Abstract

Aim:

Although interferon (IFN)-free antiviral therapy is expected to improve the treatment response for chronic hepatitis C, the effect on liver function and liver fibrosis is unknown. In this study, we analyzed the long-term follow up of liver function parameters and liver fibrosis markers in genotype 1b hepatitis C virus (HCV)-infected patients treated with daclatasvir and asunaprevir.

Methods:

Thirty patients were treated with daclatasvir and asunaprevir for 24 weeks, and 26 patients achieved sustained virological response (SVR). We measured liver function parameters, serum alanine aminotransferase (ALT) and albumin levels and liver fibrosis markers, hyaluronic acid, type IV collagen and Mac-2-binding protein (M2BPGi) before and after (median, 27 months; range, 17–47) completion of the treatment in SVR and non-SVR patients. We also measured serum α-fetoprotein (AFP) levels during the therapy and follow-up period.

Results:

Pretreatment serum ALT and albumin levels and liver fibrosis markers were similar between SVR and non-SVR patients. Twenty-seven months after treatment, serum ALT and albumin levels significantly improved only in SVR patients. Although there was no change in non-SVR patients, platelet count and serum liver fibrosis markers significantly improved in SVR patients. Serum AFP levels rapidly decreased during the treatment in both SVR and non-SVR patients, but the change was significant only in SVR patients.

Conclusion:

Successful viral eradication by IFN-free daclatasvir and asunaprevir therapy could lead to improved liver function parameters and reduced liver fibrosis markers and AFP levels. This treatment has the potential to improve liver fibrosis and decrease the incidence of hepatocarcinogenesis.
