Infliximab (IFX) has been proven effectivein RCTs both for induction of remission and maintenance in moderate-to-severe ulcerative colitis (UC). The aim of this study is to provide data on IFX efficacy in UC in everyday clinical practice.


Eleven referral and non-referral centers from Southern Italy participated in the study. All patients with UC who received at least one infusion of IFX from January 2008 to June 2012 were recruited. Clinico-demographic characteristics, IFX indications, concomitant therapy anddisease activity were registered. Outcomes evaluated were clinical and endoscopic responses at week 14 and 52, steroid-free remission, colectomy rate.


319 patients (60.2% males, mean age 35.4) were enrolled. Extent of disease was pancolitis in 67.1%, left-sided colitis in 24.8%, proctosigmoiditis in 8.2%. Median duration of disease was 51 months. Median follow-up was 23 months. Indication to IFX were steroid dependence in 75.3%, steroid-resistance in 16.9%, extra-intestinal complications in 2.2%, rescue therapy for severe refractory UC in 5.6%. Patients received a median of 10 (range 5–16) infusions. Mayo score was 8.3 at enrolment, 4.3 at 14 weeks and 3.2 at 52 weeks (p < 0.001). Steroids were used in 93.5% at baseline, 44.4% at week 14 and 26% at week 52. Mucosal healing was obtained in 77.3%. Colectomy rate was 8.3%. Median time to colectomy was 5 months. Results were compared in steroid dependent versus steroid-resistantpatients, IFX monotherapyversus combo and long-lasting versus recent disease. Colectomy rate was significantly higher in steroid-resistant (p = 0.0003) patients; steroid-free remission was less common in long-lasting disease.


Infliximab is effective in inducing short and long-term clinical response, mucosal healing, steroids sparing and in reducing colectomy rate in moderate-to-severe UC. Steroid-dependent disease is the most frequent indication in the “real-life” with favourable outcomes and a lower rate of colectomy.
