Abstract : Introduction: CHEMSEX is an emerging trend especially among Men having sex with men (MSM). Since the advent of New Psychoactive Substances (NPS) such as Cathinones, we have witnessed worrying behavioral modifications toward illicit drugs use and high-risk sexual pratices. Consequences are numerous and severe, especially with Slam: Addiction, psychiatric complications, infectious complications linked to sharing soiled material (endocarditis, hepatitis …) and to hard and unprotected anal intercourses supporting STD transmission. Aim: to assess the prevalence of Chemsex over the last 12 months among HIV-MSM inpatients from the University Hospital of Reunion Island, characterize and contextualize this practice. Methods: an observational and transversal study was performed from May to October 2017, involving two centers (North and South) of the University Hospital. A self-reported and anonymous questionnaire was proposed to every HIV-MSM inpatients from both Infectious diseases units. Knowledge about Chemsex, demographics datas, and characteristics of the pratice were collected. Patients clinical features about HIV and Hepatitis B et C were also gathered. Local authorities approuved the study. Results: 177 patients were included over a 19 weeks-period. Prevalence of Chemsex was 27.1%. Lifetime Chemsex raised up to 53.1%. 52% of active Chemsexers were strictly practising on the Island. They were more likely to be drug users (Cannabis) and 70% had had a STD. They had about 17 sexual partners in the year and almost 70% of them reported high risk sexual pratices. Anal intercourses were always protected in only 42% of cases. By decreasing order of consumption, we found : Poppers® (81%), Cannabis (51%), Viagra® (31%), Cocaïne (20%), Ecstasy (15%), GHB/GBL (13%), Crystal meth (11%), Amphetamin (6%), Ketamin (6%), Mephedrone (6%), LSD (3%), Mushrooms (2%) and Heroïn (1%). Half of Chemsexers never associated alcohol and no psychoactive drugs such as Artane® or Rivotril® was reported, although they are frequently misused in Reunion. Slam was reported by 2 patients who represented 1,13% of the study population. Conclusion : Chemsex is a growing concern on Reunion Island. Our results lend us to advocate the need to pursue efforts for better understanding of Chemsex, so to prevent its consequences and develop relevant and proper Heath strategies.
