Lung disease is a rare complication of inflammatory bowel disease (IBD
). Herein is a series of seven IBD patients who developed new, persist
ent and unexplained symptoms of respiratory disease, particularly chro
nic productive cough. Using a CT scan of the chest, a diagnosis of bro
nchiectasis was made in five patients, while the diagnosis of chronic
bronchitis was made in two patients. Factors, other than IBD, that cou
ld account for pulmonary disease in these patients were absent. Severa
l important clinical patterns for IBD-associated large airway disease
mere uncovered and are reviewed in light of earlier case reports in th
e medical literature. A discussion regarding the possible pathogenesis
of IBD-associated airway disease follows.
