Filter by:A new approach to HIV prevention currently being studied includes the use of topical microbicides and orally administered anti-HIV drugs. The purpose of this study is to better understand the impact of microbicides in women who are diagnosed with HIV-1 during participation in previous microbicide trials.
The purpose of this study is to evaluate antiretroviral activity of up to five different oral doses administered for two weeks of bevirimat versus placebo in HIV treatment experienced patients, who have documented genotypic resistance to at least one major mutation from the IAS-USA list (2007)of resistance mutations for NRTIs, NNRTIs, or PIs. Patients will also be monitored for side effects, and the pharmacokinetics of bevirimat will be determined.
Study Hypothesis: Do certain risk behaviours impact/predict levels of HIV antiretroviral adherence? Objectives: - To assess risk behavior in HIV-positive individuals receiving highly active antiretroviral therapy.(HAART) - To assess levels of adherence in the same subjects at the same time point - To determine if there is a correlation between HAART adherence and risk behaviour
This study aims to look at the safety and tolerability of immunization with dendritic cell vaccine prepared using the patient's own cells and virus. It also aims to explore the virologic efficacy of the vaccine as determined by a decrease in the viral load 12 weeks after analytic treatment interruption.
The study has been designed to test the hypothesis that in patients co-infected with HIV and HCV who exhibit maximal virologic suppression on a double class antiretroviral (ARV) regimen, including two Nucleoside Reverse Transcriptase Inhibitors (NRTIs) and a Non-nucleoside Reverse Transcriptase Inhibitors (NNRTI) or a Protease Inhibitor (PI) (boosted or not with ritonavir), simplification of highly active antiretroviral therapy (HAART) to Kaletra® monotherapy will represent a viable strategy without any negative impact on the virologic control of HIV infection.
Abstract: Over 25 million HIV-1 infected individuals are currently living in Africa and as many as 50-90% may be co-infected with soil transmitted helminths such as roundworms, hookworms or whipworms. Helminth infection in HIV-1-infected individuals may increase HIV-1 RNA levels and increase the rate of progression of HIV-1 to AIDS. Studies have also shown that successful treatment of helminth co-infection (as documented by clearance of helminth eggs in stool) led to a significant decrease in HIV-1 plasma viral load (-0.36 log10). This change in viral load was significantly greater than that seen in those individuals without documented clearance of their helminth co-infection (+0.67 log10) (p=0.04). Studies conducted in Africa have shown an estimated 2.5-fold increased risk for sexual transmission of the HIV-1 for each log increase in plasma HIV-1 viral load. In addition to direct effects on plasma viral load, the rate of CD4 cell decline in helminth infected individuals may be directly impacted by the significant immune activation seen with such co-infection. The investigators propose a randomized controlled trial examining the potential benefits of routine empiric helminth eradication in HIV-1 infected adults who do not yet qualify for antiretroviral (ARV) therapy in Kenya. The current standard of care of symptomatic diagnosis and treatment will be compared to a systematic empiric scheduled de-worming program for HIV infected adults. The investigators will compare markers of disease progression including rate of CD4 decline and changes in HIV-1 RNA levels between the two treatment arms.
The development of a vaccine against HIV/AIDS has been primary focused on the structural proteins (Env, Gag) of HIV-1 with the aim of inducing sterilizing immunity by blocking virus entry. Alternative approaches are focused on new vaccine strategies aimed at modifying the virus-host dynamic favouring the establishment of a long-term non-progressing disease status. Such strategies target regulatory proteins that are the first to be expressed after infection and are essential for viral replication, infectivity and pathogenesis. Thus, this approach may be effective for both preventive and therapeutic vaccination strategies.
The purpose of this study is to identify biological markers, including genes, associated with sleep disturbance and other symptoms among people with HIV.
This trial is designed to assess the safety, tolerability, pharmacokinetics and viral kinetics after multiple infusions of bavituximab in patients co-infected with HCV and HIV.
The purpose of the study is to determine whether an abbreviated pretest/post-test CDC recommended counseling is as equally acceptable to prenatal patients as the standard strategy using prenatal care nurses and medical providers at San Francisco General Hospital [SFGH]).
