小儿支原体肺炎并发反复性呼吸道感染的临床因素分析及评价

Analysis and evaluation of clinical factors of mycoplasma pneumonia complicated with recurrent respiratory tract infection in children

目的分析与评价小儿支原体肺炎并发反复性呼吸道感染的临床因素。方法选取某院2014年5月至2015年6月收治的160例小儿支原体肺炎并发反复性呼吸道感染患者为研究组，另选同期160例小儿支原体肺炎患者为对照组，分析诱发支原体肺炎并发反复性呼吸道感染的临床因素。结果通过对比发现，中性粒细胞减少症、支原体抗体持续阳性、嗜酸细胞增多、年龄、免疫指标为其支原体肺炎并发反复性呼吸道感染的单一临床因素；多元logistic回归分析结果显示，年龄4～6岁、抗体持续阳性、粒细胞减少、嗜酸细胞增多、CD4／CD8降低、IgA水平低下为其独立风险因素（P〈0．05）。结论支原体肺炎并发反复性呼吸道感染的独立风险因素较多，需要引起临床医务人员的足够重视以降低该病症发生几率。

Objective To analyze and evaluate clinical factors of mycoplasma pneumonia （MP） complicated with recurrent respiratory tract infection （RRTI） in children. Methods 160 children with MP complicated with RRTI in a hospital from May 2014 to June 2015 were selected as study group, 160 children with MP during the same period were selected as control group. Analyzed clinical factors of MP complicated with RRTI. Results Neutropenia, continued positive mycoplasma antibody, eosinophilia, age, immune index were single clinical factors of MP complicated with RRTI. Multivariate logistic regression analysis showed that age between 4 to 6 years old, continued positive antibody, reduced granulocyte, increased eosinophilic cell, reduced CD4/CDS, low level of lgA were independent risk factors （P〈0.05）, Conclusion There are many independent risk factors of mycoplasma pneumonia complicated with recurrent respiratory infection, which need to cause enough attention of clinical medical staff in order to reduce the probability of occurrence of the disease.
