Primary biliary cholangitis (PBC), previously known as primary biliary cirrhosis, is an autoimmune disease of the small bile ducts of the liver.[2] The most common symptoms are tiredness, itching, and yellowish skin and eyes.[1] The disease may worsen over decades.[5] Complications may include cirrhosis, liver failure, high blood cholesterol, and fat soluble vitamin deficiencies.[2]

Risk factors include a family history of the disease.[2] It is also associated with a number of other autoimmune diseases including autoimmune hepatitis, celiac disease, Raynaud disease, and scleroderma.[2] The underlying mechanism involves a slow, progressive destruction of the small bile ducts of the liver, causing bile and other toxins to build up and damage the liver.[2] Diagnosis is often based on blood tests, such as anti-mitochondrial antibodies and alkaline phosphatase, or a liver biopsy.[4]

Initial treatment is generally with ursodeoxycholic acid (UDCA) which slows the progression of the disease.[5] Obeticholic acid (OCA) may also be used.[5] Other efforts revolve around the management of complications.[3] In those who develop liver failure, a liver transplant may be indicated.[5]

PBC affects around 1 in 2,500 to 1 in 52,000 people.[6] It occurs 9 times more often in women than men.[3] Those between the ages of 30 and 60 are most commonly affected.[3] It has been described since at least 1851 and was named "primary biliary cirrhosis" in 1949.[7][8] As cirrhosis is a feature only of advanced disease, a name change to "primary biliary cholangitis" was accepted in 2014.[9][10][11]
