Site predilection of airway inflammation by emphysema type
Abstract:
To elucidate interrelations of airway inflammation and emphysema, bronchi from subjects with severe panlobular and centrilobular disease and normal lungs were compared. This disclosed an intense infiltration with chronic inflammatory cells, mucous gland hypertrophy, and thickening of bronchi, primarily in association with emphysema having a panlobular configuration. These changes complement a generalized thickening and inflammation of nonrespiratory bronchioles previously observed in these cases. We conclude that the panlobular pattern may be a close function of inflammatory thickening of the conductive airways to respective lungs and lung parts, but centrilobular emphysema is not reliant on these changes. The precursory defect for the centrilobular lesion instead has been shown to be a more peripherally oriented respiratory bronchiolitis around the centers of lobules.
