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.
Bile duct abnormalities (cholangitis, ductal injury, ductular reaction) can be seen and should prompt evaluation for primary biliary cholangitis or sarcoidosis if granulomas are observed. Plasma cell infiltrate, rosettes of hepatocytes, and multinucleated giant cells. Varying degrees of fibrosis (except in the mildest form of autoimmune hepatitis).
Anti-mitochondrial antibodies (AMA) are autoantibodies, consisting of immunoglobulins formed against mitochondria, [1] primarily the mitochondria in cells of the liver.. The presence of AMA in the blood or serum of a person may be indicative of the presence of, or the potential to develop, the autoimmune disease primary biliary cholangitis (PBC; previously known as primary biliary cirrhosis).
Primary sclerosing cholangitis is one of the major known risk factors for cholangiocarcinoma, [40] a cancer of the biliary tree, for which the lifetime risk among patients with PSC is 10-15%. [3] This represents a 400-fold greater risk of developing cholangiocarcinoma compared to the general population. [ 1 ]
Less common causes of cirrhosis include autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis that disrupts bile duct function, genetic disorders such as Wilson's disease and hereditary hemochromatosis, and chronic heart failure with liver congestion. [13]
Human betaretrovirus (HBRV) has been extensively studied in its connection to the autoimmune liver disease, primary biliary cholangitis (PBC). [3] Various research approaches have been employed, including in vitro HBRV co-cultivation studies using biliary epithelium, the use of autoimmune biliary disease mouse models with MMTV infection and the ...
