本文采用间接ELISA方法测定224例妊娠36周妇女及其中116例新生儿脐血CBV-IgM。其母血阳性率26.34％(59/224),脐血阳性率7.76％(7/116)母血阴性组165例的脐血均为阴性,母血阳性组有29例取脐血,有7例阳性。对其进行随访发现一例新生儿心电图ST改变及心肌酶异常,进一步证实了CBV可经胎盘感染胎儿。在母血和脐血阳性组的孕妇,在妊娠期间的上呼吸道感染等症状明显高于母血脐血阴性组。因此,妊娠期间除外其他感染的同时,进行CBV筛查是必要的。
In this paper, 224 cases of pregnant women and 36 weeks of neonatal CBV-IgM were measured by indirect ELISA. The positive rate of maternal blood was 26.34% (59/224). The positive rate of umbilical cord blood was 7.76% (7/116). The umbilical blood of 165 maternal negative patients was negative, while the positive maternal blood of 29 patients with umbilical cord blood and 7 Positive cases. The follow-up found a case of neonatal ECG ST changes and myocardial enzyme abnormalities, further confirmed that CBV can be placental infection in the fetus. In pregnant women with maternal blood and cord blood-positive group, symptoms such as upper respiratory tract infection during pregnancy were significantly higher than those in the maternal-cord blood-negative group. Therefore, in addition to other infections during pregnancy at the same time, screening for CBV is necessary.
