title: [Infliximab therapy for inflammatory bowel disease: seven years on].
abstract: BACKGROUND
  The aim of this study was to describe the clinical experience of our center of the use of infliximab in pediatric patients with inflammatory bowel disease.
  
  
  METHODS
  We retrospectively reviewed all infliximab infusions administered in the Pediatric Gastroenterology Unit from October of 1999 to October of 2006. Fourteen patients (nine with Crohn's disease, three with ulcerative colitis, and two with indeterminate colitis) with a mean age of 9.6 years at diagnosis were treated with infliximab. Seventy-seven infusions were administered.
  
  
  RESULTS
  Efficacy was analyzed according to inflammatory bowel disease. Crohn's disease: in severe cases (PCDAI > 30), clinical remission (PCDAI < 10) was obtained in 80 % of the patients at week 10, decreasing to 60 % at week 54. Corticosteroid therapy could be reduced in 89 % of the patients and was discontinued in 55.5 %. Ulcerative colitis: clinical remission (modified Truelove-Witts index < 10) was initially obtained in 100 % of the patients but only 33 % were still in clinical remission at the end of the study. In the two corticosteroid-dependent patients, corticosteroid therapy could be reduced and even discontinued in one (50 %). Indeterminate colitis: neither of the two patients achieved clinical remission. The most frequent adverse effects observed were acute infusional reactions (42.8 % of the patients and 10.3 % of infusions), one of which was severe, and infections (28.6 % of patients), one of which (ileal abscess) required surgery.
  
  
  CONCLUSIONS
  The efficacy of infliximab seems to differ considerably in the distinct types of inflammatory bowel disease and is practically null in indeterminate colitis. Randomized controlled studies in children are required to assess the exact efficacy of infliximab in our patients.
