This is a research study to evaluate the safety of a vaccine to protect people from HIV infection. Human Immunodeficiency Virus (HIV) is the cause of AIDS (Acquired Immune Deficiency Syndrome). AIDS is one of the most serious viral infections of our time. It is believed that all persons who contract HIV will eventually develop AIDS. Because of this, we are trying to develop new ways to prevent infection with HIV. The vaccine that will be tested in this study has been prepared from a small part of the HIV. The part of the HIV used in this vaccine is the "envelope" or coating part of the virus. In this study, researchers will evaluate how well the vaccine is tolerated, how much vaccine should be given, and determine if any side effects occur in response to the vaccination.
The study is designed to evaluate interferon responses to CMV in HIV positive individuals and a component will look at interferon responses to CMV in HIV positive individuals over time after commencement of antiretroviral therapy. We will also look at the correlation between CD4 T cell numbers and HLA type with the interferon response.
In this study, an intervention is tested that is designed to reduced risky sexual behaviors in adolescent females. Study design: - randomized, controlled study - participants: 640 girls aged 15-19 years old - length of follow-up: 1 year after the intervention is completed Study hypothesis: The experimental condition will significantly reduce risky sexual behaviors in adolescent females as measured by: - lower incidence of STI's at 6 and 12 months, as compared to baseline - decreased incidence of risky sexual behaviors - increased knowledge of the level of risk of certain behaviors - increased knowledge of safer sexual behaviors that can prevention HIV infection - increased motivation to reduce sexual risk - increased behavioral skills to reduce risk of HIV infection
Patients with HIV an have a variable course of their infection. We are trying to identify factors which worsen or ameliorate the course of the disease. Such factors may be related to metabolism (breakdown) of drugs or to iron handling by the body.
Genital herpes is a long-life sexually transmitted diseases which infects a large proportion of women in Africa. Its clinical symptoms are painful sores on the genitals, which heals after a few days. HIV infection can worsen genital herpes. In turn, it is possible that genital herpes increases the quantity of HIV secreted at the genital level in women infected by the 2 viruses. This study is dedicated to verify this hypothesis.
Access to care and treatment using antiretroviral drugs will be expanded in Vietnam in the next few years. The ANRS 1210 study is a pilot program to evaluate the feasibility of a simplified antiretroviral treatment using three antiretroviral drugs once a day. The objectives will be to assess the efficacy and the tolerance of this treatment and to better understand the difficulties linked to social and behavioural conditions of patients at different stages during the treatment.
In the context of Sub-saharian Africa, this trial evaluate one of the most simple treatment available for HIV-1 infected patients. The combination proposed is a triple antiretroviral therapy with only one intake of 3 pills per day. This combination has already been studied in the North countries. Here in Senegal, the efficacy and the compliance to treatment will be evaluated after 24, 48 and 96 weeks of treatment.
The advent of new antiretroviral agents, in particular Highly Active Antiretroviral Therapy (HAART), spectacularly reduced HIV-associated morbidity and mortality. However, new complications have appeared in HIV-infected patients treated by with HAART such as dyslipidemia, insulin resistance, diabetes mellitus, and related cardiovascular complications including acute coronary syndromes, peripheral vascular disease, and stroke have been reported. A linear association has been proved between increased intima-media thickness of the common carotid artery (CCA-IMT), aortic stiffness (pulse wave velocity [aPWV]) and incidence of cardiovascular events suggesting that IMT and aPWV could be considered as an early marker of atherosclerosis. The progression of IMT has been shown to be predictive of cardiovascular events. Case control and longitudinal studies but not all have suggested an increase CCA-IMT in HIV-infected patients under HAART compared with non-HIV infected patients with different progression. The aim of this study was to examine the effects of pravastatin on CCA-IMT and aortic stiffness in dyslipidemic HIV-infected patients receiving HAART by using a high-resolution echotracking system. Patients in the pravastatin group were consecutively recruited in four department of infectious diseases if they fulfilled the following criteria : (1) HIV-infected treated with HAART for > 12 months 2) with dyslipidemia, defined as fasting serum LDL cholesterol > 160 mg/dL before initiation of pravastatin, (3) treated with pravastatin > 12 months and one more coronary risk factor. The patients in the control group were selected consecutively in the same departments among 1) HIV-infected patients treated with HAART > 12 months 2) fasting serum LDL cholesterol > 160 mg/dL 3) without lipid-lowering drugs and one more coronary risk factor. Cases and control patients were matched for age, gender and tobacco consumption. Using data from Mercie et al., inclusion of 42 patients in pravastatin and control groups was the minimum sample size needed for detection of a 6.5% difference in CCA-IMT, in a two-sided test (a = 0.05, b = 0.20). The protocol of the study, sponsored by the French Society of Cardiology was approved by the Committee for the Protection of Human Subjects in Biomedical Research of Pitié-Salpétrière University hospital in Paris. Written informed consent to participate in the study was obtained from each patient.
This laboratory-based substudy of an effectiveness trial of two Hepatitis B vaccines in HIV-negative youths is being done to evaluate the genetic contribution to the individualized immune response.
