Filter by: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 primary purpose of the study is to investigate the safety and efficacy of KP-1461 given every 12 hours for 124 days to HIV+ patients who have failed multiple antiretroviral regimens.
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]).
The purpose of this study is to develop and evaluate a brief clinic-based culturally tailored smoking cessation treatment for a largely low-income, Latino, HIV+ population. We will compare this Culturally-Tailored Intervention (CTI) that incorporates a strong social support component and is targeted to the special needs and concerns of a Latino population to a Standard Care Intervention (SCI) control condition, in a randomized controlled trial. We hypothesize that those Latinos receiving the CTI will demonstrate greater biochemically verified smoking abstinence rates at 12-months post-baseline than those receiving the SCI control treatment. All study participants and their participating social supports will be offered use of the nicotine patch.
This study will compare the effectiveness of two different approaches to providing routine HIV counseling, testing, and referral services in an urban hospital emergency department setting.
