The aim of this study is to establish a clinical score panel based on clinical, molecular and genetic parameters that allow us to stratify and obtain an early detection of patients with an increased risk of developing hepatocellular carcinoma (HCC).
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.
The purpose of the study is to compare the efficacy, safety and tolerability of darunavir/ritonavir 800/100 mg once a day (O.D.) as a monotherapy versus a triple combination therapy containing 2 nucleosides and darunavir/ritonavir in 250 HIV-1 infected patients who have been on Highly Active Antiretroviral Therapy (HAART) and have plasma viral load below 50 copies/ml for at least 24 weeks.
