Abstract
Eosinophilic colitis (EC) is the rarest among primary eosinophilic gastrointestinal disorders (EGID). EC is underdiagnosed due to its blurred and proteiform clinical manifestations. To explore the clinical and atopic characteristic of EC adult patients, the diagnostic delay, and relapse-associated factors, by comparison with patients with eosinophilic esophagitis (EoE) and irritable bowel syndrome (IBS). EC patients followed-up at four clinics were included, and clinical, histopathological, and laboratory data were retrieved. As control groups, age-matched patients with EoE and IBS were recruited. Allergy tests included skin prick test and serum specific IgE. Diagnostic delay was assessed. Overall, data from 73 patients were retrieved, including 40 with EC (median age 39 years IQR 22.5-59, F:M 2.1:1), 12 with EoE (F:M ratio: 1:5), and 21 with IBS (F:M ratio: 1:0.9). The most common features in EC patients were female sex (67.5%), atopy (77.5%), abdominal pain/distention (70%), diarrhoea (77.5%), and faecal calprotectin elevation (22.5%). Blood eosinophils were elevated in EoE, but not in EC (p < 0.001), while ECP did not differ across the three groups (p = 0.4). The frequency of allergen sensitization reached 25% of patients. Several frequent pan-allergens for this region were present. The overall diagnostic delay was 10 months (IQR 4-15). Factors contributing to a greater diagnostic delay were atopy, weight loss, and a previous misdiagnosis. EC is mostly a diagnosis of exclusion, burdened by a substantial diagnostic delay. In female patients the presence of allergen sensitization, abdominal symptoms and faecal calprotectin elevation should raise the suspicion of EC.

Abstract
Diagnosing gastrointestinal (GI) disorders, which affect parts of the digestive system such as the stomach and intestines, can be difficult even for experienced gastroenterologists due to the variety of ways these conditions present. Early diagnosis is critical for successful treatment, but the review process is time-consuming and labor-intensive. Computer-aided diagnostic (CAD) methods provide a solution by automating diagnosis, saving time, reducing workload, and lowering the likelihood of missing critical signs. In recent years, machine learning and deep learning approaches have been used to develop many CAD systems to address this issue. However, existing systems need to be improved for better safety and reliability on larger datasets before they can be used in medical diagnostics. In our study, we developed an effective CAD system for classifying eight types of GI images by combining transfer learning with an attention mechanism. Our experimental results show that ConvNeXt is an effective pre-trained network for feature extraction, and ConvNeXt+Attention (our proposed method) is a robust CAD system that outperforms other cutting-edge approaches. Our proposed method had an area under the receiver operating characteristic curve of 0.9997 and an area under the precision-recall curve of 0.9973, indicating excellent performance. The conclusion regarding the effectiveness of the system was also supported by the values of other evaluation metrics.

Abstract
Eosinophilic gastrointestinal disorders (EGIDs) are becoming more common causing significant suffering and reduced quality of life. These conditions can affect different parts of the digestive system, either individually or in combination. Recognition of their link to allergic disorders or other gastrointestinal (GI) diseases has raised questions about their shared underlying mechanisms, which has had implications for diagnosis and management. The authors critically examine the current understanding of the connection between EGIDs and allergic conditions (ie, atopic dermatitis, allergic rhinitis, asthma, and food allergy) and GI diseases (ie, inflammatory bowel disease, celiac disease, gastroesophageal reflux disease, and motility disorders).

Abstract
Background Eosinophilic esophagitis (EoE) is a complex allergic condition frequently accompanied by various atopic comorbidities in children, which significantly affects their life qualities. Therefore, this study aimed to evaluate pivotal molecular markers that may facilitate the diagnosis of EoE in pediatric patients. Methods Three available EoE-associated gene expression datasets in children: GSE184182, GSE 197702, GSE55794, along with GSE173895 were downloaded from the GEO database. Differentially expressed genes (DEGs) identified by "limma" were intersected with key module genes identified by weighted gene co-expression network analysis (WGCNA), and the shared genes went through functional enrichment analysis. The protein-protein interaction (PPI) network and the machine learning algorithms: least absolute shrinkage and selection operator (LASSO), random forest (RF), and XGBoost were used to reveal candidate diagnostic markers for EoE. The receiver operating characteristic (ROC) curve showed the efficacy of differential diagnosis of this marker, along with online databases predicting its molecular regulatory network. Finally, we performed gene set enrichment analysis (GSEA) and assessed immune cell infiltration of EoE/control samples by using the CIBERSORT algorithm. The correlations between the key diagnostic biomarker and immune cells were also investigated. Results The intersection of 936 DEGs and 1446 key module genes in EoE generated 567 genes, which were primarily enriched in immune regulation. Following the construction of the PPI network and filtration by machine learning, CXCR2 served as a potential diagnostic biomarker of pediatric EoE with a perfect diagnostic efficacy (AUC = ~1.00) in regional tissue/peripheral whole blood samples. Multiple infiltrated immune cells were observed to participate in disrupting the homeostasis of esophageal epithelium to varying degrees. Conclusion The immune-correlated CXCR2 gene was proved to be a promising diagnostic indicator for EoE, and dysregulated regulatory T cells (Tregs)/neutrophils might play a crucial role in the pathogenesis of EoE in children.

Abstract
INTRODUCTION Eosinophilic gastrointestinal disorders beyond eosinophilic esophagitis (non-EoE EGIDs) are rare chronic inflammatory disorders of the gastrointestinal (GI) tract. Diagnosis is based on clinical symptoms and histologic findings of eosinophilic inflammation after exclusion of a secondary cause or systemic disease. Currently, no guidelines exist for the evaluation of non-EoE EGIDs. Therefore, the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) formed a task force group to provide consensus guidelines for childhood non-EoE EGIDs. METHODS The working group was composed of pediatric gastroenterologists, adult gastroenterologists, allergists/immunologists, and pathologists. An extensive electronic literature search of the MEDLINE, EMBASE, and Cochrane databases was conducted up to February 2022. General methodology was used in the formulation of recommendations according to the Appraisal of Guidelines for Research and Evaluation (AGREE) II and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to meet current standards of evidence assessment. RESULTS The guidelines provide information on the current concept of non-EoE EGIDs, disease pathogenesis, epidemiology, clinical manifestations, diagnostic and disease surveillance procedures, and current treatment options. Thirty-four statements based on available evidence and 41 recommendations based on expert opinion and best clinical practices were developed. CONCLUSION Non-EoE EGIDs literature is limited in scope and depth, making clear recommendations difficult. These consensus-based clinical practice guidelines are intended to assist clinicians caring for children affected by non-EoE EGIDs and to facilitate high-quality randomized controlled trials of various treatment modalities using standardized, uniform disease definitions.

Abstract
BACKGROUND Data on eosinophilic gastrointestinal disorders (EGIDs) are limited in the United Arab Emirates. OBJECTIVE This study aimed to describe the distribution of eosinophilic gastritis/gastroenteritis (EoG/EGE) and eosinophilic esophagitis (EoE) among patients whose data are recorded on the Cleveland Clinic Abu Dhabi (CCAD) systems. METHODS Anonymized aggregate data were obtained from the Clinerion Patient Network Explorer (PNEx®) network installed at the CCAD on patients diagnosed with EoG/EGE (n=17, of whom 11 (64.7%) were females) or with EoE (n=118, of whom 35 (29.7%) were females) between 2015 and 2022; 63 (53.4%) were diagnosed between 2020 and 2022. RESULTS The vast majority of EoE patients visited the gastroenterology clinic (111, 94.1%), followed by the primary care (70, 59.3%), the emergency medicine (60, 50.8%), and the immunology (59, 50%) units. A total of 84 patients with EoE also presented with another type-2 inflammatory condition including allergic rhinitis, food allergy, and atopic dermatitis. Proton pump inhibitors and corticosteroids were widely prescribed, and four patients with EoE have been commenced on biologics since 2020. However, heterogeneity of medication use was identified, warranting local clinical practice guidelines. CONCLUSION A referral network could be established with local and regional reach, which relies on a multidisciplinary approach for the management of EoE and associated type 2 co-morbidities. More studies are needed to better depict the clinical picture of patients with EGIDs in general and EoE, in particular, in terms of diagnosis, pharmacological treatment, non-medical interventions, disease course, and patient-reported outcomes.

Abstract
Eosinophilic duodenitis is an inflammation of the duodenum, characterized by an abundance of eosinophils, typically triggered by hypersensitivity reactions. Typically, recurrent abdominal pain with eosinophilic duodenitis is rare in individuals without a history of atopic conditions like asthma. Here, we present the case of a 62-year-old man who experienced recurrent upper abdominal pain for 12 months and unintended weight loss for the past six months. The patient reported no allergies to food, drugs, or the environment, and has no history of other atopic conditions. Esophagogastroduodenoscopy (EGD) with biopsy of the duodenum and stomach revealed 32 eosinophils per high-power field (HPF), which is mild. Skin prick testing yielded negative results. Following initial treatment with H2 inhibitors, proton pump inhibitors, and budesonide for a total of 12 weeks, the patient reported an improvement in symptoms and subsequent weight gain. This report emphasizes a rare case of eosinophilic duodenitis in a nonatopic individual with a successful treatment regimen. His quality of life improved with weight gain, resolved abdominal pain, and improved appetite. Although the patient's condition lasted about 12 months, our report showcased the importance of timely clinical diagnosis and appropriate combination therapy to alleviate progressive pain associated with eosinophilic duodenitis.

Abstract
BACKGROUND Eosinophilic gastritis (EoG) associates with type 2 immunity. However, the type 2 cytokine cellular source, gastric T-cell composition, and gastric T-cell relationship (or relationships) with disease pathology remain understudied. OBJECTIVE We defined gastric T-cell populations and their association with histologic and endoscopic EoG pathology. METHODS Gastric biopsy samples (n = 6 EoG, n = 7 control) were subjected to histologic, endoscopic, and flow cytometry analyses. In a complementary cohort (n = 83 EoG), IL4, IL5, and IL13 mRNA levels were correlated with EoG pathologic parameters. RESULTS Gastric biopsy samples contained CD3+ T cells that were mainly CD8+; the CD8/CD4 ratio was comparable in EoG and control biopsy samples (5.7 ± 3.0 and 4.3 ± 0.6, respectively; P = .28). Gastric regulatory T (CD3+CD4+FOXP3+) and TH2 (CD3+CD4+GATA3+) cell levels were increased in EoG versus controls (2-fold, P < .05 and 10-fold, P < .001, respectively) and correlated with gastric eosinophil levels (r = 0.63, P < .05 and r = 0.85, P < .001, respectively), endoscopic pathology (r = 0.56, P < .01; r = 0.84, P < .001, respectively), and histopathology (r = 0.72, P < .01; r = 0.82, P < .01, respectively). Cytokine-positive, most notably IL-4+, TH2 cell levels strongly correlated with histologic and endoscopic scores (r = 0.82, P < .0001 and r = 0.78, P < .0001, respectively). In an independent EoG cohort (n = 83), bulk gastric IL4, IL5, and IL13 mRNA levels correlated with histologic score (r = 0.22, P < .005; r = 0.54, P < .0001; and r = 0.36, P < .0001, respectively) and endoscopic score (r = 0.27, P < .001; r = 0.40, P < .0001; and r = 0.35, P < .0001, respectively). CONCLUSIONS EoG is a TH2 cell-associated disease featuring increased gastric type 2 cytokine-producing CD3+CD4+GATA3+TH2 cells that strongly correlate with disease pathologies.

Primary eosinophilic gastrointestinal disorders (EGID) are increasingly prevalent, immune‐mediated, chronic conditions which primarily affect pediatric and young adult patients, leading to substantial disease burden, and poor quality of life. EGID may either involve single portions of the gastrointestinal tract (i.e., esophagus, stomach, small bowel, and colon) or a combination. Their strong association with allergic disorders has been recently recognized, and although their shared pathophysiological basis remains partly elusive, this feature greatly impacts the diagnostic and treatment work‐up. We herein critically discuss the current knowledge on the association of EGID and allergic disorders, including atopic dermatitis, allergic rhinitis, allergic asthma, and food or drug allergy. In particular, we reviewed the literature focusing on their epidemiology, pathophysiological basis and mechanisms, and diagnostic strategies. Finally, we discuss the currently ongoing clinical trials targeting EGID and allergic diseases, including, among others the monoclonal antibodies dupilumab, mepolizumab, benralizumab, and lirentelimab.

Abstract
BACKGROUND To date, few studies have been conducted in Italy on pediatric eosinophilic gastrointestinal diseases (EGIDs). AIMS To assess clinical features of pediatric patients with EGIDs who are followed in a tertiary pediatric center. METHODS From January 2015 to December 2019, we retrospectively enrolled patients with EGIDs, and collected clinical, endoscopic, and histological data. RESULTS We enrolled 112 patients, 75.8% were male. Mean age was 9.3 ± 4.8 years. Diagnosis of EGIDs has increased in the last two years, with non-esophageal EGIDs more prevalent than eosinophilic esophagitis (EoE) (5.1% vs. 4.4%). Approximately 30% of patients had allergic comorbidities, which prevailed in children with EoE. Autism spectrum disorders were common in patients with non-esophageal EGIDs (p = 0.007), a statistically significant finding. In addition, esophageal atresia was associated with EoE (p = 0.04). Most EGIDs patients had normal findings or an inflammatory endoscopic phenotype. Patients with EoE were mainly treated with proton pump inhibitors (PPIs) alone or in combination with swallowed steroids. PPIs, oral steroids, and food-elimination diets were prescribed to patients with non-esophageal EGIDs. CONCLUSION This is the first Italian study revealing an increased frequency of EGIDs in a pediatric population. Further studies are needed to characterize patients with these emerging diseases.

Abstract
Functional dyspepsia (FD), a common disorder of gastrointestinal function, originated from the gastroduodenum. Although the therapeutic effect of acupuncture has been investigated by various high-quality randomized controlled trials, the potential mechanisms showed obvious heterogeneity. This review summarized the potential mechanisms of acupuncture on FD in order to guide for future laboratory and clinical studies. Here, we argued that the primary cause of FD was gastroduodenal low-grade inflammation and acid exposure, which impaired mucosal integrity, caused brain-gut axis dysfunction, and impaired brain network connectivity, all of which generated various symptom patterns. Overall the clinical studies indicated that acupuncture was a promising treatment to alleviate symptoms in FD patients, whose efficacy was influenced by acupoints and individual variance. Mechanistically, studies with animal models of FD and patients have shown that acupuncture, a non-invasive strategy for nerve stimulation, may have the potential to control intestinal inflammation and suppress acid-secretion via different somatic autonomic reflex pathways, regulate the brain-gut axis through intestinal microbiota, and has the potential to ameliorate FD-symptoms. The cumulative evidence demonstrated that acupuncture is a promising treatment to alleviate symptoms of FD patients.

Abstract
BACKGROUND Eosinophilic gastrointestinal disorders (EGIDs) include inflammatory conditions with enteric infiltration of eosinophils and resulting symptoms. This study aims to examine a population-based sample of patients for prevalence, mortality, and cancer risk in EGIDs distal to the esophagus. METHODS Nationwide, population-based cohort study. EGID was identified through relevant biopsy codes from Sweden's all 28 pathology departments through the ESPRESSO cohort. Individuals with EGID were then matched to general population reference individuals with similar age and sex. Study participants were linked to Swedish healthcare registers. Through Cox regression, we calculated adjusted hazard ratios (aHRs) adjusting for sex, age, county, calendar period, and education. RESULTS In total, 2429 patients (56% female) were found to have EGID distal to the esophagus, representing a prevalence of about 1/4800 in the Swedish population. Mean age was 44 years with 11% children at the time of diagnosis. Mortality was increased 17% in patients with EGIDs compared to reference individuals (aHR = 1.17; 95%CI = 1.04-1.33). Excess mortality was seen in gastric and small bowel eosinophilic disease, but not colonic disease (aHR = 1.81; 95%CI = 1.32-2.48, aHR = 1.50; 95%CI = 1.18-1.89, and aHR = 0.99; 95%CI = 0.85-1.16, respectively). Cause specific mortality was driven by cancer-related death (aHR = 1.33; 95%CI = 1.05-1.69). However, this study failed to show an increase in incident cancers (aHR = 1.14; 95%CI = 0.96-1.35). Comparison of EGID individuals with their siblings yielded similar aHRs. CONCLUSIONS This study found an increased risk of death in patients with EGIDs distal to the esophagus, with cancer death driving the increase. Proximal gut disease seems to confer the greatest risk. There was no increase in incident cancers.

Abstract
Introduction and importance Eosinophilic gastroenteritis (EG) is a rare disease, characterized by eosinophilic infiltration of different layers of intestinal wall. Thus having a wide spectrum of presentation leading to diagnostic dilemma. Case presentation We report a case of 55 years old female who presented with pain in abdomen, constipation, vomiting off and on with passage of stools on alternate days since 6 months. Plain radiographs showed radio-opaque densities in abdomen. Contrast enhanced computed tomography (CECT) of abdomen showed Ileal stricture with dilated proximal bowel loops with enteroliths. Exploratory laparotomy confirmed ileal stricture with thickening of the mesentery and an ileal diverticulum. Resection of ileal stricture was performed. The resected segment contained seven hard, black enteroliths. Histopathology of the resected specimen confirmed EG. Stone analysis showed dense faecal matter with bile salts. Clinical discussion EG leads to symptoms ranging from vomiting, abdominal pain, diarrhoea, blood loss in stools, anaemia to malabsorption resulting in diagnostic dilemma. It may cause gastrointestinal obstructive symptoms secondary to stricture, depending upon the predominant layer involved. Conclusion The differential diagnosis of EG should always be considered when dealing with gastroenteritis presenting with radio-opaque densities in abdomen. Eosinophilic Gastroenteritis (EG) is a rare disease with a wide spectrum of clinical presentation. Diagnosis of EG is often missed or delayed due to its overlapping findings with other GI disorders. Presentation of Eosinophilic Gastroenteritis with Enterolith is rare. Eosinophilic Gastroenteritis once diagnosed can be treated medically. However, once stricture or enteroliths are formed or there is intestinal obstruction, surgery is the mainstay of treatment.

Abstract
BACKGROUND A patient reported outcome (PRO) instrument with evidence of validity and reliability for assessing symptoms of eosinophilic gastritis (EG) and eosinophilic gastroenteritis (EGE) is needed to measure treatment benefit in clinical trials. The aim of this research is to develop an EG/EGE symptom PRO instrument for patients aged 12 and above. METHODS The Symptom Assessment for Gastrointestinal Eosinophilic Diseases (SAGED) was developed through a literature review, discussions with expert clinicians, and concept elicitation and cognitive debriefing interviews with patients. Patients (n = 28) were recruited based on confirmed diagnosis and self-reported symptoms. The final instrument was translated and linguistically validated with additional cognitive debriefing interviews (n = 105). RESULTS SAGED is a 24-h recall questionnaire consisting of eight items evaluating the core symptoms of EG and EGE (abdominal pain, nausea, bloating, early satiety, loss of appetite, vomiting, and diarrhea). Seven of the eight items are evaluated on an 11-point numerical rating scale ranging from 'none' to 'worst imaginable'. Cognitive debriefing interviews showed that adults and adolescents understand the content and are able to select a response that reflects their experience. The linguistic validation process produced 21 translations that are understandable to patients and conceptually equivalent to the source version. CONCLUSIONS SAGED is suitable for measuring symptom improvement in adult and adolescent patients with EG and/or EGE. The content validity of SAGED has been established through best practices in qualitative research for PRO instrument development. The psychometric properties of SAGED will be evaluated in a future study.

Abstract
Innate lymphoid cells (ILCs) are a group of innate immune cells, which constitute the first line of defense in the immune system, together with skin and mucous membrane. ILCs also play an important role in maintaining the homeostasis of the body, particularly in the complex and diverse environment of the intestine. ILCs respond to different microenvironments, maintaining homeostasis directly or indirectly through cytokines. As a result, ILCs, with complex and pleiotropic characteristics, are associated with many gastrointestinal diseases. Their ability of transition among those subgroups makes them function as both promoting and inhibiting cells, thus affecting homeostasis and disease progressing to either alleviation or deterioration. With these special characteristics, ILCs theoretically can be used in the new generation of immunotherapy as an alternative and supplement to current tumor therapy. Our review summarizes the characteristics of ILCs with respect to category, function, and the relationship with intestinal homeostasis and gastrointestinal diseases. In addition, potential tumor immunotherapies involving ILCs are also discussed to shed light on the perspectives of immunotherapy.

Abstract
Episodic angioedema with eosinophilia (EAE) (Gleich's syndrome) is a rare disease characterized by hypereosinophilia (up to 95 × 109 cells/L), recurrent episodes of angioedema, urticaria, weight gain, and fever, that occur at periodical intervals (usually every 3-4 weeks). The exact etiology of EAE is still unclear, but both eosinophils and abnormalities of cytokines homeostasis seem to play a pivotal role in the pathogenesis of the disease. In particular, the cyclic elevation of serum interleukin-5 before the increase in eosinophil count has been reported. Herein, we performed a broad literature review and report the case of a thirty-two-year-old woman with a two-year history of cyclic angioedema attacks, urticaria, periodic weight gain, and severe hypereosinophilia, diagnosed with EAE and treated with oral corticosteroids. Describing the most relevant clinical features of EAE reported so far in the literature, we aim to provide physicians with some useful tools to help them deal with this disease. In addition, we aim to raise awareness about this rare condition in which approved diagnostic classification criteria are currently missing.

Abstract
In daily practice, the presence of inflammation in gastric biopsies prompts a mental algorithm, an early question being whether the lesion present is Helicobacter-associated. If Helicobacter organisms are not found, then there is a further algorithm, governed by the predominant type of inflammatory cells present, and the presence of other features such as intraepithelial lymphocytosis, a subepithelial collagen band, granulomas, coexisting chronic inflammation, focality, and superimposed reactive changes including erosions and ulcers. Each of these generates its own differential diagnosis. If no inflammation is present, then the two major changes specifically looked for are the changes associated with hypergastrinaemia, by far the most common cause of which is treatment with proton pump inhibitors, and reactive changes. These may be present with and without accompanying inflammation, and, when the epithelial changes dominate, the term gastropathy is preferred. In this article, we present an approach to non-Helicobacter inflammation and gastropathies.

Abstract
Primary eosinophilic gastrointestinal disorders (EGIDs) are emerging chronic/remittent inflammatory diseases of unknown etiology, which may involve any part of the gastrointestinal (GI) tract, in the absence of secondary causes of GI eosinophilia. Eosinophilic esophagitis is the prototype of eosinophilic gastrointestinal disorders and is clinically characterized by symptoms related to esophageal inflammation and dysfunction. A few studies have assessed the nutritional status of patients with eosinophilic gastrointestinal disorders, showing conflicting results. This review summarizes the current evidence on the nutritional status of patients with EGIDs, focusing on the pediatric point of view and also speculating potential etiological mechanisms.

Abstract
Eosinophilic gastroenteritis is an inflammatory disease characterized by pathologic eosinophilic infiltration of any portion of the gastrointestinal tract. Depending on the involved site and layer of eosinophilic infiltration, symptoms and signs are heterogeneous. This manuscript reports two patients who presented with acute upper gastrointestinal tract bleeding and protein-losing enteropathy signs, and were diagnosed as having eosinophilic gastroenteritis. Upper endoscopy revealed an appearance of mucosal pseudomass in both patients. Both patients achieved satisfactory clinical improvement with an elimination diet and proton pump inhibitor treatment.

Abstract
Eosinophilic colitis (EoC) is a pathological entity associated with abnormal infiltration of colonic mucosa by eosinophilic polynuclear cells (Eo). This is a relatively common pathology in infants and children under 2 years old, but is more rare and has been less studied in adults. EoC can be classified as primary or secondary. Primary EoC is, in the majority of cases, related to an allergic reaction, either IgE-mediated and capable of causing an anaphylactic-type food allergy, or not mediated by IgE and capable of giving rise to food enteropathy. The symptoms for adults with EoC are variable and non-specific, diarrhoea and abdominal pain being the most common signs. There is no histological consensus for the diagnosis of EoC. The presence of over 40 Eo per high-power field (×400) in at least two different colonic segments could be suggested as the criterion for the diagnosis. In adults with primary EoC, skin tests are of limited value and the response to a restrictive diet is less effective than in young children, given that IgE or non-IgE-mediated allergic reactions are rarely identified and EoC generally require medical treatment. There is no consensus on the treatment of EoC, but the potential efficacy of corticosteroids and budesonide has been demonstrated in the vast majority of cases studied.

Abstract
BACKGROUND Primary eosinophilic gastrointestinal diseases (EGIDs) are increasingly described disorders that include eosinophilic esophagitis (EoE), eosinophilic gastritis, gastroenteritis, and colitis. The exact epidemiology of nonesophageal EGIDs (non-EoE EGIDs) is still unclear. OBJECTIVE To evaluate the epidemiology of non-EoE EGIDs in adults and children referred to outpatient clinics for gastrointestinal symptoms. METHODS We conducted a systematic review and meta-analysis using a protocol registered and published with the international prospective register of systematic reviews (PROSPERO CRD42018111437). We searched PubMed, EMBASE, Web of Science, Scopus, and CINAHL for cohort or cross-sectional studies published since 1990, evaluating the incidence and prevalence of non-EoE EGIDs. We assessed study quality and risk of bias using items derived from the Strengthening the Reporting of Observational Studies in Epidemiology statement. RESULTS A total of 576 articles were identified. Ten studies with 13,377 participants were included in the analysis, with the results showing high heterogeneity. No significant publication bias was found. The overall prevalence of non-EoE EGIDs in patients with gastrointestinal symptoms was 1.9% (95% confidence interval: 0.575-3.894; I2 = 92.72%; P < .001). Because none of the examined studies were prospectively designed, incidence rates could not be determined. CONCLUSIONS More prospective, large-scale, multicenter studies are needed to evaluate reported data and to further investigate the epidemiology of non-EoE EGIDs and their possible risk factors and comorbidities.

Abstract
Eosinophilic disorders of the gastrointestinal tract (EGID) are a group of diseases characterized by an eosinophilic inflammation limited to the GI tract. EoE is by far the most common EGID and is an atopic chronic/relapsing eosinophilic inflammation of the esophagus. It is now recognized as an increasingly common cause of esophageal dysfunction, fibrosis, stricture, and food impaction in children and adults. There are globally accepted guidelines for its treatment that are based on the use of proton pump inhibitors (PPI), corticosteroids, and diet. Many clinical trials have been published on the use of biologics in this disease. Non-EoE-EGID is a rare, more severe disease. No globally accepted guidelines exist for their treatment and diagnosis. Corticosteroids are at the moment the most effective treatment of those diseases.

Abstract
Primary eosinophilic gastrointestinal diseases (EGIDs) represent a heterogeneous group of disorders characterized by eosinophilic inflammation in the absence of known causes for eosinophilia, selectively affecting different segments of the gastrointestinal tract. While pediatric eosinophilic esophagitis (EoE) is a well-defined disease with established guidelines, Eosinophilic Gastritis (EoG), Eosinophilic Gastroenteritis (EoGE) and Eosinophilic Colitis (EoC) remain a clinical enigma with evidence based on limited anecdotal case reports. Large cross-sectional studies in the US defined a prevalence of EoG and EoGE ranging from 1,5 to 6,4/100.000 and from 2,7 to 8,3/100.000 subjects respectively, while the prevalence of EoC ranges from 1,7 to 3,5/100.000 subjects. Regarding the pathogenesis, it is hypothesized that EGIDs result from the interplay between genetic predisposition, intestinal dysbiosis and environmental triggers. Clinically, EGIDs might present with different and nonspecific gastrointestinal symptoms depending on the involved intestinal tract and the extension of eosinophilic inflammatory infiltrate. The diagnosis of EGIDs requires: 1. recurrent gastrointestinal symptoms, 2. increased eosinophils for high power field in biopsy specimens, 3. absence of secondary causes of gastrointestinal eosinophilia. No validated guidelines are available on the clinical management of patients with EGIDs. Evidence from case reports and small uncontrolled case series suggests the use of dietary and corticosteroids as the first-line treatments. Considering the clinical follow-up of EGIDs, three different patterns of disease course are identified: single flare, recurring course-disease and chronic course-disease. This review will focus on pediatric EGIDs distal to esophagus, including Eosinophilic Gastritis (EoG), Eosinophilic Gastroenteritis (EoGE) and Eosinophilic Colitis (EoC).

Abstract
BACKGROUND The effectiveness of budesonide (BUD), a locally active steroid, on eosinophilic gastroenteritis (EGE) is not well understood. This study is to retrospectively evaluate the efficacy of BUD in children with EGE. METHODS Forty-four children, diagnosed with EGE, were enrolled from 2013 to 2017 in our center. According to patients' preference, all the patients were treated with dietary elimination (DE) and montelukast therapy, or combined with prednisone (PRED)/BUD. Patients' clinical manifestations, treatments, and outcomes were reviewed from the medical records. Twenty-four patients (7 PRED, 7 BUD, 10 DE) received therapy for ≥8 weeks, followed by repeat endoscopy and biopsies. Histological response was defined as <20 eos/hpf (eosinophils per high-power field). RESULTS Significant number of patients in DE+PRED (6/7, 85.7%) and DE+BUD (6/7, 85.7%) groups achieved histological response than in the DE group (3/10.30%) (p = 0.024). Mean post-treatment peak eos/hpf in the DE+PRED group was 16.57 ± 6.85 vs. 10.00 ± 5.07 in the DE+BUD group vs. 36.60 ± 24.57 in the DE group (p = 0.009). Change of eos/hpf from pre- to post-treatment was -49.86 ± 45.02 vs. -34.29 ± 23.44 in the BUD group vs. -0.3 ± 23.95 in the DE group (p = 0.011). There were no significant differences between DE+PRED and DE+BUD groups (p = 0.470, p = 0.363, respectively). CONCLUSION BUD is effective in the treatment of EGE and has similar effectiveness with PRED.

Abstract
BACKGROUND Eosinophilic gastroenteritis (EoGE) can be diagnosed on the basis of histologic criteria; however, the pathology is considered to be heterogeneous. There is no consensus on the management of this enigmatic disorder with an unknown etiology. PATIENTS AND METHODS Data for patients diagnosed with EoGE and followed up over a 1-year period were analyzed. Their symptoms, patterns of flares, and type of treatment were documented. The shift in peripheral blood eosinophil levels was also examined. RESULTS A total of 10 (mean age, 44 years; range: 31-70 years; women, 5) patients were diagnosed with EoGE. The most frequent presenting symptom was abdominal pain, and eight patients were classified with mucosal type of EoGE. Chronic disease or multiple flares were observed in seven out of 10 (70.0%) patients, and all of them had a history of allergy. Four were corticosteroid dependent (three relapsed during corticosteroid tapering and one following corticosteroid withdrawal). One of them received anti-IL5 monoclonal antibody that enabled corticosteroid dose tapering. In four patients with highly elevated initial eosinophil levels at diagnosis, the peripheral eosinophil level correlated with the amelioration and deterioration of their symptoms. The remaining three patients had a single flare without relapse. Two had no history of allergy. CONCLUSION EoGE is a unique disorder with a variable clinical course. Although further studies are required to confirm our observations, the presence of other allergic disorders is associated with chronicity or multiple flares. Peripheral eosinophil level may be an effective biomarker for recurrence in patients with severe systemic disorders at diagnosis.

Abstract
AIM To analyze the clinical features, diagnosis, and prognosis of eosinophilic gastroenteritis (EG).
METHODS A retrospective analysis was performed of clinical data of 88 cases with EG at our hospital between June 2013 and August 2018.
RESULTS Eighty-eight patients were included, with a male to female ratio of 1.2:1. The patients ranged in age from 14 to 73 years, with a mean age 45.1 years. Abdominal pain was the most common symptom, 73.3% of patients had positive allergen screening results, and some patients had negative endoscopic findings. Common endoscopic abnormalities were mainly congestion, erosion, ulcers, polyps and so on, and pathological examination revealed a large number of eosinophils infiltrated in the gastrointestinal tract, with the highest average value detected in the cecum. Treatment with proton pump inhibitors was effective. Glucocorticoid therapy was useful, but the disease could recur.
CONCLUSION The pathogenesis of EG is still unclear, although it is known that allergens play an important role in it. The clinical manifestations are atypical. An increase of eosinophilic granulocytes in peripheral blood and bone marrow smear can support the diagnosis. Imaging and endoscopic manifestations are not specific. Pathology is the key to diagnosis. Glucocorticoid therapy can obtain good results, but there have been no unified criteria on the specific dosage and course of treatment .

Abstract
Background Up to one-third of the patients suffering from eosinophilic esophagitis (EoE) present a refractory form, as defined by nonresponsiveness in clinical, endoscopic, or histological assessment after first-line therapy. Several studies recently investigated which factors can influence the development of this disease, but very few analyzed the factors underlying refractory EoE. Methods Medical charts of patients affected by EoE were retrospectively evaluated. Phenotyping of patients was conducted according to demographic, clinical, histological, and treatment variables. Then, patients were divided into responder and nonresponder to therapy and distinguished among children and adults. Results Forty-five children and 35 adult EoE patients were included. In the pediatric population, female sex (p < 0.05) and a higher score of visual analogue scale (VAS) at the follow-up visit (p = 0.02) were significantly associated to the risk of refractory EoE. Among adults, statistical significance was reached for years of follow-up (p = 0.001), diagnostic delay (p = 0.03), use of antibiotics during infancy (p = 0.01), and food allergy (p = 0.04). Conclusions Our study highlighted female sex and a higher VAS score at the time of follow-up visits as risk factors for refractory EoE in children, while the risk factors in adults were identified as fewer years of follow-up, greater diagnostic delay, use of antibiotics during infancy, and food allergy.

Abstract
AIM This study assessed the prevalence, clinical presentation and outcome of lymphocytic colitis (LC) and eosinophilic gastrointestinal disease (EGID) in children with severe, recurrent abdominal pain (RAP), by describing the predominant symptoms, diagnostic approaches and treatment options. METHODS We performed a retrospective follow-up study at a Danish regional hospital by reviewing the histology reports of the children who had undergone gastrointestinal endoscopy for RAP. Data were retrieved from the medical records of those who met the diagnostic criteria for LC and, or, EGID from 2011 to 2016. The study population comprised 381 patients who underwent a diagnostic process to clarify RAP. RESULTS A total of 74 patients (39 females) aged 2-17 years, with severe RAP as the most predominant symptom underwent gastrointestinal endoscopy. This identified 16/74 (21.6%) with LC (n = 6) and, or, EGID (n = 11), which equated to 4.2% with RAP. No biochemical patterns of abnormalities were found. Medical treatment and, or, diet generally induced and maintained clinical remission. CONCLUSION We found 16 children with LC and, or, EGID. The predominant symptom was severe RAP. All patients had a macroscopically normal mucosa at endoscopy, a specific histopathological feature and no characteristic biochemical findings. Endoscopy should be considered in these cases.

Abstract
BACKGROUND Accurate identification of eosinophils in the gastrointestinal (GI) tract of dogs with eosinophilic GI disease (EGID) by histological evaluation is challenging. The currently used hematoxylin and eosin (H&E) staining method detects intact eosinophils but does not detect degranulated eosinophils, thus potentially underrepresenting the number of infiltrating eosinophils. OBJECTIVE To develop a more sensitive method for identifying and quantifying both intact and degranulated eosinophils to diagnose EGID more accurately. METHODS Endoscopically obtained paraffin-embedded intestinal biopsy specimens from dogs with GI signs were examined. The study groups were dogs with eosinophilic enteritis (EE), lymphoplasmacytic and mixed enteritis, and control dogs with GI signs but no histologic changes on tissue sections. Consecutive sections were immunolabeled with monoclonal antibodies (mAbs) against the eosinophil granule protein eosinophil peroxidase (Epx) and stained by H&E, respectively. The number of eosinophils was manually quantified and classified as intact or degranulated. RESULTS The number of intact eosinophils detected in Epx mAb-labeled duodenal sections was significantly higher compared with that in H&E-stained sections, with a similar relationship noted in the colon and stomach. The Epx mAb allowed the unique assessment of eosinophil degranulation. The number of intact and degranulated eosinophils was significantly higher in duodenal lamina propria of the EE and mixed group compared to the control group. CONCLUSION Immunohistochemical detection of Epx provides a more precise method to detect GI tract eosinophils compared to H&E staining and could be used as an alternative and reliable diagnostic tool for assessment of biopsy tissues from dogs with EGID.

Abstract
The Consortium of Eosinophilic Gastrointestinal Diseases and the International Gastrointestinal Eosinophil Researchers organized a day-long symposium at the recent 2018 Annual Meeting of the American Academy of Allergy, Asthma & Immunology, which was coupled for the first time with the World Allergy Organization meeting to create an international platform. The symposium featured experts in many facets of eosinophilic gastrointestinal diseases, including allergy, immunology, gastroenterology, pathology, and nutrition, and was a well-attended event. The basic science, genetics, cellular immunology, and clinical features of the diseases, with a focus on epithelial, eosinophil, and mast cell responses, as well as current and emerging treatment options, were reviewed. Here we briefly review some of the highlights of the material presented at the meeting.

Egan M, Furuta GT. Eosinophilic gastrointestinal diseases beyond eosinophilic esophagitis. Ann Allergy Asthma Immunol 2018; 121:162-167. [PMID: 29940308 DOI: 10.1016/j.anai.2018.06.013] [Citation(s) in RCA: 50] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2018] [Revised: 05/29/2018] [Accepted: 06/14/2018] [Indexed: 12/26/2022]
Abstract
OBJECTIVE Eosinophilic gastrointestinal diseases (EGIDs) are a rare group of disorders that can have varied clinical presentations dependent on the involved segment within the gastrointestinal tract. Eosinophilic gastritis presents with abdominal pain or vomiting, eosinophilic gastroenteritis presents with diarrhea and anemia or hypoalbuminemia, and eosinophilic colitis can present with diarrhea or bloody stools. These nonspecific symptoms remain poorly understood in their relation to the underlying pathogenesis, but a significant percentage of patients have atopy. In this review, we discuss the current literature on EGIDs to promote a practical approach to diagnosis and care. DATA SOURCES Review of published literature. STUDY SELECTIONS Clinically relevant literature from 1900 through 2018 was obtained from a PubMed search. Those that addressed prevalence, diagnosis, clinical manifestations, natural history, and treatment of EGIDs were reviewed and are summarized in this article. RESULTS Of the 485 articles found in the search, most of which were case reports, 71 were selected for review. The natural history of EGIDs is based primarily on case series and small numbers of patients, making therapeutic decisions difficult. Treatment remains limited to dietary restriction that is not effective in many patients and topical or systemic corticosteroids whose long-term use is to be avoided if possible. CONCLUSION With the seeming increase in all types of EGIDs, phenotypic descriptions are emerging that will likely promote better understanding of the pathogenesis and identification of novel therapeutic targets.

Abstract
The prevalence of reactive nasal inflammatory conditions, for example, allergic rhinitis and chronic rhinosinusitis, is steadily increasing in parallel with significant environmental changes worldwide. Allergens and as yet undefined environmental agents may trigger these conditions via the involvement of host intrinsic factors, including the innate and adaptive immune system, the nasal epithelium, and the nasal nervous system. The critical role of the nasal microbiota in coordinating these components has emerged in recent studies documenting a significant association between microbial composition and the onset and progression of allergic or nonallergic inflammation. It is now clear that the local microbiota is a major player in the development of the mucosa-associated lymphoid tissue and in the regulation of such adaptive responses as IgA production and the function of effector and regulatory T cells. Microbial components also play a major role in the regulation of epithelial barrier functions, including mucus production and the control of paracellular transport across tight junctions. Bacterial components, including lipopolysaccharide, have also been shown to induce or amplify neuroinflammatory responses by engaging specific nociceptors. Finally, bacterial products may promote tissue remodeling processes, including nasal polyp formation, by interacting with formyl peptide receptors and inducing the expression of angiogenic factors and matrix-degrading enzymes.

Abstract
Immune-mediated disorders affecting the gastrointestinal (GI) tract may compromise GI integrity, interfere with the absorption of nutrients and cause bleeding and inflammation. All these features contribute to the pathogenesis of anaemia, the most prevalent extra-intestinal manifestation of immune-mediated GI disorders. Anaemia is most commonly due to iron deficiency and/or inflammation, but vitamin deficiencies and, more infrequently, autoimmune haemolysis or drug-induced myelosuppression can be involved. Here we address several issues related to the differential diagnosis and treatment of anaemia in immune-mediated GI disorders, giving particular relevance to the problem of iron deficiency anaemia associated with inflammation. It is emphasized how, in most cases, anaemias due to iron or vitamin deficiencies are best treated by parenteral administration of the deficient factor(s), and how the available high dose intravenous (IV) iron formulations can reduce ambulatory and social costs of IV iron supplementation, while improving patient's compliance to treatment. Actual and future treatment possibilities for anaemia of inflammation, involving the use of erythropoiesis stimulating agents, biologicals and hepcidin inhibitors are discussed.

Abstract
Background Eosinophilic gastroenteropathy is an uncommon condition whose causes can be numerous and non-specific. The aim of the study was to characterize the presence of gastrointestinal disorders in the adult Maltese population and assess the degree of association with atopic diseases. Methods Adult patients with gastrointestinal eosinophilia in the gastrointestinal tract on histology were identified and their clinical case notes were reviewed. Patients were interviewed and asked questions regarding asthma, allergic rhinitis, and eczema. Results Sixty-six patients (39 female) were recruited. The most common clinical symptoms were diarrhea (42.4%) and abdominal pain (33.3%). The sites involved were stomach (10.6%), colon (56.1%), small bowel (10.6%), small bowel and colon (18.2%), esophagus (1.5%), and esophagus and colon (1.5%). Forty percent had persistent lower gastrointestinal symptoms and a repeat ileocolonoscopy was performed within 12 months. These patients were diagnosed with ulcerative colitis (n=10; 47.6%), Crohn's disease (n=6; 28.6%), indeterminate colitis (n=1; 4.8%) or microscopic colitis (n=4; 19%). Allergic rhinitis was present in 39.4% of the study group, eczema in 26.1%, and asthma in 19.7%. These findings were compared with local data for atopic conditions and the study group was found to have a significantly higher prevalence of allergic rhinitis (P=0.002), but not of asthma (P=0.62) or eczema (P=0.19). Conclusions A high proportion of patients with eosinophilic gastrointestinal infiltration were subsequently diagnosed with inflammatory bowel disease. Patients persistently symptomatic or who do not respond to treatment should be reassessed to exclude inflammatory bowel disease, given its high prevalence in this group of patients.

Abstract
BACKGROUND Diagnostic evaluation of eosinophilic esophagitis (EoE) remains difficult, particularly the assessment of the patient's allergic status. OBJECTIVE This study sought to establish an automated medical algorithm to assist in the evaluation of EoE. METHODS Machine learning techniques were used to establish a diagnostic probability score for EoE, p(EoE), based on esophageal mRNA transcript patterns from biopsies of patients with EoE, gastroesophageal reflux disease and controls. Dimensionality reduction in the training set established weighted factors, which were confirmed by immunohistochemistry. Following weighted factor analysis, p(EoE) was determined by random forest classification. Accuracy was tested in an external test set, and predictive power was assessed with equivocal patients. Esophageal IgE production was quantified with epsilon germ line (IGHE) transcripts and correlated with serum IgE and the Th2-type mRNA profile to establish an IGHE score for tissue allergy. RESULTS In the primary analysis, a 3-class statistical model generated a p(EoE) score based on common characteristics of the inflammatory EoE profile. A p(EoE) ≥ 25 successfully identified EoE with high accuracy (sensitivity: 90.9%, specificity: 93.2%, area under the curve: 0.985) and improved diagnosis of equivocal cases by 84.6%. The p(EoE) changed in response to therapy. A secondary analysis loop in EoE patients defined an IGHE score of ≥37.5 for a patient subpopulation with increased esophageal allergic inflammation. CONCLUSIONS The development of intelligent data analysis from a machine learning perspective provides exciting opportunities to improve diagnostic precision and improve patient care in EoE. The p(EoE) and the IGHE score are steps toward the development of decision trees to define EoE subpopulations and, consequently, will facilitate individualized therapy.

Inhibition of soluble epoxide hydrolase attenuates eosinophil recruitment and food allergen-induced gastrointestinal inflammation. J Leukoc Biol 2018; 104:109-122.

Abstract
Prevalence of food allergies in the United States is on the rise. Eosinophils are recruited to the intestinal mucosa in substantial numbers in food allergen-driven gastrointestinal (GI) inflammation. Soluble epoxide hydrolase (sEH) is known to play a pro-inflammatory role during inflammation by metabolizing anti-inflammatory epoxyeicosatrienoic acids (EETs) to pro-inflammatory diols. We investigated the role of sEH in a murine model of food allergy and evaluated the potential therapeutic effect of a highly selective sEH inhibitor (trans-4-{4-[3-(4-trifluoromethoxyphenyl)-ureido]-cyclohexyloxy}-benzoic acid [t-TUCB]). Oral exposure of mice on a soy-free diet to soy protein isolate (SPI) induced expression of intestinal sEH, increased circulating total and antigen-specific IgE levels, and caused significant weight loss. Administration of t-TUCB to SPI-challenged mice inhibited IgE levels and prevented SPI-induced weight loss. Additionally, SPI-induced GI inflammation characterized by increased recruitment of eosinophils and mast cells, elevated eotaxin 1 levels, mucus hypersecretion, and decreased epithelial junction protein expression. In t-TUCB-treated mice, eosinophilia, mast cell recruitment, and mucus secretion were significantly lower than in untreated mice and SPI-induced loss of junction protein expression was prevented to variable levels. sEH expression in eosinophils was induced by inflammatory mediators TNF-α and eotaxin-1. Treatment of eosinophils with t-TUCB significantly inhibited eosinophil migration, an effect that was mirrored by treatment with 11,12-EET, by inhibiting intracellular signaling events such as ERK (1/2) activation and eotaxin-1-induced calcium flux. These studies suggest that sEH induced by soy proteins promotes allergic responses and GI inflammation including eosinophilia and that inhibition of sEH can attenuate these responses.

Abstract
Gastric biopsies are routinely obtained from patients with symptoms related to the gastrointestinal tract and, as a result, a variety of histologic changes are observed in patients with or without endoscopic evidence of mucosal injury. Although Helicobacter pylori-related gastritis is still common, several other patterns of mucosal injury are increasingly encountered. These patterns of injury are classified based on the nature and distribution of inflammation, location of epithelial cell injury, presence of crystal or pigment deposition, and/or other unique features. This article discusses each of these patterns and provides a differential diagnosis for each.

Abstract
In the last decade, the full picture of the role of innate lymphoid cells (ILCs) has been gradually revealed. ILCs are classified into 3 groups based on their transcription factors and cytokine production patterns, which mirror helper T-cell subsets. Unlike T cells and B cells, ILCs do not have antigen receptors. They promptly respond to multiple tissue-derived factors, such as cytokines and alarmins, and produce multiple proinflammatory and immunoregulatory cytokines. It has been reported that ILC-derived cytokines are important for the induction and regulation of inflammation. Accumulating evidence suggests that ILCs play substantial roles in protection against infection and the pathogenesis of inflammatory diseases, such as allergic diseases and autoimmune diseases. Different ILC subsets localize in distinct tissue/organ niches and receive tissue-derived signals on different types of inflammation, which allows them to acquire diverse phenotypes with specialized effector capacities. In this review we highlight the roles of ILCs in a variety of organs, such as the airway, skin, and gastrointestinal tract, in the context of allergic and nonallergic inflammation.

Abstract
AIM To analyze the clinical characteristics of eosinophilic gastroenteritis (EGE) and to investigate the situations of missed diagnosis of EGE.
METHODS First, the clinical characteristics of 20 EGE patients who were treated at our hospital were retrospectively summarized. Second, 159 patients who underwent gastroscopy and 211 patients who underwent colonoscopy were enrolled. The pathological diagnosis showed only chronic inflammation in their medical records. The biopsy slides of these patients were reevaluated to determine the number of infiltrating eosinophils in order to assess the probability of a missed diagnosis of EGE. Finally, 122 patients who experienced refractory upper gastrointestinal symptoms for at least one month were recruited. At least 6 biopsy specimens were obtained by gastroscopy, and the number of eosinophils that had infiltrated was evaluated. Those who met the pathological diagnostic criteria of EGE underwent further examination to confirm the diagnosis of EGE. The probability of a missed diagnosis of EGE was prospectively investigated.
RESULTS Among the 20 patients with EGE, mucosal EGE was found in 15 patients, muscular EGE was found in 3 patients and serosal EGE was found in 2 patients. Abdominal pain was the most common symptom. The number of peripheral blood eosinophils was elevated in all 20 patients, all of whom were sensitive to corticosteroids. Second, among the 159 patients who underwent gastroscopy, 7 (4.40%) patients met the criteria for pathological EGE (eosinophil count ≥ 25/HPF). Among the 211 patients who underwent colonoscopy, 9 (4.27%) patients met the criteria for pathological EGE (eosinophil count ≥ 30/HPF). No patients with eosinophil infiltration were diagnosed with EGE in clinical practice before or after endoscopy. Although these patients did not undergo further examination to exclude other diseases that can also lead to gastrointestinal eosinophil infiltration, these might be the cases where the diagnosis of EGE was missed. Finally, among the 122 patients with refractory upper gastrointestinal symptoms, eosinophil infiltration was seen in 7 patients (5.74%). The diagnosis of EGE was confirmed in all 7 patients after the exclusion of other diseases that can also lead to gastrointestinal eosinophil infiltration. A positive correlation was observed between the duration of the symptoms and the risk of EGE (r = 0.18, P < 0.01). The patients whose symptoms persisted longer than 6 mo more readily developed EGE. None of the patients were considered to have EGE by their physicians before endoscopy.
CONCLUSION Although EGE is a rare inflammatory disorder, it is easily misdiagnosed. When a long history of abdominal symptoms fails to improve after conventional therapy, EGE should be considered.

Abstract
Food allergy develops as a consequence of a failure in oral tolerance, which is a default immune response by the gut-associated lymphoid tissues to ingested antigens that is modified by the gut microbiota. Food allergy is classified on the basis of the involvement of IgE antibodies in allergic pathophysiology, either as classic IgE, mixed pathophysiology or non-IgE-mediated food allergy. Gastrointestinal manifestations of food allergy include emesis, nausea, diarrhoea, abdominal pain, dysphagia, food impaction, protein-losing enteropathy and failure to thrive. Childhood food allergy has a generally favourable prognosis, whereas natural history in adults is not as well known. Elimination of the offending foods from the diet is the current standard of care; however, future therapies focus on gradual reintroduction of foods via oral, sublingual or epicutaneous food immunotherapy. Vaccines, modified hypoallergenic foods and modification of the gut microbiota represent additional approaches to treatment of food allergy.

Abstract
Eosinophilic gastroenteritis is a rare condition characterized by eosinophilic inflammation in the gastrointestinal tract resulting in a variety of gastrointestinal symptoms. There is currently a dearth of information on this topic in the pediatric literature, as very few cases have been reported. In this report, we present a case of eosinophilic gastroenteritis in a 10-week-old patient with initial presenting symptom of hematemesis. To our knowledge, this is the youngest case reported in the literature and is unique in its initial presentation.

Eosinophilic diseases of the gastrointestinal tract, including eosinophilic esophagitis (EoE) and eosinophilic gastroenteritis (EGE), are rare chronic pathologies of the digestive system, with an immuno-mediated pathogenesis. Recent data suggest that, together with the “classic” IgE-response to allergens, also a delayed hypersensitivity mechanism could be involved in the development of eosinophilic disorders. EoE and EGE were studied only in the latest decades and as a consequence accurate data are not yet available, concerning not only pathogenesis, but also epidemiology, treatment and outcomes. The diagnosis of EoE is centered on endoscopic findings but the certainty is obtained by histological examination from biopsy samples, that has a sensitivity of 100% when based on five samples. The currently available treatments include topical corticosteroids, specific diets and endoscopic treatment. Concerning EGE, three subtypes (mucosal, muscular, and serosal) were identified. The diagnosis is based, as for EoE, on endoscopic and histological assessment, and the treatment includes pharmacological and dietetic approaches. Further studies are warranted in order to better define the etiology and pathogenesis of eosinophilic diseases of the gastrointestinal tract, and thus to develop more appropriate and specific therapies.
