Background and Summary: Traditionally, functional gastrointestinal disorders (FGID), including functional dyspepsia or irritable bowel syndrome (IBS), are defined by more or less specific symptoms and the absence of structural or biochemical abnormalities that cause these symptoms. This concept is now considered to be outdated; if appropriate tests are applied, structural or biochemical abnormalities that explain or cause the symptoms may be found in many patients. Another feature of FGID are the highly prevalent psychiatric comorbidities, such as depression and anxiety...

Functional dyspepsia (FD) is a gastrointestinal disorder of unknown etiology. Although micro-inflammation appears to be important in the pathogenesis, studies evaluating immune activation in FD have been inconsistent. A systematic review of literature and meta-analysis was performed to compare immunologic cell counts and cytokine levels in the mucosa and peripheral blood of individuals with FD and healthy controls. PubMed, Embase, and the Cochrane library were searched. Data on immunologic cell counts and cytokines levels among individuals with FD and control groups were extracted and compared by calculating standard mean differences (SMD)...

Interleukin (IL)-15 overexpression in eosinophilic gastrointestinal disorders is reported, but IL-15's role in promoting eosinophilic gastroenteritis is largely unknown. Therefore, we generated enterocyte-overexpressed IL-15 transgenic mice using Fabpi promoter. The Fabpi-IL-15 (iIL-15) transgenic mice showed induced IL-15 levels in the jejunum with a marked increase in jejunum eosinophils. However, no induction of eosinophilia in the blood or any other gastrointestinal segment was observed. Eosinophilia in the jejunum villus was substantially higher in iIL-15 mice compared to wild-type mice...

 Eosinophilic gastrointestinal disorders (EGIDs) affect various segments of the gastrointestinal tract. Since these disorders are rare, collaboration is essential to enroll subjects in clinical studies and study the broader population. The Rare Diseases Clinical Research Network (RDCRN), a program of the National Center for Advancing Translational Sciences (NCATS), funded the Consortium of Eosinophilic Gastrointestinal Disease Researchers (CEGIR) in 2014 to advance the field of EGIDs. CEGIR facilitates collaboration among various centers, subspecialties, patients, professional organizations and patient-advocacy groups and includes 14 clinical sites...

Eosinophilic esophagitis (EoE) is a food antigen-mediated disorder of the esophagus characterized by eosinophil predominant inflammation and symptoms of esophageal dysfunction. Dietary antigen elimination induces clinical and histological remission in patients with EoE. The most restrictive of elimination diets (the elemental diet) removes all possible food antigens while empiric elimination diets remove all (or a subset) of food antigens most commonly reported to cause esophageal eosinophilia and food allergies (milk, egg, wheat, soy, peanuts, tree nuts, fish, or legumes)...

Eosinophilic esophagitis (EoE) and celiac disease (CeD) are chronic immune mediated gastrointestinal disorders characterized by mucosal inflammation, both of which are related to food antigens, but with differences in clinical and histopathological features. When untreated, both diseases lead to destruction of the epithelium. While a strict gluten-free diet is the only effective therapy for CeD, several therapeutic options, such as proton pump inhibitors, topical steroids and diet elimination therapy are available for EoE...

Eosinophilic gastrointestinal diseases (EGIDs), including eosinophilic gastroenteritis and eosinophilic colitis, have been increasing in prevalence in Western countries in recent years. Eosinophils are normally scanty in the gastrointestinal tract, and increased numbers of eosinophils can denote pathology. Normal values for tissue eosinophils vary widely between different segments of the colon, thus location of the biopsy is critically important for the interpretation of findings. However, no standard diagnostic criteria have been proposed for the diagnosis of eosinophilic gastroenteritis or eosinophilic colitis...

Dysphagia is a common symptom that is important to recognise and appropriately manage, given that causes include life threatening oesophageal neoplasia, oropharyngeal dysfunction, the risk of aspiration, as well as chronic disabling gastroesophageal reflux (GORD). The predominant causes of dysphagia varies between cohorts depending on the interplay between genetic predisposition and environmental risk factors, and is changing with time. Currently in white Caucasian societies adopting a western lifestyle, obesity is common and thus associated gastroesophageal reflux disease is increasingly diagnosed...

Functional dyspepsia (FD) is a highly prevalent disorder that affects more than 10% of the population. In the past decade, the conceptual underpinning of FD has begun to change, and new data are unraveling the underlying pathophysiological mechanisms of this disorder with a focus on the duodenum. The Rome IV criteria were published in 2016, and notably suggests that gastroesophageal reflux disease and irritable bowel syndrome may all be part of the same disease spectrum as FD. Helicobacter pylori explains a minority of FD cases and in Rome IV is considered a separate entity...

INTRODUCTION: The most common medical conditions in infants, which belong to pediatric and gastroenterological disease areas, are functional gastrointestinal disorders, food hypersensitivity and food allergy. First of all, these symptoms can disguise lactase deficiency, cow's milk protein allergy, eosinophilic gastroenteritis, allergic proctocolitis, gastrointestinal manifestations of atopic dermatitis, functional disorders of gastrointestinal and biliary tract, etc. The aim of our study was to develop an algorithm of monitoring for infants with disorders of the gastrointestinal tract and to study the efficacy of probiotic and enzyme replacement therapy...

Eosinophilic gastrointestinal disorders are a rare and complex group of disorders that are characterized by eosinophilic infiltration of the gastrointestinal tract. Patients often present with a wide range of signs and symptoms as any length or layer of the GI tract can be involved such as mucosal, muscular, or serosal. As a part of the workup, patients frequently undergo computed tomography scans and multiple endoscopies before the diagnosis is finally made as was true in our case of a 59-year-old male patient presenting with 2 months of nausea, abdominal pain, and weight loss...

Eosinophilic gastrointestinal disorder (EGID) is a rare disease in children that affects the bowel wall, with eosinophilic infiltration in the absence of any other causes for eosinophilia. The etiology remains unknown, but allergies and immunological imbalance are suspected triggers. We encountered a case of serosal EGID presenting as intractable vomiting and ascites in a 9-year-old girl, after influenza virus infection. Peripheral eosinophilia was not present. The diagnosis was confirmed by biopsy of the bowel wall through laparotomy and endoscopy, and controlled by 2 courses of steroid therapy due to recurring symptoms...

BACKGROUND: Eosinophilic gastrointestinal disorders (EGIDs) are hypersensitivity disorders frequently triggered by food allergy and manifested by mucosal eosinophilic infiltration at any level of the gastrointestinal tract. This study established a model of gastric eosinophilia in peanut-sensitized piglets to evaluate the efficacy of epicutaneous immunotherapy (EPIT) for its treatment. METHODS: Experiments were carried out in piglets first sensitized by three intra-peritoneal injections of peanut protein extract (PPE) with adjuvant, and then given PPE orally for 10 days, a sequence leading to gastric eosinophilia assessed by endoscopy...

RATIONALE: Eosinphilic gastroenteritis (EG) is a gastrointestinal disorder characterized by eosinophilic infiltration with various manifestations. The diagnosis is usually confirmed by an endoscopic biopsy, which is considered a safe and routine procedure for the majority. PATIENT CONCERNS: We report a 54-year-old male who was presented with intermittent periumbilical pain and melena, and only revealed verrucous gastritis by endoscopy. DIAGNOSES: The patient's condition worsened two days after the endoscopic biopsy, and another endoscopy found hematoma and ulcers in upper gastrointestinal tract...

Angelman syndrome (AS) is a neurogenetic disorder characterized by intellectual disability, expressive speech impairment, movement disorder, epilepsy, and a happy demeanor. Children with AS are frequently reported to be poor feeders during infancy and as having gastrointestinal issues such as constipation, reflux, and abnormal food related behaviors throughout their lifetime. To assess the prevalence of gastrointestinal disorders in individuals with AS, we retrospectively analyzed medical records of 120 individuals seen at the Angelman Syndrome Clinic at Massachusetts General Hospital and 43 individuals seen at the University of North Carolina Comprehensive Angelman Clinic...

Human mast cells (MCs) and eosinophils were first described and named by Paul Ehrlich. These cells have distinct myeloid progenitors and differ morphologically, ultrastructurally, immunologically, biochemically, and pharmacologically. However, MCs and eosinophils play a pivotal role in several allergic disorders. In addition, these cells are involved in autoimmune disorders, cardiovascular diseases, and cancer. MCs are distributed throughout all normal human tissues, whereas eosinophils are present only in gastrointestinal tract, secondary lymphoid tissues, and adipose tissue, thymus, mammary gland, and uterus...
