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 .
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).
Cholestatic pruritus is the sensation of itch due to nearly any liver disease, but the most commonly associated entities are primary biliary cholangitis, primary sclerosing cholangitis, obstructive choledocholithiasis, carcinoma of the bile duct, cholestasis (also see drug-induced pruritus), and chronic hepatitis C viral infection and other forms of viral hepatitis.
The differential diagnosis can include primary biliary cholangitis (formerly referred to as primary biliary cirrhosis), drug-induced cholestasis, cholangiocarcinoma, IgG4-related disease, post-liver transplantation nonanastomotic biliary strictures, [23] and HIV-associated cholangiopathy. [24]
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 ...

Chronic cholestasis occurs in primary biliary cholangitis (PBC). PBC is a progressive autoimmune liver disease in which small intrahepatic bile ducts are selectively destroyed, leading to cholestasis, biliary fibrosis, cirrhosis, and eventually liver failure that requires transplantation.
In primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC), some use a modified Child–Pugh score where the bilirubin references are changed to reflect the fact that these diseases feature high conjugated bilirubin levels. The upper limit for 1 point is 68 μmol/L (4 mg/dL) and the upper limit for 2 points is 170 μmol/L (10 ...
