Popis: Abstract Background Direct-acting antivirals (DAAs) have revolutionized the therapy of HCV infection with higher sustained virological response (SVR) rates. Fibrosis regression after achieving SVR to DAA remains to be evaluated in chronic hepatitis C patients. One of the main inquiries here is what occurs with liver fibrosis after achieving a SVR, albeit the current DAA was not intended to be antifibrotic. Liver biopsy was replaced by various non-invasive methods, like FIB4 score and fibroscan. The aim of the study was to evaluate the impact of SVR following DAAs on liver fibrosis in chronic HCV patients. Results Five hundred of 1170 F4 treated patients (42.7%) improved and became 190 F3, 90 F2, and 220 F1. Also, 40 of 60 F3 patients improved and became 10 F2 and 30 F1. Also, 350 of 1230 treated patients (28.4%) transited from significant fibrosis (≥F3) to non-significant fibrosis (≤F2). There was a significant improvement of FIB-4 (p
