Background/Purpose: Behçet’s disease (BD) is a systemic, chronic, relapsing vasculitis with no pathognomonic diagnostic test. The most widely used classification criteria are those of the International Study Group (ISG) for BD. These criteria were repeatedly found to have low sensitivity. Therefore, the International Criteria for Behçet’s Disease (ICBD) were published in 2014.
Objectives: To compare the ISG with ICBD diagnostic criteria for BD.
Methods: The study included all consecutive 111 patients diagnosed with definitive or possible BD by expert rheumatologists. They were diagnosed at a well-defined population in Northern Spain between 1980 and 2019. The ISG and ICBD diagnostic criteria for BD were applied to and compared among all patients.
Results: We studied 111 patients (62 Women/49 Men), mean age 36.8±13.2 years. BD was diagnosed in 65 (58.5%) by ISGBD criteria and in 86 (77.5%) by ICBD criteria. No significant differences were observed between both criteria (p < 0.001). The overall concordance was fair (Kappa 0.3; p< 0.001). Sensitivity was 58.6% for ICBD criteria and 80.2% for ISG. (TABLE-1)
Conclusion: ICBD criteria exhibit higher sensitivity than ISG criteria. Thus, the application of these new criteria can achieve a more correct and earlier diagnosis of BD.
