不同病因慢性咳嗽的咳嗽程度比较

目的探讨不同病因慢性咳嗽患者咳嗽程度的异同及可能的影响因素。方法按慢性咳嗽病因诊断程序进行病因诊断，收集单一病因慢性咳嗽患者150例，通过咳嗽积分评价，比较不同病因患者日间及夜间咳嗽程度的差异及其与年龄、性别、病程的关系。结果纳入患者包括鼻后滴流综合征24例，咳嗽变异型哮喘26例、胃食管反流性咳嗽20例，嗜酸细胞性支气管炎31例，变应性咳嗽30例及感染后咳嗽19例。各组间的日间咳嗽积分比较差异无统计学意义（P〉0．05）。咳嗽变异型哮喘组的夜间秋分明显高于鼻后滴流综合征、胃食管反流性咳嗽、嗜酸粒细胞性支气管炎、变应性咳嗽及感染后咳嗽组（均P〈0．01）。分别对日间咳嗽积分和夜间咳嗽积分进行有序分类logistic回归分析，显示年龄与日间咳嗽积分有关（P〈0．05），性别与夜间咳嗽积分有关（P〈0．01）。结论不同病凶慢性咳嗽的日间咳嗽程度类似，但咳嗽变异型哮喘夜间咳嗽程度显著高于其他病因的咳嗽。

Cough score in patients with different etiology of chronic cough

Objective To investigate the severity of cough in patients with different etiology of chronic cough and its related factors. Methods One hundred and fifty patients with chronic cough were recruited. The diagnosis of the patients was as follows: 24 cases with post nasal drip syndrome (PNDs), 26 cough variant asthma (CVA), 20 gastroesophageal reflux-induced cough (GERC), 31 eosinophilic bronchitis (EB), 30 atopic cough (AC) and 19 cough post infection (CPI). The severity of cough at daytime and night-time were scored by the doctor and the patient at the first visit. The correlation between cough score and age, gender and course duration of patients was analyzed. Results There was no significantly difference of cough score at daytime among different groups. Cough score at night in CVA group was significantly higher than that of other five groups (all P <0.01). Regression analysis showed that cough score at daytime was significantly correlated with age of patients (P < 0.05), while cough score at night was correlated significantly with gender (P < 0.01). Conclusion Cough severity at daytime in different etiology of chronic cough is similar, while that at night in patient with CVA is higher than that with other etiology.
