Abstract
Viral hepatitis represents a major danger to public health, and is a globally leading cause of death. The five liver-specific viruses: Hepatitis A virus, hepatitis B virus, hepatitis C virus, hepatitis D virus, and hepatitis E virus, each have their own unique epidemiology, structural biology, transmission, endemic patterns, risk of liver complications, and response to antiviral therapies. There remain few options for treatment, in spite of the increasing prevalence of viral-hepatitis-caused liver disease. Furthermore, chronic viral hepatitis is a leading worldwide cause of both liver-related morbidity and mortality, even though effective treatments are available that could reduce or prevent most patients' complications. In 2016, the World Health Organization released its plan to eliminate viral hepatitis as a public health threat by the year 2030, along with a discussion of current gaps and prospects for both regional and global eradication of viral hepatitis. Today, treatment is sufficiently able to prevent the disease from reaching advanced phases. However, future therapies must be extremely safe, and should ideally limit the period of treatment necessary. A better understanding of pathogenesis will prove beneficial in the development of potential treatment strategies targeting infections by viral hepatitis. This review aims to summarize the current state of knowledge on each type of viral hepatitis, together with major innovations.

Using the Diabetes Care System for a County-Wide Hepatitis C Elimination: An Integrated Community-Based Shared Care Model in Taiwan. Am J Gastroenterol 2024; 119:883-892. [PMID: 38084857 PMCID: PMC11062613 DOI: 10.14309/ajg.0000000000002624] [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: 06/21/2023] [Accepted: 10/16/2023] [Indexed: 01/30/2024]
Abstract
INTRODUCTION Despite the serious risks of diabetes with hepatitis C virus (HCV) infection, this preventable comorbidity is rarely a priority for HCV elimination. We aim to examine how a shared care model could eliminate HCV in patients with diabetes (PwD) in primary care. METHODS There were 27 community-based Diabetes Health Promotion Institutes in each township/city of Changhua, Taiwan. PwD from these institutes from January 2018 to December 2020 were enrolled. HCV screening and treatment were integrated into diabetes structured care through collaboration between diabetes care and HCV care teams. Outcome measures included HCV care continuum indicators. Township/city variation in HCV infection prevalence and care cascades were also examined. RESULTS Of the 10,684 eligible PwD, 9,984 (93.4%) underwent HCV screening, revealing a 6.18% (n = 617) anti-HCV seroprevalence. Among the 597 eligible seropositive individuals, 507 (84.9%) completed the RNA test, obtaining 71.8% positives. Treatment was initiated by 327 (89.8%) of 364 viremic patients, and 315 (86.5%) completed it, resulting in a final cure rate of 79.4% (n = 289). Overall, with the introduction of antivirals in this cohort, the prevalence of viremic HCV infection dropped from 4.44% to 1.34%, yielding a 69.70% (95% credible interval 63.64%-77.03%) absolute reduction. DISCUSSION Although HCV prevalence varied, the care cascades achieved consistent results across townships/cities. We have further successfully implemented the model in county-wide hospital-based diabetes clinics, eventually treating 89.6% of the total PwD. A collaborative effort between diabetes care and HCV elimination enhanced the testing and treatment in PwD through an innovative shared care model.

Abstract
BACKGROUND & AIMS Texas has the highest age-adjusted incidence rate of hepatocellular carcinoma (HCC) in the United States. The Cancer Prevention and Research Institute of Texas has funded the Texas Collaborative Center for Hepatocellular Cancer (TeCH) to facilitate HCC research, education, and advocacy activities with the overall goal of reducing HCC mortality in Texas through coordination, collaboration, and advocacy. METHODS On September 17, 2022, TeCH co-sponsored a multi-stakeholder conference on HCC with the Baker Institute Center for Health and Biosciences. This conference was attended by HCC researchers, policy makers, payers, members from pharmaceutical industry and patient advocacy groups in and outside of Texas. This report summarizes the results of the conference. RESULTS The goal of this meeting was to identify different strategies for preventing HCC and evaluate their readiness for implementation. CONCLUSIONS We call for a statewide (1) viral hepatitis elimination program; (2) program to increase nonalcoholic steatohepatitis and obesity awareness; (3) research program to develop health care models that integrate alcohol associated liver disease treatment and treatment for alcohol use disorder; and (4) demonstration projects to evaluate the effectiveness of identifying and linking patient with advanced fibrosis and cirrhosis to clinical care.

Clinician barriers, perceptions, and practices in treating patients with hepatitis C virus and substance use disorder in the United States. Prev Med Rep 2023; 32:102138. [PMID: 36865395 PMCID: PMC9971512 DOI: 10.1016/j.pmedr.2023.102138] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 12/19/2022] [Accepted: 02/10/2023] [Indexed: 02/16/2023] Open
Abstract
The likelihood of clinicians prescribing direct-acting antiviral (DAA) therapy for patients with chronic hepatitis C virus (HCV) and substance use disorder (SUD) was assessed via a survey emailed throughout the United States to clinicians (physicians and advanced practice providers) in gastroenterology, hepatology, and infectious disease specialties. Clinicians' perceived barriers and preparedness and actions associated with current and future DAA prescribing practices of HCV-infected patients with SUD were assessed. Of 846 clinicians presumably receiving the survey, 96 completed and returned it. Exploratory factor analyses of perceived barriers indicated a highly reliable (Cronbach alpha = 0.89) model with five factors: HCV stigma and knowledge, prior authorization requirements, and patient- clinician-, and system-related barriers. In multivariable analyses, after controlling for covariates, patient-related barriers (P < 0.01) and prior authorization requirements (P < 0.01) were negatively associated with the likelihood of prescribing DAAs. Exploratory factor analyses of clinician preparedness and actions indicated a highly reliable (Cronbach alpha = 0.75) model with three factors: beliefs and comfort level; action; and perceived limitations. Clinician beliefs and comfort levels were negatively associated with the likelihood of prescribing DAAs (P = 0.01). Composite scores of barriers (P < 0.01) and clinician preparedness and actions (P < 0.05) were also negatively associated with the intent to prescribe DAAs. Conclusion These findings underscore the importance of addressing patient-related barriers and prior authorization requirements-significant problematic barriers-and improving clinicians' beliefs (e.g., medication-assisted therapy should be prescribed before DAAs) and comfort levels for treating patients with HCV and SUD to enhance treatment access for patients with both HCV and SUD.

JOURNAL OF MEDICAL EDUCATION AND CURRICULAR DEVELOPMENT 2023; 10:23821205231184362. [PMID: 37378042 PMCID: PMC10291854 DOI: 10.1177/23821205231184362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 06/02/2023] [Indexed: 06/29/2023]
Abstract
OBJECTIVES Improved knowledge of hepatitis C virus (HCV) screening, linkage to care, and treatment is needed among nonspecialist medical professionals to combat the HCV epidemic. The authors sought to implement and analyze the impact of an HCV curriculum for primary care professionals (PCPs) across the state of Vermont, USA. METHODS This investigation was a retrospective analysis of uptake of a Vermont HCV educational curriculum and its impact on HCV direct-acting antiviral (DAA) prescribing rates within the state before and after the study period. The curriculum was delivered online and in-person over 2 years from 2019 to 2020. The primary outcome was health care professional performance on a pre- and post-curriculum short-term knowledge assessment exam. The secondary outcome was assessing the number of unique healthcare professionals within a single payor database prescribing DAA treatment for HCV in Vermont before and after the study intervention, from January 1, 2017 until December 1, 2021. RESULTS There were 31 unique respondents on the pre- and post-intervention examinations, which represented 9% of known participants. Respondents included physicians (n = 15), nurse practitioners (n = 8), and nurses (n = 8). Pre- and post-intervention knowledge scores increased significantly across all provider groups, from 3.2 (SD 0.6) to 4.5 (SD 0.4) 1 to 5 scale (P = .01). The total number of unique HCV DAA therapy prescribers decreased over the study period, from 17 in 2017 to 9 in 2021. CONCLUSIONS A Vermont statewide HCV curriculum for PCPs was successful at increasing short-term HCV-related knowledge. However, this did not obviously translate to an increase in new professionals treating HCV.
