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.
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 (ERβ), 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.
The aim of the study was to determine the knowledge attitudes, behaviours and practices of sex workers regarding HIV in Martinique, guadeloupe and Saint martin.
determine the Knowledge attitudes behaviours and practices regarding HIV of men who have sex with men in the French Antilles and French Guiana
Pre-exposure prophylaxis (PrEP) with Truvada™ (tenofovir/emtricitabine), in which an HIV-uninfected individual at high risk for contracting HIV takes antiretroviral medications (one pill daily) to maintain blood and genital drug levels sufficient to prevent HIV-1 acquisition, has been validated in several large international trials that have included men who have sex with men and transgender women, heterosexual men and women, and people who use injection drugs, as a potential HIV-1 prevention strategy. HIV prevention interventions such as this, if adequately disseminated and implemented broadly, may help to curb new HIV infections, reduce HIV-associated morbidity and mortality, and reduce health disparities in HIV rates among the most at-risk individuals. Assuring adherence to a daily dose of PrEP is critical for effective protection against HIV infection. A urine-based test to measure PrEP medication levels in the body represents a non-invasive technique to assess adherence and ultimately improve PrEP's protective ability. TAF/FTC (Descovy™) is a new medication under study for HIV prevention to see if it is as effective as Truvada™. This study is testing whether a urine test can detect this medication in urine.
Background: Cytomegalovirus (CMV) infection is usually observed among patients with HIV infection. No study to date has investigated the impact of CMV infection on HIV viral load decay during antiretroviral therapy. Methods: 345 consecutive HIV patients coinfected (N=300) or not (N=45) with CMV were enrolled. Clinical, biological and virological data were collected from HIV antiretroviral therapy initiation to the day of HIV viral load undetectability if any.
Despite advances in HIV/sexually transmitted infection (STI) prevention, Black youth account for the largest number of new HIV infections among heterosexual youth. Having a mental illness contributes to HIV/STI risk among heterosexually active Black youth, as some use sex as a means to manage psychological distress, regulate emotions and receive validation or acceptance. Current intervention models focus on cognitive-behavioral strategies to reduce risk among adolescents; however, these approaches in isolation do not address the psychopathology that further potentiates risk behaviors among adolescents with mental illnesses. This randomized controlled trial evaluated the effects of "Project GOLD", a theoretically-driven, gender and culturally relevant, developmentally and psychologically appropriate HIV/STI risk reduction intervention on the sexual behaviors of Black male and female adolescents in Philadelphia (aged 14-17). In addition to evidence-based HIV/STI preventions strategies (e.g., role playing), Project GOLD includes unique emotion regulation content to address the relationship between psychological distress and HIV/STI risk behaviors. The research team approached and screened 704 adolescents. Eighty-two participated in the elicitation research activities (e.g., focus groups, intervention dress rehearsal). Another 173 underwent a structured demographic and mental health diagnostic interview to determine RCT eligibility. Project GOLD was then tested with 108 Black youth in comparison to a general health promotion control condition (intervention n = 52; control n = 56). Youth who were not in psychiatric treatment were also included, as the investigators hypothesized that they would also benefit from the targeted psychoeducational content; post-hoc analyses examined differences in the intervention effects based on whether or not youth were in psychiatric treatment. The intervention had high feasibility and acceptability. These findings underscore the need to encourage HIV/STI testing and risk reduction efforts among Black youth, including those with mental illnesses.
