Objectives: In the era where new biologicals are entering the market, the place of immunomodulators in the treatment of pediatric inflammatory bowel disease (IBD) needs to be reassessed. Methods: All children with Crohn's disease (CD) or ulcerative colitis (UC) followed at our center over the last 10 years were reviewed. Children who received conventional therapy (including 5-aminosalicylates, steroids, thiopurines and methotrexate) since diagnosis were included. Primary outcome was steroid-free clinical remission without need for rescue therapy (biologics or surgery) at 6 and 12 months after diagnosis and at last follow-up. Cox proportional hazard modelling was performed to determine variables at diagnosis associated with outcomes. Results: In total, 176 IBD patients (121 CD, 55 UC) were identified with a median follow-up of 4.6 [2.0-8.1] years. Remission rates were 79.6% at month 6, but decreased to 60.2% at month 12, and 31.8% at last follow-up. Higher CRP [1.006 (1.001-1.011)], lower albumin [1.050 (1.012-1.086)] and growth impairment [1.214 (1.014-1.373)] in CD patients and higher PUCAI score [1.038 (1.006-1.072)] and low iron [1.023 (1.003-1.043)] in UC patients were associated with treatment failure (all p < 0.05). Conclusion: Only 32% pediatric IBD patients will remain free of biologics or surgery 5-years after diagnosis. Especially children with a high disease burden at diagnosis were more likely to fail conventional therapy. (C) 2019 Published by Elsevier Ltd on behalf of Editrice Gastroenterologica Italiana S.r.l.
