OBJECTIVES: The purpose of this study was to analyze the clinical characteristics of chronic hepatitis B (CHB) cured by antiviral therapy.
METHODS: Forty-two patients with CHB were enrolled. All patients had been treated with peginterferon (Peg-IFN) in combination with nucleoside analogue (NA) therapy for variable amounts of time, and all had been successfully cured of the disease.
RESULTS: The combined treatment time for all participants was 124.7 ± 58.8 weeks, and the average Peg-IFN treatment time was 102.6 ± 56.1 weeks. At 24 weeks, Hepatitis B surface antigen (HBsAg) and Hepatitis B e antigen (HBeAg) had decreased more than 50% from baseline. Multivariate logistic regression analysis of the week 96 HBsAg-clearing group and the non-HBsAg-clearing group showed a statistically significant difference in baseline HBV DNA levels and week 48 HBsAg levels. Those which baseline HBV DNA was < 2.75 log10 IU/mL, and week 48 HBsAg levels were < 0.88 log10 IU/mL were more likely to achieve rapid HBsAg clearance at 96 weeks. This suggests that low levels of baseline HBV DNA and week 48 HBsAg are a predictor of rapid HBsAg clearance at 96 weeks.
CONCLUSIONS: Individualized extension of combination therapy to more than 96 weeks depending on the patient's response and adverse reaction conditions can help achieve a clinical cure. Patients with low baseline HBV DNA and low HBsAg levels at 48 weeks achieve HBsAg clearance more quickly than other populations.
