Hepatitis C epidemiology and treatment outcomes in Italy: Impact of the DAA era and the COVID‐19 pandemic

Abstract

AbstractHCV infection poses a global health threat, with significant morbidity and mortality. This study examines HCV trends in a large Italian region from 2015 to 2022, considering demographic changes, evolving clinical profiles, treatment regimens and outcomes, including the impact of the COVID‐19 pandemic. This multicentre retrospective study analysed demographics, clinical histories and risk factors in 6882 HCV patients. The study spanned before and after the direct‐acting antiviral (DAA) era, and the COVID‐19 period, focusing on treatment outcomes (SVR12, non‐SVR12 and patients lost to follow‐up). Statistical methods included ANOVA, multinomial logistic regression, Kruskal–Wallis test and chi‐square analysis, and were conducted adhering to the intention‐to‐treat (ITT) principle. The cohort, mainly Italian males (average age 58.88), showed Genotype 1 dominance (56.6%) and a high SVR12 rate (97.5%). The pandemic increased follow‐up losses, yet SVR12 rates remained stable, influenced by factors like age, gender, cirrhosis and comorbidities. Despite COVID‐19 challenges, the region sustained high SVR12 rates in HCV care, emphasising the importance of sustained efforts in HCV care. Continuous screening and targeted interventions in high‐risk populations are crucial for achieving WHO elimination targets. The study highlights the resilience of HCV care during the pandemic and provides insights for future public health strategies.
