Study hypothesis
To investigate the effect of withdrawal of inhaled seretide on airway inflammation and airflow limitation in Chronic Obstructive Pulmonary Disease (COPD) patients using non-invasive measurement methods and lung function tests.
Please note that this record was extensively updated on the 9th November 2007. Updates were performed to the ethics, inclusion criteria, interventions and secondary outcome measures, as some of this information was not provided in the original record. Where changes have been made, the update date (09/11/2007) has been mentioned. Also please note that previous to this update, the anticipated end date of this trial was 03/07/2006.
Ethics approval

Condition
Chronic Obstructive Pulmonary Disease (COPD)
Intervention
1. Seretide withdrawal group (withdrawal of Seretide dose for six weeks)
2. Continuation group
Added on 09/11/2007:
Patients will undergo spirometry, impulse oscillometry, body plethysmography, exhaled breath condensate, exhaled nitric oxide, induced sputum and questionaires at two occasions 2 weeks apart prior to randomisation and then at 2 weekly intervals for 6 weeks.
Intervention type
Drug
Phase
Not Specified
Drug names
Seretide
Primary outcome measure
Induced sputum inflammatory cell counts
Secondary outcome measures
Added on 09/11/2007:
1. Exhaled breath condensate pH
2. Exhaled breath condensate Leukotriene B4, 8-isoprostane and other metabolites
3. Exhaled breath condensate and serum metabolite profiling by mass spectrometry
4. Exhaled nitric oxide in parts per billion (at 50 mls/sec, Caw, Calvin and Diffusing Capacity)
5. Induced sputum messenger Ribonucleic Acid (RNA) and protein for inflammatory mediators (e.g., Interleukin-8 [IL-8], Interleukin-6 [IL-6])
6. Sputum and blood gene expression (e.g., glucocorticoid receptor)
7. FEV1, Maximal Expiratory Flow (MEF), FVC (measured by spirometry)
8. Total Lung Capacity (TLC), Residual Volume (RV), Functional Residual Capacity (FRC), Inspiratory Capacity (IC), specific airways conductance (sGaw), airway flow resistance (Raw) (measured by body plethysmography)
9. Resonant Frequency (RF), Respiratory resistance at 5 Hz (R5), reactance at 5 Hz (X5) (measured by impulse oscillometry)
