Dramatic Deep and Durable Remission of Acute Fulminant Ulcerative Colitis Achieved with Cyclosporine in a Patient Who Failed the Induction Intravenous Phase of Cyclosporine

Medical rescue therapy for patients with severe steroid-refractory ulcerative colitis (UC) consists of intravenous (IV) cyclosporine or infliximab and remains limited. Cyclosporine is used by fewer medical facilities due to comfort and need for close drug level monitoring, despite evidence that it can have dramatic benefits. In many tertiary centers it is accepted that after 3–7 days of treatment with IV cyclosporine without response, a patient will not respond to the therapy, and other modalities, namely surgery, should be considered. We present the case of a 36-year-old man with acute severe UC refractory to steroids and multiple biologics, who “failed” IV cyclosporine for 2 weeks, much longer than the usually accepted induction phase, and achieved remission with continuation of oral cyclosporine. This case demonstrates the possibility that continued therapy with cyclosporine for a longer duration than the currently accepted timeline can lead to remission and avoidance of colectomy in properly selected and monitored patients.
