支气管哮喘(简称哮喘)是全世界广泛流行的一种慢性呼吸道疾病。不同国家及地区间哮喘的患病率为9%~12%[1]。为期2年的调查研究显示,哮喘患者中由于症状急性加重而强化治疗者约占70%,其中36%的患者需住院治疗[2]。尽管《全球哮喘防治创议》(GINA)等多个哮喘防治指南在临床广泛应用,但哮喘的控制水平仍不容乐观[3]。哮喘控制测试(ACT评分)结果显示,虽然68%的哮喘患者认为自己的哮喘已经达到完全控制,但是在这些患者中,哮喘实际控制水平达到完全控制者仅占9%,34%的患者达到部分控制,而57%的患者哮喘控制情况为未控制[2]。研究结果表明,哮喘患者的
Bronchial asthma (asthma) is a chronic respiratory disease that is prevalent in the world. The prevalence of asthma in different countries and regions is 9% ~ 12% [1]. A two-year survey shows that about 70% of patients with asthma experience intensive treatment due to acute exacerbations, and 36% require hospitalization [2]. Although many guidelines for the prevention and treatment of asthma such as GINA are widely used clinically, the level of asthma control is still not optimistic [3]. Results from the Asthma Control Test (ACT Score) showed that while 68% of asthmatics considered their asthma to be in complete control, only 9% of patients had full control of asthma and 34% achieved partial control Control, while 57% of patients with asthma control was uncontrolled [2]. The findings show that patients with asthma
