80例慢性咳嗽的病因分析

Etiological Analysis of 80 Cases of Chronic Cough

目的探讨慢性咳嗽的病因分布特点。方法对80例慢性咳嗽患者,按照慢性咳嗽的解剖学诊断程序,根据病史、体格检查、实验室检查及特异性治疗反应,判定病因。结果 80例患者慢性咳嗽的病因为咳嗽变异性哮喘(CVA)20例(25.0%),鼻后滴漏综合征(PNDS)14例(17.5%),胃食管反流性疾病(GERC)11例(13.7%),嗜酸粒细胞支气管炎(EB)9例(11.2%),ACEI诱发的咳嗽8例(10.0%),其他病因18例(22.5%)。结论 CVA、PNDS和GERC是慢性咳嗽的常见病因。

Objective To investigate the distribution of causes of chronic cough.Methods An anatomical diagnostic protocol was used and medical history taking,physical examination,laboratory tests and specific treatment response evaluation were performed to determine the causes of chronic cough in 80 patients.Results Among the 80 patients with chronic cough,cough variant asthma（CVA） was diagnosed as the cause of the cough in 20（25.0%）,postnasal drip syndrome（PNDS） in 14（17.5%）,gastroesophageal reflux disease（GERD） in 11（13.7%）,eosinophilic bronchitis（EB） in 9（11.2%）,ACEI in 8（10.0%）,and other causes in 18（22.5%）.Conclusion Chronic cough is induced mostly by CVA,PNDS and GERD.
