Abstract

The cause of Crohn's disease is unknown, although alterations in intestinal permeability may play a primary role. Because we were interested in permeability changes that occur before the onset of intestinal inflammation, we took advantage of the known genetic predisposition to this disease and studied not only patients with Crohn's disease, but their clinically unaffected relatives as well. Intestinal permeability was assessed using the marker polyethylene glycol-400 ingested with a standard meal. We found that 17 normal volunteers absorbed 215 ± 29.6 mg (mean ± SE), whereas 11 patients with Crohn's disease absorbed 514 ± 94.7 mg and their 32 healthy relatives absorbed 566 ± 62.4 mg. The twofold increase in permeability in patients and their relatives (p < 0.005 compared with controls) indicates that the intestinal defect in the ability to exclude larger sized molecules is not secondary to clinically recognized intestinal inflammation, but is a primary defect that may be an etiologic factor in this disease.
