View clinical trials related to Human Immunodeficiency Viruses.
Filter by: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.
To test blood specimens using a new investigational test that detects antigen and antibody to human immunodeficiency virus (HIV). Results will be compared to an approved HIV antibody test and supplemental testing performed to determine HIV status.
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.
