The aims of this prospective study were as follows: (1) to describe the natural history of chronic hepatitis B virus (HBV) infection in a large cohort of untreated children followed at a single centre and (2) to evaluate whether or not the new European Association for the Study of Liver (EASL) classification for the phases of HBV infection in adults can be used for children. All children who presented at the Liver Unit of our hospital from 1 January 1987 to 31 December 2019 and were diagnosed with chronic HBV infection were enrolled. The final sample consisted of 152 children. The median duration of the follow-up was 83 months (range 7-232). At baseline, 125 patients (82.2%) were HBeAg positive (85.3% abnormal alanine aminotransferase (ALT) levels), and 24 (15.8%) were HBeAg-negative (93.3% abnormal ALT). At the end of the observation period, 62 of the HBeAg-positive patients (40.7%) achieved HBeAg seroconversion (median age 9.45 years, range 0.8-19) and 2 (1.4%) achieved HBsAg seroconversion. Elevated ALT serum levels at baseline (P =.011), lower baseline HBV DNA levels (P <.001) and Asian ethnicity (P =.0001) were identified as predisposing factors towards HBeAg seroconversion. EASL criteria could not be applied to 43.3% and 43.5% of the children at baseline and at end of observation, respectively, that were grouped into an undetermined phenotype category. According to the results of the present study, the new EASL guidelines for adults with HBV infection cannot be applied in a satisfactory manner in children.

Abstract

The aims of this prospective study were as follows: (1) to describe the natural history of chronic hepatitis B virus (HBV) infection in a large cohort of untreated children followed at a single centre and (2) to evaluate whether or not the new European Association for the Study of Liver (EASL) classification for the phases of HBV infection in adults can be used for children. All children who presented at the Liver Unit of our hospital from 1 January 1987 to 31 December 2019 and were diagnosed with chronic HBV infection were enrolled. The final sample consisted of 152 children. The median duration of the follow-up was 83 months (range 7-232). At baseline, 125 patients (82.2%) were HBeAg positive (85.3% abnormal alanine aminotransferase (ALT) levels), and 24 (15.8%) were HBeAg-negative (93.3% abnormal ALT). At the end of the observation period, 62 of the HBeAg-positive patients (40.7%) achieved HBeAg seroconversion (median age 9.45 years, range 0.8-19) and 2 (1.4%) achieved HBsAg seroconversion. Elevated ALT serum levels at baseline (P =.011), lower baseline HBV DNA levels (P <.001) and Asian ethnicity (P =.0001) were identified as predisposing factors towards HBeAg seroconversion. EASL criteria could not be applied to 43.3% and 43.5% of the children at baseline and at end of observation, respectively, that were grouped into an undetermined phenotype category. According to the results of the present study, the new EASL guidelines for adults with HBV infection cannot be applied in a satisfactory manner in children.
