婴幼儿及学龄前儿童肺炎支原体肺炎临床特点分析

Clinical characteristics of mycoplasma pneumoniae pneumonia(MPP)in infants and preschool children

目的探讨婴幼儿及学龄前儿童肺炎支原体肺炎(MPP)的临床特点。方法以68例MPP患儿为研究对象,分为婴幼儿组(30例)和学龄前组(38例),对其临床资料进行回顾性分析。结果 2组发热、热程差异不明显(P>0.05),但是持续干咳、喘鸣和湿啰音差异有统计学意义(P<0.01)。学龄前组MP-Ig M滴度≥1∶160明显高于婴幼儿组(P<0.05);2组X线下小叶实质浸润和肺段实质浸润差异有统计学意义(P<0.05)。学龄前组肺外症状者率(26.3%,10/38)高于婴幼儿组(6.7%,2/30)。结论婴幼儿肺炎支原体肺炎症状较隐匿,实验室检查敏感性较低,临床治疗中应予充分重视,防止误诊或漏诊。

Objective To investigate the clinical characteristics of MPP in infants and preschool children. Methods 68 children with MPP were divided into infants group （30 cases）and preschool group（38 cases）.The clinical data were analyzed retrospectively.Results The difference of fever,fever duration between two groups was not significant,but in dry cough,wheezing rales and differences,the differences was statistical（P〈0.01 ）.The preschool group was significantly higher than infants in the titer of MP-IgM ≥ 1 ： 160 （P〈0.05）.The rate of extrapulmonary symptoms in the preschool group （26.3%, 10/38）was higher than that in the infants group （6.7% ,2/30）.Conclusion The symptoms of MPP in infants are relatively occult, and the sensitivity of laboratory tests is low.In clinical treatment,it should be paid full attention to prevent misdiagnosis or missed diagnosis.
