Hepatitis C Virus Clearance by Direct-acting Antiviral Results in Rapid Resolution of Hepatocytic Injury as Indicated by Both Alanine Aminotransferase and Aspartate Aminotransferase Normalization

Background and Aims: Hepatitis C virus (HCV) infection results in hepatocytic injury with elevation of both alanine aminotransferase (ALT) and aspartate aminotransferase (AST). It remains to be determined if direct-acting antiviral treatment can terminate hepatocytic injury following virologic response. To this end, we evaluated the pattern and predicting factors of ALT and AST normalization during and after direct-acting antiviral treatment with sustained virologic response at 12 weeks (SVR12). Methods: Single-center retrospective study on 115 HCV-infected patients who achieved SVR12 was performed. Results: At treatment week 2, 100% and 45.9% showed decline in HCV RNA to
