Filter by:This randomized controlled pilot study of the "Game Changers" program will: 1. Assess the feasibility and acceptability of implementing an HIV prevention advocacy intervention with people living with HIV who are in HIV care, and who will be trained to be advocates of HIV protective behaviors within their social networks. 2. Assess preliminary intervention effects on a) protective behavior of the HIV-positive clients (condom use, partner concurrency/number of partners, engagement in HIV care, ART adherence); and b) diffusion of prevention messages across the network, as assessed by the content and extent of communication with network members about protective behaviors (condom use, partner concurrency/number of partners, HIV testing, engagement in HIV care, circumcision), HIV disclosure, and HIV stigma. 3. Explore characteristics of HIV-positive clients who more effectively engage in prevention advocacy (in terms of socio-demographics, network characteristics, and network position and type of alters receiving advocacy).
R34-funded study to pilot test an intervention to improve coping with discrimination and adherence among Latino men who have sex with men (MSM) living with HIV. The proposed research aims to modify and refine Siempre Seguiré, a culturally congruent cognitive behavior therapy group intervention for HIV-positive Latino men who have sex with men (LMSM), to include strategies for ART adherence and retention in HIV care; and to conduct a small randomized pilot of Siempre Seguiré to examine feasibility and acceptability, as well as to explore preliminary effects on coping responses to discrimination and antiretroviral treatment adherence among LMSM living with HIV.
More than 3 billion people worldwide are at risk of acquiring malaria and pregnant women living with HIV in Africa are at particular risk. An effective prophylaxis regimen capable of preventing malaria and other common perinatal infections would have great potential to improve adverse birth outcomes. The purpose of this randomized controlled trial is to evaluate a new combination prophylaxis regimen in pregnant women with HIV in Cameroon to determine its efficacy and safety.
Optimizing the prevention of mother-to-child HIV transmission cascade minimizes drop offs from one step to the next to maximize the benefits of antiretroviral therapy on maternal health and pediatric survival, growth, and development. This proposal scales-up a health systems intervention (the systems analysis and improvement approach - SAIA) that packages systems engineering methods (including cascade analysis, flow mapping, and continuous quality improvement) and was previously shown to be effective in improving the prevention of mother-to-child HIV transmission cascade. By spreading the SAIA through routine district management structures, and studying the implementation process, this study will build evidence on how to achieve rapid, sustainable and scalable improvements in services that can dramatically improve population health in resource limited countries.
The aim of this study is to evaluate the effect of zinc gluconate and/or selenium yeast supplementation during six months on clinical (glucose, cholesterol, triglycerides, bone mineral density and body composition) and immunological (oxidative stress, CD4+ count and pro-inflammatory cytokines) parameters in a population with HIV diagnosis on antiretroviral treatment.
Tough Talks is a virtual reality based HIV disclosure intervention that allows HIV+ individuals to practice disclosing to romantic partners. Tough Talks allows participants to have the opportunity to practice disclosing using a variety of strategies and experience different outcomes including acceptance, confusion, lack of HIV knowledge, and rejection.
In general, several studies show that adherence to antiretroviral therapy (ART) among men who have sex with men (MSM) is low. Yet, high adherence to ART is essential-not only to improve the quality of life and survival rates among MSM living with HIV, but also to reduce HIV transmission among their partners. Our project aims to address this unmet need through a community-based habit-formation intervention, which incorporates elements of gamification. This intervention will provide MSM living with HIV who have been recently diagnosed and linked to care several tools to develop the habit of taking their medication and overcome disruptive adherence events (DAE) that would otherwise lead to treatment abandonment or lower adherence. Between 2015 and 2017, the investigators conducted a study funded by CONACYT -the Mexican Council for Research-in two Mexican cities to involve MSM living with HIV in the design of an intervention to improve ART adherence. Results from this study show that at the beginning of ART, MSM living with HIV can benefit greatly from a habit-formation community-based intervention that includes support mechanisms to tackle the multiple barriers they face. Using these findings, the investigators created FUERTES, an intervention with two main components: 1) the provision of a simple tool that MSM can access to learn how to develop an habit of taking their ART drugs, and 2) the support of a trained peer with background in psychology to help teach them how to overcome the myriad of barriers they may face in achieving medication adherence. This is a multicentre, parallel, randomized, controlled trial. The project's aim is to pilot-test the intervention and document its implementation. Specifically, the investigators will assess the effect of the intervention on ART adherence among MSM living with HIV at four and ten months. Secondary outcomes include viral load and CD4 cell counts. They will also assess the scalability of the intervention by measuring the costs of the intervention. The duration of the project is two years starting December 2017. The researchers hypothesize that the FUERTES intervention will improve ART adherence among MSM living with HIV starting ART by at least 15%, measured by the medication possession ratio.
There is little known about menopause in African women, whose phenotype differs to Caucasian women, and no data is available on middle-aged black South African men. Accordingly, the study aims to examine the changes in sex hormone levels over the menopausal transition in women, and in men of the same age, and explore the effects on body fat distribution and insulin sensitivity and secretion, dissecting the specific roles of glucocorticoids and inflammatory mediators, in the context of HIV. Research questions and hypotheses: 1. Does the decrease in sex hormones that occur with ageing increase circulating cortisol and/or inflammatory markers, and directly and/or indirectly via increases in central fat mass, decrease insulin sensitivity in middle-aged black South African men and women? Hypothesis: The mechanism underlying the decrease in insulin sensitivity (outcome) associated with the decline in sex hormones (exposure) that occurs with ageing is mediated via an increase in centralization of body fat (mediator), which is due to an increase in inflammation and cortisol production. 2. How does HIV alter the relationship between sex hormones, inflammation and cortisol levels, and subsequently body fat distribution and insulin sensitivity? Hypothesis: HIV infection will exacerbate the effects of the decline in sex hormones with ageing, leading to further increases in inflammation and cortisol production, and a consequent increase in the centralization of body fat and decrease in insulin sensitivity. 3. Does adipose tissue glucocorticoid and inflammatory gene expression differ between pre- and post-menopausal women, with and without HIV, and how do these relate to body fat distribution and insulin sensitivity and secretion? Hypothesis: Adipose tissue estrogen receptor beta (ERĪ²), 11-beta hydroxysteroid dehydrogenase type 1 (11HSD1) activity and pro-inflammatory markers will be higher in post- compared to pre-menopausal women, which will be exacerbated by HIV infection. This will be associated with down-regulation of subcutaneous adipose tissue (SAT) adipogenic genes, increased visceral adipose tissue (VAT), a decrease in insulin sensitivity and secretion, and consequently an increased risk for type 2 diabetes (T2D).
Initially, HCV Informatics (C-IT) will be used to filter the EMR data of the one million people who receive care at Mount Sinai and identify candidates for HCV testing (baby boomers, patients with HIV infection) and candidates for HCV treatment (patients with positive test results for HCV RNA and no record of treatment).once treatment candidates have been identified through this proactive approach, their providers will be directly notified. HCV champions and patient navigators will be used to further lower barriers to the delivery of HCV care. They will be co-located at non-hepatology care sites and will help deliver open-label HCV treatment as part of standard medical care to 500 HIV/HCV co-infected patients and 200 patients with type 2 diabetes.
The efficacy and safety of antiretroviral therapy and the damage caused by chronic inflammation in the presence of the virus has recently lead to the consideration of initiating antiretroviral therapy earlier than what is required to prevent opportunistic diseases. Although there may be subtle differences, all recommended antiretroviral combinations for first-line therapy are considered equally effective. Nevertheless, treatment success requires high levels of adherence, which is linked to tolerability and the minimization of adverse effects. The genes coding the enzymes that are involved in the antiretroviral clearance pathways and the transmembrane transport of drugs are known. These genetic variations can determine the interindividual variations in plasma concentration with the same doses. Both pharmacogenomics (PG) and therapeutic drug monitoring (TDM) may contribute to the individualization of therapy in different chronic conditions through dosing optimization and are associated with a lower risk of concentration-dependent toxicity and potentially greater efficacy. The use of these strategies in the context of antiretroviral therapy is in early stage of development. Following, our main hypothesis is that PG + TDM dose adjustment of efavirenz or atazanavir in the initial antiretroviral treatment of naive patients with HIV infection is non-inferior in terms of efficacy, has improved safety, and shows a better cost/effectiveness profile than the standard approach with non adjusted doses. To evaluate our hypothesis we developed this multicenter randomized clinical trial, where patients from 4 clinical sites in Buenos Aires will be included in the protocol and randomized to standard of care (SOC) or pharmacological adaptation (PA) -PA: PG + TDM. For the pharmacogenomics determination, we developed a multiplex approach including main polymorphisms of CYP2B6, CYP2A6, CYP3A4 y ABCB1 for efavirenz; and UGT1A1, ABCB1 and CYP3A4 for atazanavir. Drug plasma levels will be analyzed with ultra-performance liquid chromatography (UPLC). The main outcomes are to establish the usefulness of PG and TDM in determining the efficacy, safety and cost/effectiveness of a first-line antiretroviral therapy containing either efavirenz or atazanavir in patients with HIV infection who have not received prior antiretroviral therapy.
