Rescue therapies for steroid-refractory acute severe ulcerative colitis: A review.

Although cyclosporine and infliximab still represent the mainstays of salvage therapy for steroid-refractory ASUC, new therapeutic agents may also play a role. Tofacitinib, due to its rapid effect, is an attractive therapeutic rescue option. Vedolizumab and ustekinumab, as maintenance therapy in combination with the fast-acting cyclosporine as induction therapy, may represent a promising bridging strategy, especially in patients with previous failure to thiopurines and/or anti-TNF agents.
