COPD & EOS PHENOTYPE

COPD is a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea, cough, sputum production, and/or exacerbations) due to abnormalities of the airways and/or alveoli that cause persistent, progressive airflow obstruction.1

COPD prevalence

In the United States, COPD affects ~14.2 million people (reported in 2021).2

Elevated eosinophils can play a key role in COPD

The GOLD Report acknowledges that higher BEC in patients with COPD is associated with increased lung eosinophil counts and the presence of higher levels of markers of type 2 inflammation in the airways.1 Type 2 inflammation characterized by blood eosinophils in patients with COPD is associated with increased risk, frequency, and severity of exacerbations.1,3,4

Patients with an EOS phenotype are at greater risk of COPD exacerbations and related hospital visits*

Up to 76% (25-76%) greater risk of COPD exacerbations Up to 76% (25-76%) greater risk of COPD exacerbations
Up to 68% (18-68%) greater risk of hospital visits due to COPD exacerbations Up to 68% (18-68%) greater risk of hospital visits due to COPD exacerbations

*Hospitalizations or ED visits.

†Across BEC thresholds (cells/µL): ≥300 vs <300, RR: 1.25; ≥400 vs <400, RR: 1.48; ≥500 vs <500, RR: 1.76.4 Results are descriptive.

‡Across BEC thresholds (cells/µL): ≥300 vs <300, RR: 1.18; ≥400 vs <400, RR: 1.44; ≥500 vs <500, RR: 1.68.4 Results are descriptive.

Retrospective cohort study in a managed care setting (Kaiser Permanente Southern California Research Data Warehouse, 2009-2012) that examined the relationship between baseline BEC and COPD exacerbations in the 1-year follow-up of 7245 patients aged ≥40 years diagnosed with COPD. COPD exacerbations were defined as hospitalizations or ED visits with a primary diagnosis of COPD, or outpatient visits with systemic corticosteroid dispensing within 14 days of an exacerbation.4
