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.
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 ...
Some individuals with the homozygous H63D variant may show signs of heart disease, cardiomyopathies, and disturbances in the calcium channels in particular. [20] [21] The homozygous H63D variant is an indicator of the iron metabolism disorder hemochromatosis, which may increase the risk of developing a fatty liver. [22]
Liver cancer can be primary in which the cancer starts in the liver, or it can be liver metastasis, or secondary, in which the cancer spreads from elsewhere in the body to the liver. Liver metastasis is the more common of the two liver cancers. [3] Instances of liver cancer are increasing globally. [8] [9]
High consumption of alcohol can lead to several forms of liver disease including alcoholic hepatitis, alcoholic fatty liver disease, cirrhosis, and liver cancer. [42] In the earlier stages of alcoholic liver disease, fat builds up in the liver's cells due to increased creation of triglycerides and fatty acids and a decreased ability to break ...
Treatment for hemochromatosis type 3 may include reducing iron levels by removing blood (phlebotomy), iron chelation therapy, diet changes, and treatment for complications of the disease. The purpose of the treatment is to reduce the amount of iron in the body to normal levels, prevent or delay organ damage from excess iron, and maintain normal ...
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 and cancer. While liver biopsies provide a direct measure of liver iron concentration, the small sample size ...
Inflammatory cytokines stimulate the liver to produce the iron metabolism regulator protein hepcidin, that reduces available iron. If hepcidin levels increase because of non-bacterial sources of inflammation, like viral infection, cancer, auto-immune diseases or other chronic diseases, then the anemia of chronic disease may result. In this case ...
