Filter by:Antiretroviral treatment for HIV has allowed patients to have undetectable viral load indefinitely. Despite that, HIV infection has become a chronic inflammatory disease, with increased mortality. This pro-inflammatory state is in part explained by the dysbiosis of intestinal bacterial populations. However, little is known on the impact of the antiretroviral treatment on this population and very few studies have evaluated these alterations. The aim of this study is to study microbiome on healthy patients and HIV-infected patients exposed to antiretroviral treatment with integrase strand transfer inhibitors.
Traditional healers, community-based partners with the national health system of South Africa, are exposed to patient blood an average of 1,500 times during their careers due to the practice of delivering herbal remedies via herbs rubbed into dozens of sub-cutaneous cuts. The purpose of this proposal is to compare two implementation strategies to increase consistent use of Personal Protective Equipment (PPE): (1) a health care worker provided training program followed by 3 educational outreach and coaching visits at the healer's place of practice vs. (2) a training and educational outreach initiative led by a team of health care workers and healers who adopted and use PPE on their own (early adopters) to assess their effects on exposure to patient blood. With an HIV prevalence among healers well above that in the baseline population (30% vs. 19%) and HIV prevalence of 59% among those exposed to patient blood, this study will allow the investigators to test a novel implementation strategy for delivering PPE training to prevent new HIV infections among a newly identified high-risk population in a region with the world's highest HIV prevalence.
The prevalence of HIV-associated wasting declined dramatically with the introduction of effective antiretroviral therapy (ART), but as patients survive longer on treatment the proportion of overweight (body mass index [BMI] >25 kg/m2) and obese (BMI >30 kg/m2) HIV-infected individuals has been rising over time and is reaching parity with the general population. Adipose tissue has broad effects on immune function relevant to HIV infection, including the basal inflammatory state and peripheral lymphocyte populations, but there are few data on the effects of high adiposity on HIV immunology. This issue is directly relevant to promoting the long-term health of ART-treated individuals, many of which can now survive for decades on treatment, as emerging evidence suggests that increased immune activation is a major risk factor for the development of cardiovascular and metabolic diseases in this population. HIV-infected individuals on ART have an approximately 2-fold higher risk of myocardial infarction and a 4-fold higher risk of type 2 diabetes mellitus, and the proportion of deaths among HIV-infected individuals due to non-AIDS conditions now exceeds those due to AIDS. Despite the increasing proportion of overweight and obese HIV-infected persons, few prior studies have investigated the interaction between adipose tissue, immune activation, and risk factors for cardiovascular and metabolic disease in treated HIV. The overall goal of this study is to understand the complex relationships between adipose tissue, innate and cellular immune activation, and metabolic and cardiovascular disease risk factors in persons on long-term antiretroviral therapy. To this end, we will use an observational, cross-sectional cohort design to compare in vivo markers of immune activation, ex vivo cytokine expression, and metabolic and cardiovascular disease markers in HIV-infected individuals with a range of body composition profiles and between overweight/obese HIV-infected and uninfected individuals.
Background: This is a pilot randomized clinical trial (RCT) to demonstrate the feasibility and acceptability of a structural and behavioral intervention to reduce mortality following hospital discharge for people with HIV (PWH) in South Africa. Investigators' prior study showed that among 121 PWH discharged, 54% were readmitted and 26% had died by six months following discharge. In the prior study, investigators identified that missing clinic visits after discharge was associated with death. Here investigators are seeking to overcome key barriers in piloting a home-based post-hospital care intervention. Investigators' approach is informed by a conceptual model of key barriers to the care transition along with a behavioral explanatory model, the Behavioral Model for Vulnerable Populations. The overarching goal of this study is to tailor and pilot the intervention that shifts initial post-discharge care from the out-patient clinic to the home and provides patient-centered counseling (Home Link intervention). For the intervention to prove effective it will need to substantially reduce post-discharge mortality. Specifically, in the Home Link intervention, a team will conduct home visits to (1) provide a structured clinical assessment; (2) reconcile medications, (3) provide psychosocial support through patient-centered counseling, and (4) assess home needs (food security). These visits will start one week after discharge and be repeated every two weeks until the participant is stabilized and ready to initiate lower intensity clinic-based services or three months have elapsed. Aims: The aims of the study are to pilot a randomized clinical trial of home delivery of health services during the post-hospital period for PWH. Methods: This project is a pilot randomized clinical trial (RCT) to refine and test the feasibility, acceptability, and preliminary effectiveness of the HomeLink intervention. At the conclusion of the R34 grant period investigators will have a protocol and procedural manual ready for a full RCT powered for effectiveness. Significance: The proposed study is consistent with NIH HIV/AIDS highest priority research and the South African National Strategic Plan on HIV, tuberculosis (TB), and sexually transmitted infections (STIs) 2017-2022. The research addresses the HIV/AIDS Research Priority of "retention and engagement in these services, and achievement and maintenance of optimal prevention and treatment responses."
This study will compare the pharmacokinetics of the component drugs in JULUCA, and HIV combination treatment pill, in HIV-negative patients who require hemodialysis with those with normal renal function.
This study aims to test if small incentives promote linkage to care and 6-month viral suppression among individuals recently tested for HIV at selected sites within Johannesburg, South Africa. Individuals who obtain a reactive HIV test result will be randomized to receive either the standard of care (SOC) for linkage to care or to receive financial incentives for confirmatory testing, linkage to care and viral suppression.
"SKILLZ," is a mixed methods evaluation of the Grassroots Soccer (GRS) SKILLZ Package based in Lusaka, Zambia. The package is made up of three football-based programs: (1) SKILLZ-Girl - implemented in schools as part of a 10-week program culminating in a tournament event; (2) SKILLZ-Club - implemented as an ongoing extra-curricular activity after the completion of SKILLZ-Girl; (3) SKILLZ-Plus - a clinic based football group targeted at girls that are HIV-positive. The programs work together to build a continued support system which encourages uptake of Sexual Reproductive Health (SRH) and HIV services, while facilitating ART adherence (for HV-positive participants) and continued engagement with health services over the long-term (whether to contraceptive methods, HIV prevention services, HIV repeat testing, and/or HIV treatment and care). The study team has developed an enhanced SKILLZ-Girl offering, which will include a comprehensive module on HIVST, contraceptives and PrEP, access to a nurse during the implementation of sessions and the additional offering of HIVST and contraceptive services at the event along with ongoing engagement through the SKILLZ-Club program (Enhanced Arm) , The central hypothesis is that this enhanced curriculum will increase HIV testing and contraceptive uptake compared to the standard SKILLZ curriculum & standard event (SOC Arm). The investigators further hypothesize that the intervention in the enhanced arm will positively and directly affect a number of mediating factors including attendance at soccer events where community-based SRH services are offered, SRH knowledge, empowerment, self-confidence, and perceptions of gender balance, and (reduced) stigma. For girls found to be HIV-positive, the follow-on SKILLZ intervention (SKILLZ-Plus) has been designed to facilitate linkage to HIV care and treatment, reduce HIV-related stigma, increase disclosure to family and partners, increase feelings of social support, empowerment, self-efficacy, and ultimately adherence to ARVs, viral load suppression (VLS) and retention in HIV care and treatment. This study will be conducted in up to 32 secondary schools that GRS currently serves in the Lusaka Urban District.
This is an open-label, single sequence study that is being conducted to investigate the potential drug-drug interaction (DDI) when GSK3640254 is co-administered with a cocktail of cytochrome P450 (CYP) enzymes and transporter probe substrates in healthy participants. This study will aid in understanding these interactions and resulting changes in exposure (if any) when drugs that are metabolized via these pathways are given in combination with GSK3640254. The study will consist of a Screening period and 3 sequential treatment regimens. Participants will be administered a single dose of probe substrate drugs (caffeine 200 milligram (mg), metoprolol 100 mg, montelukast 10 mg, flurbiprofen 100 mg, omeprazole 40 mg, midazolam 5 mg, digoxin 0.25 mg and pravastatin 40 mg) on Day 1. Participants will then receive GSK3640254 200 mg once daily on Days 11 to 20 followed by co-administration of probe substrate drugs with GSK3640254 on Day 21.
The aim of this study is to examine the effect of mHealth tools on antiretroviral (ART) adherence and persistence among HIV-infected individuals with co-occurring cocaine use disorders (CUDs).
This study aims to: 1) adapt the theory-based P3 (Prepared, Protected, emPowered) app designed to improve pre-exposure prophylaxis (PrEP) adherence, retention in PrEP clinical care, and PrEP persistence among young men who have sex with men (YMSM) in the United States for YMSM in Thailand, and 2) conduct a pilot randomized controlled trial (RCT) to assess the feasibility, acceptability, and potential impact of the adapted P3-Thailand (P3-T) app.
