喉源性咳嗽与肺炎支原体感染的关系研究

The relationship research beatween throat source cough and mycoplasma pneumoniae infection

目的探讨喉源性咳嗽与肺炎支原体感染发病的关系。方法收集2013年7月-2014年7月广西中医药大学第一附属医院耳鼻喉科门诊就诊以咳嗽为主要症状且胸部X线片正常的喉源性咳嗽与喉痹患者273例，采用血清被动明胶颗粒凝集法检测MP—IgM，检测喉源性咳嗽组与喉痹组的血清肺炎支原体抗体，统计分析喉源性咳嗽与肺炎支原体抗体之间的相关性。结果喉源性咳嗽组肺炎支原体抗体阳性率为50．4％，喉痹组肺炎支原体抗体阳性率为7．3％，两者有差异（P〈0.05）。结论肺炎支原体作为变应原使机体致敏，喉源性咳嗽与肺炎支原体感染有一定的相关。

Objective To evaluate the relationship beatween throat source cough and mycoplasma pneumoniae infection. Methods 273 patients whose main symptom was on cough but chest X ray film is normal ,being diagnosed with throat source cough or throat bi , were collected in the otolaryngology clinic of the first affiliated hospital of guangxi medical university in July 2013 to July2014. The method of polystyrene latex agglutination reaction（PLA） is used to detect mycoplasma pneumoniae （MP） IgM, with which to detect antibody of MP in the throat source cough and throat bi group, to make statistic analysis the correlation between throat source cough and MP infection. Results The incidence of antibody of MP in the throat source cough and throat bi group is 50. 4% and 7. 3%, respectively. The difference was statistically significant between the two groups（P〈0.05）. ConcLusion MP make the body sensitization as allergens,and throat source cough associated with MP infection has certain.
