目的：探讨小儿支气管哮喘与反复呼吸道感染的相关性。方法收集在该院诊疗87例小儿支气管哮喘患者(试验组)及同期门诊体检儿童73例(对照组)作为研究对象，对所有患儿检测病毒、支原体衣原体以及细菌感染情况，并行对比分析。结果试验组患儿合并呼吸道感染占35．63%明显高于对照组的6．85%(P<0．01)。试验组呼吸道感染病原检出率为74．71%高于对照组24．66%，(P<0．01)；试验组病毒检出率为37．93%高于对照组12．33%( P <0．01)；试验组支原体、衣原体检出率为24．14%高于对照组9．59%(P<0．05)；试验组细菌检出率为12．64%高于对照组2．74%(P<0．05)。结论哮喘发作与反复呼吸道感染有密切相关性，呼吸道病毒感染、支原体、衣原体和细菌感染是小儿哮喘急性发作和加重的主要诱因。%Objective To explore the relationship between children with bronchial asthma and respiratory in-fections. Methods 87 children with asthma were selected as the observation group, and another 73 healthy children were taken as the control health group. Serum MP-IgM and CP-IgM were detected by the granule agglutinating method and indirect solid phase enzyme immunoassay ( EIA) respectively. Results There were 31 children with repetitive respiratory infection in the observation group (35. 63%), and there were 5 children with repetitive respiratory infec-tion in the control group ( 6. 85%) . The detection rate of pathogens was 74. 71% in the observation group, which was obviously higher than that in the control group (24. 66%). The positive rate of bacteria was 12. 64% in the ob-servation group, and 2. 74% in the control group ( P <0. 05 ) . Conclusion Asthma exacerbation in children is closely related to respiratory tract infections, which the main causes are MP and CP and bacteria infections.
