Abstract

Objective To observe the patterns of viral responses and changes of alanine aminotransferase (ALT) levels in HBeAg-negative patients one year after withdrawal of antiviral drugs.Methods The clinical data on HBeAg negative chronic hepatitis B patients (CHB) who took nucleotide analogues (NAs) and met the inclusion criteria was collected in our hospital. The clinical characteristics at the time of withdrawal of NAs and one year after treatment were analyzed. Results From January 2017 to July 2020, there were 40 CHB patients who met the inclusion criteria, 19 of whom were HBeAg positive and 21 were HBeAg negative. HBeAg-negative patients were more likely to have their HBV DNA rebounded(P=0.031) and ALT elevated(P=0.017) than HBeAg- positive patients after withdrawal of NAs. HBeAg-negative patients with rebounding HBV DNA after withdrawal of NAs had their HBsAg titers gradually decreased in the 1st month, 3rd month, 6th month, and 12th month. There was statistically significant difference compared with the HBV DNA-negative group. The ALT levels of patients with rebounding HBV DNA gradually increased, but hepatitis B reoccurred only in one patient.Conclusions One year after withdrawal of NAs, the rebound rate of HBV DNA is high and the ALT level is elevated in HBeAg negative patients.For patients with rebounding HBV DNA, HBsAg titers are decreased, which might contribute to the clearance of HBsAg in the long run.
