A higher rate of adverse pregnancy outcome in HBsAg-positive pregnant woman

Abstract Objective The aim of this study was to study the relationship between adverse pregnant outcomes(APO) with chronic hepatitis B virus (HBV) infection in pregnant women. Method From 2017 to 2019, we studied HBsAg (+) pregnant women and HBsAg (-) who gave birth at our hospital in Guangzhou City, China. We compared of the outcomes of pregnant women with HBsAg(+) or HBsAg(-). Further, among HBsAg(+) pregnant women, We compared of the outcomes of pregnant women with HBeAg(+) group or HBeAg(-) group, HBV DNA above 2×10e5IU/mL group or HBV DNA below 2×10e5IU/mL) group, respectively. Finally, multivariate logistic regression analysis was used to evaluate the independent association between HBV infection and the risk of developing APO. Result First, Our research Indicates that the rates of gestational diabetes mellitus (GDM), intrahepatic cholestasis of pregnancy (ICP), premature rupture of membrane (PROM), Fetal distress (FD), Oligohydramnios, Premature delivery (PD), Low birth weight (LBW), Meconium contamination (MC), Neonatal hyperbilirubinemia(NH) in HBsAg(+) group were higher than those in HBsAg(-) group (P<0.05). Second, among 711 HBsAg(+) pregnant women, the rates of GDM and ICP in HBV DNA above 2ⅹ10e5 IU/mL were higher than those in HBV DNA below 2×10e5 IU/mL group (P<0.05). Similarly, The rates of ICP in HBeAg(+) group were higher than those in HBeAg(-) group. Further, through multivariable logistical regression model analysis, we observed maternal HBsAg carrier (OR, 6.758; 95% CI, 2.358-19.369) had an independent risk for ICP. Similarly, HBsAg carrier(OR, 1.101; 95% CI, 1.066-1.137) ,advanced age (OR, 1.407; 95% CI,1.033-1.917) and abortion(OR,1.446; 95% CI, 1.062-1.969) had independent risk for GDM. Conclusions Chronic HBV infection can increase the rate of host adverse pregnancy outcomes (APO). The maternal viral load and HBeAg status were significantly associated with the appearance of GDM and ICP. Maternal HBsAg carrier had an independent risk for GDM and ICP.
