Background and Aims: Hepatitis C (HCV) is a global public health concern, particularly in the prison setting where prevalence is substantially higher than in the general population. Direct‐acting antivirals have changed the treatment landscape, allowing for treatment scale‐up efforts potentially sufficient to achieve prevention of onward transmission (treatment‐as‐prevention). The Surveillance and Treatment of Prisoners with hepatitis C (SToP‐C) study was the first trial to examine the efficacy of HCV treatment‐as‐prevention in the prison setting. Social capital is a social resource which has been found to influence health outcomes. This qualitative study sought to understand the role of social capital within an HCV treatment‐as‐prevention trial in the prison setting. Design Semi‐structured in‐depth interviews were undertaken with participants recruited from the SToP‐C study following HCV treatment completion (with cure). Setting: Three male correctional centres in New South Wales, Australia (including two maximum‐security and one minimum‐security). Participants: Twenty‐three men in prison participated in semi‐structured interviews. Measurements Thematic analysis of transcripts was completed using a social capital framework, which enabled exploration of the ways in which bonding, bridging and linking social capital promoted or inhibited HCV treatment uptake within a treatment‐as‐prevention trial. Findings Social capital fostered HCV treatment uptake within an HCV treatment‐as‐prevention trial in the prison setting. Bonding social capital encouraged treatment uptake and alleviated concerns of side effects, bridging social capital supported prison‐wide treatment uptake, and linking social capital fostered trust in study personnel (including nurses and correctional officers), thereby enhancing treatment engagement. Conclusions: Social capital, including bonding, bridging and linking, can play an important role in hepatitis C treatment‐as‐prevention efforts within the male prison setting. [ABSTRACT FROM AUTHOR]

Reducing barriers to hepatitis C-related care requires us to strategically target opportunities at each health level in order to facilitate engagement among people who inject drugs (PWID). To this end, it is also critical that we understand more clearly what is meant and expected by health-care engagement among PWID.

Aims To estimate adherence and response to therapy for chronic hepatitis C virus (HCV) infection among people with a history of injecting drug use. A secondary aim was to identify predictors of HCV treatment response. Design Prospective cohort recruited between 2009 and 2012. Participants were treated with peg-interferon alfa-2a/ribavirin for 24 (genotypes 2/3, G2/3) or 48 weeks (genotype 1, G1). Setting Six opioid substitution treatment (OST) clinics, two community health centres and one Aboriginal community-controlled health organization providing drug treatment services in New South Wales, Australia. Participants Among 415 people with a history of injecting drug use and chronic HCV assessed by a nurse, 101 were assessed for treatment outcomes (21% female). Measurements Study outcomes were treatment adherence and sustained virological response (SVR, undetectable HCV RNA >24 weeks post-treatment). Findings Among 101 treated, 37% ( n = 37) had recently injected drugs (past 6 months) and 62% ( n = 63) were receiving OST. Adherence ≥ 80% was 86% ( n = 87). SVR was 74% (75 of 101), with no difference observed by sex (males: 76%, females: 67%, P = 0.662). In adjusted analysis, age < 35 (versus ≥ 45 years) [adjusted odds ratio (aOR) = 5.06, 95% confidence interval (CI) = 1.47, 17.40] and on-treatment adherence ≥ 80% independently predicted SVR (aOR = 19.41, 95% CI = 3.61, 104.26]. Recent injecting drug use at baseline was not associated with SVR. Conclusions People with a history of injecting drug use and chronic hepatitis C virus attending opioid substitution treatment and community health clinics can achieve adherence and responses to interferon-based therapy similar to other populations, despite injecting drugs at baseline. Younger age and adherence are predictive of improved response to hepatitis C virus therapy. [ABSTRACT FROM AUTHOR]
