Predictors of engagement in screening for a hepatitis C virus (HCV) treatment trial in a rural Appalachian community. J Viral Hepat 2024; 31:293-299.

Abstract
An HCV treatment trial was initiated in September 2019 to address the opioid/hepatitis C virus (HCV) syndemic in rural Kentucky. The focus of the current analysis is on participation in diagnostic screening for the trial. Initial eligibility (≥18 years of age, county resident) was established by phone followed by in-person HCV viremia testing. 900 rural residents met the inclusion criteria and comprised the analytic sample. Generalized linear models were specified to estimate the relative risk of non-attendance at the in-person visit determining HCV eligibility. Approximately one-quarter (22.1%) of scheduled participants were no-shows. People who inject drugs were no more likely than people not injecting drugs to be a no-show; however, participants ≤35 years of age were significantly less likely to attend. While the median time between phone screening and scheduled in-person screening was only 2 days, each additional day increased the odds of no-show by 3% (95% confidence interval: 2%-3%). Finally, unknown HCV status predicted no-show even after adjustment for age, gender, days between screenings and injection status. We found that drug injection did not predict no-show, further justifying expanded access to HCV treatment among people who inject drugs. Those 35 years and younger were more likely to no-show, suggesting that younger individuals may require targeted strategies for increasing testing and treatment uptake. Finally, streamlining the treatment cascade may also improve outcomes, as participants in the current study were more likely to attend if there were fewer days between phone screening and scheduled in-person screening.

Abstract
INTRODUCTION Australia has experienced sustained reductions in hepatitis C testing and treatment and may miss its 2030 elimination targets. Addressing gaps in community-based hepatitis C prescribing in priority settings that did not have, or did not prioritise, hepatitis C testing and treatment care pathways is critical. METHODS The Tasmanian Eliminate Hepatitis C Australia Outreach Project delivered a nurse-led outreach model of care servicing hepatitis C priority populations in the community through the Tasmanian Statewide Sexual Health Service, supported by the Eliminating Hepatitis C Australia partnership. Settings included alcohol and other drug services, needle and syringe programs and mental health services. The project provided clients with clinical care across the hepatitis C cascade of care, including testing, treatment, and post-treatment support and hepatitis C education for staff. RESULTS Between July 2020 and July 2022, a total of 43 sites were visited by one Clinical Nurse Consultant. There was a total of 695 interactions with clients across 219 days of service delivery by the Clinical Nurse Consultant. A total of 383 clients were tested for hepatitis C (antibody, RNA, or both). A total of 75 clients were diagnosed with hepatitis C RNA, of which 95% (71/75) commenced treatment, 83% (62/75) completed treatment and 52% (39/75) received a negative hepatitis C RNA test at least 12 weeks after treatment completion. CONCLUSIONS Providing outreach hepatitis C services in community-based services was effective in engaging people living with and at-risk of hepatitis C, in education, testing, and care. Nurse-led, person-centred care was critical to the success of the project. Our evaluation underscores the importance of employing a partnership approach when delivering hepatitis C models of care in community settings, and incorporating workforce education and capacity-building activities when working with non-specialist healthcare professionals.

A community-based strategy to eliminate hepatitis C among people who inject drugs in Vietnam. THE LANCET REGIONAL HEALTH. WESTERN PACIFIC 2023; 37:100801. [PMID: 37693880 PMCID: PMC10485672 DOI: 10.1016/j.lanwpc.2023.100801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 02/27/2023] [Accepted: 05/10/2023] [Indexed: 09/12/2023]
Abstract
Background Towards hepatitis C elimination among people who inject drugs (PWID), we assessed the effectiveness of a strategy consisting of a community-based respondent-driven sampling (RDS) as wide screening, a simplified and integrated hospital-based care, and prevention of reinfection supported by community-based organisations (CBO), in Hai Phong, Vietnam. Methods Adults who injected heroin were enrolled in a RDS survey implemented in two CBO premises. Rapid HIV and HCV tests were done on site, and blood was taken for HCV RNA testing. Those with detectable HCV RNA were referred with CBO support to three public hospitals for 12-week sofosbuvir/daclatasvir, plus ribavirin for patients with cirrhosis. Participants were followed-up 12 weeks post-treatment (SVR12) and 48 weeks after enrolment. The primary endpoint was the rate of undetectable HCV RNA participants at 48 weeks. Findings Among the 1444 RDS survey participants, 875 had hepatitis C. Their median age was 41 years (IQR 36-47), 96% were males, 36% were HIV-coinfected. Overall, 686 (78.4%) started sofosbuvir/daclatasvirs, and 629 of the 647 (97.2%) patients tested at SVR12 were cured. At week 48 (581/608) 95.6% had undetectable HCV RNA, representing 66.4% of all PWID identified with hepatitis C. The reinfection rate after SVR12 was 4/100 person-years (95% CI: 2-7). Interpretation Our strategy, involving CBO and addressing all steps from wide HCV screening to prevention of reinfection, stands as a promising approach to eliminate HCV among PWID in low and middle-income countries. Funding France ANRS|MIE (#ANRS12380). The RDS survey was implemented with grants from the NIDA (#R01DA041978) and ANRS|MIE (#ANRS12353).

Non-disclosure of drug injection practices as a barrier to HCV testing: results from the PrebupIV community-based research study. Harm Reduct J 2023; 20:98. [PMID: 37516889 PMCID: PMC10387207 DOI: 10.1186/s12954-023-00841-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Accepted: 07/22/2023] [Indexed: 07/31/2023] Open
Abstract
BACKGROUND Hepatitis C virus (HCV) infection prevalence is particularly high in people who inject drugs (PWID), a population that faces many barriers to HCV testing and care. A better understanding of the determinants of access to HCV testing is needed to improve their engagement in the HCV care cascade. We used data from a cross-sectional survey of people who inject drugs, mainly opioids, to identify factors associated with recent HCV testing. METHODS Self-reported data on HCV antibody testing were analyzed for 550 of the 557 PWID enrolled in PrebupIV, a French cross-sectional community-based survey which assessed PWID acceptability of injectable buprenorphine as a treatment. Factors associated with recent (i.e., in the previous six months) HCV antibody testing were identified performing multivariable logistic regression. RESULTS Among the study sample, 79% were men and 31% reported recent HCV antibody testing. Multivariable analysis found that PWID who did not disclose their injection practices to anyone (aOR [95% CI] 0.31 [0.12,0.82], p = 0.018), older PWID (aOR [95% CI] 0.97 [0.95,1.00], p = 0.030) and employed respondents (aOR [95% CI] 0.58 [0.37,0.92], p = 0.019) were all less likely to report recent HCV testing. No association was found between opioid agonist therapy and HCV testing. CONCLUSIONS Our findings suggest that non-disclosure of injection practices, employment and age were all barriers to HCV antibody testing. Preventing stigma around injection practices, developing the HCV testing offer in primary care and addiction care services, and training healthcare providers in HCV care management could improve HCV testing and therefore, the HCV care cascade in PWID.

Addict Sci Clin Pract 2023; 18:35. [PMID: 37245041 PMCID: PMC10221743 DOI: 10.1186/s13722-023-00384-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Accepted: 05/01/2023] [Indexed: 05/29/2023] Open
Abstract
BACKGROUND Hepatitis C virus (HCV) transmission is primarily driven by injection drug use, and acute HCV infection rates are increased in rural communities with substantial barriers to care. Treatment of HCV in persons who use drugs (PWUD) is cost effective, decreases high risk behaviors and HCV transmission, and achieves high rates of treatment completion and sustained viral response. Adapting HCV care delivery to utilize peer support specialists, telemedicine technology, and streamlined testing and treatment strategies can better reach rural populations living with HCV. METHODS This is an open label, two-arm, non-blinded, randomized controlled trial designed to test the superiority of peer-facilitated and streamlined telemedicine HCV care (peer tele-HCV) compared to enhanced usual care (EUC) among PWUD in rural Oregon. In the intervention arm, peers conduct HCV screening in the community, facilitate pretreatment evaluation and linkage to telemedicine hepatitis C treatment providers, and support participants in HCV medication adherence. For participants assigned to EUC, peers facilitate pretreatment evaluation and referral to community-based treatment providers. The primary outcome is sustained virologic response at 12 weeks post treatment (SVR12). Secondary outcomes include: (1) HCV treatment initiation, (2) HCV treatment completion, (3) engagement with harm reduction resources, (4) rates of substance use, and (5) engagement in addiction treatment resources. The primary and secondary outcomes are analyzed using intention-to-treat (ITT) comparisons between telemedicine and EUC. A qualitative analysis will assess patient, peer, and clinician experiences of peer-facilitated telemedicine hepatitis C treatment. DISCUSSION This study uses a novel peer-based telemedicine delivery model with streamlined testing protocols to improve access to HCV treatment in rural communities with high rates of injection drug use and ongoing disease transmission. We hypothesize that the peer tele-HCV model will increase treatment initiation, treatment completion, SVR12 rates, and engagement with harm reduction services compared to EUC. Trial registration This trial has been registered with ClinicalTrials.gov (clinicaltrials.gov NCT04798521).

Abstract
BACKGROUND This study examined associations between receipt of hepatitis C (HCV) treatment and retention in office-based opioid treatment (OBOT) care. METHODS We conducted a retrospective cohort study of HCV-infected patients who initiated OBOT treatment between December 2015 and March 2021 to characterize HCV treatment and assess associations with OBOT retention. HCV treatment was characterized as no treatment, early treatment (< 100 days since OBOT initiation) or late treatment (≥ 100 days). We evaluated associations between HCV treatment and cumulative days in OBOT. A secondary analysis using Cox Proportional Hazards regression was done to determine the rate of discharge over time when comparing those who did versus did not receive HCV treatment as a time-varying covariate. We also analyzed a subset of patients retained at least 100 days in OBOT care and evaluated whether HCV treatment during that period was associated with OBOT retention beyond 100 days. RESULTS Of 191 HCV-infected OBOT patients, 30% initiated HCV treatment, of whom 31% received early treatment and 69% received late treatment. Median cumulative duration in OBOT was greater among those who received HCV treatment (any: 398 days, early: 284 days and late: 430 days) when compared to those who did not receive treatment (90 days). Compared to no HCV treatment, there were 83% (95% CI: 33-152%, P < 0.001), 95% (95% CI: 28%-197%, p = 0.002 and 77% (95% CI: 25-153%, p = 0.002) more cumulative days in OBOT for any, early and late HCV treatment, respectively. HCV treatment was associated with a lower relative hazard for discharge/drop-out, although results did not meet statistical significance (aHR = 0.59;95% CI: 0.34-1.00; p = 0.052). Among the subset of 84 patients retained in OBOT at least 100 days, 18 received HCV treatment during that period. Compared to those who did not receive treatment within the first 100 days, those who received treatment had 57% (95% CI: -3%-152%, p = 0.065) more subsequent days in OBOT. CONCLUSIONS A minority of HCV-infected patients received HCV treatment after initiating OBOT treatment, but those who did had better retention. Further efforts are needed to facilitate rapid HCV treatment and evaluate whether early HCV treatment improves OBOT engagement.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 116:104044. [PMID: 37149914 DOI: 10.1016/j.drugpo.2023.104044] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Revised: 04/18/2023] [Accepted: 04/23/2023] [Indexed: 05/09/2023]
Abstract
BACKGROUND Improving HCV treatment uptake among people who inject drugs (PWID) is crucial to achieving the WHO elimination targets. The aims were to evaluate HCV treatment uptake and HCV RNA prevalence in a large cohort of PWID in Norway. METHODS Registry-based observational study where all users of the City of Oslo's low-threshold social and health services for PWID between 2010-2016 (n = 5330) were linked to HCV notifications (1990-2019) and dispensions of HCV treatment, opioid agonist treatment (OAT) and benzodiazepines (2004-2019). Cases were weighted to account for spontaneous HCV clearance. Treatment rates were calculated using person-time of observation, and factors associated with treatment uptake were analysed using logistic regression. HCV RNA prevalence was estimated among individuals alive by the end of 2019. RESULTS Among 2436 participants with chronic HCV infection (mean age 46.8 years, 30.7% female, 73.3% OAT), 1118 (45.9%) had received HCV treatment between 2010-2019 (88.7% DAA-based). Treatment rates increased from 1.4/100 PY (95% CI 1.1-1.8) in the pre-DAA period (2010-2013) to 3.5/100 PY (95% CI 3.0-4.0) in the early DAA period (2014-2016; fibrosis restrictions) and 18.4/100 PY (95% CI 17.2-19.7) in the late DAA period (2017-2019; no restrictions). Treatment rates for 2018 and 2019 exceeded a previously modelled elimination threshold of 50/1000 PWID. Treatment uptake was less likely among women (aOR 0.74; 95% CI 0.62-0.89) and those aged 40-49 years (aOR 0.74; 95% CI 0.56-0.97), and more likely among participants with current OAT (aOR 1.21; 95% CI 1.01-1.45). The estimated HCV RNA prevalence by the end of 2019 was 23.6% (95% CI 22.3-24.9). CONCLUSION Although HCV treatment uptake among PWID increased, strategies to improve treatment among women and individuals not engaged in OAT should be addressed.

Usefulness of dried blood spot samples for monitoring hepatitis C treatment outcome and reinfection among people who inject drugs in a test-and-treat program. J Med Virol 2023; 95:e28544. [PMID: 36727653 DOI: 10.1002/jmv.28544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 01/20/2023] [Accepted: 01/30/2023] [Indexed: 02/03/2023]
Abstract
Dried blood spots (DBS) are a reliable tool to diagnose viremic hepatitis C virus (HCV) infection. We evaluated the clinical performance of a DBS-based molecular assay for the assessment of cure and reinfection after on-site treatment at a harm reduction center (HRC). Genotyping from DBS samples was also assessed to discriminate reinfection from treatment failure. People who inject drugs (PWID) from an ongoing test-and-treat pilot at the largest HRC in Barcelona were included in the study. HCV-RNA detection from DBS collected after treatment (with follow-up at 12, 36, and 60 weeks) was compared with a molecular point-of-care test using finger-stick blood (GeneXpert). Baseline and follow-up DBS samples were genotyped by NS5B sequencing or commercial real-time PCR. Among treated patients, 193 follow-up DBS samples were tested. The DBS-based assay showed 100% specificity (129/129), and sensitivity ranged from 84.4% to 96.1% according to different viral load cut-offs (from detectable to 3000 IU/mL). Sensitivity as test of cure (follow-up 12) ranged from 85.1% to 97.4%. Among the 64 patients with recurrent viremia, 10.9% had low viral loads (≤1000 IU/mL); HCV genotyping allowed us to classify 73.5% of viremic cases either as reinfection or as treatment failure. DBS samples are useful to assess cure and differentiate reinfection from relapse after HCV antiviral treatment in the real world, facilitating decentralization of treatment and posttreatment follow-up in PWID. However, a fraction of patients presented with low viral loads, limiting viremia detection and genotyping in DBS and, therefore, repeat testing is recommended.

Abstract
ABSTRACT The rising prevalence of opioid use disorder and injection drug use has resulted in an increasing incidence of chronic hepatitis C virus (HCV) infection. Although older adults historically have represented the bulk of HCV infections in the United States, demographics have shifted and most new infections are presenting in younger patients. As a result, screening guidelines for HCV have evolved, moving toward a near-universal screening paradigm. Rates of screening and linkage to care remain low, attributed to the fact that underserved populations are disproportionately affected and often have limited access to specialty care. Collaborative models to treat HCV using primary care providers have been proposed to facilitate linkage to care and reduce transmission.

Abstract
Hepatitis C virus (HCV) treatment in people who inject drugs (PWID) is delivered within settings frequented by PWID, such as needle and syringe programs (NSP). The optimal direct-acting antiviral (DAA) dispensing regimen among NSP clients is unknown. This study compared cures (Sustained virologic response 12 weeks post-treatment, [SVR12 ]) across three dispensing schedules to establish non-inferiority of fortnightly dispensing versus directly observed therapy. The ADVANCE HCV study was a randomized, unblinded trial, recruiting PWID attending NSP in Tayside, Scotland, between January 2018 and November 2019. HCV-positive participants were randomized to receive DAAs via directly observed therapy, fortnightly provision or fortnightly provision with psychological intervention. A modified intention to treat analysis was used to identify differences in cures between the three treatment regimes. The study was registered with clinicaltrials.gov; NCT03236506. A total of 110 participants completed the study. 33 participants received directly observed therapy, with 90.91% SVR12 ; 37 received fortnightly provision, with 86.49% SVR12 and 40 received fortnightly provision and psychological intervention at treatment initiation, with 92.50% SVR12 . Analysis showed no significant difference in SVR12 (p = 0.67). This study did not demonstrate a statistically significant difference in cure rate between groups. This provides evidence of the non-inferiority of fortnightly dispensing of direct-acting antivirals (DAAs) compared to directly observed therapy among PWID. It suggests that tight control of adherence through directly observed therapy dispensing of DAAs among this population offers no therapeutic advantage. Therefore, less restrictive dispensing patterns can be used, tailored to patient convenience.

Abstract
Poor access to care has made western North Carolina vulnerable to an outbreak of hepatitis C viral infection (HCV), particularly among persons who inject drugs (PWID). As substance use disorder (SUD) treatment providers could potentially improve linkage to HCV testing and treatment, we sought to understand SUD providers, clinic and client characteristics; referral patterns; HCV knowledge; willingness to participate in additional trainings; and local linkage-to-care pathways for treatment of substance use and HCV. Online survey data were collected from 78 SUD providers serving PWID in eight western rural North Carolina counties. Providers' attitudes toward working with HCV+ clients were very positive. One-third of providers reported a low fund of knowledge regarding HCV, HCV treatment, and financial assistance opportunities. Non-prescribing providers rarely initiated discussions about HCV testing/treatment, but were receptive to training. Respondents indicated that HCV testing and treatment were best delivered at local health departments or primary care clinics but were open to other venues where PWID access care. The vast majority of prescribing and non-prescribing providers expressed interest in obtaining training in HCV treatments, how to obtain HCV medications and topics on advanced liver disease. Data from prescribing and non-prescribing SUD providers suggest opportunities to develop or expand integrated care models for HCV testing/treatment in PWID in rural Appalachian North Carolina.

Abstract
BACKGROUND There has been a paradigm shift in the treatment of Hepatitis C (HCV) from the interferon-era to direct-acting antiviral (DAA) drugs. Cure of HCV for the key risk group, those with a history of injecting drug use, may provide a range of benefits to an individual's quality of life that can be additional to that of a clinical cure. The interferon-era provided evidence that cure of HCV can be a turning point for those who use drugs, supporting a recovery journey. There remains a question if DAAs can provide the same opportunity. METHODS We employed a scoping review methodology to consider the additional non-clinical benefits that HCV cure may provide. We used the theoretical construct of recovery capital to consider how these benefits may support a recovery journey in the DAA-era. RESULTS Our search provided 2095 articles, from which 35 were included in the analysis. We developed a thematic synthesis of the non-clinical outcomes identified based on the four over-arching themes of recovery capital: physical, cultural, social and human capital. Our review suggests that identity change is a constituent part of each of the recovery capital domains in relation to HCV treatment. CONCLUSION We identified Social Identity Model Of Recovery (SIMOR) as a mechanism through which DAAs may provide non-clinical outcomes to increase recovery capital domains. Further research is required to develop an understanding of the impact a cure of HCV with DAAs may have on identity, overall health and wellbeing and social inclusion to support recovery journeys.

Abstract
INTRODUCTION People who inject drugs (PWID) have complex health needs and often experience poor health outcomes. For PWID, intersectional experiences of stigma and other social vulnerabilities may influence their experiences navigating medical care. We conducted a targeted subanalysis of qualitative interview data collected to inform development of a community-pharmacist care model for hepatitis C (HCV) among PWID to explore intersectional influences on health care-seeking experiences. METHODS The study recruited participants from community organizations in Seattle, Washington, and participants were eligible if they reported injection drug use within 3 months and having HCV. Study staff conducted semi-structured interviews and two independent coders transcribed and initially analyzed them using a Rapid Assessment Process, guided by the Consolidated Framework for Implementation Research. Themes emerged regarding intersections of stigma and social vulnerabilities; thus, we conducted a targeted subanalysis guided by Fundamental Cause Theory and Earnshaw et al.'s Stigma Framework. RESULTS Forty participants (65% male; 47% non-white) reported multiple social vulnerabilities (e.g., regarding unstable housing and food insecurity). Qualitative analysis identified that receiving health care in the context of social vulnerability is challenging and burdensome (Theme 1); health care interactions are fraught with stigma stemming from intersectional vulnerabilities (Theme 2); and the belief that abstaining from drug use is needed to prove worthiness for care (Theme 3). PWID described experiencing multiple social vulnerabilities (e.g., unmet basic needs) that made seeking health care burdensome. Interactions with health care teams further reinforced participants' feelings of shame about their drug use, which influenced how participants expressed their care preferences and felt heard by providers. And as PWID navigated health care, they felt that their status as an active drug user was used to control and sometimes coerce their access to services, discouraging PWID from seeking needed care. CONCLUSIONS Stigma and social vulnerabilities play a pervasive and intersecting role in the health care-seeking experiences of PWID and negatively impact their ability to navigate and receive care they need. Evidence-based stigma reduction interventions at multiple levels, coupled with person-centered approaches to care delivery, may help to mitigate negative impacts.

Abstract
The elimination of viral hepatitis in target populations is crucial in reaching WHO viral hepatitis elimination goals. Several barriers for the treatment of viral hepatitis in people with addictive disorders have been identified, yet nationwide data on hepatitis healthcare utilization (HCU) in these patients are limited. We investigated whether a history of addictive disorder is associated with suboptimal hepatitis HCU, indicating failure to receive diagnostic care or treatment. We identified all newly referred viral hepatitis patients in the Netherlands between 2014 and 2019 by query of the Dutch national hospital claims database. Each patient’s first year of HBV or HCV care activities was collected and clustered in two categories, ‘optimal’ or ‘suboptimal’ hepatitis HCU. Optimal HCU includes antiviral therapy. We tested the association between addiction history and HCU, adjusted for sex, age, migrant status, and comorbidity. In secondary analyses, we explored additional factors affecting hepatitis HCU. We included 10,513 incident HBV and HCV patients, with 13% having an addiction history. Only 47% of all patients achieved optimal hepatitis HCU. Addiction history was associated with less suboptimal HCU (adjusted OR = 0.73, 95% CI = 0.64–0.82). Migration background was associated with suboptimal HCU (OR = 1.62, 95% CI = 1.50–1.76). This study shows that addiction history is associated with higher viral hepatitis HCU; thus, this population performs better compared to non-addicted patients. However, less than 50% of all patients received optimal hepatitis care. This study highlights the need to improve hepatitis HCU in all patients, with a focus on migrant populations. Linkage to care in the addicted patients is not studied here and may be a remaining obstacle to be studied and improved to reach WHO viral hepatitis elimination goals.

Abstract
BACKGROUND AND AIMS People who inject drugs (PWID) and other marginalized populations with high hepatitis C virus (HCV) infection rates represent a unique challenge for treatment initiation due to health, administrative and social barriers. We analysed the HCV cascade of care (CoC) in some vulnerable subpopulations in Madrid, Spain, when using a mobile point-of-care (PoC). METHODS From 2019 to 2021, a mobile unit was used to screen active HCV using a linkage-to-care and two-step PoC-based strategy. Viremic participants were grouped into four subgroups: PWID, homeless individuals and people with a mental health disorder (MHD) and alcohol use disorder (AUD). Logistic regression, and Cox and Aalen's additive models were used to analyse associated factors and differences between groups. RESULTS A prospectively recruited cohort of 214 HCV-infected individuals (73 PWID, 141 homeless, 57 with a MHD and 91 with AUD) participated in the study. The overall HCV CoC analysis found that 178 (83.1%) attended a hospital, 164 (76.6%) initiated direct-acting antiviral therapy and 141 (65.8%) completed therapy, of which 99 (95.2%) achieved sustained virological response (SVR). PWID were significantly less likely to initiate treatment, whereas individuals with AUD waited longer before starting the treatment. Both people with AUD and PWID were significantly less likely to complete HCV treatment. CONCLUSIONS Overall, SVR was achieved in the majority of the participants treated. However, PWID need better linkage to care and treatment, whereas PWID and AUD need more support for treatment completion.

Client resistance to hepatitis C treatment initiation in opioid agonist treatment clinics in Sydney, Australia: A qualitative study. Drug Alcohol Rev 2021; 41:706-714.

Abstract
INTRODUCTION Opioid agonist treatment (OAT) clinics play a key role in achieving elimination of hepatitis C virus (HCV) globally. Previous research has identified barriers to HCV treatment uptake in OAT clinics; however, most studies were conducted prior to the introduction of direct-acting antiviral treatments (DAA). It remains unclear whether progress has been made in responding to barriers and what challenges persist in this setting. METHODS Semi-structured in-depth interviews were conducted with staff (n = 20) and clients (n = 15) in two OAT clinics in Sydney, Australia. Interviews were transcribed verbatim and analysed using constant comparative methods. RESULTS Despite progress in integrating hepatitis C care in the clinics, competing priorities, concerns about side-effects, distrust of staff, health problems and difficulties accessing testing and medication persisted as key reasons why clients had not initiated treatment. Most clients preferred to postpone treatment and focus on other priorities and some highlighted lack of medical evidence for urgent treatment. Pressure on services to achieve elimination targets within set time frames was a primary driver of repeated offers of treatment by staff and the framing of clients' preferences for postponing treatment, as a barrier. DISCUSSION AND CONCLUSION Current timelines for HCV elimination targets may have galvanised services into action but may have also created tensions at the coalface due to disparities between staff and clients' priorities. The involvement of peer workers and mechanisms to ensure continued follow up with clients about DAA treatments is required. Public health timelines for HCV elimination need to be informed by affected communities' priorities.

Abstract
BACKGROUND: Patients with substance use disorders (SUD) and chronic hepatitis C virus infection (HCV) have limited access to direct-acting antivirals (DAAs) due to multilevel issues related to providers (eg, concern about reinfection); patients (eg, refusal); payers (eg, prior authorization); and health system structure, although clinical guidelines recommend timely DAA treatment for patients with SUD and HCV. Effects of DAAs on real-world health care utilization and costs among these patients is unknown. OBJECTIVE: To compare changes in medical service utilization and costs related to liver, SUD, and all-cause morbidity in patients with SUD and HCV treated with DAAs (DAA group) vs not treated with DAAs (non-DAA group). METHODS: We conducted a retrospective cohort study using MarketScan Commercial and Medicare Supplemental Claims databases (2012-2018) for newly diagnosed HCV treatment-naive adults with SUD. We used difference-in-differences analyses, stratified by cirrhosis status, to determine the adjusted ratio of rate ratio (RoRR) to assess the difference in the relative changes from the pre- to posttreatment periods between the 2 groups. RESULTS: 6,266 patients with SUD and HCV were identified. Of these patients who also had cirrhosis (n = 607), 49% (n = 298) initiated DAA therapy for HCV, whereas of those without cirrhosis (n = 5,659), 22% (n = 1,219) initiated DAAs. For patients with cirrhosis (n = 607), the liver-related costs decreased by $6,213 (95% CI = -$8,571, -$3,856) for the DAA group and $1,585 (95% CI = -$4,659, $1,490) for the non-DAA group. The relative decreases in the rate of liver-related costs were larger for the DAA group than for the non-DAA group, and the relative changes between groups were significantly different (RoRR = 0.37, 95% CI = 0.19-0.73). There was no difference in the relative changes after DAAs in the rate of SUD-related visits/costs or all-cause costs between the 2 groups. For patients without cirrhosis (n = 5,659), a similar association was observed. Besides, the relative decreases in the rate of SUD-related emergency department (ED) visits (RoRR = 0.54, 95% CI = 0.38-0.77); SUD-related long-term care visits (RoRR = 0.30, 95% CI = 0.13-0.73); all-cause ED visits (RoRR = 0.75, 95% CI = 0.64-0.88); and all-cause long term-care visits (RoRR = 0.36, 95% CI = 0.18-0.72) were larger in the DAA group than in the non-DAA group. CONCLUSIONS: DAAs are associated with a significant decrease in the rate of SUD-related ED visits and liver-related costs without increasing the rate of all-cause costs among patients with SUD and HCV, suggesting that the benefits of DAAs extended beyond liver-related outcomes, especially in this disadvantaged population. DISCLOSURES: Research reported in this publication was supported in part by the National Institute on Drug Abuse of the National Institutes of Health (K01DA045618). The funder did not have a role in the design, the execution, the analyses, the interpretation of the data, or the decision to submit the results of this study.

Abstract
BACKGROUND Reaching World Health Organization hepatitis C (HCV) elimination targets requires diagnosis and treatment of people who use drugs (PWUD) with direct acting antivirals (DAAs). PWUD experience challenges engaging in HCV treatment, including needing multiple provider and laboratory appointments. Women, minoritized racial communities, and homeless individuals are less likely to complete treatment. METHODS We implemented a streamlined opt-out HCV screening and linkage-to-care program in two healthcare for the homeless clinics and a medically supported withdrawal center. Front-line staff initiated a single-order reflex laboratory bundle combining screening, confirmation, and pre-treatment laboratory evaluation from a single blood draw. Multinomial logistic regression models identified characteristics influencing movement through each stage of the HCV treatment cascade. Multiple logistic regression models identified patient characteristics associated with HCV care cascade progression and Cox proportional hazards models assessed time to initiation of DAAs. RESULTS Of 11,035 clients engaged in services between May 2017 and March 2020, 3,607 (32.7%) were screened. Of those screened, 1,020 (28.3%) were HCV PCR positive. Of those with detectable RNA, 712 (69.8%) initiated treatment and 670 (94.1%) completed treatment. Of those initiating treatment, 407 (57.2%) achieved SVR12. There were eight treatment failures and six reinfections. In the unadjusted model, the bundle intervention was associated with increased care cascade progression, and in the survival analysis, decreased time to initiation; these differences were attenuated in the adjusted model. Women were less likely to complete treatment and SVR12 labs than men. Homelessness increased likelihood of screening and diagnosis but was negatively associated with completing SVR12 labs. Presence of opioid and stimulant use disorder diagnoses predicted increased care cascade progression. CONCLUSIONS The laboratory bundle and referral pathways improved treatment initiation, time to initiation, and movement across the cascade. Despite overall population improvements, women and homeless individuals experienced important gaps across the HCV care cascade.

Abstract
Hepatitis C virus (HCV) prevalence is high among people living with HIV co-infected with HCV, people who inject drugs, men who have sex with men and inmates in correctional settings. The barriers to eliminate HCV among these key populations include diagnosis challenges, lack of awareness, discrimination and stigmatization. In addition, scaling up of HCV treatment has been a challenge in Asia–Pacific with the lack of national policies, targets and unavailability of appropriate direct-acting antivirals regimens. In order to achieve HCV micro elimination within these high-risk populations, novel strategies to improve the cascade of care from diagnosis to treatment with direct-acting antivirals, complemented by behavioral change interventions, harm reduction services for people who inject drugs, civil society led advocacy and policies from the government, will be necessary.

Abstract
INTRODUCTION Direct-acting antivirals (DAAs) are an opportunity for hepatitis C virus (HCV) elimination. Strategies are needed to diagnose new patients and to attract those diagnosed without evaluation. Patients with other chronic viral diseases who receive satisfactory treatment promote referral of other patients for evaluation. Our aim was to evaluate whether patients who have been treated with DAAs would recommend follow-up and treatment to other patients as well as the characteristics that influence this decision. PATIENTS AND METHODS Two-hundred and 2HCV-infected patients treated with DAAs were included. Patients were asked about whether they knew other infected people and their willingness to share their experience. A general satisfaction survey and a specific HCV satisfaction survey were carried out. Demographic, socioeconomic and HCV infection variables were recorded. RESULTS Despite the fact that 54.4% of the patients reported knowing others infected, 34.2% would not fully agree to share their experience. The analysis of general and specific satisfaction showed that patients who shared their experience mentioned a perception of greater care from the specialist (4.7±0.4 vs. 4.3±0.6, P=.001) and had more information on treatment expectations (4.6±0.5 vs. 4.0±0.7, P=.001) and social support (4.5±0.7 vs. 4.0±0.8, P=.001). CONCLUSIONS The perception by treated patients of general satisfaction with the healthcare process and information about benefits influences the degree of recommendation to other infected people. Knowledge about treatment and perception of improvement in health of treated patients should be enhanced as it can contribute to increasing referrals to specialized consultation.

Telemedicine and decentralized hepatitis C treatment as a strategy to enhance retention in care among people attending drug treatment centres. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 94:103235.

Abstract
BACKGROUND People attending drug treatment centres have a high burden of hepatitis C virus (HCV) and face barriers to diagnosis and treatment. Dried blood spot (DBS) testing has been proposed to simplify diagnosis, but many patients remain untreated. In this retrospective study, we evaluated the reasons for non-retention in care in an intervention using on-site DBS testing and the effect of telemedicine and decentralized care compared to standard of care among people attending drug treatment centres who were lost to follow-up. METHODS In a first phase, retention in care, adherence to treatment, and predictive factors in the DBS testing program of patients in drug treatment centres were analyzed and compared to a cohort of patients treated at the hospital outpatient clinic. Subsequently, in a second phase we evaluated in patients lost to follow-up from drug treatment centres the efficacy of one-step testing and telemedicine linked to a decentralized dispensation of HCV treatment or standard of care. RESULTS Among 512 patients attending drug treatment centres, 467 (91.2%) agreed to be tested and 53.4% (237 patients/444 valid tests) tested positive (46 ± 9 years, 87.3% male) for HCV antibodies. After excluding patients negative for RNA or under surveillance, 178 patients were scheduled to meet with a specialist. Overall, 44 patients did not attend and 25 did not complete the pre-treatment evaluation. The only factor associated with retention in care was patient's knowledge of HCV infection. Treated patients attending drug treatment centres (n = 68) compared to the hospital outpatient clinic cohort (n = 135) had lower rates of treatment adherence. Among the patients who attended drug treatment centres that were lost to follow-up (n = 69), the proportion of patients who completed the program was significantly higher among those assisted by telemedicine than by standard of care (62.5% vs. 24.3%, p = 0.002). CONCLUSION Although there was a high participation rate in a DBS testing program in drug treatment centres, non-retention in care is a challenge. Importantly, telemedicine linked to a decentralized dispensation of HCV treatment re-engages patients and may be effective for HCV microelimination.

Abstract
Hepatitis C virus (HCV) infection remains an important cause of morbidity and mortality throughout the world, leading to serious health problems among those who are chronically infected. Since 1992, the Centers for Disease Control and Prevention has been collecting data on the incidence of HCV infection in the United States. In 2018, more than 50 000 individuals were estimated to have acute HCV infection.The most recently reported data on the prevalence of infection indicate that approximately 2.4 million people are living with hepatitis C in the United States. Transmission of HCV occurs predominantly through sharing contaminated equipment for injecting drugs.Two major events have had a significant impact on the incidence and prevalence of hepatitis C in the past few decades: the US opioid crisis and the discovery of curative treatments for HCV infection. To better understand the impact of these events, we examine reported trends in the incidence and prevalence of infection.

Abstract
Despite disproportionately high rates of Hepatitis C (HCV) among people who inject drugs (PWID) in low- and middle-income countries (LMICs), understanding of HCV-related knowledge, attitudes and perceived risk behaviours among this population remains limited. We aimed to elucidate knowledge, attitudes and experiences that could minimise transmission risk and maximise HCV treatment engagement among PWID in Kenya following the integration of HCV screening and education with needle and syringe programmes in drop-in-centres (DICs). We recruited 40 PWID with chronic HCV attending DICs in Nairobi and Coastal Kenya. Semi-structured interviews revealed a general understanding of HCV and awareness of HCV risk behaviours among participants; however, many felt limited control over their transmission risk due to factors such as 'local doctors', or individuals who perform a high volume of high-risk injections. Financial barriers, distance to clinic, poor health status and HCV-related stigma were all noted as barriers to HCV treatment. In conclusion, basic knowledge of and motivation for HCV treatment among PWID accessing DICs in Kenya was high; however, structural barriers and stigma complicate access to care. Local education programmes can address knowledge gaps, and behavioural and structural interventions can maximise the impact of HCV care in LMICs.

Hepatitis C treatment and reinfection surveillance among people who inject drugs in a low-threshold program in Oslo, Norway. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 96:103165. [PMID: 33642182 DOI: 10.1016/j.drugpo.2021.103165] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Revised: 01/25/2021] [Accepted: 02/07/2021] [Indexed: 12/16/2022]
Abstract
BACKGROUND The aims were to evaluate HCV treatment effectiveness, estimate reinfection rates, and demonstrate the feasibility of reinfection surveillance and retreatment among marginalized people who inject drugs (PWID). METHODS Prospective observational study including consecutive HCV RNA positive individuals attending a low-threshold clinic in Oslo, Norway, between 2013 and 2020. Participants were offered individually tailored HCV treatment and post-treatment HCV RNA surveillance at three months intervals. RESULTS Of 488 HCV RNA positive individuals, 363 initiated treatment (median age 48.7 years, 72.5% male, 17.2% liver cirrhosis, 54.3% unstable housing). All participants had a history of injecting drug use, 71.1% received opioid agonist treatment, and 70.1% reported recent (past 3 months) injecting. In intention-to-treat analysis, excluding those with HCV RNA results pending, virologic response was achieved in 306 of 340 (90.0%) participants. In modified intention-to-treat analysis, also excluding those with loss to follow-up during treatment, virologic response was achieved in 306 of 323 (94.7%). Virologic response was not associated with recent injecting drug use or socio-demographic factors. Reinfection surveillance was accomplished in 297 individuals (308.2 PY of follow-up; median 0.50 years). Eight cases of reinfection were detected for an incidence of 2.60/100 PY (95% CI 1.12-5.11) overall, and 3.74/100 PY (95% CI 1.62-7.37) among those with injecting drug use during follow-up (n = 205). Reinfection was associated with younger age (IRR 0.37; 95% CI 0.18-0.74), and all cases occurred in participants aged below 49 years with ongoing injecting drug use who reported mixed heroin/amphetamine injecting. Successful retreatment was provided in all cases and no second reinfections were observed. CONCLUSION The findings consolidate previous evidence supporting the effectiveness of HCV treatment among PWID, provide novel data on reinfection rates and associated factors, and demonstrate the feasibility of reinfection surveillance and retreatment in a real-world setting.

Folch C, Saludes V, Reyes-Ureña J, Antuori A, Ibáñez N, Majó X, Colom J, Matas L, Casabona J, Martró E. The hepatitis C care cascade among people who inject drugs accessing harm reduction services in Catalonia: Major gaps for migrants. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 90:103057. [PMID: 33310634 DOI: 10.1016/j.drugpo.2020.103057] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Revised: 11/11/2020] [Accepted: 11/17/2020] [Indexed: 01/03/2023]
Abstract
BACKGROUND This study aimed to describe the HCV cascade of care among people who inject drugs (PWID) in Catalonia, as well as to compare the observed gaps in care between Spanish-born and migrant PWID. METHODS A cross-sectional study of PWID (N = 410) attending four harm reduction services (HRS) was performed in 2016-17 (HepCdetect II Study). Participants were tested for both HCV antibodies (rapid testing) and RNA (from dried blood spot samples). The HCV care cascade was estimated from HCV testing results combined with self-reported data on previous testing, diagnosis and treatment collected through a questionnaire. Logistic regressions were used to test for an association between migration status and the proportions observed in each step of the HCV care cascade adjusting for age, sex, years of injection, homelessness, and treatment for drug dependence. RESULTS Overall, 85.4% were men and 28.0% were migrants. Among Spanish-born (n = 295) and migrant (n = 115) PWID participants in the study, 96.6% vs. 88.6% had previously been HCV screened (AOR=3.11; 95% CI: 1.11-8.65), 79.3% vs. 80.9% were antibody positive, and 70.7% vs. 67.6% were HCV-RNA positive or cured with treatment; among the latter, 36.6% vs. 18.2% had started treatment (AOR=2.41; 95% CI: 1.09-5.34), and 20.6% vs. 9.1% had been cured by treatment, respectively. Unawareness of having hepatitis C was more common among migrants than Spanish-born PWID (46.0% and 31.5%, respectively; p<0.05). CONCLUSION This study estimates the HCV care cascade among Spanish-born and migrant PWID in Catalonia for the very first time, and highlights a higher attrition of migrant PWID in all HCV care cascade stages. The observed limited linkage to care and treatment by PWID that attend the HRS network warrants future implementation of decentralized diagnosis and antiviral treatment. Strategies focusing on migrants by increasing HCV screening coverage and treatment access will be especially relevant in our setting.

HCV testing and treatment initiation in an Italian prison setting: A step-by-step model to micro-eliminate hepatitis C. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 90:103055. [PMID: 33310637 DOI: 10.1016/j.drugpo.2020.103055] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Revised: 11/07/2020] [Accepted: 11/09/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND HCV infection among vulnerable populations is currently a major issue for HCV elimination program. Incarcerated people and people who inject drugs (PWIDs) are key population groups potentially at high risk for HCV infection. Our aim was to evaluate an extended program of screening, staging and treatment in Italian prison settings. METHODS Patients from eight prisons in five different Italian Regions were enrolled. HCV saliva test (QuickOral Test®) was offered. Data on infection awareness and illicit drug use were also collected. Positive patients underwent early HCV RNA evaluation, staging and prescription on DAAs treatment. The definition of PWID was based on self-reported injecting drug use extracted from medical records (injecting drug use during the previous six months). RESULTS A total of 2,376 out of 2,687 individuals (88%) was tested. The median (IQR) age was 42 (32-50) years. PWIDs were 537out of 2,376 (23%). Prevalence of HCV antibodies was 10.4% (248/2,376). PWIDs had a lower awareness of their HCV-Ab positivity than non-PWIDs (p-value <0.001). Furthermore, PWIDs were less likely to be previously treated than non-PWIDs (78% vs 96%, p-value= 0.017). Active infection was found in 41% of patients (101/248). Overall, 61% HCV-positive were PWIDs, with 44% HCV RNA positive. HCV therapy was prescribed to 83% (84/101) of patients with active HCV infection and 67% of these (56/84) were PWIDs. Prescription for HCV treatment in PWIDs accounted for 84% (56/67) (while for non-PWIDs was 82% (28/34) p-value: 0.88. Seventeen patients were referred to a Specialist in other prisons because they were going to be transferred soon to another prison. EOT, as well as SVR12 were achieved in 98% (82/84) treated patients. CONCLUSIONS Among patients, PWIDs had a lower awareness of their HCV-Ab positivity and had previously received less treatments. Saliva test allowed to achieve a more rapid result, stage, and treatment approach. More than 80% of patients underwent treatment, without differences between PWIDs and non-PWIDs. Linkage to care during prison transfer allowed to avoid unplanned interruptions and offered more chances to reach the end of treatment.

Abstract
People in prison represent a high-risk population for HCV infection control. With the advent of new direct antiviral agents (DAAs) HCV micro-elimination in prison setting became a feasible strategy. We assessed the impact of an intervention for HCV testing and treatment in 2017 and 2018 in a jail (San Vittore,SV) and a prison for sentenced individuals (Opera,OP). A dedicated protocol was applied and implemented over the two years. We collected data on demographics, HCV testing and treatment on all inmates present on 31 October 2017 and 2018. In the two facilities, there were 2,366 and 2,369 inmates in 2017 and 2018 respectively; the majority were men (95.6%; 96.4%) and Italians (57.0%; 61.9%) with a median age of 41 years. Prevalence of lifetime reported drug use remained high (46.5%; 44.2%). HCV screening coverage was 89% in both years, while HCV RNA test coverage increased (90.6%; 99.0%). HCV seroprevalence remained stable (10.1%; 9.2%). In 2017 among inmates with HCV chronic infection 90 (42.4%) individuals had started DAAs treatment and 106 (54.6%) in 2018; of whom 38 (17.9%) and 74 (38.1%) achieved the SVR. The viremic pool decreased significantly over time (SV,24.4%; 15.4%;OP, 16.1%; <1%). Among inmates with HCV-positive serology in 2018, 121 (81.0%) were never linked to care before incarceration. Our study showed how a targeted and well-implemented HCV test-and-treat intervention in prison was feasible and effective in achieving micro-elimination. Viral hepatitis elimination agenda may help drawing interest onto this neglected population and bringing prison health higher up in the global public health agenda.

Abstract
INTRODUCTION The drug-injecting population has a high prevalence of hepatitis C virus (HCV) and high risk of transmission. It is a priority to establish an agile diagnostic and treatment plan. OBJECTIVES 1) Assess the effectiveness of a new coordinated care plan of referral from the Comprehensive Care Centre for Drug Addicts (CAID) to specialised care and 2) Determine the prevalence of HCV, clinical characteristics, effectiveness and safety of treatment in this population. METHODS 1,300 serologies requested by the CAID between 1998 and 2018 were retrospectively analysed, the seroprevalence of HCV was calculated and the efficiency of the traditional CAID-specialised care referral system was evaluated. A care plan was designed and coordinated among specialists involved in diagnosis and treatment. Since October 2018, 11 patients have been included in the new plan and the performance of both referral systems was compared. RESULTS With the traditional system, 48.2% (83/172) of the patients were lost. 14.5% (172/1,300) presented positive HCV serology, compared to the general population OR = 19; 95% CI 14.3-25. The prevalence of active infection was 80.3% (90/112). The prevalence of active infection was 80.3% (90/112). Of the 11 patients referred by the new plan, 76.9% (8/11) had active infection and 100% (8/8) were treated with Direct Antiviral Agents successfully. CONCLUSIONS The new coordinated CAID-specialised care plan presents high effectiveness in comparison with the traditional referral system. The seroprevalence and prevalence of active infection in the CAID population is very high. Treatments with Direct Antiviral Agents are effective and safe.

Abstract
BACKGROUND Most people diagnosed with hepatitis C virus (HCV) have not linked to care, despite the availability of safe and effective treatment. We aimed to understand why people diagnosed with HCV have not pursued care in the non-urban Southern United States. METHODS We conducted a survey and semi-structured interview with participants referred to an HCV clinic who did not attend an appointment between 2014 and 2018. Our clinic is located in a non-urban region of Virginia at a university hospital. Qualitative data collection was guided by the Health Belief Model (HBM). Data was analyzed using qualitative content analysis to identify key factors influencing patient perceptions regarding HCV and pursuit of care. RESULTS Over half of previously referred patients (N = 200) could not be reached by phone. Eleven participants enrolled, including 7 men and 4 women. Based on survey responses, unreliable transportation, unstable housing, substance use, and lack of insurance were common. Participants demonstrated good knowledge of HCV disease, complications, and treatment. On qualitative analysis of semi-structured interviews, final themes emerged from within and between HBM constructs. Emerging themes influencing patient perceptions included (1) structural barriers, (2) stigma, (3) prior experiences of HCV disease and treatment, (4) discordance between the recognized severity of HCV and expected impacts on one's own health, and (5) patient-provider relationship. Substance use was not identified to be a barrier to care. CONCLUSIONS Participants perceived individual and structural barriers to linking to care. A strong HCV knowledge base was not sufficient to motivate pursuit of care. Efforts to improve linkage to care must address barriers at multiple levels, and system-level changes are needed. As the majority of previously referred patients could not be contacted by phone, current approaches to patient engagement are not effective for reaching these populations. Expansion of HCV care to primary care settings with an established patient-provider relationship or co-located treatment within substance use treatment programs may serve to increase access to HCV treatment.

Abstract
OBJECTIVE Hepatitis C virus (HCV) disproportionately affects those with mental health disorders and those with substance use, and the increasing HCV transmission in the United States is driven by the opioid epidemic. However, patients with a mental health disorder, substance use, or combination of both historically have had limited access to HCV treatment. The goal of our study was to compare sustained virologic response (SVR) rates of HCV treatment with direct-acting antivirals (DAAs) between subjects with and without a mental health disorder, substance use, or combination of both. METHODS We performed a retrospective chart review at 1 Veterans affairs medical center of patients enrolled in the hepatitis C pharmacy clinic who completed DAA treatment from August 17, 2013 to August 17, 2017. The participants (N = 833 patients) were categorized into 2 groups: those with at least 1 mental health disorder, substance use, or combination of both and those without. Baseline variables relevant to HCV treatment, DAA regimen, number of documented efforts to engage patients, and SVR data were collected. RESULTS Of the 833 study participants, 579 patients had a mental health disorder, substance use, or combination of both. The 3 most prevalent disorders were patient-reported substance use (n = 333), substance-related and addictive disorders (n = 176), and depressive disorders (n = 159). The SVR rates and number of documented efforts to engage patients before and during treatment through SVR laboratory completion between those with a mental health disorder, substance use, or combination of both and those without were not statically significant. CONCLUSION DAA-based HCV treatment is highly effective with SVR rates exceeding 95% in the entire study cohort, including patients with or without mental health disorders, substance use, or combination of both.

Hepatitis C Reinfection in People Who Inject Drugs in Resource-Limited Countries: A Systematic Review and Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17144951. [PMID: 32659974 PMCID: PMC7400365 DOI: 10.3390/ijerph17144951] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Revised: 07/01/2020] [Accepted: 07/07/2020] [Indexed: 12/12/2022]
Abstract
Hepatitis C (HCV) is a global pandemic. The World Health Organization has developed a strategic plan for HCV elimination that focuses on low- and middle-income countries (LMICs) and high-risk populations, including people who inject drugs (PWID). While direct-acting antiviral (DAA) therapies are highly effective at eliminating HCV infections and have few side effects, medical professionals and policymakers remain concerned about the risk of reinfection among PWID. This study is a systematic review of research measuring the rate of HCV reinfection among PWID in LMICs and identifies additional areas for further research. A systematic search strategy was used to identify studies documenting HCV reinfection after sustained virologic response in PWID in LMICs. We refined results to include studies where at least 50% of participants had DAA treatment for primary HCV infection. Pooled reinfection rate was calculated across all studies. Seven studies met eligibility criteria. Most studies were conducted in six upper middle-income countries (Mexico, Romania, Russia, Taiwan, Georgi, and Brazil) and one lower middle-income country (Bangladesh) with a total of 7665 participants. No study included information from PWID in low-income countries. Sample sizes ranged from 200 to 3004 individuals, with demographic data missing for most participants. Four studies used deep gene sequencing, and reflex genotyping procedures to differentiate reinfection (infection by a different HCV genotype/subtype) from virologic relapse (infection by the same strain). The follow-up time of people cured from primary chronic HCV infection ranged from 12 weeks to 6.6 years. The pooled reinfection rate of all seven studies was 2.8 (range: 0.02 to 10.5) cases per 100 person-years (PY). In the five studies that differentiated relapse from reinfection, the incidence of reinfection was 1.0 per 100 PY. To date, research on reinfection rates among PWID in LMICs remains limited. Research focused on PWID in low-income countries is particularly needed to inform clinical decision making and evidence-based programs. While rates of reinfection among PWID who complete DAA treatment in upper and lower middle-income countries were similar or lower than rates observed in PWID in high-income countries, the rates were highly variable and factors may influence the accuracy of these measurements. This systematic review identifies several areas for continued research. Policies concerning access to HCV testing and treatment should be comprehensive and not place restrictions on PWID in these settings.

Opportunistic treatment of hepatitis C virus infection (OPPORTUNI-C): study protocol for a pragmatic stepped wedge cluster randomized trial of immediate versus outpatient treatment initiation among hospitalized people who inject drugs.

Abstract
Background Scaled-up direct-acting antiviral (DAA) treatment of hepatitis C virus (HCV) infection among people who inject drugs (PWID) is crucial to reach the World Health Organization HCV elimination targets within 2030. One of the critical obstacles to HCV care in this population is the lack of treatment models within specialist healthcare adapted to marginalized individuals. Methods OPPORTUNI-C is a pragmatic stepped wedge cluster randomized trial comparing the efficacy of immediate initiation of HCV treatment with the current standard of care among PWID admitted for inpatient care. Screening for HCV RNA will be performed as soon as possible after admission. The intervention includes immediate non-invasive liver disease assessment, counseling, and initiation of pan-genotypic DAA treatment with individualized follow-up. Standard of care is a referral to outpatient care at discharge. To mimic usual clinical practice as closely as possible, we will use a pragmatic clinical trial approach utilizing clinical infrastructure, broad eligibility criteria, flexible intervention delivery, clinically relevant outcomes, and collection of data readily available from the electronic patient files. The stepped wedge design involves a sequential rollout of the intervention over 16 months, in which seven participating clusters will be randomized from standard of care to intervention in a stepwise manner. Randomization will be stratified according to cluster size to keep high prevalence clusters separated. The trial will include approximately 220 HCV RNA positive individuals recruited from departments of internal medicine, addiction medicine, and psychiatry at Akershus University Hospital, Oslo University Hospital, and Lovisenberg Diaconal Hospital, Oslo, Norway. Individuals not able or willing to give informed consent and those with ongoing HCV assessment or treatment will be excluded. The primary outcome is treatment completion, defined as dispensing of the final prescribed DAA package from the pharmacy within 6 months after inclusion. Secondary outcomes include treatment uptake, virologic response, reinfection incidence, and resistance-associated substitutions. Discussion Representing a novel model of care suited to reach and engage marginalized PWID in HCV care, this study will inform HCV elimination efforts locally and internationally. If the model proves efficacious and feasible, it should be considered for broader implementation, replacing the current standard of care. Trial registration ClinicalTrials.gov, NCT04220645.

Economic Evaluation of Hepatitis C Treatment Extension to Acute Infection and Early-Stage Fibrosis Among Patients Who Inject Drugs in Developing Countries: A Case of China. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17030800. [PMID: 32012839 PMCID: PMC7037788 DOI: 10.3390/ijerph17030800] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/05/2019] [Revised: 01/22/2020] [Accepted: 01/24/2020] [Indexed: 12/20/2022]
Abstract
We aimed to assess the cost-effectiveness of (1) treating acute hepatitis C virus (HCV) vs. deferring treatment until the chronic phase and (2) treating all chronic patients vs. only those with advanced fibrosis; among Chinese genotype 1b treatment-naïve patients who injected drugs (PWID), using a combination Daclatasvir (DCV) plus Asunaprevir (ASV) regimen and a Peg-interferon (PegIFN)-based regimen, respectively. A decision-analytical model including the risk of HCV reinfection simulated lifetime costs and quality-adjusted life-years (QALYs) of three treatment timings, under the DCV+ASV and PegIFN regimen, respectively: Treating acute infection (“Treat at acute”), treating chronic patients of all fibrosis stages (“Treat at F0 (no fibrosis)”), treating only advanced-stage fibrosis patients (“Treat at F3 (numerous septa without cirrhosis)”). Incremental cost-effectiveness ratios (ICERs) were used to compare scenarios. “Treat at acute” compared with “Treat at F0” was cost-saving (cost: DCV+ASV regimen—US$14,486.975 vs. US$16,224.250; PegIFN-based regimen—US$19,734.794 vs. US$22,101.584) and more effective (QALY: DCV+ASV regimen—14.573 vs. 14.566; PegIFN-based regimen—14.148 vs. 14.116). Compared with “Treat at F3”; “Treat at F0” exhibited an ICER of US$3780.20/QALY and US$15,145.98/QALY under the DCV+ASV regimen and PegIFN-based regimen; respectively. Treatment of acute HCV infection was highly cost-effective and cost-saving compared with deferring treatment to the chronic stage; for both DCV+ASV and PegIFN-based regimens. Early treatment for chronic patients with DCV+ASV regimen was highly cost-effective.
