A strict low iron diet is usually not necessary. Non-heme iron is not as easily absorbed in the human system and is found in plant-based foods like grains, beans, vegetables, fruits, nuts, and seeds. 21 Medication: For those unable to tolerate routine blood draws, there are verkoudheid chelating agents available for use. 22 The drug deferoxamine binds with iron in the bloodstream and enhances its elimination in urine and faeces. Typical treatment for chronic iron overload requires subcutaneous injection over a period of 812 hours daily. Citation needed Two newer iron chelating drugs that are licensed for use in patients receiving regular blood transfusions to treat thalassaemia (and, thus, who develop iron overload as a result) are deferasirox and deferiprone. 23 24 Prognosis edit In general, provided there has been no liver damage, patients should expect a normal life expectancy if adequately treated by venesection. If the serum ferritin is greater than 1000 ug/L at diagnosis there is a risk of liver damage and cirrhosis which may eventually shorten their life. 25 The presence of cirrhosis increases the risk of hepatocellular carcinoma.

Once the serum ferritin and transferrin saturation are within the normal range, treatments may be scheduled every two to three months depending upon the rate of reabsorption of iron. A phlebotomy session typically draws between 450 and 500 mL of blood. 20 diet low in iron is generally recommended, but has little effect compared to venesection. The human diet contains iron in two forms - heme iron and non-heme iron. Heme iron is the most easily absorbed form of iron. People with iron overload may be advised to avoid food that are high in heme iron. Highest in heme iron is red meat such as beef, venison, lamb, buffalo, and fish such as bluefin tuna.

Citation needed dna/screening: the standard of practice in diagnosis of haemochromatosis pillen places emphasis on genetic testing. 18 Positive hfe analysis confirms the clinical diagnosis of haemochromatosis in asymptomatic individuals with blood tests showing increased iron stores, or for predictive testing of individuals with a family history of haemochromatosis. The alleles evaluated by hfe gene analysis are evident in 80 of patients with haemochromatosis; a negative report for hfe gene does not rule out haemochromatosis. First degree relatives of those with primary haemochromatosis should be screened to determine if they are a carrier or if they could develop the disease. This can allow preventive measures to be taken.
Screening the general population is not recommended. 19 liver biopsy is the removal of small sample in order to be studied and can determine the cause of inflammation or cirrhosis. In someone with negative hfe gene testing, elevated iron status for no other obvious reason, and family history of liver disease, additional evaluation of liver iron concentration is indicated. In this case, diagnosis of haemochromatosis is based on biochemical analysis and histologic examination of a liver sessment ontsmetten of the hepatic iron index (HII) is considered the "gold standard" for diagnosis of haemochromatosis. Magnetic resonance imaging (MRI) is used as a noninvasive way to accurately estimate iron deposition levels in the liver as well as heart, joints, and pituitary gland. Treatment edit Phlebotomy /venesection: routine treatment consists of regularly scheduled phlebotomies ( bloodletting or erythrocytapheresis ). When first diagnosed, the phlebotomies may be performed every week or fortnight, until iron levels can be brought to within normal range.
9 The overwhelming majority depend on mutations of the hfe gene discovered in 1996, but since then others have been discovered and sometimes are grouped together as "non-classical hereditary haemochromatosis 10 "non-hfe related hereditary haemochromatosis 11 or "non-hfe haemochromatosis". 12 Most types of hereditary haemochromatosis have autosomal recessive inheritance, while type 4 has autosomal dominant inheritance. 13 Secondary haemochromatosis edit severe chronic haemolysis of any cause, including intravascular haemolysis and ineffective erythropoiesis (haemolysis within the bone marrow ) Multiple frequent blood transfusions 2 (either whole blood or just red blood cells which are usually needed either by individuals with hereditary anaemias. These include cirrhosis (especially related to alcohol abuse steatohepatitis of any cause, porphyria cutanea tarda, prolonged haemodialysis, and post- portacaval shunting diagnosis edit selective iron deposition (blue) in pancreatic islet beta cells(red). There are several methods available for diagnosing and monitoring iron loading.
Blood tests are usually the first test if there is a clinical suspicion of iron overload. Serum ferritin testing is a low-cost, readily available, and minimally invasive method for assessing body iron stores. However, the major problem with using it as an indicator of iron overload is that it can be elevated in a range of other medical conditions unrelated to iron levels including infection, inflammation, fever, liver disease, kidney disease, and cancer. Also, total iron binding capacity may be low, but can also be normal. 14 Serum ferritin : In males and postmenopausal females, a serum ferritin value of over 300 ng/mL (670 pmol/L) indicates iron overload. In premenopausal females, a serum ferritin value of over 150 15 or 200 16 ng/mL (330 or 440 pmol/L) 17 indicates iron overload. If the person is capable of showing the symptoms, they may need to be tested more than once throughout their lives as a precautionary, most commonly in women after menopause. Citation needed Transferrin saturation is a more specific test.

The most commonly affected joints are those of the hands, particularly the knuckles of the second and third fingers. 5, bronzing of the skin. This deep tan color, in concert with insulin insufficiency due to pancreatic damage, is the source of a nickname for this condition: "bronze diabetes". Causes and forms edit The causes can be distinguished between primary cases (hereditary or genetically determined) and less frequent secondary cases (acquired during life). 6 people of Celtic (Irish, Scottish, welsh, cornish, Breton etc. English, and Scandinavian origin 7 have a particularly high incidence of whom about make 10 are carriers of the C282Y mutation stadia on the hfe gene associated with hla-a3 which? and 1 have the condition. 8 Primary haemochromatosis edit Although it was known most of the 20th century that most cases of haemochromatosis were inherited, they were incorrectly assumed to depend on a single gene.
Iron overload (variously known as haemochromatosis, hemochromatosis, hemochromocytosis, celtic curse, irish illness, British gene, scottish sickness and bronzing diabetes) indicates accumulation of iron in the body from any cause. The most important causes are hereditary haemochromatosis (hhc a genetic disorder, and transfusional iron overload, which can result from repeated blood transfusions. 1 2, contents, meaning signs and symptoms edit, organs most commonly affected by haemochromatosis are the liver, heart, and endocrine glands. 3, haemochromatosis may present with the following clinical syndromes: 4, chronic liver disease and cirrhosis of the liver, heart involvement: heart failure, irregular heart rhythm. Hormonal issues: diabetes (see below) and hypogonadism (insufficiency of the sex hormone producing glands) which leads to low sex drive and/or loss of fertility in men and loss of menstrual cycle in women. Diabetes in people with iron overload occurs as a result of selective iron deposition in islet beta cells in the pancreas leading to functional failure and cell death. Arthritis, from calcium pyrophosphate deposition in joints leading to joint pains.
