Assessment of Airway Remodeling Using Endobronchial Ultrasound in Asthma-COPD Overlap.

The process of structural changes in the airways assessed by EBUS is more advanced in individuals with ACO compared to patients with COPD, and less pronounced compared to patients with severe asthma. It seems that EBUS may provide useful information about differences in airway remodeling between ACO, COPD and severe asthma.
