目的:探讨儿童肺炎支原体(MP)感染的临床特点。方法:回顾性分析89例确诊为MP感染的儿童患者的临床资料。结果:本组患儿以婴幼儿为主,3岁以内42例(47%),3岁～5岁32例(36%),5岁以上15例(17%)。婴幼儿以发热、肺部表现为主,其中表现为喘息者18例(43%)。MP感染并发肺外表现者以年长儿多见,且主要损害神经、血液、泌尿、心血管、消化等系统,表现为脑炎、血小板减少性紫癜、急性肾炎、胸腔积液、心力衰竭及肝功能损害等。结论:儿童婴幼儿感染MP感染的发生率较高;不同年龄组的临床表现各异,有肺外表现者可涉及各个系统,提示对以喘息和肺外表现为主要临床表现的患儿,应警惕MP感染,以免延误治疗。
Objective: To investigate the clinical features of Mycoplasma pneumoniae (MP) infection in children. Methods: The clinical data of 89 children diagnosed as MP infection were retrospectively analyzed. Results: The infants in this group were mainly infants and young children. There were 42 cases (47%) within 3 years of age, 32 cases (36%) aged 3 to 5 years and 15 cases (17%) over 5 years old.

MP infection complicated by extrapulmonary manifestations in older children more common, and the main damage to nerve, blood, urinary, cardiovascular, digestive system, manifested as encephalitis, thrombocytopenic purpura, acute nephritis, pleural effusion, heart failure and Liver damage and so on. CONCLUSIONS: The incidence of MP infection in infants and young children is high; clinical manifestations vary among different age groups and individuals with extrapulmonary manifestations may be involved in various systems, suggesting that children with wheezing and extrapulmonary manifestations as the main clinical manifestation should be Be wary of MP infection to avoid delay treatment.
