Filter by:Following the announcement of the global "90-90-90" strategy, there is a huge need in South Africa for effective well-developed scaled-up models of ART (anti-retroviral therapy) delivery that aim to improve patient adherence and viral suppression. The ART adherence club is one such model of service delivery. The investigators are conducting a pragmatic randomised control trial to compare virological outcomes 12 months post-ART initiation between arms: individuals referred to the Adherence club at 4 months post-ART initiation (early referral) and individuals referred to the Adherence club at 12 months post-ART initiation (delayed referral). Individuals with delayed Adherence club referral will continue to attend the ART clinic as per the Standard-of-Care.
Two new rapid HIV tests by Alere™ have the potential to substantially decrease the window period for rapid tests. First, the Alere™ HIV Combo is a rapid fourth generation test. The performance in a laboratory based setting was recently assessed at the Thai Red Cross Anonymous Clinic Laboratory in Bangkok, Thailand (personal communication). Of 50 confirmed acute HIV samples, Alere™ HIV Combo could detect 37 (74%), while none of these 50 cases could be identified by the currently used third generation tests. These data have not yet been published, but the preliminary results indicate a very favorable performance of the Alere™ HIV Combo in a facility-based laboratory setting. Second, the Alere™ q HIV-1/2 Detect is a qualitative, cartridge based, nucleic acid amplification test designed for Point of Care use. Data from several early infant diagnosis studies in Sub-Saharan African countries have assessed the performance of the Alere™ q HIV-1/2 Detect. The test was performed in the field, by a range of health professionals, from nurses and laboratory technicians to medical doctors. The pooled analysis showed a sensitivity of 99.07% (95%CI 95.48 - 99.95%) and a specificity of 99.94% (99.72-100%).
Young gay, bisexual, and other men who have sex with men (YMSM) are the only risk group in which rates of new HIV infections are on the rise. There has been a relative dearth of research dedicated to understanding these health disparities between gay/bisexual and heterosexual youth, and even less has focused on identifying factors that might promote resilience against negative health outcomes. Understanding both risk factors and processes of resilience is critical in developing efficacious interventions to improve health in this population. Through a grant from the National Institutes of Health, the investigators completed formative research with young male couples. Qualitative interviews identified preferences for couples-based intervention format and content. While coupled YMSM expressed some interest in HIV prevention, participants were most interested in building relationship skills. Coupled YMSM preferred group-based interventions in order to meet and learn from other couples but had concerns about discussing personal topics in groups. Quantitative analyses found that the rate of condomless sex in couples increased from adolescence to young adulthood. Further, the influence of older partners, partner violence, and drinking before sex were strongest in emerging adulthood. Informed by these, the research team developed 2GETHER, which aims to reduce HIV transmission risk in couples by enhancing relationship functioning. 2GETHER is a four session program. The first two sessions are group sessions aimed at skills building, and the second two sessions are individualized couple sessions aimed at skills implementation. Modules address communication skills, coping with stress (both general and sexual minority-specific stress), relationship sexual satisfaction, and HIV transmission risk within the dyad and with outside partners. 2GETHER was designed to address HIV transmission risk in couples regardless of HIV status; couples learn to use behavioral and biomedical approaches to prevent both HIV acquisition (e.g., HIV testing, condom use, pre-exposure prophylaxis) and transmission (e.g., medication adherence to reduce viral load), with an overarching emphasis on the health of the couple. The investigators completed a pilot trial of 2GETHER with funding from Northwestern University. The pilot trial enrolled 57 couples (N=114) and demonstrated feasibility, acceptability, and preliminary efficacy of 2GETHER. This pilot trial used a non-randomized pre-/post-test design because the goal was to evaluate feasibility, acceptability and preliminary effects in a large number of diverse couples to inform a future efficacy RCT. Post-test occurred 2 weeks post-intervention, or ~2 months post-baseline. The pilot trial recruited a diverse sample of couples in less than one year and each program module receive high ratings of acceptability during post-sessions evaluation and an exit interview. At the 2-week post-test, the investigators observed significant decreases in HIV risk behavior, improvements in motivation to reduce HIV risk, and improvements in relationship investment. The current study will conduct a randomized controlled trial (RCT) to test the efficacy of 2GETHER, a novel couples-based intervention for young men who have sex with men (YMSM) that aims to reduce HIV transmission risk by optimizing relationship functioning. The investigators will conduct an RCT with 200 dyads (total individual N=400), who will be randomized to receive the 2GETHER intervention or an attention-matched couples-based positive affect promotion program.
The purpose of this study is to look at the levels of three HIV medications: Descovy®, Viread® and Rifadin® in the blood after drug intake has been stopped, in order to understand how long these drugs persist in the blood. The study will specifically look at blood levels of these three drugs after taking them every day for 28 days. Participants will take Descovy® on a first stage, a combination of Descovy® and Rifadin® on a second stage, and Viread® on a third stage. If the participants decide to take part, the duration of the study will be up to 85 days plus a screening visit which will take place up to 28 days prior to the start of the study, and a follow up visit, which takes place 28 to 36 days after the last dose of study medication. This study is not randomised which means that all participants will receive all study medications in the same order. The participant and the study doctor will know which study medications the participant is taking at all times during the study. During the study, numerous blood samples will be taken which could cause inconvenience and distress for patients. Every effort will be made by study staff to minimise this. There are a lot of clinic visits during the study and three full days in the unit which may inconvenience patients. However, participants will be made aware of this both verbally and in the patient information sheet. Participants will also receive compensation for their time and travel expenses whilst participating in the trial. Participants or participants' partners who plan to become pregnant during the study will not be allowed to take part in the study. Further to this (if applicable), participants must use effective contraception for the duration of the study. Participants will have to adhere to other restrictions as detailed in the participant information sheet. These restrictions will be explained in full to all participants.
This research study will recruit 200 transgender youths between the ages of 15-24. There are two arms to the research study: the control and the intervention arm. Each eligible participant will be randomized into either arm. The control arm participants receive an OraQuick HIV testing kit sent to an address of their choice and instructions of how to conduct the test. They will enter their results on the research study website and complete surveys at 3 month intervals until an entire year has passed. Participants in the intervention arm will receive an OraQuick HIV testing kit sent to them and will receive video-based counseling called Motivational Interviewing and Certified Testing and Referral. After this counseling session, the results from the OraQuick HIV test will be logged by study staff. Then, participants in the intervention arm will fill out surveys at 3 month intervals until a year has passed.
The purpose of the Tailored Motivational Interviewing Project (TMI) is to develop an implementation intervention to increase evidence-based patient-provider communication strategies using a Motivational Interviewing (MI) framework.
This study is testing the acceptability and feasibility of MyChoices, a mobile application (app), to promote HIV testing and pre-exposure prophylaxis (PrEP) uptake among young men who have sex with men (YMSM).
This study is testing the acceptability and feasibility of a highly interactive mobile application (app) to promote HIV/sexually transmitted infection (STI) testing and uptake of pre-exposure prophylaxis (PrEP) among young men who have sex with men (YMSM).
After enrollment, participants will be randomized to either receive the intervention (treatment) from trained health educators or undergo observation as usual (control group). Randomization will be stratified by HIV serostatus. A control group is appropriate because participants will still receive services offered through probation and will be offered the intervention after completion of the trial. Subjects will be paid, not for participating in the intervention, but for providing research assessments. The newly adapted intervention will be delivered over no more than a 3-month period (it will be shorter if the adaptation process is supportive). Baseline assessments will assess the pre-intervention period. The 3-month assessment will be the end-of-intervention effects and the post-intervention assessments will be at 6, 9 and 12 months. HIV prevention knowledge will be assessed based on quizzes used previously for HHRP+; though final quiz content will depend on final selected materials for the intervention. Subjects will be followed for 12 months with assessments by trained research assistants.
The primary objective of this study is to evaluate the safety of solid organ transplantation using HIV-positive deceased donors (liver, kidney) and HIV-positive living donors (liver) in HIV-positive recipients. HIV-positive individuals who agree to accept and receive a solid organ transplant from and HIV-positive donor will be followed to determine the safety and efficacy of this practice.
