Filter by:To assess the safety of dapivirine (25 mg) administered via a silicone vaginal ring in HIV-uninfected adolescent females, when inserted once every 4 weeks during 24-week of study product use.
This study will evaluate the safety of the dapivirine vaginal ring when inserts once every 4 weeks in postmenopausal women over 12 weeks of product use.
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.
It is estimated that over 1 million people in the United States have HIV infection. While HIV is treatable, there are still high rates of HIV-associated neurocognitive disorder (HAND). HAND is defined by low scores on memory testing. To meet the criteria for HAND, an HIV-infected individual has to have a low score on at least two different memory tests. It is estimated that 20-50% of people living with HIV have HAND. It is therefore still a common problem. While individuals with HAND typically improve on antiretroviral therapy for HIV, often this improvement is incomplete. Also, there are over 20 antiretroviral medications approved for HIV in the US. It is not clear if the specific choice of antiretroviral medication makes a difference in the improvement of HAND. The investigators have designed a small preliminary study in which subjects with and without HAND who have never been on treatment for HIV or have been off treatment for at least 6 months are followed for the first 12 months after starting antiretroviral therapy.The investigators will enroll a maximum of 46 subjects (23 subjects in each arm). Subjects will also be followed by their primary HIV medical provider. For the study, subjects will be followed for 48 weeks. There are three followup visits: 12 weeks, 24 weeks, and 48 weeks. Memory testing will be performed at baseline and each followup visit. Blood will also be taken at baseline and the three followup visits to measure changes in inflammation. A lumbar puncture will be performed at baseline and at 24 weeks to measure changes in inflammation and amount of HIV virus in the spinal fluid. There is also an optional lumbar puncture at the last study visit of 48 weeks
The purpose of this study is to determine the safety, pharmacology and bioactivity of disulfiram in antiretroviral treated HIV-infected adults. The investigators primary hypothesis is that 3 days of disulfiram will result in an increase in HIV transcription in CD4+ T-cells in patients on suppressive antiretroviral therapy (ART).
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 compare the liver toxicity in HIV-infected patients with chronic hepatitis B and/or hepatitis C, who start a new antiretroviral drug regimen, as well as the influence of the degree of pre-existing liver fibrosis on the incidence of liver toxicity.
A proof of concept study to evaluate the feasibility of using the Shang Ring, a novel male circumcision device across all childhood age groups namely infants (under 1), 1-5 age group, 6-12 age group and the 13-17 age group. The study will evaluate the safety, efficacy and course of wound healing when using the Shang Ring technique across the four childhood age groups.
To address the question of the comparison of two courses of Vivitrol with differing lengths in 130 HIV negative, consenting, opioid addicted patients who have completed inpatient treatment. Participants will be randomized under double blind conditions to a 24 or 48-week course of pharmacotherapy, along with bi-weekly drug counselling, over 48 weeks, with follow-ups at weeks 60 and 72. The 24-week cohort will receive Vivitrol placebo injections in weeks 24 to 48.
This pilot single arm, single site, open-labeled switch study seeks to enroll thirty (30) HIV positive patients infected with CCR5 tropic virus that have achieved an undetectable viral load on a non-Selzentry®-containing regimen [Protease Inhibitor (PI)/Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI)/Integrase Inhibitor plus 2 Nucleoside Reverse Transcriptase Inhibitor (NRTI)] and switch them to once-daily Selzentry® (600mg qd) plus the same 2 NRTIs.
