Clinical Scenario

This protocol applies to patients with acute severe ulcerative colitis presenting with more than six bloody stools per day plus at least one systemic sign of toxicity: tachycardia, fever, anemia (hemoglobin <10.5 g/dL), or elevated ESR (>30 mm/h) or CRP (>30 mg/L) — who have not responded to initial intravenous corticosteroid therapy.

Prior Treatment — Response Criteria Not Met

Intravenous corticosteroids (methylprednisolone or hydrocortisone) were administered as the initial rescue measure. By day 3–5 of treatment, the patient did not achieve the expected response: bowel movements remained at eight or more per day, CRP remained at 45 mg/L or above, ESR remained at 75 mm/h or above, fever persisted, or colonic dilation was present on imaging. Failure to meet these thresholds triggers escalation to the next treatment line.

Next-Line Rescue Approach

When IV steroids fail to achieve the above endpoints, medical rescue therapy with an intravenous agent becomes the next step — with the choice between available options guided by the treating provider. The full selection criteria, dosing algorithm, and monitoring targets are in the complete structured protocol.

Acute severe ulcerative colitis (ASUC), historically referred to as "fulminant" or "toxic" colitis, represents a severe form of acute colitis involving more than six bloody stools per day accompanied by at least one systemic sign of toxicity including tachycardia, fever, anemia (hemoglobin <10.5 g/dL), or elevated erythrocyte sedimentation rate (ESR) greater than 30 mm/h.

If patients fail to respond by 3 to 5 days of steroid therapy, medical rescue should be initiated using either infliximab or cyclosporine.

At this time, randomized control trial data show similar efficacy and complication profiles of each medication, and therefore selection is provider dependent.
