[Crohn's disease and amyloidosis. An association to be considered].

Two instances of Crohn's disease and amyloidosis are presented. The time elapsed between the diagnosis of Crohn's disease and that of amyloidosis was 2 and 8 years respectively. The first case had hepatosplenomegaly and moderate proteinuria; the other one, severe proteinuria in the nephrotic syndrome range. One patient had ileocolic disease and the other disease limited to the terminal ileum. In both cases renal functional was normal. The diagnosis was made by liver biopsy in one patient and by repeated renal biopsy in the one with nephrotic syndrome. Ileocolic resection was undertaken in one patient without complications. Screening for amyloidosis is important in patients with Crohn's disease.
