A 35-year old woman with ileocolonic, perianal and vulval Crohn's disease was treated with subcutaneous ustekinuamb (USK) throughout pregnancy. Dose intervals were shortened from 6-weekly to 4-weekly to maintain clinical remission. The last dose of USK was administered at 33 weeks gestation and a healthy baby boy was delivered by caesarean section at 37 weeks. Maternal trough USK levels remained stable during pregnancy. Cord blood USK levels were nearly two-fold higher than contemporaneous maternal serum levels...

Background and Aims: Ulcerative colitis (UC) is a chronic inflammatory disease that effects the gastrointestinal tract and is considered one of the most prominent and common forms of inflammatory bowel disease (IBD). This study aimed to define and describe the entire transcriptomic landscape in a well-stratified, treatment-naïve UC patient population compared to control patients by using next-generation technology, RNA-Seq. Methods: Mucosal biopsies from treatment-naïve UC patients (n=14), and healthy controls (n=16) underwent RNA-Seq...

Background and Aims: Several studies have suggested significant associations between environmental factors and the risk of developing inflammatory bowel disease (IBD). However, data supporting the role of antibiotics are conflicting. The aim of this study was to evaluate the association between antibiotic use and new-onset IBD. Methods: We conducted a population-based case-control study using the Rochester Epidemiology Project of Olmsted County, Minnesota. We identified 736 county residents diagnosed with IBD between 1980 and 2010 who were matched to 1472 controls, based on age, sex and date of IBD diagnosis...

Background and Aims: The incidence of childhood-onset (<18 years) inflammatory bowel disease is increasing worldwide, and some studies suggest that it represents a more severe disease phenotype. Few nationwide, population-based studies have evaluated the surgical burden in patients with childhood-onset IBD, and whether the improved medical treatment has influenced the need for gastrointestinal surgery. The aim was to examine whether the surgical treatment at any age of patients with childhood-onset IBD has changed over time...

Background: Genital granulomatosis (GG) is a metastatic form of Crohn's Disease (CD), characterized by granulomatous inflammation of the genital skin without contact to the gastrointestinal tract. Little is known about GG as most publications are case reports or small series, and only sporadic in male cases. Methods and Aims: Cases of GG were retrospectively collected through the Collaborative Network For Exceptionally Rare case reports project of the European Crohn´s and Colitis Organization...

Background: Endoplasmic reticulum stress was shown to be pivotal in the pathogenesis of inflammatory bowel disease. Despite progress in IBD drug development, not more than one third of patients achieve steroid-free remission and mucosal healing with current therapies. Furthermore, patient stratification tools for therapy selection are lacking. We aimed to identify and quantify epithelial ER stress in a patient-specific manner in an attempt towards personalized therapy. Methods: A biopsy-derived intestinal epithelial cell culture system was developed and characterized...

Background and Aims: Crohn's disease-related complications account for a substantial proportion of inflammatory bowel disease-associated healthcare expenditure. Identifying patients at risk for complications may allow for targeted use of early therapeutic interventions to off-set this natural course. We aimed to develop risk prediction models for Crohn's disease-related surgery and complications. Methods: Using data from the Randomized Evaluation of an Algorithm for Crohn's Disease cluster-randomized clinical Trial (REACT), which involved 1898 patients from 40 community practices...

Background and aims: Triggering receptor expressed on myeloid cells-1 [TREM-1] is known to amplify inflammation in several diseases. Autophagy and endoplasmic reticulum [ER] stress, which activates the unfolded protein response [UPR] are closely linked and defects in these pathways contribute to the pathogenesis of inflammatory bowel disease [IBD]. Both autophagy and UPR are deeply involved in host-microbiota interactions for the clearance of intracellular pathogens thus contributing to dysbiosis...

Background & Aims: Progressive multifocal leukoencephalopathy, a brain infection associated with anti-integrin drugs that inhibit lymphocyte translocation from bloodstream to tissue, can be fatal. Decreased central-nervous-system immune surveillance leading to this infection has been reported in patients with multiple sclerosis or Crohn's disease treated with anti-integrin antibody natalizumab. PF-00547659 is an investigational human monoclonal antibody for inflammatory bowel disease targeted against α4β7-mucosal addressin cell-adhesion molecule-1 (the integrin ligand selectively expressed in the gut)...

Background: Patients with inflammatory bowel disease (IBD) often suffer from rheumatic manifestations, including inflammatory back disorders. The prevalence of these disorders late in the course of IBD is poorly investigated. The aim of this study was to estimate the prevalence of inflammatory back disorders in patients with IBD 20 years after diagnosis and to investigate possible associations with IBD severity, HLA-B27 and the NOD2 genotype. Methods: A population-based cohort (the IBSEN study) was followed prospectively for 20 years...

Background and Aims: Novel noninvasive biomarkers with high diagnostic accuracy are required to assess mucosal healing, which is associated with sustained clinical remission, in inflammatory bowel disease. This study aimed to explore sepsis markers as potential biomarkers for mucosal healing. Methods: Patients with ulcerative colitis (UC) or Crohn's disease (CD) who underwent blood tests for C-reactive protein (CRP), serum procalcitonin (PCT) and soluble interleukin-2 receptor (sIL-2R), and plasma soluble CD14 subtype (sCD14-ST), within two weeks of endoscopy were retrospectively recruited and we assessed the relationship between marker levels and clinical features...

Azathioprine is commonly used in Crohn's Diseases. It has been administered to many pregnant women over many years without significant side effects. However, pancytopenia and Severe Combined Immune Deficiency-like disease have been reported in infants whose mothers received azathioprine throughout pregnancy. Moreover, myelotoxicity has been described in patients treated with azathioprine and having a low or absent thiopurine S-methyl transferase (TPMT) activity.Here, we describe the case of a new-born girl found highly lymphopenic (<300 CD3+ T cells) after a positive new-born screening for Severe Combined Immuno Deficiency...

Background: Both fecal calprotectin (Fcal) and the fecal immunochemical test (FIT) are useful to predict clinical relapse of ulcerative colitis (UC). However, the difference between Fcal and FIT in the ability to predict relapse has scarcely been reported. Whether the combined use of these two fecal markers increases the predictability is also unknown. Methods: UC patients in clinical remission who underwent colonoscopy were enrolled prospectively, and the Fcal and FIT values were examined at enrollment...

Introduction: There are no data on the transfer of vedolizumab in breast milk of nursing mothers. We aimed to assess the presence of vedolizumab in breast milk of nursing inflammatory bowel disease (IBD) patients. Methods: This was a prospective observational study of vedolizumab-treated breast-feeding patients with IBD. Serum and breast milk samples were obtained at pre-defined time-points. The in-house developed ELISA assay for measuring vedolizumab in blood was adapted and validated for measurement of drug in breast milk...

The therapeutic landscape for inflammatory bowel disease (IBD) is rapidly evolving. Two new biologic drugs, vedolizumab and ustekinumab, have recently entered the marketplace, the first biosimilars have been introduced, and several other agents are at an advanced stage of clinical development. In parallel, therapeutic goals have shifted from symptom control towards mucosal healing and prevention of bowel damage. In the coming years, gastroenterologists will be faced with unprecedented choices when selecting the best treatment for their patients with IBD...
