Ulcerative colitis (UC) is an incurable, immune-mediated inflammatory disease of the large bowel that typically requires long term immunosuppressive drugs to induce and maintain remission. Hospitalisation due to severe, uncontrolled disease is a common occurrence and estimated to affect up to 25% of UC patients. Janus kinase inhibitors (JAKi) have attracted considerable attention as potential candidates for treating hospitalised patients with severe UC and are increasingly used in this setting. For tofacitinib, there are accumulating data supporting their use as effective induction agents to prevent colectomy and reduce length of hospitalisation, however, these are limited to small case series and small cohort studies only. There are no published data for the use of filgotinib and upadacitinib for treating severe inpatient colitis. The aim of this study is to develop a large retrospective cohort of JAKi-treated hospitalised UC patients to describe the safety and effectiveness of using JAKi in this setting.
