Asthma–chronic obstructive pulmonary disease overlap syndrome – a brief review

Asthma and chronic obstructive pulmonary disease (COPD) are common disease observed worldwide. The etiologies of these conditions may be different, but their manifestations lead to inflammation and limited airflow. A small subject of population doesn’t meet the criteria of asthma or COPD. As a result, in more recent, years a new clinical entity has gained attraction that encompasses the criteria of both asthma and COPD called Asthma COPD overlap syndrome (ACOS). Thus far, no universal guidelines have been established, therefore, making it problematic for physician to develop a successful treatment strategy for their patients. This review provides a brief description of ACOS including risk factors and treatments. A Medline/PubMED search was performed to find articles with “ACOS” as a heading.
