title: [Renal amyloidosis in a case of Crohn disease with colonic and rectal involvement].
abstract: A clinical case characterized by renal amyloidosis, Crohn's disease of the colon and rectum, multiple chronic anal fistulae and ankylosing spondylitis is reported. This association has been infrequently recognized. In this patient Crohn's disease became manifest at 20 years of age and underwent a chronic and relapsing course. Proteinuria and renal amyloidosis were detected after eight years of evolution. Panproctocolectomy was performed. The patient progressed satisfactorily and six months later he remains asymptomatic, free from medication and with normal creatinine clearance. The authors recommend early surgical treatment on the diseased intestinal segment once the association has been diagnosed and before serious impairment of renal function has occurred.
