Sickle cell disease and hemochromatosis

A 50 year-old patient with sickle cell anemia was seen who had received only two units of blood during his lifetime. He had marked iron overloading, cirrhosis of the liver, arthralgia, and mild glucose intolerance. We believe the iron overloading was associated with hereditary hemochromatosis rather than sickle cell anemia because he had HLA-A3 and B7 antigens, and hepatic iron deposits were primarily in parenchymal cells rather than Kupfer cells. The coexistence of either homozygous or heterozygous hemochromatosis should be suspected in sickle cell patients with organ damage from iron overloading.
