Last verified: September 2005
History: No changes posted
The primary aim of this study is to exploit a difference between COPD patients, chronic smokers without COPD and healthy non-smoking subjects. This will help to assess the utility of inflammatory and oxidative markers in exhaled air and sputum and to compare them with the lung function, clinical parameters and computerised tomography (CT).

Condition Intervention
Healthy Non-Smokers
Current Smokers
COPD Patients
Procedure: Spirometry
Procedure: Exhaled Nitric Oxide and Carbon Monoxide
Procedure: Exhaled Breath Condensate
Procedure: Induced Sputum
Procedure: CT Scan
Procedure: Blood test
Procedure: St Georges Questionnaire
Procedure: Bodypletysmography

Study Type: Observational
Study Design: Observational Model: Defined Population
Time Perspective: Longitudinal
Time Perspective: Prospective
Official Title: Non-Invasive Markers for COPD
