Filter by:Background: Antiretroviral therapy has changed the natural history of the HIV infection in developed countries becoming a chronic disease. This clinical scenario would need a new approach to control patients, simplifying the follow-up visits and the accessibility to the healthcare professionals. A new home care model using a telemedicine system (Virtual Hospital) was developed.
The objective are to assess the nature and incidence of drug intolerance observed with a new antiretroviral triple therapy, Truvada® [0-0-1] + Isentress® 400 mg tablets [1-0-1], prescribed in a setting of the treatment of individuals with recent exposure to a risk of transmission of HIV infection and to compare the results with those of previous studies conducted according to the same methodology, with other combinations of antiretrovirals.
Project POWER will test the efficacy of a multi-session HIV Prevention program, adapted from an existing program (Project SAFE), for incarcerated women in the rural South.
The overall goal of this study is to study influenza vaccine responses in HIV infected individuals. Immunocompromised individuals require special protection from influenza, but may not respond appropriately to the standard killed vaccine. Patients who receive the H1N1 flu vaccine as part of their standard of care will be asked to donate blood samples for immunologic studies. These studies will determine whether participants were able to produce the appropriate antibodies to the vaccine and possibly identify predictors of vaccine responsiveness. Our hypothesis is that vaccine responsiveness to the new H1N1 influenza vaccine will be compromised in HIV infected patients.
Two previous studies of an HIV preventive vaccine, the STEP study and the Phambili study, were halted because people who received the vaccine were more likely to become infected with HIV. Why this vaccine failed is still being researched, but one reason may be related to the recombinant Adenovirus type 5 (rAd5) virus vector used in the vaccine. Two trials of another HIV preventive vaccine that used a rAd5 virus vector were conducted in Uganda. This study will obtain follow-up safety information on participants in those trials.
The purpose of the study is to look at the levels of three HIV medications: tenofovir, emtricitabine, and efavirenz in blood after the drug intake has been stopped in order to understand how long these drugs persist in the blood. The study will specifically look at blood levels of these three drugs (taken as a 3-in-1 tablet) after taking them every day for 14 days. This study is not randomised which means that all subjects will receive all study medications in the same order. You and the study doctor will know which study medications you are taking at all times during the study.
The purpose of this study is to examine how Buprenorphine, a form of opioid addiction treatment, changes the ability to think and reason among people addicted to opiates, who are either HIV negative or HIV positive. In addition, blood samples will be stored for HIV+ and HIV- individuals who take buprenorphine to study its effect. This study hypothesizes that the HIV positive participants will demonstrate significant improvement in thinking and reasoning ability at 3 and 6 months compared to baseline, but that their thinking and reasoning ability will still be lower than HIV negative participants. This study also hypothesizes the biomarkers in participants' blood samples will be associated with measures of change in thinking and reasoning ability.
The purpose of this study is to reduce the HIV/HCV incidence among the clients attending community-based methadone maintenance treatment (MMT) , and to prevent the secondary sexual transmission from HIV+ clients to their spouse and sex partners, through intensified comprehensive intervention.
This study is designed to evaluate the safety and efficacy of a regimen containing Cobicistat (COBI)-boosted atazanavir (ATV/co) plus emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) versus ritonavir (RTV)-boosted atazanavir (ATV/r) plus FTC/TDF in HIV-1-infected, antiretroviral treatment-naive adults. Development of COBI as a "pharmacoenhancer" could provide a beneficial alternative to RTV for use in combination with protease inhibitors.
HIV-uninfected children born to HIV+ women have low level heart problems at birth which may predispose them to heart failure, arrythmias and heart attack later in life. The impact of these heart problems on future heart health is unclear as it is unknown if heart problems in these children persist, worsen or resolve in pre-pubescence. The objective of this study is to characterize heart function in HIV-negative pre-pubertal children born to HIV+ women and exposed to HIV and HAART in utero and compare them to age and gender matched healthy children born to HIV-negative women. Through this objective we will determine if heart problems in HIV-negative children born to HIV+ women and exposed to HAART in utero persists, worsens, or resolves during pre-pubescence.
