title: Lamivudine therapy in the treatment of chronic hepatitis B with acute exacerbation during pregnancy.
abstract: We report a case of chronic hepatitis B carrier gravida who had acute exacerbation during pregnancy. She had been taking lamivudine 100 mg/qd for 17 months when hepatitis B virus (HBV) DNA in the YMDD region of the polymerase gene (YMDD motif) mutant was noted. After discontinuing lamivudine, she became pregnant. HBeAg became positive again and liver enzymes were elevated during the first trimester of pregnancy. She received the hepatoprotective agent silymarin 150 mg bid at 13+2 gestational weeks. Serum aspartate aminotransferase (AST) dropped to 757 U/L at 15+0 gestational weeks, but serum alanine aminotransferase (ALT) flared up to 2,230 U/L and AST to 2,250 U/L at 17+1 gestational weeks. Serum HBV-DNA test revealed serum HBV-DNA concentration of 7.31 x 10(8) copies/mL. Lamivudine 100 mg/qd and silymarin 150 mg/bid were initiated at 17+1 gestational weeks. Liver function showed gradual decline to ALT 341 U/L and AST 91 U/L at 21+0 gestational weeks, while HBeAg(+) converted to (-) and anti-HBe(-) converted to (+). Further treatment with lamivudine 100 mg/qd continued for 3 months. Serum HBV-DNA concentrations decreased to 3.19 x 10(2) copies/mL at 36+6 gestational weeks. Spontaneous delivery of a male baby weighing 3314 g occurred at 38+3 gestational weeks. The neonatal physical check-up revealed no congenital anomalies, and fetal growth was within normal reference ranges, suggesting that lamivudine may be safely used in the treatment of chronic hepatitis B with acute exacerbation during the second trimester of pregnancy.
