Abstract
目的 荧光定量PCR检测乙肝患者血清的HBVDNA含量,并探讨及其对临床意义.方法对520例怀疑乙肝患者的血清进行ELISA法检测乙肝病毒血清标志物(HBVM)和荧光量聚合酶链反应(FQ-PCR)检测HBVDNA的含量并进行比较.结果检测的520例血清标本中HBVDNA水平在不同乙型肝炎类型中显著性差异(P>0.05),与HBV-M主要阳性模式组对比,在135阳性组HBVDNA的阳性率为97.7%(164/168),1 3模式组阳性率为100%(20/20),145模式组阳性率为55.56%(15/27),在检测的全阴性的模式组中有一例DNA阳性为5.88%(1/17).结论HBVDNA的含量在不同的阳性模式中均不同程度地检测出HBVDNA的含量.其中,HBeAg阳性血清标志物中HBVDNA的检测率最高几乎达到100%.采用简单快捷的荧光定量PCR检测对乙肝患者的带毒状态进行准确判断.但HBVDNA的复制状态与不同临床类型乙型肝炎无明显相关关系,HBVDNA含量高低与肝功能的损害程度亦无明显关系。
