Anticentromere antibody in primary biliary cirrhosis.

Anticentromere antibody in primary biliary cirrhosis.

An autoantibody specific for the centromere region of chromosomes and recently detected in the serum of patients with scleroderma was found in ther serum of 10 (9.1%) of 110 consecutive patients presenting with primary biliary cirrhosis. It was found exclusively among those with scleroderma, giving a prevalence of 50% in that group, and all patients with telangiectasia or calcinosis had the ant...

Long-term outcomes in antimitochondrial antibody negative primary biliary cirrhosis.

OBJECTIVES Antimitochondrial antibodies (AMA) are a sensitive and specific marker for primary biliary cirrhosis (PBC). AMAs are present in 95% of patients with PBC. However, 5% do not have AMAs and data on these patients is scarce. We aim to evaluate the long-term outcomes of patients with AMA negative PBC. METHODS A retrospective chart review of 71 AMA negative PBC patients. Disease presenta...

Is mitochondrial antibody diagnostic of primary biliary cirrhosis?

In a series of 218 patients diagnosed as having primary biliary cirrhosis only nine exhibited a negative serum mitochondrial antibody. On examining additional specimens from these patients, seven were found to be positive, giving a final incidence of greater than 99%. The two patients whose sera remained negative for the mitochondrial antibody had liver histology compatible with the diagnosis o...

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...
