Ischemic hepatitis, also known as shock liver, is a condition defined as an acute liver injury caused by insufficient blood flow (and consequently insufficient oxygen delivery) to the liver. [5] The decreased blood flow ( perfusion ) to the liver is usually due to shock or low blood pressure.
Late complications of cirrhosis or liver failure include portal hypertension (high blood pressure in the portal vein due to the increased flow resistance through the damaged liver), coagulation disorders (due to impaired production of coagulation factors), ascites (heavy abdominal swelling due to buildup of fluids in the tissues) and other ...
Hepatotoxicity (from hepatic toxicity) implies chemical-driven liver damage. Drug-induced liver injury (DILI) is a cause of acute and chronic liver disease caused specifically by medications and the most common reason for a drug to be withdrawn from the market after approval.
Ballooning degeneration – hepatocytes in the setting of alcoholic change often swell up with excess fat, water and protein; normally these proteins are exported into the bloodstream. Accompanied with ballooning, there is necrotic damage. The swelling is capable of blocking nearby biliary ducts, leading to diffuse cholestasis. [6]
The liver plays a vital role in many metabolic processes in the body including protein synthesis, detoxification, nutrient storage (such as glycogen), platelet production and clearance of bilirubin. With progressive liver damage; hepatocyte death and replacement of functional liver tissue with fibrosis in cirrhosis, these processes are disrupted.
The complications are hepatic encephalopathy and impaired protein synthesis (as measured by the levels of serum albumin and the prothrombin time in the blood). The 1993 classification defines hyperacute as within 1 week, acute as 8–28 days, and subacute as 4–12 weeks; [ 1 ] both the speed with which the disease develops and the underlying ...
Wilson's disease, a condition where copper builds up in the body, can be managed with drugs that bind copper, allowing it to be passed from the body in urine. [59] In cholestatic liver disease, (where the flow of bile is affected due to cystic fibrosis [60]) a medication called ursodeoxycholic acid may be given. [61]
In the 1970s and 1980s, blood transfusions were a major factor in spreading hepatitis C virus. [32] Since widespread screening of blood products for hepatitis C began in 1992, the risk of acquiring hepatitis C from a blood transfusion has decreased from approximately 10% in the 1970s to 1 in 2 million currently.
