930例呼吸道感染患儿肺炎支原体IgM抗体的结果分析

Analysis on the results of IgM antibody of Mycoplasma pneumoniae in children with respiratory tract infection in 930 cases

目的通过检测及分析患儿血清中肺炎支原体IgM抗体，探讨患儿肺炎支原体感染的流行病学特征。方法应用ELISA原理定性检测患儿血清中的肺炎支原体IgM抗体，采用X^2检验对不同性别、季节及年龄的数据进行分析。结果共检测患儿标本930例，阳性例数为334例，总阳性率为36％。其中男性患儿阳性率为30．7％，女性患儿阳性率为43．9％。春夏秋冬四季的阳性率分别为33％、34％、36％及40％。O～1岁、1～3岁、3～6岁及〉6岁患儿阳性率分别为19％、33％、43％及51％。结论女性患儿肺炎支原体感染率明显高于男性患儿（P〈O．05）；秋冬季节肺炎支原体感染率较高，但四季之间没有明显的统计学差异（P〉O．05）；0-1岁的患儿阳性率最低，6—14岁的患儿阳性率最高，且年龄分组之间有显著的统计学差异（P〈0．05）。

Objective To explore the epidemiological characteristics of Mycoplasma pneumoniae infection in children by detecting and analyzing the IgM antibodies in serum of children with Myeoplasma pneumoniae. Methods the ELISA principle was used to detect the serum Myeoplasma pneumoniae IgM antibody, and the Z2 test was used to analyze the data of different sex,age and season. Results a total of 930 cases were detected,the number of positive cases was 334 cases,the total positive rate was 36 %. The positive rate was 30.7% in male and 43.9% in female. The positive rates were 33% ,34% ,36% ,40% and respectively in the four seasons of spring and summer. 0-1 years old, 1-3 years old, 3-6 years old and 〉6 years old children positive rates were 19 %, 33 %,43% and 51%.Conclusion female children with Mycoplasma pneumoniae infection rate was significantly higher than that of male patients （P〈0. 05） was higher in autumn and winter; Mycoplasma pneumoniae infection, but no statistically significant difference between seasons （P〉0. 05）; the positive rate of children aged 0-1 minimum,the positive rate of children 6-14 years old age group between the highest,and there was a statistically significant difference （P〈0. 05）.
