[Idiopathic hemochromatosis--diagnosis and therapy]
Insights
Idiopathic haemochromatosis causes dangerous iron overload, leading to organ damage and serious health issues. Early diagnosis through iron level tests and family screening, followed by regular bloodletting, is key for managing this genetic disorder.
Area of Science:
- Hematology
- Genetics
- Endocrinology
Context:
- Idiopathic haemochromatosis is a genetic disorder characterized by excessive iron accumulation.
- Iron overload can result in severe organ damage, including cardiac insufficiency and liver cirrhosis.
- Symptoms like melanoderma, diabetes mellitus, and arthropathy often manifest in various combinations.
Purpose:
- To outline the diagnostic criteria for idiopathic haemochromatosis.
- To emphasize key laboratory tests for diagnosis and family screening.
- To describe the recommended therapeutic strategies for managing iron overload.
Summary:
- Diagnosis involves confirming iron storage, identifying multiple organ affections, and recognizing familial clustering.
- Key diagnostic tests include serum iron, transferrin saturation, serum ferritin, desferrioxamine test, ferrokinetics, and liver biopsy iron quantification.
- HLA typing is valuable for family risk assessment, particularly for siblings.
Impact:
- The primary treatment involves phlebotomy (bloodletting) to induce a manageable iron deficiency anemia.
- Maintenance therapy requires periodic bloodletting.
- Specific treatments are necessary for associated endocrine failures and cardiac disturbances.
Abstract:
The excessive storage of iron in idiopathic haemochromatosis leads to severe organic lesion up to life-threatening conditions (cardiac insufficiency, portal decompensation). The symptoms melanodermia , diabetes mellitus and other endocrine failures, liver cirrhosis, cardiac insufficiency and arthropathy appear together or in various combinations. The diagnosis is ascertained by the proof of iron storage, the multiple organic affection and by familial accumulation of the various laboratory diagnostic possibilities are particularly to be emphasized the serum iron value together with the percetal transferrin saturation (as search test), serum ferritin, the desferrioxamine test, simple ferrokinetic investigations and the quantitative determination of iron in the liver in the bioptate . For family examinations, apart from the search test, a HLA typisation is reasonable, in order to estimate the risk of the disease (particularly of brothers and sisters). The therapy of choice are blood- lettings (0.5 l once to twice a week) up to obtaining a permanent easy iron deficiency anaemia. The maintenance therapy should be performed with monthly to quarterly blood- lettings . Only in cases exception a desferal treatment is indicated. Endocrine failures and cardiac disturbances need a particular therapy.
