Management of acute severe ulcerative colitis-an update for generalist and specialist clinicians

Acute severe ulcerative colitis (ASUC) is a potentially life-threatening medical emergency that occurs in up to 25% of patients with ulcerative colitis. Although intravenous corticosteroids remain the cornerstone of therapy, 30-40% of patients will not respond and need timely consideration of rescue therapy with (currently) either infliximab or ciclosporin or indeed colectomy, underscoring the importance of multidisciplinary care to ensure favourable outcomes for patients. We discuss the current evidence and present an approach to the management of ASUC for general and specialist clinicians caring for patients with ASUC.

The information in this review is derived from data published in peer- reviewed academic journals and registered clinical trials.

Management of acute severe colitis requires a multidisciplinary approach with early initiation with steroids and timely escalation of treatment to either medical rescue therapy or surgery.

Balancing the risks of delayed surgery vs. optimizing medical therapy, including accelerated dosing schedules for biologics, remains ambiguous.

The position on newer molecules like Janus Kinase inhibitors, such as tofacitinib, is a growing area with early real-world data showing promise for steroid refractory ASUC.

Developing predictive biomarkers and clinical risk scores for personalized rescue therapy selection is an evolving area of research.
