Primary biliary cholangitis (PBC; formerly known as primary biliary cirrhosis) is an autoimmune liver disorder characterized by the progressive destruction of intrahepatic bile ducts, leading to cholestasis, cirrhosis, and liver failure.
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.
Overview. Claudia O. Zein, MD. The term cholestasis originally derives from the Greek and literally means “a standing still of bile.” This disruption of bile flow can occur on a cellular level in the hepatocyte, at the level of the intrahepatic biliary ductules, or from an extrahepatic mechanical obstruction of the bile ducts.
Primary Biliary Cholangitis (PBC) is considered an autoimmune disease because of its hallmark serologic signature, antimitochondrial antibody (AMA), and specific bile duct pathology. The etiology of PBC is thought to be due to a combination of genetic risk factors and environmental triggers.
Preamble. This American Association for the Study of Liver Diseases (AASLD) 2018 Practice Guidance on Primary Biliary Cholangitis (PBC) is an update of the PBC guidelines published in 2009.

Aug 27, 2015 · Introduction. Primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) are the two most common chronic cholestatic liver diseases. The prevalence of PBC ranges between 1.9 and 40.2 per 100,000 inhabitants, and may be rising, whereas the prevalence of PSC is as high as 16.2 per 100,000 inhabitants.
