To comprehensively evaluate the etiology of chronic cough and the value of clinical feature in school age children in Suzhou, China.
School-age (6-14 years) children newly referred with chronic cough (>4 weeks) were prospectively evaluated by utilizing a diagnostic algorithm in this study. Clinical features of different etiologies of chronic cough were also investigated.
In total, 118 patients were enrolled in the study. The cough duration ranged from 1 to 76 months. Upper airway cough syndrome (UACS) was found in 77 (65.3%) patients with chronic cough, cough-variant asthma (CVA) in 57 (48.3%) patients, protracted bronchitis (PB) in 15 (12.7%) patients, gastroesophageal reflux disease (GERD) in 7 (5.9%) patients, tic disorders (TD) in 3 (2.5%) patients and eosinophilic bronchitis (EB) in 2 (1.7%) patients. A single etiology was present in 75 patients and multiple etiologies were present in 43 patients. The three most common single etiologies were UACS (31.4%), CVA (14.4%), and PB (10.2%), followed by GERD (5.9%), and EB (1.7%). The most common multiple etiology was CVA + UACS (31.4%), followed by CVA + PB (2.5%), and TD + UACS (2.5%).
The common etiologies of chronic cough in school-age children were UACS, CVA, and PB, while EB and GERD were rare.
全面评估中国苏州学龄儿童慢性咳嗽的病因及临床特征的价值。
本研究采用诊断算法对新转诊的学龄期（6 - 14岁）慢性咳嗽（>4周）儿童进行前瞻性评估。还调查了慢性咳嗽不同病因的临床特征。
本研究共纳入118例患者。咳嗽持续时间为1至76个月。77例（65.3%）慢性咳嗽患者被诊断为上气道咳嗽综合征（UACS），57例（48.3%）为咳嗽变异性哮喘（CVA），15例（12.7%）为迁延性支气管炎（PB），7例（5.9%）为胃食管反流病（GERD），3例（2.5%）为抽动障碍（TD），2例（1.7%）为嗜酸性粒细胞性支气管炎（EB）。75例患者为单一病因，43例患者为多种病因。三种最常见的单一病因是UACS（31.4%）、CVA（14.4%）和PB（10.2%），其次是GERD（5.9%）和EB（1.7%）。最常见的多种病因是CVA + UACS（31.4%），其次是CVA + PB（2.5%）和TD + UACS（2.5%）。
学龄儿童慢性咳嗽的常见病因是UACS、CVA和PB，而EB和GERD较为罕见。
