摘要 目的采用酶联免疫吸附试验(ELISA)和实时荧光定量聚合酶链反应(RT-PCR)检测手足口病患儿血清肠道病毒71型(EV-A71)IgM、柯萨奇病毒A16型(CV-A16)IgM和粪肠道病毒通用型(EV)、EV-A71、CV-A16型病毒RNA,并对检测结果进行比较分析。方法采用ELISA检测对2596例手足口病患儿血清EV-A71IgM、CV-A16IgM,采用RT-PCR检测粪便或肛拭子标本中EV-RNA、EV-A71RNA、CV-A16RNA。结果2596例患儿中EV-A71IgM、EV-A71RNA、CV-A16IgM、CV-A16RNA阳性分别为367例(14.1%)、50例(1.9%)、320例(12.3%)、91例(3.5%)。ELISA和RT-PCR检测EV-A71差异有统计学意义(P<0.01),且两种方法一致性较差(P<0.01);检测CV-A16差异有统计学意义(P<0.01),且一致性较差(P<0.01)。EV-RNA阳性2296例(88.4%),EV-A71IgM和CV-A16IgM双阳性137例(5.3%),EV-A71RNA和CV-A16RNA双阳性0例(0.0%)。结论手足口病患儿进行EV-A71和CV-A16检测,ELISA血清学检测阳性率高于RT-PCR粪便中核酸检测,且两种方法一致性较差。
