To assess the clinical efficacy and the impact of infliximab (IFX) induction therapy on mucosal healing in Polish children with Crohn's disease (CD).


A total of 66 children (29 boys and 37 girls) aged 14.06 ± 3.59 years with CD diagnosed at the mean age of 8.4 ± 7.3 years were included in the study. Patients received IFX (5 mg/kg) in three repeated infusions at 0, 2, and 6 weeks. The clinical activity of the disease was assessed using the Pediatric Crohn's Disease Activity Index (PCDAI) and the endoscopic activity was scored using the Simple Endoscopic Score for Crohn's disease at baseline and at week 10.


Twenty-two (33%) of the studied patients reached clinical remission (PCDAI ≤ 10), 26 (39%) showed a clinical response (PCDAI between 15 and 30), and 18 (28%) did not respond to the therapy. When comparing data at baseline and at week 10, significant decreases were observed in the median PCDAI, C-reactive protein, and platelet count. In addition, a significant increase in BMI was noted. A significant decrease in the Simple Endoscopic Score for CD was observed between the initial and the control colonoscopies. Fifteen out of 66 patients (22.7%) had score 0 in the control endoscopy at week 10. No adverse events leading to therapy termination were observed.


Biological therapy with IFX enables mucosal healing in pediatric patients with CD. Induction therapy with infliximab was found to be clinically effective in 72% of Polish pediatric patients with CD and induced a remission in 33% of them. Induction therapy with infliximab helps to increase BMI.
