Filter by:In a region with 15-20% HIV prevalence, an estimated 20% of HIV-uninfected women could have HIV exposures in pregnancy. In a theoretical scenario of perfect PrEP coverage, all women at risk receive PrEP while no women not at HIV risk receive PrEP (Figure 4). With mandatory PrEP given to all women (similar to the approaches used for malaria prophylaxis), all women at risk would be covered but many women not at risk receive unnecessary PrEP. Our premise is that a targeted PrEP model may be closer to perfect coverage than a universal offer/self-select model. Implementing targeted PrEP through strategies that include facilitation of partner testing with self-tests could add HIV prevention benefit by increasing partner HIV diagnosis and treatment similar to the initiation of PrEP among pregnant women. By implementing these strategies and measuring uptake, use, and HIV incidence, we can inform the best health systems model for PrEP delivery in pregnancy.
The main aim was to conduct a pilot field test of a group-based depression and adherence counseling intervention with HIV-infected women in the perinatal period. Participants were HIV-infected women living in KwaZulu-Natal, South Africa.
This study evaluates strategies aimed at promoting exclusive breast feeding for 6 months followed by continued breastfeeding for the next 6 months with introduction of complementary foods among HIV infected women in a resource limited setting.
This research is a feasibility pilot of an intervention to respond to positive screening tests for mental health(MH) and substance use (SU) captured through the Patient Reported Outcomes questionnaires (PROs). The PROs are currently performed in the clinic, however, the results are neither reviewed with patients nor transmitted to providers. This pilot assesses the feasibility of moving the PROs into the clinical realm by having patients review the PRO results, identifying an issue to discuss at the patient's next HIV primary care visit, and determining whether this process increases discussion of MH and SU disorders in the subsequent clinical visit and/or increases referrals to MH and/or SU treatment.
A phase IV, multicentre, randomised, open-label, pilot clinical trial designed to evaluate HIV-infected, aviremic patients who receive treatment with the combination of DTG/3TC/ABC and who have neuropsychiatric adverse effects that, in the opinion of the investigators, may be related to taking DTG/3TC/ABC, if they improve after switching antiretroviral therapy to the combination of ELV/COBI/FTC/TAF.
Effective management of patients on antiretroviral therapy (ART) is essential to improve clinical outcomes and prevent HIV transmission, but monitoring life-long ART for over 15 million HIV-infected people has become a challenge, particularly in low- and middle-income countries (LMICs). As programs continue to focus on identifying HIV-infected people and starting ART at higher CD4 thresholds, HIV providers have been overburdened, which has resulted in falling retention rates. As ART coverage scales up to include millions more people, additional strain will be placed on HIV clinicians and laboratories to manage stable patients on chronic ART. Implementing point-of-care HIV VL testing to enable task shifting to nurses for chronic HIV care may help mitigate these burdens. Point-of-care Viral Load (VL) testing is intended to differentiate patients who are potentially failing on their ART, so that they can be referred to the next level of care for possible ART regiment change, from patients who are virally suppressed on ART and can be managed by nurses. The investigator's scientific objective is to test the clinical equivalence and reduced cost of implementing a model for chronic HIV care that uses a point-of-care HIV VL assay to enable streamlined care and task shifting among healthcare workers at an urban clinic in South Africa. The central hypothesis is that rapid HIV VL testing, implemented by nurses, is an effective and cost-efficient strategy for management of chronic HIV infection in the majority of patients, thereby allowing more resources to be directed at the minority of patients who need greater attention. This work is innovative because it uses a randomized evaluation of an implementation model that combines a novel diagnostic point-of-care test with streamlined care and task shifting among healthcare workers compared to standard of care for chronic HIV care in a resource-limited setting. This randomized trial will then form the basis of a larger, multicountry proposal to demonstrate the clinical equivalence and cost-effectiveness of implementing an integrated point-of-care HIV VL testing and streamlined care model for chronic HIV care in LMICs. If nurses using clinic-based HIV VL testing are cost-effective for achieving both viral suppression and retention in care among patients on ART, then implementation of this chronic HIV care model would alleviate the strain on existing HIV providers and laboratories in LMICs.
There is great variability in susceptibility from one person to another, and less than one in a hundred sexual exposures to HIV results in infection. In addition, some recent trial of methods to prevent HIV - including vaccines and microbicides - have actually increased HIV acquisition among trial participants for reasons that we do not fully understand. While we know that immune differences in the genital lining are an important determinant of whether a person is infected after a sexual HIV exposure, we don't know enough about these differences to be able to accurately assess a person's individual HIV risk. Therefore, the development of safe and non-invasive laboratory tests to estimate a person's susceptibility in the genital tract would be useful in clinical studies of new HIV prevention tools.
The investigators implemented and evaluated a pilot program in Shinyanga Region, Tanzania to bring prevention of HIV services to communities using community health workers (CHWs). The intervention aimed to integrate community-based maternal and child health services with HIV prevention, treatment, and care—bridging the gap between women and facility, and enhancing the potential benefits of Option B+. Option B+ is the current World Health Organization recommendation for prevention of mother-to-child transmission, but its success in sub-Saharan Africa may be threatened by overburdened clinics and staff. Consequently, paraprofessionals like CHWs can be key partners in the delivery and/or enhancement of health services in the community. The study focuses on whether this approach: increases retention in care; improves adherence to antiretrovirals (ARVs); or improves the number of women initiating antiretroviral therapy and the timing of initiation. Investigators hypothesize improvements along primary and secondary outcome indicators in the treatment group. This evaluation helps illuminate both the impact and feasibility of the intervention, and the role that CHWs may play in the elimination of mother-to-child transmission services.
A 4-armed cluster randomised controlled trial conducted among secondary schoolgirls in Siaya, western Kenya, where clusters are the unit of allocation and schoolgirls the unit of measurement. The overall aim of the trial is to inform evidence-based policy to develop intervention programmes which improve adolescent girls' health, school equity and life-chances. The primary objective is to determine the impact of menstrual cups or cash transfer alone, or in combination, compared against controls, on a composite of deleterious outcomes (HIV, HSV-2 infection, and school dropout) over 3 schoolyears follow-up.
This is a prospective, non-randomized, open-label study to look at the uptake, adherence to, and impact of pre-exposure prophylaxis (PrEP), antiretroviral therapy (ART), semen washing, and vaginal insemination to prevent HIV among HIV-discordant couples attempting conception in Zimbabwe.
