dc.description.abstractPurpose: To study HLA-B27circle plus and HLA-B27O patients with AAU with respect to the frequency and specificity of organ-specific and non-organ-specific autoantibodies. Methods: Fifty-seven consecutive patients with AAU were subjected to ophthalmologic and rheumatologic evaluation as well as to autoantibody determination: antinuclear antibodies (ANA), rheumatoid factor (RF), anticardiolipin, anti-smooth muscle, and anti-parietal cell antibodies, and immunoblot for antibodies to HeLa cells and to bovine iris extract. HLA-B27 was determined by a microlymphocytotoxicity assay. Statistical analysis employed chi-square test, Fisher's exact test, and McNemar test. Results: Thirty-four patients had the HLA-B27 allele (B27circle plus/AAU) and 23 did not (B27O/AAU). ANA, RF, anticardiolipin, and anti-parietal cell antibodies appeared in low frequency. No patient presented anti-smooth muscle antibody. Immunoblot showed a high frequency of antibodies to HeLa cell proteins in B27O/AAU patients with predominant reactivity at 46 kDa and 56kDa. in contrast, sera from B27circle plus/AAU patients reacted poorly against HeLa cell antigens. Immunoblot with bovine iris extract showed a significant frequency of antibodies in both groups, with a predominant response to antigens with an estimated mobility of 35, 52, and 54 kDa. Conclusion: Antibodies specific to iris antigens were equally frequent in both acute uveitis groups, whereas non-organ-specific autoantibodies, especially those to HeLa cell proteins, were far less frequent in B27circle plus/AAU than in B27O/AAU patients.en
