Abstract/OtherAbstract:
Hereditary hemochromatosis is a prevalent inherited disorder with an estimated frequency of homozygosity of 0.2 to 0.45% in Caucasians. The disease is characterized by progressive iron overload until a massive accumulation of body iron occurs. Undetected, the disorder eventually can produce either cirrhosis, diabetes mellitus, cardiac disease, arthritis, or hepatocellular carcinoma or a combination of these manifestations. Early diagnosis and treatment prevents organ damage and normalizes life expectancy. Screening studies to detect hemochromatosis are most effectively accomplished by measurement of the serum iron and total iron binding capacity. Treatment is most effectively performed by frequent phlebotomy until body stores are empty and then 3 to 4 times yearly for life. The basic defect of hemochromatosis appears to increase iron absorption, decrease iron excretion, and produce preferential deposit of iron in hepatic parenchymal cells rather than Kupffer cells. The genetic abnormality of hemochromatosis is located on chromosome 6 in close association with the gene for HLA antigens. Recent speculation postulates that tumor necrosis factor may be involved in the etiology of this disease because of its location on chromosome 6 and its effect upon iron transport.
