Abstract:
Objective To investigate the risk factors of intrauterine hepatitis B virus (HBV)infection and its preventive measures.Methods 254 cases of pregnant women with positive HBsAg and their neonatuses from Shaanxi People’s Hospi-tal were selected as the research object.The serum of pregnant women were tested HBV markers and HBV-DNA,their neo-natal umbilical cord blood were only detected HBV markers.Results In 254 samples,the positive rates of HBsAg and HBeAg within their neonatal umbilical cord blood were 5.12% and 13.78% respectively;the positive rate of HBV infection in neonatal umbilical cord blood among maternal HBeAg-positive group was 53.33%,far higher than 3.61% in HBeAg-neg-ative group (χ2 =99.44,P <0.001);the positive rates of HBsAg and HBeAg in neonatal umbilical cord blood were elevated along with the increase of maternal HBV-DNA copy (Hc= 13.50,66.70;P < 0.001).The positive rate of HBV-DNA in pregnant women with HBeAg-positive group was 100%,far more than 19.59% in HBeAg-negative group (P <0.001).Con-clusion Both maternal positive HBeAg and HBV-DNA are risk factors for neonatal intrauterine HBV infection.Prenatal HBeAg screening is predominant,especially in some hospitals without real-time quantitative assay.An effective measure to reduce intrauterine HBV infection is to be pregnant when HBV DNA and HBeAg are turned into negative after HBV inter-vention and treatment for women in reproductive age.
