| Abstract: |
Background: The histological improvement in liver fibrosis in patients with hepatitis C who achieved a sustained virological response (SVR) to direct-acting antiviral (DAA) treatment has not been comprehensively investigated. Therefore, we assessed the histological changes in liver fibrosis among patients with hepatitis C who underwent long-term follow-up after achieving SVR to treatment with DAA. Methods: This retrospective study enrolled 71 patients with hepatitis C who achieved SVR to treatment with DAA. Changes in histological liver fibrosis and fibrosis biomarkers (hyaluronic acid, type 4 collagen 7S, Mac-2 binding protein glycosylation isomer, autotaxin, and Fibrosis-4 index) were assessed before and 5 years after treatment. Transient elastography using the FibroScan® device was performed 5 years after treatment. Advanced fibrosis and cirrhosis were defined as Ishak fibrosis scores of ≥ 4 and ≥ 5, respectively. Results: Histological liver fibrosis significantly regressed after SVR. Fibrosis biomarkers were significantly reduced after SVR. Transient elastography was the most helpful after evaluating the predictive performance of advanced fibrosis and cirrhosis after SVR, with an area under the receiver operating characteristic curve of 0.965 and a cut-off value of 6.75 kPa. The cut-off values of serum fibrosis biomarkers for identifying advanced fibrosis and cirrhosis after SVR were lower than those before treatment. Conclusions: Long-term SVR to treatment with DAA ameliorated histological liver fibrosis. Noninvasive tests helped predict the degree of liver fibrosis after SVR, but their cut-off values should be redefined to avoid underestimation of liver fibrosis. [ABSTRACT FROM AUTHOR] |
