Campylobacter concisus is an oral bacterium that is associated with inflammatory bowel disease. C. concisus has two major genomospecies, which appear to have different enteric pathogenic potential. Currently, no studies have compared the genomes of C. concisus strains from different genomospecies. In this study, a comparative genome analysis of 36 C. concisus strains was conducted including 27 C. concisus strains sequenced in this study and nine publically available C. concisus genomes. The C. concisus core-genome was defined and genomospecies-specific genes were identified...

Regulatory T (Treg) cells expressing the transcription factor FOXP3 play a pivotal role in maintaining immunologic self-tolerance. We and others have previously shown that EZH2 is recruited to the FOXP3 promoter and its targets in Treg cells. To further address the role for EZH2 in Treg cellular function, we have now generated mice that lack EZH2 specifically in Treg cells (EZH2ΔFOXP3+). We find that EZH2 deficiency in FOXP3+ T cells results in lethal multi-organ autoimmunity. We further demonstrate that EZH2ΔFOXP3+ T cells lack a regulatory phenotype in vitro and secrete pro-inflammatory cytokines...

Currently, several non-invasive modalities, including MRI and PET, are being investigated to identify early intestinal inflammation, longitudinally monitor disease status, or detect dysplastic changes in patients with inflammatory bowel disease (IBD). Here, we assess the applicability and utility of multispectral optoacoustic tomography (MSOT) in evaluating the presence and severity of colitis. Mice with bacterial colitis demonstrated a temporally associated increase in mesenteric and colonic vascularity with an increase in mean signal intensity of oxygenated hemoglobin (p=0...

The most common small bowel inflammatory disorders include Crohn disease, nonsteroidal antiinflammatory drug (NSAID) enteropathy, and celiac disease. Capsule endoscopy, computed tomography enterography, and magnetic resonance enterography have a complementary role in the diagnosis of Crohn disease and evaluation of patients with established Crohn disease. The higher risk of capsule retention with known Crohn disease and NSAID enteropathy can be minimized by cross-sectional imaging or the patency capsule. The main role of deep enteroscopy is tissue diagnosis, endoscopic management of small bowel lesions and strictures, and retrieval of retained capsules...

BACKGROUND AND AIMS: The chemopreventive effect of 5-aminosalicylic acid (5-ASA) in patients with inflammatory bowel disease (IBD) has been widely studied; however, the results remain conflicting. The aim of this study was to systematically review the literature and update evidence concerning effects of 5-ASA on the risk of colorectal cancer (CRC) and dysplasia (Dys) in patients with ulcerative colitis (UC) or Crohn's disease (CD). RESULTS: 5-ASA showed a chemopreventive effect against CRC/Dys in IBD patients (OR = 0...

The relationship between Microscopic Colitis and Inflammatory Bowel Disease is unclear. However, when both are diagnosed they seem to be part of a broader spectrum of the same disease, more than just a coincidence. We report a 55 years old woman with Ulcerative Colitis limited to the rectum with complete clinical and endoscopic response to standard treatment and adequate surveillance for 13 years, who abandoned treatment and control. After eight years, she consulted for mild-to-moderate non-bloody diarrhea lasting several months...

BACKGROUND: Musculoskeletal manifestations (MSM) of inflammatory bowel diseases (IBDs) are usually the most frequent extraintestinal manifestations. However, they are not paid enough attention during regular office visits. This cross-sectional study aimed to draw a clinical picture of MSM and their relationships with other findings in patients with IBD. MATERIALS AND METHODS: Patients of our IBD cohort between March 2012 and September 2013 were consecutively evaluated...

BACKGROUND: Contrast-enhanced ultrasound (CEUS) has become an established non-invasive, patient-friendly imaging technique which improves the characterization of lesions. In addition, dynamic contrast-enhanced ultrasound (DCE-US) provides valuable information concerning perfusion of examined organs. This review addresses current applications of CEUS in children, focused on DCE-US of the bowel wall in patients with Crohn disease, which enables realtime assessment of the bowel wall vascularity with semi-quantitative and quantitative assessment of disease activity and response to medical treatment...

Hypertension is an inflammatory condition controlled by the renin angiotensin system and is linked to kidney disease, diabetes mellitus and recently to dysfunction of the gut. The aim of this study was to determine what effect anti-hypertensive drug treatments may have on intestinal function of the spontaneously hypertensive rat (SHR). In the first experiment SHR were treated with enalapril or hydralazine. In the second experiment SHR were treated with losartan with no-treatment as control for both experiments...

Inflammatory bowel disease (IBD) is characterized by a radical imbalance in the activation of proinflammatory and anti-inflammatory signaling pathways in the gut. This study was conducted to evaluate the anti-inflammation effect of miltirone against IBD in vitro and in vivo, and try to explore the underlying mechanisms. Miltirone could extenuate the loss of colon length and weight caused by TNBS. Additionally, macroscopic scores and DAI were reduced significantly compared with the TNBS group. The levels of TNF-α, IL-1β, IL-6 and IL-8 were increased significantly with the induction by TNBS (100mg/kg) or LPS (0...

BACKGROUND: Genome-wide association studies (GWAS) have revealed many susceptibility loci for complex genetic diseases. For most loci, the causal genes have not been identified. Currently, the identification of candidate genes is predominantly based on genes that localize close to or within identified loci. We have recently shown that 92 of the 163 inflammatory bowel disease (IBD)-loci co-localize with non-coding DNA regulatory elements (DREs). Mutations in DREs can contribute to IBD pathogenesis through dysregulation of gene expression...

Increasing knowledge regarding the immunopathogenesis of IBD has led to the development or approval of novel therapeutic agents for the treatment of Crohn's disease or ulcerative colitis. The new substances for example include antibodies against IL-12 / 23, anti-adhesion molecules and antisense oligonucleotides. The increase of therapeutic options will lead to a change of currently used therapeutic algorithms. Biomarkers to ensure a more individualized therapeutic approach are urgently needed to improve an efficient therapy of IBD patients...

Early detection of bowel strangulation is difficult in patients with mechanical bowel obstruction (MBO). There have been no previous reports of predicting strangulation in MBO cases using the delta neutrophil index (DNI), which is a measure of the proportion of circulating immature granulocytes, or the myeloperoxidase index (MPXI), which is a measure of serum myeloperoxidase level. Therefore, we evaluated differences in initial DNI and MPXI upon presentation at the emergency department (ED) according to strangulation presence in MBO patients...

OBJECTIVE: The activation of NF-κB signaling and unbalance of T-helper (Th) cells have been reported to play a key role in the pathogenesis of colitis. Cortex Phellodendri Chinensis (CPC) is commonly used to treat inflammation and diarrhea. Demethyleneberberine (DMB), a component of CPC, was reported to treat alcoholic liver disease as a novel natural mitochondria-targeted antioxidant in our previous study. In this study, we investigated whether DMB could protect against dextran sulfate sodium (DSS)-induced inflammatory colitis in mice by regulation of NF-κB pathway and Th cells homeostatis...

Inflammatory bowel disease (IBD) comprises two distinct conditions: ulcerative colitis and Crohn's disease, both of which are chronic, relapsing disorders carrying significant morbidity, mortality and healthcare costs. With growing attention to coordinated healthcare for patients with chronic systemic diseases, this review focuses on the care of IBD patients in remission, their concerns, quality of life, follow-up, the role of primary care physicians and the IBD-specific aspects of long-term care. We did an extensive PubMed search for articles pertaining to IBD patients in remission and, along with the authors' experience, formulated a comprehensive review...

BACKGROUND: In inflammatory bowel disease (IBD), a new biological therapy has recently been approved. Vedolizumab is a humanised IgG1 monoclonal antibody to α4β7 integrin that modulates gut lymphocyte trafficking. Although an exclusively local effect of vedolizumab could be expected based on the restricted presence of the α4β7-mucosal vascular addressin cell adhesion molecule 1 complex in the gut, past combined success with anti-tumour necrosis factor, and previous demonstration of α4β7 integrin in the joint, led to the expectation of a therapeutic efficacy in spondyloarthritis...

Differential intestinal expression of the macrophage growth factors colony stimulating factor-1 (CSF-1), interleukin (IL)-34, and their shared CSF-1 receptor (CSF-1R) in inflammatory bowel disease (IBD) has been shown. Diverse expression between CSF-1 and IL-34, suggest that IL-34 may signal via an alternate receptor. Receptor-type protein-tyrosine phosphatase ζ (PTPRZ1, RPTP-ζ), an additional IL-34 receptor, was recently identified. Here, we aimed to assess PTPRZ1 expression in IBD and non-IBD intestinal biopsies...
