COPD exacerbations are heterogeneous in terms of airway inflammation and aetiology. About 60% of COPD patients have blood eosinophil counts of ≥2%, which appears to be associated with an increased risk of exacerbations [1–3]. However, the association between blood eosinophil counts at stable disease and COPD exacerbations in the subsequent year is incompletely understood.Blood eosinophil count may serve as a biomarker of exacerbation risk in subgroups of patients with COPD http://ow.ly/6tm530cEAeO ER -
