摘要 目的通过对乙型肝炎患者血清前S1抗原(Pre-S1Ag)的检测,了解乙肝患者在HBeAg阴性时,Pre-S1Ag的阴阳情况,以及Pre-S1Ag与HBV-DNA的相关关系。方法收集本院门诊及住院乙型病毒性肝炎患者HBeAg阴性血清164例,HBeAg阳性81例,均经临床确诊,用酶联免疫吸附法检测了Pre-S1Ag,同时用PCR法检测了HBV-DNA。结果HBeAg阴性的164例中Pre-S1Ag的阳性例数为28例,阳性率17.1%(28/164),HBV-DNA的阳性例数为36例,阳性率22.0%(36/164),两者χ2=1.24,P>0.05。HBeAg阳性的81例标本中,Pre-S1Ag的阳性例数为62例,阳性率76.5%(62/81)HBV-DNA的阳性例数为63例,阳性率77.8%(63/81),两者χ2=0.04,P>0.05。99例HBV-DNA阳性的乙肝患者中Pre-S1Ag阳性89例,146例HBV-DNA阴性的患者中,Pre-S1Ag阴性145例,阳性1例,二者χ2=0.7,P>0.05,无明显性差异。结论HBeAg阴性的乙肝患者中有部分乙肝病毒在不断复制;Pre-S1Ag及HBV-DNA都是协助诊断乙肝病毒复制的有用指标。特别是无条件开展PCR的单位,Pre-S1Ag的检测同样可反映乙肝病毒复制的情况。特别在HBeAg阴性时,病毒仍有复制,对临床判断慢性乙肝病情与指导治疗都有一定临床价值,且操作简单、方便,易推广应用。
