes commonly occur in HIV therapy. The purpose of this study is to assess the impact on insulin sensitivity from the administration of tenofovir disoproxil fumarate 300 mg compared with placebo in non-HIV-1 infected healthy adult males. Additionally, endothelial function, adipocytokines and lipids will be monitored.
This study will compare the effectiveness of brief versus detailed HIV counseling sessions, paired with referrals to either HIV-specific medical care or usual care, in reducing HIV risk behavior and in increasing treatment adherence in Uganda.
