Abstract:
To investigate the impact of maternal hepatitis B virus (HBV) carrier state on twin pregnancy outcomes. Methods From January 2004 to December 2012, 569 women with twin pregnancy were hospitalized in Nanjing Drum Tower Hospital. Thirty-two women positive for hepatitis B surface antigen (HBsAg)(negative for hepatitis B e antigen, with normal liver function before conception)were included in the HBsAg-positive group and the other 537 women were included in the HBsAg-negative group. The pregnancy outcomes of the two groups were compared by t test and Chi-square test. The risk factors for neonatal birth weight were analyzed by multivariate regression analysis. Results Compared with the HBsAg-negative group, the HBsAg-positive women had a higher incidence of abnormal liver function (alanine aminotransferase≥50 U/L) [18.8% (6/32) vs 5.8% (31/537), χ2=6.367, P=0.012]. The incidence of gestational diabetes mellitus was 21.9% (7/32) in the HBsAg-positive group, which was higher than in the HBsAg-negative group [11.6% (62/537)], although the difference was not significant (χ2=2.132, P=0.144). The incidences of intrahepatic cholestasis of pregnancy,hypertensive disorders complicating pregnancy, premature rupture of membranes, placenta previa, fetal distress, postpartum hemorrhage, preterm birth, caesarean section, umbilical cord around the neck, meconium-staining amniotic fluid and neonatal asphyxia were no statistical difference between two groups (all P<0.05, respectively). Multivariate regression analysis showed that gestational diabetes mellitus (β=67.869, 95%CI: 0.494-135.244, P=0.048), maternal age (β=6.592, 95%CI: 2.020-11.880, P=0.006) and gestational age (β=164.069, 95%CI:154.426-173.712, P<0.01) were risk factors for neonatal birth weight, but not the maternal HBsAg-positive status (β=78.864, 95%CI: -16.950-174.678, P=0.107). Conclusion Twin pregnancy and HBV carrier state increase the risk of abnormal liver function, but not other adverse pregnancy outcomes and newborn diseases.
