Are the specific and nonspecific ANA staining patterns of Behcet's Disease patients important?

Abstract

Background: The autoinflammatory character of Behcet's Disease has led researchers to investigate the role of autoantibodies. However, no significant positive result has been reported for autoantibody tests for the disease. Aims: To investigate the specific and nonspecific staining patterns of Behcet's Disease (BD) patients.Methods: 140 patients (87 females, 53 males) with an average of 41.9 +/- 3 years who were being followed up for Behcet's Disease, and a control group consisting of a total of 736 (464 females, 272 males) healthy volunteers made up of blood donors without any disease whose average age was 50.2 +/- 4 years were included in the study. Peripheral venous blood was collected from the patients and the sera were separated. Patient sera were studied by indirect immunofluorescence antibody test (IFA) at a dilution of 1/40 and 1/100. Results: A total of 140 (87 females, 53 males) Behcet's Disease patients and 736 (464 females, 272 males) healthy controls were examined. The rate of ANA positivity was 11.6% in the control group and 10.7% in the Behcet's Disease group. In general, no difference was detected between the patients and the healthy controls in terms of autoantibody positivity (p > 0.05). However, when examined in terms of patterns, the low detection of DFS70 and the observation of centriole staining type patterns in Behc , et's Disease patients was noteworthy (p < 0.05). Conclusion: Autoantibody tests, which hold an important place in classic autoimmune diseases, are not necessary for Behcet's patients, but they should be examined in terms of nonspecific patterns.
