Abstract

Biological therapy dramatically changed the management of Ulcerative Colitis (UC). However, a significant number of these patients fail to respond or have secondary loss of response to this strategy. In this clinical situation, the options include intensification of anti-TNF therapy, the use of a second anti-TNF or being switched to another drug class. Among the later, tofacitinib, an oral small molecule directed against the JAK/STAT pathway, is safe and effective in inducing and maintaining remission in patients with moderate-severe UC. We report two patients with UC refractory to conventional treatment and biological therapy, who responded successfully to the use of tofacitinib.
