PrEP use and Chemsex
Is “on-demand” PrEP a suitable tool for MSM who participate in Chemsex? From ANRS-Ipergay.
This was in an IPERGAY sub-study of 331 participants during the open-label extension (OLE) phase of the study who reported drug use during at least one sexual encounter.
2 monthly data was collected regarding drug and alcohol use, sexual behaviors and PrEP adherence during the participant’s most recent sexual encounter(s) and analyzed with a multivariate regression model. PrEP use was self-reported by participants.
Among the MSM participants, 29% reported Chemsex at least once during the follow up period and16% reported chemsex at all visits.
Socio-demographics between those labeled chemsexers were not different from those labeled non-chemsexers, other than a higher use of anxiolytics in chemsexers.
After adjustment, chemsexers were found to be more likely to use PrEP (OR (95% CI = 2.18 (1.04; 4.49)) and less likely to use condoms (p< 0.001)
Of note, when MSM reported chemsex during their most recent sexual encounter there was a grater likelihood of receptive anal sex, hardcore sexual practices, casual sexual partnerships and a higher perception of risk. All p-values <0.001
This important and interesting sub-study suggests that PrEP may therefore be a suitable tool for HIV prevention people practicing chemsex.
