Filter by:Recent studies suggest that HIV patients are at increased risk for cardiovascular events; however, the mechanisms underlying this increased risk remain unclear. Our group was one of the first to demonstrate that HIV infection is independently associated with accelerated atherosclerosis, as measured by carotid artery-intima media thickness (IMT), and that HIV-associated inflammation may be driving this accelerated atherosclerosis. The mechanism by which HIV disease independent of any drug-specific toxicity increases the risk of cardiovascular disease during HAART is not known. We hypothesize that even well controlled HIV infection is independently associated with cardiovascular risk and that further decreasing HIV-associated inflammation adding newer antiretroviral agents will also decrease cardiovascular risk. We will perform a small clinical trial of approximately 50 HIV-infected patients each to study the relationship between HIV infection, inflammation, thrombosis, atherogenic lipoproteins, and measures of atherosclerosis. We propose the following specific aims: Aim 1: To determine the influence of traditional and novel markers of inflammation on endothelial function and IMT progression; Aim 2: To determine if "intensification" with raltegravir in subjects on long-term antiretroviral therapy with clinically undetectable HIV RNA levels will improve endothelial function, and to determine if this effect is mediated by alterations in inflammatory markers, lipoproteins and/or thrombotic factors. For Aim 2, subjects from 2 randomized, double-blind, placebo-controlled raltegravir intensification studies will be asked to co-enroll in this cardiovascular study.
The goal of the proposed study is to use the HBV vaccine as a model for a future HIV vaccine trial, examining the efficacy of community-based outreach intervention as well as an accelerated vaccine schedule as a method for increasing acceptance/adherence with HBV vaccination protocols among not-in-treatment drug users. This study will also examine the effect of HBV vaccination coupled with community-based outreach intervention on reducing the incidence of HIV, HBV and HCV infections and the frequency of needle use and sexual risk behaviors related to these viral transmissions. A secondary purpose will be to assess the antibody response after HBV vaccination as a measurement of immunological response in drug users.
The purpose of this study is to determine the influence of posaconazole on unboosted fosamprenavir pharmacokinetics, and vice versa, in healthy volunteers.A second objective is to determine the safety of combined use of fosamprenavir with posaconazole in healthy volunteers.
To evaluate the single dose relative bioavailability of GSK1265744 10mg administered in either oral solution fasted, two 5mg tablets fasted, or two 5mg tablets following a moderate meal.
The U.S. Department of Health and Human Services (HHS) guidelines recommend that HIV infected patients who have never received anti-HIV therapy be treated with a triple drug regimen. The most commonly prescribed and successful regimen contains the medication efavirenz (EFV). However, this regimen may not be an option for everyone, hence alternative regimens are needed. This study was designed to look at how well different combinations of anti-HIV drugs work to decrease the amount of HIV in the blood (viral load) of and allow immune system recovery in people who have never received anti-HIV therapy. This study also examined drug tolerability and safety for the various drug combinations.
Infection with human immunodeficiency virus (HIV) causes decline in immunity or the ability to fight infection and progresses to acquired immunodeficiency disease (AIDS). Anti-HIV drug treatment has improved the prognosis of persons with HIV infection, but is expensive and potentially toxic. Low micronutrient levels occur in the blood even in early stages of HIV infection and increase risk of a poorer prognosis, but the role of micronutrient and antioxidant supplements in medical management of HIV/AIDS is not well defined. The proposed clinical trial aims to assess if supplementation of untreated HIV-infected adults with a micronutrient and antioxidant preparation can delay decline in immunity or disease progression or start of anti-HIV drug treatment compared with supplementation with standard multivitamins. If the findings are positive, the study has implications for health and health care savings.
The purpose of this study is to determine whether fish oil supplementation with Lovaza, formally known as Omacor will result in a significant reduction in serum triglyceride (TG), an increase in high density lipoproteins(HDL), and an improvement of endothelial dysfunction.
This study will enroll completers of a prior 24 week MEMS cap study of Kaletra adherence, conducted in 2005 - 2006, and repeat the MEMS monitoring for an additional 24 weeks in 2008/2009 on the current antiretroviral anchor drug. The goals of the study are to correlate long-term adherence with virologic outcome, and to explore the stability of MEMS cap adherence measurements over time.
A phase Ib partially blinded pilot study to evaluate the safety and immunological effects of PENNVAX-B with or without co-administration of constructs containing DNA encoding for the expression of either IL-12 or IL-15. Primary objectives 1. To determine the safety of HIV-1 DNA constructs (PENNVAX-B). 2. To determine the safety and optimal doses of the IL-12 and the IL-15 adjuvant constructs when given with PENNVAX-B. Secondary objectives 1. To compare the various vaccine groups for their immunological responses to several HIV-1 antigens, utilizing the ELISPOT assay. 2. To analyze antibody responses to the vaccine antigens over time. 3. To measure CD8 cell proliferative responses to vaccine antigens over time.
This is a pharmacokinetic, descriptive, open-label, prospective, multicentric, national study in Aids and tuberculosis co-infected patients, to be laboratory and clinically monitored during the treatment with lopinavir-ritonavir and rifampin medications. Study population: Thirty patients older than 18 years, both male and female, which present active tuberculosis and failure or contraindication for any motive to an efavirenz will be selected to participate in the study. Objectives: - Evaluate the pharmacokinetics of lopinavir-800mg / ritonavir-200mg combination (every 12 h) in association with rifampin-containing anti-tuberculosis regimens, in patients presenting tuberculosis and HIV-infected with indication to antiretroviral treatment according to Brazilian Ministry of Health's guidelines, with contraindication to the use of NNTRI. - Describe the adverse events observed during the tuberculosis treatment period with rifampin associated with antiretroviral therapy consisting of lopinavir-800mg / ritonavir-200mg every 12 hours. - Describe clinical, immunological and virological endpoints throughout the study with these drugs.
