摘要 目的:探讨HBV-DNA荧光定量、乙肝前S1抗原(PreS1)与HBV血清学标志物(HBVm)之间的相关性。方法:采用荧光定量PCR、酶联免疫吸附法(ELISA)对200份HBsAg阳性标本进行HBV-DNA、PreS1、HBVm检测。结果:在HBV-DNA荧光定量阳性的158份血清样本中(病毒载量大于103拷贝/ml)PreS1抗原的阳性率达到81.6%(129/158),并且血浆中HBV-DNA含量水平与PreS1抗原阳性检出率间存在显著相关性(P<0.001)。HBeAg阴性109份,HBV-DNA荧光定量阳性率64.2%;PreS1抗原阳性率48.6%。急性肝炎中HBV-DNA及PreS1的阳性检出率分别为96%和92%。在轻度慢性乙肝中,HBV-DNA及PreS1的阳性检出率分别为83.3%和70%。在此两类肝炎标本中HBV-DNA与PreS1的阳性检出率没有显著性差异(P>0.05)。而在中重度慢性乙肝及肝炎肝硬化标本中HBV-DNA的阳性检出率明显高于PreS1(P<0.01)。结论:PreS1可作为HBV-DNA荧光定量的有益补充用来判断病毒复制情况,对乙型肝炎诊断、疗效判断具有十分重要的意义。
