Evaluation Inhaled Corticosteroids on Exhaled Nitric Oxide Gas Exchange
Evaluation of the Effects of Varying Doses of Inhaled Corticosteroids on Suppression of Total Exhaled, Bronchial, and Alveolar Nitric Oxide as Markers of Endogenous Inflammation in Patients With Moderate-to-severe COPD

To evaluate the role of inhaled corticosteroids to suppress nitric oxide gas exchange in stable patients with moderate-to-severe COPD who are current non-smokers and not on oral corticosteroids.

Stable, non-smoking COPD patients not on oral corticosteroids will be randomized in single blinded study to evaluate nitric oxide gas exchange at baseline, and subsequent effects of fluticasone 100mcg/salmeterol 50mcg bid, and fluticasone 250mcg/salmeterol 50mcg bid. Primary end points will include measurements of nitric oxide at varying expiratory flow rates to calculate bronchial, and small airway/alveolar nitric oxide. Secondary end points will evaluate lung function. Exhaled nitric oxide production presumably reflects endogenous inflammation. Normal healthy, non-smoking controls will be used for comparison, with exhaled nitric oxide measured before and after 3 weeks of low dose inhlaed corticosteroids.
