Background and Aims: Hepatitis C virus (HCV) is highly prevalent within the prison setting. Although HCV testing and treatment are available within prisons, system barriers can impede progress along the HCV care cascade for those who are incarcerated. The PIVOT intervention used a 'one‐stop‐shop' model (i.e. point‐of‐care HCV RNA testing, Fibroscan‐based liver disease assessment and treatment) at a reception prison in New South Wales, Australia. This analysis sought to understand the role of point‐of‐care HCV RNA testing at intake in reducing barriers to the HCV care cascade within the male prison setting. Design and Setting: Qualitative analysis using semi‐structured interviews in a reception prison in Australia. Participants: Twenty‐four men enrolled in the PIVOT study; all participants had undergone HCV point‐of‐care testing in the intervention arm. Measurements: Høj's Integrated Framework informed this analysis. Findings: Participants widely expressed the view that point‐of‐care HCV RNA testing on entry was beneficial for care engagement. Point‐of‐care testing was perceived as timely (compared with standard pathology) and reduced opportunities for adjudication by correctional officers due to fewer clinic visits for testing and results. Adoption of routine opt‐out testing at prison intake was regarded as an important strategy for normalising HCV testing (and likely to increase pathways to treatment uptake) and fostered patient candidacy (i.e. self‐perceived eligibility to access care). Conclusion: Twenty‐four men in prison in New South Wales, Australia, who underwent opt‐out point‐of‐care HCV RNA testing on entry into prison, widely supported the programme as a means of overcoming barriers to HCV testing and treatment in the prison setting, as well as providing public health benefits through early detection of HCV infection among people entering into custody.

Since the advent of direct‐acting antiviral hepatitis C treatments, widespread enthusiasm about disease elimination has emerged. This article examines experiences of hepatitis C treatment and cure in this period. Mobilising Fraser and Seear's (Making disease, making citizens: The politics of hepatitis C, Ashgate, 2011) approach to hepatitis C as a 'gathering', we analyse cure not as a biomedical phenomenon but as a social and material event. To do so, we take a Science and Technology Studies‐inspired approach to analyse three complementary cases drawn from an Australian project on experiences of hepatitis C, treatment and cure. First, we analyse the ways a friendship between two women combines with adjustments to treatment access to produce a gathering that makes cure possible. Second, we analyse the forces that gather and distribute responsibility when a cure does not occur in a context shaped by oversimplified treatment logics. Third, we analyse a gathering of relations in which hepatitis C lingers, thereby limiting the cure's possible transformative effects. We argue that, even in an era defined by highly effective medicines, the hepatitis C cure is not necessarily straightforward, but an unpredictable gathering constituted by a fragile coalescing of social and material forces.

Background and aims: Mathematical modelling has demonstrated the theoretical feasibility of HCV treatment‐as‐prevention strategies in custodial settings, yet limited empirical data exists. The Australian 'Surveillance and Treatment of Prisoners with Hepatitis C' study is the world's first trial of hepatitis C virus (HCV) treatment‐as‐prevention in prison. This study aimed to analyse how expert stakeholders involved in the Australian HCV response assessed the acceptability of HCV treatment‐as‐prevention in prison using interview data from the SToP‐C qualitative substudy. Design and setting: Qualitative analysis using semi‐structured interviews in Australia. Participants: Nineteen key HCV experts. Measurements Drawing upon Sekhon's theoretical framework of acceptability, data were organized thematically under four component constructs of acceptability: affective attitude; ethicality; opportunity costs; and perceived effectiveness. Findings Most differences in participant assessments of acceptability were a matter of relative emphasis and prioritization rather than absolute polarity. Nonetheless, a small minority of participants was overtly critical of the approach. Arguing against the focus on treatment, they instead advocated for prevention‐as‐prevention, including the improvement and expansion of existing harm reduction measures. Conclusions: Qualitative analysis of expert stakeholder assessments of the acceptability of hepatitis C virus treatment‐as‐prevention in Australian prisons found no opposition to the universal rollout of direct‐acting anti‐virals, but most voiced concern regarding the lack of effective primary prevention in Australian prisons.

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]

Summary: Hepatitis C virus (HCV) infection is a major public health concern. Globally, 15% of those incarcerated are HCV‐antibody positive (anti‐HCV). Even where HCV treatment is available within prisons, treatment uptake has remained low. This qualitative study was conducted to understand the barriers and facilitators for the delivery of HCV treatment in prisons from the perspectives of prisoners. This is important to inform health messaging for HCV treatment within correctional institutions. Thirty‐two prisoners (including eight women) with a history of injecting drug use participated in this qualitative study. Participants were equally recruited across four correctional centres (n = 8 per site). Overall, 16 participants (50%) had chronic HCV at their most recent test, and two participants were awaiting test results at time of interview. Structural (eg proximity of health clinic) and patient‐level (routine and motivation) factors were viewed as facilitators of HCV treatment within the prison setting. Structural (eg risk of reinfection) and social (eg lack of confidentiality and lack of social support) factors were perceived as barriers to prison‐based HCV care and treatment. In conclusion, to increase HCV treatment uptake, prison‐based programmes should implement (or advocate for) patient‐centred treatment approaches that protect privacy, provide social support, and promote access to clean needles and substitution therapy to protect prisoners from reinfection.

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.

Injecting drug use remains the major risk factor for hepatitis C ( HCV) transmission. A minority of long-term injecting drug users remain seronegative and aviraemic, despite prolonged exposure to HCV - termed highly exposed seronegative subjects. Natural killer (NK) cells have been implicated in this apparent protection. A longitudinal nested, three group case-control series of subjects was selected from a prospective cohort of seronegative injecting drug users who became incident cases ( n = 11), remained seronegative ( n = 11) or reported transient high-risk behaviour and remained uninfected ( n = 11). The groups were matched by age, sex and initial risk behaviour characteristics. Stored peripheral blood mononuclear cells were assayed in multicolour flow cytometry to enumerate natural killer cell subpopulations and to assess functional activity using Toll-like receptor ligands before measurement of activation, cytokine production and natural cytotoxicity receptor expression. Principal components were derived to describe the detailed phenotypic characteristics of the major NK subpopulations (based on CD56 and CD16 co-expression), before logistic regression analysis to identify associations with exposed, seronegative individuals. The CD56dim CD16+ ( P = 0.05, OR 6.92) and CD56dim CD16− ( P = 0.05, OR 6.07) principal components differed between exposed, seronegative individuals and pre-infection samples of the other two groups. These included CD56dim CD16+ and CD56dim CD16− subsets with CD56dim CD16+ IFN- γ and TNF- α on unstimulated cells, and CD56dim CD16− CD69+, CD107a+, IFN- γ and TNF- α following TLR stimulation. The cytotoxic CD56dim NK subset thus distinguished highly exposed, seronegative subjects, suggesting NK cytotoxicity may contribute to protection from HCV acquisition. Further investigation of the determinants of this association and prospective assessment of protection against HCV infection are warranted. [ABSTRACT FROM AUTHOR]

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]

Aims To explore identity transformation among service users attending opiate substitution therapy ( OST) clinics following the introduction of hepatitis C ( HCV) care and treatment. Design An interview-based substudy of the Australian ETHOS (Enhancing Treatment for Hepatitis C in Opiate Substitution Settings) project. Setting Three OST clinics and one community health centre (operating a public OST) in New South Wales, Australia. Participants were interviewed at the recruitment sites. Participants The sample consisted of 57 OST service users concurrently living with HCV, 16 staff, including specialist HCV clinicians, and three peer-support workers, employed on the ETHOS project. Measurements Semi-structured interviews. Findings Service-user participants largely welcomed the introduction of HCV treatment as a practical, clinical intervention that also intimated a more comprehensive, holistic form of care. Negative stereotypes characteristic of OST settings-of limited, routinized clinical exchanges and minimal social-care interaction-were unsettled, opening up the possibility of new relations between staff and service users. The shift in the dynamic of the clinical encounter to address health in addition to dependence appeared to catalyse transformative possibilities not only for the therapeutic alliance but also for service-user understandings of self and identity. Conclusion Trial introduction of HCV care and treatment in selected Australian opiate substitution therapy (OST) clinics may have facilitated alternative, 'non-addict' identities to emerge from a clinical setting where the stigmatizing figure of 'the drug user' has traditionally prevailed.

Issues. In an effort to increase the number of people undergoing hepatitis C treatment, a range of initiatives are planned or underway to provide treatment in non-specialist services, such as opioid pharmacotherapy treatment (OPT) clinics. Approach. This commentary considers the implications of this new approach to treatment delivery, taking account of individual-level issues generally discussed in the literature, such as knowledge of treatment and concerns about side effects. In addition, because less visible organisational and structural factors would equally influence the successful implementation of hepatitis C treatment in OPT services, these are also explored. Key Findings. Provision of hepatitis C treatment in OPT services raises a broad range of pressing questions, from individual knowledge and concern about treatment, to workforce issues, such as discrimination, and tensions between the need for supportive care during hepatitis C treatment and the surveillant, regulatory nature of OPT clinic operations. Implications. A thorough critical examination of the structure and delivery of all services involved is necessary. Social research can play a unique role in this assessment because of its ability to generate detailed insights into lived experience and make use of social theories that allow previously invisible operations of power to become visible. Conclusion. The success of hepatitis C treatment in new sectors, such as OPT clinics, is not a given. Close attention needs to be paid to the context and culture in which OPT is delivered. In turn, this needs to be considered alongside the context and culture necessary for successful hepatitis C treatment delivery.[Treloar CJ, Fraser SM.
