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.
[1] [4] In cases where high doses of elemental iron have been ingested and the patient is exhibiting signs and symptoms of severe systemic iron poisoning, supportive care measures like volume resuscitation and deferoxamine should be initiated immediately. [4] A quick response to iron poisoning can significantly improve clinical outcomes.
Haemochromatosis is protean in its manifestations, i.e., often presenting with signs or symptoms suggestive of other diagnoses that affect specific organ systems.Many of the signs and symptoms below are uncommon, and most patients with the hereditary form of haemochromatosis do not show any overt signs of disease nor do they have premature morbidity, if they are diagnosed early, but, more ...
Hemosiderin deposition in the liver is a common feature of hemochromatosis and is the cause of liver failure in the disease. Selective iron deposition in the beta cells of pancreatic islets leads to diabetes [4] [2] due to the distribution of transferrin receptor on the beta cells of islets [3] and in the skin leads to hyperpigmentation.
Before iron deficiency anemia sets in, “the body will do everything it can to retain the right number of red blood cells. So, it will deplete the storage iron before it depletes the red blood ...
Iron metabolism disorders may involve a number of genes including HFE and TFR2. [ 1 ] Hepcidin is the master regulator of iron metabolism and, therefore, most genetic forms of iron overload can be thought of as relative hepcidin deficiency in one way or another [1] .
A heated blanket or heating pad might keep you warm in the cold winter months, but experts are warning of a potential danger. Too much close exposure to high heat can cause noticeable skin damage ...
