Abstract
BACKGROUND
Behcet's disease is an inflammatory vasculitis, and pathergy reaction is a compulsory element of the diagnostic criteria. In the literature, there is no study comparing the histopathology of negative pathergy tests and positive pathergy tests in newly diagnosed Behcet's patients. The primary goal was to investigate the frequency of vasculitis, which is an important finding of Behcet's disease, in pathergy histopathology.
METHODS
The histopathology of patients with positive and negative pathergy tests revealed vasculitis or vasculopathy. In histopathology, neutrophils, lymphocytes, eosinophils, and mast cells in the perivascular area were counted and recorded as a percentage.
RESULTS
Of the 88 Behcet's patients who participated in the study, 45 were female and 43 were male. The rate of vasculitis in the histopathology of those who were positive for the pathergy test was not statistically different than those of those with negative pathergy tests (P = .14). In our study, although the relationship between the male gender and uveitis was significant at the border, and the relationship between pathergy positivity and uveitis was not found to be significant, a significant relationship was found between vasculitis in histopathology and uveitis (P = .023).
CONCLUSIONS
Based on the results of our study, we think that a pathergy test of histopathology will contribute to the clinical diagnostic evaluation in cases with suspicious clinical pathergy tests and especially in cases with negative pathergy tests.
