title: Hemochromatosis: diagnosis and treatment.
abstract: What then are the lessons to be learned about prevention and treatment of hemochromatosis? Early diagnosis is essential. The best indicator would be testing of serum iron and total saturation followed by a serum ferritin if elevated. Once these indices are abnormally high, MRI and or a liver biopsy should confirm the stage of the iron over-loaded state. If indeed the patient is not iron-overloaded (normal liver biopsy in the face of high saturation and ferritin level) phlebotomies should be performed until these indices are normal and then maintained at a normal level. This should entail four to six phlebotomies a year. Family members should also be screened and managed in a like manner. HLA typing may be a partially helpful screening device. The abnormal gene is closely linked on chromosome 6 with HLA histocompatibility loci. Now, by means of HLA typing, we can identify heterozygote carriers and homozygous (abnormal) among first degree relatives of patients with hemochromatosis. Unfortunately, HLA typing can only be used within a given family and cannot be used to screen the general population. It is estimated that 70% of hemochromatoics have the antigen HLA-A3; however, so does 28% of the (well) general population. Patients with unexplained cirrhosis, arthritis, liver disease, diabetes, impotency, cardiomyopathy and neurological symptoms should be screened in a like manner. Routine health practice profile chemistries must include a serum iron and iron saturation, and if high followed by a serum ferritin. Once diagnosed, therapy must be maintained with phlebotomy for the life time of the patient.(ABSTRACT TRUNCATED AT 250 WORDS)
