Abstract Background Treatment uptake for hepatitis C virus (HCV) infection in people who inject drugs (PWID) and patients on opioid substitution therapy (OST) is still low despite treatment guidelines that advocate the use of direct-acting antivirals (DAAs) in all patients. Our aim in this review was to investigate treatment outcomes among PWID and patients on OST in comparison to control cohorts. Methods A search of Embase, Medline, PubMed, and Web of Science (from October 2010 to March 2018) was conducted to assess sustained virologic response (SVR), discontinuation rates, adherence, and HCV reinfection in PWID and patients on OST. Results We identified 11 primary articles and 12 conference abstracts comprising 1702 patients on OST, 538 PWID, and 19 723 patients who served as controls. Among patients on OST, the pooled SVR was 90% (95% confidence interval [CI], 87% to 93%) and pooled treatment discontinuation rate was 7% (95% CI, 4% to 11%). Similarly, the pooled SVR was 88% (95% CI, 80% to 93%) in PWID and the pooled treatment discontinuation rate was 9% (95% CI, 5% to 15%). There was no significant difference regarding pooled rates of SVR, adherence, and discontinuation between patients on OST and controls as well as between PWID and controls. HCV reinfection rates among patients on OST ranged from 0.0 to 12.5 per 100 person-years. Conclusions HCV treatment outcomes in PWID and patients on OST are similar to those in patients without a history of injecting drugs, supporting current guideline recommendations to treat HCV in these patient populations.

SUMMARYAlthough high hepatitis C virus (HCV) prevalence has been observed in people who inject drugs (PWID) for decades, research suggests incidence is falling. We examined whether PWIDs’ use of opioid substitution therapy (OST) and their needle-and-syringe sharing behaviour explained HCV incidence. We assessed HCV incidence in 235 PWID in Melbourne, Australia, and performed discrete-time survival with needle-sharing and OST status as independent variables. HCV infection, reinfection and combined infection/reinfection incidences were 7·6 [95% confidence interval (CI) 4·8–11·9], 12·4 (95% CI 9·1–17·0) and 9·7 (95% CI 7·4–12·6) per 100 person-years, respectively. Needle-sharing was significantly associated with higher incidence of naive HCV infection [hazard ratio (HR) 4·9, 95% CI 1·3–17·7] but not reinfection (HR 1·85, 95% CI 0·79–4·32); however, a cross-model test suggested this difference was sample specific. Past month use of OST had non-significant protective effects against naive HCV infection and reinfection. Our data confirm previous evidence of greatly reduced HCV incidence in PWID, but not the significant protective effect of OST on HCV incidence detected in recent studies. Our findings reinforce the need for greater access to HCV testing and prevention services to accelerate the decline in incidence, and HCV treatment, management and support to limit reinfection.
