Autoimmune hepatitis is a disease in which the body’s own immune system attacks the liver and causes it to become inflamed. If untreated, it can lead to cirrhosis and liver failure.
Primary biliary cholangitis (PBC) is a chronic liver disease resulting from progressive destruction of the intrahepatic bile ducts in the liver.
Bile ducts become blocked due to inflammation and scarring or fibrosis, accumulating in the liver, where it gradually damages liver cells and causes cirrhosis, or fibrosis of the liver.
