Asthma and chronic obstructive pulmonary disease (COPD) are markedly different airway diseases, but sometimes they overlap, with some asthmatic patients showing some features of COPD (fixed airway obstruction, mixed neutrophilic/eosinophilic airway inflammation, and relatively poor response to corticosteroids) and some patients with COPD having features of asthma (atopy, history of asthma, greater airway reversibility, increased blood and sputum eosinophil counts, and a clinical response to corticosteroids).
