Abstract
This study explores the role of perceived HCV stigma and social networks on HCV care among people who inject drugs (PWID) of both sexes, and solely among women who inject drugs (WWID). Data were from 269 HCV positive PWID, community-recruited through street-based outreach in Baltimore, MD. We defined HCV stigma based on participants' perceptions of treatment by others and their need to conceal their HCV status. Among WWID, HCV stigma was linked with decreased odds of undergoing liver disease staging (aOR = 0.33, 95% CI: 0.13,0.85) or to have attempted to get the HCV cure (aOR = 0.39, CI: 0.16,0.97), these associations were not evident in the overall sample with both sexes. Social network characteristics were significant correlates of HCV care in the overall sample, and these associations were stronger among WWID. WWID with more HCV positive social network members had higher odds of an HCV-related healthcare visit in the prior 12 months (aOR = 4.28, CI: 1.29,14.17) and to have undergone liver disease staging (aOR = 2.85, CI: 1.01,8.05). WWID with more social network members aware of the HCV cure were more likely to report an attempt at obtaining the HCV cure (aOR = 5.25, CI: 1.85,14.89). Our results suggest complexity in the role of social networks and stigma on HCV care.

Abstract
To achieve the World Health Organization's goal of eliminating hepatitis C (HCV) by 2030 requires enhanced HCV testing and treatment among people who use drugs (PWUD). Micro-elimination of HCV is a strategy to target HCV testing and treatment efforts to specific segments of the population. From February to December 2018 nurses initiated a "seek & treat" micro-elimination approach, increasing outreach and removing barriers to accessing HCV treatment in a clinic setting by testing and treating individuals, including PWUD, where they live. The aim of this study was to evaluate the proportion of clients with HCV antibodies and HCV RNA and the response to direct acting agent (DAA therapy) among people who live at or have social connections to local supportive housing sites through this nurse-led micro-elimination project in Victoria, Canada. A chart review of electronic medical records and case management documentation was used to collect relevant data of participants treated with DAA therapy, identified through specific housing site testing and outreach interventions. In total, 180 people were tested for HCV antibodies, 72 (40%) were antibody positive: 51 (28%) were RNA positive, 13 (7%) had spontaneously cleared and 8 (4%) had been previously treated. Of the 51 that were currently living with HCV, 43 people were started on treatment, 39 have achieved sustained virologic response (SVR). By providing treatment to clients in their homes and with their friends, clinicians have been able to treat clients, including those with limited contact with the health care system.

Reinfection following successful direct-acting antiviral therapy for HCV infection among people attending an inner-city community health centre in Victoria, Canada. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 96:103418. [PMID: 34538704 DOI: 10.1016/j.drugpo.2021.103418] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2021] [Revised: 07/08/2021] [Accepted: 08/06/2021] [Indexed: 01/03/2023]
Abstract
BACKGROUND Studies of HCV reinfection following direct-acting antiviral (DAA) therapy among PWID have been limited by short follow-up and small case numbers. This study evaluated the incidence of HCV reinfection following successful DAA therapy among people attending an inner-city community health centre in Victoria, Canada. METHODS In this observational study, participants treated with DAA therapy between November 2014 and December 31, 2019 were included. Retrospective chart review was performed to assess demographics, recent injecting drug use at treatment initiation (previous six months), opioid agonist treatment (OAT), and HIV. Endpoints included sustained virologic response (SVR), HCV reinfection, and mortality. RESULTS Of 482 participants initiating DAA treatment, 30% were female, 46% were receiving OAT, 49% had recent injection drug use, 15% had HIV/HCV coinfection, and 22% had cirrhosis. Treatment completion was 97% (468/482; 12 discontinued therapy, and 2 died during treatment). SVR was 87% (418/482). Outcomes among those who completed treatment but did not achieve SVR (n=53), included loss to follow-up (n=11), HCV RNA for SVR testing not completed (n=18), viral relapse (n=6), reinfection (n=5) and viral recurrence (n=5, unable to distinguish viral relapse from reinfection), and death (n=7). The rate of HCV reinfection was 3.6/100 person-years (95% confidence interval [CI] 2.4-5.5; 22 cases; 602 person-years follow-up). Factors associated with an increased risk of HCV reinfection included recent injection drug use (adjusted relative risk [aRR] 8.55, 95% CI 1.98-36.96) and HIV co-infection (aRR 2.35, 95% CI 1.01-5.44). Fifty-five people died (overdose, n=19) during (n=2) or following (n=53) therapy (7.4/100 person-years; 95% CI 5.6-9.6). CONCLUSION This study demonstrates ongoing reinfection among a marginalized population at an inner-city community health centre, with higher rates among those with HIV and recent injecting drug use. The rates of reinfection and mortality highlight the importance of integrating HCV care with strategies to address drug-related harms.

Abstract
OBJECTIVES People who inject drugs (PWID) are disproportionately impacted by hepatitis C virus (HCV). Despite the availability and efficacy of direct-acting antiviral (DAA) HCV therapies, treatment rates remain low among PWID. Among PWID, those who are young (under age 30) experience high rates of HCV and also face distinct barriers to care. The objective of this study is to identify facilitators and barriers to navigating various facets of the HCV cascade of care, including DAA treatment access, among young PWID. METHODS We draw on data from in-depth, semi-structured interviews conducted between May and November 2019 with a sample of 11 young, street-involved PWID who have lived experience of HCV and who live in Metro Vancouver, Canada. Informed by a social constructivist epistemology, data were thematically analyzed using an equity-oriented theoretical framework. RESULTS Our analysis yielded two key themes. First, participants described facilitators to HCV care access, including individual factors (e.g., desire to be cured, knowledge of side effects) and healthcare and socio-contextual factors (e.g., peer supports, supportive youth-specific services). Second, participants described a contrasting set of barriers to HCV care access, including concerns over treatment side effects and (in)eligibility, complex healthcare system navigation, substance use- and housing-related stigma, and clinician gatekeeping of DAAs. CONCLUSION Findings from this study underscore the need for HCV-related knowledge-building efforts among young PWID and clinicians. Also needed are structural policy interventions to facilitate access to DAAs, including anti-stigma efforts, access to safe housing, and the scale-up of low-barrier youth-specific services and decentralized HCV care.

Abstract
New therapies offer hope for a cure to millions of persons living with hepatitis C virus (HCV) infection. HCV elimination is a global goal that will be difficult to achieve using the traditional paradigms of diagnosis and care. The current standard has evolved toward universal HCV screening and treatment, to achieve elimination goals. There are several steps between HCV diagnosis and cure with major barriers along the way. Innovative models of care can address barriers to better serve hardly reached populations and scale national efforts in the United States and abroad. Herein, we highlight innovative models of HCV care that aid in our progress toward HCV elimination.

Abstract
Background and Objective While highly effective hepatitis C virus (HCV) therapies exist, gaps in the cascade of care remain. Disparities in the HCV cascade are prominent among underserved safety-net populations. We aim to evaluate the HCV cascade among an urban safety-net cohort of HCV patients. Methods We retrospectively evaluated adults with chronic HCV to determine rates of linkage to care (LTC), retention to care, and receiving HCV treatment from 2002 to 2018. Comparisons between groups utilized Chi-square testing; comparisons of median time to LTC and HCV treatment were evaluated with Student’s t-test and analysis of variance. Results Among 600 chronic HCV patients (60.7% male, 20.7% non-Hispanic white, 49.2% African American, 92.5% treatment naïve, 26.8% cirrhosis), successful LTC within one year of HCV diagnosis was 57.7%, among which, 91.6% were successfully retained into care. In those with successful LTC, 72.6% received HCV treatment, 91.8% completed treatment, and 89% achieved SVR12. Women with HCV experienced longer delays from LTC to HCV treatment (331 vs. 206 days in men, P < 0.05), as did African Americans (280 vs. 165 days in non-Hispanic whites, P < 0.05). Compared to the non-Hispanic whites, HCV treatment was lower in African Americans (70.4% vs. 74.4%, P < 0.05). Conclusion Women with HCV experienced significant delays along the HCV cascade, with median time of over 2 years from diagnosis to treatment. African Americans also experienced significant delays along the HCV cascade of care. However, sex and race/ethnicity were not found to be significant predictors of overall LTC or treatment.

Engagement in primary health care among marginalized people who use drugs in Ottawa, Canada. BMC Health Serv Res 2020; 20:837. [PMID: 32894114 PMCID: PMC7487534 DOI: 10.1186/s12913-020-05670-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Accepted: 08/19/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND There may be less primary health care engagement among people who use drugs (PWUD) than among the general population, even though the former have greater comorbidity and more frequent use of emergency department care. We investigated factors associated with primary care engagement among PWUD. METHODS The Participatory Research in Ottawa: Understanding Drugs (PROUD) cohort study meaningfully engaged and trained people with lived experience to recruit and survey marginalized PWUD between March-December 2013. We linked this survey data to provincial-level administrative databases held at ICES. We categorized engagement in primary care over the 2 years prior to survey completion as: not engaged (< 3 outpatient visits to the same family physician) versus engaged in care (3+ visits to the same family physician). We used multivariable logistic regression to determine factors associated with engagement in primary care. RESULTS Characteristics of 663 participants included a median age of 43 years, 76% men, and 67% living in the two lowest income quintile neighborhoods. Despite high comorbidity and a median of 4 (interquartile range 0-10) primary care visits in the year prior to survey completion, only 372 (56.1%) were engaged in primary care. Engagement was most strongly associated with the following factors: receiving provincial benefits, including disability payments (adjusted odds ratio [AOR] 4.14 (95% confidence interval [CI] 2.30 to 7.43)) or income assistance (AOR 3.69 (95% CI 2.00 to 6.81)), having ever taken methadone (AOR 3.82 (95% CI 2.28 to 6.41)), mental health comorbidity (AOR 3.43 (95% CI 2.19 to 5.38)), and having stable housing (AOR 2.09 (95% CI 1.29 to 3.38)). CONCLUSIONS Despite high comorbidity, engagement in primary care among PWUD was low. Our findings suggest that social care (housing, disability, and income support) and mental health care are associated with improved primary care continuity; integration of these care systems with primary care and opioid substitution therapy may lessen the significant morbidity and acute care use among PWUD.

Prevalence and high risk behaviours associated with HCV testing among people who inject drugs: a systematic review and Meta-analysis. SUBSTANCE ABUSE TREATMENT PREVENTION AND POLICY 2020; 15:64. [PMID: 32831107 PMCID: PMC7445934 DOI: 10.1186/s13011-020-00306-1] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/21/2020] [Accepted: 08/19/2020] [Indexed: 12/16/2022]
Abstract
BACKGROUND Hepatitis C diagnosis could be a gateway to behavioral change and subsequent decline in transmission among people who inject drugs (PWIDs). We assessed the association between the social determinants of PWID, their risk behaviors and hepatitis C testing. METHODS We searched for studies in English published before May 1, 2020, on PubMed, Scopus, Cochrane, and Web of Science to identify primary studies on the factors associated with hepatitis C virus (HCV) testing among PWID. After reviewing for study duplicates, the full-text of selected articles were assessed for eligibility using Population, Intervention, Comparator, Outcomes (PICO) criteria. i) population: individuals who report injecting drugs; ii) intervention: HCV testing in the past year; iii) comparator: PWIDs who did not have an HCV test; iv) outcome: HCV testing among PWIDs and v) study type: cross-sectional, cohort, and case-control studies. Two independent reviewers (author BA and AB) chose the references in a two-phased monitoring process. The authors gathered data from selected papers, including the surname of the first author, publication date, participant demographic data (age, sex, and level of education) and other characteristics like previous HCV testing, past treatment attempts, duration of injecting drug use and condomless sex. We used fixed and random-effects meta-analysis models to estimate the pooled prevalence, pooled odds ratio (OR), and 95% confidence intervals. The data were analyzed using Stata 12.0 software. RESULTS After a detailed assessment of over 12,000 articles, a total of 16 studies containing 38,952 participants met the eligibility criteria. Our findings showed a pooled prevalence rate of 61.01% (95% CI, 34.65-84.32%) for recent HCV testing among PWIDs. Being female (OR = 1.69, 95%CI = 1.13, 2.26), aged > 30 years, (OR = 2.61, 95%CI = 1.66-3.56) having past treatment attempt (OR = 2.24, 95%CI = 1.80-2.68), and reporting a previous test (OR = 2.03, 95%CI = 1.23-2.82). were significantly associated with having a recent HCV test.,,. Finding of present study was that unprotected sex had a negative association with HCV testing. Those PWIDs who had unprotected sex were 0.56 times less likely to have completed HCV testing during last year (OR = 0.56, 95%CI = 0.33-0.78). CONCLUSION Prevention programs that address age > 30 years, being female, past treatment attempt, previous testing of safe sexual practices, are strongly recommended to prioritize HCV risk reduction strategies.

Abstract
Objective
Although community-based models for treating hepatitis C virus (HCV) are widely recognised for reaching more people who require treatment, little is known about their organisational and operational elements. This study aimed to address this gap and develop a framework for designing, implementing and evaluating community-based models for treating HCV.
Methods
This study was a systematic review in which 17 databases were searched for published and unpublished studies. The final search of databases was performed in September 2017. A qualitative inductive thematic approach was used to extract and categorise organisational and operational elements of community-based models for treating HCV.
Results
Data analysis yielded 13 organisational and operational elements that were categorised into three domains: support for patients, support for healthcare providers and service delivery facilitation. In the support for patients domain, support was categorised into four elements: peer support, psychological assessment and support, social assessment and support and adherence support. In the support for healthcare providers domain, the elements included the provision of educational opportunities for HCV care providers, specialist mentoring, decision making support and rewarding and recognition for HCV care providers. Finally, the service delivery facilitation domain included seven elements that target service-level enablers for community-based HCV treatment, including essential infrastructure, policy implementation and collocation and collaboration with other related services.
Conclusion
This framework for understanding the components of models of community-based HCV treatment may be used as a guide for designing, implementing and evaluating models of care in support of HCV elimination. HCV care providers and patients need to be supported to improve their engagement with the provision of community-based treatment. In addition, evidence-based strategies to facilitate service delivery need to be included.

Community-based models for treating HCV are widely recognised as having the advantage of reaching more people who require treatment. These types of models aim to remove barriers related to accessibility and acceptability associated with tertiary centre-based HCV treatment.
What does this paper add?
Community-based models for treating HCV use various organisational and operational elements to improve the accessibility, effectiveness and acceptability of these services. The elements we identified target three main domains: support for patients with HCV, support for HCV care providers and service delivery facilitation. The importance of these organisational and operational elements designed to improve health and health services outcomes of community-based models for treating HCV is strongly influenced by context, and dependent on both the setting and target population.
What are the implications for practitioners?
Health policy makers and practitioners need to consider a patient’s psychosocial and economic status and provide support when needed. To successfully deliver HCV treatment in community settings, HCV care providers need to be trained and supported, and need to establish linkages, collaborations or colocations with other related services.

Abstract
Several community-based models for treating hepatitis C virus (HCV) infection have been implemented to improve treatment accessibility and health outcomes. However, there is a lack of knowledge regarding how well these models achieve the desired goals. We conducted a mixed-method systematic review of quantitative and qualitative evidence about clinical effectiveness, cost effectiveness and acceptability of community-based HCV treatment models. Seventeen databases were researched for published and unpublished studies. Methodological quality was assessed using The Joanna Briggs Institute Critical Appraisal tools. Quantitative findings were synthesized in narrative form and qualitative findings were synthesized using meta-synthesis. Forty-two quantitative and six qualitative studies were included. No relevant cost effectiveness studies were found. Five categories of community-based models were identified: telehealth, integration of HCV and addiction services, integration of HCV and HIV services, integration of HCV and primary care, and implementation by a home care and health care management company. The range of reported outcomes included; end of treatment response: 48.7% to 96%, serious side effects: 3.3% to 27.8%, sustained virological response: 22.3% to 95.5%, relapse: 2.2% to 16.7%, and treatment completion: 33.4% to 100%. Inconsistent measures of uptake and adherence were used; uptake ranged from 8.3% to 92%, and 68.4% to 100% of patients received ≥80% of prescribed doses. Patient reported experiences included trusted and supportive care providers, safe and trusted services, easily accessible care, and positive psychological and behavioural changes. The clinical effectiveness and acceptability reported from the included studies are similar to or better than reported outcomes from systematic reviews of studies in tertiary settings. Studies of the cost effectiveness of community-based models for treating HCV are needed.

Abstract
BACKGROUND A key to achieving the goal of hepatitis C virus (HCV) elimination is the provision of its treatment in community settings. This study aimed to identify the important organisational and operational elements of community-based models for treating HCV and their feasibility in the Australian context. METHODS A Delphi study was conducted with 33 experts from Australia. The questionnaire included 13 elements drawn from the literature. Participants rated each element on a five-point Likert scale for importance and feasibility and suggested additional elements. Consensus was identified when the sum of categories 1 and 2 or 4 and 5 of the five-point Likert scale reached greater than or equal to 70%. RESULTS Eight elements reached consensus in regard to importance including "Safe and enabling environment," "Training and support for healthcare providers," "Open referral policy," "Linkage with or providing outreach services," "Person-centred approach," "On-site screening and assessment," "Linkage or co-location with harm reduction services," and "Linkage or co-location with drug and alcohol services." At least 65% of participants agreed implementing elements of open referral policy, Training and support for healthcare providers, and Person-centred approach are usually or always/very feasible. For the other five elements, this was agreed to by a range of 15.2%-57.6% of participants. CONCLUSION Successful community-based models for treating HCV in Australia are dependent on the integration and coordination of care and the support provided for both patients and healthcare providers. Substantial work is required across policy and health service planning to integrate these highly rated elements into Australian primary health care.

Abstract
BACKGROUND Chronic hepatitis C virus (HCV) infection is common among people who inject drugs (PWID) and is associated with morbidity and premature death. Although HCV can be cured, treatment may be inaccessible. We studied HCV testing, status and treatment among marginalized people who use drugs in Ottawa, Canada, a setting with universal insurance coverage for physician services. METHODS We analyzed data from the Participatory Research in Ottawa: Understanding Drugs study, a cross-sectional, peer-administered survey of people who use drugs from 2012 to 2013. We linked responses to population-based health administrative databases and used multivariable Poisson regression to identify factors independently associated with self-reported HCV testing, self-reported positive HCV status, and database-determined engagement in HCV treatment. RESULTS Among 663 participants, 562 (84.8%) reported testing for HCV and 258 (45.9%) reported HCV-positive status. In multivariable analysis, HCV-positive status was associated with female gender (RR 1.27; 95%CI 1.04 to 1.55), advancing age (RR 1.03/year; 95%CI 1.02 to 1.04), receiving disability payments (RR 1.42; 95%CI 1.06 to 1.91), injecting drugs (RR 5.11; 95%CI 2.64 to 9.91), ever injecting with a used needle (RR 1.30; 95%CI 1.12 to 1.52), and ever having taken methadone (RR 1.26; 95%CI 1.05 to 1.52). Of HCV positive participants, 196 (76%) were engaged in primary care but only 23 (8.9%) had received HCV therapy. Conclusions/Importance: Although HCV testing and positive status rates are high among PWID in our study, few have received HCV treatment. Innovative initiatives to increase access to HCV treatment for PWID are urgently needed.

Abstract
BACKGROUND The worldwide economic, health, and social consequences of drug use disorders are devastating. Injection drug use is now a major factor contributing to hepatitis C virus (HCV) transmission globally, and it is an important public health concern. METHODS This article presents a narrative review of scientific evidence on public health strategies for HCV prevention among people who inject drugs (PWID) in Canada. RESULTS A combination of public health strategies including timely HCV detection and harm reduction (mostly needle and syringe programmes and opioid substitution therapy) have helped to reduce HCV transmission among PWID. The rising prevalence of pharmaceutical opioid and methamphetamine use and associated HCV risk in several Canadian settings has prompted further innovation in harm reduction, including supervised injection facilities and low-threshold opioid substitution therapies. Further significant decreases in HCV incidence and prevalence, and in corresponding disease burden, can only be accomplished by reducing transmission among high-risk persons and enhancing access to HCV treatment for those at the greatest risk of disease progression or viral transmission. Highly effective and tolerable direct-acting antiviral therapies have transformed the landscape for HCV-infected patients and are a valuable addition to the prevention toolkit. Curing HCV-infected persons, and thus eliminating new infections, is now a real possibility. CONCLUSIONS Prevention strategies have not yet ended HCV transmission, and sharing of injecting equipment among PWID continues to challenge the World Health Organization goal of eliminating HCV as a global public health threat by 2030. Future needs for research, intervention implementation, and uptake in Canada are discussed.

Abstract
BACKGROUND Among the estimated 340,000 people who inject drugs (PWID) in Ukraine, HCV prevalence is approximately 70%. As HCV treatment availability increases, an assessment of the HCV treatment cascade is needed to guide HCV prevention and treatment strategies. METHODS Opioid dependent PWID were interviewed and tested for HIV and HCV in five Ukrainian cities from January 2014 to March 2015. Logistic regression was used to examine the independent correlates of two cascade steps: a) anti-HCV positive status awareness; b) chronic HCV confirmation; and of c) annual HCV testing for PWID. RESULTS Among 1613 PWID, 1002 (62.1%) had anti-HCV positive test result, of which 568 (56.7%) were aware of it before the study and 346 (34.5%) reported previous confirmatory testing for chronic HCV. Independent correlates of being aware they had anti-HCV positivity included: current [AOR: 3.08; 95%CI: 2.16-4.40] or prior [AOR: 1.85; 95%CI: 1.27-2.68] opioid agonistic treatment (OAT) experience, relative to no prior OAT, living in Lviv [AOR: 0.50; 95%CI: 0.31-0.81] or Odesa [AOR: 2.73; 95%CI: 1.51-4.93] relative to Kyiv and being aware of having HIV [AOR: 4.10; 95%CI: 2.99-5.62]. Independent correlates of confirming HCV infection among those who were aware of their anti-HCV positive status included: current OAT [AOR: 2.00; 95%CI: 1.24-3.23], relative to prior OAT, the middle income category [AOR: 1.74, 95%CI: 1.15-2.63], relative to the lowest, and receiving ART [AOR: 4.54; 95%CI: 2.85-7.23]. Among 1613 PWID, 918 (56.9%) were either HCV negative or not aware of their HCV positive status, of which 198 (21.6%) reported recent anti-HCV test (during last 12 month). Recent anti-HCV test in this group was associated with current [AOR: 7.17; 95%CI: 4.63-11.13] or prior [AOR: 2.24; 95%CI: 1.32-3.81] OAT experience, relative to no prior OAT. CONCLUSION Encouraging PWID to participate in OAT may be an effective strategy to diagnose and link PWID who are HCV positive to care. Among HIV negative participants, regular HCV testing may be ensured by participation in OAT. More studies are needed to assess HCV treatment utilization among PWID in Ukraine and OAT as a possible way to retain them in treatment.

Implementing and scaling up HCV treatment services for people who inject drugs and other high risk groups in Ukraine: An evaluation of programmatic and treatment outcomes. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2017; 47:187-195.

Abstract
BACKGROUND HCV prevalence estimates among people who inject drugs (PWID) in Ukraine is high (60-90%), yet barriers to HCV treatment and care remain substantial including limited access to direct acting antiviral (DAA) medications. A feasibility scale-up project implemented HCV treatment in community-based settings to improve access to DAA treatment for key populations in this context. METHODS Using program-level data and verified medical records, we describe the development, implementation processes and outcomes for HCV treatment for PWID and other risks groups. Most participants (76%) received a combination of sofosbuvir, pegylated interferon, and ribavirin for 12 weeks. Treatment enrollment started in June 2015; the first two waves are reported. Data on demographics, HIV characteristics, HCV genotype and RNA levels, including sustained virologic response (SVR) were obtained from verified medical records. We used logistic regression to examine the independent correlates of achieving a SVR. RESULTS The project was implemented in 19 healthcare institutions from 16 regions of Ukraine, mainly within AIDS specialty centers. Our analytical sample included 1126 participants who were mostly men (73%) and the majority were HIV co-infected (79%). Treatment retention was 97.7%; the proportions of participants who achieved SVR for the overall sample and for those with complete data (N=1029) were 86.2% (95% CI 84.08-88.19%) and 94.3% (95% CI 92.8-95.7%) respectively. The analysis of data restricted to only those with SVR data available showed that PWID who were currently injecting had comparable SVR rates (89.2%, 95% CI 81.5-94.5%) to PWID not injecting (94.4%, 95% CI 92.4-96.1), PWID on methadone (94.4%, 95%CI 92.4-96.1), and 'other' risk groups (95.2%, 95% CI 91.3-97.7). Independent factors associated with achieving a SVR were female sex (AOR: 3.44, 95% CI 1.45-8.14), HCV genotype 3 (AOR: 4.57, 95% CI 1.97-10.59) compared to genotype 1. SVR rates in PWID actively injecting did not differ significantly from any other group. CONCLUSION Both patient-level and structural factors influence HCV treatment scale-up in Ukraine, but patient-level outcomes confirm high levels of achieving SVR in PWID, irrespective of injection and treatment status.

Abstract
BACKGROUND Although rates of sustained virologic response (SVR) after hepatitis C virus (HCV) treatment with direct-acting antivirals (DAAs) surpass 90% in trials and some more "real world" settings, some patients, such as those with substance use disorders, will be challenged to adhere to HCV care. METHODS To assess the feasibility of 2 strategies for financially incentivizing adherence to HCV care, patients with a substance use history prescribed 12 weeks of a sofosbuvir-containing regimen were randomized to either fixed or lottery-based monetary incentives for attending clinic appointments, pill count adherence >90%, and SVR achievement. Electronic medication monitoring provided an objective measure of DAA adherence. RESULTS Fifty-nine participants were randomized to the lottery (n = 31) or fixed-incentive (n = 28) arms. All 31 (100%) in the lottery arm and 24 of 28 (86%) in the fixed arm completed 12 weeks of therapy. By intent-to-treat, 93% in the lottery arm and 92% in the fixed arm achieved SVR (estimated difference: 0.5%; 95% confidence interval, -17.5 to 18.8). Overall, 92% of scheduled visits were attended without significant differences between arms. The mean adherence ratio (days with ≥1 bottle opening:monitored days) was 0.91 for lottery and 0.92 for fixed arms. CONCLUSIONS In this pilot, fixed- and lottery-based financial incentives were successfully implemented and accepted by patients with a substance use history. High levels of HCV therapy and care adherence, as well as rates of SVR, were observed. Financial incentives may be useful to support treatment adherence in patients with substance use disorders and should be tested in a larger, randomized, controlled trial.

Abstract
Background. Hepatitis C virus (HCV) coinfection occurs in 20-30% of Canadians living with HIV and is responsible for a heavy burden of morbidity and mortality. Purpose. To update national standards for management of HCV-HIV coinfected adults in the Canadian context with evolving evidence for and accessibility of effective and tolerable DAA therapies. The document addresses patient workup and treatment preparation, antiviral recommendations overall and in specific populations, and drug-drug interactions. Methods. A standing working group with HIV-HCV expertise was convened by The Canadian Institute of Health Research HIV Trials Network to review recently published HCV antiviral data and update Canadian HIV-HCV Coinfection Guidelines. Results. The gap in sustained virologic response between HCV monoinfection and HIV-HCV coinfection has been eliminated with newer HCV antiviral regimens. All coinfected individuals should be assessed for interferon-free, Direct Acting Antiviral HCV therapy. Regimens vary in content, duration, and success based largely on genotype. Reimbursement restrictions forcing the use of pegylated interferon is not acceptable if optimal patient care is to be provided. Discussion. Recommendations may not supersede individual clinical judgement. Treatment advances published since December 2015 are not considered in this document.

Abstract
In high income countries, the majority of new and existing hepatitis C virus (HCV) infections occur among people who inject drugs (PWID). In many low and middle income countries large HCV epidemics have also emerged among PWID populations. The burden of HCV-related liver disease among PWID is increasing, but treatment uptake remains extremely low. There are a number of barriers to care which should be considered and systematically addressed, but should not exclude PWID from HCV treatment. The rapid development of interferon-free direct-acting antiviral (DAA) therapy for HCV infection has brought considerable optimism to the HCV sector, with the realistic hope that therapeutic intervention will soon provide near optimal efficacy with well-tolerated, short duration, all oral regimens. Further, it has been clearly demonstrated that HCV treatment is safe and effective across a broad range of multidisciplinary healthcare settings. Given the burden of HCV-related disease among PWID, strategies to enhance HCV assessment and treatment in this group are urgently needed. These recommendations demonstrate that treatment among PWID is feasible and provide a framework for HCV assessment and care. Further research is needed to evaluate strategies to enhance testing, linkage to care, treatment, adherence, viral cure, and prevent HCV reinfection among PWID, particularly as new interferon-free DAA treatments for HCV infection become available.
