Blood and sputum eosinophilia are key biomarkers in chronic obstructive pulmonary disease (COPD), predicting exacerbations and guiding inhaled glucocorticosteroid therapy for personalized treatment.
Area of Science:
- Pulmonology
- Biomarkers
- Personalized Medicine
Background:
- Chronic obstructive pulmonary disease (COPD) is a complex, heterogeneous respiratory condition.
- Understanding COPD phenotypes and endotypes is crucial for effective patient management.
- Biomarkers are essential for implementing personalized therapeutic strategies in COPD.
Purpose of the Study:
- To highlight the significance of eosinophilia as a biomarker in COPD.
- To discuss the role of eosinophilic inflammation in COPD prognosis and clinical parameters.
- To explore targeted therapies for eosinophilic COPD.
Main Methods:
- Literature review on eosinophilia in COPD.
- Analysis of studies on biomarkers for COPD phenotyping.
- Examination of research on inhaled glucocorticosteroids and eosinophilic inflammation.
Main Results:
- Eosinophilia in blood and/or sputum is a critical COPD biomarker.
- Eosinophilia predicts frequent COPD exacerbations.
- Eosinophilia indicates effectiveness of inhaled glucocorticosteroids in COPD patients.
Conclusions:
- Eosinophilic inflammation impacts COPD prognosis and clinical outcomes.
- Targeted therapies are being developed for eosinophilic COPD.
- Biomarker-guided approaches are vital for personalized COPD treatment.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
