The objective of this study was to determine the concordance between the Iranian Behçet’s disease dynamic activity measure (IBDDAM) or the Behçet’s disease current activity form (BDCAF) and expert physician global assessment (PGA) in the evaluation of disease activity changes in Behçet’s disease (BD). In a prospective study, 117 consecutive patients with BD were evaluated in their two consecutive follow-up visits by IBDDAM and BDCAF. The change in disease activity was determined (increased, unchanged or decreased) according to the PGA. We used receiver operating characteristic (ROC) curve to determine an appropriate cutoff point for disease activity change. Comparison was made by Stata and kappa analysis. Comparing the area under the ROC curve showed a significant difference between IBDDAM and BDCAF (p < 0.03). The difference was more significant between nonocular IBDDAM and …
