Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is an acute condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
Liver diseases, including conditions such as non-alcoholic fatty liver disease (NAFLD), alcohol-related liver disease (ALD), and viral hepatitis, are significant public health concerns worldwide. In the United States, NAFLD is the most common chronic liver condition, affecting approximately 24% of the population, with the prevalence rising due ...
Metabolic dysfunction–associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease (NAFLD), [a] is a type of chronic liver disease.This condition is diagnosed when there is excessive fat build-up in the liver (hepatic steatosis), and at least one metabolic risk factor.
Hepatotoxicity and drug-induced liver injury also account for a substantial number of compound failures, highlighting the need for toxicity prediction models (e.g. DTI), [2] and drug screening assays, such as stem cell-derived hepatocyte-like cells, that are capable of detecting toxicity early in the drug development process. [3]
This manifests as lipid peroxidation, mitochondrial damage, and glutathione (an endogenous antioxidant) depletion. [7] Damaged hepatocytes release Danger associated molecular patterns (DAMPs) which are molecules that lead to further activation of the immune system's inflammatory response and further hepatocyte damage. [7]
Several biochemical tests are useful in the evaluation and management of patients with hepatic dysfunction. These tests can be used to detect the presence of liver disease. They can help distinguish among different types of liver disorders, gauge the extent of known liver damage, and monitor the response to treatment.
Primary biliary cholangitis (PBC), previously known as primary biliary cirrhosis, is an autoimmune disease of the liver. [ 1 ] [ 2 ] [ 3 ] It results from a slow, progressive destruction of the small bile ducts of the liver, causing bile and other toxins to build up in the liver, a condition called cholestasis .
Risk factors known as of 2010 are: Quantity of alcohol taken: Consumption of 60–80 g per day (14 g is considered one standard drink in the US, e.g. 1 + 1 ⁄ 2 US fl oz or 44 mL hard liquor, 5 US fl oz or 150 mL wine, 12 US fl oz or 350 mL beer; drinking a six-pack of 5% ABV beer daily would be 84 g and just over the upper limit) for 20 years or more in men, or 20 g/day for women ...
