The case report presents a novel therapeutic option in acute severe ulcerative colitis which remains a life-threatening and challenging scenario in clinical gastroenterology. It emphasizes the potential of upadacitinib, a JAK1 selective JAK inhibitor, as a medical rescue option in this situation and will be of great interest to the readers of the Research Topic which deals with Advances in Therapy in Inflammatory Bowel Diseases. As there is a lack of therapeutic options in acute severe ulcerative colitis, upadacitinib appears to be a very valuable therapeutic option. The original aspects of our case report are 1. that both reported patients suffered from fever prior to start of upadacitinib treatment, 2. that upadacitinib was used after steroid and infliximab failure, and 3. that we provide a one-year follow-up for one of the patients.
