The efficacy of antiviral therapy,mothers or their infants complications,the risk of perinatal transmission of HBV infection were observed. Results In lamivudine-treated group, serum HBV-DNA was not detected in 85.71%(36/42). Normalization of liver function was achieved in 88. 10% (37/42). Severe hepatitis B was not oc-cured,the rates of mothers or their infants complications and HBV perinatal transmission were also decreased obviously. Compared with control group,the differences were statistically significant(P <0. 05). Conclusions Lamivudine in the treatment of chronic hepatitis B during pregnancy was safe and effective,and conduced to improve the curative effect in treatment of chronic hepatitis B, and reduced mothers or their infants complications and HBV perinatal transmission.
