Filter by:Testing and Linkage to Care for Injecting Drug Users in Kenya: Interventions for people who inject drugs (PWID) in sub-Saharan African have been almost entirely absent, despite the fact that in countries like Kenya they contribute a growing proportion of incident HIV infections. This study will leverage a historic decision in Kenya to launch needle exchange program (NSP) and related services for this most-at-risk population (MARP). The investigators will use this NSP/MARP platform to seek out PWID, deliver rapid HIV testing, point of care CD4 count and link to ART using peer case managers, and evaluate community viral load impact using a stepped wedge cluster-randomized design. Lessons learned will have important applicability throughout sub-Saharan African. HCV Among PWID in Kenya: A Supplement to the TLC-IDU study: The prevalence of HCV in Kenya, where an increasing number of people who inject drugs (PWID) live and are becoming HIV- as well as HCV-infected, has not been defined. We will establish HCV prevalence among PWID in Nairobi, Western, and Coastal region by adding HCV rapid and confirmatory tests in our parent PWID study (TLC-IDU Kenya); deliver appropriate counseling and treatment options to those eligible; collect HCV treatment adherence data; and disseminate study findings. These data will provide novel and relevant information about HCV and HIV co-infection in Kenya among PWID that will be immediately applicable in terms of public health impact to national and regional HCV testing, counseling, and clinical management policy.
The aims of STRIDE were changed as of July, 2014. The revised project, called STRIDE2, has a longitudinal, non-randomized, observational study design. The population under study consists of individuals living with HIV who are dependent on opioids.
The RV 156A clinical trial is evaluating an experimental HIV vaccine in people who are not infected with HIV. Participants in that study are randomly assigned to receive either the HIV vaccine or placebo. This study will enroll people who are participating in the RV 156 study. In this study, researchers will evaluate the safety of and immune response to a different experimental HIV vaccine in people who participated in the RV 156 study.
Currently, no vaccine prevents HIV infection. This study will test the safety and immune responses of an HIV-1 DNA vaccine in HIV-uninfected adults in a Ugandan population.
This is a study to determine the safety of dapivirine gel and dapvirine film for healthy, HIV-uninfected women aged 18-45 years using the product for 7 daily doses.
Background: - Some people with human immunodeficiency virus (HIV) develop problems with thinking and concentration when the virus affects the brain. This is known as mild neurocognitive disorder (MND). Research has shown that some HIV medications do not get through the blood brain barrier very well. P-glycoprotein (P-gp) is a brain protein that is part of the blood brain barrier. Differences in the activity of P-gp may help explain why some people with HIV develop MND. It is also possible that MND is partly due to inflammation in the brain. Researchers want to study P-gp and its effect on MND and HIV infection. Objectives: - To study P-gp and brain inflammation related to HIV infection. Eligibility: - Individuals between 18 and 60 years of age who have HIV and either do or do not have MND. - Healthy volunteers between 18 and 60 years of age. Design: - Participants will be screened with a medical history and physical exam. Blood and urine samples will be collected. - Participants will have one outpatient visit and one 3-day inpatient stay. - At the outpatient visit, participants will provide blood samples and have a lumbar puncture (spinal tap). The spinal tap will collect cerebrospinal fluid for study. - At the inpatient visit, participants will have two positron emission tomography (PET) scans of the brain. These scans will study brain activity and possible inflammation. One scan will involve a study drug called tariquidar, which blocks the activity of P-gp. A second lumbar puncture will be done before the first PET scan. Blood and urine samples will be collected daily.
The purpose of this study is to examine the safety, tolerability, and immune response to killed-whole HIV-1 (SAV001-H) vaccine as a primary vaccination regimen in HIV infected individuals.
Dyslipidaemia, characterized by raised triglyceride and low-density lipoprotein (LDL) cholesterol and reduced high-density lipoprotein (HDL) cholesterol levels, is common in HIV-infected individuals, and has been associated with HIV infection itself and antiretroviral therapy (ART). These abnormalities are well-established markers of cardiovascular (CVD) risk in the general population. Studies have suggested an increased risk of CVD associated with ART exposure over and above that conveyed by traditional cardiovascular risk factors. In HIV population to reduce lipid parameters, the most usual clinical strategy remains to add a statin treatment. Recent studies suggested ART switch can represent an interesting alternative to statins to reduce lipid plasma levels. The purpose of this study is to evaluate the frequency with which the replacement of LPV/r (lopinavir/ritonavir), ATZ/r (atazanavir/ritonavir), DRV/r (darunavir/ritonavir) or EFV (efavirenz) by ETR (Etravirin) in dyslipidemic patients with suppressed viremia would obviate the necessity to administer statins. A prospective, phase III study in which the statin treatment of dyslipidemic HIV patients on antiretroviral drugs (ARVs) will be interrupted during 4 weeks is proposed. At week 4, patients qualifying for a lipid lowering drug (calculated LDL-C≥ 3mmol/L) will replace EFV, LPV/r, DRV/r or ATZ/r by ETR. The proportion of patients not qualifying anymore for a statin treatment at 12 weeks (i.e. after 8 weeks of ETR treatment) will be determined. Additionally, the lipid level changes will be assessed at 12 weeks. Inflammatory markers will be measured at baseline, at drug switch and at the end of the study Study drug will be provided by the drug manufacturer (Janssen-Cilag, AG). Compliance for study drug will be done at week-4 and week-12, Returned study medication will be counted and the amount notified on the Case Report Form (CRF).
In this study, it is hypothesized that helminth infections modulate immune responses against HIV-1 infection resulting into increased HIV-1 multiplication, faster progression to AIDS and increased episodes of AIDS-related opportunistic infections. Furthermore, the effect of helminth infections on progression of HIV-1 infection is dependent on helminth infection intensity, host background immunity, nutritional status, demographic factors and socio-economic status. Also, treatment of helminth infections using praziquantel and albendazole among HIV-1 infected individuals will lead to reduction in HIV-1 viral loads, improvement of CD4+ counts, CD4+/CD8+ ratio and Hb levels, improved weight gain and reduction of episodes of HIV-1 related opportunistic infections. In addition, HIV-1 infection is associated with poor anthelminthic treatment outcome as compared to non-HIV infected individuals
The purpose of this study is to study the kinetics (study of the rate of change) of immune recovery quality and function in stored plasma blood samples of treatment-naive (not previously treated with antiretroviral drugs) patients with advanced human immunodeficiency virus (HIV) infection starting a Darunavir/Ritonavir- or Efavirenz-based highly active antiretroviral therapy (HAART) regimen.
