Clinical relevance of antiphospholipid antibodies in primary biliary cirrhosis.

2005

Primary biliary cirrhosis (PBC) is a cholestatic liver disease characterized by the presence of antimitochondrial autoantibodies (AMAs), but also with reactivities to other autoantigens. Recent studies showed that antibodies to phospholipids (APAs) represent an important group of autoantibodies identified in patients with PBC. In this study different types of APAs were identified in the sera of patients with PBC and autoimmune hepatitis (AIH) and control subjects. Sera from patients with PBC and AIH were tested for the presence of antibodies directed against cardiolipin (CL), phosphatidylserine (PS), and to beta(2)-glycoprotein I (beta(2)-GPI). Furthermore, an in-house test for antithrombop…
