Modified Crohn's Disease Exclusion Diet Maintains Remission in Pediatric Crohn's Disease; Randomized Controlled Trial.

Background & Aims: The Crohn's Disease (CD) Exclusion Diet (CDED)+Partial Enteral Nutrition (PEN) is effective for inducing remission in mild-moderate CD. We assessed whether a 2-week course of Exclusive Enteral Nutrition (EEN), followed by CDED+PEN is superior to 8 weeks of EEN in sustaining clinical remission at week 14 in mild-to-severe CD and if CDED+PEN can maintain remission to week 24.

Methods: This international, multicenter, randomized-controlled trial compared 2-weeks of EEN (Modulen®IBD) followed by 3 phases of the CDED+PEN (henceforth CDED) to 8 weeks of EEN, followed by PEN with free diet up to week 24 (henceforth EEN).

Effectiveness and Safety of Ustekinumab in Pediatric Ulcerative Colitis: A Multi-center Retrospective Study from the Pediatric IBD Porto Group of ESPGHAN.

Background And Objectives: Current data on ustekinumab therapy in children with ulcerative colitis (UC) or unclassified inflammatory bowel disease (IBDU) are limited. We aimed to evaluate the effectiveness and safety of ustekinumab in pediatric UC and IBDU.

Methods: This multicenter retrospective study included 16 centers affiliated with the IBD Interest and Porto groups of ESPGHAN.

The single-cell transcriptional landscape of innate and adaptive lymphocytes in pediatric-onset colitis.

Innate lymphoid cells (ILCs) are considered innate counterparts of adaptive T cells; however, their common and unique transcriptional signatures in pediatric inflammatory bowel disease (pIBD) are largely unknown. Here, we report a dysregulated colonic ILC composition in pIBD colitis that correlates with inflammatory activity, including accumulation of naive-like CD45RACD62L ILCs. Weighted gene co-expression network analysis (WGCNA) reveals modules of genes that are shared or unique across innate and adaptive lymphocytes.

Safety and Potential Efficacy of Escalating Dose of Ustekinumab in Pediatric Crohn Disease (the Speed-up Study): A Multicenter Study from the Pediatric IBD Porto Group of ESPGHAN.

Objectives: Escalation of the ustekinumab (UST) maintenance dosage was effective in adults with Crohn disease (CD), but no data are available for children. We evaluated the effectiveness and safety of dose escalation of UST in pediatric CD.

Methods: This was a retrospective multicenter study from 25 centers affiliated with the IBD Interest and Porto groups of ESPGHAN.

Exclusive Enteral Nutrition: Clinical Effects and Changes in Mucosal Cytokine Profile in Pediatric New Inflammatory Bowel Disease.

Exclusive Enteral Nutrition (EEN) is the first-line treatment in children with Crohn's disease (CD) for induction of remission. However, the mode of action remains conjectural. The aim of this study was to investigate whether the effect of EEN is paralleled by changes in the mucosal cytokine profiles (MCP).

Mucosal Cytokine Profiles After Induction Therapy With Granulocyte/Monocyte Apheresis in New-onset Inflammatory Colitis.

Granulocyte/monocyte apheresis (GMA) selectively removes circulating granulocytes and monocytes; important producers of proinflammatory cytokines. Seven children with new-onset inflammatory bowel disease (IBD) colitis were treated with GMA together with mesalazine, and had significant decreases in Pediatric UC Activity Index (P = 0.018) and Mayo endoscopic score (P = 0.

Granulocyte and Monocyte Apheresis for Induction of Remission in Children With New-Onset Inflammatory Bowel Colitis.

Objective: The aim of the study was to analyze the effect of granulocyte and monocyte apheresis (GMA) with mesalazine for induction of remission in pediatric patients with newly onset chronic inflammatory bowel disease (IBD) colitis.

Methods: Thirteen pediatric patients with newly onset extensive IBD colitis were investigated per the ECCO/ESPGHAN IBD protocol. Of these 13, 12 received 10 treatments with Adacolumn (ADA) during a median of 6.

Serum-Infliximab Trough Levels in 45 Children with Inflammatory Bowel Disease on Maintenance Treatment.

The role of trough serum infliximab (s-IFX) and antibodies toward IFX (ATI) during maintenance treatment remains unclear in children. The aim of the present study was to investigate trough s-IFX and ATI to identify any correlation with inflammatory activity and clinical response in a pediatric inflammatory bowel disease (IBD) cohort. We investigated the s-IFX trough levels in pediatric IBD patients ( = 45) on maintenance IFX treatment.
