BACKGROUND: Success achieved in two subtypes of Crohn's disease has persuaded a few investigators to experiment the monoclonal anti-tumour necrosis factor antibody infliximab in the treatment of ulcerative colitis. So far, however, the results (achieved in some 30 steroid-refractory patients included in two independent full-papers) indicate a rate of initial response of 50% and of remission of 25%. AIMS: To analyse data of an open trial conducted on consecutive steroid-refractory severely ill patients admitted to our referral Unit. PATIENTS AND METHODS: In 9 months, infliximab was given to 8 patients (4 male, 4 female aged 20-60 years) with uncontrolled ulcerative colitis of whom 6 were non-responders to parenteral steroids. All received the first infliximab dose as an intravenous infusion of 5 mg/kg. RESULTS: Of the 8, 4 (50%) did not respond to the first injection and were submitted to urgent colectomy; the other four responded clinically. Two have maintained clinical remission for 7 months, without the need for steroids; both have received daily azathioprine at 2 mg/kg, and only one has received two further infliximab injections. Of the other two, one received a second injection at week 5, despite this relapsed, and underwent elective colectomy at that time; the other relapsed at 6 months and showed a partial response to a repeat infliximab infusion. Thus, the rate of sustained response is 2/8 (25%) in this study. CONCLUSION: These results, achieved in an open uncontrolled fashion, seem to reflect those of other independent studies. In our opinion, these findings warrant an in-depth reappraisal of the indication to use infliximab as rescue treatment for refractory ulcerative colitis.
