Idiopathic hemochromatosis: serum ferritin concentrations during therapy by phlebotomy.

We report the case of a 54-year-old man who presented with symptoms of idiopathic hemochromatosis, an inherited disorder involving regulation of iron absorption. These symptoms usually do not appear until total body iron content reaches 15 g, about threefold normal. Therapy involves mobilization and removal of excess stored iron through weekly or twice-weekly phlebotomies of 500 mL, until the hemoglobin concentration becomes less than 110 g/L and remains there for several weeks, or until serum ferritin concentrations indicate that almost all the stored iron has been removed (ferritin less than 12 micrograms/L). Here, concentrations of ferritin in serum were used as an index to iron overload and removal of stored iron. We report changes in hemoglobin, serum ferritin, iron, and total iron-binding capacity during the course of removing by phlebotomy more than 20 g of iron from a patient with idiopathic hemochromatosis.
