Update on the Treatment of Behcet's Disease of the Small Bowel with Biologic Agents

The treatment of intestinal Behcet's disease (BD) is challenging, and one-third of patients require surgery due to failure of conventional therapies. Anti-tumor necrosis factor-α (TNF-α) and other new biologics have been actively investigated for managing intestinal BD. In this article, we review the updated experiences and up-to-date clinical data on anti-TNF-α and other biologics for the management of intestinal BD.

Recent prospective studies have proved the efficacy and safety of infliximab and adalimumab for treating intestinal BD. Recent studies with other biologics such as anti-interleukin (IL)-1 (anakinra and canakinumab) and anti-IL-6 (tocilizumab) have shown promising results in patients with systemic, including intestinal, BD. Both infliximab and adalimumab can be useful in managing patients with intestinal BD, especially severe or refractory cases, with a similar efficacy and safety profile. More evidence for anakinra, canakinumab, tocilizumab, anti-IL-17 (secukinumab), and anti-IL-12/23 (ustekinumab) in intestinal BD is required.
