Time‐dependent improvement of liver inflammation, fibrosis and metabolic liver function after successful direct‐acting antiviral therapy of chronic hepatitis C

Sofosbuvir‐based direct‐acting antiviral (DAA) therapy generally cures chronic hepatitis C (CHC) infections, however, the effects on the underlying liver disease and the potential rate of recovery are unclear. We aimed to investigate the effects of DAA therapy on liver inflammation, fibrosis, metabolic function and cognitive function and the time course in CHC patients with advanced liver disease. Seventy‐one CHC patients with advanced liver disease were studied before, during and one year after successful sofosbuvir‐based DAA therapy. Liver inflammation was assessed by plasma sCD163 and sMR levels (ELISA), fibrosis by liver stiffness (transient elastography), function by galactose elimination capacity (GEC) and cognitive performance by continuous reaction time (CRT). During DAA therapy, we observed a rapid sCD163 decline from baseline to end of treatment (6.9 vs 3.8 mg/L, P
