S100B was higher (in the sample 72 hours after admission) in patients who progressed to BD. The median S100b levels in BD were significantly higher than those in the non-BD group (10.4 (IQR: 0.4-16.5) ng/mL versus 0.9 (IQR: 0.3-4.3) ng/mL, p=0.040). This evidence concerns the gene S100B and Behcet disease.
