Hepatitis In hemochromatosis, excess amounts of iron accumulate in multiple body sites, including the liver, which can lead to cirrhosis. In Wilson's disease, excess amounts of copper accumulate in the liver and brain, causing cirrhosis and dementia. When the liver is involved, alpha-1-antitrypsin deficiency and Wilson's disease tend to present as hepatitis in the neonatal period or in childhood. Hemochromatosis typically presents in adulthood, with the onset of clinical disease usually after age 50. Ischemic hepatitis (also known as shock liver) results from reduced blood flow to the liver as in shock, heart failure, or vascular insufficiency. The condition is most
Copper in health their associated proteins are enabling scientists to understand how human bodies use copper and why it is important as an essential micronutrient. The diseases arise from defects in two similar copper pumps, the Menkes and the Wilson Cu-ATPases. The Menkes ATPase is expressed in tissues like skin-building fibroblasts, kidneys, placenta, brain, gut and vascular system, while the Wilson ATPase is expressed mainly in the liver, but also in mammary glands and possibly in other specialized tissues. This knowledge is leading scientists towards possible cures for genetic copper diseases. Menkes disease, a genetic condition of copper deficiency, was first described by
