Management of hereditary hemochromatosis

Hereditary hemochromatosis is a common disorder of iron metabolism with a prevalence as high as 8 per 1000. Affected individuals absorb excessive amounts of dietary iron and over time, tissue iron deposition results in skin discoloration, arthropathy, hepatic cirrhosis, heart failure, diabetes mellitus and impotence. Early diagnosis and institution of phlebotomy treatments will prevent these manifestations and normalize life expectancy. Once organ damage is established many of the manifestations are irreversible. Since the early manifestations of the disease are subtle, a case can be made for routine screening. This conclusion is supported by cost-effectiveness analysis based on available data. A reasonable screening strategy would start with a serum transferrin saturation. A value > or = 55% should trigger a repeat transferrin saturation in a fasting state and a serum ferritin level. If both these tests are abnormal, a liver biopsy with quantitative iron determination is the currently accepted confirmatory test.
