呼吸道感染患儿肺炎衣原体感染情况调查分析

Research on chlamydia pneumoniae infection in children with respiratory tract infection

目的探讨呼吸道感染患儿肺炎衣原体(CP)感染情况。方法选择本院住院呼吸道感染患儿5983例,应用酶联免疫吸附法(ELISA)检测其CP-IgM抗体。结果 5983例标本中共检出阳性413例,阳性率为6.90%。男、女性患儿肺炎衣原体抗体阳性率比较无统计学意义(P>0.05)。婴儿期、幼儿期、学龄前期、学龄期的阳性率为5.72%,7.04%,5.66%,21.86%,各年龄组间差异有统计学意义(P<0.01)。一年四季均可发病,阳性率分别为9.64%,3.70%,5.37%,6.89%,不同季节阳性检出率差异有统计学意义(P<0.01)。结论肺炎衣原体感染与年龄、季节有密切关系。7岁以上学龄期的儿童感染率高,春季多发。

Objective To investigate chlamydia pneumoniae infection in children with respiratory tract infection.Methods 5983 patients who were diagnosed respiratory tract infection were selected in our hospital, and enzyme-llnked immunosorbent assay （ELISA） was used to detect cblamydia pneumoniae antibodies （CP-IgM）.Results Among S983 samples, 413 cases were detected positive, positive rate was 6.90%. The difference between the male and female was not significant.The positive rate in the group of babyhood, toddler period, preschool period, school period was 5.72% ,7. 04%,5.66%, 21.86%, with significant differences among the different groups （P〈0.01 ）. The positive rate in spring, summer,autumn,and winter was 9.64%,3.70%, 5.37%, 6. 89%, with significant differences among the seasons（P〈0. 01）.Conclusion The incidence of CP is closely related to age and season.The children more than seven years old have the highest positive rate and the most common in spring.
