Evolution of illicit opioid use among people with HIV infection in St Petersburg, Russia, in the period 2004-2015.

OBJECTIVES: In the late 1990s, when the current Russian opioid epidemic began, illicit opioids used in Russia consisted almost exclusively of heroin. The type of opioids used has evolved in the early 21st Century. The objective of this study was to describe the evolution of illicit opioid use among people living with HIV (PLWH) reporting recent opioid use in St Petersburg, Russia. METHODS: We examined baseline data from four research studies conducted in the period 2004-2015 that included PLWH who used opioids [Partnership to Reduce the Epidemic Via Engagement in Narcology Treatment (PREVENT; 2004-2005; n = 17), HIV Evolution in Russia-Mitigating Infection Transmission and Alcoholism in a Growing Epidemic (HERMITAGE; 2007-2010; n = 281), Linking Infectious and Narcology Care (LINC; 2013-2014; n = 119) and Russia Alcohol Research Collaboration on HIV/AIDS (Russia ARCH; 2012-2015; n = 121)] and reported recent use of heroin and other opioids. RESULTS: Although these studies spanned more than a decade, the participants represented similar birth cohorts; the mean age was 24.5 years in 2004 and 33.3 years in 2014. The use of opioid types, however, evolved across cohorts, with the use of any illicit drug other than heroin increasing from 6% [95% confidence interval (CI) 000.2, 29%] in PREVENT (2004-2005) to 30% (95% CI 25, 36%) in HERMITAGE (2007-2010) to 70% (95% CI 61, 78%) in LINC (2013-2014) to 77% (95% CI 68, 84%) in ARCH (2012-2015). Any heroin use consistently decreased over the 10-year period in the cohorts, from 100% (95% CI 80, 100%) in 2004-2005 to 54% (95% CI 44, 63%) in 2012-2015. CONCLUSIONS: Among PLWH who use opioids in St Petersburg, Russia, illicit use of opioids other than heroin appears to be more common than heroin use.

Speaking the truth: an analysis of gender differences in serostatus disclosure practices among HIV-infected patients in St Petersburg, Russia.

The Russian HIV epidemic is primarily fuelled by injection drug use, but heterosexual spread may be playing an increasing role in transmission. Government-funded AIDS clinics provide most HIV treatment in Russia, and represent an important contact point between the medical community and infected population. Little is known about the population actively seeking HIV treatment. To describe demographics, perceived mode of acquisition and serostatus disclosure practices of HIV-infected individuals seeking treatment in St Petersburg, Russia, we conducted a cross-sectional study of 204 HIV-infected patients presenting to the St Petersburg City AIDS Center between May and June 2007. Mean age of respondents was 28 years old, 51% were women and two-thirds (67%) reported a history of injection drug use. Men were more likely to report injection (62% versus 45%) while women were more likely to identify sexual transmission (45% versus 32%) as their perceived infection route. Predictors of serostatus disclosure were female gender, married status and higher education. Women represent half of all patients seeking HIV treatment in St Petersburg, and are more likely than men to have disclosed their HIV-positive serostatus to sexual partners. While this population may not represent the burden of HIV disease in Russia, it is an important target group for secondary prevention.
