Ultrasound (US) is the first-line investigation in patients with abdominal symptoms and it has a role in the diagnosis and monitoring of inflammatory bowel diseases. Strain elastography (SE) is a US method for estimating tissue elasticity. This method is still not routinely used in clinical practice, although it is suggested by the EFSUMB Guidelines for the characterization of intestinal stenosis in Crohn's disease. The purpose of this Pictorial Essay is to confirm the feasibility of elastography in Crohn's disease in clinical practice by comparing elastography images with corresponding endoscopic or radiological images...

Purpose. Squamous cell carcinoma (SCC) developing within fistulae and chronic wounds in patients with Crohn's disease is a rare phenomenon with few reported studies in the literature. Clinical suspicion for SCC in Crohn's disease patients with chronic painful fistulae is low, leading to delayed diagnosis and treatment. We present a patient with long-standing Crohn's disease complicated by malignant degeneration of an enterocutaneous fistula tract. Methods. Workup with MRI, CT, and fistulogram revealed a 7 × 3 cm fistulous connection between a loop of small intestine and the patient's perineum...

OBJECTIVES: Orofacial granulomatosis (OFG) is a chronic inflammatory condition affecting the orofacial area. Its connection to Crohn's disease (CD) is debated. Our aim was to describe a cohort of pediatric OFG patients in detail, study the long-term behavior of OFG and evaluate factors predicting CD in OFG patients. METHODS: We invited patients diagnosed with OFG at two university hospitals, Finland for a follow-up appointment. Patients (n = 29) were examined by a dentist and an otorhinolaryngologist using a structural schema...

BACKGROUND: A considerable number of patients with Crohn's disease (CD) develop irreversible intestinal damage, although the early administration of immunomodulatory or biological therapies might prevent this. The aims of our study were to develop and validate a novel predictive model that can be used to predict the risk of surgical intervention in Korean patients with CD. METHODS: The prognostic model was derived from the multicenter longitudinal CONNECT (CrOhn's disease cliNical NEtwork and CohorT) study cohort consisting of 1338 patients with CD, who were split into training and validation sets...

BACKGROUND. Morphological patterns of Paneth cells are a prognostic biomarker in Western Crohn's disease (CD) patients, and are associated with autophagy-associated ATG16L1 and NOD2 variants. We hypothesized that genetic determinants of Paneth cell phenotype in other ethnic CD cohorts are distinct but also involved in autophagy. METHODS. We performed a hypothesis-driven analysis of 56 single nucleotide polymorphisms (SNPs) associated with CD susceptibility or known to affect Paneth cell function in 110 Japanese CD patients who underwent ileal resection...

BACKGROUND: Inflammatory bowel disease can develop in the context of some rheumatic diseases in childhood, including juvenile idiopathic arthritis (JIA). Inflammatory bowel disease (IBD) is frequently associated with other immune-mediated diseases; however, systemic onset JIA (sJIA) has not previously been connected to IBD. Treatment of sJIA has significantly changed in recent years, possibly causing changes in inflammatory patterns. Therefore, data from the German Center for Pediatric and Adolescent Rheumtology from 2010 until 2015 were analyzed by retrospective chart review...

The most prevalent diseases manifested by Escherichia coli are acute and recurrent bladder infections and chronic inflammatory bowel diseases such as Crohn's disease. E. coli clinical isolates express the FimH adhesin, which consists of a mannose-specific lectin domain connected via a pilin domain to the tip of type 1 pili. Although the isolated FimH lectin domain has affinities in the nanomolar range for all high-mannosidic glycans, differentiation between these glycans is based on their capacity to form predominantly hydrophobic interactions within the tyrosine gate at the entrance to the binding pocket...

BACKGROUND: Inflammatory bowel diseases (IBD) are severe medical conditions with adverse impact on the quality of life of both children and their caregivers. IBD are associated with many limitations in personal and interpersonal functioning, and it also restricts the patients' ability to use the full potential (extent) of their capabilities. With the progress and humanization in society, the issue of patients' needs became an important topic; however, the psychosocial functioning and quality of life of adolescents suffering from IBD and their caregivers have been understudied...

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...
