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 analyze the status of mycoplasma pneumoniae infection in 312 children with community-acquired pneumonia (CAP) in hospital and provide basis for clinical experience treatment. Methods: 312 cases of hospitalized children with CAP according to different age groups were divided into 4 groups, 4 groups of children with acute serum samples were tested for Mycoplasma pneumoniae IgM antibodies, Mycoplasma pneumoniae infection rates by age groups and different seasons compared . Results: The positive rate of Mycoplasma pneumoniae in 312 CAP patients was 62 (19.9%), of which the highest positive rate was 56.1% (32/57) in 7-year-old to 14-year-old group, followed by 49.2% (31/63). The infection rate was 14.8% (16/108) in patients aged 2 to 3 years and 5.9% (5/84) in 0 to 1 years. The infection rate in school-age children was significantly higher than that in preschool children Children; different season of Mycoplasma pneumoniae infection rate difference was not significant. Conclusion: Mycoplasma pneumoniae infection is more common in school-age children than in school-age children. The seasonal division is not obvious in this region.
