Why This Matters

The 1955 Truelove and Witts criteria do not account for patients already on modern outpatient therapies. Updated consensus criteria could change how ASUC is recognized and triaged in current clinical practice.

Who Should Pay Attention

Clinicians managing severe ulcerative colitis, IBD researchers planning validation studies or trials, and specialist IBD clinics updating diagnostic pathways.

What To Know

This is a modified Delphi consensus from international gastroenterologists aimed at updating the 1955 Truelove and Witts criteria so they account for current outpatient treatment patterns. The recommendations are consensus opinions, not validated diagnostic rules — the authors state these criteria need prospective validation.

The abstract reports agreed thresholds for clinical and laboratory markers (CRP, stool frequency, proportion of bloody stools, albumin, hemoglobin, heart rate, temperature, leukocyte count) and procedural guidance (endoscopic confirmation, CMV exclusion, radiology for toxic megacolon).

Keep In Mind

This is a consensus (Delphi) statement reported in the article abstract; the criteria are proposed and need prospective validation before being adopted as definitive diagnostic standards.
