Core Tip

Core tip: Interferon-α (IFNα) is the first line treatment for chronic hepatitis B virus (HBV) infection (CHB). However, its efficiency differs and biomarkers for predicting responses of IFNα are needed. The current study performed an epidemiologic study to investigate the association between Interferon-induced protein with tetratricopeptide repeats 1 (IFIT1) polymorphisms and clinical responses of IFNα treatment in newly diagnosed chronic HBV infection patients among Chinese population. We identified that IFIT1 polymorphism rs303218 could be a predictor for the end point virological response of IFNα therapy. The finding may provide insight to the potential role of IFIT1 in the individualized treatment of CHB in the future.
