This long-term prospective cohort study aimed to elucidate the predictors of developing HBeAg-negative hepatitis in chronic HBV-infected subjects followed from childhood to adulthood. We followed 434 HBeAg-positive chronic HBV-infected patients from a median age of 7.22 years (interquartile range 4.31-10.21 years). Spontaneous HBeAg seroconversion occurred in 359 subjects at a median age of 13.93 years (interquartile range 8.76-20.59 years), and 75 subjects developed HBeAg seroconversion after antiviral therapy. These patients were followed for a median of 14.40 years (interquartile range 6.14-22.02 years) after HBeAg seroconversion. Clinical data were analyzed to delineate the predictors of developing HBeAg-negative hepatitis. The HBV basal core promoter and precore/core gene sequences were also evaluated in subjects with and without HBeAg-negative hepatitis. The overall annual incidence of HBeAg-negative hepatitis was 0.37% (95% confidence internal 0.35-0.39) in spontaneous HBeAg seroconverters. The overall annual incidence of HBeAg-negative hepatitis increased to 2.64% in lamivudine-treated subjects but did not increase in those treated with interferon-alpha (0.58%). Male gender (hazard ratio = 3.15), HBV genotype C (hazard ratio = 4.40), HBeAg seroconversion after 18 years of age (hazard ratio = 2.46), and lamivudine therapy prior to HBeAg seroconversion (hazard ratio = 1.42) were predictors of HBeAg-negative hepatitis in HBeAg seroconverters (P < 0.05). HBeAg-negative hepatitis subjects carried more A1762T/G1764A, C2063A, and A2131C HBV gene mutations than those without HBeAg-negative hepatitis. Conclusions: HBeAg seroconversion during childhood predicts a lower risk of HBeAg-negative hepatitis in later life. Interferon-alpha therapy may be an effective antiviral therapy beneficial in chronic HBV-infected children with severe inflammation that facilitates HBeAg seroconversion in earlier life. ? 2016 by the American Association for the Study of Liver Diseases. |
