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.

Condition Intervention
COPD Drug: fluticasone 100mcg/ salmeterol 50mcg Drug: fluticasone 250/salmeterol 50 Drug: salmeterol Drug: Salmeterol Drug: salmeterol and fluticasone propionate

Study Type: Observational
Study Design: Observational Model: Ecologic or Community
Time Perspective: Prospective
Official Title: 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

Enrollment: 39
Study Start Date: January 2006
Study Completion Date: October 2013
Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
long acting bronchodilator
salmeterol 50mcg bid by DPI, no fluticasone in patients with COPD/emphysema to evaluate effect on bronchodilation and exhaled nitric oxide
Drug: Salmeterol
salmeterol 50mcg bid X 3months
Other Name: serevent 50 mcg disk
bronchodilator/ inhaled corticosteroid
fluticasone 250mcg/salmeterol 50 mcg bid X 3momths to evaluate effect on lung function and exhaled nitric oxide
Drug: fluticasone 250/salmeterol 50
inhaled fluticasone 250/salmeterol 50 X 3 months to evaluate effect on lung function and exhaled nitric oxide
Other Name: Advair 250/50
Drug: salmeterol and fluticasone propionate
salmeterol 50mcg/fluticasone 250mcg by DPI bid
Other Name: Advair 250/50
Fluticasone 100mcg/salmeterol 50mcg
Drug: fluticasone 100mcg/ salmeterol 50mcg
inhaled fluticasone 100mcg/salmeterol 50mcg bid X 3 months
Other Name: Advair 100/50
Drug: salmeterol
salmeterol 50 mcg by dry powder inhaler disk bid to evaluated effect on lung function and exhaled nitric oxide
Other Name: Serevent 50mcg

Detailed Description:
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.
