孕晚期注射乙型肝炎免疫球蛋白阻断乙型肝炎宫内感染临床观察

Clinical observation of the HBIG to prevent the hepatitis B infection during late pregnancy

目的观察乙肝免疫球蛋白在妊娠晚期注射阻断乙型肝炎宫内感染的临床效果。方法对68例HBsAg(+)孕妇,其中有18例HBeAg(+),自孕28周开始每4周肌内注射乙型肝炎免疫球蛋白(HBIG)200IU,分娩后新生儿采脐血5ml,检测乙肝病毒标记物(HBVM)。结果68例新生儿脐血HBsAg阳性者占10.3%,其中HBsAg、HBeAg双阳性者占5.9%。50例仅HBsAg阳性孕妇所生新生儿脐血HBsAg阳性率为4%(2/50),18例HBsAg、HBeAg双阳性孕妇所生新生儿脐血HB-sAg阳性率为27.8%(5/18),两者比较差异有统计学意义。结论HBsAg(+)孕妇孕晚期注射HBIG,阻断宫内HBV感染的效果显著;HBeAg(+)孕妇宫内感染的危险性较大。

Objective To observe the HBIG clinic result during late pregnancy period preventing the hepatitis B infection.Methods 68 HbsAg(+)pregnant women,including HBeAg(+)18 case were injected for 200 IU HBIG,at 28 weeks from pregnancy once every 4 weeks,after delivery infant cord blood 5 ml collected,and the HBVM checked.Results The HBsAg positive rate is 10.3% in these 68 infants,within them and the HBsAg and HBeAg positive rate is 5.9%.The positive rate of the infants from 50 HBsAg positive pregnancy women is only 4%(2/50),while the positive rate of the infants from 18 HBsAg and HBeAg positive is 27.8%(5/18),there are great different between two groups.Conclusion It is greatly effective in late pregnant period to inject HBIG preventing HBV infection.The danger for HBeAg(+)pregnant women is much larger.
