[Bronchopulmonary manifestations of gastroenterologic and hepatic diseases].
Topics of this review are the bronchopulmonary manifestations of gastroesophageal reflux disease, cirrhosis of the liver and chronic inflammatory bowel diseases. About 20% of patients with chronic obstructive airway disease show evidence of gastroesophageal reflux disease. Reflux bronchoconstriction seems to be of greater importance than microaspiration. First studies show the positive effects of acid inhibition by proton pump inhibitors on pulmonary symptoms. Hepatorenal syndrome is characterized by arterial hypoxemia with PaO2-values < 70 mm Hg. Different mediators (endotoxins, amines, polypeptides or allergens) are discussed. Furthermore, elevated levels of prostacycline, atrial natriuretic factor and platelet activating factor have been described. Recently published studies focused on the role of nitric oxide (NO). Patients with cirrhosis of the liver show a higher rate of a pathologically elevated airway resistance which might be induced by a reduced histamine clearance. Ascites leads to reversible restrictive airway disease. Bronchopulmonary manifestations in chronic inflammatory bowel diseases include obstructive and restrictive airway diseases, vascular or serosal changes and show low clinical evidence. In contrast, pathological changes of the common function tests were found in 30 to 50%. These findings may be induced by circulating immune complexes, vasculitis, increased permeability or a combined immune reaction of both, the bronchial and intestinal mucosa. Undesired effects of salicylates should be taken into account. This review shows that bronchopulmonary manifestations in diseases of the Gl-tract or the liver are more common than usually known and should be taken into clinical consideration.
