Core Tip

Core tip: Chronic hepatitis D is a difficult to treat infection. Six months post treatment response is seen only in one quarter of the patients treated with pegylated interferon alfa (PEG-IFNα). In an attempt to improve the response of PEG-IFN, we combined entecavir. This is the first study to evaluate the efficacy of PEG-IFN with entecavir compared to PEG-IFN alone for the treatment of hepatitis D infection. Our study showed that the combination treatment did not have any additional benefit in terms of hepatitis D virus RNA suppression and hepatitis B surface antigen reduction as compared to PEG-IFN alone.
