Night blindness in primary biliary cirrhosis

Vitamin A treatment for night blindness in primary biliary cirrhosis.

Three patients with late stage primary biliary cirrhosis were found to have appreciable night blindness. Serum vitamin A concentrations were low in all three patients despite regular intramuscular supplementation in two. All patients responded dramatically to high dose oral supplementation, with full recovery of adaptation to dark and visual fields. Oral rather than intramuscular vitamin A supp...

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...

Primary biliary cirrhosis.

Primary biliary cirrhosis (PBC) is a chronic, cholestatic liver disease that is characterized by progressive immune mediated destruction of the intrahepatic bile ducts. Over time, fibrosis extends out of the portal tracts and progresses to cirrhosis. Neither the etiology nor the pathogenesis are well understood; however, most of the current evidence suggests that it is an autoimmune condition t...
