目的研究HbsAg阳性孕妇晚期妊娠应用乙肝免疫球蛋白(HBIG)对HBV宫内传播的阻断作用及孕妇血清HBV-DNA水平与宫内感染的关系。方法选择2007年6月至2009年6月在我院门诊产检及住院分娩的慢性乙肝孕妇及其新生儿317例,根据荧光免疫定量和ELISA法检测结果分为4组:A组HbsAg(+)、HbeAg(+)、HbcAb(+)、HBV-DNA低水平(≤103cp/mL)组;B组HbsAg(+)、HbeAb(+)、HbcAb(+)、HBV-DNA低水平(≤103cp/mL)组;C组HbsAg(+)、HbeAg(+)、HbcAb(+)、HBV-DNA中高水平(≥104cp/mL)组;D组HbsAg(+)、HbeAb(+)、HbcAb(+)、HBV-DNA中高水平(≥104cp/mL)组。在妊娠第28、32、36周各肌注乙肝免疫球蛋白(HBIG)400IU,新生儿于生后24h常规注射HBIG100U,并与于出生后0、1、6个月常规接种乙肝疫苗,检测新生儿脐血及出生后6个月、1年外周血乙肝抗原抗体六项。结果妊娠晚期应用乙肝免疫球蛋白后宫内感染发生率为7.07%。结论妊娠晚期应用HBIG可以降低宫内感染发生率,HBIG阻断乙肝病毒感染在HBV-DNA低水平组效果比HBV-DNA中高水平组好。
Objective To investigate the effect of antepartum injection of hepatitis B immunoglobulin on blocking the motherto-infant transmission of HBV and the relation between intrauterine infection and the DNA level of HBV in blood serum.Methods 317 pregnant women of chronic HBV carrier were devided into four group accroding to the fluorescence immunoassay and ELISA.A group HbsAg(+)、HbeAg(+)、HbcAb(+)、lower level HBV-DNA(≤103cp/mL),B group HbsAg(+)、HbeAb(+)、HbcAb(+)、lower level HBVDNA(≤103cp/mL),C group HbsAg(+)、HbeAg(+)、HbcAb(+)、higher level HBV-DNA(≥104cp/mL),D group HbsAg(+)、HbeAb(+)、HbcAb(+)、higher level HBV-DNA(≥104cp/mL).Pregnant women accepted injection of HBIG 400IU after conception 28,32,36 weeks and infant accepted injection of HBIG 100IU in 24 hours after borning,then accepted injection of HBV vaccinum 0,1,6 months after borning.The AG and AB of HBV were detected from infant blood.Results The rate of intrauterine infection is 7.07% after injecting HBIG during antepartum.Conclusion The injection of HBIG during anterpartum reduce the rate of intranterine infection,the effects of blocking more predominance in the lower level of HBV DNA than the higher level of HBV DNA.
