Background: Increased rates of sexually transmitted infections (STIs) are reported among men who have sex with men (MSM) and new interventions are needed. We aimed to assess whether post-exposure prophylaxis (PEP) with doxycycline could reduce the incidence of chlamydia or syphilis (or both) and whether the meningococcal group B vaccine (4CMenB) could reduce the incidence of gonorrhoea in this population.

Methods: ANRS 174 DOXYVAC is a multicentre, open-label, randomised trial with a 2 × 2 factorial design conducted at ten hospital sites in Paris, France.

Article Synopsis
  • Chemsex, a trend of drug use linked to sexual activity, is increasing among gay and bisexual men, posing various health risks that necessitate understanding their health-seeking behaviors.
  • A study conducted in Paris provided harm reduction consultations to 96 men, revealing high substance use, significant negative impacts on various life aspects, and a majority found these consultations helpful.
  • The findings highlight the need for comprehensive, multi-disciplinary health interventions for GBMSM engaged in chemsex, emphasizing the importance of accessible harm reduction services.

Background: We evaluated complex pre-exposure prophylaxis (PrEP) situations linked to kidney issues in a cohort of on-demand and daily PrEP users.

Setting: We conducted a single-center retrospective cohort study in France including all PrEP users who received a tenofovir disoproxil (TD)-emtricitabine (FTC) prescription between January 1, 2012 and December 31, 2019 with at least 1 creatinine measurement available before and after PrEP initiation.

Methods: A complex kidney situation (CKS) was defined as an estimated glomerular filtration rate (eGFR) <60 mL/minute/1.

Objectives: We wished to assess time to protection from HIV-1 infection following oral tenofovir disoproxil and emtricitabine (TDF/FTC) as preexposure prophylaxis (PrEP), using ex-vivo rectal tissue infections and drug concentration measures in blood and rectal tissue.

Design/methods: Participants from the ANRS PREVENIR study (NCT03113123) were offered this sub-study after a 14-day wash-out. We used an ex-vivo model to evaluate rectal tissue HIV-1 susceptibility before and after PrEP, 2 h after two pills or 7 days of a daily pill of TDF/FTC.

Background: There are few data available regarding the use of on-demand pre-exposure prophylaxis (PrEP) for HIV prevention. We aimed to assess PrEP effectiveness, adherence, and safety in adults using daily or on-demand PrEP.

Methods: We conducted a prospective observational cohort study (ANRS PREVENIR) at 26 sites in the Paris region, France.
