  • Title: [Antinuclear antibodies in primary biliary cirrhosis].
    Author: Mzali S, Johanet C, Chrétien P, Abuaf N.
    Journal: Gastroenterol Clin Biol; 1989; 13(8-9):690-5. PubMed ID: 2680726.
    Abstract:
    Antinuclear and antinuclear membrane autoantibodies are detected by indirect immunofluorescence in sera of 62 p. 100 of primary biliary cirrhosis patients; when anti-SS-A (Ro) and anti-SS-B (La) autoantibodies were included, 70 percent of patients had at least one type of antinuclear antibody. Of 89 patients with primary biliary cirrhosis, 30 had either Raynaud's phenomenon, Sjögren's syndrome or the CREST syndrome. Some antinuclear antibodies, anticentromere and speckled S1 type, seem to correlate with the associated connective tissue disease. Antibodies showing the S3 pattern (multiple nuclear dots) and antibodies to nuclear membrane may be present independently of an association with connective tissue disease. In the classical technical conditions used to detect anti-tissue and anti-mitochondrial autoantibodies on tissue sections, antinuclear antibodies like anti-centromere or S3 may not be detected and/or identified. Primary biliary cirrhosis patient sera for antinuclear antibodies determination must be screened by at least two assays: indirect immunofluorescence on a human cell line, like HEp-2, and immunodiffusion. The last assay must be performed even if antinuclear antibodies are undetected by immunofluorescence.
