The severity of hepatic encephalopathy is graded with the West Haven Criteria; this is based on the level of impairment of autonomy, changes in consciousness, intellectual function, behavior, and dependence on therapy. [4] [17] Grade 0 - No obvious changes other than a potentially mild decrease in intellectual ability and coordination
Cirrhosis is a late stage of serious liver disease marked by inflammation (swelling), fibrosis (cellular hardening) and damaged membranes preventing detoxification of chemicals in the body, ending in scarring and necrosis (cell death). [11] Between 10% and 20% of heavy drinkers will develop cirrhosis of the liver (NIAAA, 1993).
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.
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]
By using steroid-based drugs in autoimmune hepatitis. [57] Regularly removing a quantity of blood from a vein (venesection) in the iron overload condition, hemochromatosis. [58] 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]
Histopathology of shock liver, showing its hallmark [1] pathologic finding centrilobular necrosis but viable periportal hepatocytes. H&E stain. The necrotic hepatocytes have barely discernible nuclei. Symptoms: Mental confusion [2] Causes: Heart failure, Infection [3] Diagnostic method: Doppler ultrasound, Blood test [3] Treatment
Liver regeneration is the process by which the liver is able to replace damaged or lost liver tissue. The liver is the only visceral organ with the capacity to regenerate. [1] [2] The liver can regenerate after partial hepatectomy or injury due to hepatotoxic agents such as certain medications, toxins, or chemicals. [3]
The hepatocyte is a cell in the body that manufactures serum albumin, fibrinogen, and the prothrombin group of clotting factors (except for Factors 3 and 4). [ citation needed ] It is the main site for the synthesis of lipoproteins , ceruloplasmin , transferrin , complement , and glycoproteins .
