Effect of disease stage and treatment outcomes on the dynamics of liver functions during and after treatment of hepatitis C with directly acting antivirals

Abstract

Background: Virus C infection is recently treated successfully with plenty of direct antiviral agents (DAAs). We aimed to evaluate the effect of disease stage and treatment outcome on the dynamics of liver functions during treatment of hepatitis C with DAAs.

Methods: We reported the liver function in 2354 subjects diagnosed as chronic hepatitis C before, during and after treatment with different DAAs regimens. Patients were classified into two groups according to treatment response with further subclassification according to the presence or absence of cirrhosis, and changes in liver functions were compared in each group and subgroup.

Results: Totally 2213 (94%) achieved sustained virological response (SVR) to DAAs therapy with significant improvement in all liver biochemistry. Also, there was an improvement in the non-SVR group's liver enzymes in relapsers during and after treatment; however, there was no improvement in serum albumin. We noticed a slight increase in serum bilirubin at weeks 4 and 8 for both groups.

Conclusion: DAAs therapy is associated with improvement of the liver biochemical profile and improved outcome in the majority of chronic hepatitis C virus patients due to suppression of viral replication. However, the long-term impact of DAAs therapy needs to be further evaluated.
