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 .
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 ]
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).
In primary biliary cholangitis, there is fibrosis around the bile duct, the presence of granulomas and pooling of bile. [100] Lastly in alcoholic cirrhosis, there is infiltration of the liver with neutrophils. [97] Macroscopically, the liver is initially enlarged, but with the progression of the disease, it becomes smaller.
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 ...
SSC is a sclerosing cholangitis with a known cause. Alternatively, if no cause can be identified, then primary sclerosing cholangitis is diagnosed. SSC is an aggressive and rare disease with complex and multiple causes. It is characterized by inflammation, fibrosis, destruction of the biliary tree and biliary cirrhosis.
biliary dyskinesia; ICD-10 code K83: other diseases of the biliary tract: cholangitis (including ascending cholangitis and primary sclerosing cholangitis) obstruction, perforation, fistula of biliary tract (bile duct) spasm of sphincter of Oddi; biliary cyst; biliary atresia
