title: Hereditary hemochromatosis: diagnosis and treatment in primary care.
abstract: Hereditary hemochromatosis (HHC) is one of the most common inherited disorders in the Caucasian population. Diagnosis usually made after an elevation in ferritin and serum transferrin saturation is noted, often accompanied by asymptomatic hepatomegaly. Diagnosis is confirmed by genetic testing or liver biopsy. Damage to organs is due to excessive intestinal iron, which is transported to and then deposited in the liver parenchyma, and the heart, skin, and endocrine organs, causing skin pigmentation, development of cirrhosis and hepatic carcinoma, diabetes and endocrine failure, and heart failure. Bony changes can be manifested by arthritis, often in non-weight-bearing joints. The treatment of HHC is phlebotomy, which depletes iron stores. When diagnosis is made before organ damage occurs, treatment can prevent manifestations of the disease. Skin pigmentation and some cardiac damage may reverse on depletion of iron stores, but liver and endocrine damage is rarely reversible. Arthropathy is also not reversible, and often continues to progress even with effective treatment. When hemochromatosis is diagnosed, all first degree relatives of the patient should undergo genetic testing. With early detection and treatment this can be a manageable chronic disease. If undetected, it is potentially fatal.
