母婴传播是乙型肝炎(乙肝)传播的重要途径之一,据估计乙肝母婴传播率为40～50％。目前高效价免疫球蛋白(抗 HBs 的 PHA 滴度1:10,000以上)阻断乙肝母婴传播效果约71％。本文报道用中效价免疫球蛋白,阻断乙肝母婴传播的2年效果达72％.
Mother-to-child transmission is an important route for the spread of hepatitis B (hepatitis B). The estimated rate of mother-to-child transmission of hepatitis B is 40-50%. At present, high-titer immunoglobulin (anti-HBs PHA titer of 1: 10,000 or more) blocks about 71% of hepatitis B virus transmission. This article reports that in the titer of immunoglobulin, hepatitis B block mother-child transmission of 2-year effect of up to 72%.
