Abstract: 

Background: After treatment cessation, a high prevalence of relapse was reported in chronic hepatitis B (CHB) patients in China, especially in nucleot (s) ide analogues (NUCs) -experienced patients. Re-treatment for these patients remains unsolved.
Objectives: This study aims to evaluate the efficacy of PEGylated interferon in HBeAg positive patients with exposure to antiviral therapy.
Patients and Methods: A total of 55 treatment-experienced, HBeAg positive Chinese patients were enrolled in this study. Of these patients, 33 were NUCs-experienced and 22 were interferon-experienced. PEGylated interferon was administered to 34 patients; and 21 patients were retreated with conventional interferon.
Results: Of the 34 treatment-experienced patients who received PEGylated interferon, 52.9% achieved virologic response, and 41.2% achieved HBeAg loss and seroconversion. Patients who were treated with PEGylated interferon for 48 weeks achieved higher virologic response (80%); HBeAg loss (60%); HBeAg seroconversion (60%); and HBsAg loss (5%) than patients treated for 24 weeks with PEGylated interferon. Their responses were also higher than those who were treated with conventional interferon. HBeAg seroconversion in treatment-experienced patients was independently associated with 48-week PEGylated interferon therapy duration.
Conclusions: PEGylated interferon was effective in treatment-experienced patients with HBeAg positive CHB, and showed higher rates of virological response, HBeAg loss, and seroconversion. The results provide important information regarding the role of retreatment with PEGylated interferon in treatment-experienced HBeAg positive patients.
