INTRODUCTION: MicroRNAs (miRs) came recently into focus as promising novel research targets offering new insights into the pathogenesis of inflammatory bowel diseases (IBD). AIMS: The aim of our study was to identify a pediatric IBD (pIBD) characteristic miR profile serving as potential Crohn's disease (CD) and ulcerative colitis (UC) specific diagnostic pattern and to further analyze the related target genes. METHODS: Small RNA sequencing was performed on inflamed and intact colonic biopsies of CD, and control patients...

Amicrobial pustulosis of the folds (APF) is a rare disease characterized by aseptic pustular lesions involving cutaneous folds, typically occurring in the context of an autoimmune disorder. We present 4 patients with APF, focusing on clinical and histopathologic characteristics to improve the recognition of this entity. All 4 patients had intertriginous and extra-intertriginous involvement. Common histopathologic features of skin biopsies in these patients were intracorneal, subcorneal, intraepidermal, perivascular, perifollicular, and interstitial neutrophilic inflammation...

Telocytes are a peculiar stromal (interstitial) cell type implicated in tissue homeostasis and development, as well as in the pathophysiology of several disorders. Severe damage and reduction of telocytes have been reported during fibrotic remodeling of multiple organs in various diseases, including scleroderma, Crohn's disease, ulcerative colitis, and liver fibrosis, as well as in chronic inflammatory lesions like those of primary Sjögren's syndrome and psoriasis. Owing to their close relationship with stem cells, telocytes are also supposed to contribute to tissue repair/regeneration...

BACKGROUND: Exclusive enteral nutrition (EEN) is a first-line therapy in pediatric Crohn's disease (CD) thought to induce remission through changes in the gut microbiome. With microbiome assessment largely focused on microbial taxonomy and diversity, it remains unclear to what extent EEN induces functional changes that thereby contribute to its therapeutic effect. METHODS: Fecal samples were collected from 15 pediatric CD patients prior to and after EEN treatment, as well as from 5 healthy controls...

Patients with inflammatory Bowel Disease (IBD) often require hospitalization and this experience is stressful. Health care providers frequently do not have adequate time to address the emotional impact of the hospitalization on the patient and family. Nonmedical support for inpatients was identified as an unmet need by a Crohn's disease patient's family. This led to the development of a volunteer peer specialist network, IBD Connect, where peer volunteers visit hospitalized patients with IBD to offer emotional support and educational materials...

To date there is a major effort in deciphering the role of complex microbial communities, especially the oral and gut microbiomes, in the pathogenesis of various diseases. Increasing evidence indicates a key role for the oral microbiome in autoimmune diseases. In this review article, we discuss links of the oral microbiota to a group of autoimmune diseases, i.e., Sjögren's syndrome (SS), systemic lupus erythematosus (SLE), Crohn's disease (CD), and rheumatoid arthritis (RA). We particularly focus on factors that affect the balance between the immune system and the composition of microbiota leading to dysbiosis, loss of tolerance and subsequent autoimmune disease progression and maintenance...

BACKGROUND: Immune-mediated inflammatory diseases (IMIDs) are a group of complex and prevalent diseases where disease diagnostic and activity monitoring is highly challenging. The determination of the metabolite profiles of biological samples is becoming a powerful approach to identify new biomarkers of clinical utility. In order to identify new metabolite biomarkers of diagnosis and disease activity, we have performed the first large-scale profiling of the urine metabolome of the six most prevalent IMIDs: rheumatoid arthritis, psoriatic arthritis, psoriasis, systemic lupus erythematosus, Crohn's disease, and ulcerative colitis...

Inflammatory bowel disease (IBD) has become a 'prototype disease' for chronic auto-inflammatory disorders with a polygenic background and important multifaceted environmental trigger components. The environmental factors contribute both to pathogenesis and disease flares. Thus, IBD is a disease par excellence to study the interactions between host genetics, environmental factors (such as infections or smoking) and 'in-vironmental' factors - for example, our intestinal microbiota. Longitudinal intercurrent events, including the impact of long-term medication on disease progression or stabilization, can exemplarily be studied in this disease group...

Numerous reviews have discussed gut microbiota composition changes during inflammatory bowel diseases (IBD), particularly Crohn's disease (CD). However, most studies address the observed effects by focusing on studying the univariate connection between disease and dietary-induced alterations to gut microbiota composition. The possibility that these effects may reflect a number of other interconnected (i.e., pantropic) mechanisms, activated in parallel, particularly concerning various bacterial metabolites, is in the process of being elucidated...

OBJECTIVES: Tantalizing connections between autoimmune rheumatic diseases (ARDs) and inflammatory bowel disease (IBD) have become evident with regard to their genetic and immunologic background. However, the association between these two disease entities remains unclear. The aim of this study is to investigate the association between each ARD and IBD. METHODS: A nationwide population-based cross-sectional study was performed using the Korean National Health Insurance Claims database...

Inflammatory bowel diseases (IBDs) often present as a complex inflammatory process wherein colon lesions (ulcerative colitis, UC) or widespread ulceration and fissure (Crohn's disease, CD) might be accompanied by ancillary extraintestinal manifestations (EIMs) that could involve almost every organ system, but also by autoimmune disorders ranging from psoriasis and rheumatoid arthritis to connective tissue diseases. Certain EIMs are more common related to the activity of the IBD (joint, skin, ocular and oral manifestations), other EIMs typically run a course independent of the IBD activity (hepatobiliary disorders) and some are non-specific disorders (osteoporosis and amyloidosis)...

BACKGROUND/AIMS: C-reactive protein (CRP) is an easily measured index of disease activity, but its ability to predict clinical course is controversial. We therefore designed a study to determine whether the CRP level at Crohn's disease (CD) diagnosis is a valuable indicator of the disease phenotype, activity, and clinical course. METHODS: We retrospectively analyzed 705 CD patients from 32 institutions. The patients were classified into two groups according to CRP level...

Chronic inflammatory enteropathies, including celiac disease, Crohn's disease, and ulcerative colitis, are lifelong disabling conditions whose cure is still an unmet need, despite the great strides made in understanding their complex pathogenesis. The advent of cellular therapies, mainly based on the use of stem cells, represents a great step forward thanks to their multitarget strategy. Both hematopoietic stem cells (HSC) and mesenchymal stem/stromal cells (MSC) have been employed in the treatment of refractory cases with promising results...

Bacterial trafficking from gut to mesenteric lymph nodes is physiologic only for a few commensal species, like Alcaligenes which produces antimicrobial-substances inhibiting growth of pathogenic bacteria. In reactive arthritis, some living bacteria transiently manage to travel from gut to joints/enthesis within dendritic cells and/or macrophages. Migration of dead or dormant bacteria outside the gut in spondyloarthropathies, including those associated with Crohn's disease, can occur either through blood or lymphatics...

Background and Aim. Crohn's disease is associated with gut microbiota (GM) dysbiosis. Treatment with the anti-IL-12p40 monoclonal antibody (12p40-mAb) has therapeutic effect in Crohn's disease patients. This study addresses whether a 12p40-mAb treatment influences gut microbiota (GM) composition in mice with adoptive transfer colitis (AdTr-colitis). Methods. AdTr-colitis mice were treated with 12p40-mAb or rat-IgG2a or NaCl from days 21 to 47. Disease was monitored by changes in body weight, stool, endoscopic and histopathology scores, immunohistochemistry, and colonic cytokine/chemokine profiles...

Idiopathic inflammatory bowel diseases (IBD), Crohn's disease (CD) and ulcerative colitis (UC), are multifactorial diseases that are manifested after disruption of a genetic predisposed individual and its intestinal microflora through an environmental stimulus. Urbanization and industrialization are associated with IBD. Epidemiological data, clinical observations and family/immigrants studies indicate the significance of environmental influence in the development of IBD. Some environmental factors have a different effect on the subtypes of IBD...

BACKGROUND: To identify and develop novel targeted therapies for complex diseases such as Crohn's disease (CD), functional subtypes rooted in pathogenesis must be defined. One candidate method to subtype CD is to define the small intestinal Paneth cell phenotypes based on the intracellular distribution of antimicrobial proteins. We have previously shown that in CD patients, Paneth cell phenotype correlates with the patients' genotype, distinct gene expression signature, presence of granuloma (pathologic hallmark), and time to recurrence after surgery...

Diagnostic delay frequently occurs in Crohn's disease (CD) patients because of diagnostic limitations. However, diagnostic delay and its related factors remain poorly defined. Therefore, we aimed to identify the predictors associated with diagnostic delay and to evaluate the impact of diagnostic delay on clinical course in a Korean CD patient cohort. We performed a multicenter retrospective analysis of 1,047 CD patients registered in the Crohn's Disease Clinical Network and Cohort study in Korea. The mean interval of diagnostic delay was 16...

For many patients with autoimmune hepatitis (AIH), the presence of extrahepatic features is well recognised both at the time of presentation and during long-term follow-up. Concomitant 'autoimmune disorders' have been described in 20-50% of patients with AIH, both in adults and children. Indeed, the presence of these associated phenomena has been incorporated into both the original and revised International AIH group scoring systems as an aid to codifying the diagnosis. In acute index presentations, non-specific joint pains sometimes flitting in nature have been reported in 10-60% of patients, and while joint swelling is uncommon, rheumatoid arthritis and mixed connective tissue disease have been reported in 2-4% of patients with AIH...
