[Clinical experience with early hemochromatosis].

During the period 1986-93 22 patients were diagnosed as having primary hemochromatosis. Only 11 of them had elevated aminotransferases. Transferrin saturation was higher > 63% in 17 (77%) and serum-ferritin was higher in all the patients. (257 mumol/l to 6,500 mumol/l). A percutaneous liver biopsy was performed in 20 patients, all of whom showed a characteristic grading from 2 + to 4+ using Perls' stain. Two males had cirrhosis with simultaneous hepatocellular carcinoma, and another two had cirrhosis. One patient had diabetes mellitus type I. We conclude that fasting serum-iron and transferrin should be determined in all subjects over 40 years of age and in patients with chronic elevation of liver enzymes. If transferrin saturation is higher than 50% in females and 60% in males, serum ferritin should be determined. A percutaneous liver biopsy should be performed if both values are higher than normal. Screening of siblings is important because of the autosomal recessive pattern of inheritance.
