ObjectiveTo evaluate the efficacy and safety of ustekinumab in the treatment of oral ulcers (OU) in patients with Behçet's disease (BD).Patients and methodsProspective study including 14 patients [median age of 39 (34; 41) years, with 71% of men] fulfilling criteria of the International Study Group for BD and with active OU resistant to colchicine. Patients received ustekinumab 90 mg (n = 11) or 45 mg (n = 3) subcutaneously at inclusion, at week 4, and every 12 weeks. The primary efficacy endpoint was the proportion of patients with complete response (CR), defined as no oral ulcer, at week 12.ResultsAt week 12, 64% were in CR, 21% in partial response and 14% non-responders. The median number of OU decreased from 2 [2; 4] to 1 [0; 1.25] (p = 0.0005) at week 12. Mean change from baseline to week 12 of Behçet's syndrome activity score (BSAS) was 22.8 ± 0.3 (p = 0.01). The median daily corticosteroids dose decreased from 12.5 (10; 16.3) to 5 [5; 10] mg/day (p = 0.02). Three patients reported headaches, leading to discontinuation of ustekinumab in one case. After a median follow-up of 7 [3; 12] months, 10 (71%) patients were still receiving ustekinumab and four (28%) experienced a relapse. Decreased levels of circulating IL-17 and IL-12 [median [IQR]; 3.9 [1.6; 10.6] vs. 29.2 [25.2; 42.7] pg/ml, and 29.4 [23.1; 33.3] vs. 56.1 [51.1; 64.4] pg/ml, p = 0.008 for both] were observed under ustekinumab, respectively.ConclusionUstekinumab seems to be efficient and safe for patient with BD and refractory OU although relapses are frequent.
