Abstract
Introduction: With availability of direct-acting antivirals (DAA), most persons with inherited bleeding disorders are currently cured of hepatitis C virus (HCV) infection. The risk of liver-related complications following HCV cure has not been reported for this population. Aim: Reporting liver-related complications during long-term chronic HCV infection and following sustained virological

response (SVR) in this population. Methods: Retrospective follow-up of a prospective single-centre cohort of HCV antibody-positive persons with inherited bleeding disorders. Primary endpoint was liver-related complications [hepatocellular carcinoma (HCC), decompensated cirrhosis, bleeding gastroesophageal varices]. Liver-related complications were reported separately during chronic HCV and following SVR, stratified for interferon-based and DAA-based SVR. Results: In total 309/381 (81%) HCV antibody-positive individuals developed chronic HCV infection. Median follow-up was 44 years [interquartile range (IQR): 34–50]. Liver-related complications occurred in 36/309 (12%) of individuals with chronic HCV infection after median 31 years of chronic infection. Of 199 individuals with SVR, 97 were cured with interferon-based regimens and 102 with DAA after median infection durations of 29 and 45 years, respectively. At end of follow-up, respectively, 21% and 42% had advanced fibrosis or cirrhosis. Post-SVR, seven (4%) individuals had a liver-related complication, mainly HCC (n = 4). Incidence of liver-related complications per 100 patient-years post-SVR follow-up was.2 for interferon-cured and 1.0 for DAA-cured individuals (p =.01). Conclusion: Successful HCV treatment does not eliminate the risk of liver-related complications in persons with inherited bleeding disorders. Due to higher baseline risk, incidence was higher after DAA than interferon-based SVR. We advise continuing HCC surveillance post-SVR in all with advanced fibrosis or cirrhosis.
