Active clinical trials for "Acquired Immunodeficiency Syndrome"

The purpose of this study is to reduce the HIV/HCV incidence among the clients attending community-based methadone maintenance treatment (MMT) , and to prevent the secondary sexual transmission from HIV+ clients to their spouse and sex partners, through intensified comprehensive intervention.

This study will look to see if there are changes in the blood cells that are associated with bone disease and sort out effects that are due to the HIV virus itself, the medications and see if faster aging occurs in the cells of HIV infected persons. Bone disease will be measured by a special X-ray called a DEXA scan. A DEXA scan is used by doctors to see if someone has normal bone mass for their age or if there is thinning of the bones. The purposes of this study are: to learn how common bone disease is in HIV infected patients over the age of 50 years that receive their care at the CORE Center to see what are the common causes of bone disease in older HIV infected persons to see if there are differences in blood cells and levels of cytokines in patients who do or do not have bone disease, as this may help researchers determine the cause of bone disease.

The purpose of this study is to investigate T-cell mediated immune responses to HIV-1 and HCV and determine how these responses are affected by HCV treatment and correlates to response. Furthermore, to study Interferon-inducible protein-10 (IP-10) dynamics during HCV treatment, and correlate this to treatment outcome.

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

The purpose of this research study is to learn about levels of antiretroviral drug levels and response to HIV virus in the genital tract of women who are post-menopausal. The investigators in this study think that the levels of hormones post-menopausal HIV-infected women may have in their bodies may affect the levels of antiretroviral drug, and therefore affect how much HIV virus they have in their bodies. Since women who have already gone through menopause have different levels of hormones, such as estrogen, than women who are pre-menopausal, the investigators would like to check the levels of antiretroviral drugs in their blood, their genital secretions, and their genital tissue.

This study is a cross sectional observational study to evaluate the prevalence of HLA-B*5701 in the major French ethnotypes. Any HIV-1 infected subject will be eligible for this study including antiretroviral therapy (ART) naÃ-ve and experienced subjects irrespective of abacavir use, as well as subjects previously tested for HLA-B*5701. Subjects will be approached during a standard clinic visit, and all subjects will be consented prior to any study specific procedure. Subjects will be asked to provide a tissue sample (cheek cells and blood sample) which will be used to assess HLA-B*5701 status by central and local methodologies.

The purpose of this study is to understand the effects of decreased functioning of the testes or ovaries on mental performance in males and females using illicit drugs excluding marijuana.

This is a long-term follow-up study of people who are identified during acute or recent HIV infection and are being followed at clinical research sites associated with the Acute HIV Infection and Early Disease Research Program (AIEDRP).

While most people with HIV experience significant destruction of their immune systems, some people appear to have preserved immune function and can control the virus without drugs. Early treatment with anti-HIV drugs may help preserve the immune system, allowing it to control the virus once the drugs are stopped. This study will evaluate the immune system response of HIV infected people who are treated with anti-HIV drugs soon after being infected.

To define the incidence and prevalence of AIDS-associated cardiomyopathy. Also, to conduct immunopathology and serologic studies in endomyocardial biopsies and autopsy tissues.
