Trial summary

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… Read more about this study

About this study

Official title: Non-Invasive Markers for Chronic Obstructive Pulmonary Disease (COPD)

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).

Being tested
Spirometry, Exhaled Nitric Oxide and Carbon Monoxide, Exhaled Breath Condensate, Induced Sputum, CT Scan
