26 May 2025 • A new analysis of COPD patients shows that elevated blood eosinophil counts (BEC ≥ 300 cells/µL) are linked to a higher prevalence of extrapulmonary comorbidities (85.4% vs. 71.5%).

High BEC was associated with doubled odds of any non-pulmonary condition (OR = 2.03), including congestive heart failure (OR = 1.69) and renal dysfunction (OR = 1.95), but showed no significant link to pulmonary comorbidities.

The findings underscore the value of BEC as a marker for systemic risk in COPD management.
