Managing Acute Severe Ulcerative Colitis in 2025 and Beyond.

purpose of reviewAcute severe ulcerative colitis (ASUC) remains a high-risk condition with suboptimal clinical outcomes despite advancements in diagnostics, prognostication, and therapies. This review synthesizes recent evidence to address critical gaps in care, focusing on optimizing medical strategies to reduce colectomy rates and improve patient outcomes. RECENT

findingsRecent studies have identified novel biomarkers and predictive models for stratifying patients as high-risk for colectomy. Several emerging therapeutic strategies to optimize care have also been explored. Intensified infliximab dosing has not consistently shown improved clinical outcomes across all patients with ASUC, though it may benefit a subset of patients with unfavorable pharmacokinetics. Furthermore, Janus kinase inhibitors have shown promise in reducing colectomy rates, offering a potential alternative for select patients; however, supporting evidence remains preliminary. Despite these advancements, colectomy remains exceedingly common but continues to serve as a critical intervention to reduce complications and mortality. This underscores the therapeutic efficacy ceiling that still exists in our current approach to ASUC in 2025. Modern ASUC management prioritizes rapid risk stratification (using clinical, endoscopic, and biomarker data) and patient-tailored advanced therapy selection. Future strategies should focus on conducting rigorous trials of emerging agents in comparison to our current protocols, while integrating real-time, personalized, and dynamic prognostic tools to reduce heterogeneity in treatment response.
