摘要目的 了解北京地区婴儿期生后巨细胞病毒(cytomegalovlrus,CMV)感染状况及其对婴儿生长发育的影响.方法 2004年11月至2008年3月北京市4家医院联合进行了孕妇、新生儿和婴儿CMV感染的多中心队列研究.本文选取非先天性CMV感染婴儿210例,检测1岁龄婴儿血清CMV IgG.根据婴儿12周龄尿CMV DNA结果和1岁龄CMV IgG结果,将婴儿分为围产期CMV感染组、婴儿期生后CMV感染组和非感染组.收集母婴相关资料并检查婴儿1岁时的生长发育状况、智测、眼睛和听力,对3组婴儿的新生儿期状况、1岁龄的生长发育进行比较,对影响婴儿期生后CMV感染的危险因素进行了非条件Logistic多因素回归分析.结果 210例婴儿中围产期CMV感染42例、婴儿期生后CMV感染98例、非感染70例,婴儿期生后CMV感染率46.40%,结合前期先天性感染、围产期感染结果,婴儿1岁龄时CMV总感染率为66.85%.3组婴儿出生时与1岁龄时的临床表现、生长发育和总发育商比较差异均无统计学意义;要儿期生后CMV感染组中母乳喂养、混合喂养和人工喂养的比例分别为87.76%、9.18%和3.06%,非感染组为61.43%、21.43%和17.14%(χ~2=17.040,P<0.01).结论 我国婴儿CMV感染非常普遍,非母乳喂养是婴儿期生后CMV感染的重要保护因素.婴儿期生后CMV感染对婴儿的健康和发育没有见到明显的不良影响.

abstractsObjective To understand the situation of postnatal cytomegalovirus (CMV) infection in Beijing and its impact on infant. Methods From November 2004 to March 2008, a multicenter cohort study on mammal, neonatal and infantile CMV infection was carried out in four hospitals in Beijing. Two hundred and ten infants without congenital infections were enrolled into this study. Their serum IgG antibody to CMV was determined at the age of 1 year. According to the results of CMV DNA at 12 weeks of age and the CMV IgG results at 1 year of age, they were divided into three groups, perinatal infection group, postnatal infection group and postnatal non-infection group. The information of their mothers, the data of their growth and development at 1 year of age, development quotient, their eyes and their auditory function were analyzed. The risk factors of the postnatal cytomegalovirus infection were analyzed by multi-factorial logistic regression. Results Of the 210 infants, 42 had perinatal infection, 98 had postnatal infection and 70 had no infection. The postnatal cytomegalovirus infection rate was 46.40%, taken into account the congenital infection rate and perinatal infection rote, the total cytomegalovirus infection rote was 66.85% at 1 year of age. The clinical manifestation, developmental status and the quotient of development from three groups at birth and at 1 year of age were analyzed. No significant difference was found. In postnatal cytomegalovirus infection group the rates of breast feeding, mixed feeding and formula feeding were 87.76%, 9.18% and 3.06%, respectively; while in no infection group the rates were 61.43%, 21.43% and 17.14%, respectively(χ~2 = 17.040, P <0.01). Conclusion CMV infection is present widely in China. Non-breast feeding is an important protective factor. Postnatal cytomegalovirus infection in infants had no significant impact on the health and development of infants.
