Objectives: Multiple pathways link gender-based violence (GBV) to HIV and other sexually transmitted infections among women and girls who use or inject drugs. The aim of this article is to synthesize global literature that examines associations among the synergistic epidemics of substance abuse, violence, and HIV/AIDS, known as the SAVA syndemic. It also aims to identify a continuum of multilevel integrated interventions that target key SAVA syndemic mechanisms. Methods: We conducted a selective search strategy, prioritizing use of meta-analytic epidemiological and intervention studies that address different aspects of the SAVA syndemic among women and girls who use drugs worldwide from 2000 to 2015 using PubMed, MEDLINE, and Google Scholar. Results: Robust evidence from different countries suggests that GBV significantly increases the risk of HIV and other sexually transmitted infections among women and girls who use drugs. Multiple structural, biological, and behavioral mechanisms link GBV and HIV among women and girls. Emerging research has identified a continuum of brief and extended multilevel GBV prevention and treatment interventions that may be integrated into a continuum of HIV prevention, testing, and treatment interventions to target key SAVA syndemic mechanisms among women and girls who use drugs. Conclusions: There remain significant methodological and geographical gaps in epidemiological and intervention research on the SAVA syndemic, particularly in low- and middle-income countries. This global review underscores the need to advance a continuum of multilevel integrated interventions that target salient mechanisms of the SAVA syndemic, especially for adolescent girls, young women, and transgender women who use drugs.

Men who have sex with men (MSM) are at high risk for HIV infection. MSM in Central Asia, however, are not adequately studied to assess their risk of HIV transmission. Methods: This study used respondent driven sampling methods to recruit 400 MSM in Almaty, the largest city in Kazakhstan, into a cross-sectional study. Participation involved a one-time interviewer-administered questionnaire and rapid HIV screening test. Prevalence data were adjusted for respondent network size and recruitment patterns. Multivariate logistic regression was used to investigate the association between HIV and selected risk factors, and unprotected anal intercourse (UAI) and selected risk factors. After respondent driven sampling (RDS) weighted analysis, 20.2% of MSM were HIV-positive, and 69.0% had unprotected sex with at least one male partner in the last 12 months. Regression analysis showed that HIV infection was associated with unprotected receptive anal sex (AOR: 2.00; 95% CI: 1.04–3.84). Having unprotected anal intercourse with male partners, a measure of HIV risk behaviors, was associated with being single (AOR: 0.38; 95% CI: 0.23–0.64); very difficult access to lubricants (AOR: 11.08; 95% CI: 4.93–24.91); STI symptoms (AOR: 3.45; 95% CI: 1.42–8.40); transactional sex (AOR: 3.21; 95% CI: 1.66–6.22); and non-injection drug use (AOR: 3.10; 95% CI: 1.51–6.36). This study found a high HIV prevalence among MSM in Almaty, and a population of MSM engaging in multiple high-risk behavior in Almaty. Greater access to HIV education and prevention interventions is needed to limit the HIV epidemic among MSM in Almaty.

Objective: Project Renaissance is a randomized controlled trial of an HIV/hepatitis C virus (HCV)/sexually transmitted infection (STI) prevention intervention conducted in Almaty, Kazakhstan. We hypothesized that couples assigned to the intervention of interest will have lower incidence of HIV, HCV, STIs, rates of unprotected sex, and unsafe injection over the 12-month follow-up period compared with those assigned to an attention control arm. Design: A total of 300 couples (600 participants) where one or both partners reported injecting drugs in the past 90 days were randomized to 1 of 2 arms: (1) a 5-session HIV/HCV/STI prevention intervention (risk reduction: RR) or (2) a 5-session Wellness Promotion (WP) intervention. Results: Over the 12-month follow-up period, assignment to RR compared with WP significantly lowered the incidence of HCV infection by 69% [incidence rate ratios (IRR) = 0.31, 95% (CI) confidence interval: 0.10 to 0.90, P = 0.031]. Although differences were not statistically significant, RR participants had a lower incidence of HIV infection by 51% (IRR = 0.49, 95% CI: 0.16 to 1.48, P = 0.204) and any STI by 37% (IRR = 0.63, 95% CI: 0.21 to 1.93, P = 0.418) than WP participants. RR participants reported significantly fewer numbers of unprotected vaginal sex acts with their study partners (IRR = 0.58, 95% CI: 0.36 to 0.93, P = 0.024) and more consistent condom use (odds ratios = 2.30, 95% CI: 1.33 to 4.00, P = 0.003) over the entire follow-up period compared with WP participants. Conclusions: Project Renaissance demonstrated a significant effect for biological and behavioral endpoints. Findings draw attention to an HIV/HCV/STI prevention intervention strategy that can be scaled up for drug-involved couples in harm reduction programs, drug treatment, and criminal justice settings.
