Active clinical trials for "Acquired Immunodeficiency Syndrome"

The advances in treatment to prevent maternal HIV transmission to neonates have been groundbreaking. As a result, the number of new perinatally-infected children in the U.S. is now small. Subsequent improvements in the treatment of HIV-infected infants and children have been equally remarkable, ensuring that most previously infected American children have survived and are approaching adolescence. In addition, the number of HIV-infected adolescents worldwide is growing substantially in both resource-poor countries and in countries with increasing levels of health care. Therefore, there is a global cohort of children who have been living with HIV infection since birth who are aging into adolescence. Little is definitively known about the impact of HIV infection and its treatment on the maturation process in these children. AMP is a prospective cohort study designed to define the impact of HIV infection and antiretroviral therapy on pre-adolescents and adolescents with perinatal HIV infection. Domains to be investigated include growth and sexual maturation, metabolic risk factors for cardiovascular disease, cardiac function, bone health, neurologic, neurodevelopment, language, hearing and behavioral function, and sexually transmitted infections (STI).

A research study to evaluate the effect of aging and HIV on neurocognitive dysfunction (declining ability to process information), physical frailty and heart disease. HIV-infected participants whose virus is controlled on antiretroviral medications will be studied to determine the rates and risk factors of developing these conditions.

The aim of the study is to observe the tolerability and effectiveness of Kaletra in Human Immunodeficiency Virus/Hepatitis-B Virus and Human Immunodeficiency Virus/Hepatitis-C Virus co-infected patients.

The MTN-003 HIV prevention study include the use of microbicides, substances that kill microbes, and tenofovir disoproxil fumarate (TDF) and emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) - oral, FDA-approved, anti-HIV drugs. The purpose of this study is to determine if taking daily TDF and FTC/TDF as a part of the study MTN-003 has an effect on bone mineral density (BMD).

The purpose of this study is to examine the postprandial (anytime after a meal) effect of different dietary fats on endothelial function in HIV-infected and HIV-uninfected men.

Tenofovir (TDF)-containing regimens may be associated with decreasing renal function in HIV-infected patients concurrently treated with boosted PI's and/or have co-morbid conditions including diabetes mellitus, hypertension, anemia, hepatitis B, and hepatitis C.

Despite effective ART that can suppress both HIV and HBV, HBV-related liver disease remains a significant co-morbidity in this population. Little is known about the histologic spectrum of liver disease, the significance of complete vs. incomplete HBV suppression, the utility of novel virologic and serum markers of disease severity, and the long-term renal and bone effects of TDF-based therapy. This proposal will address these important questions and impact the science and health of those coinfected with HBV-HIV.

The purpose of this study is to assess the safety data of etravirine in a natural clinical practice.

Cryptococcal meningitis is one of the most common central nervous system infections among HIV-infected patients. The outcome is generally severe. This study aims to determine long-term survival rate among HIV-infected CM patients in the era of antiretroviral therapy (ART). The secondary objectives are to clarify outcomes of CM and determine prognostic factors.

Background: - The human immunodeficiency virus (HIV) causes acquired immune deficiency syndrome (AIDS). Combination antiretroviral therapy (ART) drugs treat HIV infection. They generally decrease the amount of HIV virus in the blood (called viral load) to very low levels. This happens only if the drugs still fight HIV and if taken every day exactly as prescribed. When not taken as directed, or if the ART drugs are not strong enough, the virus can become resistant to them, and the ART will not work to control the virus. Researchers want to know how to control HIV in people who can t lower their viral load with their current ART drugs. Objective: -<TAB>To better control HIV in people who can t get a lower viral load even with ART drugs and to learn more about why the HIV is not under control. Eligibility: People at least 18 years old and with HIV. People who have been on at least two combinations of ART drugs (including current ART). People whose last two viral loads were greater than 1,000 copies/mL. Design: Participants will be screened with medical history, physical exam, and blood tests. Participants will then have a baseline visit. They will have another physical exam, blood tests, plus answer questions about what they know about HIV and ART, and how they take their ART. Participants will arrange to stay in the NIH hospital for 7 8 days. They will take their medications as usual. At the time to take the ART drugs, they will have to ask a nurse to bring them. If they forget, the nurse will bring them. Participants will meet with a doctor, pharmacist, social worker and nurse to discuss ways to help participants remember to take their drugs. Participants will have blood drawn about every other day. Researchers will study the test results. Some participants will be put on different ART drugs. If that happens, participants will have another NIH hospital stay for 7-8 days. Participants will have 4 follow-up visits over 12 weeks, then every 3 months for 2 years or more.
