Metabolic syndrome is a constellation of risk factors for cardiovascular disease and type 2 diabetes mellitus which frequently occur together. Data is emerging suggesting metabolic syndrome causes brain disease by contributing to blood vessel damage and inflammation. People living with HIV (PLWH) are at high risk and the investigators will perform a pilot study of the well-known type 2 diabetes drug metformin to treat this blood vessel damage and inflammation in PLWH.
The investigators broadly aim at determining barriers and facilitators to PrEP uptake and adherence and retention among the study participants. The investigators have the following specific objectives of determining: (1) the PrEP knowledge levels, attitudes, practices, and user experiences among injecting and sexual partners of PWID in Nairobi County (2) the socio-demographic, behavioural, and structural factors hindering the uptake of PrEP among PWID's sexual and injecting partners in Nairobi County; and (3) the effect of a theory-guided behavioural intervention (PrEP-UP) utilizing peer outreach and navigation on the uptake of PrEP by the study participants. The investigators hypothesize that: PWID's injecting and sexual partners in Nairobi City lack PrEP knowledge, and have poor attitudes practices, and user experiences about PrEP; less than 50.0% of the PWID's sexual and injecting partners in Nairobi County have socio-demographic, behavioural and structural factors hindering their uptake of PrEP; and a theory-guided behavioural intervention (PrEP-UP) utilizing peer outreach and navigation has no effect on the uptake of PrEP by the study participants.
Autophagy and apoptosis are natural cellular mechanisms which consist for the first in a recycling and elimination process of potentially toxic cellular waste, and for the second in a process of cellular suicide when it becomes abnormal and "not" repairable, notably by autophagy. A deficit in autophagic function at the cellular level can lead to chronic inflammation and accelerated cellular senescence. Apoptosis is a beneficial phenomenon because it eliminates abnormal cells that could endanger the organism if it survives (e.g. karyotypic atypia). Uncontrolled, it can be deleterious if apoptosis is hypo or hyperactive.
Following the ANRS-APSEC survey, AMEP-EHVA T02 is a longitudinal social science study that will explore the experience of people living with HIV (PLWH) who were offered to participate in the European randomized phase II placebo-controlled trial of vedolizumab with or without therapeutic HIV MVA vaccine including antiretroviral treatment interruption (EHVA T02/ANRS VRI07).
COVID-19 has emerged as global pandemic during the past few months, with an unprecedented impact on public health, and society more generally. Virus epidemiology is poorly understood, as are factors influencing the diverse clinical picture. To date most cases have been seen in high income countries and consequently COVID-19 diagnostics and research have mainly been set-up in these settings. Outstanding questions include an understanding of how the virus spreads and how it causes pathology. A particular gap in current knowledge is the effect of HIV and tuberculosis (TB) on the outcomes of COVID-19 disease as these two conditions impair the host immune response to other infectious disease. Understanding how these three pandemics interact is crucial. We have developed a proposal that will answer critical questions concerning COVID-19 disease epidemiology in the context of low resource countries with high burden of poverty, and in the presence of high rates of TB and HIV, namely, Namibia and Botswana. Given that there are currently few cases of COVID-19 diagnosed in both countries, the project will document how the virus spreads within susceptible populations. The development of this proposal is highly collaborative and interdisciplinary, with investigators from Namibia and Botswana working closely with colleagues in Europe. We will also work with an NGO in Namibia, Health Poverty Action, to support rapid implementation. The project includes two studies that will be conducted sequentially. The first study will follow the WHO protocol for household transmission investigations in the context of COVID-19. It will explore transmission frequency and describe the clinical spectrum of disease. Samples collected will also serve as basis for COVID-19 molecular epidemiology and host immunological response. The second study will evaluate the presentation, diagnosis and clinical characteristics of individuals presenting to sentinel health facilities in both countries. The project will have a strong laboratory strengthening component which will enhance COVID-19 laboratory and research capacity. This will include the development of skills and knowledge for diagnostic testing and COVID-19 sequencing and will build scientific and research capacity. The findings from this project will provide robust data to assist in guiding national responses to COVID-19 in both countries as well as assisting with our understanding of the pathogenesis of the virus in the context of TB and HIV, in turn providing vital information on how to deliver clinical care and how to design therapeutics and vaccines.
We will use a web-based system in order to deliver a text messaging-based intervention and assess the efficacy to increase retention in HIV care among HIV+ gay men in Peru.
French Guiana, a French territory located in South America, faces several social challenges including financial insecurity, unemployment and significant immigration. The degraded living conditions of migrants arriving in the territory are likely to put them in a situation of sexual vulnerability that could increase their risk of acquiring HIV (human immunodeficiency virus). This study proposes to conduct a survey of a group of people living with HIV in French Guiana who were born in Haiti and a group of Haitian people who are not HIV positive. With the help of interviewers who speak Haitian Creole, it will allow us to better understand the life paths of people from Haiti and their periods of vulnerability. Investigators will also focus on the use of testing and retention in care for those living with HIV. The results of this work will allow for the mobilization of resources and better adjustment of social support, prevention and care interventions implemented in French Guiana for migrant populations and/or those in precarious situations.
The U.S. Department of Health and Human Services (HHS), through the National Institutes of Health (NIH), published Final Human Immunodeficiency Virus (HIV) Organ Policy Equity (HOPE) Act Safeguards and Research Criteria for Transplantation of Organs Infected With HIV. All such transplants must occur under an institutional review board (IRB) approved research protocol that is compliant with federal regulations governing human subjects research. This is an investigator-initiated, observational prospective study of solid organ transplantation utilizing HIV-positive donors in HIV positive recipients. Stable HIV-infected adults in need of a solid organ transplant (kidney) who meet standard and study specified HIV criteria for organ transplantation will be offered enrollment in the study. Deceased donors (kidney) and living donors (kidney) will be utilized in this protocol. The goal of this research is to increase knowledge about the safety, efficacy, and effectiveness of solid organ transplantation (SOT) utilizing HIV-positive donors in HIV-positive recipients.
This study is part of a national vision to fight against serophobia and support society towards more ethical and benevolent practices vis-à-vis aging and specific populations. The main objective of this study is to assess over the past five years the prevalence of people living with the Human Immunodeficiency Virus (HIV) aged 60 years and over and its evolution within the Paris Region medico-social structures
