Smoking is a risk factor for developing chronic obstructive pulmonary disease (COPD), but there are no good indicators for early identification of subjects who will develop symptomatic COPD. The aim of this study was to investigate inflammatory mechanisms related to changes in lung function and emphysematous changes on high resolution computed tomography (HRCT) in ‘healthy’ smokers. Subjects were...
Cigarette smoking is the dominant risk factor for chronic obstructive pulmonary disease (COPD). However, only 10–15% of smokers develop the disease and early changes within the airways are poorly defined. We aimed to compare cell profiles in induced sputum (IS) from asymptomatic smokers to that from healthy subjects, and to ascertain whether or not inflammatory cells in IS are related to lung function...
