About

Compared to nucleoside/nucleotide analogues, peginterferon alfa 2a/2b may has more therapeutic efficacy in hepatitis B surface antigen or e antigen seroconversion and anti-tumor occurrence in chronic hepatitis b patients. We design this study to investigate treatment of peginterferon alfa 2a/2b in anti-virus treatment naive patients with HBV related liver fibrosis.

Full description

Compared to nucleoside/nucleotide analogues, peginterferon alfa 2a/2b may has more therapeutic efficacy in hepatitis B surface antigen or e antigen seroconversion and anti-tumor occurrence in chronic hepatitis b patients. But there still lacks of studies on peginterferon alfa 2a or 2b treatment in patients with HBV related liver fibrosis. We design this study to investigate optimized treatment of peginterferon alfa 2a/2b, comparing to nucleoside/nucleotide analogues, in anti-virus treatment naive patients with HBV related liver fibrosis.
