Filter by:In retrospective studies, acceleration of hepatic fibrosis has been seen in Nevirapine (NVP) treatment when compared with Protease Inhibitors (PI) boosted with ritonavir treatment in patients with Human Immunodeficiency Virus (HIV) and Hepatitis C Virus (HCV) infection. The high incidence in our country of HIV-HCV co-infection, the availability of a new Kaletra (LPV/r) formulation (more convenient and better tolerated than soft capsules) as well as the possibility of analyzing hepatic fibrosis evolution in a fast and bloodless way, make attractive a study that, in a prospective way, could check the benefits of substituting NVP by LPV/r on hepatic fibrosis in this community.
This study focuses on collecting and analyzing quantitative data related to adherence to antiretroviral treatment from patients in Dali, China, over a one-year time-frame and generating preliminary data on an intervention designed to improve adherence to antiretroviral treatment among the study population.
The HIV integrase inhibitor, raltegravir (RAL), which was recently approved by the FDA, has been shown in several trials to be highly effective. The purpose of this trial is to estimate the viral load decay rate in treatment-naive HIV infected participants receiving RAL and emtricitabine/tenofovir disoproxil fumarate (FTC/TDF).
Human immunodeficiency virus/Hepatitis B virus (HIV/HBV) co-infections are frequently observed due to shared routes of transmission, with reported figures indicating 6-9% of HIV-infected individuals in developed countries are chronically infected with HBV. HIV infection impacts on the natural progression of HBV infection, increasing levels of HBV replication and the risk of liver-associated mortality. Liver diseases associated with HBV are affected by the antiviral drugs used for HIV infection (toxic side effects), the current immune function in the patient, by improvements in the immune system brought about by control of the HIV infection, and by the development of resistance to the antiviral agents used for both the hepatitis B and the HIV infection. Tenofovir (TDF) is a newer antiviral drug that is frequently used for HIV infection and is also highly active against hepatitis B; however it is still unknown whether resistance to TDF will eventually develop and how this will affect the long-term outcomes
Current management of HIV infection includes anti-retroviral therapy (ART). ART cannot cure the infection, making it a life-long treatment that requires sustained patient compliance and imposes significant individual and societal financial burdens on healthcare services. Furthermore, ART side effects often require medication that increases the inconveniences and financial burdens of HIV management. Of further concern is the emergence of viruses resistant to ART that can result in treatment failure. ART-free periods could provide substantial benefit. Vacc-4x is a peptide-based HIV immunotherapy that is proposed for prolongation of ART-free periods. The purpose of this study is to determine whether Vacc-4x immunotherapy can give safe ART-free period.
Infections with HIV-1 group O are found in 1 to 3 % of persons living with HIV in Cameroon. The natural history and treatment response is not well understood. The natural resistance to non nucleoside reverse transcriptase inhibitors and their possible low sensitivity to protease inhibitors complicate the choice of an adequate treatment options. This observational study is aimed at evaluating the antiretroviral treatment response of HIV-1 group O infected patients in comparison with HIV-1 group M infected patients. The proposed standardized follow-up will facilitate a better understanding of the natural history and treatment specificities to improve the patients management. This is a non randomized study, open label, with standardized follow-up. A total of 171 patients
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).
The purpose of this study is to determine whether cognitive behavioral therapy (CBT) is effective in the prevention of depression during interferon and ribavirin treatment for hepatitis C infection.
