Filter by:The main aim of the study is to investigate the combined effects of using anabolic steroids and protease inhibitors on fat metabolism and body composition of People Living with HIV/AIDS. We are seeking to answer the following questions: 1) Are there any significant differences in serum blood lipids, lipodystrophy, in persons with HIV taking antiretroviral therapies and anabolic steroids versus antiretroviral therapies alone?
Lactic acidosis is a potentially life-threatening disease associated with the treatment of chronic HIV infection. Although acidosis is rare, hyperlactatemia is common and may have long term consequences yet to be recognized. Lactic acidosis is a manifestation of mitochondrial toxicity; consequences which have yet to be fully recognized and understood. In this study, we propose to look at lactate clearance and production by two methods, in four treatment groups, including HIV positive subjects on highly active antiretroviral therapy (HAART) treatment regimes and without HAART regimes, with liver steatosis and without, and compared with HIV negative controls. Supplementation with cofactors thiamine, niacin and L-carnitine, which may have a positive effect on lactate metabolism by facilitating mitochondrial function, will be studied as well.
The "Adult Antiretroviral Treatment and Resistance Study," hereafter referred to as "The Tshepo Study," is the first large-scale research study of antiretroviral therapy to treat AIDS and HIV infection in Botswana. The Tshepo Study is an open-label, randomized study comparing: (1) the rate of development and specific types of drug resistance mutations with various antiretroviral combination therapies to HIV-1C, the subtype of HIV found in southern Africa, and (2) the short and long-term effectiveness of two operational modifications of Directly Observed Therapy (DOT) medication adherence strategies for antiretroviral therapy. Specifically, treatment follow-up via the Standard of Care, the national standard of care as it evolves in Botswana, with intensive clinic-based follow up including regular adherence education sessions, will be compared to Community-Based Directly Observed Therapy (Com-DOT). Com-DOT involves the SOC with added community or family-based DOT. This Com-DOT component would involve a trained, community or family-based Medication Partner ("mopati") who observes the patient take his or medications daily.
The goal of the project is to examine the impact of providing housing for people living with HIV who are homeless or at imminent risk of homelessness on their HIV disease progression, risks of transmitting HIV, and medical care access and utilization.
The study is a 3-year, randomized trial to compare ART delivery through two different models: a) ART delivered through health facilities by clinically qualified staff and b) home-based care in which lay workers, i.e. non-medically qualified people, play a major role in the ART delivery and clients are followed up at health facilities less frequently. The primary objective is to measure the effects of these strategies on HIV viral load. We will also examine the effects on treatment failure, disease progression, survival, adherence, family member HIV testing, sexual behavior, and cost-effectiveness.
Plasmodium falciparum malaria and HIV are among the most important infectious diseases in sub-Saharan Africa. Approximately two-thirds of the estimated 35 million HIV infected persons live in sub-Saharan Africa. Of the 300-500 million annual cases of malaria infection occurring worldwide, about 90% of P. falciparum infections occur in sub-Saharan Africa, resulting in approximately 1 million deaths, mostly in children under five years of age. It is clear that HIV and malaria are responsible for substantial disease, suffering, and an enormous economic burden on the people who can least afford it. Although a study in 1993 in Tanzania showed significantly higher prevalence of malaria infections in HIV-positive compared to HIV negative adults, until recently there have been few studies showing any association between the two infections. We conducted a study to measure the efficacy of the then-first line antimalarial drug (sulfadoxine-pyrimethamine) among patients in three study arms: those who were HIV negative, those who were HIV infected with CD4 cell counts < 200, and among HIV infected patients with CD4 cell counts >= 200. Our hypothesis is that patients with HIV infection and low CD4 cell count will not respond to antimalarial therapy as well as patients who are HIV infected with higher CD4 cell counts or who are HIV negative.
The purpose of this study is to try a known antiretroviral combination in HIV- infected children with only one intake a day, in order to simplify the prescription and improve adherence to treatment. This is what is called a phase II clinical trial, only recruiting and following a small number of children (50) during one year to evaluate the quantity of drug in the blood just before it is taken and one to three hours after it is taken. The other important objective is to study the tolerance of drugs in that mode of prescription of the triple combination.
The purpose of this study is to evaluate whether a therapy with an all once daily regimen of efavirenz (EFV), didanosine (ddI)-EC and lamivudine (3TC) leads to improved outcomes, as measured by viral load, CD4 counts, adherence, safety, and tolerability.
The purpose of this study is to compare long-term safety and tolerability of stavudine (d4T) extended release (ER) versus conventional (immediate release [IR]) formulations, each in combination with lamivudine (3TC) and efavirenz (EFV) in subjects who have completed Bristol-Myers Squibb (BMS) studies AI455-096 and AI455-099.
The purpose of this study is to evaluate whether a therapy with an all once daily regimen of stavudine extended release (d4T XR), lamivudine (3TC), and efavirenz (EFV) leads to improved outcomes, as measured by viral load, CD4 counts, adherence, safety, and tolerability.
