Summary

The measurement of markers in the expired breath condensate has proven to be a useful method for assessing and monitoring airway inflammation. The aim of this study is to determine the amounts of pH in the expired breath condensate of patients with bronchiectasis, and the relationship between pH and the severity of bronchiectasis.

Detailed description

The aim of this study is to determine the amounts of pH in the expired breath condensate of patients with bronchiectasis, and the relationship between pH and the severity of bronchiectasis. Further clarify the link between EBC pH and the risk of future acute exacerbations, mortality and lung function decline through a one-year follow-up. Hoping to explore new validated biomarkers of the disease severity and progression in bronchiectasis. During the observation, EBC pH and other valid indicators will be measured when patients were enrolled.
