母体乙型肝炎表面抗原阳性者所生新生儿有垂直传播病毒感染的危险,日后可发生抗原血症性肝炎、肝硬化、肝癌。在高发地区如东方,有40%新生儿的乙型肝炎可能系围产期病毒垂直传播的结果。作者为在全国进行筛查前确定乙型肝炎对妊娠结果的影响,将某大学医院产科自1983年所有产前检查孕妇,常规进行放免测定乙型肝炎表面抗原筛 Newborn babies born with positive HBsAg are at risk for transmission of the virus vertically and may develop antihepatitis, cirrhosis, and liver cancer in the future. In high incidence areas such as the East, 40% of newborns with hepatitis B may be the result of vertical transmission of perinatal virus. The authors determine the impact of hepatitis B on pregnancy outcomes prior to screening across the country.
