Filter by:Tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) are two antiretroviral medications used for the treatment and prevention of HIV/AIDS. This study will examine how these medications are processed in the body of people who are HIV-infected, as well as in people who are HIV-uninfected.
This pilot study aims to study gut B cells in HCV+HIV+, HCV+HIV-, HCV-HIV+, and HCV-HIV- volunteers. Volunteers will undergo a screening blood draw and flexible sigmoidoscopy with biopsy.
To estimate the incidence of H1N1v influenza-like illness and to study the risk factors for serious influenza forms during pandemic period in French HIV infected patients. - Definitions: - Influenza like illness is defined as fever> 37°8C and cough or pharyngalgia. (Centers for Disease Control definition). - Serious forms of influenza-like illness is defined by hospitalization within 14 days onset of symptoms or death attributed to influenza like illness. - Design: - Survey sampling for estimating H1N1v influenza-like illness incidence. - Out of approximately 50 000 patients under follow-up in one of the 40 ANRS centres, a sub-group will be selected by random sampling. Sampling will be stratified by centre and sampling fraction per site will vary in order to select 60 to 80 patients for this study per site. A total of 2500 to 3000 patients will be selected to allow for estimating the incidence of H1N1v influenza-like illness with an adequate precision. Selected patients will be asked to contact the clinical staff on site as soon as any influenza like symptoms appear. In the case of influenza like illness patients are requested to attend to the clinic within 24 hours for physical examination and naso-pharyngeal swab for diagnosis of A(H1N1)v infection. Nested case-control study for the determination of risk factors for serious forms: - Cases: Serious forms (see definition above) identified by any clinical site or hospitalisation unit. - Controls: Patients of the randomly selected sample (see survey sampling above), presenting with influenza-like illness without any criterion for severity. Exhaustivity check: The exhaustivity of symptomatic forms will be assessed a posteriori by merging information from all available data sources.
The main goal is to confirm, among HIV1-infected patients, data from in vitro studies showing that antiretroviral therapies induce an accelerated aging through the same mechanisms than genetic laminopathies or than "physiological " aging, that is through the synthesis and persistence of farnesylated prelamin A. The secondary goal is to measure the impact of HIV infection and of antiretroviral therapies on markers of cell ageing (proteasome, mitochondria, telomere). The perspective is to fix antiretroviral therapy side effects using the same drug combination that will be used in few weeks in Marseille to treat children suffering from progeria
HIV-1 cannot be eradicated from infected individuals by current antiretroviral regimens. Cellular reservoirs and tissue sanctuary sites allow latent HIV-1 persistence and ongoing low-level virus replication. This project aims to characterize the residual replication of HIV-1 in subjects on antiretroviral therapy, particularly in the gut-associated lymphoid tissue.
This study will examine whether a computerized, self-administered assessment of patient medication adherence and health behaviors, plus support for adherence, improves the ability of clinicians to identify adherence problems and leads to better adherence.
The lack of success in treating substance abuse may be contributed to by a limited understanding of the clinical neurobiology of drug abuse. A better understanding of such deficits might aid in the development of more relevant pharmacological and psychosocial treatment approaches. Thus, the purpose of this study is to test the hypothesis that repetitive illicit drug use may be associated with cortical and subcortical structural abnormalities, vascular abnormalities, as well as neuropsychological decrements. Additionally, a battery of psychological tests are administered to provide information about demographics, drug use, neurocognitive measures, and personality structures....
The purpose of this trial is to assess the impact of raltegravir, maraviroc, darunavir/r, and Truvada® (emtricitabine/tenofovir) vs. darunavir/r and Truvada® on cell-associated HIV-DNA levels in patients with primary HIV-1 infection.
This study has been designed to evaluate the performance of the Chembio Diagnostics Systems, Inc. DPP® HIV 1/2 rapid test. The device is intended to qualitatively detect the presence of antibodies against HIV-1/2 in oral fluid, whole blood (capillary and venous), serum or plasma. This study will assess the DPP® HIV 1/2 Screen assay's ability to detect HIV-1.
This is a phase III, randomized, controlled, open label study with two vaccine regimens. The study will assess the relative safety and immunogenicity of vaccine regimens comparing adjuvanted versus non-adjuvanted formulations of A(H1N1) inactivated influenza virus vaccine in subjects with Human Immunodeficiency Virus Type 1 (HIV-1) Infection and to compare safety and immunogenicity data with a contemporaneously enrolled control group of age-comparable, healthy subjects. Because certain individuals may be hypo-responsive to influenza vaccination, additional studies with high-risk groups are warranted in order to determine the optimal vaccine formulation and dosing schedule for prevention of novel H1N1 virus infection.
