Primary biliary cirrhosis is a classical autoimmune liver disease and is present in around 1 in 1,000 women over the age of 40. It has a number of diagnostic characteristics consistent with autoimmune liver injury, in particular, the high specificity of circulating anti-mitochondrial antibodies. Histologically, the disease is reflected as a granulomatous lymphocytic cholangitis that consequently leads to small bile duct loss and cholestasis. Progressive disease is characterised by the development of a biliary cirrhosis, with end-stage features of liver disease ultimately impacting patient outcomes. Studies support a combination of environmental and genetic risk factors that coalesce to lead to loss of immunological tolerance and persistent biliary inflammation. Significant advances have occurred recently in understanding the genetic risk factors for disease, as well as utilising human and murine studies to characterise the nature of the biliary injury and cholestatic response.
