HIV treatment optimism and crystal methamphetamine use and initiation among HIV-negative men who have sex with men in Vancouver, Canada: A longitudinal analysis.

ABSTRACT: BACKGROUND:Treatment as Prevention (TasP) leading to increased HIV treatment optimism among men who have sex with men (MSM) has been previously associated with behavioural risk compensation, though not yet via crystal methamphetamine (CM) use. Among HIV-negative MSM in a TasP environment, this study aimed to investigate the prevalence of recent CM use over time, examine the association between HIV treatment optimism and CM use and initiation, and identify correlates of recent CM use and predictors of CM initiation. METHODS:Using data from a prospective behavioural cohort study of sexually active MSM in the Vancouver area, we used multi-level generalized mixed effect models to evaluate temporal trends in CM use, univariable and multivariable logistic regression to identify covariates of recent CM use, and univariable and multivariable survival analysis to identify predictors of CM initiation. RESULTS:Of 497 HIV-negative cohort participants, 10.3% reported any recent CM use at enrollment. From 2012-2016, there were no statistically significant temporal trends in overall CM use or with routes of administration. In multivariable logistic regression analyses, HIV treatment optimism was not associated with recent CM use (not retained in final model) or CM initiation (aHR?=?1.06, 95% CI:0.98-1.15). Significant correlates of CM use include recent gamma-hydroxybutyrate (GHB) and ecstasy use, and having received/given drugs for sex. CONCLUSIONS:Among HIV-negative MSM in Vancouver, HIV treatment optimism does not appear to be independently associated with CM use or initiation of use, though use of CM was both prevalent and stable over time.

Project description:OBJECTIVES:In British Columbia, Canada, syphilis is at record-high rates, with over 80% of cases in 2017 seen in gay, bisexual and other men who have sex with men (GBM). The syphilis epidemic is of particular concern for those living with HIV, since syphilis may lead to more serious complications in this population. We sought to explore syphilis-related knowledge and attitudes around biomedical prevention options for syphilis, with the goal of informing effective strategies to prevent syphilis. DESIGN:We conducted a qualitative study consisting of in-depth, individual interviews from December 2016 to June 2017. Our interviews focused on participants' knowledge about syphilis and perceptions regarding syphilis pre-exposure prophylaxis (PrEP). Interviews were analysed using Grounded Theory. PARTICIPANTS:Twenty-five GBM were interviewed (64% white; median age: 43 years), including men living with HIV and/or with a history of syphilis. SETTING:Vancouver, British Columbia. RESULTS:Five interrelated themes emerged. First, GBM were aware of the local syphilis epidemic. Second, syphilis-related knowledge differed according to syphilis and HIV serostatus. Third, competing ideas emerged regarding men's concerns about syphilis. While our participants expressed concern about getting syphilis, they also described the importance of sexual pleasure. Fourth, many participants said that syphilis was not perceived to be alarming; preventing HIV infection remained a primary concern for many. Finally, while syphilis PrEP was appealing to those living with HIV or a prior syphilis diagnosis, others were concerned about antibiotic resistance, cost and side effects. CONCLUSIONS:Our participants organised their safer sex strategies around HIV, not syphilis. Although syphilis-related knowledge was relatively high among GBM living with HIV and those with a prior syphilis diagnosis, this knowledge did not appear to be related with safer sexual practices, such as increased condom use. This work highlights the importance of examining other potential prevention solutions, such as syphilis PrEP.
