Life after hepatitis C cure in HIV-infected people who inject drugs and men who have sex with men treated with direct-acting antivirals in France: Health perceptions and experiences from qualitative and quantitative findings (ANRS CO13 HEPAVIH).

There remains a substantial gap in our understandings of the life experiences of patients following HCV cure among HIV-HCV-co-infected people who inject drugs (PWID) and men who have sex with men (MSM), two key populations targeted for HCV elimination. We described the experiences and perspectives of HIV-positive PWID and MSM, HCV-cured following treatment with direct-acting antivirals (DAA). We used an exploratory sequential mixed approach using both qualitative data (semi-structured interviews with 27 PWID and 20 MSM) and quantitative data (self-administered questionnaires with 89 PWID) via the prospective ANRS CO13 HEPAVIH cohort. PWID reported improvements in physical health-related quality of life (HRQL) and self-reported symptoms following treatment, but no significant change in mental HRQL. During interviews, several MSM, more recently diagnosed with HCV, expressed less concern regarding HCV than HIV infection and interpreted improvements in their overall well-being after HCV cure to be more related to a closer connection with healthcare providers than with viral elimination. By contrast, PWID, particularly those previously exposed to interferon-based treatments, described major improvements in their physical HRQL. Both MSM and PWID reported improvements in cognitive or psychological wellbeing, and a majority of them reported some degree of concern over potential HCV reinfection. To conclude, though health benefits of HCV cure concern both groups, HIV-infected PWID and MSM may have different representations and experiences following DAA treatment, related to their history with HCV. They are thus likely to benefit from holistic, post-treatment follow-up care that is responsive to their evolving health and social contexts.

High-intensity cannabis use and HIV clinical outcomes among HIV-positive people who use illicit drugs in Vancouver, Canada.

BACKGROUND: Reforms to the legal status of medical and non-medical cannabis are underway in many jurisdictions, including Canada, as are renewed efforts to scale-up HIV treatment-as-prevention (TasP) initiatives. It has been suggested that high-intensity cannabis use may be associated with sub-optimal HIV treatment outcomes. Thus, using data from a setting with a community-wide treatment-as-prevention (TasP) initiative coinciding with increasing access to medical cannabis, we sought to investigate the possible impact of high-intensity cannabis use on HIV clinical outcomes. METHODS: Data was derived from the ACCESS study, a prospective cohort of HIV-positive people who use illicit drugs (PWUD) in Vancouver, Canada. Cohort data was confidentially linked to comprehensive clinical profiles, including records of all antiretroviral therapy (ART) dispensations and longitudinal plasma HIV-1 RNA viral load (VL) monitoring. We used generalized estimating equations (GEEs) to estimate the longitudinal bivariable and multivariable relationships between at least daily cannabis use and two key clinical outcomes: overall engagement in ART care, and achieving a non-detectable VL among ART-exposed participants. RESULTS: Between December 2005 and June 2015, 874 HIV-positive PWUD (304 [35%] non-male) were included in this study. In total, 788 (90%) were engaged in HIV care at least once over the study period, of whom 670 (85%) achieved non-detectable VL at least once. In multivariable analyses, ≥ daily cannabis use did not predict lower odds of ART care (Adjusted Odds Ratio [AOR]: 1.02, 95% confidence interval [CI]: 0.77-1.36) or VL non-detectability among ART-exposed (AOR: 0.96, 95% CI: 0.75-1.21). Upon testing for potential interactions, ≥ daily cannabis use was found to be negatively associated with ART engagement during periods of binge alcohol use (p<0.05). CONCLUSION: With the exception of frequent cannabis use during periods of binge alcohol use, our results showed no statistically significant impact of daily cannabis use on the likelihood of ART care or VL non-detectability among ART-exposed HIV-positive PWUD. These findings are reassuring in light of the impending legalization of cannabis in Canada and ongoing efforts to expand TasP initiatives.
