Vedolizumab for the Management of Refractory Behçet's Disease: From a Case Report to New Pieces of Mosaic in a Complex Disease.

OBJECTIVES

When treating Behçet's disease (BD), anti-tumor necrosis factor (TNF)-α agents have become a second-line therapy when conventional immunosuppressive drugs have failed. However, in the case of failure of treatment with anti-TNFα drugs, further options are limited. Based on previous reports of the efficacy of vedolizumab (VDZ) in inflammatory bowel diseases, we decided to administer VDZ to treat a patient with intestinal BD.

METHODS

We present the case of a 49-year-old female patient with BD. Her clinical manifestations included erythema nodosum, oro-genital ulcers, positive Pathergy test, positive HLA-B51, and biopsy-proven intestinal BD. The patient was unsuccessfully treated with conventional immunosuppressive and several biological agents.

RESULTS

Treatment with VDZ was started intravenously at a dose of 300 mg at 0, 2, and 6 weeks and then every 4 weeks. After the second dose of VDZ, the patient reported a marked improvement of intestinal BD and a concomitant amelioration of arthralgia, erythema nodosum lesions and aphthosis. Clinical remission was achieved at 6 months after starting VDZ.

CONCLUSION

VDZ might represent a valid option to treat patients with BD who are non-responsive to standard treatments or anti-TNFα agents, particularly, those cases with intestinal involvement.
