不明原因慢性咳嗽的诊断与治疗

目的:研究慢性咳嗽的病因分布及针对病因实施治疗的有效率.方法:91例慢性咳嗽患者应用慢性咳嗽解剖学诊断程序 诱导痰细胞学分类进行病因诊断,并针对病因实施特异性治疗.结果:病因诊断率为90%(82/91),病因未明10%(9/91),其中咳嗽变异性哮喘占31%(29/91),病毒感染后咳嗽占18%(17/91),嗜酸细胞性支气管炎占14%(13/91),鼻后滴漏综合症占8%(7/91),胃食管反流性咳嗽占5%(4/91).82例明确诊断患者实施针对性治疗,治疗有效率93.3%(77/82).结论:慢性咳嗽解剖学诊断程序 诱导痰细胞学分类能使大部分慢性咳嗽患者病因明确,针对性治疗有效.

Diagnosis and treatment of chronic cough with unknown causes

Objective To explore the spectrum and frequency of causes for chronic cough. Methods The efficacy of therapy to the diagnosis was evaluated. Results Definite diagnosis was made in 82(90%), of the 91 patients with chronic cough.The most common causes included cough variant asthma(29/91,31%), cough after virus infection (17/91,18%),eosinophilic bronchitis(13/91,14%), postnasal drip syndrome(7/91,8%)and gastroesophageal refux(4/91,5%).After active treatment based on the diagnosis cure rate of 93.3% was achieved. Conclusion A positive response to the soecific therapy is essential to a definite diagnosis.
