BACKGROUND/AIMS: Results of randomized controlled trials showing efficacy of infliximab in ulcerative colitis (UC) should be confirmed in clinical practice. We aimed to evaluate the efficacy and safety of infliximab in UC patients of the Madrid area, looking for clinical predictors of response. METHODOLOGY: Multicenter retrospective survey of all UC patients treated with infliximab in the region of Madrid (Spain). RESULTS: 47 UC patients were included (45% males, mean age 44 +/- 15 yrs), mean follow up of 4.7 months (range 0.5-21), and a total number of 211 infliximab infusions. Clinical response and steroid-free remission rates were, respectively, 97/42% in the 2nd week, 93/69% in the 6th week, and 80/65% at the long-term follow up (mean 8.2 months, range 3.5-21). Colectomy rate was 10.6% (five patients). Age, gender, disease duration, indication (steroid-resistance/dependence), disease severity, C-reactive protein, concomitant thiopurinic therapy or smoking habit did not influence on efficacy. Extent of the disease was the only predictive factor (p=0.02). Only 4 cases of mild adverse events were reported. CONCLUSIONS: Infliximab is effective and safe for UC. Real life clinical practice may have better outcome than showed in randomized controlled trials. Extent of the disease was the only predictive factor for clinical response in our experience.
