Autoimmune enteropathy in infants. Pathological study of the disease in two familial cases.
In two brothers with autoimmune enteropathy there was total villous atrophy in the small intestine and marked lymphoid cell infiltration in the lamina propria of the entire digestive tract, discovered at autopsy in one of these patients. In addition, the pancreas showed diffuse interstitial infiltration by lymphocytes. The liver was enlarged, with extensive haematopoiesis and cholestasis. Similar lesions in the digestive tract were noticed in the second boy, but on immunosuppressive therapy his diarrhoea gradually disappeared. When he was 16 months of age, percutaneous biopsies showed moderately aggressive chronic hepatitis and a focal interstitial lymphoid infiltrate in the kidney. After 3 years of immunosuppressive therapy (prednisone, cyclosporin), the child ate well and total parenteral nutrition was discontinued. The intestinal lesions had regressed but fibrotic lesions of the liver persisted.
