The X-factor in primary biliary cirrhosis: monosomy X and xenobiotics

Primary biliary cirrhosis: does X mark the spot?

Primary biliary cirrhosis (PBC) is an autoimmune disease of unknown etiology leading to progressive destruction of intrahepatic bile duct, with cholestasis, cirrhosis, and eventually liver failure. Epidemiological data indicate that environmental factors trigger autoimmunity in genetically susceptible individuals, although no definitive association of PBC with specific genes has been found. Fur...

Infectious Agents and Xenobiotics in the Etiology of Primary Biliary Cirrhosis

Primary biliary cirrhosis (PBC)is a chronic autoimmune cholestatic liver disease that manifests a latitudinal gradient in prevalence and incidence. The mechanisms leading to the initiation and perpetuation of PBC remain largely enigmatic, although it is established that a combination of genetic predisposition and environmental stimulation is required. PBC is also characterized by a high concord...

Asymptomatic primary biliary cirrhosis.

Primary biliary cirrhosis.

Primary biliary cirrhosis is a chronic liver disease characterised by intrahepatic bile-duct destruction, cholestasis, and, in some cases, cirrhosis. Evidence supporting the autoimmune nature of this disorder includes the appearance of highly specific antimitochondrial antibodies (AMAs) and autoreactive T cells. Concordance rates in monozygotic twins, familial prevalence, and genetic associatio...

Primary Biliary Cirrhosis

Primary Biliary Cirrhosis (PBC) is the result of long-standing damage to intra-hepatic biliary channels as a result of immune mechanisms leading to cholestasis and its associated complications. It can end up in chronic liver disease or cirrhosis. It usually manifests as pruritis that then proceeds to fatigue, jaundice and other features of chronic liver disease. It is detected by raised serolog...
