Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, is a chronic intestinal inflammatory condition initiated by integrins-mediated leukocyte adhesion to the activated colonic microvascular endothelium. Calreticulin (CRT), a calcium-binding chaperone, is known as a partner in the activation of integrin α subunits (ITGAs). The relationship between their interaction and the pathogenesis of IBD is largely unknown. Here we show that a small molecule, orally active ER-464195-01, inhibits the CRT binding to ITGAs, which suppresses the adhesiveness of both T cells and neutrophils...

AIMS: Serrated lesions (SLs), including sessile serrated adenoma (SSA) and traditional serrated adenoma (TSA), are important premalignant lesions for colorectal cancer (CRC). Although a small subset of SLs are known to harbor TP53 mutations and Wnt/β-catenin pathway activation, suggesting that they may develop dysplasia or CRC via a 'chromosomal instability (CIN)-like' pathway, it is unclear if aneuploidy (characteristic of conventional adenoma) ever develops in SLs and is associated with development of dysplasia or CRC, in this context...

CONTEXT: Review of the yeast Saccharomyces boulardii as a treatment option for the inflammatory bowel diseases (IBD) ulcerative colitis and Crohn's disease. OBJECTIVE: IBD is caused by an inappropriate immune response to gut microbiota. Treatment options could therefore be prebiotics, probiotics, antibiotics and/or fecal transplant. In this review, we have looked at the evidence for the yeast S. boulardii as a treatment option. MATERIAL AND METHODS: Searches in PubMed and the Cochrane Library with the MeSH words 'Saccharomyces boulardii AND IBD', 'Saccharomyces boulardii AND Inflammatory Bowel Disease', 'Saccharomyces boulardii AND ulcerative colitis' and 'Saccharomyces boulardii AND Crohn's disease' gave total a total of 80 articles...

BACKGROUND: Although many predictive factors for postoperative morbidity are known, few data are available about readmission after abdominal surgery for Crohn's disease (CD). The objective of this study is to identify predictive factors and high-risk patients for readmission after abdominal CD surgery. METHODS: All patients who underwent abdominal surgery for CD in one tertiary referral center between January 2004 and December 2016 were included. Patients who required readmission and those without were compared...

BACKGROUND: The American Association for the Surgery of Trauma (AAST) anatomic severity grading system for adhesive small bowel obstruction (ASBO) has demonstrated to be a valid tool in North American patient populations. Using a multi-national patient cohort, we retrospectively assessed the validity the AAST ASBO grading system and estimated disease severity in a global population in order to correlate with several key clinical outcomes. METHODS: Multicenter retrospective review during 2012-2016 from four centers, Minnesota USA, Bologna Italy, Pietermaritzburg South Africa, and Bucharest Romania, was performed...

Integrins are cell surface receptors with bi-directional signaling capabilities that can bind to adhesion molecules in order to mediate homing of leukocytes to peripheral tissues. Gut-selective leukocyte homing is facilitated by interactions between α4β7 and its ligand MAdCAM-1, while retention of lymphocytes in mucosal tissues is mediated by αEβ7 binding to its ligand E-cadherin. Therapies targeting gut-selective trafficking have shown efficacy in inflammatory bowel disease (IBD), confirming the importance of leukocyte trafficking in disease pathobiology...

BACKGROUND AND OBJECTIVE: Melkersson Rosenthal syndrome (MRS) is a rare disorder of unknown etiology and comprises the triad: orofacial edema, recurrent facial paralysis and lingua plicata. In the current literature confusing heterogeneity exists, mixing together the historically grown terms cheilitis granulomatosa or granulomatous cheilitis, Melkersson Rosenthal syndrome and the umbrella term orofacial granulomatosis (OFG). METHODS: We provide a systematic review comprising all three disease entities of orofacial granulomatosis using the computerized database "Pubmed Medline" entering the key words "orofacial granulomatosis" (141 references), "Melkersson-Rosenthal syndrome" (207 references), "granulomatous cheilitis" or "cheilitis granulomatosa" (102 references) back to 1956...

Crohns disease (CD) and ulcerative colitis (UC) belong to chronic inflammatory bowel diseases, which are induced by autoimmune processes. While CD is characterized by over-activity of Th1, ILC1, and MAIT cells, UC is mediated by exaggerated activities of Th2 and ILC2 cells and cytokines they produce. Knowledge of the pathogenesis enabled a rational therapy based mostly on biologics and small molecules. TNF is the principal proinflammatory cytokine in both diseases. Anti-TNF monoclonal antibodies, mostly infliximab or adalimumab were therefore introduced to their treatment...

Ileostomy formation is a fundamental component in the surgical management of many gastrointestinal diseases and like all intra-abdominal surgeries, small bowel obstruction is a recognized complication. In this paper we discuss a case of a 44-year-old female who previously had a loop ileostomy for slow bowel transit in the presence of spinal bifida. She presented for subsequent total colectomy because of ongoing pain due to chronic colonic dilation. At surgery, the stoma was not revised and the efferent loop was divided at the peritoneal level of the anterior abdominal wall...

A 27-year-old woman presented to the emergency department with a 24-hour history of severe left iliac fossa pain associated with vomiting. She reported a history of ovarian cysts and was provisionally diagnosed with a ruptured ovarian cyst and admitted under the obstetrics and gynaecology team for further investigation. 24 hours later, she became haemodynamically unstable with increasing abdominal distention and developed a metabolic acidosis. A CT scan revealed large bowel obstruction (LBO) secondary to a faecal bolus in the sigmoid colon with appearances suggestive of adult-onset Hirschsprung's disease...

BACKGROUND: Inguinal hernia is one of the most common benign pathologies that primarily affects men. Primary gastrointestinal non-Hodgkin's lymphoma (PGI NHL) is the most common type of extranodal lymphoma. This study reports a rare case in which these two conditions co-exist. CASE PRESENTATION: An 85-year-old male complained of bowel movement pattern change, abdominal distension and loss of weight, without vomiting but with nausea. A computed tomographic scan of the abdomen showed a small bowel obstruction caused by a migration of a small bowel loop in the right inguinal canal, with a clinically non-reducible inguinal hernia...

Short bowel syndrome with intestinal failure is a rare disease with a massive impairment in quality of life, requiring a multidisciplinary team approach to medical, surgical, and nutritional therapy. Current pharmacological and surgical therapeutic options are limited; an important cornerstone is enteral and parenteral nutrition. The changed physiology of carbohydrate digestion plays a major role in the adaptation process and can be a target for specific enteral nutrition interventions. An important prognostic factor is the preservation of at least portions of the colon in continuity with small bowel...

BACKGROUND: Common mechanisms against small intestinal bacterial overgrowth (SIBO), including an intact ileocecal valve, gastric acid secretion, intestinal motility, and an intact immune system, are compromised in inflammatory bowel disease (IBD), and therefore, a relatively high incidence of SIBO has been reported in this population. AIMS: We aimed to determine whether an improvement in IBD clinical activity scores is seen after testing and treating SIBO. METHODS: A retrospective cohort study of 147 patients with inflammatory bowel disease who were referred for SIBO breath testing from 1/2012 to 5/2016 was performed...

Purpose of review: The intestine contains the largest compartment of immune regulatory cells which include T regulatory cells and IL-10 producing macrophages. These cell populations serve to restrain unnecessary immune responses of the intestine, which may lead to the pathogenesis of Crohn's disease or food allergy. Recent findings: This review discusses the recent findings pertaining to the functional regulation of these cells which may provide insight into novel therapies...

INTRODUCTION: Small bowel malignancies are rare and often present with non-specific symptoms. Because of this, diagnosis of small bowel malignancies is often missed. PRESENTATION OF CASE: 71-year-old male presented with a four-week history of right iliac fossa pain and loss of weight. Laboratory tests showed a raised C-reactive protein, but all other pathology results and tumour-associated antigens were normal. Computed tomography (CT) of the abdomen demonstrated an inflammatory mass extending laterally into the pelvic wall...

BACKGROUND: How to evaluate the prognostic significance of lymphatic metastasis in patients with small bowel (jejunoileal) neuroendocrine tumors (SBNETs) is still not conclusive. METHODS: Data for patients with SBNETs, but without distant metastasis, were retrieved from the Surveillance, Epidemiology, and End Results database. Recursive partitioning analysis (RPA) was used for classification development by combining examined lymph nodes (ELNs) and lymph node ratio (LNR)...

PURPOSE: Interleukin-6 (IL-6) production and signalling are increased in the inflamed mucosa in inflammatory bowel diseases (IBD). As published serum levels of IL-6 and its soluble receptors sIL-6R and sgp130 in IBD are from small cohorts and partly contradictory, we systematically evaluated IL-6, sIL-6R and sgp130 levels as markers of disease activity in Crohn's disease (CD) and ulcerative colitis (UC). METHODS: Consecutive adult outpatients with confirmed CD or UC were included, and their disease activity and medication were monitored...

Olfactomedin-4 (OLFM4, GW112, hGC-1) is a glycoprotein belonging to the olfactomedin family. The expression of OLFM4 is strong in the small intestine, colon and prostate, and moderate in the stomach and bone marrow. Previous studies have revealed that OLFM4 is closely associated with many digestive diseases. Up-regulation of OLFM4 has been detected in the Helicobacter pylori ( H. pylori )-infected gastric mucosa, inflammatory bowel disease tissue and gastrointestinal malignancies, including gastric cancer, colorectal cancer, pancreatic cancer and gallbladder cancer...

REVIEW

Symptomatic intestinal strictures develop in more than one third of patients with Crohn's disease (CD) within 10 years of disease onset. Strictures can be inflammatory, fibrotic or mixed and result in a significant decline in quality of life, frequently requiring surgery for palliation of symptoms. Patients under the age of 40 with perianal disease are more likely to suffer from disabling ileocolonic disease thus may have a greater risk for fibrostenotic strictures. Treatment options for fibrostenotic strictures are limited to endoscopic and surgical therapy...
