Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress, as elevated intracellular iron levels increase free radical formation via the Fenton reaction.
The most common type is iron-deficiency anemia, in which a lack of iron leads to a reduction in the number of red blood cells or hemoglobin. This can impair oxygen transport throughout the body.
Serum ferritin 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 hemosiderosis is that it can be elevated in a range of other medical conditions unrelated to iron levels including infection, inflammation, fever, liver disease, renal disease ...
Normally, HFE facilitates the binding of transferrin, which is iron's carrier protein in the blood. Transferrin levels are typically elevated at times of iron depletion (low ferritin stimulates the release of transferrin from the liver). When transferrin is high, HFE works to increase the intestinal release of iron into the blood.
Because pregnancy and menstruation can take tremendous amounts of iron from the body, “women who are in their reproductive years should be eating extra foods with iron,” says Nance.
Deferoxamine can be administered intramuscularly as a single dose where it then binds to free iron in the blood and is excreted into the urine turning it to a "brick orange" or pink/red/orange color. [ 4 ] [ 8 ] Radiographs are no longer used for diagnosis due to the lack of connection between severity of iron toxicity and the presence of ...
An analysis of data from more than 8,000 adults in the U.S. revealed that 14% had low iron blood levels, a condition known as absolute iron deficiency, while 15% had the right iron levels but ...
Phlebotomy, the removal of blood from the body, is the main treatment for juvenile hemochromatosis. One unit of blood, the amount typically given during blood donation, is typically removed per session, and it is generally recommended that this be done once weekly until acceptable levels of iron are in the blood, which may take years.
