Filter by:This study seeks to determine the clinical efficacy and cost effectiveness of implementing an integrated model for HIV monitoring using point of care (POC) tenofovir (TFV) adherence testing and POC viral load (VL) monitoring in improving ART adherence, maintaining durable VL suppression, and improving retention in care among HIV-positive individuals initiating first-line tenofovir disoproxil fumarate (TDF)-based ART in South Africa.
The need for and timing of booster doses of meningococcal vaccines in People Living with HIV (PLWHIV) is currently unknown. As such it is impossible for clinicians to recommend booster doses or to know if and when these might be necessary.We propose to follow up a group of participants from the Propositive study who received two doses of both MenB (Bexsero) and MenACWY (Menveo). This was a group of PLWHIV between the ages 18-45 years. We propose following up these participants at 18 and 30 months post completion of two doses of vaccine and investigating their immunological response.
This is a multi-center prospective cross-sectional study to determine the burden of decline in intrinsic capacity and functional ability, and the prevalence of geriatric syndromes, such as frailty, and disability in adult people living with HIV (PLWH) in Asia.
The overall aim of this program of research is to test a newly developed intervention, Acceptance-Based Behavior Therapy (ABBT), to improve HIV patients' commitment to medical care. The purpose of the proposed project is to establish the efficacy of ABBT and examine its mechanisms of action. To achieve the specific aims, the investigators will conduct a randomized clinical trial (n = 270), with two treatment arms: ABBT vs. an attention-matched HIV education control condition.
The advent of anti-retroviral therapy (ART) for people living with HIV/AIDS (PLWHA) substantially improved life expectancy but has also led to the critical need to address modifiable risk factors associated with cancer and cardiovascular disease, such as tobacco smoking. HIV-infected smokers lose more life-years due to tobacco use than they do to their HIV infection. There have been relatively few studies of tobacco use treatments for PLWHA and systematic reviews show that there are insufficient data to conclude that tobacco dependence interventions that are efficacious in the general population are efficacious for PLWHA. Further, many studies in this area have lacked randomization and a control group, infrequently used an intent-to-treat (ITT) approach and biological verification of tobacco abstinence, and lacked post-treatment follow-up.10 What investigators do know thus far is that behavioral interventions and the nicotine patch yield moderate effects on cessation; and 2 recent placebo-controlled trials - one in France and one by this lab - found that varenicline is safe and effective for treating tobacco use among PLWHA, but yield quit rates that are substantially lower than those reported in the general population. Thus, there is a critical need to rigorously test novel ways to optimize tobacco cessation treatment for smokers with HIV.
The purpose of this study is to test the efficacy of a theory-driven peer intervention for pregnant and postpartum women living HIV. The peer intervention is designed to increase self-efficacy, social support, self-regulatory behaviors, and outcome expectancy in order to improve retention in care and viral suppression postpartum. The intervention will consist of face-to-face prenatal educational sessions, starting in early third trimester, and postpartum sessions scheduled up to three months postpartum.
The aim of this study is to examine the utility of neuroimaging technique to evaluate pre-exposure prophylaxis (PrEP) promotion messages for men who have sex with men (MSM) at risk of HIV in Baltimore.
Persons with HIV, even those well-treated, are at increased risk for heart disease when compared to the general population. Two hormones called aldosterone and brain natriuretic peptide (BNP), which have been shown to be abnormal in HIV, may be associated with inflammation as well as early changes in structure and function of the heart. This study is being conducted to evaluate whether therapies to block aldosterone and increase BNP levels may reduce the burden and progression of heart failure to improve cardiovascular health.
In summary, in this project the investigators propose to study the proviral DNA genotyping to implement a lower cost and wider than the commercial systems currently in use, in order to analyze all HIV genes that are therapeutic targets of antiretroviral drugs. Using HIV proviral DNA we can obtain information for: HIV-1 Viral Tropism, Mutations associated to Integrase Inhibitors, Mutations associated to Transcriptase reverse Inhibitors, Mutations associated to Protease Inhibitors, and Mutations associated to GP41 Inhibitors. Along with this the investigators propose to validate the proviral DNA as starting material for genotyping which is independent of the patient's viral load and achieve a greater number of patients living with HIV have access to this important test that is essential in monitoring the HIV infection. 3.2 RESEARCH QUESTIONs Is proviral DNA a genetic compartment suitable for carrying out a genotypic resistance test in patients with low or undetectable viral load? Does proviral DNA have the same clinical validity that RNA? 3.3.- HYPOTHESIS A resistance genotyping test carried out by Proviral DNA detects the same mutations associated to resistance that viral RNA. 3.4.- OBJECTIVES: General/Specific General objective Develop a methodology to assess the proviral HIV-1 DNA or RNA as the genetic material for genotyping assays in genes that are targets of pharmacological interest as TR reverse transcriptase and protease (PRO), Integrase or GP41 Inhibitors and HIV tropism. Specific Objectives 1. Carry out genotyping by proviral DNA and compare it with the same genes genotyping performed with viral RNA. 2. Once the correlation between proviral DNA and RNA has shown, standardize a method to use the technique for clinical use in monitoring HIV patients according to each patient's needs. RNA for patients with viral load above 1,000 copies/mL. Proviral DNA for patients with low or undetectable viral load.
As undiagnosed and untreated hypertension is one of the largest drivers of cardiovascular disease in sub-Saharan Africa approaches are needed to optimize the hypertension care cascade. The HIV treatment platform in low and middle income countries provides a robust, scalable foundation to address other chronic care priorities, such as hypertension. This proposal will evaluate an evidence-based intervention designed to improve chronic care services (the Systems Analysis and Improvement Approach (SAIA)) for hypertension detection and management in people living with HIV, and will build evidence on how to achieve rapid, sustainable and scalable improvements in services that can dramatically improve population health in resource-limited countries.
