312例社区获得性肺炎住院患儿肺炎支原体感染状况分析

A study of mycoplasma infection in 312 cases of children's community acquired pneumonia

目的:分析312例儿童社区获得性肺炎(CAP)住院患儿病原中肺炎支原体感染状况,为临床经验性治疗提供依据。方法:对312例住院的CAP患儿按不同的年龄段分4组,4组患儿急性期血清标本均进行肺炎支原体IgM抗体检测,对肺炎支原体感染率按不同年龄组以及不同季节组进行比较。结果:312例CAP患儿肺炎支原体检测阳性62例(19.9%),其中7岁～14岁组阳性率最高,为56.1%(32/57);其次为4岁～6岁组,为49.2%(31/63);2岁～3岁组感染率为14.8%(16/108),0岁～1岁组感染率为5.9%(5/84),学龄期儿童感染率明显高于学龄前儿童;不同季节肺炎支原体的感染率差异不显著。结论:肺炎支原体感染在年龄分布上以学龄期儿童多见,季节分部在本地区不明显。

Objective：To investigate the mycoplasma infection in 312 cases of children＇s community acquired pneumonia（CAP）,to provide the clinical therapy experience.Methods：312 cases of children＇s community acquired pneumonia（CAP） were divided into four groups,the MP-IgM were detected,which infection rate were compared by different age and seasons.Results：The overall positive rate of mycoplasma IgM in 312 cases was 19.9%.The ratios of mycoplasma infection among the four groups were respectively 5.9%,14.8%,49.2% and 56.1%,showing significant differences between school-age and school-age prophase.Conclusion：The mycoplasma infection is closely related to school-age but season.
