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 Progress toward hepatitis C virus (HCV) elimination is impeded by low testing and treatment due to the current diagnostic pathway requiring multiple visits leading to loss to follow-up. Point-of-care testing technologies capable of detecting current HCV infection in one hour are a 'game-changer.' These tests enable diagnosis and treatment in a single visit, overcoming the barrier of multiple visits that frequently leads to loss to follow-up. Combining point-of-care HCV antibody and RNA tests should improve cost-effectiveness, patient/provider acceptability, and testing efficiency. However, implementing HCV point-of-care testing programs at scale requires multiple considerations. AREAS COVERED This commentary explores the need for point-of-care HCV tests, diagnostic strategies to improve HCV testing, key considerations for implementing point-of-care HCV testing programs, and remaining challenges for point-of-care testing (including operator training, quality management, connectivity and reporting systems, regulatory approval processes, and the need for more efficient tests). EXPERT OPINION It is exciting that single-visit testing, diagnosis, and treatment for HCV infection have been achieved. Innovations afforded through COVID-19 should facilitate the accelerated development of low-cost, rapid, and accurate tests to improve HCV testing. The next challenge will be to address barriers and facilitators for implementing point-of-care testing to deliver them at scale.

Cost-effectiveness of integrated treatment for hepatitis C virus (HCV) among people who inject drugs in Norway: An economic evaluation of the INTRO-HCV trial. Addiction 2023; 118:2424-2439. [PMID: 37515462 PMCID: PMC10952903 DOI: 10.1111/add.16305] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Accepted: 06/26/2023] [Indexed: 07/30/2023]
Abstract
BACKGROUND AND AIMS The INTRO-HCV randomized controlled trial conducted in Norway over 2017-2019 found that integrated treatment, compared with standard-of-care hospital treatment, for hepatitis C virus (HCV) with direct-acting antivirals (DAAs) improved treatment outcomes among people who inject drugs (PWID). We evaluated cost-effectiveness of the INTRO-HCV intervention. DESIGN A Markov health state transition model of HCV disease progression and treatment with cost-effectiveness analysis from the health-provider perspective. Primary cost, utility, and health outcome data were derived from the trial. Costs and health benefits (quality-adjusted life-years, QALYs) were tracked over 50 years. Probabilistic and univariate sensitivity analyses investigated DAA price reductions and variations in HCV treatment and disease care cost assumptions, using costs from different countries (Norway, United Kingdom, United States, France, Australia). SETTING AND PARTICIPANTS PWID attending community-based drug treatment centers for people with opioid dependence in Norway. MEASUREMENTS Incremental cost-effectiveness ratio (ICER) in terms of cost per QALY gained, compared against a conventional (€70 000/QALY) willingness-to-pay threshold for Norway and lower (€20 000/QALY) threshold common among high-income countries. FINDINGS Integrated treatment resulted in an ICER of €13 300/QALY gained, with 99% and 71% probability of being cost-effective against conventional and lower willingness-to-pay thresholds, respectively. A 30% lower DAA price reduced the ICER to €6 900/QALY gained, with 91% probability of being cost-effective at the lower willingness-to-pay threshold. A 60% and 90% lower DAA price had 36% and >99% probability of being cost-saving, respectively. Sensitivity analyses suggest integrated treatment was cost-effective at the lower willingness-to-pay threshold (>60% probability) across different assumptions on HCV treatment and disease care costs with 30% DAA price reduction, and became cost-saving with 60%-90% price reductions. CONCLUSIONS Integrated hepatitis C virus treatment for people who inject drugs in community settings is likely cost-effective compared with standard-of-care referral pathways in Norway and may be cost-saving in settings with particular characteristics.

Abstract
BACKGROUND Psycho-social experiences including shame and experienced and internalized stigma have been associated with substance use, HCV infection, and reluctance to disclose HCV status and pursue treatment. These psycho-social barriers have been examined independently for many chronic diseases, including HCV, but to our knowledge have not been quantitatively explored in a large multi-site US-based sample of people who inject drugs (PWID) in HCV treatment. METHODS We examine baseline relationships with HCV-stigma and engagement across the HCV treatment cascade as well as baseline and longitudinal relationships between shame and engagement across the HCV treatment cascade including treatment initiation, adherence, completion, and sustained virologic response (SVR) among a multi-site sample of PWID with HCV, where N=755 were randomized to the pragmatic trial comparing HCV treatment outcomes in modified directly observed treatment (mDOT) or patient navigation, and N=623 initiated treatment. RESULTS While cross-sectional assessments of shame and HCV-stigma were not associated with engagement across the HCV treatment cascade, those whose shame scores decreased compared to those who reported consistently high and increasing levels of shame were significantly more likely to complete HCV treatment (aOR=5.29; 95%CI: 1.56,18.00) and achieve SVR (aOR=6.32; 95%CI: 1.61, 24.87). CONCLUSION Results underscore the relationships between lower levels of shame and health-related behavior and treatment outcomes among PWID and suggest SVR achievement may contribute to reductions in shame or that reductions in shame may contribute to continued treatment and thus SVR.

Abstract
Background Hepatitis C virus (HCV) is a universally prevalent pathogen and a major cause of liver-related morbidity and mortality worldwide. The evolution of antiviral therapy for HCV has rapidly progressed from interferon (IFN)-based therapies to IFN-free combinations of direct-acting antivirals (DAAs). Aims This study aims to assess the response of DAAs in chronic hepatitis C (CHC) patients and to study the various factors affecting the response of DAAs in CHC. Settings and Design This longitudinal observational study spanning over a year was conducted in the Medicine department of a tertiary care teaching hospital. Materials and Methods The study was conducted on 400 adult CHC patients, diagnosed by a positive anti-HCV antibody test and a detectable viral load (HCV RNA) by real time polymerase chain reaction (RT-PCR), registered for treatment with DAAs. The first 400 patients satisfying the eligibility criteria were enrolled by non-probability consecutive sampling. All the participants were treated as per the National Viral Hepatitis Control Programme (NVHCP) guidelines. Repeat HCV viral load was done at or after 12 weeks of completion of anti-viral therapy to ascertain sustained virological response (SVR). Various factors which might predict treatment response were analyzed. Statistical Analysis Used The continuous variables were expressed as mean and standard deviation, while the categorical variables were summarized as frequencies and percentages. The Student's independent t-test was employed for the comparison of continuous variables. The Chi-square or Fisher's exact test, whichever is appropriate, was employed for the comparison of categorical variables. Multivariate Logistic Regression was used to identify the independent predictors of treatment nonresponse. A P < 0.05 was considered statistically significant. Results The mean age of the subjects was 42.3 ± 15.23 years with a male-to-female ratio of 1.96:1. Most of the patients (80.5%) were non-cirrhotic; among 19.5% cirrhotic, 13% were compensated while 6.5% were decompensated cirrhotic. The overall SVR done at or after 12 weeks of completion of treatment was 88.75%. Age, gender distribution, occupation, socioeconomic status, educational status, body mass index, treatment regimen, duration of treatment, and baseline viral load did not alter the treatment response. Among comorbidities, only diabetes mellitus (DM) and human immunodeficiency virus (HIV) co-infection adversely affected the treatment response (P = 0.009 and P < 0.001, respectively). Intravenous (IV) drug abuse was significantly associated with treatment failure (P < 0.001). The presence of liver cirrhosis (P < 0.001), thrombocytopenia (P < 0.001), elevated transaminases (alanine transaminase: P = 0.021, aspartate transaminase: P < 0.001), and previous treatment experience (P = 0.038) were other significant predictors of treatment failure. Conclusions DAAs are highly efficacious drugs in the treatment of CHC with a high rate of treatment response. Significant predictors of CHC treatment failure included comorbidities especially DM and HIV co-infection, IV drug abuse, presence of liver cirrhosis, thrombocytopenia, elevated transaminases, and previous treatment experience. However, independent predictors of treatment nonresponse observed in this study were thrombocytopenia, IV drug abuse, and liver cirrhosis.

Abstract
INTRODUCTION Syringe decriminalization is a harm reduction approach to decrease deaths and disease related to drug use. The purpose of this study was to develop an understanding of the impact of syringe decriminalization on the harm reduction community in Pennsylvania. METHODS Semi-structured interviews were conducted with ten participants identified as harm reduction experts. ANALYSIS Narrative content analysis to the point of thematic saturation was used to generate themes around harm reduction and syringe decriminalization in Pennsylvania, specifically the meaning of harm reduction, the importance of harm reduction, and the opinions on syringe decriminalization. RESULTS The following themes reflect the meaning of harm reduction: human compassion; meeting people where they are at; minimizing the risk; and shifting power to the person. The themes of being personally impacted, human compassion, innate imperfection, and respecting human autonomy reflect why participants care about harm reduction. All ten participants support syringe decriminalization in Pennsylvania citing the following rationales: improved health outcomes; decreased costs to society; less involvement of the criminal justice system; and increased engagement into treatment. CONCLUSIONS Harm reduction is a pioneering approach to drug use that empowers individuals to make positive impacts in their lives. Harm reduction experts in Pennsylvania support syringe decriminalization as a cost-effective way to increase the engagement and improve health outcomes of people who use drugs.

Abstract
Hepatitis C virus (HCV) is a hepatotropic RNA virus that can cause acute and chronic hepatitis, with progressive liver damage resulting in cirrhosis, decompensated liver disease, and hepatocellular carcinoma. In 2016, WHO called for the elimination of HCV infection as a public health threat by 2030. Despite some progress, an estimated 57 million people were living with HCV infection in 2020, and 300 000 HCV-related deaths occur per year. The development of direct-acting antiviral therapy has revolutionised clinical care and generated impetus for elimination, but simplified and broadened HCV screening, enhanced linkage to care, and higher coverage of treatment and primary prevention strategies are urgently required.

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
The World Health Organization (WHO) aims to reduce HCV mortality, but estimates are difficult to obtain. We aimed to identify electronic health records of individuals with HCV infection, and assess mortality and morbidity. We applied electronic phenotyping strategies on routinely collected data from patients hospitalized at a tertiary referral hospital in Switzerland between 2009 and 2017. Individuals with HCV infection were identified using International Classification of Disease (ICD)-10 codes, prescribed medications and laboratory results (antibody, PCR, antigen or genotype test). Controls were selected using propensity score methods (matching by age, sex, intravenous drug use, alcohol abuse and HIV co-infection). Main outcomes were in-hospital mortality and attributable mortality (in HCV cases and study population). The non-matched dataset included records from 165,972 individuals (287,255 hospital stays). Electronic phenotyping identified 2285 stays with evidence of HCV infection (1677 individuals). Propensity score matching yielded 6855 stays (2285 with HCV, 4570 controls). In-hospital mortality was higher in HCV cases (RR 2.10, 95%CI 1.64 to 2.70). Among those infected, 52.5% of the deaths were attributable to HCV (95%CI 38.9 to 63.1). When cases were matched, the fraction of deaths attributable to HCV was 26.9% (HCV prevalence: 33%), whilst in the non-matched dataset, it was 0.92% (HCV prevalence: 0.8%). In this study, HCV infection was strongly associated with increased mortality. Our methodology may be used to monitor the efforts towards meeting the WHO elimination targets and underline the importance of electronic cohorts as a basis for national longitudinal surveillance.

"Treated like a Human Being": perspectives of people who inject drugs attending low-threshold HCV treatment at a syringe service program in New York City. Harm Reduct J 2023; 20:95. [PMID: 37501180 PMCID: PMC10375754 DOI: 10.1186/s12954-023-00831-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 07/16/2023] [Indexed: 07/29/2023] Open
Abstract
BACKGROUND Hepatitis C virus (HCV) treatment can effectively cure HCV among people who inject drugs (PWID). Perspectives of PWID treated in innovative models can reveal program features that address barriers to treatment, and guide implementation of similar models. METHODS We interviewed 29 participants in the intervention arm of a randomized trial. The trial enrolled PWID with HCV in New York City from 2017 to 2020 and tested the effectiveness of a low-threshold HCV treatment model at a syringe services program. Participants were purposively sampled and interviewed in English or Spanish. The interview guide focused on prior experiences with HCV testing and treatment, and experiences during the trial. Interviews were inductively coded and analyzed using thematic analysis. RESULTS Before enrollment, participants reported being tested for HCV in settings such as prison, drug treatment, and emergency rooms. Treatment was delayed because of not being seen as urgent by providers. Participants reported low self-efficacy, competing priorities, and systemic barriers to treatment such as insurance, waiting lists, and criminal-legal interactions. Stigma was a major factor. Treatment during the trial was facilitated through respect from staff, which overcame stigma. The flexible care model (allowing walk-ins and missed appointments) helped mitigate logistical barriers. The willingness of the staff to address social determinants of health was highly valued. CONCLUSION Our findings highlight the need for low-threshold programs with nonjudgmental behavior from program staff, and flexibility to adapt to participants' needs. Social determinants of health remain a significant barrier, but programs' efforts to address these factors can engender trust and facilitate treatment. Trial registration NCT03214679.

Int J Equity Health 2023; 22:112.

Abstract
BACKGROUND Hepatitis C is curable with direct-acting antivirals (DAAs). However, treatment uptake remains low among marginalized populations such as people who inject drugs. We sought to understand challenges to treatment uptake with DAAs among people living with hepatitis C and compare treatment experiences between people who do and do not inject prescription and/or unregulated drugs. METHODS We conducted a qualitative study using focus groups with 23 adults aged 18 years and over who completed DAA treatment or were about to begin such treatment at the time of the study. Participants were recruited from hepatitis C treatment clinics across Toronto, Ontario. We drew upon stigma theory to interpret participants' accounts. RESULTS Following analysis and interpretation, we generated five theoretically-informed themes characterizing the experiences of individuals accessing DAAs: "being 'worthy' of the cure", "spatially enacted stigma", "countering social and structural vulnerability: the importance of peers", "identity disruption and contagion: attaining a 'social cure'" and "challenging stigma with population-based screening". Overall, our findings suggest that structural stigma generated and reproduced through healthcare encounters limits access to DAAs among people who inject drugs. Peer-based programs and population-based screening were proposed by participants as mechanisms for countering stigma within health care settings and 'normalizing' hepatitis C among the general population. CONCLUSIONS Despite the availability of curative therapies, access to such treatment for people who inject drugs is limited by stigma enacted in and structured within healthcare encounters. Developing novel, low-threshold delivery programs that remove power differentials and attend to the social and structural determinants of health and reinfection are needed to facilitate further scale up of DAAs and support the goal of eradicating hepatitis C as a public health threat.

HCV, HIV AND HBV rapid test diagnosis in non-clinical outreach settings can be as accurate as conventional laboratory tests. Sci Rep 2023; 13:7554. [PMID: 37160925 PMCID: PMC10170094 DOI: 10.1038/s41598-023-33925-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Accepted: 04/20/2023] [Indexed: 05/11/2023] Open
Abstract
Point of care rapid diagnostic tests (POC-RDT) for Hepatitis C virus (HCV), Human Immunodeficiency virus (HIV) and Hepatitis B virus (HBV), are ideal for screening in non-clinical outreach settings as they can provide immediate results and facilitate diagnosis, allowing high risk population screening. The aim of this study was to compare POC-RDT with laboratory conventional tests. A total of 301 vulnerable evaluable subjects (drug users, migrants and homeless population) were recruited at a mobile screening unit in outreach settings in Madrid. Fingerprick whole blood capillary samples were tested using the SD BIOLINE HCV POC-RDT, Determine HIV Early Detect and Determine HBsAg 2, and the results were assessed against the LIAISON XL HCV, HIV and Murex-HBsAg-Quant, reference assays, respectively. The feasibility and user satisfaction of the POC-RDT were evaluated through a questionnaire. The resolved sensitivity and resolved specificity and their 95% confidence intervals (95% CI) were as follows, respectively: SD-BIOLINE-HCV: 98.8% (95% CI 93.4, 100.0) and 100.0% (95% CI 98.3, 100.0); Determine HIV Early Detect: 100% (95% CI 85.2, 100.0) and 100% (95% CI 98.7, 100); and Determine HBsAg 2: 66.7% (95% CI 9.4, 99.2) and 100.0% (95% CI 98.7, 100.0). As expected, the number of subjects with a confirmed positive result for HBsAg was very low (n = 4). Therefore, the analytical sensitivity has been evaluated in addition: The Determine HBsAg 2 test demonstrated 100% sensitivity for standard concentrations ≥ 0.125 IU/mL. The subject questionnaire yielded positive feedback for most subjects. The POC-RDT fingerprick blood collection method was well received, and the tests demonstrated a comparable clinical performance with conventional tests in outreach settings and vulnerable high-risk populations.

Abstract
Introduction Early development of broadly neutralizing antibodies (bNAbs) targeting the hepatitis C virus (HCV) envelope glycoprotein E2 is associated with spontaneous clearance of infection, so induction of bNAbs is a major goal of HCV vaccine development. However, the molecular antibody features important for broad neutralization are not known. Methods To identify B cell repertoire features associated with broad neutralization, we performed RNA sequencing of the B cell receptors (BCRs) of HCV E2-reactive B cells of HCV-infected individuals with either high or low plasma neutralizing breadth. We then produced a monoclonal antibody (mAb) expressed by pairing the most abundant heavy and light chains from public clonotypes identified among clearance, high neutralization subjects. Results We found distinctive BCR features associated with broad neutralization of HCV, including long heavy chain complementarity determining region 3 (CDRH3) regions, specific VH gene usage, increased frequencies of somatic hypermutation, and particular VH gene mutations. Most intriguing, we identified many E2-reactive public BCR clonotypes (heavy and light chain clones with the same V and J-genes and identical CDR3 sequences) present only in subjects who produced highly neutralizing plasma. The majority of these public clonotypes were shared by two subjects who cleared infection. A mAb expressing the most abundant public heavy and light chains from these clearance, high neutralization subjects had features enriched in high neutralization clonotypes, such as increased somatic hypermutation frequency and usage of IGHV1-69, and was cross-neutralizing. Discussion Together, these results demonstrate distinct BCR repertoires associated with high plasma neutralizing capacity. Further characterization of the molecular features and function of these antibodies can inform HCV vaccine development.

Modeling the Impacts of Prevention and Treatment Interventions on Hepatitis C Among People Who Inject Drugs in China. Infect Dis Ther 2023; 12:1043-1055. [PMID: 36894824 PMCID: PMC10147892 DOI: 10.1007/s40121-023-00779-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Accepted: 02/10/2023] [Indexed: 03/11/2023] Open
Abstract
INTRODUCTION Injection drug use is the main transmission route of hepatitis C virus (HCV) in China. The prevalence of HCV remains high at 40-50% among people who inject drugs (PWID). We developed a mathematical model to predict the impacts of different HCV intervention strategies on the HCV burden in Chinese PWID by 2030. METHODS We developed a dynamic deterministic mathematical model to simulate the transmission of HCV among PWID in China between 2016 and 2030, using domestic data based on the real cascade of HCV care. We considered various intervention scenarios, including treatment regimens, harm reduction program (HRP) coverage, enhanced testing and referral for treatment. RESULTS HCV incidence will exhibit a gradual but slow declining trend from 12,970 in 2016 to 11,761 in 2030 based on current screening and treatment practices among PWID (scenario 1). Scaled-up HCV screening and treatment integrated with HRPs (scenario 8) demonstrated the most substantial reduction in HCV burden, being the only intervention scenario that could achieve the World Health Organization's (WHO's) HCV elimination target. Specifically, the HCV incidence in 2030 is projected to be reduced by 81.42%, and HCV-related deaths are projected to be reduced by 91.94%. CONCLUSION Our study indicates that achieving WHO elimination targets is an extremely challenging goal that requires substantial improvements in HCV testing and treatment among PWID (scenario S8). The findings suggest that coordinated improvements in testing, treatment, and harm reduction programs could greatly reduce the HCV burden among PWID in China, and urgent policy changes are needed to integrate HCV testing and treatment into existing HRPs.

Abstract
BACKGROUND & AIMS People who inject drugs (PWID) experience high incarceration rates which are associated with increased hepatitis C virus (HCV) transmission risk. We assess the importance of prison-based interventions for achieving HCV elimination among PWID in New South Wales (NSW), Australia. METHODS A model of incarceration and HCV transmission among PWID was calibrated in a Bayesian framework to epidemiological and incarceration data from NSW, incorporating elevated HCV acquisition risk among recently released PWID. We projected the contribution of differences in transmission risk during/following incarceration to HCV transmission over 2020-2029. We estimated the past and potential future impact of prison-based opioid agonist therapy (OAT; ~33% coverage) and HCV treatment (1500 treatments in 2019 with 32.9%-83.3% among PWID) on HCV transmission. We estimated the time until HCV incidence reduces by 80% (WHO elimination target) compared to 2016 levels with or without prison-based interventions. RESULTS Over 2020-2029, incarceration will contribute 23.0% (17.9-30.5) of new HCV infections. If prison-based interventions had not been implemented since 2010, HCV incidence in 2020 would have been 29.7% (95% credibility interval: 22.4-36.1) higher. If current prison and community HCV treatment rates continue, there is an 98.8% probability that elimination targets will be achieved by 2030, with this decreasing to 10.1% without current prison-based interventions. CONCLUSIONS Existing prison-based interventions in NSW are critical components of strategies to reduce HCV incidence among PWID. Prison-based interventions are likely to be pivotal for achieving HCV elimination targets among PWID by 2030.

HCV treatment initiation in the era of universal direct acting antiviral coverage - Improvements in access and persistent barriers. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 113:103954. [PMID: 36758334 DOI: 10.1016/j.drugpo.2023.103954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Revised: 01/04/2023] [Accepted: 01/05/2023] [Indexed: 02/10/2023]
Abstract
BACKGROUND Barriers to HCV treatment initiation persisted after the introduction of direct-acting antivirals (DAAs) in Canada among people who inject drugs (PWID); whether DAA universal coverage lifted these barriers remain unknown. We assessed the evolution of HCV treatment initiation and associated factors among PWID in Montreal, Canada, comparing eras of IFN-based regimens (2011-2013), of DAA restricted access (2014-02/2018), and universal coverage (03/2018-03/2020). METHODS We included chronically HCV-infected participants followed in a community-based PWID cohort in Montreal, Canada between 2011 and 03/2020 and collected data at 3-month intervals. Time-updated Cox regressions were conducted to examine 9 variables of interest associated with treatment initiation overall and for each of the three eras. RESULTS Of 276 participants, 126 initiated treatment during follow-up. Yearly initiation increased from 3% in 2011 to 19% in 2016, and 54% in 2018. PWID aged >40 (vs. ≤40) were twice as likely to initiate treatment in 2014-02/2018 (HR: 2.02 95%CI: [1.24-3.28]) but not in other periods (2011-2013: 0.55 [0.25-1.22]; 03/2018-03/2020: 1.14 [0.59-2.22])). Odds of initiation were lower for men than women in all periods, with women three times more likely to be treated under universal coverage (0.30 [0.11-0.77] vs 2011-2013: 0.67 [0.25-1.78] and 2014-02/2018: 0.75 [0.42-1.35]). Recent incarceration was negatively associated with initiation throughout all periods (2011-2013: 0.57 [0.13-2.43]; 2014-03/2018: 0.39 [0.17-0.91]; 03/2018-03/2020: 0.25 [0.07-0.83]). Barriers associated with high injection frequency appear to have diminished since DAA introduction (2014-02/2018: 0.71 [0.42-1.20]; 03/2018-03/2020: 1.05 [0.52-2.11] vs. 2011-2013: 0.26 [0.08-0.88]). Contact with a primary care physician and engagement in opioid agonist therapy were positively associated with treatment initiation, though estimates were attenuated under universal coverage relative to previous eras. CONCLUSION Treatment initiation rates have increased since the introduction of universal DAA coverage, though barriers such as incarceration persist.

Abstract
Background and aims The burden hepatitis C infection in people with history or current drug use suppose a high risk of hepatic complications and transmission infectious disease. This population is poor linked to heath system and is difficult to achieve them and support treatment because they have high rates of lost follow-up. Our aim was to evaluate an intervention for the diagnosis and treatment of chronic hepatitis C and HIV in this population. Methods Six-hundred and eighty-three people attended in Drugs and Addictions Centers (DAC) were asked to participate in health counseling and provide blood sample for test HCV, HIV, and syphilis from April 2019 to June 2020. Totally 556 subjects were surveyed and tested. All of them were assigned to a patient navigation program to improve health education and linking to the sanitary system. Hepatitis C infection patients were evaluated in an ampliated medical consult to evaluate hepatic stage with transient liver elastography and initiated Direct Acting Antivirals to achieve Sustained Viral Response. Results Of the 556 patients who agreed to participate in the study, 33 (5.9%) had active HCV infection. Of the 33 patients infected with HCV, three were lost to follow-up once the diagnosis of HCV infection was made. Twenty-eight patients (93.3%) completed treatment and 26 achieved Sustained Viral Response (78.8%). Of the 30 patients, seven (23.3%) had advanced fibrosis, and of these, four (16.6%) had liver cirrhosis. One of the cirrhotic patients had hepatic space-occupying lesions at the baseline evaluation and was diagnosed with hepatocarcinoma. Conclusions Our study suggests that the implementation of strategies based on personalized intervention models can contribute to the control of HCV infection in DAC users.

Integrated supervised consumption services and hepatitis C testing and treatment among people who inject drugs in Toronto, Canada: A cross-sectional analysis. J Viral Hepat 2023; 30:160-171. [PMID: 36461705 DOI: 10.1111/jvh.13780] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 10/31/2022] [Accepted: 11/25/2022] [Indexed: 12/09/2022]
Abstract
Despite the availability of publicly funded hepatitis C (HCV) treatment in Canada, treatment gaps persist, particularly among people who inject drugs. We estimate correlates of HCV care cascade engagement (testing, diagnosis, and treatment) among people who inject drugs in Toronto, Canada and examine the effect of accessing differing supervised consumption service (SCS) models on self-reported HCV testing and treatment. This is a cross-sectional baseline analysis of 701 people who inject drugs surveyed in the Toronto, Ontario integrated Supervised Injection Services (OiSIS-Toronto) study between November 2018 and March 2020. We examine correlates of self-reported HCV care cascade outcomes including SCS model, demographic, socio-structural, drug use, and harm reduction characteristics. Overall, 647 participants (92%) reported ever receiving HCV testing, of whom 336 (52%) had been diagnosed with HCV. Among participants who reported ever being diagnosed with HCV, 281 (84%) reported chronic HCV, of whom 130 (46%) reported HCV treatment uptake and 151 (54%) remained untreated. Compared to those with no SCS use, participants who had ever injected at an integrated SCS model with co-located HCV care had greater prevalence of both ever receiving HCV testing (adjusted prevalence ratio [aPR]: 1.12, 95% confidence interval [CI]: 1.02-1.24) and ever receiving HCV treatment (aPR: 1.67, 95% CI: 1.04-2.69). Over half of participants diagnosed with chronic HCV reported remaining untreated. Our findings suggest that integrated SCS models with co-located HCV care represent key strategies for linkage to HCV care, but that more is needed to support scale-up.

How the rural risk environment underpins hepatitis C risk: Qualitative findings from rural southern Illinois, United States. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 112:103930. [PMID: 36641816 PMCID: PMC9974910 DOI: 10.1016/j.drugpo.2022.103930] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 12/01/2022] [Accepted: 12/05/2022] [Indexed: 01/15/2023]
Abstract
BACKGROUND Hepatitis C virus (HCV) infection has increased among persons who inject drugs (PWID) in the United States with disproportionate burden in rural areas. We use the Risk Environment framework to explore potential economic, physical, social, and political determinants of hepatitis C in rural southern Illinois. METHODS Nineteen in-depth semi-structured interviews were conducted with PWID from August 2019 through February 2020 (i.e., pre-COVID-19 pandemic) and four with key informants who professionally worked with PWID. Interviews were recorded, professionally transcribed, and coded using qualitative software. We followed a grounded theory approach for coding and analyses. RESULTS We identify economic, physical, policy, and social factors that may influence HCV transmission risk and serve as barriers to HCV care. Economic instability and lack of economic opportunities, a lack of physically available HCV prevention and treatment services, structural stigma such as policies that criminalize drug use, and social stigma emerged in interviews as potential risks for transmission and barriers to care. CONCLUSION The rural risk environment framework acknowledges the importance of community and structural factors that influence HCV infection and other disease transmission and care. We find that larger structural factors produce vulnerabilities and reduce access to resources, which negatively impact hepatitis C disease outcomes.

Abstract
BACKGROUND People who inject drugs (PWID) continue to experience the highest burden of hepatitis C virus (HCV). We aimed to characterize HCV antibody prevalence, determinants of infection, and the cascade of engagement in HCV care among PWID in Iran. METHODS Participants were recruited in 11 cities of Iran using respondent-driven sampling. PWID underwent a structured interview capturing measures on socio-demographics, behaviors, and the HCV cascade of care. HCV and HIV were tested using antibody rapid tests. Multivariable logistic regression models identified characteristics associated with HCV seropositivity. RESULTS HCV antibody prevalence was 26.0% among 2684 PWID enrolled. Of 699 participants who were HCV antibody positive, 88 (12.6%) were aware of past infections. HCV antibody prevalence was associated with older age (adjusted odds ratio [aOR] 2.09; 95% CI 1.18, 3.71), lower education (aOR 1.31; 95% CI 1.02, 1.69), >10 years of injecting (aOR 6.03; 95% CI 4.10, 8.85), methamphetamine injection (aOR 1.46; 95% CI 1.07, 1.99), daily injection drug use (aOR 1.26; 95% CI 1.01, 1.58), needle/syringe sharing (aOR 2.04; 95% CI 1.24, 3.34), recent incarceration (aOR 1.74; 95% CI 1.30, 2.32), and HIV seropositivity (aOR 7.93; 95% CI 4.12, 15.24). Additionally, 12.0% had ever tested for HCV, 4.0% had previously tested reactive for HCV antibody, and 3.7% had received an HCV diagnosis. Of diagnosed cases, 44.4% were linked to care, 15.2% initiated treatment, and 3.0% achieved sustained virologic response. CONCLUSION Our data show a high prevalence of HCV antibody and low engagement in HCV care, underscoring an unmet need for HCV prevention, screening, and treatment among PWID in Iran. HCV prevention and treatment programs tailored for PWID are needed to enhance harm reduction efforts and access to HCV care in Iran.

Modeling HCV elimination recovery following the COVID-19 pandemic in the United States: Pathways to regain progress. J Infect Public Health 2023; 16:64-70. [PMID: 36473359 PMCID: PMC9674561 DOI: 10.1016/j.jiph.2022.11.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 10/20/2022] [Accepted: 11/15/2022] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND As of 2019, the United States (US) was not on track to achieve targets for elimination, due to increasing incidence and treatment barriers. In 2020, the COVID-19 pandemic disrupted HCV services globally and in the US. As healthcare services normalize, there is an urgent need to reassess progress and evaluate scenarios that restore a pathway toward HCV elimination. METHODS We updated a validated Markov model to estimate HCV-related morbidity and mortality in the US. Five scenarios were developed to bookend possible HCV outcomes in the wake of the pandemic. These included 1) return to pre-COVID-19 treatment forecasts; 2) achieve elimination targets through treatment and harm reduction; 3) long-term treatment disruptions; 4/5) achieve elimination targets through increased treatment without increased harm reduction, starting in either 2022 or 2025. FINDINGS From 2014-2019, more than 1.2 million patients were treated for HCV in the US. Elimination targets in 2030 could be achieved in the US by treating an additional 3.2-3.3 million patients from 2020 to 2030, or by preventing new infections through expanded harm reduction programs and treating up to 2.7 million patients. Intervention scenarios could prevent over 30,000 HCC cases and over 29,000 liver-related deaths. INTERPRETATION The US has made strides toward HCV elimination, but gains could be lost in the wake of the pandemic. However, it is still possible to avert nearly 30,000 deaths through increased harm reduction and increased treatment rates. This requires a coordinated effort from the entire HCV community.

HCV microelimination in harm reduction centres has benefits beyond HCV cure but is hampered by high reinfection rates. JHEP Rep 2022; 4:100580. [PMID: 36316992 PMCID: PMC9617206 DOI: 10.1016/j.jhepr.2022.100580] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 08/30/2022] [Accepted: 09/01/2022] [Indexed: 12/02/2022] Open
Abstract
Background & Aims Significant scale-up of treatment among people who inject drugs (PWID) is crucial to achieve WHO HCV elimination targets. We explored the impact of on-site HCV diagnosis and treatment on PWID in an externalised hepatology clinic at the biggest harm reduction centre (HRC) in Barcelona attending to a marginalised PWID population with ongoing high-risk practices. Methods On-site HCV point-of-care testing was performed for diagnosis and treatment delivery. HCV-RNA was assessed at SVR12 (sustained virologic response at 12 weeks) and every 6 months. The programme included behavioural questionnaires at baseline and after treatment. Results Between 2018 and 2020, 919 individuals were prospectively enrolled. Of these, only 46% accepted HCV screening. HCV-RNA+ prevalence was 55.7% (n = 234). Of the 168 (72%) individuals starting treatment, 48% were foreigners, 32% homeless, 73% unemployed, and 62% had a history of incarceration. At enrolment, 70% injected drugs daily and 30% reported sharing needles or paraphernalia. Intention-to-treat SVR12 was 60%; only 4% were virological failures, the remaining were either early reinfections (20%) or losses to follow-up (16%). The overall reinfection rate during follow-up was 31/100 persons/year. HIV coinfection and daily injection were associated with a higher risk of reinfection. Nonetheless, beyond viral clearance, antiviral therapy was associated with a significant reduction in injection frequency, risk practices, and homelessness. Conclusions HCV treatment can be successfully delivered to active PWID with high-risk practices and has a significant benefit beyond HCV elimination. However, approaching this difficult spectrum of the PWID population implies significant barriers such as low rate of screening acceptance and high dropout and reinfection rates. Lay summary People who inject drugs attending harm reduction centres represent the most difficult population to treat for hepatitis C. We show that hepatitis C treatment has a significant benefit beyond viral cure, including improving quality of life, and decreasing injection frequency and risk practices. However, intrinsic barriers and the high reinfection rates hamper the achievement of viral microelimination in this setting. HCV treatment can be successfully delivered to active PWID with high-risk practices. HCV treatment has benefits beyond sustained virological response. PWID reported lower injection frequency and risk practices after engaging in the HCV programme. However, linkage-to-care for PWID attending harm reduction centres is challenging. The high dropout and reinfection rates hamper HCV microelimination in this population.

Treating people where they are: Nurse-led micro-elimination of hepatitis C in supported housing sites for networks of people who inject drugs in Victoria, Canada. Public Health Nurs 2022; 39:1009-1016. [PMID: 35537120 DOI: 10.1111/phn.13092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 04/19/2022] [Accepted: 04/21/2022] [Indexed: 11/28/2022]
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.

Abstract
Hepatitis B and hepatitis C are a global burden and underscore the impact of preventable acute and chronic diseases on personal as well as population level health. Caring for pediatric patients with hepatitis B and C requires a deep understanding of the pathophysiology of viral processes. Insight into the epidemiology, transmission, and surveillance of these infections is critical to prevention and therapy. Extensive research in recent years has created a growing number of treatments, changing the landscape of the medical field's approach to the viral hepatitis pandemic.

Abstract
A prophylactic hepatitis C virus (HCV) vaccine that elicits neutralizing antibodies could be key to HCV eradication. However, the genetic and antigenic properties of HCV envelope (E1E2) proteins capable of inducing anti-HCV broadly neutralizing antibodies (bNAbs) in humans have not been defined. Here, we investigated the development of bNAbs in longitudinal plasma of HCV-infected persons with persistent infection or spontaneous clearance of multiple reinfections. By measuring plasma antibody neutralization of a heterologous virus panel, we found that the breadth and potency of the antibody response increased upon exposure to multiple genetically distinct infections and with longer duration of viremia. Greater genetic divergence between infecting strains was not associated with enhanced neutralizing breadth. Rather, repeated exposure to antigenically related, antibody-sensitive E1E2s was associated with potent bNAb induction. These data reveal that a prime-boost vaccine strategy with genetically distinct, antibody-sensitive viruses is a promising approach to inducing potent bNAbs in humans.

Hepatitis C virus burden: Treating and educating people without prejudice. World J Hepatol 2022; 14:1495-1503. [PMID: 36158919 PMCID: PMC9376782 DOI: 10.4254/wjh.v14.i7.1495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2022] [Revised: 05/26/2022] [Accepted: 06/26/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Hepatitis C virus (HCV) infection has a worldwide incidence of 1.1%. In Italy, 60% of people who inject drugs (PWIDs) and are receiving assistance for substance use disorder are infected with HCV. However, this subset of patients has extremely limited access to care due to multiple factors, including alcohol abuse, psychological comorbidities, and homeless status.
AIM To describe the impact of our HCV-dedicated service for substance use disorder (SSUD) service on PWIDs receiving anti-HCV therapy.
METHODS A dedicated, multidisciplinary team was set up at the SSUD of Trento in October 2020 to provide antiviral treatment to HCV RiboNucleic Acid-positive patients with an active or previous history of substance abuse. The treatment was followed by a health education program. Patients were treated with Direct-Acting Antivirals (DAAs). Data were retrospectively analyzed to assess the efficacy of our dedicated program in terms of therapy completion, HCV eradication, and compliance (primary endpoint). The rate of HCV reinfection and DAA-related toxicity were also assessed (secondary endpoints).
RESULTS A total of 40 patients were enrolled in the study: 28 (70.0%) were treated with Sofosbuvir/Velpatasvir, while 12 (30.0%) received Glecaprevir/Pibrentasvir. At the time of inclusion in the study, 36 patients were receiving opioid agonist maintenance therapy, whilst another 4 had just finished the treatment. 37.5% had a history of alcoholism and 42.5% received concomitant psychiatric treatment. All 40 patients (100.0%) completed the therapy cycle and 92.5% of patients adhered to the program. All patients tested negative for viral load at the end of the treatment. There were no significant drug interactions with common psychiatric treatments and no side effects were observed. The sustained virological response was achieved in 92.5% of cases with good tolerability, although two patients discontinued treatment temporarily. After HCV eradication, one patient died from an overdose, another from complications of cirrhosis, and one reinfection occurred.
CONCLUSION Very high adherence to therapy and good tolerability was observed in our series of HCV patients treated at the SSUD, regardless of the substance abuse condition. Further validation in a larger population is required.

Abstract
Viral hepatitis continues to be a major health concern leading to hepatic decompensation ranging from acute hepatitis to cirrhosis and hepatocellular carcinoma. The hepatic and extrahepatic manifestations are not only debilitating but also associated with a significant economic burden. Over the last two decades, the field of virology has made significant breakthroughs leading to a better understanding of the pathophysiology of viral hepatitis, which in turn has led to new therapeutic options. The advent of direct-acting antiviral agents changed the landscape of hepatitis C virus (HCV) therapy, and new drugs are in the pipeline for chronic hepatitis B virus (HBV) treatment. There has also been a significant emphasis on screening and surveillance programs, widespread availability of vaccines, and linkage of care. Despite these efforts, significant gaps persist in care, and there is a pressing need for increased collaboration and teamwork across the globe to achieve a reduction of disease burden and elimination of HBV and HCV.

Abstract
Since the advent of direct-acting antiviral therapy, the elimination of hepatitis c virus (HCV) as a public health concern is now possible. However, identification of those who remain undiagnosed, and re-engagement of those who are diagnosed but remain untreated, will be essential to achieve this. We examined the extent of HCV infection among individuals undergoing liver function tests (LFT) in primary care. Residual biochemistry samples for 6007 patients, who had venous blood collected in primary care for LFT between July 2016 and January 2017, were tested for HCV antibody. Through data linkage to national and sentinel HCV surveillance databases, we also examined the extent of diagnosed infection, attendance at specialist service and HCV treatment for those found to be HCV positive. Overall HCV antibody prevalence was 4.0% and highest for males (5.0%), those aged 37–50 years (6.2%), and with an ALT result of 70 or greater (7.1%). Of those testing positive, 68.9% had been diagnosed with HCV in the past, 84.9% before the study period. Most (92.5%) of those diagnosed with chronic infection had attended specialist liver services and while 67.7% had ever been treated only 38% had successfully cleared infection. More than half of HCV-positive people required assessment, and potentially treatment, for their HCV infection but were not engaged with services during the study period. LFT in primary care are a key opportunity to diagnose, re-diagnose and re-engage patients with HCV infection and highlight the importance of GPs in efforts to eliminate HCV as a public health concern.

Abstract
BACKGROUND Hepatitis C virus (HCV) treatment through primary care and community-based services will be a critical component of HCV elimination. We evaluated a nurse-coordinated programme providing care across eight sites and analysed progression through the HCV care cascade. METHODS People-accessing services from six primary care clinics, a homeless crisis accommodation provider and a mental health service were directly referred to nurses or engaged by nurses during regular clinic visits. Nurses supported HCV testing, treatment and follow-up. The prescription was provided by affiliated clinicians. Logistic regression was used to examine factors associated with treatment commencement and sustained virological response (SVR) testing. RESULTS Of 640 people referred to and/or engaged by the nurses from January 2017 to July 2019, 518 had an HCV RNA test of whom 381 (74%) were HCV RNA positive. Treatment was commenced by 281 (74%) people of whom 161 had an SVR test, 157 (97.5%) were cured. Opioid agonist therapy was associated with treatment commencement (aOR 2.68, 95% CI 1.48-4.88). People who were homeless/unstably housed were less likely to commence treatment (aOR 0.45, 95% CI 0.23-0.87). Treatment prescription from a specialist (aOR 2.39, 95% CI 1.20-4.74) and recent injection drug use (<6 months) (aOR 2.15, 95% CI 1.07-4.31) was associated with SVR testing. CONCLUSION A nurse-coordinated model of care led to high levels of HCV treatment uptake and cure amongst people attending primary care and community services. More tailored models of care may be beneficial for people who are homeless or have unstable housing. These results support primary care and community-based hepatitis C treatment.

Meet-Test-Treat for HCV management: patients' and clinicians' preferences in hospital and drug addiction services in Italy. BMC Infect Dis 2022; 22:3.

Abstract
Background It has been estimated that the incidence of chronic hepatitis C virus (HCV) will not decline over the next 10 years despite the improved efficacy of antiviral therapy because most patients remain undiagnosed and/or untreated. This study aimed to investigate the opinion of relevant target populations on the practicability, effectiveness and best modalities of the test-and-treat approach in the fight against HCV in Italy. Methods A survey was delivered to patients with HCV from the general population, patients from drug addiction services, hospital physicians and healthcare providers for drug addiction services. Results For both hospital clinicians and SerD HCPs, tolerability is shown as the most important feature of a suitable treatment. Time to treatment (the time from first contact to initiation of treatment) is deemed important to the success of the strategy by all actors. While a tolerable treatment was the main characteristic in a preferred care pathway for general patients, subjects from drug addiction services indicated that a complete Meet–Test–Treat pathway is delivered within the habitual care center as a main preference. This is also important for SerD HCPs who are a strong reference for their patients; hospital clinicians were less aware of the importance of the patient-HCP relationship in this process. Conclusion The health system is bound to implement suitable pathways to facilitate HCV eradication. A Meet–Test–Treat program within the drug addiction services may provide good compliance from subjects mainly concerned with virus transmission.

Abstract
INTRODUCTION Leveraging interpersonal communication among social networks of people who inject drugs (PWID) may be an innovative strategy to increase awareness and access to hepatitis C (HCV) care. However, little is known about HCV communication patterns among PWID and if these patterns vary by gender. METHODS Egocentric network data collected at baseline from HCV-infected PWID enrolled in a randomized HCV treatment intervention trial in Baltimore, Maryland were analyzed. Logistic generalized estimating models were conducted to identify predictors of HCV communication. RESULTS Among 227 PWID, the mean age was 43.8 (SD=10.3), 28.2% (n = 64) were women and 71.8% (n = 163) were men. Female participants reported 516 dyadic relationships and male participants 1139 dyadic relationships. While there were significant gender differences based on socio-demographics, risk behavior and network composition, there were few differences in HCV communication patterns. Both men and women had increased odds of HCV communication with alters who are currently enrolled in drug treatment (AOR 1.7, 95% CI: 1.3-2.4), alters with whom participants share drug preparation equipment (AOR 3.0, 95% CI: 1.9-4.6), alters who are sex partners compared to kin (AOR 3.0; 95% CI: 1.9-4.9) and alters with whom respondents have increased trust (AOR 1.1; 95% CI: 1.11.2) and daily/weekly interactions (AOR 1.7; 95% CI 1.3-2.1). CONCLUSION PWID engaged with trusted alters about HCV disclosure and information, highlighting the important role network interventions could play in this vulnerable population.

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.

Hepatitis C Treatment Among People Who Use Drugs in an Office-Based Opioid Treatment Program Versus a Syringe Exchange Program: A Real-World Prospective Clinical Trial. HEPATITIS MONTHLY 2021.

Abstract
Background: Hepatitis C Virus (HCV) treatment in people who inject drugs (PWID) is a key component of elimination models but PWID face substantial barriers to treatment access. Despite data showing treatment outcomes among PWID on medications for opioid use disorder (MOUD) are similar to non-PWID outcomes, few studies examine PWID treatment outcomes with only syringe services support. Objectives: To evaluate the effect of recruitment for HCV treatment with elbasvir/grazoprevir (E/G) in a syringe services program (SSP) as compared to an MOUD program for people with opioid use disorder. Methods: This real-world, multi-site prospective open-label pilot study compares treatment of PWID with aspartate aminotransferase to platelet ratio (APRI) < 0.7 and genotype 1a, 1b, and 4 HCV with E/G, engaged in MOUD (n = 25) or an SSP (n = 25). The MOUD arm was enrolled through a federally qualified community health center and SSP arm through a nearby SSP. Prospective arms were compared to an academic hepatology clinic group (n = 50). Sustained virologic response at 12 weeks (SVR12), medication adherence, and treatment discontinuation were evaluated. Results: In the MOUD vs SSP arms, substance use throughout treatment was found in 36% (9/25) vs 100% (25/25); good adherence (> 90% pills taken) in 100% (25/25) vs 68% (17/25); treatment completion 100% (25/25) vs 64% (16/25); and SVR12 rates were 96% (24/25) vs 60% (15/25). In the community standard comparison group, SVR12 was achieved in 94% (47/50). There were two virologic failures or re-infections in the SSP group; all other non-responders were due to missing SVR12 data. Conclusions: While recruitment and follow-up are challenging in SSPs, preliminary data suggests adherence, treatment completion, and SVR12 are high in PWID treated with E/G engaging in SSP or MOUD. All metrics are comparable to community standards for non-PWID for treatment of HCV with direct-antiviral drugs.

Seaman A, King CA, Kaser T, Geduldig A, Ronan W, Cook R, Chan B, Levander XA, Priest KC, Korthuis PT. A hepatitis C elimination model in healthcare for the homeless organization: A novel reflexive laboratory algorithm and equity assessment. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 96:103359. [PMID: 34325969 PMCID: PMC8720290 DOI: 10.1016/j.drugpo.2021.103359] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Revised: 06/16/2021] [Accepted: 06/18/2021] [Indexed: 12/13/2022]
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.

The risk of hepatitis C virus recurrence in hepatitis C virus-infected patients treated with direct-acting antivirals after achieving a sustained virological response: A comprehensive analysis. Liver Int 2021; 41:2341-2357. [PMID: 34051040 PMCID: PMC8455436 DOI: 10.1111/liv.14976] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 01/03/2021] [Accepted: 05/25/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND & AIMS The risk for hepatitis C virus (HCV) recurrence persists after HCV eradication with direct-acting antivirals (DAAs), particularly in patients with ongoing high-risk behaviours. Our aim was to assess the risk of HCV recurrence (late relapse and/or reinfection) post-sustained virological response (SVR). METHODS We searched the literature for studies reporting HCV recurrence rates post-SVR in PubMed, Web of Science and the Cochrane Library. Identified publications were divided into groups based on patient risk for HCV reinfection: low-risk HCV mono-infection, high-risk HCV mono-infection and a human immunodeficiency virus (HIV)/HCV coinfection. The HCV recurrence rate for each study was calculated by using events divided by the person-years of follow-up (PYFU). HCV recurrence was defined as confirmed, detectable HCV RNA post-SVR. RESULTS In the 16 studies of low-risk patients, the pooled recurrence rate was 0.89/1000 PYFU (95% confidence interval [CI], 0.16-2.03). For the 19 studies of high-risk patients, the pooled recurrence rate was 29.37/1000 PYFU (95% CI, 15.54-46.91). For the eight studies of HIV/HCV-coinfected patients, the pooled recurrence rate was 23.25/1000 PYFU (95% CI, 4.24-53.39). The higher pooled estimates of recurrence in the high-risk and HIV/HCV-coinfected populations were predominantly driven by an increase in reinfection rather than late relapse. CONCLUSIONS The HCV recurrence risk after achieving SVR with all-oral DAAs therapy is low, and the risk of HCV recurrence in high-risk and HIV/HCV-coinfected populations was driven by an increase in reinfection rather than late relapse.

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
BACKGROUND AND AIM On-going risk-exposure followed by reinfection may jeopardize hepatitis C elimination efforts among people who use drugs. We estimated the HCV reinfection incidence in patients who successfully completed HCV therapy and attended a low-threshold access centre for comprehensive addiction medicine. METHODS Retrospective chart review was undertaken, in a convenience sample of patients with opioid/cocaine use disorders who achieved sustained viral response (SVR) after direct-acting antiviral (DAA) therapy in Zurich, Switzerland between April 2015 and July 2019 (n = 153). HCV reinfection incidence in patients with and without on-going drug use was calculated. RESULTS 79% of the patients were in opioid agonist treatment, and 19% were being managed for other medical or psychiatric conditions. 58% used drugs after SVR, of whom 49% injected. The follow-up period totalled 346 (median 2.1) person-years (py). Overall HCV reinfection incidence was 1.2 (CI-95: 0.3 to 3.0) per 100 py and 1.6 (0.2 to 5.8) in patients with drug use after SVR. CONCLUSION The risk of HCV reinfection after DAA therapy in persons who use drugs can be low if, after SVR, patients remain in care in a well developed comprehensive harm reduction setting.

Detection of active hepatitis C in a single visit and linkage to care among marginalized people using a mobile unit in Madrid, Spain. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 96:103424.

Abstract
BACKGROUND The burden of hepatitis C virus (HCV) infection among marginalized people in Spain is high, despite the fact that HCV prevalence has decreased in recent years. We aimed to assess the effectiveness of a simplified point-of-care (PoC) model for screening for active HCV infection via a mobile unit and subsequent linkage to care with the assistance of navigators. METHODS We carried out a prospective study on 2001 participants from Madrid, Spain. A nurse and a navigator/educator screened for hepatitis C in a mobile unit, using the OraQuick HCV Rapid Antibody Test and Xpert HCV VL Fingerstick assay. Participants with active HCV were referred to the hospital the same day with a navigator for evaluation and treatment of HCV. RESULTS Overall, 1621 (81%) participants had not been exposed to HCV, 380 (18.9%) were positive for HCV antibodies, and 136 (6.8%) had active hepatitis C. Among the latter, 134 (98.5%) received the HCV screening results, 133 (97.8%) had an appointment at the hospital, 126 (92.8%) were seen by a physician once they were at the hospital, and 105 (77.2%) started HCV treatment. Being over 50 years old and a person who uses drugs, particularly people who inject drugs (PWID), was directly associated with active hepatitis C (p<0.05). PWID were the only patients with HCV reinfection (4.3% in people without recent injecting drug use and 5.9% in people with recent injecting drug use). Among PWID, no income and daily alcohol intake were also directly associated with active hepatitis C. People with recent injecting drug use showed the lowest rates of attendance at the hospital (91.8%) and starting HCV treatment (70.4%). CONCLUSION HCV screening using a two-step PoC-based strategy and its linkage to care was extremely efficient for identifying and treating marginalized people with active hepatitis C, thanks to the use of a mobile unit with personnel and technical equipment, an interdisciplinary team, and collaboration between institutions.

Abstract
BACKGROUND We describe the initial results of an adult academic emergency department (ED) nontargeted hepatitis C virus (HCV) screening program serving Appalachia, which is disproportionately affected by the opioid epidemic. METHODS The study was a retrospective screening study of ED systematic, nontargeted, opt-out HCV testing outcomes from July 2018 through September 2020. Eligibility requirements for "nontargeted" HCV testing included age ≥18 years, verbally able to communicate, receiving bloodwork already as part of routine clinical care, and not opting out of testing. For eligible individuals who did not opt out of testing, an HCV antibody (Ab) test was performed. Reactive Ab tests were confirmed with reflexive HCV RNA testing. The primary study outcome was the characterization of HCV Ab and RNA prevalence. RESULTS There were 75 722 unique adult visitors during the period studied. Of these, 54 931 individuals were verbally engaged regarding testing and did not opt out. A total of 34 848 individuals received HCV Ab testing, with 3665 patients (10.5%) having reactive results. RNA confirmatory testing was reflexively performed in all Ab-positive patients, with 1601 (50.3%) positive. The majority of HCV Ab- and RNA-positive patients were young, born after 1965, and were more likely to be White, male, Medicaid insured, and report a history of injection drug use. CONCLUSIONS ED nontargeted, opt-out testing can identify a high prevalence of HCV infection among adult visitors. HCV infection was disproportionately high among younger, White individuals, likely reflecting the escalating syndemic of opioid injection and HCV transmission in Appalachia.

Abstract
Little is known about the distribution of hepatitis C virus (HCV) genotypes among people who inject drugs (PWID) in North African countries, including Tunisia. This study aims to describe HCV genotypes circulating among Tunisian PWID. A cross-sectional study was conducted, and 128 HCV-positive PWID were recruited between 2018 and 2019 from community-based harm reduction centers. After informed consent, sociodemographic characteristics and risk behavior data were obtained using an interviewer-administrated questionnaire. Blood samples were collected for further serological and molecular testing. Overall, five women and 123 men were included. The median age was 39.5 years. The majority of PWID (56.3%) had less than a secondary level of education, were single (57%), were unemployed (65.6%), were incarcerated at least once (93.0%), and had a history of residency in at least one foreign country (50.8%). During the previous 12 months, 82.0% reported having reused syringes at least once, 43.8% shared syringes at least once, while 56.2% had at least one unprotected sexual relation, and 28.1% had more than two different sexual partners. Tattooing was reported among 60.2%. All positive results for HCV-infection by rapid testing were confirmed by enzyme-linked immunosorbent assay (ELISA). HCV-RNA was detectable in 79.7%. Genotyping showed a predominance of genotype 1 (52%) followed by genotype 3 (34%) and genotype 4 (10%). Four patients (4%) had an intergenotype mixed infection. Subtyping showed the presence of six different HCV subtypes as follows: 1a (53.2%), 1b (6.4%), 3a (33.0%), 4a (3.2%), and 4d (4.3%). This is the first study describing circulating HCV genotypes among PWID in Tunisia. The distribution of HCV genotypes is distinct from the general population with a predominance of subtypes 1a and 3a. These findings can be used to guide national efforts aiming to optimize the access of PWID to relevant HCV prevention and treatment measures including pangenotypic regimens for patients infected with HCV genotype 3.

Achieving Hepatitis C Elimination By Using Person-Centered, Nurse-Led Models of Care: A Discussion of Four International Case Studies. Gastroenterol Nurs 2021; 43:303-309.

Abstract
Nurse-led models of care are an important strategy in the management of patients with chronic disease because of the person-centered approach that allows the needs of the individual to be prioritized and addressed in accessible settings. Hepatitis C is caused by a blood-borne virus that can cause liver disease and liver cancer; it predominantly affects marginalized populations, including people who inject drugs. Since 2013, all oral, direct-acting antiviral regimens have been available to cure hepatitis C. Nurses are well placed to be involved in the delivery of hepatitis C testing and treatment because of their extensive reach within marginalized communities and holistic approach to patient care. Four case studies of nurse-led models of care operating in Australia, Canada, the United Kingdom, and the United States are presented to illustrate the important role nurses have in delivering accessible, person-centered hepatitis C testing and treatment. Each case study demonstrates the success of overcoming barriers to hepatitis C testing and treatment such as geographic isolation, incarceration, social marginalization, and inflexible healthcare systems. Achieving the global target to eliminate hepatitis C by 2030 will require the nursing profession to embrace its role as the first point of contact to the healthcare system for many members of marginalized communities potentially at risk of hepatitis C. Nurses are well placed to reduce barriers and facilitate access to healthcare by scaling up activities focused on hepatitis C testing and treatment.

OBJECTIVES The overall goal of the Kentucky Viral Hepatitis Treatment Study (KeY Treat) is to eliminate hepatitis C transmission from a county in Appalachian Kentucky by removing the barriers to accessing hepatitis C virus (HCV) treatment. METHODS/ANALYSIS KeY Treat is a phase IV, open-label, single-arm clinical trial of sofosbuvir/velpatasvir (SOF/VEL) for the treatment of viraemic HCV infections. Those eligible for KeY Treat are at least 18 years of age, viraemic and are residents of the target county. Pregnant women are not eligible. Rapid HCV RNA screening is used to determine eligibility, and those with a quantifiable viral load (VL) consenting to participate initiate SOF/VEL on the same day. All pharmacologic treatment and related medical care is provided free of charge using a non-specialist provider model. Follow-up visits occur at 2, 6 and 12 weeks during treatment to assess medication adherence (measured via VL and self-report), side effects and engagement in risk behaviours. Post-treatment visits occur at 12 weeks (sustained virologic response (SVR12) visit), 6 months and 12 months post-treatment completion to assess re-infection. A control county has also been identified, and prevalence and incidence of chronic HCV infections will be compared with the target community longitudinally. The primary outcome to assess elimination is SVR12. However, several outcomes will be measured to assess the effectiveness of removing the barriers to HCV treatment, including treatment entry, completion and re-infection. Analyses will be conducted via a generalised linear model framework that can incorporate flexible covariate adjustment and multiple outcome types with a compatible link function. Mathematical modelling will be completed assessing the impact and cost-effectiveness of the intervention. ETHICS AND DISSEMINATION KeY Treat has been approved by the Institutional Review Board at the University of Kentucky. Results from KeY Treat will be presented at conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT03949764.

Stöver H, Tarján A, Horváth G, Montanari L. The state of harm reduction in prisons in 30 European countries with a focus on people who inject drugs and infectious diseases. Harm Reduct J 2021; 18:67. [PMID: 34187471 PMCID: PMC8240363 DOI: 10.1186/s12954-021-00506-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Accepted: 05/24/2021] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND People who inject drugs are often imprisoned, which is associated with increased levels of health risks including overdose and infectious diseases transmission, affecting not only people in prison but also the communities to which they return. This paper aims to give an up-to-date overview on availability, coverage and policy framework of prison-based harm reduction interventions in Europe. METHODS Available data on selected harm reduction responses in prisons were compiled from international standardised data sources and combined with a questionnaire survey among 30 National Focal Points of the European Monitoring Centre for Drugs and Drug Addiction to determine the level of availability, estimated coverage and policy framework of the interventions. RESULTS Information about responses to health harms in prisons is limited and heterogeneous. Cross-country comparability is hampered by diverging national data collection methods. Opioid substitution treatment (OST) is available in 29 countries, but coverage remains low (below 30% of people in need) in half of the responding countries. Needle and syringe programmes, lubricant distribution, counselling on safer injecting and tattooing/piercing are scarcely available. Testing for infectious diseases is offered but mostly upon prison entry, and uptake remains low in about half of the countries. While treatment of infections is mostly available and coverage is high for human immunodeficiency virus (HIV) and tuberculosis, hepatitis B and C treatment are less often provided. Health education as well as condom distribution is usually available, but provision remains low in nearly half of the countries. Post-release linkage to addiction care as well as to treatment of infections is available in a majority of countries, but implementation is often partial. Interventions recommended to be provided upon release, such as OST initiation, take-home naloxone and testing of infections, are rarely provided. While 21 countries address harm reduction in prison in national strategic documents, upon-release interventions appear only in 12. CONCLUSIONS Availability and coverage of harm reduction interventions in European prisons are limited, compared to the community. There is a gap between international recommendations and 'on-paper' availability of interventions and their actual implementation. Scaling up harm reduction in prison and throughcare can achieve important individual and public-health benefits.

Pharmacotherapy Profiles in People with Opioid Use Disorders: Considerations for Relevant Drug-Drug Interactions with Antiviral Treatments for Hepatitis C. Pathogens 2021; 10:pathogens10060648. [PMID: 34073674 PMCID: PMC8225070 DOI: 10.3390/pathogens10060648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 05/11/2021] [Accepted: 05/12/2021] [Indexed: 11/16/2022] Open
Abstract
People who inject drugs (PWID) are often affected by physical and psychological diseases and prone to co-medication. In Germany, about 50% of PWID are on opioid substitution therapy (OST). Comprehensive data on pharmacotherapy in these patients may help to select antiviral therapy against hepatitis C virus (HCV) infections and avoid drug–drug interactions (DDIs). We compared co-medication profiles based on statutory health insurance prescriptions (IQVIA database) of PWID (n = 16,693), OST (n = 95,023) and treated HCV patients (n = 7886). Potential DDIs with the most widely used HCV direct-acting agents (Sofosbuvir/Velpatasvir, Glecaprevir/Pibrentasvir and Elbasvir/Grazoprevir) were evaluated based on the Liverpool DDI database. Co-medication was present in 57% of PWID, 57% of OST, 44% of patients on HCV therapy and 46% in a subgroup receiving OST+HCV therapy (n = 747 of 1613). For all groups, co-medication belonging to ATC-class N (nervous system) was most commonly prescribed (in 75%, 68%, 41% and 62% of patients, respectively). Contraindications (i.e., DDIs precluding HCV therapy) were infrequent (0.4–2.5% of co-medications); potential DDIs with HCV therapies were shown for 13–19% of co-medications, namely for specific substances including some analgesics, antipsychotics, anticoagulants, lipid lowering drugs and steroids. In conclusion, concomitant pharmacotherapy is common and clinically relevant when treating HCV infection in PWID.

J Subst Abuse Treat 2021; 127:108460.

Abstract
Direct acting antiviral (DAA) treatment has made the elimination of hepatitis C virus (HCV) a realisable global public health goal and people who inject drugs are a key target population. This study investigates barriers and enablers to DAA treatment of HCV in general practice settings in Australia, from the patient perspective. Semi-structured interviews were conducted with 28 patients; of these patients, seventeen participants were currently on opioid agonist therapy, and four were currently injecting drugs. Thematic data analysis was undertaken and a personal, provider and systems framework was used to describe the barriers and enablers to DAA treatment. Results suggest a range of initiatives are required to support the uptake of DAA in general practice settings. These include the provision of formalised peer information and support, and increasing the accessibility of blood tests and liver assessment on-site. Further, there remains a need to address stigma and discrimination affecting people who inject drugs in community healthcare settings.

Intern Med J 2021; 50:1053-1058.

Abstract
BACKGROUND The recent implementation of a scheme to provide universal access to direct-acting antiviral (DAA) medication to treat hepatitis C virus (HCV) places Australia in a unique position to reach global HCV elimination goals. To achieve this, increasing the uptake and success of DAA treatment in general practice settings is essential. AIMS To explore current enablers and residual barriers to HCV treatment in general practice settings in the post-interferon era from both general practitioner (GP) and patient perspectives. METHODS Semi-structured interviews with 11 GP and 27 patients were conducted to draw out both challenges and facilitators particularly relevant to DAA uptake and treatment journeys. RESULTS Key enablers for successful treatment identified by this study included peer-led GP support and skill development, utilisation of electronic reminder systems, trusting relationships with patients and engaging with patients' social and family networks. Barriers related to accessible testing facilities and knowledge and confidence with DAA treatment continue to limit GP-led treatment. CONCLUSIONS Despite a universal access scheme, barriers to DAA prescription in general practice settings remain. These include access to fibrosis testing and GP confidence in DAA prescription. Strengthening peer-led GP skill development and utilisation of electronic reminder systems may help GP prioritise HCV treatment. Access to fibrosis testing and pathology services with no out-of-pocket costs to patients, particularly in outer-metropolitan areas, should be urgently addressed.

Abstract
People who inject drugs (PWIDs) are a key population targeted in global efforts to increase HIV and Hepatitis C virus (HCV) diagnosis, linkage to care, and treatment retention. Colombia has experienced a significant increase in the incidence of HIV and HCV attributed to the alarming rise in injection drug use. The primary aim of this study was to identify factors influencing access to HIV and HCV care among PWIDs. Survey domains consisted of (1) sociodemographic characteristics; (2) history of HIV-HCV testing and infection status; (3) the 13-item questionnaire developed by Awad and colleagues to explore barriers to HIV and HCV testing, (4) the Barriers to Medical Care questionnaire; and (5) the Risk Assessment Battery. A total of 171 subjects completed the survey. A high proportion of participants reported past year testing for HIV (87%) and HCV (72.8%). However, most respondents elicited numerous barriers to obtaining information, referrals, and insurance coverage for accessing HIV and/or HCV care. Further studies are needed to identify scalable public health measures to overcome these barriers.
