Eosinophil Inflammation and Hyperresponsiveness in the Airways as Phenotypes of COPD, and Usefulness of Inhaled Glucocorticosteroids

Conclusions: Airway eosinophilia and airway hyperresponsiveness are complicated with 25 – 50% of COPD that have no symptom and history for asthma. These phenotypes of COPD are closely related to symptom stability and reactivity to glucocortisosteroids. These phenotypes may play key roles for advancement of the management and therapy of this disease.
