Abstract
Hepatitis C virus (HCV) is a major medical health burden and the leading cause of chronic liver disease and cancer worldwide. More than 58 million people are chronically infected with HCV, with 1.5 million new infections occurring each year. An effective HCV vaccine is a major public health and medical need as recognized by the World Health Organization. However, due to the high variability of the virus and its ability to escape the immune response, HCV rapidly accumulates mutations, making vaccine development a formidable challenge. An effective vaccine must elicit broadly neutralizing antibodies (bnAbs) in a consistent fashion. After decades of studies from basic research through clinical development, the antigen of choice is considered the E1E2 envelope glycoprotein due to conserved, broadly neutralizing antigenic domains located in the constituent subunits of E1, E2, and the E1E2 heterodimeric complex itself. The challenge has been elicitation of robust humoral and cellular responses leading to broad virus neutralization due to the relatively low immunogenicity of this antigen. In view of this challenge, structure-based vaccine design approaches to stabilize key antigenic domains have been hampered due to the lack of E1E2 atomic-level resolution structures to guide them. Another challenge has been the development of a delivery platform in which a multivalent form of the antigen can be presented in order to elicit a more robust anti-HCV immune response. Recent nanoparticle vaccines are gaining prominence in the field due to their ability to facilitate a controlled multivalent presentation and trafficking to lymph nodes, where they can interact with both the cellular and humoral components of the immune system. This review focuses on recent advances in understanding the E1E2 heterodimeric structure to facilitate a rational design approach and the potential for development of a multivalent nanoparticle-based HCV E1E2 vaccine. Both aspects are considered important in the development of an effective HCV vaccine that can effectively address viral diversity and escape.

Birth cohort-specific consideration in an Emergency Department Hepatitis C Testing Programme: A description of age-related characteristics and outcomes. J Viral Hepat 2024; 31:233-239. [PMID: 38366787 DOI: 10.1111/jvh.13930] [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: 09/08/2023] [Revised: 01/15/2024] [Accepted: 02/10/2024] [Indexed: 02/18/2024]
Abstract
The emergency department (ED) has increasingly become an important public health partner in non-targeted hepatitis C virus (HCV) testing and referral to care efforts. HCV has traditionally been an infection associated with the Baby Boomer generation; however, recent exacerbation of the opioid epidemic has resulted in a growing number of younger cohorts, namely Millennials, also impacted by HCV. Examination of this age-related demographic shift, including subsequent linkage success and linkage barriers, from the perspective of an ED-based testing and linkage programme may have implications for future population and health systems interventions. A retrospective descriptive chart review was performed, inclusive of data from August 2015 through December 2020. We compared the quantity of positive HCV screening antibody (Ab) and confirmatory (RNA) tests and further considered linkage rates and correlative demographics (e.g. gender, race). Patient barriers to HCV care linkage (e.g. substance misuse, lack of health insurance, homelessness) were also evaluated. The data set was disaggregated by birth cohort to include Silent Generation (SG) (1928-45), Baby Boomer (BB) (1946-64), Generation X (Gen X) (1965-80), Millennial (1981-96) and Generation Z (1997-2012). Descriptive statistics and chi-square analysis were performed. Overall, 83,817 patients were tested for HCV (50.6% of eligible); 6187 (7.4%) were HCV Ab positive, and 2665 were HCV RNA positive (3.2%). RNA-positive individuals were more likely to be white (70.4%) and male (67.7%); generational distribution was similar (BB 33.3%, Gen X 32.0% and Millennials 32.7%). Amongst Ab-positive patients, white (45.5%), male (47.2%) and Millennial (49.7%) individuals were most likely to be RNA-positive. Overall, 28.1% of the RNA-positive cohort successfully linked to care; linkage to care rates were significantly higher in older generations (38.1% in BB vs. 17.8% in Millennials) (p < .00001). Over 90% were identified as having at least one linkage to care barrier. Younger generations (Gen X and Millennials) were disproportionately impacted by linkage barriers, including incarceration, lack of health insurance, history of mental health and substance use disorders, as well as history of or active injection drug use (IDU) (p < .00001). Older generations (SG and BB) were more likely to be impacted by competing medical comorbidities (p < .00001). The ED population represents a particularly vulnerable, at-risk cohort with a high prevalence of HCV and linkage to care barriers. While past HCV-specific recommendations and interventions have focused on Baby Boomers, this data suggests that younger generations, including Gen X and Millennials, are increasingly affected by HCV and face disparate social risk and social need factors which impede definitive care linkage and treatment.

Optimal hepatitis C treatment adherence patterns and sustained virologic response among people who inject drugs: The HERO study. J Hepatol 2024; 80:702-713. [PMID: 38242324 DOI: 10.1016/j.jhep.2023.12.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 11/27/2023] [Accepted: 12/20/2023] [Indexed: 01/21/2024]
Abstract
BACKGROUND & AIMS Direct-acting antivirals (DAAs) are highly effective for treating HCV infection even among people who inject drugs (PWID). Yet, little is known about patients' adherence patterns and their association with sustained virologic response (SVR) rates. We aimed to summarize various adherence patterns and determine their associations with SVR. METHODS Electronic blister packs were used to measure daily adherence to once-a-day sofosbuvir/velpatasvir during the 12-week treatment period among active PWIDs. Blister pack data were available for 496 participants who initiated DAAs for whom SVR status was known. Adherence was summarized in multiple patterns, such as total adherent days, consecutive missed days, and early discontinuations. Thresholds for adherence patterns associated with >90% SVR rates were also determined. RESULTS The overall SVR rate was 92.7%, with a median adherence rate of 75%. All adherence patterns indicating greater adherence were significantly associated with achieving SVR. Participant groups with ≥50% (>42/84) adherent days or <26 consecutive missed days achieved an SVR rate of >90%. Greater total adherent days during 9-12 weeks and no early discontinuation were significantly associated with higher SVR rates only in those with <50% adherence. Participants with first month discontinuation and ≥2 weeks of treatment interruption had low SVR rates, 25% and 85%, respectively. However, greater adherent days were significantly associated with SVR (adjusted odds ratio 1.10; 95% CI 1.04-1.16; p <0.001) even among participants with ≥14 consecutive missed days. CONCLUSIONS High SVR rates can be achieved in the PWID population despite suboptimal adherence. Encouraging patients to take as much medication as possible, with <2 weeks consecutive missed days and without early discontinuation, was found to be important for achieving SVR. IMPACT AND IMPLICATIONS People who inject drugs can be cured of HCV in >90% of cases, even with relatively low adherence to direct-acting antivirals, but early discontinuations and long treatment interruptions can significantly reduce the likelihood of achieving cure. Clinicians should encourage people who inject drugs who are living with HCV to adhere daily to direct-acting antivirals as consistently as possible, but if any days are interrupted, to continue and complete treatment. These results from the HERO study are important for patients living with HCV, clinicians, experts writing clinical guidelines, and payers. CLINICAL TRIAL NUMBER NCT02824640.

Abstract
BACKGROUND Virtually all cases of hepatitis C virus (HCV) infection in children in the United States occur through vertical transmission, but it is unknown how many children are infected. Cases of maternal HCV infection have increased in the United States, which may increase the number of children vertically infected with HCV. Infection has long-term consequences for a child's health, but treatment options are now available for children ≥3 years old. Reducing HCV infections in adults could decrease HCV infections in children. METHODS Using a stochastic compartmental model, we forecasted incidence of HCV infections in children in the United States from 2022 through 2027. The model considered vertical transmission to children <13 years old and horizontal transmission among individuals 13-49 years old. We obtained model parameters and initial conditions from the literature and the Centers for Disease Control and Prevention's 2021 Viral Hepatitis Surveillance Report. RESULTS Model simulations assuming direct-acting antiviral treatment for children forecasted that the number of acutely infected children would decrease slightly and the number of chronically infected children would decrease even more. Alone, treatment and early screening in individuals 13-49 years old reduced the number of forecasted cases in children and, together, these policy interventions were even more effective. CONCLUSIONS Based on our simulations, acute and chronic cases of HCV infection are remaining constant or slightly decreasing in the United States. Improving early screening and increasing access to treatment in adults may be an effective strategy for reducing the number of HCV infected children in the United States.

JAMA HEALTH FORUM 2024; 5:e240302. [PMID: 38578628 PMCID: PMC10998155 DOI: 10.1001/jamahealthforum.2024.0302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Accepted: 02/02/2024] [Indexed: 04/06/2024] Open
Abstract
Importance Direct-acting antivirals (DAAs) are safe and highly effective for curing hepatitis C virus (HCV) infection, but their high cost led certain state Medicaid programs to impose coverage restrictions. Since 2015, many of these restrictions have been lifted voluntarily in response to advocacy or because of litigation. Objective To estimate how the prescribing of DAAs to Medicaid patients changed after states eased access restrictions. Design, Setting, and Participants This modified difference-in-differences analysis of 39 state Medicaid programs included Medicaid beneficiaries who were prescribed a DAA from January 1, 2015, to December 31, 2019. DAA coverage restrictions were measured based on a series of cross-sectional assessments performed from 2014 through 2022 by the US National Viral Hepatitis Roundtable and the Center for Health Law and Policy Innovation. Exposure Calendar quarter when states eased or eliminated 3 types of DAA coverage restrictions: limiting treatment to patients with severe liver disease, restricting use among patients with active substance use, and requiring prescriptions to be written by or in consultation with specialists. States with none of these restrictions at baseline were excluded. Main Outcomes and Measures Quarterly number of HCV DAA treatment courses per 100 000 Medicaid beneficiaries. Results Of 39 states, 7 (18%) eliminated coverage restrictions, 25 (64%) eased restrictions, and 7 (18%) maintained the same restrictions from 2015 to 2019. During this period, the average quarterly use of DAAs increased from 669 to 3601 treatment courses per 100 000 Medicaid beneficiaries. After states eased or eliminated restrictions, the use of DAAs increased by 966 (95% CI, 409-1523) treatment courses per 100 000 Medicaid beneficiaries each quarter compared with states that did not ease or eliminate restrictions. Conclusions and Relevance The results of this study suggest that there was greater use of DAAs after states relaxed coverage restrictions related to liver disease severity, sobriety, or prescriber specialty. Further reductions or elimination of these rules may improve access to a highly effective public health intervention for patients with HCV.

Abstract
OBJECTIVES Highly effective direct-acting antiviral medications have made it feasible to achieve elimination of hepatis C virus (HCV), including for people with HIV and HCV coinfection. The Centers for Disease Control and Prevention offers guidance for a laboratory surveillance-based HCV viral clearance cascade, which allows public health departments to track the outcomes of people with HCV based on the following steps: ever infected, virally tested, initial infection, and cured or cleared. We examined the feasibility of this approach among people with HIV and HCV coinfection in Connecticut. METHODS We matched an HIV surveillance database, which included cases from the enhanced HIV/AIDS Reporting System as of December 31, 2019, and the HCV surveillance database, the Connecticut Electronic Disease Surveillance System, to define a cohort of coinfected people. We used HCV laboratory results obtained from January 1, 2016, through August 3, 2020, to determine HCV status. RESULTS Of 1361 people who were ever infected with HCV as of December 31, 2019, 1256 (92.3%) received HCV viral testing, 865 of 1256 people tested (68.9%) were HCV infected, and 336 of 865 infected people (38.8%) were cleared or cured. People who had undetectable HIV viral loads at most recent HIV test (<200 copies/mL) were more likely than those with detectable HIV viral loads to achieve HCV cure (P = .02). CONCLUSIONS A surveillance-based approach that includes data based on the Centers for Disease Control and Prevention HCV viral clearance cascade is feasible to implement, can help track population-level outcomes longitudinally, and can help identify gaps to inform HCV elimination strategies.

Abstract
BACKGROUND AND AIMS The objective of this study was to assess the impact of the COVID-19 pandemic and direct-acting antiviral (DAA) agents on mortality related to chronic liver diseases (CLD). METHODS Age-standardized mortality rates were computed based on CLD as the underlying cause of death (UCOD) and as any mention in death certificates (multiple causes of death-MCOD). Time trends in age-standardized mortality rates were investigated using generalized estimation equation models. Additionally, we conducted age, period, and birth cohort (APC) analyses on CLD-related mortality associated with alcohol and hepatitis C virus (HCV). RESULTS Between 2008 and 2021, among residents in the Veneto region (Northeastern Italy) aged ≥35 years, there were 20 409 deaths based on the UCOD and 30 069 deaths based on MCOD from all CLD. We observed a 4% annual decline in age-standardized MCOD-based mortality throughout 2008-2021, with minor peaks corresponding to COVID-19 epidemic waves. Starting in 2016, the decline in HCV-related mortality accelerated further (p < .001). A peak in HCV-related mortality in the 1963-1967 birth cohort was observed, which levelled off by the end of the study period. Mortality related to alcoholic liver disease declined at a slower pace, becoming the most common aetiology mentioned in death certificates. CONCLUSIONS The study demonstrates a significant decrease in HCV-related mortality at the population level in Italy with the introduction of DAAs. Continuous monitoring of MCOD data is warranted to determine if this favourable trend will continue. Further studies utilizing additional health records are needed to clarify the role of other CLD etiologies.

Abstract
BACKGROUND Hospitalization burden related to hepatitis C virus (HCV) infection is substantial. We sought to describe temporal trends in hospitalization rates before and after release of direct-acting antiviral (DAA) agents. METHODS We analyzed 2000-2019 data from adults aged ≥18 years in the National Inpatient Sample. Hospitalizations were HCV-related if (1) hepatitis C was the primary diagnosis, or (2) hepatitis C was any secondary diagnosis with a liver-related primary diagnosis. We analyzed characteristics of HCV-related hospitalizations nationally and examined trends in age-adjusted hospitalization rates. RESULTS During 2000-2019, there were an estimated 1 286 397 HCV-related hospitalizations in the United States. The annual age-adjusted hospitalization rate was lowest in 2019 (18.7/100 000 population) and highest in 2012 (29.6/100 000 population). Most hospitalizations occurred among persons aged 45-64 years (71.8%), males (67.1%), White non-Hispanic persons (60.5%), and Medicaid/Medicare recipients (64.0%). The national age-adjusted hospitalization rate increased during 2000-2003 (annual percentage change [APC], 9.4%; P < .001) and 2003-2013 (APC, 1.8%; P < .001) before decreasing during 2013-2019 (APC, -7.6%; P < .001). Comparing 2000 to 2019, the largest increases in hospitalization rates occurred among persons aged 55-64 years (132.9%), Medicaid recipients (41.6%), and Black non-Hispanic persons (22.3%). CONCLUSIONS Although multiple factors likely contributed, overall HCV-related hospitalization rates declined steadily after 2013, coinciding with the release of DAAs. However, the declines were not observed equally among age, race/ethnicity, or insurance categories. Expanded access to DAA treatment is needed, particularly among Medicaid and Medicare recipients, to reduce disparities and morbidity and eliminate hepatitis C as a public health threat.

Abstract
Importance In the US, the prevalence of hepatitis C virus (HCV) is 1.8% among people who are Black and 0.8% among people who are not Black. Mortality rates due to HCV are 5.01/100 000 among people who are Black and 2.98/100 000 among people who are White. Observations While people of all races and ethnicities experienced increased rates of incident HCV between 2015 and 2021, Black individuals experienced the largest percentage increase of 0.3 to 1.4/100 000 (367%) compared with 1.8 to 2.7/100 000 among American Indian/Alaska Native (50%), 0.3 to 0.9/100 000 among Hispanic (200%), and 0.9 to 1.6/100 000 among White (78%) populations. Among 47 687 persons diagnosed with HCV in 2019-2020, including 37 877 (79%) covered by Medicaid (7666 Black and 24 374 White individuals), 23.5% of Black people and 23.7% of White people with Medicaid insurance initiated HCV treatment. Strategies to increase HCV screening include electronic health record prompts for universal HCV screening, which increased screening tests from 2052/month to 4169/month in an outpatient setting. Awareness of HCV status can be increased through point-of-care testing in community-based settings, which was associated with increased likelihood of receiving HCV test results compared with referral for testing off-site (69% on-site vs 19% off-site, P < .001). Access to HCV care can be facilitated by patient navigation, in which an individual is assigned to work with a patient to help them access care and treatments; this was associated with greater likelihood of HCV care access (odds ratio, 3.7 [95% CI, 2.9-4.8]) and treatment initiation within 6 months (odds ratio, 3.2 [95% CI, 2.3-4.2]) in a public health system providing health care to individuals regardless of their insurance status or ability to pay compared with usual care. Eliminating Medicaid's HCV treatment restrictions, including removal of a requirement for advanced fibrosis or a specialist prescriber, was associated with increased treatment rates from 2.4 persons per month to 72.3 persons per month in a retrospective study of 10 336 adults with HCV with no significant difference by race (526/1388 [37.8%] for Black vs 2706/8277 [32.6%] for White patients; adjusted odds ratio, 1.02 [95% CI, 0.8-1.3]). Conclusions and Relevance In the US, the prevalence of HCV is higher in people who are Black than in people who are not Black. Point-of-care HCV tests, patient navigation, electronic health record prompts, and unrestricted access to HCV treatment in community-based settings have potential to increase diagnosis and treatment of HCV and improve outcomes in people who are Black.

Abstract
The elimination of hepatitis C is a national priority (https://www.hhs.gov/sites/default/files/Viral-Hepatitis-National-Strategic-Plan-2021-2025.pdf). During 2010-2021, hepatitis C virus (HCV) acute and chronic infections (hereinafter referred to as HCV infections) increased in the United States, consequences of which include cirrhosis, liver cancer, and death. Rates of acute infections more than tripled among reproductive-aged persons during this time (from 0.8 to 2.5 per 100,000 population among persons aged 20-29 years and from 0.6 to 3.5 among persons aged 30-39 years). Because acute HCV infection can lead to chronic infection, this has resulted in increasing rates of HCV infections during pregnancy. Approximately 6%-7% of perinatally exposed (i.e., exposed during pregnancy or delivery) infants and children will acquire HCV infection. Curative direct-acting antiviral therapy is approved by the Food and Drug Administration for persons aged ≥3 years. However, many perinatally infected children are not tested or linked to care. In 2020, because of continued increases in HCV infections in the United States, CDC released universal screening recommendations for adults, which included recommendations for screening for pregnant persons during each pregnancy (Schillie S, Wester C, Osborne M, Wesolowski L, Ryerson AB. CDC recommendations for hepatitis C screening among adults-United States, 2020. MMWR Recomm Rep 2020;69[No. RR-2]:1-17). This report introduces four new CDC recommendations: 1) HCV testing of all perinatally exposed infants with a nucleic acid test (NAT) for detection of HCV RNA at age 2-6 months; 2) consultation with a health care provider with expertise in pediatric hepatitis C management for all infants and children with detectable HCV RNA; 3) perinatally exposed infants and children with an undetectable HCV RNA result at or after age 2 months do not require further follow-up unless clinically warranted; and 4) a NAT for HCV RNA is recommended for perinatally exposed infants and children aged 7-17 months who previously have not been tested, and a hepatitis C virus antibody (anti-HCV) test followed by a reflex NAT for HCV RNA (when anti-HCV is reactive) is recommended for perinatally exposed children aged ≥18 months who previously have not been tested. Proper identification of perinatally infected children, referral to care, and curative treatment are critical to achieving the goal of hepatitis C elimination.

Abstract
Immune correlates of hepatitis C virus (HCV) clearance and control remain poorly defined due to the lack of an informative animal model. We recently described acute and chronic rodent HCV-like virus (RHV) infections in lab mice. Here, we developed MHC class I and class II tetramers to characterize the serial changes in RHV-specific CD8 and CD4 T cells during acute and chronic infection in C57BL/6J mice. RHV infection induced rapid expansion of T cells targeting viral structural and nonstructural proteins. After virus clearance, the virus-specific T cells transitioned from effectors to long-lived liver-resident memory T cells (TRM). The effector and memory CD8 and CD4 T cells primarily produced Th1 cytokines, IFN-γ, TNF-α, and IL-2, upon ex vivo antigen stimulation, and their phenotype and transcriptome differed significantly between the liver and spleen. Rapid clearance of RHV reinfection coincided with the proliferation of virus-specific CD8 TRM cells in the liver. Chronic RHV infection was associated with the exhaustion of CD8 T cells (Tex) and the development of severe liver diseases. Interestingly, the virus-specific CD8 Tex cells continued proliferation in the liver despite the persistent high-titer viremia and retained partial antiviral functions, as evident from their ability to degranulate and produce IFN-γ upon ex vivo antigen stimulation. Thus, RHV infection in mice provides a unique model to study the function and fate of liver-resident T cells during acute and chronic hepatotropic infection.

Abstract
INTRODUCTION The role of the Emergency Department (ED) as a vital constituent in Hepatitis C (HCV) screening has become increasingly evident. A key component of the ED's role in HCV screening is the ability to effectively link HCV-RNA positive patients to definitive, HCV-specific care, to include direct-acting antiviral (DAA) medication with resultant sustained virologic response (SVR). We sought to consider the rate of HCV-specific linkage, DAA initiation, and SVR obtained in HCV patients identified from an ED screening program. METHODS A retrospective chart review was conducted in February of 2022 of all individuals who participated in an opt-out ED-based HCV screening program between January 2018 and December 2019. Data was disaggregated by race, gender, age/birth cohort, insurance status, and achievement of sustained virologic response (SVR). Bivariate analysis using Pearson's chi-square was utilized to compare outcomes based on insurance status, race, sex, and birth cohort. RESULTS Of 66,634 individuals screened for HCV during the study period, 885 (1.33%) patients were RNA-positive. Of those individuals, 121 (13.67%) were linked to HCV-specific care. Of those linked, the majority (66.9%) were male, white (66.1%; 33.1% Black), baby boomers or older (53.7%) and publicly insured (57.9%; private insurance 23.1%, self-pay 19%). Among linked patients, 88 (72.7%) started DAA medication. Mirroring linked demographics, majority were male (64.8%), white (64.8%), baby boomers or older (52.3%), and publicly insured (57.6%). White patients initiated on DAA were more likely to obtain SVR (64.9% versus 41.9% Black; p = .04) and uninsured patients were more likely to obtain SVR (82.4% versus 50.7% insured; p = .02). Bivariate consideration of SVR-patients specifically demonstrates that Black patients tended to be older, with significant overrepresentation of Baby boomers (77.5%) as compared to whites (37.5%; p < .0001). Black patients were also more likely to be publicly insured (82.5%) while white patients were more likely to have private insurance (28.8%) or be uninsured (26.3%) than their Black counterparts (12.5% and 5% respectively; p < .05). CONCLUSION An ED-based HCV screening program can result in successful HCV-specific linkage and care, to include DAA initiation and ultimately, SVR. Among linked patients, specific cohort considerations may demonstrate differences in age and insurance status which may have implications on DAA application and adherence, and therefore, individual ability to achieve SVR.

Abstract
Globally, more than 58 million people are chronically infected with Hepatitis C virus (HCV) with 1.5 million new infections occurring each year. An effective vaccine for HCV is therefore a major unmet medical and public health need. Since HCV rapidly accumulates mutations, vaccines must elicit the production of broadly neutralising antibodies (bnAbs) in a reproducible fashion. Decades of research have generated a number of HCV vaccine candidates. Based on the available data and research through clinical development, a vaccine antigen based on the E1E2 glycoprotein complex appears to be the best choice, but robust induction of humoral and cellular responses leading to virus neutralisation has not yet been achieved. One issue that has arisen in developing an HCV vaccine (and many other vaccines as well) is the platform used for antigen delivery. The majority of viral vaccine trials have employed subunit vaccines. However, subunit vaccines often have limited immunogenicity, as seen for HCV, and thus multiple formats must be examined in order to elicit a robust anti-HCV immune response. Nanoparticle vaccines are gaining prominence in the field due to their ability to facilitate a controlled multivalent presentation and trafficking to lymph nodes, where they can interact with both arms of the immune system. This review discusses the potential for development of a nanoparticle-based HCV E1E2 vaccine, with an emphasis on the potential benefits of such an approach along with the major challenges facing the incorporation of E1E2 into nanoparticulate delivery systems and how those challenges can be addressed.

Abstract
Introduction. Direct-acting antiviral medications have made hepatitis C virus (HCV) cure possible for >95% of persons with chronic HCV infection, including those coinfected with HIV. Achieving strategic HCV elimination targets requires an understanding of system, provider, and patient-level barriers to treatment. We explored such barriers among persons with HIV/HCV coinfection who remained untreated for HCV. Methods. Among four primary care HIV clinics in CT with high rates of HCV cure, 25 patients with HIV/HCV coinfection were eligible (no HCV treatment as of March 31, 2021). We conducted retrospective chart reviews of demographics, clinical practice patterns, patient-specific issues such as housing, transportation, food security, and presence of mental health and substance use problems. Results. Among untreated patients, 13 (51%) were female; 17 (68%) were Black; median age was 62 years old. The majority (84%) had injecting drug use (IDU) as HIV transmission risk factor; 14 (56%) were prescribed medication-assisted treatment. Median time since HIV and HCV diagnosis was 25 and 19 years, respectively. Clinic-level barriers were noted in 19 (76%) and included lack of evaluation, treatment not recommended or implemented. Concomitant structural barriers included unstable housing for 11 (44%) and lack of transportation for eight (32%). Most patients had history of illicit substance use (84%) and mental health issues (68%). Many (76%) had multiple potential barriers. Conclusions. Multiple overlapping barriers spanning clinic and patient level domains including social determinants of health were the norm in persons with long-standing HIV/HCV coinfection who have not received HCV treatment. Interventions will require innovative, multi-disciplinary and personalized approaches.

Abstract
Prepandemic time trends in mortality from chronic liver disease (CLD) differed according to specific cause of death (decreasing for liver cirrhosis, stable or increasing for liver cancer), etiology (increasing for nonalcoholic fatty liver disease, generally decreasing for other etiologies), and world region (decreasing in areas with the highest burden of hepatitis B virus, increasing in Eastern Europe and other countries). The coronavirus disease 2019 (COVID-19) pandemic affected mortality of patients with CLD both directly, with a higher risk for severe illness and death depending on age, stage and etiology of the disease, and indirectly, through social isolation and loss of support, harmful drinking, and difficulties in access to care. Nevertheless, only sparse data are available on variations in CLD as a cause of death during the pandemic. In the USA, in 2020-2021 a growth in mortality was registered for all liver diseases, more marked for alcoholic liver disease, especially among young people aged 25-44 years and in selected ethnic groups. COVID-19 related deaths accounted only for a minor part of the excess. Further data from mortality registers of other countries are warranted, preferably adopting the so-called multiple cause-of-death approach, and extended to deaths attributed to viral hepatitis and liver cancer.

Abstract
INTRODUCTION Limited information is available on trends in hepatitis C virus (HCV) infection, particularly in Central Europe. To address this knowledge gap, we analyzed HCV epidemiology in Poland, considering socio-demographic characteristics, changing patterns over time, and the impact of the COVID-19 pandemic. MATERIAL AND METHODS We examined HCV cases (diagnosis and deaths) reported by national registries and used joinpoint analysis to estimate time trajectories. RESULTS Between 2009 and 2021, there were changes in the trends of HCV, shifting from positive to negative in Poland. Among men, there was a significant increase initially in diagnosis rate of HCV in rural areas (annual percent change, APC2009-2016 +11.50%) and urban areas (APC2009-2016 +11.44%) by 2016. In subsequent years until 2019, the trend changed direction, but the reduction was weak (Ptrend > 0.05) in rural areas (-8.66%) and urban areas (-13.63%). During the COVID-19 pandemic, the diagnosis rate of HCV dramatically decreased in rural areas (APC2019-2021 -41.47%) and urban areas (APC2019-2021 -40.88%). Among women, changes in the diagnosis rate of HCV were less pronounced. In rural areas, there was a significant increase (APC2009-2015 +20.53%) followed by no significant change, whereas changes occurred later in urban areas (APC2017-2021 -33.58%). Trend changes in total mortality due to HCV were mainly among men, with a significant decrease in rural (-17.17%) and urban (-21.55%) areas from 2014/2015. CONCLUSIONS The COVID-19 pandemic reduced HCV diagnosis rates in Poland, especially for diagnosed cases. However, further monitoring of HCV trends is necessary, along with national screening programs and improved linkage to care.

Abstract
Introduction Hepatitis C virus is associated with high morbidity and mortality-chronic liver disease is a leading cause of death among Latinos in the U.S. Screening for hepatitis C virus in community health center settings, which serve a disproportionate percentage of Latinos, is essential to eradicating hepatitis C virus infection. We assessed hepatitis C virus screening disparities in adults served by community health centers by ethnicity and language preference. Methods This was an observational cohort study (spanning 2013-2017) of adults born in 1945-1965 in the Accelerating Data Value Across a National Community Health Center Network electronic health record data set. Our exposure of interest was race/ethnicity and language preference (non-Hispanic White, Latino English preferred, Latino Spanish preferred). Our primary outcome was the relative hazard of hepatitis C virus screening, estimated using multivariate Cox proportional hazards regression. Results A total of 182,002 patients met the study criteria and included 60% non-Hispanic Whites, 29% Latino Spanish preferred, and 11% Latino English preferred. In total, 9% received hepatitis C virus screening, and 2.4% were diagnosed with hepatitis C virus. Latino English-preferred patients had lower rates of screening than both non-Hispanic Whites and Latino Spanish preferred (5.5% vs 9.4% vs 9.6%, respectively). Latino English preferred had lower hazards of hepatitis C virus screening than non-Hispanic Whites (adjusted hazard ratio=0.56, 95% CI=0.44, 0.72), and Latino Spanish preferred had similar hazards of hepatitis C virus screening (adjusted hazard ratio=1.11, 95% CI=0.88, 1.41). Conclusions We found that in a large community health center network, adult Latinos who preferred English had lower hazards of hepatitis C virus screening than non-Hispanic Whites, whereas Latinos who preferred Spanish had hazards of screening similar to those of non-Hispanic Whites. The overall prevalence of hepatitis C virus screening was low. Further work on the role of language preference in hepatitis C virus screening is needed to better equip primary care providers to provide this recommended preventive service in culturally relevant ways.

Abstract
Ongoing sexual transmission presents a significant barrier to viral hepatitis control. Endemic transmission of hepatitis A virus continues through communities of men with male sex partners, despite vaccine availability. Increased incidence of hepatitis B virus from 2014-2018 prompted expanded vaccination guidelines, but uptake and physician awareness remain poor. Hepatitis C virus while strongly associated with injection drug use, is also transmitted by high-risk sexual contact. Despite universal screening recommendations and curative treatment, incidence continues to increase. Even with safe and highly effective vaccinations or treatments, sexual transmission of viral hepatitides must be addressed to achieve disease elimination.

Abstract
Using organs from donors with treatable infections is a strategy to increase the quality and number of organs for transplantation. For HIV, pilot studies of kidney and liver transplantation from donors with HIV to recipients with HIV demonstrate excellent early outcomes. However, the number of donors and transplants per year remains lower than projected due to several barriers. For HCV, the use of organs from donors with HCV has expanded to recipients without HCV due to safe, effective direct-acting antivirals for HCV, which are well-tolerated in transplant recipients. Studies across organ types demonstrate good outcomes and shorter wait times.

Abstract
BACKGROUND Persons who inject drugs (PWID) are a key population for hepatitis C virus (HCV) treatment. Study aims were to describe injection practices of PWID during HCV treatment with direct-acting antivirals (DAAs) and assess whether injection practices were associated with not achieving a sustained virologic response (SVR). METHODS Secondary analysis of the HERO Study (ClinicalTrials.gov, NCT02824640), a pragmatic randomized trial in 8 U.S. states to evaluate the effectiveness of HCV care models among active PWID seen in opioid treatment programs and community clinics. Frequency, sharing and reuse of injecting equipment were assessed at baseline, end-of-treatment (EOT) and quarterly visits up to 60 weeks post-treatment. Generalized Estimating Equations logistic regression models with linear spline were used to compare trends in injecting behaviors during vs. post-treatment. Multivariable logistic regression models explored associations between injecting behaviors during treatment and lack of SVR. RESULTS Among 501 participants, 27% were female, 35% were non-white, mean age was 44 (SD 11.5) years and nearly half (49%) were unhoused. At baseline, 41% reported receptive sharing of injecting equipment, declining to 16% at EOT visit. Receptive sharing of cookers, rinses, or needles/syringes during treatment was associated with a nearly 5-fold increase in not achieving SVR (adjusted odds ratio (aOR)=4.83; 95% CI: 2.26, 10.28) as was reuse of one's own needles/syringes (aOR=2.37; 95% CI: 1.11, 4.92). CONCLUSIONS PWID in the HERO study adopted safer injecting behaviors during DAA treatment; receptive sharing of injecting equipment and reuse of one's own equipment during treatment were associated with not achieving cure.

Abstract
BackgroundDigestive diseases are very common worldwide and account for considerable health care use and expenditures. However, there are no global population-based estimates of the disease burden and temporal trend of digestive diseases.MethodsAnnual case numbers, age-standardized rates of prevalence, incidence, death, and disability-adjusted life-years (DALYs), and their estimated annual percentage changes (EAPCs) for digestive diseases between 1990 and 2019 were derived from the Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2019. The association between digestive disease burden and the sociodemographic index (SDI) was investigated. We also calculated DALYs attributable to risk factors that had evidence of causation with digestive diseases.ResultsGlobally, in 2019, there were 88.99 million DALYs due to digestive diseases (3.51% of global DALYs). Digestive diseases were the 13th leading cause of DALYs globally in 2019. Global digestive disease DALYs were highest in the middle SDI quintile and in South Asia and were higher in males than females in 2019. Cirrhosis and other chronic liver diseases constituted the highest proportion of categorized digestive disease DALY burdens globally. From 1990 to 2019, the global age-standardized DALY rate of digestive diseases decreased from 1570.35 in 1990 to 1096.99 in 2019 per 1,00,000 population, with the EAPC being −1.32 (95% confidence interval [CI] −1.36 to −1.27). In 2019, the largest contributor to digestive disease DALYs at the global level, for both sexes, was alcohol use.ConclusionThe results of this systematic analysis suggest that the global burden of digestive diseases is substantial and varies markedly according to age, sex, SDI, and geographical region. These results provide comprehensive and comparable estimates that can potentially inform efforts toward digestive disease control worldwide.

Abstract
Syringe services programs (SSPs) are evidence-based programs. SSPs are integral in preventing bloodborne diseases while increasing access to care and reducing drug overdose deaths. SSPs are often the only source of health care for people who use drugs. Several states in the United States support and offer community-based SPPs; however, US prisons do not offer such programs to those incarcerated. Nurses are bridging the gap in support of SSPs and are being backed by organizations such as the American Nurses Association and the Association of Nurses in AIDS Care.

Abstract
PURPOSE American Indians/Alaska Native (AI/AN) persons are disproportionately affected by hepatitis C virus (HCV). The Northwest Portland Area Indian Health Board Indian Country Extension for Community Healthcare Outcomes (ECHO) telehealth clinic supports primary care providers (PCPs) in treating HCV. We evaluated the extent to which Indian Country ECHO increases access to HCV treatment and holistically serves AI/AN patients. METHODS We conducted a retrospective descriptive analysis of Indian Country ECHO treatment recommendations from 2017 to 2021. Recommendations were classified into the following categories: HCV treatment with direct-acting antiviral medication, prevention, substance use disorder treatment, lab or imaging orders, pharmacological considerations, behavior changes, other, and referral. Subanalysis of treatment recommendations was completed for patients with cirrhosis. FINDINGS Of the 776 patients from 77 Indian Health System facilities who presented at Indian Country ECHO, 718 (93%) received treatment recommendations. Most patients (93%) received recommendations for HCV treatment by their PCP; only 3% received a recommendation for referral to a hepatologist or liver transplant center for additional care. Most patients received at least 1 recommendation beyond the scope of HCV treatment provision. Cirrhosis criteria were met by 8% of patients, of which 80% received recommendations for HCV treatment by their PCP and 25% received recommendations for referral to a specialist for additional care. CONCLUSIONS Most patients presented at the Indian Country ECHO received recommendations for HCV treatment by their PCP, along with recommendations beyond the scope of HCV. Indian Country ECHO telehealth clinic provides comprehensive recommendations to effectively integrate evidence-based HCV treatment with holistic care at the primary care level.

Abstract
OBJECTIVES Nearly 1 in 3 people with hepatitis C virus (HCV) infection pass through the criminal justice system annually; the system is a crucial location for HCV screening, education, and linkage to care. We aimed to (1) determine the prevalence and incidence of HCV antibody positivity and (2) evaluate the demographic characteristics of people with HCV in a large urban jail. METHODS We offered universal opt-out HCV testing to any person undergoing a routine blood test at the Dallas County Jail from June 2015 through December 2019 (N = 14 490). We extracted data on demographic characteristics from the electronic medical record and collected data on risk factors from people with HCV antibody positivity. We performed univariate and multivariate analyses. RESULTS The prevalence of HCV antibody positivity was 16.7%; the incidence was 13.5 cases per 1000 person-years. HCV antibody positivity was significantly associated with older age (P < .001), female sex (P = .004), non-Hispanic White race versus non-Hispanic Black race (P < .001), and being released to prison versus not (P < .001). Among people born after 1965, those who were HCV antibody-positive were more frequently non-Hispanic White and Hispanic women, whereas among those born in 1965 or before, those who were HCV antibody-positive were more frequently non-Hispanic Black men. CONCLUSIONS The high prevalence and incidence of HCV antibody positivity in a large county jail argue for routine, universal HCV testing and prevention counseling in criminal justice settings. Changing demographic characteristics mirror those of the national injection drug use epidemic and shed insight into designing interventions for risk reduction, education, linkage to care, and treatment.

Abstract
There is a significant number of Emergency Department (ED) patients with known chronic hepatitis C virus (HCV) infection who have not been treated with directly acting antivirals. We implemented a pilot ED-based linkage-to-care program to address this need and evaluated the impact of the program using the HCV Care Continuum metrics. Between March 2015 and May 2016, dedicated patient care navigators identified HCV RNA-positive patients in an urban ED and offered expedited appointments with the on-site viral hepatitis clinic. Patient demographics and care continuum outcomes were abstracted from the EMR and analysed to determine significant factors influencing linkage-to-care (LTC) and treatment initiation rates. The ED linkage-to-care program achieved a 43% linkage-to-care rate (165/384), 22% treatment rate (84/384) and 16% sustained virologic response rate (63/384). Significant associations were found between linkage-to-care and increasing age (OR = 1.03), Medicare insurance (OR = 2.21) and having a primary care physician (PCP) (OR = 4.03). For patients who were linked, the odds of initiating treatment were also positively significantly associated with increasing age (OR = 1.04) and having a PCP (OR = 2.77). For patients who initiated treatment, the odds of sustained virologic response were marginally associated with having a PCP (OR = 4.92).Our ED linkage-to-care program utilized care coordination to successfully link nearly half of approached HCV RNA-positive patients to care. This design can be feasibly replicated by other EDs given limited non-clinical training required for linkage-to-care staff. Adoption of similar programs in other EDs may improve the rates of LTC and treatment initiation for previously diagnosed HCV patients.

Abstract
BACKGROUND Hepatitis C (HCV) poses a major public health problem in the USA. While early identification is a critical priority, subsequent linkage to a treatment specialist is a crucial step that bridges diagnosed patients to treatment, cure, and prevention of ongoing transmission. Emergency departments (EDs) serve as an important clinical setting for HCV screening, although optimal methods of linkage-to-care for HCV-diagnosed individuals remain unknown. In this article, we describe the rationale and design of The Determining Effective Testing in Emergency Departments and Care Coordination on Treatment Outcomes (DETECT) for Hepatitis C (Hep C) Linkage-to-Care Trial. METHODS The DETECT Hep C Linkage-to-Care Trial will be a single-center prospective comparative effectiveness randomized two-arm parallel-group superiority trial to test the effectiveness of linkage navigation and clinician referral among ED patients identified with untreated HCV with a primary hypothesis that linkage navigation plus clinician referral is superior to clinician referral alone when using treatment initiation as the primary outcome. Participants will be enrolled in the ED at Denver Health Medical Center (Denver, CO), an urban, safety-net hospital with approximately 75,000 annual adult ED visits. This trial was designed to enroll a maximum of 280 HCV RNA-positive participants with one planned interim analysis based on methods by O'Brien and Fleming. This trial will further inform the evaluation of cost effectiveness, disparities, and social determinants of health in linkage-to-care, treatment, and disease progression. DISCUSSION When complete, the DETECT Hep C Linkage-to-Care Trial will significantly inform how best to perform linkage-to-care among ED patients identified with HCV.

Perceptions Towards HCV Treatment with Direct Acting Antivirals (DAAs): A Qualitative Analysis with Persons with HIV/HCV Co-infection Who Delay or Refuse Treatment. AIDS Behav 2023; 27:119-133.

Abstract
In the United States, approximately 25% of people with HIV (PWH) are co-infected with hepatitis C (HCV). Since 2014, highly effective and well-tolerated direct-acting antivirals (DAAs) have revolutionized HCV treatment. Uptake of DAAs by people with HIV/HCV co-infection has improved but remains suboptimal due to system, provider, and patient-level barriers. To explore patient-level issues by better understanding their attitudes towards DAA treatment, we conducted qualitative interviews with 21 persons with HIV/HCV co-infection who did not consent to DAA treatment or delayed treatment for at least 1 year after diagnosis. We found PWH perceived DAA treatment barriers and facilitators on multiple levels of the social-ecological environment: the individual (HCV disease and treatment literacy), interpersonal (peer influence), institutional (media and healthcare provider relationship), and structural levels (treatment cost and adherence support). Recommendations to improve DAA treatment uptake include HCV-treatment adherence support, HCV disease and treatment literacy training (particularly for substance use and DAA treatment interactions), and encouraging PWH who have successfully completed DAA treatment to speak with their peers.

Abstract
Due to the high prevalence of Hepatitis C virus (HCV) infection among individuals born between 1945 and 1965, in 2012 the Centers for Disease Control and Prevention began recommending HCV screening for this birth cohort. As adherence to HCV treatment is essential for sustained virologic response, identifying factors influencing medication adherence is important. The validated Adherence to Refills and Medications Scale (ARMS) is used to study recent medication adherence in those with chronic disease. This cross-sectional pilot study assesses factors associated with reduced adherence, indicated by higher ARMS scores, among individuals in this birth cohort. To elucidate factors associated with medication adherence, measured by the ARMS score, among a birth cohort at higher risk for HCV to guide future treatment and improve adherence. Patients born between 1945 and 1965, accessing care at an academic family medicine clinic, were recruited between April and June 2019. Demographics, prior HCV diagnosis, HCV risk factors (prior imprisonment, tattoos, and intravenous drug use), depression assessment (Patient Health Questionnaire-9), adverse childhood experiences (ACEs), and ARMS scores were collected. Mean ARMS scores were compared using t tests and analysis of variance (α = 0.05), while multiple variable models were performed using linear regression. Women comprised 58% of participants (n = 76), 52% reported depression and 37% 4 or more ACEs. The mean ARMS score was 16.3 (SD = 3.43) and 10% reported prior diagnosis of HCV. In the final multiple variable model, ARMS scores were 2.3 points higher in those with mild depression (95% CI: 0.63, 4.04), 2.0 in those with at least 4 ACEs (95% CI: 0.55, 3.49), and 1.8 in those with tattoos (95% CI: 0.30, 3.28). ACEs and food insecurity were identified as confounding variables in those with moderate to severe depression. This study found medication adherence was related to depression, ACEs, tattoos, and food insecurity among patients in this birth cohort at higher risk for HCV.

Abstract
OBJECTIVE Approximately 2.4 million people in the United States are living with hepatitis C virus (HCV) infection. The objective of our study was to describe demographic and socioeconomic characteristics, liver disease-related risk factors, and modifiable health behaviors associated with self-reported testing for HCV infection among adults. METHODS Using data on adult respondents aged ≥18 from the 2013-2017 National Health Interview Survey, we summarized descriptive data on sociodemographic characteristics and liver disease-related risk factors and stratified data by educational attainment. We used weighted logistic regression to examine predictors of HCV testing. RESULTS During the study period, 11.7% (95% CI, 11.5%-12.0%) of adults reported ever being tested for HCV infection. Testing was higher in 2017 than in 2013 (adjusted odds ratio [aOR] = 1.27; 95% CI, 1.18-1.36). Adults with ≥some college were significantly more likely to report being tested (aOR = 1.60; 95% CI, 1.52-1.69) than adults with ≤high school education. Among adults with ≤high school education (but not adults with ≥some college), those who did not have health insurance were less likely than those with private health insurance (aOR = 0.78; 95% CI, 0.68-0.89) to get tested, and non-US-born adults were less likely than US-born adults to get tested (aOR = 0.77; 95% CI, 0.68-0.87). CONCLUSIONS Rates of self-reported HCV testing increased from 2013 to 2017, but testing rates remained low. Demographic characteristics, health behaviors, and liver disease-related risk factors may affect HCV testing rates among adults. HCV testing must increase to achieve hepatitis C elimination targets.

Abstract
Integration of genetic, social network, and spatial data has the potential to improve understanding of transmission dynamics in established HCV epidemics. Sequence data were analyzed from 63 viremic people who inject drugs recruited in the Boston area through chain referral or time-location sampling. HCV subtype 1a was most prevalent (57.1%), followed by subtype 3a (33.9%). The phylogenetic distances between sequences were no shorter comparing individuals within versus across networks, nor by location or time of first injection. Social and spatial networks, while interesting, may be too ephemeral to inform transmission dynamics when the date and location of infection are indeterminate.

Abstract
BACKGROUND Despite constituting the largest segment of the correctional population, individuals on court-ordered probation remain largely unstudied with respect to hepatitis C virus (HCV) testing and linkage-to-care. We conducted a retrospective, descriptive analysis to estimate prevalence of diagnosed HCV and the subsequent HCV care cascade among a cohort of individuals enrolled in an adult probation program over a 25-month period in Denver, Colorado. METHODS We utilized probabilistic matching with first and last name, sex, and birthdate to identify individuals enrolled in probation between July 1, 2016 and July 30, 2018 who had a medical record at the participating safety-net healthcare institution as of December 31, 2019. Electronic medical record data were queried for evidence of HCV testing and care through June 30, 2021. The state HCV registry was also queried for prevalence of reported HCV cases among the cohort. RESULTS This cohort included 8,903 individuals; 6,920 (78%) individuals had a medical record at the participating institution, and of these, 1,037 (15%) had ever been tested for HCV (Ab or RNA) and 308 (4% of those with a medical record, 30% of those tested) had detectable HCV RNA. Of these, 105 (34%) initiated HCV treatment, 89 (29%) had a subsequent undetectable HCV viral load, and 65 (21%) had documentation of HCV cure. Eleven percent of the total cohort had records of positive HCV Ab or RNA tests in the state HCV registry. CONCLUSIONS This study demonstrates the importance of HCV screening and linkage-to-care for individuals enrolled in probation programs. A focus on this population could enhance progress towards HCV elimination goals.

Abstract
Until the COVID-19 pandemic, San Francisco's hepatitis C virus (HCV) elimination initiative, End Hep C SF, was expanding and refining HCV testing and treatment strategies citywide, making progress toward local HCV elimination goals. Although a shelter-in-place health order issued in March 2020 categorized HCV testing as an "essential service," most HCV testing and treatment immediately stopped until COVID-19-safe protocols could be implemented. During the 14 months of pandemic-related organizational closures, End Hep C SF transitioned to a 100% virtual model, maintaining regularly scheduled meetings. Community-based HCV antibody testing decreased 80% from February to April 2020, and HCV treatment initiation also decreased, although both services started to rebound in mid-to-late 2020, partially as a result of End Hep C SF collaborations. End Hep C SF service providers, clinicians, and advocates reported that the continuous communication and common agenda of End Hep C SF-2 principles of the collective impact initiative-served as a familiar touchpoint and helpful source of information during this isolating and uncertain time. Ultimately, End Hep C SF allowed us to continue HCV elimination strategies through 6 lessons learned: maintaining HCV treatment access through telehealth and mobile services; leveraging research studies that provided HCV testing and treatment; offering HCV screening and linkage to care in tandem with COVID-19-related initiatives; being flexible and inventive, such as administering HCV treatment to residents of shelter-in-place hotels; establishing a data dashboard to track HCV testing and treatment; and relying on partnerships to solve problems and avoid burnout.

Abstract
BACKGROUND AND AIMS High unit prices of treatments limit access. For epidemics like that of hepatitis C virus (HCV), reduced treatment access increases prevalence and incidence, making the infectious disease increasingly difficult to manage. The objective of the current study was to construct and test an alternative pricing model, the Payer License Agreement (PLA), and determine whether it could improve outcomes, cut costs and incentivize innovation versus the current unit-based pricing model. METHODS We built and used computational models of hepatitis C disease progression, treatment, and pricing in historical and future scenarios and quantitatively analyzed their economic and epidemiological impact in three high-income countries. RESULTS This study had three key results regarding HCV treatment. First, if the PLA model had been implemented when interferon-free direct-acting antiviral (DAA) combinations launched, the number of patients treated and cured would have more than doubled in the first three years, while the liver-related deaths (LRDs) would have decreased by around 40%. Second, if the PLA model had been implemented beginning in 2018, the year that several Netflix-like payment models were under implementation, the number of treated and cured patients would nearly double, and the LRDs would decline by more than 55%. Third, implementing the PLA model would result in a decline in total payer costs of more than 25%, with an increase to pharmaceutical manufacturer revenues of 10%. These results were true across the three healthcare landscapes studied, the USA, the UK and Italy, and were robust against variations to critical model parameters through sensitivity analysis. CONCLUSIONS AND RELEVANCE These results suggest that implementation of the PLA model in high-income countries across a variety of health system contexts would improve patient outcomes at lower payer cost with more stable revenue for pharmaceutical manufacturers. Health policy-makers in high-income countries should consider the PLA model for application to more cost-effective management of HCV, and explore its application for other infectious diseases with curative therapies available now or soon.

Abstract
BACKGROUND Hepatitis C (HCV) infection has been rising in the suburban and rural USA, mainly via injection-based transmission. Injection and sexual networks are recognized as an important element in fostering and preventing risky behavior; however, the role of social support networks has received somewhat less attention. METHODS Using baseline data from an ongoing longitudinal study, we examined the composition and structure of injection drug use (IDU), sex, and social support networks of young people who inject drugs (aged 18-30) and their injection network members. Lasso logistic regression was used to select a subset of network characteristics that were potentially important predictors of injection risk behaviors and HCV exposure. RESULTS Several measures of IDU, sexual, and support network structure and composition were found to be associated with HCV exposure, receptive syringe sharing (RSS), and ancillary equipment sharing. Gender and sexual relationships were important factors for all risk behaviors. Support network characteristics were also important, notably including a protective effect of majority Hispanic support networks for RSS and HCV exposure. Both IDU network residence heterogeneity and support network geography were associated with injection equipment sharing. CONCLUSIONS The associations of IDU and support network geography with equipment sharing highlight the need to extend harm reduction efforts beyond urban areas. Greater understanding of support network influences on risk behavior may provide important insights to strengthen the benefits of harm reduction. In considering the probability of HCV transmission, it is important to consider setting and network structures that promote propagation of risk.

Abstract
BACKGROUND Even though substance users have the highest hepatitis C virus (HCV) burden, many lack knowledge about the infection. Lack of knowledge is an important obstacle to pursuing HCV care. Although printed materials are conventionally utilized to disseminate HCV-related knowledge, narrative story-telling videos may be an alternative. Data are extremely limited, however, in the ability of storytelling videos to increase HCV knowledge among substance users. In this study, we hypothesized that a story-telling narrative video would increase substance user’s immediate and 1-month HCV-related knowledge compared to a printed format.
AIM To assess immediate and 1-month HCV-related knowledge retention among substance users comparing education delivered via a storytelling narrative video compared to a printed format.
METHODS We conducted a prospective matched, case-control study among substance users actively prescribed buprenorphine enrolled from two sites. The intervention site received the video and the control site, the brochure. Participants (n = 176) were matched on age, gender, and race. We obtained extensive patient and stakeholder input on the video’s design, validated the video’s content, and developed a recruitment plan to guide participant enrollment. Knowledge was assessed by administration of a 25-item instrument immediately before, immediately after, or one month after the intervention. Data were analyzed using nonparametric and generalized linear mixed-effects models.
RESULTS We recruited a total of 176 substance users, 90 and 86 individuals, from each site, respectively. One-month follow up occurred in 92% and 94% of enrollees in the control and intervention groups, respectively. In comparison with the pre-intervention scores, immediate knowledge recall increased significantly for both the intervention (P < 0.0001) and control (P < 0.0001) groups. Multivariate modeling revealed a significant improvement in HCV-related knowledge and retention (P = 0.033) among participants who viewed the storytelling video.
CONCLUSION Storytelling narratives emphasizing HCV education appear to be an effective method to increase HCV-related knowledge among substance users. They should become an educational cornerstone to promote HCV management among this population.

Abstract
Importance To achieve hepatitis C elimination, treatment programs need to engage, treat, and cure people who inject drugs. Objective To compare a low-threshold, nonstigmatizing hepatitis C treatment program that was colocated at a syringe service program (accessible care) with facilitated referral to local clinicians through a patient navigation program (usual care). Design, Setting, and Participants This single-site randomized clinical trial was conducted at the Lower East Side Harm Reduction Center, a syringe service program in New York, New York, and included 167 participants who were hepatitis C virus RNA-positive and had injected drugs during the prior 90 days. Participants enrolled between July 2017 and March 2020. Data were analyzed after all patients completed 1 year of follow-up (after March 2021). Interventions Participants were randomized 1:1 to the accessible care or usual care arm. Main Outcomes and Measures The primary end point was achieving sustained virologic response within 12 months of enrollment. Results Among the 572 participants screened, 167 (mean [SD] age, 42.0 [10.6] years; 128 (77.6%) male, 36 (21.8%) female, and 1 (0.6) transgender individuals; 8 (4.8%) Black, 97 (58.5%) Hispanic, and 53 (32.1%) White individuals) met eligibility criteria and were enrolled, with 2 excluded postrandomization (n = 165). Baseline characteristics were similar between the 2 arms. In the intention-to-treat analysis, 55 of 82 participants (67.1%) in the accessible care arm and 19 of 83 participants (22.9%) in the usual care arm achieved a sustained virologic response (P < .001). Loss to follow-up (12.2% [accessible care] and 16.9% [usual care]; P = .51) was similar in the 2 arms. Of the participants who received therapy, 55 of 64 (85.9%) and 19 of 22 (86.3%) achieved a sustained virologic response in the accessible care and usual care arms, respectively (P = .96). Significantly more participants in the accessible care arm achieved all steps in the care cascade, with the greatest attrition in the usual care arm seen in referral to hepatitis C virus clinician and attending clinical visit. Conclusions and Relevance In this randomized clinical trial, among people who inject drugs with hepatitis C infection, significantly higher rates of cure were achieved using the accessible care model that focused on low-threshold, colocated, destigmatized, and flexible hepatitis C care compared with facilitated referral. To achieve hepatitis C elimination, expansion of treatment programs that are specifically geared toward engaging people who inject drugs is paramount.

Abstract
BACKGROUND HCV infection rates among U.S. blood donors have been well characterized; however, few studies evaluate HCV genotypes among blood donors. Monitoring trends in disease and demographic patterns contribute to understanding the safety of the blood supply. Here we examined the demographic characteristics and the distribution of HCV genotypes/subgenotypes for nearly a 16-year period among blood donors confirmed positive for HCV RNA but antibody negative (defined as NAT yield). METHODS A retrospective assessment of demographic characteristics and testing data was used to determine temporal trends and geographical distribution of HCV genotypes/subgenotypes among American Red Cross blood donors confirmed positive as HCV-NAT yield. RESULTS From 2003-2018, 343 donors (0.38 per 100,000 donations; 95% CI, 0.35-0.43) confirmed positive as HCV-NAT-yield cases. Temporal analysis revealed a significant increase in HCV-NAT-yield cases of 54.1% between 2009-2014 (p=0.014), followed by a significant decline of 31.4% between 2015-2018 (p=0.002). Significantly more HCV-NAT-yield cases were detected among first-time donors, non-Hispanic Whites, donors aged 20-29 years, equally likely to be males as females, with the highest frequency in the South (0.52/100,000 donations). Subgenotype 1a (49.6%) was most frequent, followed by 3a (18.7%), 2b (12.5%), 1b (8.5%) and 2a (1.7%). CONCLUSION Voluntary non-remunerated blood donors are at low risk for HCV infection. Since 2015, the frequency of HCV-NAT-yield cases decreased despite an increase of acute HCV infection in the general population. HCV subgenotypes 1a and 3a continue to remain predominant among U.S. blood donors with recent HCV infection.

Abstract
Lipid accumulation and inflammation act together to induce, sustain, and further development of chronic liver disease. Hepatitis C virus (HCV) infection induces metabolic and immune changes in liver macrophages, promoting lipid accumulation and inflammation that synergize and culminate in the development of steatohepatitis and fibrogenesis. Chronic HCV patients have increased liver macrophages with disruptions in cholesterol metabolism and alterations in inflammatory mediators. While HCV-induced changes in inflammatory mediators are well documented, how HCV triggers metabolic change in macrophages is unknown. In this report, we examined the mechanism of macrophage sensing of HCV to cause metabolic impairment and subsequent immune dysfunction. We demonstrate that HCV protein and RNA kinetics in macrophages are distinct from hepatocytes. In macrophages, HCV RNAs and protein accumulate rapidly after exposure but internalized RNAs quickly decline to a low-level set point. Notably, exposure of macrophages to HCV resulted in increased lipids and cholesterol and activation of cholesterol-sensing, immunomodulatory liver X receptors (LXRs). Furthermore, we provide evidence that HCV RNA accumulation in macrophages occurs through scavenging receptors. These results suggest that HCV released from infected hepatocytes stimulates accumulation of lipids and activation of LXR in macrophages contributing to metabolic changes involved in HCV-induced chronic liver disease. Our results provide novel insight into mechanisms through which impaired lipid metabolism in macrophages associated with HCV infection promotes development of liver steatohepatitis and fibrosis.

Abstract
This retrospective cohort study was conducted to determine the prevalence of HCV infections among individuals incarcerated in a state prison system and identify potential contributing factors to HCV infection. North Dakota Department of Corrections and Rehabilitation (NDDOCR) data from 2009 to 2018 was used and period prevalence was calculated for this 10-year time period. The period prevalence of HCV infection was (15.13% (95% CI 14.39–15.90) with a marginally significant (p-value: 0.0542) increasing linear trend in annual prevalence over this period. Multivariate logistic regression analysis was used to identify risk factors associated with HCV infection. The main significant independent risk factors for HCV infection in this incarcerated population were age >40 years [OR: 1.78 (1.37–2.32)]; sex [OR: 1.21 (1.03–1.43)]; race/ethnicity [OR: 1.97 (1.69–2.29)]; history of intravenous drug use (IVDU) [OR: 7.36 (6.41–8.44)]; history of needle or syringe sharing [OR: 7.57 (6.62–8.67)]; and alcohol use [OR: 0.87 (0.77–0.99)]. Study limitations include uncollected information on sexual history, frequency or duration of injection drug use and blood transfusion history of the incarcerated population. Considering the high prevalence of HCV infection and its associated risk factors, it is important to implement prevention programs such as syringe/needle exchanges and counsel with imprisoned IVD users.

Emergency department versus community screening on hepatitis C follow-up care. Am J Emerg Med 2022; 56:151-157. [PMID: 35397356 DOI: 10.1016/j.ajem.2022.03.041] [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: 12/13/2021] [Revised: 03/17/2022] [Accepted: 03/20/2022] [Indexed: 12/09/2022] Open
Abstract
OBJECTIVES Emergency department (ED) hepatitis C virus (HCV) screening programs are proliferating, and it is unknown whether EDs are more effective than traditional community screening at promoting HCV follow-up care. The objective of this study was to investigate whether patients screened HCV seropositive (HCV+) in the ED are linked to care and retained in treatment more successfully than patients screened HCV+ in the community. METHODS A retrospective cohort study was performed including patients screened HCV+ at twelve screening facilities in New Orleans, LA from March 1, 2015 to July 31, 2017. Treatment outcomes, including retention and time to follow-up care, were assessed using the HCV continuum of care model. RESULTS ED patients (n = 3008) were significantly more likely to achieve RNA confirmation (aRR = 1.91, 95% CI = 1.54-2.37), initiate HCV therapy (aRR = 2.23 [1.76-2.83]), complete HCV therapy (aRR = 1.77 [1.40-2.24]), and achieve HCV functional cure (aRR = 2.80 [1.09-7.23]) compared to community-screened patients (n = 322). ED screening was associated with decreased likelihood of fibrosis staging (aRR = 0.65 [0.51-0.82]) and no difference in linkage to specialty care (aRR = 1.03 [0.69-1.53]). In time to follow up, RNA confirmation occurred at faster rates in the ED (aHR = 2.26 [1.86-2.72]), although these patients completed fibrosis staging at slower rates (aHR = 0.49 [0.38-0.63]) than community patients. CONCLUSIONS Compared to community screening, HCV screening in the ED was associated with higher rates of disease confirmation, treatment initiation/completion, and cure. Our findings provide new evidence that EDs may be the most effective setting to screen patients for HCV to promote follow-up care.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection incidence rates in the United States have increased since 2010 as a byproduct of the opioid crisis despite the introduction of direct-acting antiviral agents in 2013. HCV infection is associated with higher rates of liver-related and nonhepatic causes of death. METHODS This study compared demographic characteristics and age-adjusted death rates from 1995 to 2016 among Alaska Native (AN) adults infected with HCV (AK-HepC) to rates among the AN and non-AN adult populations living in Alaska. Liver-related disease (LRD) and other disease-specific age-adjusted death rates were compared between the populations. RESULTS The all-cause death rate among the AK-HepC cohort was 2.2- and 3.4-fold higher than AN and non-AN adults, respectively, and remained stable over time in all populations. The LRD death rate among the AK-HepC cohort was 18- and 11-fold higher than the non-AN and AN, respectively. The liver cancer rate among the AK-HepC cohort was 26-fold higher compared to the Alaska statewide population. The AK-HepC cohort had elevated rates of death associated with nonhepatic diseases with circulatory disease having the highest rate in all populations. Among liver cancer deaths in the AK-HepC cohort, 32% had HCV listed as a contributing cause of death on the death certificate. CONCLUSIONS Death rates in the AK-HepC cohort remained stable since 1995 and higher compared to the general population. People with HCV infection had an elevated risk for all-cause, liver-related, and nonhepatic causes of death. Hepatitis C infection may be underrepresented as a cause of mortality in the United States.

Abstract
Objective Although people with schizophrenia are disproportionately affected by Hepatitis C virus (HCV) compared to the general population, HCV screening among US Medicaid recipients with schizophrenia has not been characterized. Following 1998 CDC recommendations for screening in high-risk populations, we estimated the proportion of Medicaid recipients with and without schizophrenia screened for HCV across states and over time. Examining patterns of screening will inform the current public health imperative to test all adults for HCV now that safer and more effective treatments are available. Methods Data are drawn from 1 353 424 Medicaid recipients aged 15–64 years with schizophrenia and frequency-matched controls from 2002 to 2012. Participants with known HCV infection one year prior and those dual-eligible for Medicare were excluded. Multivariable logistic regression estimated associations between predictor variables and HCV screening. Results HCV screening was low (<4%) but increased over time. Individuals with schizophrenia consistently showed higher screening compared to controls across years and states. Several demographic and clinical characteristics predicted higher screening, especially comorbid HIV (OR = 6.5; 95% CI = 6.0–7.0). Outpatient medical care utilization increased screening by nearly double in 2002 (OR = 1.8; CI = 1.7–1.9) and almost triple in 2012 (OR = 2.7; CI = 2.6–2.9). Conclusions Low screening was a missed opportunity to improve HCV prevention efforts and reduce liver-related mortality among people with schizophrenia. Greater COVID-19 disease severity in HCV patients and the availability of effective HCV treatments increase the urgency to improve HCV screening. Eliminating Medicaid restrictions and expanding statewide HIV policies to include HCV would have multiple public health benefits, particularly for people with schizophrenia.

Abstract
ABSTRACT Hepatitis C virus (HCV) infection is a leading risk factor for hepatocellular carcinoma.We employed a retrospective cohort study design and analyzed 2012-2018 Medicaid claims linked with electronic health records data from the OneFlorida Data Trust, a statewide data repository containing electronic health records data for 15.07 million Floridians from 11 health care systems. Only adult patients at high-risk for HCV (n = 30,113), defined by diagnosis of: HIV/AIDS (20%), substance use disorder (64%), or sexually transmitted infections (22%) were included. Logistic regression examined factors associated with meeting the recommended sequence of HCV testing.Overall, 44.1% received an HCV test. The odds of receiving an initial test were significantly higher for pregnant females (odds ratio [OR]1.99; 95% confidence interval [CI] 1.86-2.12; P < .001) and increased with age (OR 1.01; 95% CI 1.00-1.01; P < .001).Among patients with low Charlson comorbidity index (CCI = 1), non-Hispanic (NH) black patients (OR 0.86; 95% CI 0.81-0.9; P < .001) had lower odds of getting an HCV test; however, NH black patients with CCI = 10 had higher odds (OR 1.41; 95% CI 1.21-1.66; P < .001) of receiving a test. Of those who tested negative during initial testing, 17% received a second recommended test after 6 to 24 months. Medicaid-Medicare dual eligible patients, those with high CCI (OR 1.14; 95% CI 1.11-1.17; P < .001), NH blacks (OR 1.93; 95% CI 1.61-2.32; P < .001), and Hispanics (OR 1.49; 95% CI 1.08-2.06; P = .02) were significantly more likely to have received a second HCV test, while pregnant females (OR 0.71; 95% CI 0.57-0.89; P = .003), had lower odds of receiving it. The majority of patients who tested positive during the initial test (97%) received subsequent testing.We observed suboptimal adherence to the recommended HCV testing among high-risk patients underscoring the need for tailored interventions aimed at successfully navigating high-risk individuals through the HCV screening process. Future interventional studies targeting multilevel factors, including patients, clinicians and health systems are needed to increase HCV screening rates for high-risk populations.

Abstract
Background Despite constituting the largest segment of the correctional population, individuals on probation remain largely unstudied with respect to hepatitis C virus (HCV) testing and linkage to care. We implemented an HCV testing and patient navigation program at an adult probation department. Methods Adults were tested at a local probation department with a rapid point-of-care HCV antibody (Ab) assay followed by a laboratory-based HCV ribonucleic acid (RNA) assay if anti-HCV positive. All individuals received counseling rooted in harm reduction principles. Individuals testing positive for HCV Ab were immediately linked to a patient navigator in person or via telephone. The patient navigator assisted patients through cure unless the patient was lost to follow-up. Study participation involved an optional survey and optional point-of-care human immunodeficiency virus test. Results Of 417 individuals tested, 13% were HCV Ab positive and 65% of those tested for HCV RNA (34 of 52) had detectable HCV RNA. Of the 14 individuals who linked to an HCV treatment provider, 4 completed treatment, as measured by pharmacy fill documentation in the electronic medical record, and 1 obtained sustained virologic response. One hundred ninety-three individuals tested for HIV; none tested positive. Conclusions The study cohort had a higher HCV seroprevalence than the general population (13% vs 2%), but linkage to care, completion of HCV treatment, and successful test-of-cure rates were all low. This study indicates that HCV disproportionately impacts adults on probation and prioritizing support for testing and linkage to care could improve health in this population. Colocalization of HCV treatment within probation programs would reduce the barrier of attending a new institution and could be highly impactful.

Plasma virome and the risk of blood-borne infection in persons with substance use disorder. Nat Commun 2021; 12:6909.

Abstract
There is an urgent need for innovative methods to reduce transmission of bloodborne pathogens like HIV and HCV among people who inject drugs (PWID). We investigate if PWID who acquire non-pathogenic bloodborne viruses like anelloviruses and pegiviruses might be at greater risk of acquiring a bloodborne pathogen. PWID who later acquire HCV accumulate more non-pathogenic viruses in plasma than matched controls who do not acquire HCV infection. Additionally, phylogenetic analysis of those non-pathogenic virus sequences reveals drug use networks. Here we find first in Baltimore and confirm in San Francisco that the accumulation of non-pathogenic viruses in PWID is a harbinger for subsequent acquisition of pathogenic viruses, knowledge that may guide the prioritization of the public health resources to combat HIV and HCV. Spread of bloodborne infections, such as HCV and HIV, is a problem, particularly amongst people who inject drugs (PWID). Here, the authors describe and then confirm in observational PWID cohorts that those with more non-pathogenic viruses in plasma were more likely later to acquire HCV than PWID who had fewer of these non-pathogenic viruses.

Hepatitis C virus care cascade in persons experiencing homelessness in the United States in the era of direct-acting antiviral agents: A scoping review. J Viral Hepat 2021; 28:1506-1514. [PMID: 34314081 PMCID: PMC9829430 DOI: 10.1111/jvh.13583] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 05/26/2021] [Accepted: 07/12/2021] [Indexed: 01/12/2023]
Abstract
The hepatitis C virus (HCV) care cascade has been well characterized in the general United States population and other subpopulations since curative medications have been available. However, information is limited on care cascade outcomes in persons experiencing homelessness. The main objective of this study was to map the available evidence on HCV care cascade outcomes in people experiencing homelessness in the U.S. in the era of direct-acting antiviral agents (DAAs). Primary and secondary outcomes included linkage to care (evaluation by a provider that can treat HCV) and sustained virologic response (SVR) or cure. Exploratory outcomes included other cascade data, like treatment initiation, which precedes SVR. PubMed was the primary database accessed for this scoping review. We characterized the HCV care cascade in people experiencing homelessness using sources of evidence published in 2014 onwards that reported the proportions of persons who were linked to care, achieved SVR, and completed other cascade steps. We synthesized our results into a scoping review. The proportion of persons linked to care among chronically infected cohorts with unstable housing ranged from 29.3% to 88.7%. Among those chronically infected, 5%-58.8% were started on DAAs and 5%-50% achieved SVR. In conclusion, these results show that persons experiencing homelessness achieve high rates of linkage to care in non-specialist community-based settings compared to the general U.S. population pre-DAAs. However, DAA initiation was found to be a rate-limiting step along the care cascade, resulting in commensurate low rates of cure.

Hepatitis C Treatment Among Commercially or Medicaid-Insured Individuals, 2014-2018. Am J Prev Med 2021; 61:716-723. [PMID: 34362617 DOI: 10.1016/j.amepre.2021.05.017] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2021] [Revised: 04/29/2021] [Accepted: 05/05/2021] [Indexed: 12/16/2022]
Abstract
INTRODUCTION The proportion of individuals infected with hepatitis C virus that receive direct-acting antiviral treatment is unclear. METHODS The proportion of commercially or Medicaid-insured patients receiving hepatitis C virus treatment was estimated using administrative claims data obtained from MarketScan and Multi-State Medicaid obtained on January 6, 2020. Validated algorithms derived from standardized procedures and International Classification of Diseases diagnosis codes were used to identify enrollees with chronic hepatitis C; analysis (performed November 30, 2020) was restricted to adults continuously enrolled with prescription drug coverage for >6 months before and after their index hepatitis C viral load test claim date from January 2014 through December 2018. Prescription drug claims using National Drug Codes were used for hepatitis C virus drugs. The proportion of treated patients by demographic and clinical characteristics was described, and associations with treatment were modeled using multivariable-adjusted hazard ratios and 95% CIs by insurance status. RESULTS Of patients with chronic hepatitis C, 12,090 of 17,562 (69%) with commercial insurance and 8,112 of 27,328 (30%) with Medicaid were treated. Commercially insured patients with opioid use disorder (hazard ratio=0.78, 95% CI=0.72, 0.85), alcohol use disorder (hazard ratio=0.85, 95% CI=0.79, 0.91), severe mental illness (hazard ratio=0.92, 95% CI=0.87, 0.98), chronic kidney disease (hazard ratio=0.75, 95% CI=0.69, 0.82), or HIV infection (hazard ratio=0.74, 95% CI=0.66, 0.82) were less likely to be treated. Medicaid patients with opioid (hazard ratio=0.64, 95% CI=0.61, 0.68) or alcohol use disorders (hazard ratio=0.83, 95% CI=0.79, 0.88) were less likely to be treated. CONCLUSIONS Hepatitis C virus treatment gaps were identified using administrative claims data among patients with commercial and Medicaid insurance.

HIV Prevention Trials Network 078: High Prevalence of Hepatitis C Virus Antibodies Among Urban US Men Who Have Sex With Men, Independent of Human Immunodeficiency Virus Status. Clin Infect Dis 2021; 73:e2205-e2210. [PMID: 33346798 PMCID: PMC8492204 DOI: 10.1093/cid/ciaa1869] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Sexual transmission of hepatitis C virus (HCV) is uncommon, yet documented among men who have sex with men (MSM), primarily among those with human immunodeficiency virus (HIV). METHODS In the HIV Prevention Trials Network 078 study (HPTN 078), which assessed an integrated strategy to achieve HIV viral suppression, 1305 MSM were screened across 4 geographically diverse US cities. At screening, demographic/behavioral/psychosocial questionnaires were completed, along with HIV and HCV testing. Multivariable logistic regression was used to evaluate associations with HCV antibody positivity. RESULTS Among the 1287 (99%) of the MSM with HCV antibody results, the median age was 41, 69% were black, 85% had a high school education or more, 35% were employed, 70% had HIV, and 21% had undergone substance use counseling. The median lifetime number of male sexual partners was 17 (interquartile range, 6-50), and 246 (19%) were HCV antibody positive. HCV antibody positivity was high in MSM with HIV (20%) and MSM without HIV (17%) (P = .12) and was higher in those receiving substance use counseling (36%) than in those who had not (15%) (P ≤ .01). Substance use counseling (odds ratio, 2.51; 95% confidence interval, 1.80-3.51) and unstable housing (2.16; 1.40-3.33) were associated with HCV antibody positivity. CONCLUSIONS Nearly 1 in 5 MSM screened for HPTN 078 have been infected with HCV. The prevalence is high regardless of HIV status and is high even in those who did not undergo substance use counseling. In HIV burden networks, high HCV infection prevalence may occur in MSM without HIV. As implementation of preexposure prophylaxis expands and condom use declines, routine HCV counseling and screening among MSM are important.
