We studied the effect of Sho-saiko-to (Xiao-Chai-Hu-Tang) on HBeAg clearance rate (SN rate) in fourteen children with chronic hepatitis B virus (HBV) infection and with sustained liver disease. Seven of fourteen patients (50.0%) became HBeAg negative in the average observation period of 0.47 years(0.2-0.9 years). Four of those seven patients developed anti-HBe. The annual SN rate in the She-saiko-to treated group was apparently higher than the natural annual SN rate (22.7%) of 22 untreated patients retrospectively reviewed from the onset of hepatitis. Sho-saiko-to seemed to promote clearance of HBeAg in children with chronic HBV infection and with sustained liver disease. Sho-saiko-to may be an useful drug for such patients.
