Conclusion and Implications
- The results show that the majority of Chinese patients with stable COPD had absolute BEC <300 cells/µL; the observed proportion and overall distribution of eosinophils in Chinese patients is similar to that of the non-Chinese patient population.
- According to GOLD recommendations3, these Chinese patients with absolute BEC <300 cells/µL might not require ICS containing therapy as initial pharmacological treatment.
- Limitations: These findings are based on blood eosinophil data of a relatively small sample captured at a single point in time; larger samples and longitudinal studies are needed to further investigate the distribution and stability of blood eosinophil status in this population.
