Article Abstract
Objectives: The aim of the present study was to compare the efficacy and safety of 2 protocols of maintenance therapy with infliximab (IFX) and an immunomodulatory agent in pediatric patients with Crohn disease (CD): withdrawal of immunomodulators versus continuation of immunosuppressants.
Methods: The present multicenter randomized open-label trial included 99 patients with CD (ages 14.5 ± 2.6 years) who were administered IFX (5 mg/kg body weight) along with an immunomodulatory agent (azathioprine 1.5-3 mg/kg body weight per day, methotrexate 10-25 mg/week). After 10 weeks of the induction therapy, 84 responders were centrally randomized into 1 of the following groups: group I (n = 45) in which IFX and an immunomodulatory agent were continued up to week 54 and group II (n = 39) in which the immunomodulatory agent was discontinued after 26 weeks.
Results: The induction therapy was reflected by a significant decrease in Pediatric Crohn's Disease Activity Index (PCDAI) and Simplified Endoscopic Activity Score for Crohn's Disease (SES-CD) values. After the maintenance phase, the analyzed groups did not differ significantly in terms of the clinical response loss rates and final PCDAI and SES-CD scores. Furthermore, no significant intragroup differences were documented between mean PCDAI scores determined at the end of induction and maintenance phases. Intensification/modification of the treatment was required in 13 of 45 (29%) and 11 of 39 (28%) patients of groups I and II, respectively. A total of 9 serious adverse events were documented; none of the patients died during the trial.
Conclusions: Twenty-six weeks likely represent the safe duration of combined IFX/immunomodulatory therapy in our sample of pediatric patients with CD.
