Filter by:Get Connected (GC) is an online brief intervention that employs individual and systems-level tailoring technology to reduce barriers to HIV prevention care (e.g., HIV/STI testing, PrEP) for YMSM. The deployment of GC through a mobile-friendly WebApp seeks to optimize online interventions' acceptability, accessibility, availability, long-term affordability among youth. The investigators will enroll self-reported HIV-negative or sero-status unaware, sexually active YMSM (ages 15-24) across three cities and randomize them into the GC intervention condition or to an attention-control condition. Assessments will be collected at 30 days and at 3, 6, 9 and 12 month follow-up.
Phase 4 study to evaluate the immunogenicity and Safety of the 17DD Yellow Fever vaccine in HIV infected individuals, compared to non-HIV-infected individuals. Main objective: To compare the proportion of seroconversion and the geometric mean of neutralizing antibodies 30 days and 365 days after vaccine. Secondary objectives: To evaluate whether the titles of neutralizing antibodies are associated with CD4 lymphocyte counts, CD8 lymphocyte counts, CD4 nadir, HIV viral load and use of antiretroviral therapy. To assess the yellow fever vaccine viremia at day 10 after vaccine.To compare the incidence of adverse events in HIV-infected and non-HIV-infected individuals.
This non-interventional study aims to determine whether there is a correlation between the Fc receptor polymorphism (FcR) and the course of the disease following HIV infection.
The spectrum of reported autoimmune phenomena in HIV infected patients is unexpectedly broad and - owing to the current efficacious treatment regimes - increasing. The likelihood of the occurrence of autoimmune phenomena correlates with a high CD4 count, consequently they are found most frequently soon after infection or after immune reconstitution. It is likely that recent developments, namely the recommendation to treat all patients regardless of their CD4 count, may lead to a further increase in autoimmune phenomena in HIV infected patients. In contrast to the abundance of data of rheumatological and hematological autoimmune disease in HIV infected patients, no systematic study exists which has analyzed the prevalence of autoimmune blistering disease and/or associated autoantibodies in these patients. The investigators therefore intend to determine the prevalence of selected autoantibodies in our HIV cohort in relation to uninfected controls. According to recent guidelines, all HIV infected patients should receive anti-retroviral treatment at the earliest time point possible, making the restoration of the immune system more likely and leading to a further alignment of the life expectancy relative to age matched, uninfected controls. As a consequence, the incidence of AIBD, especially of bullous pemphigoid, for which age is the single most important risk factor, may rise. In total, knowledge about the prevalence of AIBD specific auto antibodies might be supportive in the diagnosis of these conditions in the future.
This study will evaluate the effect of ledipasvir/sofosbuvir (LDV/SOF) treatment on the pharmacokinetics (PK) and renal safety of tenofovir in the form of tenofovir alafenamide (TAF). Subjects living with human immunodeficiency virus (HIV) who are receiving tenofovir-based antiretroviral therapy (in the form of tenofovir disoproxil fumarate [TDF]), and are also taking a ritonavir- or cobicistat-boosted protease inhibitor will be invited to participate. The study will consist of five visits: a screening visit, three abbreviated 4-hour pharmacokinetic visits, and one end-of-study follow-up visit. Subjects will also be asked to use a Wisepill device, which will track medication adherence throughout the study.
HIV is associated with a pattern of neurocognitive deficits, metabolic dysfunction, and an elevated risk for cardiovascular disease (CVD), phenomena that remain untreated despite the use of medications to control the disease. This proposal will examine the effect of a personalized, automated, interactive mobile phone text message intervention (iSTEP) designed to increase moderate physical activity (PA), decrease sedentary behavior (SB), and promote a healthy Mediterranean-style diet (MedDiet) in persons living with HIV (PLWH). The investigators propose that participants who receive the iSTEP intervention will increase the amount of physical activity, improve their diet, show a reduction in risk factors for CVD, and exhibit improved neurocognitive performance.
A phase 1/2a clinical trial to evaluate the safety and immunogenicity of ALVAC-HIV (vCP2438) and of MF59®- or AS01B-adjuvanted clade C Env protein, in healthy, HIV-uninfected adult participants
Interventional HIV prevention strategy based on pre-exposure prophylaxis (PrEP) with Truvada® for people in the Île-de-France area (or Paris region) who don't have HIV but who are at high risk of becoming infected with HIV (men who have sex with men (MSM), transgender men and women, heterosexual men and women, sex workers, migrants) in combination with overall prevention services (communautary-based or educational counselling; addiction, social and psychological care; condoms and lubricating gel; clean injection equipment; sexually transmitted diseases (STD) screening and treatment; hepatitis A virus (HAV), hepatitis B virus (HBV) and hepatitis C virus (HCV) vaccinations and post-exposure treatment of HIV infection as soon as possible after diagnosis using an antiretroviral combination recommended by the French Guidelines on HIV treatment). The individual benefit being already demonstrated in clinical trials, the aim is to demonstrate the public health impact of the interventional HIV prevention strategy by reducing the risk of getting HIV-1 infection of at least 15% of new diagnosis of HIV infections among MSM/transgender in the Ile-de-France area after a 3-year period.
The study is a Phase 1, randomized, double-blinded, placebo-controlled, sequential single dose escalation safety, tolerability and pharmacokinetic study of subcutaneous and intramuscular TMB-607 administered to HIV-negative volunteers.
This study will assess and characterize the variability observed in the response to darunavir therapy, an antiretroviral medication used against the Human Immunodeficiency Virus (HIV). More specifically, it aims to quantify variations in the drug's blood concentrations and determine the sources of such variability, both genetic and non-genetic. In light of this information, current dosage guidelines will then be reviewed.
