1、根据乙肝表面抗原滴度注射不同剂量乙肝免疫球蛋白降低胎儿宫内感染率的研究作者:汪洪,郭晓玲,梁少联,陈咏涛,张国华,刘金凤【摘要】目的根据乙肝表面抗原滴度不同,注射不同剂量的乙肝免疫球蛋白,以降低高滴度HBsAg孕妇的宫内感染率的研究。方法选取XX年12月—XX年12月在本院系统产检分娩的乙肝表面抗原阳性的孕妇及其分娩的新生儿共385例为研究对象。孕妇于孕28周前抽取静脉血查HBsAg滴度、HBeAg及HBV-DNA,观察组170例孕妇于孕28周、32周、36周分别注射HBIG00IU,对照组215例同期注射HBIG00IU。两
2、组患者产后即时抽取胎儿脐血,查乙肝两对半及HBV-DNA,若HBsAg和HBeAg或HBV-DNA,确定为胎儿宫内感染。结果单纯低滴度HBsAg患者胎儿宫内感染率为11%,10%,差异无显著性;单纯高滴度HBsAg患者胎儿宫内感染率为9%,18%,差异有显著性;低滴度HBsAg合并HBeAg或HBV-DNA患者胎儿宫内感染率为13%,13%,差异无显著性;高滴度HBsAg合并HBeAg或HBV-DNA患者胎儿宫内感染率为15%,21%,差异有显著性。结论对HBsAg滴度较高的孕妇,尤其是合并HBeAg阳性或抗HBc阳性的孕妇,
