Abstract

We evaluated the efficacy and safety of telbivudine (LdT, 600 mg/day) vs control patients (no treatment) in decreasing vertical transmission of HBV, in HBeAg-positive mothers (HBVDNA >6log(10) copies/mL). HBeAg-positive pregnant women either in the second or third trimester were recruited in a prospective, case-control, open-label study, at the Second Affiliated Hospital of the Southeast University, China (February 2008-December 2010). Efficacy (month 7: HBVDNA (+), HBsAg (+) infants) in either the overall group or the treated group and control group was analysed using student's t-test. Infants were followed for at least 1 year. 362 women received LdT (second trimester n = 257; third trimester n = 105) and 92 were untreated. Before delivery, the mean maternal HBVDNA was 2.73, 2.47, 3.34 and 7.94 log10 copies/mL in the overall, second and third trimester treated and control groups, respectively (P < 0.001). At birth, 11.8% of babies overall (43/365), 13.5% (35/259) of those treated in the second trimester, 7.5% of those treated in the third trimester (8/106) and 20.7% (19/92) of untreated infants were HBsAg positive. At month 7, none of the LdT-treated infant had detectable HBVDNA, while eight infants from control mothers were HBsAg positive. Vertical transmission was 0% in LdT treated and 9.3% (8/86) in the control groups (P < 0.001). No difference in the vertical transmission rate was found in mothers treated in the second or third trimester. LdT treatment was safe for mothers and infants, and no congenital deformities were reported.
