Long-term Outcome After Admission for Acute Severe Ulcerative Colitis in Oxford: The 1992-1993 Cohort

Abstract

Background: To determine the long-term Outcome of patients admitted with acute Severe colitis (ASC) who avoided colectomy on the index admission, a retrospective cohort study was performed. Methods: Patients admitted for intensive treatment of ASC in 1992-1993 previously described for a predictive index of short-term Outcome in severe ulcerative colitis (UC) were followed for a median 122 months (range 3-144). Complete responders (CR) to intensive therapy had LT 3 nonbloody stools/day on day 7 of the index admission; incomplete responders (IR) were all others who avoided colectomy oil that admission, Main outcome measures were colectomy-free survival, time to colectomy, and duration of steroid-free remission. Results: In all, 6/19 CR (32%) came to colectomy compared to 10/13 IR (P = 0.016; relative risk 3.33, 95% confidence interval [CI] 1.12-9.9). The median +/- interquartile range time to cotectomy was 28 +/- 47 months (range 6-99) for CR who came to colectomy versus 7.5 +/- 32 (3-72) months for IR (P = 0.118). Among the IR, 7/13 came to colectomy within 12 months, and all within 6 years From the index admission. The longest period of steroid-free remission was 42 +/- 48 (0-120) months for CR, but 9 +/- 20 (1-35) months for IR (P = 0.011). Conclusions: One week after admission with ASC in the prebiologic era. IRs had a 50% chance of colectomy within a year and 70% within 5 years, despite cyclosporin and azathioprine where appropriate. The maximum duration of remission in CRs was almost 5 times longer than IRs. It is unknown whether biologics change the long-term Outcome.
