摘要
目的评价套式聚合酶链反应技术(NT-PCR)加限制酶分析在孕妇与胎儿人巨细胞病毒(HCMV)感染检测中的应用价值。方法应用NT-PCR及限制酶分析、病毒分离、电镜观察和特异性抗体测定,对各孕期孕妇367例的外周血、部分孕妇脐血及死胎组织进行HCMV检测。结果孕早、中、晚期HCMV阳性检出率分别为8.6%、1.6%及7.0%,NT-PCR检出率(4.9%)高于病毒分离(3.0%,P<0.025)。6份HCMVDNA阳性母血中,3份配对脐血HCMVDNA也阳性。其中2对NT-PCR、病毒分离及特异性IgM、IgA均阳性,1对NT-PCR、病毒分离、特异性IgA阳性,而IgM阴性。28例死胎组织中,发现1例死胎肺组织HCMVDNA阳性。
Objectives To evaluate the applicability of nested polymerase chain reaction (PCR) and restriction endonucleases analyses (REA) for the diagnosis of human cytomegalovirus (HCMV) in pregnant women and their fetuses. Methods Nested PCR and REA, virus isolation, anti HCMV IgM and anti HCMV IgA were used for detection of HCMV in peripheral blood of pregnant women, umbilical blood and tissues of stillbirths. Results among 367 pregnant women, the HCMV infections rate in the first, second and third trimester of gestation were 8.6%, 1.6% and 7.0%, respectively. The nested PCR had significantly higher detective rate (4.9%) than that of virus isolation (3.0%, P <0.025). Among 6 samples of maternal HCMV DNA positive blood, 3 matched umbilical samples were HCMV DNA positive as well. Of these 3 cases, HCMV intrauterine infection was considered. HCMV was detected with all measurements in both maternal and umbilical blood except in 1 paired samples specific IgM were negative. HCMV DNA was found in the lung tissue of one of the 28 stillbirths. Conclusion the diagnostic specificity and sensitivity of HCMV can be raised by nested PCR.
