Chronic cough is among the most common symptoms prompting medical care. Cough-variant asthma (CVA) is an asthma subset where cough is the primary symptom, without wheezing, chest tightness, or dyspnea. It is an important cause of chronic cough, estimated to account for 25% to 42% of cases, but likely underdiagnosed due to delayed recognition and pitfalls of diagnostic testing. Early recognition and treatment can reduce morbidity and delay its progression to more typical asthma. This review details the clinical characteristics, diagnosis, pathophysiology, and treatment of CVA and contrasts it with classic asthma and other causes of chronic cough.
慢性咳嗽是促使就医的最常见症状之一。咳嗽变异性哮喘(CVA)是哮喘的一个亚型,其主要症状为咳嗽,无喘息、胸闷或呼吸困难。它是慢性咳嗽的一个重要原因,估计占病例的25%至42%,但由于诊断延迟和诊断测试的缺陷,可能未得到充分诊断。早期识别和治疗可降低发病率,并延缓其发展为更典型的哮喘。本文综述详细介绍了咳嗽变异性哮喘的临床特征、诊断、病理生理学和治疗,并将其与经典哮喘和其他慢性咳嗽原因进行了对比。
