    Blood eosinophilia is recognized as a biomarker of type 2 inflammation in both asthma and chronic obstructive airway diseases (COPD).

  • 2

    A clinical case demonstrated that a patient initially diagnosed with severe COPD was later reclassified as having severe eosinophilic asthma after reassessment.

  • 3

    The patient showed significant clinical improvement after treatment with mepolizumab, despite no notable change in lung function.

  • 4

    Eosinophilic inflammation is typically associated with asthma, while COPD is usually characterized by neutrophilic inflammation.

  • 5

    Blood eosinophilia may serve as a clinically actionable trait for guiding diagnosis and personalized therapy in chronic airway diseases.
