长沙地区母婴HCMV感染的分子流行病学初步研究

利用ELISA及PCR技术对长沙地区 12 5对母、婴HCMV IgG ,IgM及HCMV DNA进行了检测。结果显示 :在 12 5对母、婴中 ,HCMV IgG阳性率分别为 95 .2 % (119/ 12 5 )和 93.6 % (117/ 12 5 ) ,HCMV IgM阳性率分别为 5 .6 % (7/12 5 )和 0 .8% (1/ 12 5 ) ,血浆HCMVDNA阳性率分别为 11.2 % (14/ 12 5 )和 5 .6 % (7/ 12 5 ) ,P(C)BMCsHCMVDNA阳性率分别为 2 1.6 % (2 7/ 12 5 )和 14.4% (18/ 12 5 )。新生儿CBMCS HCMVDNA阳性率显著高于HCMV IgM及血浆HCMVDNA的阳性率 (P <0 .0 5 ) ,而血浆PCR与IgM阳性率差异无显著性意义 (P >0 .0 5 )。新生儿CBMCSHCMVDNA用于判断其先天性感染的灵敏度为 81.8%。表明CBMCSHCMVDNA与血浆HCMV IgG分别为新生儿及产妇HCMV感染的较好的流行病学指标。

Study on molecular epidemiology of HCMV infection in mothers and their newborns in Changsha

The detection of HCMV-IgG,IgM in plasma by ELISA and DNA inplasma and P(C)BMCs from mothers and their newborns by PCR was carried out. Positive HCMV-IgG, HCMV-IgM,P(C)BMCs HCMV DNA and plasma HCMV DNA were demonstrated in 119(95.2%),7(5.6%),27(21.6%)and 14(11.2%) in 125 mothers and 117(93.6%), 1(0.8%),18(14.4%) and 7(5.6%) in their mewborns, respectively. There were significant differences among the positive rate of newborn's HCMV-IgM, plasma HCMV DNA and CBMCs HCMV DNA (P＜0.05)，but the difference between HCMV-IgM and plasma HCMV DNA had no statistic significance(P＞0.05). This study suggests that HCMV-IgG and CBMCs HCMV PCR are preferable epidemiological index of HCMV infection of pregnant women and newborns respectively.
