Filter by:HIV-infected people have an increased risk of developing active tuberculosis (TB). To reduce the burden of TB among people living with HIV (PLHIV), the World Health Organization (WHO) recommends systematic TB screening followed by 1) confirmatory TB testing for all those who screen positive and 2) TB preventive therapy (TPT) for all TPT-eligible PLHIV who screen negative. The objective of the TB Screening Improves Preventive Therapy Uptake (TB SCRIPT) trial is to determine whether TB screening based on C-reactive protein (CRP) levels, measured using a rapid and low-cost point-of-care (POC) assay, improves TPT uptake and clinical outcomes of PLHIV, relative to symptom-based TB screening.
The purpose of this study is to characterize the role of human mobility in fueling TB epidemics and estimate the potential impact of innovative case finding interventions tailored to mobile populations
COMEBACK is an investigator-initiated, 48-week study. The study will be conducted in 100 persons living with HIV (PLWH) who have been off ART for two or more weeks. All enrolled participants will be prescribed Biktarvy, if determined appropriate upon review of past historical resistance tests, for use throughout the study period. Participants will also complete a series of Patient Reported Outcomes (PROs) at screening and be assigned one of three tiers of case management intervention (Piggyback, Got Your Back, Backbone), with each tier increasing in intensity regarding intervention techniques and options provided. Participants will be assessed for virologic suppression, retention in care, and PROS throughout study follow up and at study end.
In its 2017 revision of the global guidelines for HIV care and treatment, the World Health Organization (WHO) called for rapid or same-day initiation of antiretroviral treatment (ART) for eligible patients testing positive for HIV. However, to date neither the WHO nor the Zambia Ministry of Health has provided detailed guidance on how to implement this recommendation. In sub-Saharan Africa, where most HIV patients are located, studies continue to document high losses of treatment-eligible patients from care before they receive their first dose of antiretroviral medications (ARVs). Among facility-level reasons for these losses are treatment initiation protocols that require multiple clinic visits and long waiting times before a patient who tests positive for HIV is dispensed an initial supply of medications. There is very little published evidence on the practical details of the process and the extent to which it varies by facility, setting, or country. Without a robust baseline evidence base, it is challenging to identify opportunities for making improvements. The SPRINT (Survey of Procedures and Resources for Initiating Treatment of HIV in Africa) study will begin to develop this evidence base. SPRINT will combine a facility-level description of the standard of care with a retrospective record review of patients who recently initiated ART at the study sites. Data will be collected from 12 health facilities in Zambia. The survey will elicit detailed information about current procedures through structured interviews with clinic staff at the selected health facilities. The record review for a retrospective cohort of patients eligible for ART will estimate actual numbers of clinic visits, services provided, and duration of the steps for treatment initiation from start to finish. SPRINT is expected to identify differences in approaches to treatment initiation and potential opportunities for improvement.

With the introduction of effective anti-retroviral therapy (ART), HIV-infected persons can now survive for decades, but this success has been accompanied by an increased risk of developing metabolic disease and diabetes in HIV-infected persons compared to the general population. Recent studies from HIV-negative subjects have identified several associations between circulating immune cell populations and impaired glucose tolerance, including increased activated CD4+ and CD8+ T cells, and reduced regulatory T cells. Of note, these same changes in peripheral T cell subsets are frequently observed in patients with chronic HIV infection. The goal of this study is to assess whether the circulating T cell distribution is reflective of the adipose tissue T cell distribution, and to understand whether chronic adipose tissue T cell activation may impair adipocyte (i.e., fat cell) function and insulin sensitivity. If the investigators' hypotheses are correct, this will demonstrate that chronic peripheral immune activation (i.e., high memory T cells, low naïve cells, and increased expression of activation surface markers) is associated with greater adipose-resident CD4+ and CD8+ T cell expression of activation markers, adipose tissue inflammation, and insulin resistance.
This project, funded by the National Institute of Mental Health, will test the efficacy of an electronic game to prevent HIV among African adolescents (aged 12-17), delivered via inexpensive Android smartphones. This study involves a sample of 912 young people and 500 of their parents in Kenya's former Nyanza province, where 11.4% of young women and 3% of men ages 15-24 are HIV-infected. This study will be carried out by Emory University and the Kenya Medical Research Institute (KEMRI).
Transgender women (TGW) are at high risk for HIV infection, and are an important, under-researched population in sub-Saharan Africa. Globally, HIV acquisition risk among TGW is 13 times higher than other adults aged 15-49 years. In Uganda, HIV prevalence among TGW is 22% compared to 5.9% in the general population. Encouraging use of self-controlled HIV prevention tools - specifically, HIV self-testing (HIVST), STI self-sampling (STISS) and antiretroviral pre-exposure prophylaxis (PrEP) - to those testing HIV negative could decrease HIV incidence among African TGW. This R34 application proposes formative research and a pilot trial to develop an HIV prevention intervention for African transgender women (TGW). The investigators will evaluate whether peer-delivered combination HIV prevention increases testing uptake and empowers effective prevention decision making in TGW. Peer-led interventions are effective in increasing HIV and STI testing among other hard-to-reach vulnerable populations with high HIV prevalence but low testing coverage and are recommended by the World Health Organization. Exploring peer-delivery approaches to increase coverage of combination HIV prevention interventions is key to addressing research gaps in HIV epidemic control. However, little is known about the effectiveness of peer-delivered combination HIV prevention (HIVST, STISS and PrEP) for African TGW, or the best way to deliver care to this population. Key knowledge gaps include: 1) whether peer delivery increases testing rates and status knowledge, 2) the role of peers in creating demand for repeat testing and PrEP, and 3) how to optimize peer delivery of combination HIV prevention (HIVST, STISS and PrEP). To address these questions, this proposal seeks to conduct formative research to inform implementation of peer-delivered combination HIV prevention for African TGW (Aim 1), implement a pilot cluster randomized trial to evaluate the feasibility, acceptability and preliminary effectiveness of peer delivered combination HIV prevention (Aim 2), and conduct in-depth interviews to explore how peer-delivery of HIVST, STISS and PrEP influences prevention choices among TGW and sexual partners (Aim 3). This will be the first clinical trial, to our knowledge, to evaluate HIV self-testing and STI self-sampling in HIV-uninfected TGW. Pilot data from TGW and their partners will provide unique perspectives to inform HIV prevention delivery. The proposed proof-of-concept evaluation is uniquely positioned to improve prevention uptake for African TGW - a high-risk, marginalized, and underserved population. Rigorous application of mixed methodologies will generate actionable data for policy and programs, and provide a strong foundation for scalable implementation of cutting edge combination HIV prevention interventions for African TGW. The local transgender community is involved in study design, planning and implementation. This project is supported by the Ugandan Ministry of Health.
AFFIRM is an 8-session manualized group coping skills intervention focused on reducing sexual risk behaviours and psychosocial distress among SGMY. AFFIRM is delivered by two facilitators (primarily social workers and peers) through a combination of education and rehearsal (i.e., simulation of real-life experiences) in a manner that affirms participants' sexual and gender minority identities and experiences. AFFIRM is being tested in a five-year trial using a stepped wedge waitlist crossover design, where all participants receive the intervention in clusters.
ADHOC is an observational study of people living with HIV over the age of 50. Data from this study will be used to research the interaction between HIV and aging.
