The causes of chronic cough in China and its relations with geography, seasonality, age, and sex are largely uncertain.
A prospective, multicenter survey was conducted to evaluate patients with chronic cough across five regions in China by using a modified diagnostic algorithm. The effects of geography, seasonality, age, and sex on spectrum of chronic cough were also investigated.
The current study evaluated 704 adult patients, including 315 men (44.7%) and 389 women (55.3%). The causes of chronic cough were determined in 640 subjects (90.9%). Common causes included cough variant asthma (CVA) (32.6%), upper airway cough syndrome (UACS) (18.6%), eosinophilic bronchitis (EB) (17.2%), and atopic cough (AC) (13.2%). Collectively, these four causes accounted for 75.2% to 87.6% across five different regions without significant difference (P > .05), although there was variation on single causes. Gastroesophageal reflux-related cough was identified in 4.6% of causes. Seasonality, sex, and age were not associated with the spectrum of chronic cough (all P > .05).
CVA, UACS, EB, and AC were common causes of chronic cough in China. Geography, seasonality, age, and sex were not associated with the spectrum of chronic cough.
中国慢性咳嗽的病因及其与地理、季节、年龄和性别之间的关系在很大程度上尚不清楚。
采用改良诊断算法,对中国五个地区的慢性咳嗽患者进行前瞻性、多中心调查,评估患者情况。同时还研究了地理、季节、年龄和性别对慢性咳嗽谱的影响。
本研究共评估了 704 例成年患者,其中男性 315 例(44.7%),女性 389 例(55.3%)。640 例患者(90.9%)确定了慢性咳嗽的病因。常见病因包括咳嗽变异性哮喘(CVA)(32.6%)、上气道咳嗽综合征(UACS)(18.6%)、嗜酸粒细胞性支气管炎(EB)(17.2%)和变应性咳嗽(AC)(13.2%)。这四种病因在五个不同地区的总占比为 75.2%~87.6%,差异无统计学意义(P >.05),尽管各病因的占比存在差异。胃食管反流相关咳嗽占病因的 4.6%。季节、性别和年龄与慢性咳嗽谱无关(均 P >.05)。
CVA、UACS、EB 和 AC 是中国慢性咳嗽的常见病因。地理、季节、年龄和性别与慢性咳嗽谱无关。
