目的：探讨哮喘患儿肺炎衣原体(chlamydia pneumoniae，CP)及肺炎支原体(mycoplasma pneumoniae，MP)感染的临床特征。方法：选取2013年1月至2016年1月在我院治疗的哮喘急性发作患儿80例，其中CP感染41例，MP感染39例，分析CP及MP感染的临床特征。结果：CP及MP感染有相似的临床症状，常见症状包括头痛、流鼻涕、咳嗽、发热等。其中CP感染引起的呕吐和腹泻情况多于MP感染(P<0.05)；MP感染引起的胸腔积液多于CP感染(P<0.05)；CP感染中1岁以下患儿41.46%，而MP感染中4岁以上的患儿56.41%；CP感染中病程≤3个月48.78%，MP感染中病程>6个月46.15%；CP感染患者CD3+，CD3+CD4+，CD19+和CD4+CD25+明显低于MP感染(P<0.05)。结论：临床特征对哮喘急性发作患儿CP及MP感染的诊断可提供参考，有助于早期诊断。
Clinical characteristics of chlamydia pneumoniae and mycoplasma pneumoniae infection in asthma children
Objective: To investigate clinical characteristics of chlamydia pneumoniae (CP) and mycoplasma pneumoniae (MP) infection in acute asthma children. Methods: From January 2013 to January 2016, selected 80 cases of acute asthma children adopted in our hospital, including 41 cases of CP infection, 39 cases of MP infection, analyzed the clinical features of CP and MP infection. Results: CP and MP infection had similar clinical symptoms including headache, runny nose, cough, fever, etc. Vomiting and diarrhea caused by CP infection was more than by MP infection (P<0.05); The pleural effusion caused by MP infection was more than by CP infection (P<0.05); CP infection in children under 1 year old was 41.46%, and MP infection in children over 4 years of age, the proportion was 56.41%; The proportion of course of disease >3 months in CP infection was 48.78%, the proportion of course of disease >6 months in MP infection was 46.15%; CD3+, CD3+CD4+, CD19+ and CD4+CD25+ levels in CP infection patients were significantly higher than those in MP infected patients (P<0.05). Conclusion: Clinical characteristics can provide reference for the diagnosis of CP and MP infection in acute asthma children, and contribute to early diagnosis.
