Abstract

|
Asthma and chronic obstructive pulmonary disease (COPD) are common respiratory diseases encountered in daily practice. Although each of these diseases is easily distinguishable from the other, patients sometimes have the features of both diseases, which has been termed asthma-COPD overlap syndrome (ACOS or ACO). Although a considerable amount of effort has been spent in defining ACO, there are currently no clear clinical criteria to diagnose ACO. Accordingly, the prevalence varies considerably depending on the criteria applied, and the clinical outcomes are inconsistent. Furthermore, the ideal treatment for ACO has not been fully investigated. Thus, continuous attempts to define ACO as a distinct disease have resulted in heterogeneous data, which can confuse clinicians more to diagnose and treat ACO. A return to the simplified concept of having two different diseases (COPD and asthma) in one patient may be more helpful to clinicians than aggressive attempts to define ACO as a distinct disease.
