| Popis: | Background The efficacy of Infliximab and Cyclosporin A as medical rescue therapy in patients with corticosteroid refractory acute severe ulcerative colitis (ASUC) is well established. We aimed to identify predictors of failure of medical rescue therapy and colectomy during the same admission in this population. Methods Patients hospitalized with ASUC who received infliximab or cyclosporin A after failing intravenous corticosteroid therapy between 1st January 2013 to 31stJuly, 2020 at two Australian tertiary IBD centres were retrospectively analysed. Patients who underwent colectomy during the same admission after medical rescue therapy were defined as non-responders. Logistic regression analysis was performed to identify predictors of colectomy during same admission. Results 226 episodes of ASUC [110 (48.7%) female, median disease duration 2 years] were analysed. 104 (46%) episodes required rescue therapy [94 episodes received medical rescue (16 cyclosporine/78 Infliximab) and 10 underwent direct colectomy]. In patients receiving medical rescue therapy, 16 (17%) underwent colectomy during same admission and 28 (29.8%) underwent colectomy by 12 months. On multivariable analysis, UCEIS score at admission [Coef 0.100 (0.02-0.17), p 0.011] and CRP on Day 3 post-rescue therapy [Coef 0.004 (0.0007-0.007), p 0.018] were significant for predicting colectomy during the same admission. A score with 1 point for each variable (UCEIS score ≥ 7 and CRP value of ≥ 22 mg/L on day 3 post medical rescue therapy) was developed. A score of 2 points had sensitivity 57%, specificity 97%, PPV 80%, NPV 91%, accuracy 89% for predicting colectomy during the same admission and sensitivity 33%, specificity 94%, PPV 80%, NPV 67%, accuracy 69% for predicting colectomy at 12 months. Conclusion UCEIS and CRP on day 3 after rescue therapy are predictors of non-response to medical rescue therapy and need for colectomy during the admission for the ASUC episode. Combination of UCEIS ≥ 7 and CRP ≥ 22mg/L on day 3 post medical rescue therapy has a PPV of 80% for colectomy during same admission and at 12 months. The score can be used to make decisions about colectomy or further medical rescue therapy. |
