Abstract

Abstract: Background: Acute severe ulcerative colitis (ASUC) is a potentially life-threatening event affecting up to 25% of patients during disease course. Intensive intravenous glucocorticoid treatment (IIVT) and early colectomy have reduced mortality to less than 2% in the last four decades. Rescue therapies -Infliximab (IFX) or Cyclosporin (CyA)- may reduce early colectomy in IIVT refractory patients but their impact in the long-term is unclear. Aim of the present study was to evaluate the long-term colectomy rate in patients escaping early colectomy after a severe attack Methods: From 2005 to 2016 all patients with ASUC meeting Truelove and Witts criteria modified by Chapman et al. referring to 14 Italian IBD referral centres were retrospectively reviewed. All patients received IIVT. IFX or CyA were used as rescue therapies. Primary outcome was long-term colectomy rate in patients escaping early colectomy (within 3 months). Secondary outcomes were overall need of escalation therapy (defined as need of anti-TNF agents or immunomodulators or steroids) or hospitalisation. Kaplan–Meier survival method was used to estimate the cumulative probability of a colectomy-free course and log-rank test to compare colectomy-free survival distributions in different subgroups. A stepwise regression model was used to look for predictive factors of long-term colectomy Results: In total, 361 patients were enrolled. Of them, 15 (4.2%) underwent early colectomy and 346 avoided colectomy: due to of IIVT response ( n = 223, 64.5%) or rescue therapy response with IFX ( n = 103, 29.7%) or CyA ( n = 20, 5.8%). Clinical characteristics of patients. During a median follow-up of 43 months (range 1–156), 67 patients (19.4%) required colectomy. The cumulative probability of a colectomy-free course was 92.7, 87, 81.9 and 79.7% after 12, 24, 36 and 60 months, respectively. Colectomy risk was similar in IIVT responders and in rescue therapy responders. During follow-up, 135 (39%) and 109 (31.5%) patients required at least one escalation of therapy and hospitalisation, respectively. At multi-variate analysis none of the covariates considered (age, gender, first or recurrent attack, disease extension, C-Reactive Protein levels, endoscopic severity, steroid/rescue therapy responsiveness, maintenance treatment) was associated to long-term colectomy risk Conclusions: The long-term colectomy risk after an acute severe attack is still relevant and do not seem to be influenced by the severity of the attack, resulting similar both in IIVT responders and in IIVT refractory patients responding to rescue therapies.
