The purpose of this study is to evaluate the safety of and adherence to a vaginal matrix ring (VR) containing dapivirine and oral emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) in adolescent and young adult females.
In the US, fewer than 6% of all youth living with HIV (YLWH) achieve HIV viral suppression. However, health disparities among youth extend across the entire HIV care continuum in that there is a strong association between younger age and later HIV diagnosis, lower engagement in care, lower levels of antiretroviral therapy (ART) adherence, and worse HIV clinical outcomes. In response to this critical public health dilemma, the investigators propose to develop a novel mobile health application ("app") to improve engagement in health care and ART adherence and to pilot test this mobile health app in 18-29-year-old YLWH residing in San Francisco. The aims of this study are to: Aim 1: Build on a theory-guided model and formative work to complete the development of a novel personalized mobile health app for improved HIV clinical outcomes among YLWH (includes field test of initial release to ensure adequate usability and engagement). Aim 2: Conduct a six-month single arm pilot study to examine WYZ feasibility and acceptability among YLWH ( N = 76) living in the San Francisco Bay Area. Finally, the investigators will conduct in-depth qualitative interviews with a subset of participants (N = 20) and clinical team members (N = 10) whose patients participated in the pilot study. The investigators hypothesize that this mobile health app will be feasible and acceptable and will result in improved HIV clinical outcomes. Upon completion, the investigators will be ready to test the efficacy of this app in a subsequent large-scale randomized control trial among a population that is disproportionately impacted by HIV and at elevated risk for poor clinical outcomes.
Through close collaboration with the Ugandan Ministry of Health, the investigators plan to provide PrEP for HIV-negative members of HIV serodiscordant couples by launching PrEP delivery within 12 public ART clinics in Kampala, Uganda. Intervention delivery will be launched in a staggered fashion among clinics through a stepped wedge cluster randomized trial providing a rigorous research opportunity to measure the effect of the intervention on PrEP and ART initiation and adherence. To measure these outcomes using clinic records and biomarkers, the program will enroll approximately 1440 HIV serodiscordant couples. Additionally, the program will collect qualitative and quantitative data to determine if PrEP-taking is a modeled behavior that facilitates ART use and characterize the way that PrEP and ART use interact within couples and estimate the programmatic costs of the integrated PrEP and ART strategy.
HIV prevalence among incarcerated youth living with HIV (YWH) is three times that of the general population and one in seven of all persons with HIV experience incarceration each year. Furthermore, less than half of all youth in the United States with HIV achieve HIV viral load suppression, due to poor retention and adherence to anti-retroviral therapy (ART). Existing linkage and retention services are insufficient to meet the acute needs of youth with HIV who are at risk for incarceration, recently experienced incarceration or arrest, or those nearing reentry from a correctional facility. This holds particularly true in the high-need period following release from incarceration. The LINK2 study will develop and implement a youth service navigation (YSN) intervention to improve linkage and retention among YWH at risk for incarceration and with current incarceration and arrest histories and analyze results to address existing gaps in the literature. The investigators will enroll 142 YWH, aged 16-25 (+364 days), incarcerated in Los Angeles and Chicago jails and through community providers serving those at risk for incarceration and YWH with recent incarceration and arrest histories. The investigators will randomize participants to the YSN intervention (n=71) vs. a usual-care control group (n=71). The youth services navigators (YSNs) will assist with addressing immediate unmet needs such as housing, transportation, and food prior to clinical care and ongoing; will guide intervention participants to a range of community services to support progress along the continuum of HIV care; and will provide direct ART adherence support. The proposed study has two Primary Specific Aims: 1. Adapt an existing peer navigation intervention for adults to create a Youth Service Navigation (YSN) intervention sensitive to sexual and gender minority (SGM) culture that guides youth to needed services along the continuum of HIV care. This intervention combines medical, substance use and mental health care with comprehensive reentry support for YWH, aged 16-25 (+364 days) upon release from large county jails and juvenile detention systems or with arrests in the prior 12 months and those at risk for incarceration based on various social determinants. 2. Using a two-group RCT design, the investigators will test the effectiveness of the new YSN, youth SGM-sensitive intervention among YLWH aged 16-25 (+364 days), compared to controls offered standard of care. The investigators will evaluate the YSN Intervention's effect on post-incarceration linkage, retention, adherence, and viral suppression, as well as on substance use disorders, mental health, services utilization, and met needs. Secondary Aims: The investigators will assess YSN's effects on recidivism, costs and potential cost-offset/effectiveness.
Despite increasing knowledge about and use of PrEP nationally, HIV continues to have disproportionate impact among cisgender men and transgender persons who have sex with men and transgender persons (MSM/TG), with methamphetamine (meth)-users being at particularly high risk. Building on their preliminary work, the investigators will pilot text messaging and peer navigation interventions to support PrEP use among meth-using MSM/TG with potential to be cost-effective, scalable, and easily adaptable.
STRIDE2 is a longitudinal, non-randomized study of individuals living with HIV who are dependent on opioids. This study is funded by the National Institute on Drug Abuse (R01DA030768, Altice, PI; Taxman & Lawson, Co-PIs) and is being conducted by George Mason University, Yale University, and Howard University.
Background: Human immunodeficiency virus (HIV) infection is a serious disease with no cure. Some people with HIV have depression and other mood problems. They can have problems with thinking and memory. Researchers think 2 chemicals in the brain may cause those problems. The chemicals are serotonin and dopamine. The researchers want to take images to learn more about those chemicals in HIV patients. Objective: To learn how HIV affects serotonin and dopamine in the brain. Eligibility: Adults ages 18-70 with HIV who have been on antiretroviral treatment for at least 1 year Healthy adults ages 18-70 All participants must be already enrolled in protocol 13-N-0149. Design: - Participants will be screened with a urine drug test. The results could be shared with insurance companies. - Participants who could be pregnant will have a pregnancy test. - Participants may have a physical exam and blood tests. - Participants will have 1 or 2 positron emission tomography (PET) scans. A needle will guide a thin plastic tube (catheter) into an arm vein. A radioactive drug will be injected into the plastic tube. This is a tracer that helps researchers understand the PET images. - Participants who have the dopamine scan will have to fast for 4-6 hours before the scan. They will take a pill to help direct the tracer to the brain one hour before the scan. - Each scan will last about 1.5 hours. - Participants will be asked to drink a lot of fluids and empty their bladder frequently for the rest of the day after each scan.
The project will evaluate cost and treatment outcomes of a simplified hepatitis C virus (HCV) testing, treatment and care model integrated with HIV testing and treatment among key affected populations including people who inject drugs (PWID) in Myanmar.
The proposed study aims to develop an intervention that is strategic in that it will 1) be a focused on an approach that combines an in-person session with post-session, two-way text messaging to continue the intervention and reinforce the gains from the in-person session and 2) ultimately find HIV+ Black men who have sex with men who have left HIV care where they are likely to present (e.g., city and county health clinics, community-based organizations, emergency rooms).
