摘要 目的探讨乙型肝炎病毒前S1抗原(Pre-S1)与乙型肝炎病毒e抗原(HBeAg)、乙型肝癌病毒DNA(HBV-DNA)的关系。方法采用ELISA方法检测192例表面抗原阳性标本的Pre-S1抗原和乙肝"两对半",荧光定量PCR法检测HBV-DNA。结果200例乙肝表面e抗原(HBeAg)阳性患者血清中前S1抗原阳性率89.5%,HBV-DNA阳性率92.0%;280例乙肝e抗体(抗-HBe)阳性患者血清中前Sl抗原阳性率42.9%,HBV-DNA阳性率32.1%;100例HBeAg和抗-HBe均为阴性乙肝患者中前Sl抗原阳性率27.0%,HBV-DNA阳性率23.0%。P>0.05,差异无统计学意义,前Sl抗原与HBV-DNA总符合率为93.1%。在HBV-DNA的低拷贝(103-106copies/ml)中,前S1抗原的阳性率要明显高于HBeAg的阳性率,差异具有统计学意义(P<0.05)。结论前S1蛋白能够较好地反映乙肝病毒的复制情况,与HB-VeAg、HBV-DNA呈正相关,对病情的预后和疗效判断具有很好的临床应用价值。
