Filter by:The purpose of this study is to find the best tests to use to investigate the differences between older and younger people with HIV disease. Test to be included will measures of memory, learning, activity levels, sleep patterns, emotional well-being and sexual health.
Improvement in the rate of bacterial translocation may lead to a decrease in a chronic inflammatory response thereby decreasing CD4 destruction and HIV proliferation. By the addition of probiotics we hope to show a reduction in LPS leading to a decrease in chronic inflammation and therefore an improvement in immune markers.
Purpose: To see how growing older changes the amount of HIV drugs in the blood of HIV-infected men and women. Many changes happen in the body as it ages that may affect the way drugs are carried in the blood, broken down or removed from the body. This study will look at the amount of drug in the blood and cells of the immune system for patients taking efavirenz, tenofovir and emtricitabine or atazanavir boosted with ritonavir, tenofovir and emtricitabine. Participants: The population will comprise of 56 (6 for intensive PK and 50 for sparse sampling) HIV-infected adults currently adhering to an antiretroviral regimen containing efavirenz with tenofovir and emtricitabine and the same number and distribution of HIV-infected adults currently adhering to an antiretroviral regimen containing atazanavir boosted with ritonavir with tenofovir and emtricitabine. Procedures (methods): This study will be completed at the University of North Carolina at Chapel Hill. There will be four groups of subjects: Efavirenz/tenofovir/emtricitabine Group A, Efavirenz/tenofovir/emtricitabine Group B, Atazanavir/ritonavir/tenofovir/emtricitabine Group A, and Atazanavir/ritonavir/tenofovir/emtricitabine Group B. The initial six subjects (Group A) for intensive PK analysis for each regimen will be recruited from the the UNC ID Clinic or the Moses Cone Health System Infectious Diseases Clinic, and will be comprised of non-frail subjects not currently receiving interacting drugs. If subjects provide informed consent, timed blood samples will be obtained to determine pharmacokinetic parameters around an observed dose of one of the two study regimens. A whole blood sample will also be collected and stored for potential drug metabolizing enzymes and transporters genotyping in the future. Group A subjects will complete a follow-up visit after their sampling visit. 50 subsequent subjects (Group B) for each regimen will be screened simultaneously, with no more than 10 subjects enrolled for each regimen in Group B prior to the completion and analysis of Group A. These subjects will also be recruited from either site. Group B subjects will have one or two sampling visits with 1 to 4 blood samples obtained at each visit, with a stored sample for future genotyping obtained on one of the visits. Samples will be collected just prior to a dose, at 2 hours, between 4 and 6 hrs, and between 10 and 14 hours after a medication dose. These visits may coincide with the subjects' regularly scheduled visit to the clinic, or be scheduled separately, depending on the preference and availability of the subject.
The purpose of this study is to compare the levels of immune and inflammatory markers among HIV-1, HSV-2 co-infected adults achieving plasma HIV RNA suppression to <50 copies/mL, between those randomized to valacyclovir and placebo, over a twelve-week intervention period.
Human Immunodeficiency Virus (HIV) infection is permanently established by integrating a deoxyribonucleic acid (DNA) copy into the human chromosome, a step also necessary to complete the Human Immunodeficiency Virus (HIV)replication cycle. Standard treatment of HIV infection suppresses Human Immunodeficiency Virus (HIV)replication and has not been able to eliminate Human Immunodeficiency Virus (HIV)from an infected person because of the integrated Human Immunodeficiency Virus (HIV). Raltegravir (RAL), the first approved antiretroviral (ARV) in a new class called integrase inhibitors, works by preventing integration of Human Immunodeficiency Virus (HIV). For participants with Human Immunodeficiency Virus (HIV)who have never taken antiretroviral medications, this research study will test whether Raltegravir (RAL), a recommended first-line ARV, can eliminate Human Immunodeficiency Virus (HIV)from key immune system cells.
Intervention to investigate the efficacy of a nutritional supplement among ARV-naïve, asymptomatic HIV positive patients with a CD4 count in the range 300-550 cells/ul.
This study will draw from proven interventions to refine and pilot test a cue card driven computer-assisted intervention, along with HIV/STI testing, that will be tailored to each participant's demographic characteristics, risk behaviors, and biological test results. The specific aims of the proposed study are: 1. To refine a cue card driven computer-assisted risk reduction intervention that will be tailored to each participant's demographic characteristics (e.g., gender, ethnicity), risk behaviors, and biological test results (HIV, hepatitis B and C, syphilis and herpes). 2. To pilot test the tailored intervention's effects on sexual risk behaviors (e.g., frequency of unprotected sex, condom use), drug use during sex and injection risk behaviors (e.g., direct syringe sharing, indirect sharing practices) using a two-group randomized design that compares the tailored intervention with a delayed treatment control condition. 3. To assess the feasibility and acceptability of the tailored intervention in a rural setting.
This observer-blind study will evaluate the safety and immunogenicity of GlaxoSmithKline (GSK) Biologicals' investigational Herpes Zoster (HZ) vaccine GSK1437173A in Human Immunodeficiency Virus (HIV) infected subjects, firstly enrolling subjects treated with antiretroviral therapy (ART) and with high CD4 T cell counts, and subsequently ART-treated subjects with low CD4 T cell counts, and ART-naïve subjects with high CD4 T cell counts. This Protocol Posting has been updated following Amendment 1 of the Protocol, August 2010. The impacted sections is exclusion criteria.
Objective: This research agreement brings together French and Canadian teams of scientists, HIV testing centers and community based partners. The aim is to explore the feasibility and limitations of offering community based rapid HIV testing to men who have sex with men (MSM).
The incidence of lymphomas is increased among HIV infected patients. In 70 % of cases, those are Non Hodgkin's lymphomas (NHL) and Hodgkin lymphomas (HL) in 30% of cases. In France, their incidence is estimated to 100 cases per year (data from the "Base de données Hospitalière Française sur l'Infection à VIH" (FHDH)). The main mechanisms involved in lymphomagenesis are immune dysfunction, involvement of oncogenic viruses (Epstein-Barr (EBV) and HHV8) and molecular oncogenic events. A better understanding of these different pathways, give the possibility to design specific treatments. The treatment of these lymphomas is not standardized. A prospective study of patients with HIV associated lymphoid malignancies is an innovating tool to answer epidemiological, physiopathological and therapeutic questions. We propose a prospective multicentric study of these patients. The main objectives of this prospective study are to: - evaluate the incidence, characterise clinically and histologically NHL and HL cases associated to HIV - perform an observational study of the treatment and outcome of these patients out of the context of clinical trials, - study the differentiation and activation of B-cell populations, - better understand the role of specific T cell responses in the control of EBV infection, - allow other biological studies from the ANRS group " Lymphome et VIH ". The recruitment of 40 cases per year is expected. The length of inclusions is 7 years. The follow-up will be of 2 years. Clinical, pathological and biological data at diagnosis and during follow-up will be collected. This will allow characterizing the lymphoma, the HIV infection, the antitumoral treatments and the outcome of lymphoma. Biological samples will be centralized to collect cell, DNA, RNA, plasma, serum and tumour collections (Y.Taoufik, S Prevot* ). To better understand the EBV infection and lymphomagenesis in HIV infection, we propose to follow the viral load and the molecular characteristics of EBV in PBMC, plasma and tumour (P.Morand* , V.Boyer* ), to investigate the EBV-T cell responses (G.Carcelain) and the presence and reactivation of EBV in peripheral B cells (C.Amiel* , JC Nicolas) and in tumoral samples (M.Raphael* , I.Joab* ). The other mechanisms of lymphomagenesis in HIV infection will be studied by the analysis of the sub-populations of B-cells in terms of activation and differentiation (Y.Taoufik) and by the characterization of MSI tumours (A.Duval).
