Filter by:The CASCADE-trial is a two-armed open-label randomized controlled trial conducted in rural Lesotho. Participants who were tested HIV-positive during community-based HIV testing and counseling campaigns are randomized to the intervention or control arm. Allocation is 1:1 with parallel assignment. Participants in the control arm follow the standard of care after a community-based HIV test result: They are referred to the nearest clinic where they will receive baseline laboratory testing and adherence counseling. After at least 2 clinic visits for adherence counseling they can start anti-retroviral therapy (ART). After ART-initiation they have to attend monthly follow-up at the clinic for drug refill. Individuals randomized to the intervention arm are proposed same day community-based ART initiation combined with less frequent follow-up visits. The primary outcomes are linkage to care at 3 months and viral suppression at 12 months after having tested HIV-positive during the community-based HIV testing and counseling campaigns.
The overarching goal of the proposed study is to determine effective outreach methods designed to recruit and improve acceptance of high-risk HIV-negative YBMSM to initiate PrEP and to identify and modify psychosocial and structural predictors of PrEP acceptance. Specifically, the objective of this pilot study is to test the feasibility of a motivational interview-based intervention designed to improve PrEP acceptance among YBMSM.
Clinical hypotheses: The increasing number of people aging with HIV is a matter of fact. Differences in prevalence of comorbidities between the general population and HIV-positive patients are mainly driven by duration of HIV infection rather than chronological age of HIV+ patients. People aging with HIV display heterogeneous health conditions. Host factors and duration of HIV infection are associated with increased risk of MM, independently from chronological age and these factors are responsible of the prevalence difference of comorbidities and MM in comparison to the general population. Objectives: The study objective is to assess the prevalence of, and risk factors for, individual co-morbidities and multi morbidity (MM) between HIV-positive patients with similar duration of HIV infection, but 30 years difference. We compared estimates across both groups to a matched community-based cohort sampled from the general population.
Anti-HIV drugs cut down the number of serious infections that people with HIV get. However, some subjects taking anti-HIV drugs do not achieve adequate cluster of differentiation 4 (CD4) recovery and decrease in elevated cluster of differentiation 8 (CD8) cells. Such patients with a low CD4/CD8 ratio remain at risk for developing acquired immune deficiency syndrome (AIDS) and non-AIDS-related complications. Two of the most important factors associated with low CD4/CD8 ratio include: the persistence of HIV on ART and inflammation. Metformin, the most widely used medication to treat type 2 diabetes, is well tolerated with minimal side effects. It has been linked to anti-aging and weight reducing properties in non-diabetic persons. Because of its ability to improve immune functions, metformin could be a promising addition to ART in HIV patients. It is also reported to change the composition of microbes in the gut which may improve inflammation. PURPOSES OF THE STUDY The purposes of this study are to find out if: 1. metformin can be combined with anti-HIV drugs to reduce the amount of hidden virus in the body; 2. metformin can be combined with anti-HIV drugs to improve immune function. 3. metformin can be combined with anti-HIV drugs to impact CD4 T cell count and CD4/CD8 T cell ratio during treatment and after its discontinuation 4. metformin can change the composition of the bacteria in the gut which may improve inflammation. For this purpose, the investigators will add metformin at the usual antidiabetic dose for 12 weeks for patients receiving stable ART, having a CD4/CD8 ratio below 0.7. Approximately 22 participants will be enrolled in this study at the Chronic Viral Illness Service of the McGill University Health Centre, the Ottawa Hospital and the Maple Leaf Medical Clinic (Toronto). This study will last about 24 weeks; metformin treatment will be for 12 weeks. In order to be eligible for the study, the participants must be 18 years of age or older, have an undetectable viral load (the quantity of the HIV virus in the blood must be less than 50 copies/ml) for at least 3 months and have a CD4/CD8 ratio of less than 0.7. All participants will also be asked to give blood and stool samples and optional colon mucosal biopsy samples (before and after metformin supplementation) to study the size of the viral reservoir and the amount of T cell activation and changes in gut microbiota composition.
The objective of the study is to evaluate the feasibility and interest of a HIV quarterly preventive global care for men who have sex with men (MSM) in sub-Saharan Africa to help reducing HIV incidence in this key population, their female partners, and the general population. This interventional, open label, multicenter, multidisciplinary cohort study will be conducted in Burkina Faso, Ivory Coast, Mali and Togo. All participants will receive a HIV quarterly preventive global care including: i) data collection on health status, symptoms of sexually transmitted infections (STI) and sexual behavior, ii) a clinical examination, iii) STI diagnosis and treatment, iv) counselling adapted for MSM, and v) the provision of condoms and lubricants.
Populations from Sub-Saharan Africa represent one of the most dynamic immigration flows in France and are among the most exposed to HIV infection and hepatitis B. The Parcours study aims to understand, among sub-Saharan African migrants, how social and individual factors combine in the course of migration and settlement in France, and influence the risk of infection, access to prevention and care, and the effectiveness of care for both HIV and hepatitis B diseases. The research was conducted in Ile-de-France, where 60% of sub-Saharan African migrants reside. It consists in a cross-sectional observational survey, using a life-event history approach that reproduces the sequence of different life and health events, and contributes to explain the present situation (type of disease management, patient's quality of life) in light of all the elements of the past trajectory (administrative, familial, socio-economic, professionals). A representative survey was conducted between February 2012 and May 2013 in health care facilities in Ile-de-France, among three groups of migrants from Sub-Saharan Africa: a group living with HIV, a group living with chronic hepatitis B and a group who has neither of these diseases. For each group, stratified random sampling was used. The survey was conducted in 24 hospital services providing HIV care, 20 health care facilities providing hepatitis B care, and 30 primary health care facilities. Were eligible all patients attending these health care facilities, born in a Sub-Saharan African country and with Sub-Saharan African citizenship at birth, aged 18 to 59 years, with an HIV diagnosis (HIV group) or chronic hepatitis B diagnosis (hepatitis B group) more than three months prior or not diagnosed with HIV or chronic Hepatitis B (reference group). Among the patients offered participation, 926 HIV-infected patients, 779 patients infected by hepatitis B, and 763 patients without these two diseases participated in the study. For all participants, detailed information on socio-demographic characteristics; migration and life conditions in France; social, sexual and reproductive life history; and screening and care history were collected using a life-event history questionnaire administered face-to-face by a specialized interviewer. Health care professionals documented clinical information from the medical records. Data was collected anonymously.
The TEACH randomized controlled trial will test the effectiveness of a collaborative care intervention directed towards physicians who provide care for HIV-infected persons to improve the quality of care for prescribing chronic opioid therapy (COT) for pain and reduce the misuse of prescription opioids among HIV-infected persons.
India has the world's third largest HIV epidemic and men who have sex with men (MSM) are an identified high risk group. MSM in India face unique psychosocial stress underlying the context of HIV risk. To maximize the potential impact of an HIV prevention intervention, the purpose of this study is to test, in a two-arm randomized controlled efficacy trial, a behavioral intervention that addresses both psychosocial / contextual stress and reducing participant's risk for HIV.
The purpose of this study is to determine whether regularly scheduled HIV sensitization text messages (SMS) are effective in increasing HIV testing rates among young women in Kenya.
The TEACH patient cohort will characterize a clinic sample of HIV-infected patients on chronic opioid therapy (COT) by describing basic demographics and health status, including characteristics of pain (severity and interference), aberrant behaviors/misuse of COT, substance use and trust/satisfaction with providers. In addition, data on a subset of participants will be used to supplement analysis of secondary outcomes for the TEACH randomized controlled trial (RCT), an intervention study directed at COT providers (outlined in a separate Clinical Trials Protocol Registration and Results (PRS) summary).
