Crohn disease

Multiple studies have indicated a potential correlation between immune-mediated inflammatory diseases (IMIDs) and Frozen shoulder (FS). To explore the genetic causal relationship between IMIDs and FS using 2-sample Mendelian randomization (MR) analysis. Genome-wide association study (GWAS) summary data for FS were obtained from Green's study, while data for 10 IMIDs were sourced from the FinnGen Consortium. The MR analysis was performed using inverse variance weighting, MR Egger, and weighted median methods...

BACKGROUND AND AIMS: Despite advances in the medical treatment of Crohn's disease (CD), many patients will still need bowel resections and face the subsequent risk of recurrence and re-resection. We describe contemporary re-resection rates and identify disease-modifying factors and risk factors for re-resection. METHODS: We conducted a retrospective, population-based, individual patient data cohort study covering 47.4% of the Danish population, including all CD patients who underwent a primary resection between 2010 and 2020...

An idiopathic condition known as inflammatory bowel disease (IBD) is characterized by a dysregulated immune response to the intestinal flora of the host. It falls into one of two primary categories: ulcerative colitis or Crohn's disease. A wide range of disorders, both clinically and genetically, can cause IBD. The purpose of this thorough analysis is to determine the significance and reliability of the correlation between perinuclear antineutrophil cytoplasmic antibodies (p-ANCA) and IBD, as well as the implications of this correlation for the diagnosis and treatment of IBD...

A 46-year-old woman with fistulizing Crohn's disease in clinical remission in the setting of long-term adalimumab therapy presented to hospital and was ultimately diagnosed with anti- N -methyl-D (NMDA) receptor antibody-mediated autoimmune encephalitis (NMDAr-AE). Inflammatory central nervous system and antibody-mediated adverse effects have been found to be associated with anti-tumor necrosis factor agents, with 5 previous case reports noting cases of NMDAr-AE in patients on these medications. The current article reports this case, which is unique for the length of adalimumab therapy before this presentation, as well as a summary of literature regarding anti-tumor necrosis factors and NMDAr-AE...

BACKGROUND: Several studies suggest that women with Crohn disease (CD) have reduced fertility due to decreased ovarian reserve, among other causes. On the other hand, male CD patients could have difficulties conceiving. The present study aimed to test the effect of CD on both male and female fertility potential, Sertoli cell function and ovarian reserve, assessed by inhibin-B (IB) plus IB:FSH ratio (IFR) and antiMüllerian hormone (AMH), respectively. Sexual dysfunction (SD) was studied as secondary endpoint...

Inflammatory bowel disease (IBD) is rapidly emerging in the Asia Pacific region. However, there are many challenges in the diagnosis and management of this condition. The Asian Pacific Association of Gastroenterology (APAGE) Working Group on IBD conducted a round table meeting to identify 10 common mistakes in the management of IBD in Asia. To summarize, many physicians still over rely on a definitive histological diagnosis before starting treatment and do not fully establish disease extent such as perianal and proximal gastrointestinal involvement in Crohn's disease (CD) or extent of involvement in ulcerative colitis (UC)...

BACKGROUND: MRI diffusion-weighted imaging (DWI) is commonly used in MR enterography protocols for assessment of intestinal inflammation in patients with Crohn's disease. The intravoxel incoherent motion (IVIM) approach to DWI has been proposed as a more objective approach, providing quantitative parameters that reflect water diffusivity (D), blood flow (D*), and perfusion fraction (f). PURPOSE: We aimed to determine if DWI-IVIM metrics from the terminal ileum in patients with newly diagnosed Crohn's disease differ from healthy participants and change in response to biologic medical therapy...

BACKGROUND AND AIMS: Biologic therapies may effectively treat Crohn's disease (CD), and pediatric patients who discontinue multiple biologics risk exhausting treatment options. The frequency and context of biologic discontinuation has not been well characterized. We aimed to determine patterns of biologic use, discontinuation, and evaluation in pediatric patients with CD. METHODS: Pediatric patients with CD at seven US centers (2010-2020) were identified. Prospective ImproveCareNow registry data were supplemented with medical record abstraction...

OBJECTIVE: Normal quality of life is an ultimate target in the therapeutic approach to Inflammatory Bowel Diseases (IBD), encompassing Crohn's disease (CD) and ulcerative colitis (UC) in the context of which regular physical activity (PA) is often a chimeric parameter that is not standardised in terms of quality/quantity. The study aimed to profile a sample of IBD patients about the relationship between PA-partner status and social network support. PATIENTS AND METHODS: A post-hoc analysis of the "BE-FIT-IBD" study was set up by stratifying the data of PA with that of partner status and the support that the patient's social network (i...

Group 3 innate lymphoid cells (ILC3s) are key players in intestinal homeostasis. Endoplasmic reticulum (ER) stress is linked to inflammatory bowel disease (IBD). Herein, we used cell culture, mouse models, and human specimens to examine if ER stress in ILC3s impacts IBD pathophysiology. We show that mouse intestinal ILC3s exhibited a 24h-rhythmic expression pattern of the master ER stress response regulator, IRE1α/XBP1. Proinflammatory cytokine IL-23 selectively stimulated IRE1α/XBP1 in mouse ILC3s through mitochondrial reactive oxygen species (mtROS)...

BACKGROUND AND AIMS: Pan-enteric capsule endoscopy (PillCam Crohn's capsule [PCC]) is a useful tool in diagnosing and monitoring Crohn's disease (CD). Eliakim score [ES] reliability and strong correlation to Lewis score (LS) and inflammatory biomarkers have been previously demonstrated using PCC in quiescent CD. We aimed to examine ES performance in active CD and its responsiveness to clinical/biochemical change over time. METHODS: Patients with CD who have started biologics were included, and were prospectively followed with clinical visits, biomarkers, and PCC at baseline, after 14 and 52 weeks...

BACKGROUND & AIMS: Inflammatory bowel disease (IBD) is commonly associated with extraintestinal complications, including autoimmune liver disease. The co-occurrence of IBD and primary biliary cholangitis (PBC) has been increasingly observed, but the underlying relationship between these conditions remains unclear. METHODS: Using summary statistics from genome-wide association studies (GWAS), we investigated the causal effects between PBC and IBD, including Crohn's disease (CD) and ulcerative colitis (UC)...

BACKGROUND: Since 2009, inflammatory bowel disease (IBD) specialists have utilized "IBD LIVE," a weekly live video conference with a global audience, to discuss the multidisciplinary management of their most challenging cases. While most cases presented were confirmed IBD, a substantial number were diseases that mimic IBD. We have categorized all IBD LIVE cases and identified "IBD-mimics" with consequent clinical management implications. METHODS: Cases have been recorded/archived since May 2018; we reviewed all 371 cases from May 2018-February 2023...

BACKGROUND: Eosinophilic esophagitis (EoE) and inflammatory bowel diseases (IBDs), including Crohn's disease (CD) and ulcerative colitis (UC), are immune-mediated gastrointestinal diseases with overlapped pathogenesis and are sometimes concurrently diagnosed, but their causal relationship remains unclear. We investigated the causal relationship between EoE and IBD and its subtypes via a two-sample bidirectional Mendelian randomization (MR) approach. METHODS: MR analyses were performed using summary data of a genome-wide association study (GWAS) on individuals of European ancestry...

BACKGROUND AND AIMS: Several fecal microbial transplantation (FMT) approaches for ulcerative colitis (UC) have been investigated with conflicting results. We have recently published the clinical outcomes from the CRAFT-UC Trial using FMT with the UC Exclusion Diet (UCED), compared with FMT alone. Here we aimed to compare the two FMT strategies in terms of microbial profile and function. METHODS: Subjects recruited to the CRAFT-UC study with available pre- and post-intervention fecal samples were included...

INTRODUCTION: Ulcerative colitis (UC) and Crohn's disease (CD) are diseases that cause a significant impact on patients' quality of life.The aim of this study is to assess the impact of inflammatory bowel disease (IBD) on health-related quality of life (HRQoL). MATERIAL AND METHODS: Observational, descriptive, cross-sectional study, carried out at Torrecárdenas Hospital (Almería). Patients over 14 years of age diagnosed with CD or UC were included.For the assessment of HRQoL, the reduced 9-item IBDQ-9 questionnaire was used...

BACKGROUND: Oncostatin-M (OSM) is associated with antitumor necrosis factor (anti-TNF)-α resistance in inflammatory bowel disease (IBD) and fibrosis in inflammatory diseases. We studied the expression of OSM and its receptors (OSMR, gp130) on intestinal subepithelial myofibroblasts (SEMFs) and the effect of OSM stimulation on SEMFs. METHODS: The mRNA and protein expression of OSM, OSMR, gp130, and several fibrotic and chemotactic factors were studied in mucosal biopsies and isolated human intestinal SEMFs of patients with IBD and healthy controls (HCs) and in a model of human intestinal organoids (HIOs)...

BACKGROUND: We aimed to determine the correlation between tissue and plasma infliximab concentrations in an outpatient ulcerative colitis (UC) cohort based on histologic disease activity in addition to their relationship with long-term clinical outcomes. We assessed intraparticipant variability in infliximab concentrations between adjacent intestinal samples and the correlation between disease activity and tumor necrosis factor-α (TNF-α). METHODS: A prospective cohort study was conducted in participants with UC receiving infliximab...
