Research advances in predictors of treatment responses to pegylated interferon alpha in patients with chronic hepatitis B / 临床肝胆病杂志

ABSTRACT

The treatment responses to pegylated interferon alpha (PEG-IFNα)in patients with chronic hepatitis B (CHB)are associated with the genetic polymorphisms,immune status,hepatitis B virus genotype,and viral load of the host.This article reviews the recent studies on influential factors for the responses to PEG-IFNαin CHB patients.The important predictors of the clearance and seroconversion of HB-sAg and HBeAg and sustained virological response include interleukin-28B (IL-28B)gene polymorphism,baseline level of interferon-inducible protein-10,IL-17A,IL-10,tumor necrosis factor-α,viral load and genotype,and changes in serum HBsAg and HBeAg levels at weeks 12 and 24 of treatment.
