RESUMO
【Objective】 To study the risk factors of Hepatitis B Virus intrauterine transmission. 【Method】 Cordal blood from 87 HBV carrier's newborns was tested for HBV markers and PCR-HBV-DNA. Maternal venous blood po stpartum was tested for HBV markers. 【Results】 HBV-DNA positive rate of corda l blood is 1.2%(1/86). Odds Ratio(OR) of positive maternal HBsAb, HBeAg, HBeAb and HBcAb for intrauterine infection are 0.697(0.586～0.786), 50.792(13.082 ～197.204), 0.103(0.032～0.338) and 2.261(0.587～8.712), respectively. Co rdal HBsAg positive rate of maternal HBeAg positive group was significantly high er than that of only HBsAg positive group (31.0% vs 3.92%), so was cordal HBeA g positive rate (72.4% vs 3.92%). Maternal HBeAg was significantly correla ted with cordal HBsAg, especially HBeAg. Newborn sex wasn′t correlated with intraut erine infection. 【Conclusion】 Positive maternal HBeAg was one risk factor of i ntrauterine HBV infection. Newborn sex wasn′t correlated with intrauterine infe ction.
