Filter by:HIV transmission remains a significant public health concern, especially among men who have sex with men (MSM). Condomless anal intercourse (CAI) continues to be the major route of transmission for MSM. Thus, to reduce the incidence of HIV, it is critical to identify how contextual risk factors influence CAI and develop behavioral strategies that modify risk factors directly or reduce their influence on behavior. This study will examine the mechanisms through which one of the central contextual risk factors, heavy drinking, influences sexual decision processes in the natural environment and test the benefit of a brief intervention designed to reduce sexual risk behavior among those who engage in heavy drinking.
Chronic immune activation present in aviremic people living with HIV under treatment promotes the onset of insulin resistance and metabolic syndrome, paving the way for the comorbidities that are currently the main causes of morbidity. This activation continues despite effective antiretroviral therapy. In the ACTIVIH study (NCT02334943) the analysis of 68 AI markers allowed classification of 120 aviremic PLHIV under treatment for at least 2 years according to 5 different immune activation profiles. Among these 5 profiles, Profile 2 was characterized by high blood pressure figures, high waist sizes, low HDL-cholesterol levels, high triglyceridemia, and especially hyperinsulinemia. Several studies have shown that the digestive microbiota of this population is less rich and less diverse than that of healthy subjects. However, the digestive microbiota and in particular bacterial proteins and metabolites seem to play a key role in immune activation in people living with HIV. Finally, the digestive microbiota has already been shown to have an impact on insulin sensitivity. The study investigators hypothesize that a particular digestive microbiota could promote the appearance of Profile 2. This microbiota could be the cause of digestive dysbiosis leading to intestinal inflammation, digestive permeability and bacterial translocation.
Both HIV infection and Covid-19 are associated to cognitive and psychiatric impairment, like anxiety and depression. These disturbs are well-known in HIV infection and partially characterized in Covid-19.
This study will adapt the evidence-based intervention, Healthy Relationships, and then assess its feasibility using a pilot randomized controlled trial with HIV-positive MSM living with HIV in Eastern Cape, South Africa
This couples-based, digital health intervention project is serostatus neutral and seeks to determine efficacy for: a) use and adherence to evidence-based HIV/STI prevention-care strategies; b) creation and adherence to a tailored prevention-care plan; c) creation and adherence to a tailored sexual agreement; and d) improvements in other relationship dynamics among male couples who are in a relationship (defined as greater than 3 months or more).
The goal of this clinical trial is to test an intervention to reduce stigma among people living with HIV who use opioids and cocaine. The main question it aims to answer is: - Does reducing internalized stigma about HIV and/or drug use lead to improved HIV care outcomes? After a year spent adapting an existing intervention to be applied specifically among people living with HIV who use substances, 70 participants will be randomized to receive either treatment-as-usual or the newly adapted intervention. The intervention itself will consist of less than ten group-based meetings to discuss and work through the stigmas people commonly associate with HIV and/or drug use.
The goal of this treatment study is to learn about the mental health, substance use and physical health outcomes associated with participating in the EASE holistic behavioral health and wellness program for individuals identifying as LGBTQ+ and/or living with HIV. The main questions it aims to answer are: 1. Do important health outcomes, including substance use, mental health and social support related outcomes of individuals living with HIV and/or identifying as LGBTQ who participated in the holistic behavioral health and wellness program change after study participation? 2. Does a tailored approach to meet the specific needs of different subpopulations including 1) older (40+) PLWH and/or LGBTQ individuals with or at risk for additional health comorbidities and 2) PLWH and/or LGBTQ young adults (18-40) improve health outcomes including improvement in health and health behaviors . Participants will be asked to: - participate in 6 months of behavioral health treatment tailored to their needs, which may include individual counseling, group counseling, case management, peer support, and related education. - Complete surveys at the time of study entry and 6 months later to measure changes in health outcomes over time.
HIV-infected patients develop comorbidities earlier than the general population. Immune activation with the secretion of pro-inflammatory cytokines would play a major role in the occurrence of these comorbidities. Numerous factors, called risk factors, already identified in the general population and confirmed in patients with HIV virus favor the occurrence of these comorbidities but cannot alone explain the overrepresentation and precocity of these comorbidities in the HIV population. Investigators hypothesize that optimization or simplification with certain classes of antiretrovirals modify the inflammatory response and are predictive factors for the occurrence of comorbidities
The goal of this experimental pneumococcal carriage study is to to characterise rates and determinants of experimental pneumococcal carriage in PLHIV. The main questions it aims to answer are: - can PLHIV be experimentally inoculated with pneumococcus in a safe manner? - what are the immunological determinants of pneumococcal carriage in PLHIV compared to HIV-negative participants? - how do the pneumococcal carriage dynamics differ between PLHIV and HIV-negative participants? Participants will be inoculated intranasally with a controlled concentration of pneumococcus after which they will be monitored for 21 days during which nasal and systemic immune dynamics and pneumococcal carriage dynamics will be evaluated. At the end of the study any participants exhibiting carriage will have the pneumococcus cleared with antibiotics.
Many people living with HIV in southern Africa, specifically Botswana use tobacco products. Using tobacco makes some of the effects of HIV worse and even causes excess deaths. The investigators plan to use an intervention called Screening, Brief Intervention and Referral to Treatment (SBIRT) to help people to quit smoking and also a drug called varenicline. Apart from helping people to stop smoking, the investigators will also test to see how task shifting can be used to help people stop smoking in a sustainable way. Finally, the investigators will estimate the cost of the intervention.
