BACKGROUND AND AIMS: The utility of postoperative medical prophylaxis (POMP) and the treatment of mild endoscopic recurrence remain controversial. METHODS: This study is a retrospective review of patients undergoing a primary ileocolic resection for CD at a single academic center. Endoscopic recurrence (ER) was defined using the Rutgeerts score (RS), and clinical recurrence (CR) was defined as symptoms of CD with endoscopic or radiologic evidence of neo-terminal ileal disease...

OBJECTIVE: In recent years, S-nitrosoglutathione has been proposed for the treatment of Crohn's disease to prevent mucosal barrier failure. In this paper, we report the formulation of spray dried microparticles of glutathione and S-nitrosoglutathione based on Eudragit(®) FS 30D polymer (i.e. colon-specific delivery system). MATERIAL AND METHODS: The influence of several spray-drying parameters (inlet temperature 80-150°C, solvent flow 5-10mL/min) was studied. The parameters that yielded the best formulations (inlet temperature 120°C, outlet temperature 47°C, solvent flow 5mL/min and air flow 100%) were selected for further studies...

PURPOSE: Patients with inflammatory bowel disease (IBD) often experience severe impairment in different life domains. Psychological factors, such as illness perceptions and coping, may play a role in the adjustment to IBD as indicated by mental and physical health, activity, and work impairment. The present study aimed at examining the assumption of the Common Sense Model (CSM) that coping mediates the relationship between illness perceptions and adjustment in patients with IBD. METHOD: In a cross-sectional design, 211 IBD patients (73 % Crohn's disease, 40 % male, mean age 42...

BACKGROUND: As variation in care has previously been linked to quality, we aimed to describe variations in inflammatory bowel diseases care by gastroenterology (GI) practice setting. METHODS: We performed a cross-sectional study within the Crohn's and Colitis Foundation of America Partners and used bivariate analyses to compare patient characteristics by GI practice setting (GI-academic [GIA], GI-private, or GI-other). Regression models were used to describe the effects of provider type on steroid use, disease activity, and the quality of life...

OBJECTIVE: The clinical presentation and course of Crohn's disease (CD) is highly variable. We sought to better understand the cellular and molecular mechanisms that guide this heterogeneity, and characterise the cellular processes associated with disease phenotypes. DESIGN: We examined both gene expression and gene regulation (chromatin accessibility) in non-inflamed colon tissue from a cohort of adult patients with CD and control patients. To support the generality of our findings, we analysed previously published expression data from a large cohort of treatment-naïve paediatric CD and control ileum...

We aimed to examine correlation of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) with diagnosis of inflammatory bowel disease (IBD) and with clinical, endoscopic, histological and radiographic disease activity during follow-up. We reviewed charts of 135 children with IBD and correlated their ESR and CRP values with disease activity in various encounters over 5 years. Normal ESR and CRP values were observed in up to 28% of children with Crohn's disease and 42% of children with ulcerative colitis at diagnosis respectively...

TL1A contributes to the pathogenesis of several chronic inflammatory diseases, including those of the bowel by enhancing TH1, TH17, and TH2 responses. TL1A mediates a strong costimulation of these TH subsets, particularly of mucosal CCR9(+) T cells. However, the signaling pathways that TL1A induces in different TH subsets are incompletely understood. We investigated the function of TL1A on human TH17 cells. TL1A, together with TGF-β, IL-6, and IL-23, enhanced the secretion of IL-17 and IFN-γ from human CD4(+) memory T cells...

Pathogenesis of Crohn's disease (CD) involves immune and microbial dysregulation, induced by environmental factors in genetically susceptible individuals. There are believed to be multiple subtypes of CD, which contributes to its observed clinical heterogeneity. This concept has been reinforced by recognition of the complexity of the genetic, microbial, immune, and environmental factors that affect risk for CD. Paneth cells mediate immunity in and maintain the small intestinal epithelium; defects in activities of these cells have been observed in high proportions of patients with CD, and associated with more aggressive CD phenotype...

BACKGROUND: Visceral hypersensitivity (VH) is a common condition in many gastrointestinal disorders such as inflammatory bowel diseases (IBDs) in human and animals. Most studies often induce Crohn's disease/colitis to investigate VH in small experimental animals. Although farm animals commonly suffer from IBDs, their VH has not been investigated so far. Because goats can suffer from Johne's disease, a naturally occurring Crohn's-like disease, they may be suitable to be used for studying the mechanism underlying VH in common intestinal disorders of large animals...

After the expiry date of the patent protection for Infliximab in 2013, the biosimilar CT‑P13 was approved for indications in Crohn's disease and ulcerative colitis in adults as well as in children. The approval has been based on two randomized clinical studies indicating equivalence for the biosimilar with regard to pharmacokinetics, efficacy, as well as side-effects. The clinical experience since, in addition to multiple non-randomized studies, indicate a comparable efficacy and immunogenicity of the Infliximab biosimilar CT-P13 in inflammatory bowel disease...

Inflammatory bowel disease (IBD) includes a spectrum of diseases from ulcerative colitis (UC) to Crohn's disease (CD). Many studies have addressed the changes in the microbiota of individuals affected by UC and CD. A decrease in biodiversity and depletion of the phyla Bacteroidetes and Firmicutes has been reported, among others. Changes in microbial composition also result in changes in the metabolites generated in the gut from microbial activity that may involve the amount of butyrate and other metabolites such as H2 S being produced...

The human intestinal tract harbors large bacterial community consisting of commensal, symbiotic, and pathogenic strains, which are constantly interacting with the intestinal immune system. This interaction elicits a non-pathological basal level of immune responses and contributes to shaping both the intestinal immune system and bacterial community. Recent studies on human microbiota are revealing the critical role of intestinal bacterial community in the pathogenesis of both systemic and intestinal diseases, including Crohn's disease (CD)...

BACKGROUND: Paneth cell dysfunction has been implicated in a subset of Crohn's disease (CD) patients. We previously stratified clinical outcomes of CD patients by using Paneth cell phenotypes, which we defined by the intracellular distribution of antimicrobial proteins. Animal studies suggest that Paneth cells shape the intestinal microbiome. However, it is unclear whether Paneth cell phenotypes alter the microbiome complexity in CD subjects. Therefore, we analyzed the correlation of Paneth cell phenotypes with mucosal microbiome composition and ileal RNA expression in pediatric CD and noninflammatory bowel disease (non-IBD) patients...

BACKGROUND & AIMS: The inflammatory bowel diseases (IBD) ulcerative colitis (UC) and Crohn's disease (CD) cause significant morbidity and are increasing in prevalence among all populations, including African Americans. More than 200 susceptibility loci have been identified in populations of predominantly European ancestry, but few loci have been associated with IBD in other ethnicities. METHODS: We performed 2 high-density, genome-wide scans comprising 2345 cases of African Americans with IBD (1646 with CD, 583 with UC, and 116 inflammatory bowel disease unclassified [IBD-U]) and 5002 individuals without IBD (controls, identified from the Health Retirement Study and Kaiser Permanente database)...

Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases (IBD) characterized by recurrent episodes of mucosal inflammation. This chronic mucosal inflammation has several potential consequences, one of which is the occurrence of colitis associated colorectal cancer (CRC). Over the past decade our understanding of the epidemiology, pathophysiology, and overall approach to diagnosing and managing colitis associated CRC, has grown considerably. In the current review article, we outline these advancements and highlight areas in need of further research...

Advances in flow and mass cytometry are enabling ultra-high resolution immune profiling in mice and humans on an unprecedented scale. However, the resulting high-content datasets challenge traditional views of cytometry data, which are both limited in scope and biased by pre-existing hypotheses. Computational solutions are now emerging (e.g., Citrus, AutoGate, SPADE) that automate cell gating or enable visualization of relative subset abundance within healthy versus diseased mice or humans. Yet these tools require significant computational fluency and fail to show quantitative relationships between discrete immune phenotypes and continuous disease variables...

Intestinal subepithelial myofibroblasts (SEMFs) exert a profibrotic role in Crohn's disease (CD). Tumor necrosis factor-like cytokine 1A (TL1A) and its receptors, death-domain receptor 3 (DR3) and decoy receptor 3 (DcR3), are mucosal factors with significant involvement in experimental inflammation and CD. We aimed to determine the regulation of expression of this system of proteins in SEMFs and intestinal epithelial cells. The relative amount of mRNA transcripts for TL1A, DR3, and DcR3 was measured by real-time reverse transcription polymerase chain reaction in cultured primary SEMFs, colonic myofibroblast cell line 18CO, and epithelial cell line HT29...

BACKGROUND: The potential need for an ostomy is a main concern for patients with inflammatory bowel disease. We performed this study to evaluate the impact of a long-term ostomy (≥6 mo duration) on the functional status and specific patient-reported outcomes in a population of patients with Crohn's disease (CD). METHODS: We performed a cross-sectional analysis within the Crohn's and Colitis Foundation of America Partners cohort. Bivariate analyses and logistic regression models were used to investigate associations between ostomy and various demographic, disease factors, and patient-reported outcomes for health-related quality of life...
