摘要 目的探讨HBV DNA对测定对HBsAg阴性慢性乙型肝炎(隐匿性乙型肝炎)的临床意义。方法对83例HBsAg阴性的慢性乙型肝炎HBV感染患者用酶联免疫检测法检测HBVM(HBsAg、抗-HBs、HBeAg、抗-HBe、抗-HBc),同时采用PCR技术对血清HBV DNA进行定量分析。对照组为同期经典的慢性乙型肝炎患者。结果83例HBsAg阴性慢性乙型肝炎患者中,HBV DNA阳性率为28.9%,单独抗-HBs阳性的慢性肝炎组HBV DNA阳性率为27.3%,抗-HBe,抗-HBc并存者HBV DNA阳性率为24%,抗-HBs、抗-HBe及抗-HBc三者阳性的慢性乙型肝炎患者HBV DNA阳性率为35%。单一的抗-HBc阳性的慢性乙型肝炎组HBV DNA阳性率为25%,HBeAg、抗-HBc阳性者HBV DNA阳性率为66.7%。结论HBsAg阴性HBV感染仍是我国原因不明肝病的主要原因之一,也是乙型肝炎疫苗接种无应答的原因之一,临床应重视这种低水平的HBV复制,以免造成宫内输血及肝移植后HBV感染。
