“…1,2 Patients with severe symptoms are treated with intravenous corticosteroids as a first-line therapy with a response rate of approximately 60%. [3][4][5][6] Previous studies have determined some predictive indices of response to intravenous corticosteroids in patients with UC: Oxford Index consisting of stool frequency and C-reactive protein on the third day after corticosteroid administration, Sweden Index (fulminant colitis index) consisting of stool frequency and C-reactive protein on the third day after corticosteroid administration, and Ho Index consisting of serum albumin on the first day, transverse colon diameter on plain X-ray, and average stool frequency on the first to third days after corticosteroid administration (Table S1).
