Filter by:This study aims at assessing the feasibility of implementing an interventional cohort of people who inject drugs in Haiphong, Viet Nam. For this purpose, the investigators will conduct a RDS survey to i) assess the current situation of drug use behaviour, HIV and Hepatitis C Virus (HCV) infection in the study population and ii) recruit participants for the longitudinal phase. The latter will consist of enroling the most difficult to reach People Who Inject Drugs (PWID) (those not followed by health centers), including early injectors, Men who have Sex with Men (MSM) and female sex workers (FSW) and following them up for 6 months in order to estimate the follow-up rate and preliminary estimates of HIV and HCV incidence.
African American men infected with HIV are living longer and are acquiring the same chronic non-communicable diseases affecting the general population of African American men age 40 years and older. African American men have disproportionately high rates of cardiovascular disease, hypertension, diabetes, kidney disease, and cancer, particularly prostate and colon cancer, but HIV is associated with an increased risk for co-morbidity from these conditions, a risk heightened by not only HIV infection itself, but also its treatment with antiretroviral therapy (ART). The risk for many of these chronic diseases is tied to behavior: risk is increased by physical inactivity and unhealthful diet. Although the high risk for behavior-linked chronic diseases among HIV-positive individuals has been recognized, there is a lack of evidence-based interventions specifically tailored to their needs. Hence, the broad objective of this research is to identify strategies to empower HIV positive African American men to engage in behaviors that reduce their risk of chronic diseases. This research will test the efficacy of a theory-based, contextually appropriate health promotion intervention in inducing positive changes in behaviors linked to risk of chronic diseases among HIV positive African American men age 40 years or older and will identify the theoretical variables that mediate its efficacy. In a randomized controlled trial, African American HIV positive men age 40 or older who are receiving ART for HIV will be randomized to the Men Together Making a Difference Health Promotion Intervention, which consists of three, 3-hour weekly intervention sessions, or the 1 session Health Awareness Control Group. The Men Together Making a Difference Health Promotion Intervention is based on social cognitive theory and the reasoned action approach integrated with formative research. Data will be collected at baseline, immediately post, and 3, 6 and 12 months post intervention. The trial will test whether the Men Making a Difference Health Promotion Intervention increases self-reported physical activity compared with the Health Awareness Control Group.
The purpose of this study is to develop markers for use of placebo vaginal products and measure markers of mucosal semen exposure among healthy women. The study will also monitor safety of placebo product use.
Dolutegravir is an HIV-1 integrase inhibitor which is marketed as a single tablet (Tivicay®) and in a fixed dose combination tablet with abacavir and lamivudine (Triumeq®, referred to as TRI). For patients with swallowing difficulties, administration of whole tablets can be problematic and tablets are cut or crushed to ease administration. Currently there is no information about crushing TRI tablets. Therefore this study will be conducted to investigate whether crushed and suspended TRI and crushed and suspended TRI with drip feed are bioequivalent to taking TRI as a whole.
This study aims to provide the evidence that 150mg of cobicistat will have the same effect on the pharmacokinetics of daclatasvir 30mg QD as 100mg of ritonavir, when given together with atazanavir 300mg.
This study is being done to learn about the interaction of alcohol consumption and HIV on brain function. The proposed study will have two broad objectives. The first is to incorporate functional neuroimaging (FMRI) approaches, along with additional Magnetic Resonance Spectroscopy (MRS) methods that will enable a delineation in both functional and cerebral metabolic disturbances affecting specific functional brain systems that are associated with the interaction of ethanol (ETOH) consumption on Human Immunodeficiency Virus (HIV)-associated brain dysfunction. Recent data indicate that HIV infected patients with heavy ETOH consumption have FMRI abnormalities and exhibit alterations on other neuroimaging measures compared to moderate drinkers and people who do not drink at all. The second objective is to examine the extent to which reductions in ETOH consumption among heavy drinkers with HIV infection result from a motivational intervention. The findings from this study will provide important information on how heavy ETOH and HIV interact to affect the brain functional responsiveness, and the extent of improvement that might be gained by reducing heavy ETOH use.
Research Goal: To reconstitute the anti-HIV specific immunity system of the AIDS patients, so the viruses could not massively replicate when HAART was discontinued, then make HIV functional cure possible.
The proposed study will add to the growing understanding of platelet activity and platelet inhibition in subjects with HIV. It will examine the relationship between platelet activity and its inhibition by antiplatelet therapy (aspirin monotherapy and clopidogrel monotherapy) in this high-risk cohort. Furthermore, it will provide important data on the mechanism of platelet activity and its inhibition using biomarkers of platelet activity, inflammation, immune activity and endothelial function and genetic expression profiling.
Kasensero, a fishing community on Lake Victoria in Uganda, is a representative HIV "hotspot" with extremely high HIV prevalence (44.3%) and incidence (~3.9/100py), yet low HIV service utilization. Hotspots such as Kasensero may seed and sustain HIV in general populations, compromising national and regional HIV control efforts. PEPFAR, UNAIDS, and WHO have recognized the urgent need to target hotspots with enhanced HIV treatment and prevention efforts. However, evidence on low-cost, comprehensive, and effective HIV control strategies for hotspots is limited and is thus a priority need for the field. The investigators propose an implementation science, cluster-randomized, controlled trial in Kasensero to evaluate the impact on HIV service uptake and HIV incidence of CHWs promoting combination HIV prevention (CHP) services supported by mobile health technologies (mHealth). CHP is the implementation of multiple, evidence-based HIV prevention services (HIV testing and counseling, antiretroviral therapy, medical male circumcision, and behavior change) to maximize population-level impact on HIV incidence. For CHP to substantively decrease HIV incidence, most community members must be assessed for risk factors and current CHP utilization, then triaged, motivated, linked, and, if HIV-infected, retained in care. The proposed intervention will use low-cost CHWs leveraging mHealth decision support and counseling tools to promote CHP along this entire continuum of HIV service utilization. The hypotheses for this implementation science research are that residents in clusters receiving the implementation intervention will have improved CHP service uptake and decreased Population Prevalence of Viremia (PPDV) compared to controls receiving standard of care. The intervention will be evaluated through a pragmatic, cluster-randomized trial nested within a large, ongoing population-based cohort study of HIV, the Rakai Community Cohort Study (RCCS). Intervention arm participants will be visited in their place of residence by CHWs trained to evaluate and triage participants into risk categories, provide tailored CHP health counseling, linkage, and adherence support, all supported by a mHealth decision support tool. The primary outcomes will be CHP service coverage and PPDV. Other outcomes will be HIV incidence, population viral load, implementation measures, retention, virologic suppression, and sexual behaviors. Complimentary mixed methods (quantitative, qualitative, and cost) evaluations of the trial will be conducted to evaluate implementation processes, facilitators, and barriers to inform study results and future program uptake. Focus groups and in-depth interviews will be conducted during and after the follow-up period and synthesized with quantitative data. Intervention costs will be prospectively measured to provide information on program affordability. Through this study, a novel, low-cost, and scalable implementation intervention to improve CHP uptake will be evaluated in an HIV "hotspot" critical to controlling the HIV epidemic. The study design ensures rigorous evidence of immediate relevance to many stakeholders.
This study aims to recruit a cohort of HIV patients with and without HIV-SN and to identify genetic risk factors for the development of HIV-SN and neuropathic pain. It also aims to more deeply phenotype the condition, using well validated questionnaires, and to identify any influence that early neurocognitive dysfunction may have on the reporting, diagnosis and treatment of neuropathic pain in the HIV population.
