Collaborator:
AstraZeneca
Information provided by:
Imperial College London
  Purpose
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
