Background: Infliximab and adalimumab are the only biologics thus far approved for paediatric patients with inflammatory bowel disease (IBD), so other biologics, such as vedolizumab, are prescribed off-label. Despite its frequent use, prospective data for vedolizumab treatment in children are available only for short-term induction outcomes. We aimed to evaluate the long-term efficacy and safety of maintenance therapy with vedolizumab in paediatric patients with IBD.

Objectives: The PRASCO trial reported the short-term superiority of an antibiotic cocktail plus intravenous corticosteroids (IVCS) over IVCS alone in children with acute severe colitis (ASC). Here, we report the extension of the PRASCO trial and the long-term outcomes of the antibiotic cocktail in ASC.

Methods: This prospective follow-up of the PRASCO trial documented disease outcomes and treatments annually through 5 years.

Objective: The utilization of biologic drugs in children with inflammatory bowel disease (IBD) surged following the publications of positive results in randomized controlled trials and real-world studies. We aimed to explore the extent of publication bias associated with these findings.

Methods: Two reviewers assessed all abstracts evaluating the efficacy or safety of biologics presented at the annual European Society for Pediatric Gastroenterology Hepatology and Nutrition and North American Society for Pediatric Gastroenterology conferences from 2015 to 2019.

Background: To advance personalized medicine in pediatric Crohn's disease (CD), we aimed to explore the utility of serological biomarkers in predicting response to anti-tumor necrosis factor (TNF).

Methods: Children with CD were enrolled at initiation of anti-TNF and followed prospectively at 4 and 12 months thereafter, as well as at last follow-up. At baseline, 10 serological markers of the "PROMETHEUS® IBD sgi Diagnostic test" were measured, including pANCA, ASCA IgG and IgA, anti-CBir1, anti-OmpC, anti-A4-Fla2, anti-Fla-X, SAA, ICAM-1 and VCAM-1.

Background: Data on predictors of complicated ulcerative colitis (UC) course from unselected populations cohorts are scarce. We aimed to utilize a nationwide cohort to explore predictors at diagnosis of disease course in children and adults with UC.

Methods: Data of patients diagnosed with UC since 2005 were retrieved from the nationwide epi-IIRN cohort.
