The incidence of amyloidosis complicating inflammatory bowel disease. A prospective survey of 177 patients.
Three cases of secondary amyloidosis are reported, two in patients who had unequivocal Crohn's disease and one in whom the clinical course was that of Crohn's disease, but with histologic findings that were more suggestive of ulcerative colitis. All had evidence of renal failure. A prospective study of 177 patients with inflammatory bowel disease of greater than five years' duration was carried out in an attempt to establish the incidence of secondary amyloidosis, using rectal biopsy and simple renal function tests. No new cases were found. Neither was there evidence of renal failure due to other conditions. In the absence of renal dysfunction, a search for secondary amyloidosis probably is not justified.
