The most interesting conclusions and/or advances presented at Digestive Disease Week 2016 were the following: a) gastroesophageal reflux disease: proton pump inhibitor-refractory reflux disease is frequently associated with poor treatment adherence, psychiatric comorbidities and functional gastrointestinal disorders. These possible entities should be investigated in all cases of proton pump inhibitor-refractory reflux disease; b) Barrett's oesophagus: the efficacy of screening remains unclear; however, new minimally-invasive techniques such as the cytosponge allow more effective detection, both of Barrett's oesophagus and Barrett's oesophagus-associated dysplasia or neoplasia; c) achalasia: evidence indicates that peroral endoscopic myotomy is as effective as surgery and is a safer alternative; d) eosinophilic oesophagitis: high-dose proton pump inhibitors are required to rule out proton pump inhibitor-responsive eosinophilic oesophagitis; montelukast is not clearly effective in the treatment of eosinophilic oesophagitis, although moderate efficacy cannot be ruled out...

Eosinophilic gastroenteritis is a rare inflammatory disorder of the gastrointestinal tract with an estimated prevalence of one in 100,000. The typical presentation consists of vague gastrointestinal symptoms with the mucosal involvement of the digestive system. Rarely, it presents as eosinophilic ascites. We report the case of a 22-year-old female who presented with acute onset abdominal pain and ascites. The laboratory studies were remarkable for eosinophilia and the ascitic fluid demonstrated high eosinophilic counts...

Functional dyspepsia (FD) is a functional gastrointestinal disorder diagnosed by symptom-based criteria. It has been said that duodenal immune activation plays a role in the pathogenesis of FD. The primary aims of the study were to compare the total number of duodenal eosinophil and evaluate the eosinophil degranulation rate, number of duodenal degranulated eosinophil and mast cell between patients with FD and healthy subjects. We enrolled 96 patients with FD and 24 healthy controls at Sir Run Run Shaw Hospital...

Eosinophils are native to the healthy gastrointestinal tract and are associated with inflammatory diseases likely triggered by exposure to food allergens (e.g., food allergies and eosinophilic gastrointestinal disorders). In models of allergic respiratory diseases and in vitro studies, direct Ag engagement elicits eosinophil effector functions, including degranulation and Ag presentation. However, it was not known whether intestinal tissue eosinophils that are separated from luminal food Ags by a columnar epithelium might similarly engage food Ags...

KMP6 (Pyeongwee-San) is a Korean Medicine used to treat gastrointestinal disorders. Recently, we reported KMP6 had beneficial effects on allergic inflammatory diseases. The aim of this study was to evaluate the effects of atractylone (Atr), a constituent of KMP6, on allergic rhinitis (AR) and to identify the mechanism responsible for these effects. The anti-allergic inflammatory effects of Atr were evaluated on phorbol 12-myristate 13-acetate and calcium ionophore A23187 (PMACI)-stimulated human mast cell line, HMC-1 cells and in an ovalbumin (OVA)-induced AR animal model using Western blotting, quantitative real-time PCR, ELISA, and immunohistochemistry methods...

BACKGROUND: Food oral immunotherapy (OIT) involves the administration of the food allergen causing the symptoms, in order to induce tolerance. Primary eosinophilic gastrointestinal disorders (PEGDs) are characterised by an eosinophil-rich inflammation affecting different locations of the digestive tract. We present a series of patients with PEGDs in a group of children following OIT with milk and/or egg. MATERIAL AND METHODS: A prospective study during the period 2006-2014 was performed in paediatric patients subjected to OIT with milk and/or egg...

Eosinophilic gastrointestinal disorders represent a spectrum of disorders demonstrating gastrointestinal eosinophilia without any known cause for eosinophilia. Pathogenesis is not clearly established, but immune responses to dietary antigens are implicated. These disorders affect children and adults and are seen in association with allergic disorders. Eosinophilic esophagitis is diagnosed in the setting of mucosal eosinophilia on endoscopic biopsy and symptoms of esophageal dysfunction. Eosinophilic gastroenteritis is also diagnosed with endoscopic biopsies...

Muscularis propria throughout the entire gastrointestinal tract including the esophagus is comprised of circular and longitudinal muscle layers. Based on the studies conducted in the colon and the small intestine, for more than a century, it has been debated whether the two muscle layers contract synchronously or reciprocally during the ascending contraction and descending relaxation of the peristaltic reflex. Recent studies in the esophagus and colon prove that the two muscle layers indeed contract and relax together in almost perfect synchrony during ascending contraction and descending relaxation of the peristaltic reflex, respectively...

Eosinophilic gastroenteritis (EGE) is a rare disease which belongs to primary eosinophilic gastrointestinal disorders (primary EGIDs), characterized by an accumulation of eosinophils in the gastrointestinal (GI) tract and is strongly associated with atopy and allergy. The clinical presentations vary depending on the site and depth of eosinophilic intestinal infiltration. Radiology pictures may show irregular thickening of the folds, but these findings can also be present in other conditions like inflammatory bowel disease and lymphoma...

BACKGROUND: Parkinson's disease (PD) is frequently associated with gastrointestinal (GI) symptoms, including constipation and defecatory dysfunctions. The mechanisms underlying such disorders are still largely unknown, although the occurrence of a bowel inflammatory condition has been hypothesized. This study examined the impact of central dopaminergic degeneration, induced by intranigral injection of 6-hydroxydopamine (6-OHDA), on distal colonic excitatory tachykininergic motility in rats...

Eosinophilic gastroenteritis (EGE) is a rare inflammatory disorder of gastrointestinal tract characterized by eosinophilic infiltration of the bowel wall. It can mimic many gastrointestinal disorders due to its wide spectrum of presentations. Diagnose is mostly based on excluding other disorders and a high suspicion. Here we report a case of 26 year old man with a history of sever epigastric pain followed by nausea, vomiting since a few days before admission with final diagnosis of EGE.

BACKGROUND AND AIM: Eosinophilic esophagitis (EoE) is a Th2-mediated allergic disease of the esophageal epithelium, associated with antigen. We previously reported a case series for eosinophilic esophageal myositis (EoEM)-a novel eosinophilic gastrointestinal disorder (EoGID) defined as eosinophilic infiltration localized in the esophageal muscle layer-and diagnosed it by peroral endoscopic muscle biopsy. Here, we investigated the immunopathology of EoEM to differentiate it from EoE. METHODS: Histological analysis was performed for three cases of EoEM and EoE, respectively...

Endoscopic examination of the gastrointestinal tract (GIT) for diagnostics and therapy in children has evolved markedly over the last 20 or so years and is now usually undertaken by paediatric endoscopists. Updated diagnostic and management guidelines for common disorders including coeliac disease, gastro-oesophageal reflux disease, eosinophilic oesophagitis and inflammatory bowel disease highlight the central role of endoscopy. Therapeutic endoscopic approaches are also now widely available and further broaden the referral spectrum to include treatment of GIT bleeding, gastrostomy insertion, dilation of strictures and polypectomy...

INTRODUCTION: Eosinophilic gastrointestinal disorders (EGIDs) are increasingly prevalent chronic inflammatory diseases characterized by eosinophilic infiltration of the gastrointestinal (GI) tract, in the absence of other known causes of eosinophilia. AREAS COVERED: Clinical management of EGIDs is challenging, as there are currently limited therapeutic options available. The most common EGID is eosinophilic esophagitis (EoE), and rarer forms are eosinophilic gastritis, eosinophilic gastroenteritis, and eosinophilic colitis...

BACKGROUND: Eosinophilic esophagitis (EoE) is related to allergic diseases such as bronchial asthma (BA), atopic dermatitis, and allergic rhinitis. The aim of this study was to examine the eosinophil infiltration in the upper gastrointestinal (GI) tract in patients with BA using esophagogastroduodenoscopy. METHODS: Patients with BA who had upper GI tract symptoms were enrolled. Patients who received systemically administered steroids were excluded. Eosinophil infiltrations in the esophagus, stomach, and duodenum were examined with regard to the endoscopic findings and pathological findings of biopsy specimens (UMIN000010132)...

BACKGROUND/AIMS: Abdominal pain-related functional gastrointestinal disorder (AP-FGID) is common in children and adults. However, the mechanism of AP-FGID is not clearly known. Recently, micro-inflammation, especially eosinophilia in the gastrointestinal tract, was suggested in the pathophysiology of AP-FGID in adults. The aim of this study was to evaluate the association of gastric and duodenal eosinophilia with pediatric AP-FGID. METHODS: In total, 105 pediatric patients with AP-FGID were recruited and classified into 4 subgroups based on the Rome III criteria...
