Abstract

Objectives: The effect of hypoxic relapse of chronic obstructive pulmonary disease (COPD) on lung adenosine triphosphate (ATP) concentration was studied measuring ATP in exhaled breath condensate (EBC). Subjects: Thirty COPD patients with severe exacerbation, thirteen healthy non-smokers and thirteen healthy smokers. Methods: ATP was detected using a luciferin-luciferase assay, dilution of airway droplets in EBC was assessed measuring sample conductivity. Results: ATP concentrations were similar in COPD patients, non-smoking and smoking healthy individuals (141 ± 44, 115 ± 21 and 90 ± 15 pM; p = 0.66). After treatment oxygenation of COPD patients improved (6.85 ± 1.29 kPa vs 8.20 ± 1.28 kPa, p
