This is a condition in which the total body iron is increased to 20-60 g (normal 4 g). The excess iron is deposited in and damages several organs.
• liver ^ cirrhosis (one-third develop a hepatoma)
• skin ^ bronze or leaden grey colour
• heart ^ restrictive cardiomyopathy
• pituitary ^ hypogonadism: impotence etc.
• joints ^ arthralgia (esp. hands); chondrocalcinosis
It may be primary (hereditary—autosomal recessive) or secondary (e.g. chronic haemolysis, T dietary iron, multiple transfusions).
(maybe) extreme lethargy, polyuria & poly-dipsia, arthralgia, loss of libido (look for) hepatomegaly, very tanned skin, cardiac arrhythmias increased serum ferritin > 1000 •g/L or MRI—T iron deposition in liver liver biopsy (if LFT enzymes abnormal) ? nucleic acid amplification test
Screen first degree relatives (s. ferritin & iron binding capacity)
weekly venesection 500 mL (250 mg iron) until serum iron levels normal (may take at least 2 years) then every 3-4 months to keep s. ferritin (< 100 •g/L) and iron normal. Life expectancy is normal if treated before cirrhosis or diabetes develops. Normal diet
