Neutrophil Elastase Activity Is Associated with Exacerbations and Lung Function Decline in Bronchiectasis

Abstract
Rationale: Sputum neutrophil elastase and serum desmosine, which is a linked marker of endogenous elastin degradation, are possible biomarkers of disease severity and progression in bronchiectasis. This study aimed to determine the association of elastase activity and desmosine with exacerbations and lung function decline in bronchiectasis.
