Abstract
INTRODUCTION Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus characterized by symptoms of esophageal dysfunction and histologically by predominantly eosinophilic infiltration of the squamous epithelium. European Society for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) published a guideline in 2014; however, the rapid evolution of knowledge about pathophysiology, diagnostic criteria, and therapeutic options have made an update necessary. METHODS A consensus group of pediatric gastroenterologists from the ESPGHAN Working Group on Eosinophilic Gastrointestinal Diseases (ESPGHAN EGID WG) reviewed the recent literature and proposed statements and recommendations on 28 relevant questions about EoE. A comprehensive electronic literature search was performed in MEDLINE, EMBASE, and Cochrane databases from 2014 to 2022. The Grading of Recommendations Assessment, Development and Evaluation system was used to assess the quality of evidence and formulate recommendations. RESULTS A total of 52 statements based on the available evidence and 44 consensus-based recommendations are available. A revision of the diagnostic protocol, options for initial drug treatment, and the new concept of simplified empiric elimination diets are now available. Biologics are becoming a part of the potential armamentarium for refractory EoE, and systemic steroids may be considered as the initial treatment for esophageal strictures before esophageal dilation. The importance and assessment of quality of life and a planned transition to adult medical care are new areas addressed in this guideline. CONCLUSION Research in recent years has led to a better understanding of childhood EoE. This guideline incorporates the new findings and provides a practical guide for clinicians treating children diagnosed with EoE.

Abstract
Eosinophilic esophagitis (EoE) is a chronic type 2-mediated inflammatory disease of the esophagus that represents the most common eosinophilic gastrointestinal disease. Experts in the field of EoE across Italy (i.e., EoETALY Consensus Group) including gastroenterologists, endoscopists, allergologists/immunologists, and paediatricians conducted a Delphi process to develop updated consensus statements for the management of patients with EoE and update the previous position paper of the Italian Society of Gastroenterology (SIGE) in light of recent evidence. Grading of the strength and quality of the evidence of the recommendations was performed using accepted GRADE criteria. The guideline is divided in two documents: Part 1 includes three chapters, namely 1) definition, epidemiology, and pathogenesis; 2) clinical presentation and natural history, and 3) diagnosis, while Part 2 includes two chapters: 4) treatment and 5) monitoring and follow-up. This document has received the endorsement of three Italian national societies including the SIGE, the Italian Society of Neurogastroenterology and Motility (SINGEM), and the Italian Society of Allergology, Asthma, and Clinical Immunology (SIAAIC). With regards to patients' involvement, these guidelines involved the contribution of members of ESEO Italia, the Italian Association of Families Against EoE.

Abstract
Endoscopic evaluation with biopsies is a mainstay of the diagnosis of eosinophilic esophagitis (EoE) and non-EoE eosinophilic gastrointestinal diseases (EGIDs). Increasing knowledge has resulted in the development of 2 standardized scoring systems: the Endoscopic REFerence Score (EREFS) for EoE and the EG-REFS for eosinophilic gastritis, although the latter has not been validated. In EGIDs, diagnosis and follow-up focus on eosinophil infiltration in biopsies. In this article, we will discuss the most commonly used endoscopic scores in EoE and non-EoE EGIDs, their validity for the diagnosis and follow-up of disease activity, as well as endoscopic interventions and areas of uncertainty.

Abstract
BACKGROUND Eosinophilic gastrointestinal diseases (EGIDs) are chronic, immune-mediated disorders characterised clinically by gastrointestinal symptoms and histologically by a pathologic increase in eosinophil-predominant inflammation in the gastrointestinal tract, in the absence of secondary causes of eosinophilia. AIMS To highlight emerging insights and research efforts into the epidemiology, pathophysiology, diagnostic and therapeutic aspects of eosinophilic oesophagitis (EoE) and non-EoE EGIDs, and discuss key remaining knowledge gaps. METHODS We selected and reviewed original research, retrospective studies, case series, randomised controlled trials, and meta-analyses. RESULTS Standardised nomenclature classifies EGIDs as EoE, eosinophilic gastritis (EoG), eosinophilic enteritis (EoN), and eosinophilic colitis (EoC). Incidence and prevalence of EoE are rising, emphasising the need to better understand how environmental risk factors and genetic features interact. Advances in understanding EoE pathophysiology have led to clinical trials of targeted therapy and the approval (in the United States) of dupilumab for EoE. Several therapies that are under investigation hope to satisfy both histologic and clinical targets. For non-EoE EGIDs, efforts are focused on better defining clinical and histopathologic disease determinants and natural history, as well as establishing new therapies. CONCLUSIONS Unmet needs for research are dramatically different for EoE and non-EoE EGIDs. In EoE, non-invasive diagnostic tests, clinicopathologic models that determine the risk of disease progression and therapeutic failure, and novel biologic therapies are emerging. In contrast, in non-EoE EGIDs, epidemiologic trends, diagnostic histopathologic thresholds, and natural history models are still developing for these more rare disorders.

Abstract
INTRODUCTION Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus with increasing prevalence worldwide. It is a multifactorial disease caused by a combination of immunologic, genetic, and environmental factors. The clinical presentation of EoE varies largely, especially between different age groups. While diagnostic criteria and therapeutic goals are similar in children and adults, there are differences in treatment, with a more cautious approach in children to avoid growth disturbances. In addition, close monitoring and follow-up are essential in children to ensure uninterrupted growth. AREAS COVERED A search in PubMed/MEDLINE, EMBASE, and SCOPUS databases was conducted to identify relevant studies published between January 2010 and January 2023 to give an overview of the state-of-the-art of EoE epidemiology, diagnosis, and treatment while focusing on similarities and differences between the adult and the pediatric population. EXPERT OPINION The current state of research indicates that while significant progress has been made in understanding and treating EoE, further research and advances are needed to optimize diagnostic strategies, tailored treatment approaches, monitoring, and follow-up, and improve long-term outcomes for patients. With further innovation, the management of EoE can become more precise and tailored, leading to better patient outcomes and improved quality of life.

Abstract
Eosinophilic esophagitis (EoE) is an immune-mediated disease that manifests with dysphagia and is characterized by the predominantly eosinophilic infiltration of the esophageal mucosa. Several instruments have been developed to assess the symptoms of EoE: the Daily Symptom Questionnaire (DSQ), EoE Activity Index (EEsAI), Pediatric EoE Symptom Severity (PEESSv2), etc. The use of the EREFS is a gold standard for endoscopic diagnosis. The EoE histologic scoring system (EoEHSS) was elaborated for the assessment of histological features in EoE. However, the remission criteria are not clearly defined and vary greatly in different studies. Gastroenterologists establish the severity of EoE mainly based on endoscopic findings. At the same time, EoE requires a multidisciplinary approach. The recently developed Index of Severity of Eosinophilic Esophagitis (I-SEE) that is built on symptoms, endoscopic findings, and histological features is promising.

Abstract
BACKGROUND The eosinophilic esophagitis histologic scoring system (EoEHSS) was developed to enhance the diagnostic standard of peak eosinophil count (PEC) in evaluating disease activity in EoE. AIMS (1) Correlate the EoEHSS and PEC to measures of symptomatic and endoscopic disease activity, (2) Correlate EoEHSS grade and stage subcomponents to clinical, radiology, and endoscopic markers of fibrotic disease, (3) Evaluate EoEHSS remission in asymptomatic patients with PEC < 15 eosinophils per high powered field (eos/hpf). METHODS Secondary analysis of prospective cohort data of 22 patients with EoE that underwent dietary therapy and endoscopy at 3 time points. Active disease was defined by EoEHSS grade or stage > 0.125, symptomatic disease by EoE symptom activity index > 20, endoscopic disease by endoscopic reference score > 2, and histologic disease by PEC ≥ 15 eos/hpf. EoEHSS remission was defined by esophageal inflammation (EI) grade of 0-1, EI stage of 0, total grade ≤ 3, and total stage ≤ 3. RESULTS EoEHSS grade and stage did not correlate with symptomatic disease but did with endoscopic and histologic disease. PEC showed similar correlation pattern. Abnormal grade and stage had strong sensitivity (87-100%) but poor specificity (11-36%) to detect symptomatic, endoscopic, and histologic disease activity. Lamina propria fibrosis was evaluated in 36% of biopsies and did not correlate with minimum esophageal diameter. Out of 14 patients who were in complete symptomatic, endoscopic, and histologic remission, 8 met criteria for EoEHSS remission. CONCLUSION The positive and negative correlations of EoEHSS to specific measures of symptomatic, histologic, and endoscopic activity suggest that it provides complementary information in EoE.

Abstract
Since the first description of eosinophilic oesophagitis (EoE) less than three decades ago, we have observed a striking increase in the number of patients diagnosed with EoE and the understanding of its clinical and immunopathogenic background. Nonetheless, a plethora of open questions await elucidation. In this Review, we discuss the current state of knowledge regarding the underlying mechanisms, particularly environmental factors and their interaction with genetic susceptibility. Subsequently, we discuss how to translate these factors into the diagnostic and therapeutic management of this chronic, immune-mediated disorder. Finally, we dissect the still long list of unmet needs, such as reasons for and handling refractory EoE and atypical clinical presentations. These open questions can guide us through future research steps and potentially foster reconsideration of the diagnostic guidelines of EoE.

Abstract
Eosinophilic esophagitis (EoE) is a chronic, immune-mediated inflammatory disease, characterized by esophageal dysfunction and intense eosinophil infiltration localized in the esophagus. In recent decades, EoE has become a growing concern as a major cause of dysphagia and food impaction in adolescents and adults. EoE is a clinicopathological disease for which the histological demonstration of esophageal eosinophilia is essential for diagnosis. Therefore, the recognition of the characteristic endoscopic features with subsequent biopsy are critical for early definitive diagnosis and treatment, in order to prevent complications. Accumulating reports have revealed that EoE has several non-specific characteristic endoscopic findings, such as rings, furrows, white exudates, stricture/narrowing, edema, and crepe-paper esophagus. These findings were recently unified under the EoE endoscopic reference score (EREFS), which has been widely used as an objective, standard measurement for endoscopic EoE assessment. However, the diagnostic consistency of those findings among endoscopists is still inadequate, leading to underdiagnosis or misdiagnosis. Some endoscopic findings suggestive of EoE, such as multiple polypoid lesions, caterpillar sign, ankylosaurus back sign, and tug sign/pull sign, will aid the diagnosis. In addition, image-enhanced endoscopy represented by narrow band imaging, endocytoscopy, and artificial intelligence are expected to render endoscopic diagnosis more efficient and less invasive. This review focuses on suggestions for endoscopic assessment and biopsy, including recent advances in optical technology which may improve the diagnosis of EoE.

Abstract
Abstract
Background Eosinophilic Esophagitis (EoE) has received increasing attention as a disease entity, and it is now recognized as an important disorder of the Upper Gastrointestinal Tract. Topical corticosteroids (tCS) are effective in clinical-pathological remission induction (RI) and remission maintenance (RM) of active EoE. With scoring systems, such as clinical (SDI), endoscopic (EREFS), and histological (EoEHSS) systems, EoE can be graded, and its disease activity can be assessed.
Objective To discover how closely results within each of the three scoring systems SDI, EREFS, and EoEHSS are correlated between initial diagnosis (ID), RI, and RM, and to determine how well scores from the three systems are intercorrelated at each time point.
Methods Retrospective cohort analysis of patients with active EoE was performed between 2006 and 2020, with follow-up for up to 6 years. SDI, EREFS and EoEHSS scores were recorded at ID, at RI, and in RM. Evaluation employed descriptive statistics, the Friedman test, and Bonferroni-corrected post hoc pairwise comparisons.
Results At RI 29 and at RM 19 EoE patients provided data. Significant correlations were found between EREFS and EoEHSS at RI and in RM. Pairwise comparisons showed significant differences between ID and RI for SDI, for EREFS, and for EoEHSS.
Conclusion The scoring systems tested did not show intercorrelation at ID. Comparison revealed significant differences for SDI, EREFS, and EoEHSS between the systems at ID und RI, but not in RM, during tCS treatment. These results underline the efficacy of tCS (at RI and RM) in the treatment of active EoE.

Aliment Pharmacol Ther 2022; 56:1328-1336. [PMID: 36127308 DOI: 10.1111/apt.17220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 05/20/2022] [Accepted: 09/01/2022] [Indexed: 01/30/2023]
Abstract
BACKGROUND Eosinophilic oesophagitis (EoE) is associated with elevated IgG4 in oesophageal tissue and serum. Previously, we showed brush-collected oesophageal secretions of EoE patients contained food antigen-specific antibodies IgA and IgG4. It is unknown whether other food-specific antibodies are present along the surface of the oesophagus in EoE. AIM To identify whether immunoglobulins other than IgG4 and food-specific antibodies are elevated along the oesophageal mucosal surface in oesophageal secretions in EoE patients METHODS: Concentrations of total IgA, IgG1, IgG2, IgG3, IgG4, IgM and IgE were measured in oesophageal secretions from patients with active (n = 19) and inactive EoE (n = 9), and non-EoE controls (n = 10). Food-specific antibodies were measured using beads coupled to protein components from dairy, wheat and egg. Total immunoglobulin and cytokine and chemokine concentrations were measured in serum, saliva and oesophageal secretions of four patients with active EoE. RESULTS Oesophageal secretions have a unique immune profile. Patients with active EoE had elevated IgG2, IgG4 and IgM concentrations in oesophageal secretions compared to those with inactive EoE. Food-specific IgG1, IgG2, IgG4 and IgM were significantly increased in patients with active EoE compared to inactive EoE and non-EoE patients. Furthermore, active patients with a known dairy trigger display higher dairy-specific IgG1, IgG2, IgG4, IgM, IgA and IgE. CONCLUSIONS There is a distinct localised profile of immunoglobulins and food-specific antibodies found within oesophageal secretions in EoE. These findings expand our knowledge about the currently identified immune responses in EoE and suggest possible roles for multiple immunoglobulins and food-specific antibodies in the pathophysiology of EoE.

Abstract
Eosinophilic esophagitis (EoE) is a chronic inflammatory condition of the esophagus characterized by increased number of eosinophils. Currently, EoE diagnosis is based on endoscopic procedures for histopathological examination, eosinophils' counting and, often, in clinical practice, the challenge is the differentiation between EoE and gastroesophageal reflux disease (GERD). Our aim was to develop novel peptide ligand to Eosinophil cationic protein (ECP) present in EoE biopsies of patients with potential to be used for detection. We performed a comparative proteomic analysis using liquid chromatography-tandem mass spectrometry (LC-MS/MS) of esophageal biopsies from pediatric patients with eosinophilic esophagitis, gastroesophageal reflux disease and control individuals. Then, phage display technology was used to select peptides against specific up-regulated protein from EoE patients. Twelve phage clones were selected after three biopanning rounds, and the best phage clone reactivity was evaluated by phage-ELISA assay using esophageal mucus samples from 94 pediatric patients. Mass spectrometry showed that eosinophil cationic protein (ECP) was one of the most up-regulated proteins in EoE patients, which is an eosinophil granule protein usually deposited on tissues to mediate remodeling, but in excess may cause fibrosis and hypertrophy, especially in allergic responses. A highly reactive ECP-ligand peptide (E5) was able to distinguish reactive mucus of EoE patients from GERD and the control individuals by Phage-ELISA, achieving a sensitivity of 84.62%, and a specificity of 82.72%. This is the first study that successfully demonstrated an antibody-like peptide targeting ECP at the esophagus mucus as a useful auxilliary tool for EoE diagnosis with a significant association with atopic disorders and dysphagia.ClinicalTrials.gov no.: NCT03069573.

Abstract
BACKGROUND & AIMS Disease activity and severity of eosinophilic esophagitis (EoE) dictate therapeutic options and management, but the decision-making process for determining severity varies among practitioners. To reduce variability in practice patterns and help clinicians monitor the clinical course of the disease in an office setting, we aimed to create an international consensus severity scoring index for EoE. METHODS A multidisciplinary international group of adult and pediatric EoE researchers and clinicians, as well as non-EoE allergy immunology and gastroenterology experts, formed 3 teams to review the existing literature on histology, endoscopy, and symptoms of EoE in the context of progression and severity. A steering committee convened a 1-day virtual meeting to reach consensus on each team's opinion on salient features of severity across key clinicopathologic domains and distill features that would allow providers to categorize disease severity. RESULTS Symptom features and complications and inflammatory and fibrostenotic features on both endoscopic and histologic examination were collated into a simplified scoring system-the Index of Severity for Eosinophilic Esophagitis (I-SEE)-that can be completed at routine clinic visits to assess disease severity using a point scale of 0-6 for mild, 7-14 for moderate, and ≥15 for severe EoE. CONCLUSIONS A multidisciplinary team of experts iteratively created a clinically usable EoE severity scoring system denominated "I-SEE" to guide practitioners in EoE management by standardizing disease components reflecting disease severity beyond eosinophil counts. I-SEE should be validated and refined using data from future clinical trials and routine clinical practice to increase its utilization and functionality.

Abstract
BACKGROUND Endoscopic features of eosinophilic esophagitis (EoE) are measured using the validated EoE Endoscopic Reference Score (EREFS); however, a threshold for treatment response has not been defined. We aimed to determine a cut-point for endoscopic response as measured by EREFS. METHODS We performed a secondary analysis of a randomized clinical trial comparing budesonide slurry with swallowed fluticasone multidose inhaler for initial treatment of EoE. In the parent trial, EREFS was determined before and after treatment (score range 0-9), as were histologic findings and dysphagia symptoms. We performed tabular, flexible trend, and dependent mixture analyses of measures of treatment response to select the best clinical EREFS threshold. RESULTS In the 111 included patients (mean age 39 years; 67 % male; 96 % white), an EREFS threshold of ≤ 2 was 80 % sensitive (95 % confidence interval [CI] 69 % to 88 %) and 83 % specific (95 %CI 67 % to 94 %) for histologic response (peak of < 15 eosinophils per high-power field). Flexible trend analysis and dependent mixture modeling similarly suggested that a threshold of ≤ 2 best captured the correlation of EREFS with histologic and symptomatic measures. Dependent mixture modeling found near-total membership in the response class at EREFS of 0 or 1 and > 75 % at EREFS of 2 or 3. CONCLUSIONS An EREFS of ≤ 2 was the best clinical threshold for endoscopic response to topical steroid treatment, and was consistent with clinical and histologic response. Therefore, future studies can report a binary outcome of endoscopic response when EREFS is 2 or less.

Abstract
INTRODUCTION Collins et al developed a histology scoring system (EoE HSS) to assess multiple pathologic features. The aim of this study is to identify if the EoE HSS can better detect endoscopic and symptom improvement vs the Peak Eosinophilic Count (PEC). METHODS A retrospective chart review was performed for patients during 2014-2016. All patients ≤18 years old with a diagnosis of EoE and whose records included initial and follow-up upper gastrointestinal endoscopies were included. Severity and extent of endoscopic features were scored using 8 parameters, from normal to maximum change for each location of the esophageal biopsy. RESULTS Forty patients with EoE were included in the study, of which 35 (87.5%) patients demonstrated symptom and 25 (62.5%) endoscopic improvement at the time of follow-up. In the proximal esophagus, the EoE HSS outperformed the change in eosinophil count of the Children's Hospital of Eastern Ontario (CHEO) practice in predicting endoscopic improvement by 16.8% when examining the change in grade and 17.1% when examining the change in stage scores. CONCLUSIONS At our institution, adoption of the EoE HSS in assessing biopsies of EoE patients might be warranted, compared to the traditional practice. However, a bigger sample size may give a more robust difference in all locations.

Clin Gastroenterol Hepatol 2022; 20:e957-e963. [PMID: 33221551 DOI: 10.1016/j.cgh.2020.11.023] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 10/29/2020] [Accepted: 11/14/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Familial clustering of eosinophilic esophagitis (EoE) has been described, and we report on the biopsy-assessed prevalence of esophageal eosinophilia (EE) in first-degree family members. The aim was to determine the prevalence of EE in first-degree adult relatives (FDRs) of EoE patients. METHODS Index EoE patients diagnosed by EE (>15 eosinophils per high-power field) and proton pump inhibitor nonresponsiveness were identified and family trees were constructed. Adult FDRs were invited to undergo upper endoscopy with esophageal biopsies and to complete reflux, dysphagia, and allergy/atopy questionnaires. Questionnaire information was gathered only for those who responded as per institutional review board purview. Records from other children and adult FDRs with prior EoE diagnoses also were obtained when permission was obtained. Simple and multivariable logistic regression models were used to evaluate the unadjusted and odds ratios of EoE for demographic and clinical variables. RESULTS A total of 239 FDRs from 37 index EoE patients were identified. Seventy-one of 239 adult (age, >18 y) FDRs completed endoscopy and questionnaires and 18 of 71 FDRs had EE. An additional 17 FDRs were confirmed to have EE after external medical record retrieval, resulting in a total of 35 of 239 (14.6%) FDRs with EE. Significantly more male FDRs had EE compared with female FDRs (P = .027). Proton pump inhibitors, dysphagia, gastroesophageal reflux disease, asthma, and reflux symptoms predicted EE in FDRs. FDRs who had EE reported hay fever, allergic eye symptoms, and food allergy more frequently than those without EE (P = .03, P = .001, and P = .02, respectively). Specifically, younger age, higher serum eosinophils, being male, and having food allergies all were associated with higher odds of EoE (P = .0211, P = .0031, P = .0362, and P = .0089, respectively). CONCLUSIONS The prevalence of esophageal eosinophilia is extremely high and male-predominant in first-degree relatives of EoE patients. Symptoms of hay fever, allergic eye symptoms, and food allergy were predictors of EE in FDRs. Dysphagia did not predict esophageal eosinophilia. Family members of EoE patients are at risk for EE, particularly those who have atopic symptoms.

Abstract
INTRODUCTION Eosinophilic esophagitis (EoE) is a clinical and pathological disorder, characterized by symptoms of esophageal dysfunction, and eosinophil-predominant inflammation restricted to the esophagus. Treatment outcomes include symptomatic remission, histological and endoscopic normalization and improving quality of life. Besides dietary modifications and endoscopic dilation, drugs available are swallowed topical corticosteroids (STCs) with reduced bioavailability and proton pump inhibitors (PPI). AREAS COVERED Herein, the authors review the current treatment strategies for EoE in adults, providing the reader with their expert perspectives. The authors give discussion to the value of PPIs as a first-line therapy for EoE, in addition to the use of STCs. The current development of new formulations of STCs targeting the esophagus and novel therapies aimed at blocking molecular pathways are also discussed. Finally, the authors briefly look at the value of monoclonal antibodies targeting IL-5RA, IL-13, IL-4 or Siglec8, and oral S1PR agonists to the treatment of EoE. EXPERT OPINION Viscose formulations of STC designed to coat the esophagus and new effervescent orodispersible tablets provide increased effectiveness at low doses. Investigational therapies that target several Th2-associated diseases seem useful in EoE. Comparative effectiveness and cost-utility analyses will help to position them in a complex therapeutic scenario.

Abstract
Eosinophilic esophagitis (EoE) is a chronic, immune/antigen-mediated esophageal disease characterized by symptoms of esophageal dysfunction and eosinophil-predominant inflammation. The diagnostic criteria for EoE have changed with our growing knowledge over the past two decades. Esophageal eosinophilia, which responds histologically to a proton pump inhibitor (PPI) is not a distinct disease but a subset of EoE. An endoscopic scoring system that relies on the assessment of exudates, rings, edema, furrows, and strictures is a useful tool for assessing endoscopic severity. PPIs are regarded as safe and effective first-line treatments for EoE. Oral topical corticosteroids or dietary therapy are also options for first-line treatment. Endoscopic dilation is effective for relieving the dysphagia symptoms of a patient with an esophageal stricture.

Abstract
BACKGROUND For eosinophilic esophagitis (EoE), a substantial diagnostic delay is still a clinically relevant phenomenon. Deep learning-based algorithms have demonstrated potential in medical image analysis. Here we establish a convolutional neuronal network (CNN)-based approach that can distinguish the appearance of EoE from normal findings and candida esophagitis. METHODS We trained and tested a CNN using 484 real-world endoscopic images from 134 subjects consisting of three classes (normal, EoE, and candidiasis). Images were split into two completely independent datasets. The proposed approach was evaluated against three trainee endoscopists using the test set. Model-explainability was enhanced by deep Taylor decomposition. RESULTS Global accuracy (0.915 [95 % confidence interval (CI) 0.880-0.940]), sensitivity (0.871 [95 %CI 0.819-0.910]), and specificity (0.936 [95 %CI 0.910-0.955]) were significantly higher than for the endoscopists on the test set. Global area under the receiver operating characteristic curve was 0.966 [95 %CI 0.954-0.975]. Results were highly reproducible. Explainability analysis found that the algorithm identified the characteristic signs also used by endoscopists. CONCLUSIONS Complex endoscopic classification tasks including more than two classes can be solved by CNN-based algorithms. Therefore, our algorithm may assist clinicians in making the diagnosis of EoE.

Abstract
Eosinophilic esophagitis (EoE) is an antigen-mediated esophageal disease defined by the presence of esophageal eosinophilia and symptoms of esophageal dysfunction. The pathophysiology involves an allergen-driven Th2 T cell response that triggers infiltration of eosinophils into the esophagus leading to inflammation, remodeling, and fibrosis. This results in disruption of esophageal function and accompanying symptoms - most notably dysphagia. Effective therapies target inflammation or fibrostenotic complications and include proton pump inhibitors, swallowed topical steroids, dietary exclusion, and dilation. Clinical trials testing promising biologic therapies are ongoing.

Abstract
The eosinophilic esophagitis (EoE) endoscopic reference score (EREFS) is a validated system for description, recognition, and reporting of EoE findings during esophagogastroduodenoscopy (EGD). This scoring system correlates with esophageal eosinophilia and therapeutic responses and has validated diagnostic accuracy with good inter- and intraobserver reliability in pediatric and adult patients. In this study, we aimed to improve physician education on and documentation of EREFS and correlate EREFS scoring with eosinophil density on histology. Methods Applying the "Plan, Do, Study, Act" methodology for quality improvement between October 2018 and November 2019, we established a baseline rate of EREFS completion by review of the electronic medical record (EMR). Key drivers were identified, and 3 interventions were implemented. Results Over 12 months, 542 distinct endoscopies were performed on 410 patients for EoE surveillance. Patients were 68% male with a mean age of 10.9 years (SD 5.7 years), mean EREFS score of 2.14 (SD 1.88), and mean peak eosinophil count 30.9 eos/hpf (SD 37.1 eos/hpf). Baseline EREFS completion rate of 72.7% (90% CI, 67.4-77.4). Following all 3 PDSA cycles, EREFS completion rate significantly improved to greater than desired target of 90% (94.9%; 90% CI, 90.6-97.6; P < 0.001). Conclusion Interventions including provider education and the inclusion of EREFS in documentation templates can increase adoption rates of EREFS among providers caring for patients with known EoE.

Abstract
BACKGROUND AND STUDY AIMS Eosinophilic oesophagitis (EoE) is a common disease with a significant impact on physical health and quality of life (QoL). Outcomes and management vary widely, with no agreed UK national guideline. This paper aims to describe an up-to-date description of demographics, clinical spectrum and outcomes for paediatric and adult patients with EoE from the North East of England between 2016 and 2019. PATIENTS AND METHODS Patients from two large University Hospitals and the specialist paediatric hospital for the North East of England with histologically or clinically confirmed EoE were included in this analysis. Data were collected retrospectively via electronic patient records. Remission was defined as either the resolution of symptoms or improvement on histology. RESULTS Data were collected on 74 paediatric and 59 adult patients. Dysphagia was the most common presenting symptom in both groups, accounting for 51%-84% of all presentations. Proton pump inhibitors and dietary manipulation were the most common therapies associated with remission in children (95% of those achieving remission), whereas the use of swallowed topical steroids was more prevalent in the treatment of adults (55% achieving remission). CONCLUSIONS EoE is a complex disease and poses significant challenges. Outcomes vary widely and need to be tailored to individual patient groups. Dietary manipulation plays a major role in treatment for EoE, but this is likely to be challenging for patients, especially children. Future work should continue to assess the outcomes in EoE, including on QoL and potential novel targeted therapies.

Abstract
In the absence of secondary causes, eosinophilic esophagitis (EoE) is a chronic, local, progressive, T-helper type 2 immune-mediated disorder characterized by symptoms of esophageal dysfunction and eosinophil-predominant inflammation. In the last 20 years, the incidence and prevalence of EoE have risen sharply, and the chances of encountering affected patients in clinics and endoscopy rooms have increased. Nevertheless, it is estimated that the mean diagnostic delay of EoE is 4-6 years in both children and adults. Unfortunately, the longer the disease stays unrecognized, the likelier it is for the patient to have persistent or increased esophageal eosinophilic inflammation, to complain of non-resolving symptoms, and to develop fibrotic complications. Early detection depends on the recognition of initial clinical manifestations that vary from childhood to adulthood and even among patients of the same age. The disease phenotype also influences therapeutic approaches that include drugs, dietary interventions, and esophageal dilation. We have herein reviewed epidemiologic, clinical, endoscopic, and histologic features and therapeutic options of EoE focusing on differences and similarities between children and adults that may certainly serve in daily clinical practice.

Abstract
BACKGROUND Although several endoscopic findings of eosinophilic esophagitis (EoE), such as the EoE endoscopic reference score (EREFS), have been reported thus far, these endoscopic findings exhibit low specificity. Furthermore, most of these endoscopic findings were evaluated solely in patients from Western nations. We have recently noted a fragile, protruded mucosal lesion sandwiched between longitudinal furrows (similar to caterpillar tracks) on the esophagus in patients with EoE. We have termed this novel finding the "caterpillar sign". This study evaluated the clinical significance of the caterpillar sign and the EREFS for diagnosis of EoE in Japanese patients. METHODS We retrospectively analyzed endoscopic images from 165 consecutive patients who underwent tissue collection on suspicion of EoE. We compared the clinical significance between the EREFS and the caterpillar sign. We defined EoE as the presence of ≥ 15 eosinophils on esophageal mucosa per high-power field; control images had < 15 eosinophils per high-power field. For evaluation of endoscopic diagnosis capacity using the total EREFS, 2 points was set as the cutoff value. The presence or absence of the caterpillar sign was evaluated. RESULTS The sensitivity, specificity, positive predictive value, and negative predictive value of total EREFS ≥ 2 for the diagnosis of EoE were 100%, 56.2%, 56.6%, and 100%; for the caterpillar sign, those values were 83.3%, 98.1%, 96.2%, and 91.2%, respectively. Interobserver agreement for identification of the caterpillar sign was substantial (κ = 0.80) CONCLUSIONS: The caterpillar sign could be a novel reliable indicator for endoscopic diagnosis of EoE.

Abstract
Endoscopy and mucosal biopsies are essential to the diagnosis of EoE. Together they either confirm or exclude mucosal eosinophilia and provide a visual inspection of the esophagus that may be consistent with EoE or suggest other underlying etiologies. Endoscopy also plays an important therapeutic role in the management of EoE including the assessment of treatment response and treatment of associated complications including esophageal stricture and food impaction. Assessment of treatment response largely depends on endoscopy and mucosal biopsies although less invasive strategies may eventually provide alternative means to assess mucosal inflammation. Herein we will review current use of endoscopy in EoE, including recently developed technologies and their role in the management of EoE.

Abstract
Endoscopy plays an important role in the management of eosinophilic esophagitis (EoE), since it is involved in the diagnosis, follow-up and treatment of this condition. In patients presenting with food impaction, dysphagia and other symptoms of suspected EoE, esophago-gastric-duodenoscopy (EGD) with multiple esophageal biopsies should be performed to confirm or rule out the diagnosis of EoE. The EREFS system, a validated instrument for assessment of the endoscopically-identified esophageal features in EoE (edema, rings, exudates, longitudinal furrows and strictures), is currently used in the clinical practice for the evaluation of the macroscopic aspects of esophageal mucosa during EGD. Multiple esophageal biopsies are mandatory to further confirm EoE diagnosis and subsequent response to treatment, since symptoms reported by patients do not always correlate with histological activity, and considering the low sensitivity of endoscopic assessment; a cut-off of ≥15 eosinophils in at least one high power field is the density threshold considered the standard for diagnosis (sensitivity 100%, specificity 96%). Other histological features, included in the EoE histologic scoring system (EoEHSS), are supportive for the diagnosis and for the assessment of inflammatory activity during follow-up. Esophageal dilation, performed either with Savary dilators/bougie or hydrostatic balloon, is an effective and safe treatment in both adult and pediatric EoE patients with fibrostenotic features, mainly in association with other therapeutic strategies which can control eosinophilic inflammation.

Abstract
Eosinophilic esophagitis (EoE) is characterized by eosinophilic infiltration of the esophageal mucosa and symptoms of esophageal dysfunction, including dysphagia. While EoE is still considered a rare disease, in practice it seems that more and more cases are diagnosed every week, research in the field is exploding, and the pipeline for treatments contains multiple agents, some of which are quite far along the development pathway. After only scattered cases and small series were published in the late 1970s and 1980, Stephen Attwood, Thomas Smyrk, Tom DeMeester, and James Jones, published in Digestive Diseases and Sciences in 1993 a seminal report that described a clinicopathologic syndrome of esophageal eosinophilia with dysphagia. This review details the origins of this paper and compares and contrast what was observed then and what is known now about multiple aspects of EoE, including the clinical presentation, diagnosis, epidemiology, natural history, and treatments and outcomes. Moreover, it will highlight how the paper presaged a number of controversies in the field that have yet to be resolved, as well as foreshadowed the collaborative, multidisciplinary approach that has led to rapid advances.

Abstract
Eosinophilic esophagitis (EoE) is an allergen-driven chronic inflammatory condition, characterized by symptoms related to esophageal dysfunction and confirmed histologically by esophageal mucosal eosinophilia. Since its first description in the 1990s, the incidence and prevalence of EoE have been on the rise. It is known to affect all ages of various ethnic backgrounds and both sexes; however, it is most seen in White males. Children with EoE often present with abdominal pain, nausea, vomiting, and failure to thrive, whereas adults with EoE typically present with dysphagia and food impaction. Diagnosis of EoE requires histologic confirmation of elevated esophageal eosinophils in a symptomatic patient, and only after secondary causes have been excluded. Because EoE is a chronic and progressively fibrostenotic disease, treatment goals include resolution of symptoms, induction and maintenance of disease remission, and prevention and possibly reversal of fibrostenotic complications, while minimizing treatment-related adverse effects and improving quality of life. Treatment strategies include the "3 D's"-drugs, diet, and dilation. Standard drug therapies include proton-pump inhibitors and topical corticosteroids. Dietary therapies include elemental diet, allergy testing-directed elimination diet, and empiric elimination diets. Endoscopic esophageal dilation for EoE strictures can alleviate esophageal symptoms but has no effect on mucosal inflammation. Recent progress in EoE research has made possible evidence-based clinical guidelines. Ongoing pharmacologic trials show promise for novel biologic agents in the treatment of refractory EoE.

Abstract
Eosinophilic esophagitis (EoE) is a clinicopathologic disease characterized by symptoms of esophageal dysfunction and esophageal eosinophilia. In the last decade, there has been a dramatic increase in its prevalence for reasons that are not completely understood. The underlying pathophysiology involves an antigen-mediated TH 2 immune response that draws eosinophils to the esophagus, causing mucosal inflammation, esophageal remodeling, and fibrosis. This ultimately leads to esophageal dysfunction that most commonly manifests as dysphagia. In this review, we will discuss updates on key questions regarding the diagnosis and treatment of EoE.

Abstract
Budesonide oral suspension (BOS) is a novel topical corticosteroid, which has been shown to improve symptoms and endoscopic appearance, and reduce peak eosinophil counts in patients with eosinophilic esophagitis (EoE). This trial evaluated the effect of BOS or placebo on the severity (grade) and extent (stage) of 8 histopathologic features observed in EoE, using the validated eosinophilic esophagitis histologic scoring system (EoE HSS). Patients with EoE aged 11 to 40 years with dysphagia were randomized to receive either BOS (2.0 mg twice daily) or placebo for 12 weeks. Mean (SD) EoE HSS grade and stage total scores at baseline for placebo and BOS groups were: grade, 0.42 (0.16) and 0.49 (0.14), respectively; stage: 0.38 (0.14) and 0.46 (0.11), respectively. These scores significantly decreased (improved) from baseline for patients receiving BOS versus placebo (grade: least squares mean change [SE]: placebo vs. BOS, -0.04 [0.03] vs. -0.24 [0.02]; P<0.0001; stage: -0.01 [0.02] vs. -0.19 [0.02]; P<0.0001). EoE HSS total scores improved for 6 of the 8 and 5 of the 8 histopathologic features for grade and stage, respectively, versus placebo. Change in EoE HSS total scores correlated moderately but significantly with change in endoscopic severity (endoscopic reference score; grade: R=0.5349; stage: R=0.5416; both P<0.0001). Change in EoE HSS stage total score correlated weakly with change in Dysphagia Symptom Questionnaire scores (grade: R=0.1925; P=0.0740; stage: R=0.2135; P=0.0471). These data demonstrate that the EoE HSS is a valuable endpoint of treatment response in randomized clinical trials and should be considered for future trials for EoE.

Abstract
BACKGROUND AND AIMS In children with eosinophilic esophagitis (EoE), the relationship among the endoscopic reference score (EREFS), the histology scoring system (EoEHSS), and the peak eosinophil count (PEC) is incompletely described. Our aim was to determine the relationship among EREFS, EoEHSS, and PEC and develop a predictive model using components of EREFS and EoEHSS for EoE activity. METHODS We analyzed 189 paired EREFSs, EoEHSSs, and PECs. Active EoE (aEoE; n = 98) was defined as ≥15 eosinophils per high-power field and inactive EoE (iEoE; n = 91) as <15 eosinophils per high-power field. Spearman correlation (r) with Bonferroni correction was used to assess the relationship between EREFS, EoEHSS and PEC, and a back-transformed average Fisher test was used to determine the statistical significance of the differences. Receiver operating characteristic analysis was used to develop the predictive model. RESULTS The relationship between total EREFS and EoEHSS was modest (r = 0.61) but significantly stronger than the correlation between total EREFS and PEC (r = 0.55; P = .04). The relationship between total EREFS and EoEHSS tended to be stronger in aEoE compared with iEoE (r = 0.41 vs 0.24; P = .09). Compared with EREFS, EoEHSS had a significantly higher area under the curve (0.78 vs 0.92; P = .04) to predict aEoE. A combination of furrows, eosinophilic inflammation, basal cell hyperplasia, eosinophilic abscess, and dilated intercellular spaces had an area under the curve of 0.97, accuracy of 98%, sensitivity of 97%, and specificity of 98% to predict aEoE. CONCLUSIONS The endoscopy score modestly correlates with the histologic scoring system. Thus, the endoscopy score is not a reliable marker of tissue involvement in EoE. A panel of individual endoscopic and histologic signs hold promise to accurately predict EoE activity.

Abstract
While the diagnosis and initial treatment of eosinophilic esophagitis are becoming more standardized, there are still major gaps in knowledge related to measuring treatment response. One such question centers on how to measure treatment response and what treatment endpoints should be. This impacts not only patient care and engagement in decision-making, but also the field of drug development. In addition, studies so far have use a myriad of treatment endpoints including over a dozen histologic endpoint criteria. This review will discuss the various stakeholders involved in assessment of treatment endpoints of a complex condition, including patients, practitioners and regulatory agencies, and the care settings in which treatment response is assessed, including routine clinical care, clinical trials, and observational studies. Potential parameters or treatment endpoints such as histology, symptoms, patient-reported outcomes, endoscopy, and biomarkers are discussed along with associated challenges and opportunities. A framework on how to define treatment outcomes is discussed and a conceptual approach treatment response is proposed. This takes into account histology, symptoms, and endoscopic findings and harnesses existing, validated tools. It includes definitions of nonresponse, complete normalization, and a graded response category between these 2 extremes, and also permits flexibility and latitude for modifications as newer knowledge emerges. In addition, ways to position the pediatric population in these endeavors are discussed as are future research directions.

Abstract
BACKGROUND & AIMS Eosinophilic esophagitis (EoE) is assessed endoscopically (endoscopic activity), based on grades of edema, rings, exudates, furrows, and strictures (EREFS). We examined variations in endoscopic assessments of severity, developed and validated 3 EREFS-based scoring systems, and assessed responsiveness of these systems using data from a randomized placebo-controlled trial of patients with EoE. METHODS For the development set, 5 gastroenterologists reviewed EREFS findings from 266 adults with EoE and provided endoscopist global assessment scores (EndoGA, scale of 0 to 10); variation (ΔEndoGA) was assessed using linear regression. We evaluated simple scores (features given arbitrary values from 0 to 3) and developed 2 scoring systems (adjusted score range, 0-100). We then fitted our linear regression model with mean EndoGA to data from 146 adults recruited in centers in Switzerland and the United States between April 2011 and December 2012. For the validation set, we collected data from 120 separate adults (recruited in centers in Switzerland and the United States between May 2013 and July 2014), assessing regression coefficient-based scores using Bland-Altman method. We assessed the responsiveness of our scoring systems using data from a randomized trial of patients with EoE given fluticasone (n=16) or placebo (n=8). RESULTS The distribution of EndoGA values differed among endoscopists (mean ΔEndoGA, 2.6±1.8; range 0-6.6). We developed 2 regression-based scoring systems to assess overall and proximal and distal esophageal findings; variation in endoscopic features accounted for more than 90% of the mean EndoGA variation. In the validation group, differences between mean EndoGA and regression-based scores were small (ranging from -4.70 to 2.03), indicating good agreement. In analyses of data from the randomized trial, the baseline to end of study change in patients given fluticasone was a reduction of 24.3 in simple score (reduction of 4.6 in patients given placebo, P=.052); a reduction of 23.5 in regression-based overall score (reduction of 6.56 in patients given placebo, P=.12), and a reduction of 23.8 (reduction of 8.44 in patients given placebo, P=.11). CONCLUSION Assessments of endoscopic activity in patients with EoE vary among endoscopists. In an analysis of data from a randomized controlled trial, we found that newly developed scoring systems are no better than simple scoring system in detecting changes in endoscopic activity. These results support the use of a simple scoring system in evaluation of endoscopic activity in patients with EoE. clinicaltrials.gov no: NCT00939263 and NCT01386112.

Abstract
Background and study aims Endoscopic findings of esophageal eosinophilia sometimes localize to small areas of the esophagus. A previous study suggested that pathogenesis of localized-type eosinophilic esophagitis (LEoE) was associated with acid reflux. However, LEoE treatment outcomes have not been studied. We aimed to analyze the clinical and histologic significance of LEoE in comparison with diffuse-type eosinophilic esophagitis (DEoE). Patients and methods This study included 106 patients with esophageal eosinophilia. Esophageal eosinophilia was defined as a condition where the maximum number of intraepithelial eosinophils was ≥ 15 per high-power field. LEoE was defined as an endoscopic lesion confined to one-third of the esophagus: upper, middle, or lower. Esophageal eosinophilia encompassing more than two-thirds of the esophagus was defined as DEoE. We retrospectively compared LEoE and DEoE in terms of clinical characteristics, histologic findings, and proportion of proton pump inhibitor (PPI) responders. Results Of 106 patients, 12 were classified as having LEoE and 94 were classified as having DEoE. The proportion of asymptomatic patients was significantly higher in the LEoE group than the DEoE group (42 % vs 7 %, P < 0.01). In the LEoE group, 10 patients (84 %) had endoscopic lesions in the lower esophagus. The maximum number of eosinophils did not differ between the groups (54 [24 - 71] for LEoE, 40 [20 - 75] for DEoE, P = 0.65). The prevalence of PPI responders was significantly higher in the LEoE group than the DEoE group (100 % vs 63 %, P = 0.01). Conclusion LEoE can be a sign of good responsiveness to PPI therapy.

Comparison of mucosal impedance measurements throughout the esophagus and mucosal eosinophil counts in endoscopic biopsy specimens in eosinophilic esophagitis. Gastrointest Endosc 2019; 89:693-700.e1.

Abstract
BACKGROUND AND AIMS Assessing eosinophilic esophagitis (EoE) activity from limited esophageal mucosal biopsy samples has been questioned. Here our aim was to compare mucosal impedance (MI) throughout the esophagus and eosinophil counts in endoscopic biopsy samples in EoE. METHODS We compared 20-site MI using a balloon catheter in the esophagus and eosinophils per high-power field (eos/HPF) in esophageal mucosal biopsy samples. Data are summarized as median (interquartile range) comparing control subjects and EoE using Mann-Whitney rank sum test and between endoscopic reference score and MI (minimal and average) using rank Spearman correlation. RESULTS Ten adult control patients (ages 38-70) and 23 EoE patients (ages 21-80, 18 active) were studied. The mean (range) pan-esophageal MI in control subjects was significantly higher (6435 ohms [4546-7301]) compared with EoE patients (2004 ohms [1437-2546], P < .001). In control patients 172 of 180 (95.6%) individual impedance measurements (18 per patient) were normal when compared with 126 of 432 (29.2%) measurements in EoE. No EoE patient had uniformly normal MI. MI varied widely, with 19 of 23 patients having values above and below 2300 ohms (normal) regardless of EoE activity. Correlation of maximim eos/HPF with minimum and average MI per patient was r = -.243, P = .072 and r = -.358, P = .086, respectively. Of 5 patients with inactive EoE, 3 had >50% abnormal MI segments. Correlation coefficients of the endoscopic reference score with minimum and average MI were r = -.154, P = .47 and r = -.27, P = .20, respectively. The procedure was <5 minutes without adverse events. CONCLUSIONS MI is lower in the esophagus of EoE patients compared with control subjects with poor correlation between peak esophageal eosinophil counts, EoE activity, and MI. Segmental esophageal MI provides a unique marker of esophageal dysfunction in EoE. (Clinical trial registration number: NCT02995395.).

Abstract
Because of its high incidence gastroesophageal reflux disease (GERD) is at the forefront of medical attention. On the other hand, vigilance for rare inflammatory diseases of the esophagus, such as herpes esophagitis, radiation-induced esophagitis, eosinophilic esophagitis, pseudodiverticulosis and Crohn's disease is low. Moreover, these entities are rarely distinguishable from GERD by clinical features alone. For all atypical and treatment refractory supposedly reflux diseases, the diagnosis should therefore be questioned and re-evaluated by endoscopy. When the macroscopic findings of esophagoscopy are ambiguous biopsies can be performed and histological examination then often leads to a definitive diagnosis. This is particularly important because the required treatment of rare forms of esophagitis often significantly differs from that of GERD.

Abstract
BACKGROUND Atopy patch testing (APT) has shown potential for predicting dietary food triggers in studies of children and adolescents with eosinophilic esophagitis (EoE). AIMS To assess the efficacy of APT in adults with EoE. METHODS We conducted a prospective open-label pilot study of patients ≥ 18 years old with diagnosis of EoE at Mayo Clinic in Rochester, Minnesota, from November 2014 to January 2016. All patients underwent patch testing using intact food products, followed by a six food elimination diet and stepwise food reintroduction. Response to elimination diet was assessed with serial endoscopy with biopsies as well as clinical symptoms. APT results were directly compared to elimination diet results for assessment of efficacy. Correlation between clinical symptoms, endoscopic score, and histology was also qualitatively evaluated. RESULTS Fifty percent of the patients had a positive APT, while only 16% had an APT result confirmed histologically during food reintroduction. Sensitivity of APT was calculated to be 5.9%, with specificity of 92.0%. Furthermore, we found significant qualitative inter-patient heterogeneity in the correlation between clinical symptoms, EREFS score, and histology. CONCLUSIONS APT does not reliably predict food triggers identified by food elimination diet in adult patients with EoE. As a result, APT does not have a clear role in the evaluation of patients with EoE.

Ankylosaurus back sign: novel endoscopic finding in esophageal eosinophilia patients indicating proton pump inhibitor response. Endosc Int Open 2018; 6:E165-E172.

Abstract
BACKGROUND AND STUDY AIMS Characteristic endoscopic findings, such as linear furrows, rings, and whitish exudates, indicate the presence of esophageal eosinophilia (EE), though no specific findings are known to distinguish eosinophilic esophagitis (EoE) from proton pump inhibitor-responsive esophageal eosinophilia (PPI-REE). Here, we present a novel endoscopic finding in some EE patients possessing a linear longitudinal arrangement of whitish nodules with the appearance of the back of an Ankylosaurus dinosaur, termed Ankylosaurus back sign (ABS), and evaluations of its significance in affected patients. PATIENTS AND METHODS Fifty-five patients diagnosed with EE (≥ 15 eosinophils/high power field) who were treated at our hospital and shown to evaluate a PPI response were enrolled. Endoscopic findings at baseline and clinical parameters were retrospectively reviewed. Furthermore, the clinicopathological features of patients with ABS, as well as the relationship between its presence and PPI response were evaluated. RESULTS Fifty-five patients (47 males, 8 females) with EE (17 with EoE, 38 with PPI-REE) were evaluated, of whom 50 (90.9 %) had linear furrows, the most frequently found feature, while ABS was found in 9 (16.4 %). Inter-observer agreement was substantial for ABS (κ 0.77). Interestingly, all patients with ABS had PPI-REE. Our findings revealed that the presence of ABS was closely associated with reflux esophagitis (RE) in patients with PPI-REE. CONCLUSIONS Although ABS was less frequent than typical endoscopic findings such as linear furrows in EE, this novel finding was closely associated with PPI-REE accompanied with RE. The clinical implications of ABS in patients with EE should be investigated further.

Abstract
Eosinophilic esophagitis (EoE) is a new disease. It is caused by a T-helper type 2 cell response to food antigens in contact with the esophageal mucosa. Although no single feature defines EoE, a constellation of compatible demographic, clinical, endoscopic, and histologic findings establish the diagnosis. Children present with symptoms and endoscopic patterns characteristic of inflammation, whereas adolescents and adults have manifestations of fibrosis and gross esophageal strictures. Clinical and endoscopic scoring systems have helped to standardize diagnosis. There is controversy in EoE research over the optimal endpoint for treatment. Although the most common endpoint is a reduced number of eosinophils in biopsies, changes in symptoms and endoscopic features are becoming important targets of therapy. We should improve our understanding of EoE progression and the need for maintenance therapy, and continue development of diagnostic tools that avoid endoscopy and biopsy analyses to more easily monitor disease activity.

Abstract
Eosinophilic esophagitis (EoE) was first described by Landis in 1978. The disease is characterized by esophageal symptoms, primarily dysphagia in adult patients, and esophageal eosinophilic infiltration. The disease is associated with characteristic endoscopic findings, including edema, rings, furrows, exudates, and strictures. The typical radiographic findings of this disorder are rings, strictures, and small-caliber esophagus. The endoscopic and radiographic findings of EoE are the topic of this review.

Abstract
Eosinophilic esophagitis (EoE) has arisen as a common disorder in current clinical and endoscopic gastroenterology practice. Areas covered: A comprehensive review of the literature to summarize and update different aspects related with the use of endoscopy in the diagnostic workout and treatment of pediatric and adult EoE patients is conducted. Expert commentary: Endoscopic features in EoE are frequently subtle, so were inadverted in some initial reports of the disease. Literature has described a wide number of EoE-associated features, systematized in the EREFS classification, which standardized the grade and severity of exudates, rings, edema, furrows, and strictures. The insufficient reliability of these features to predict eosinophilic inflammation still makes biopsies essential in diagnosing or monitoring EoE. EoE causes half of the food impactions requiring endoscopy; food impaction leads to EoE diagnosis in up to half of cases. Long term consequences of EoE include esophageal remodeling leading to strictures and narrowing, thus impairing symptoms and needs dilation. Recognizing the risks from dilation in EoE required carrying out a safe technique to avoid the high complication rate reported in the early literature. Endoscopic dilation should be considered in patients with esophageal narrowing and dysphagia/food impaction unresponsive to diet or drugs-based anti-inflammatory treatment.

Abstract
BACKGROUND & AIMS A 6-food elimination diet induces remission in most children and adults with eosinophilic esophagitis (EoE). The effectiveness of empiric elimination of only 4 foods has not been studied in children. We performed a prospective observational outcome study in children with EoE treated with dietary exclusion of cow's milk, wheat, egg, and soy. The objective was to assess the clinical, endoscopic, and histologic efficacy of this treatment in EoE. METHODS We recruited children (1-18 years old, diagnosed per consensus guidelines) from 4 medical centers. Study participants (n = 78) were given a proton pump inhibitor twice daily and underwent a baseline esophagogastroduodenoscopy. Subjects were instructed on dietary exclusion of cow's milk, wheat, egg, and soy. Clinical, endoscopic, and histologic assessments were made after 8 weeks. Responders had single foods reintroduced for 8 weeks, with repeat endoscopy to assess for recurrence of active disease. The primary endpoint was histologic remission (fewer than 15 eosinophils per high-powered field). Secondary endpoints included symptom and endoscopic improvements and identification of foods associated with active histologic disease. RESULTS After 8 weeks on 4-food elimination diet, 50 subjects were in histologic remission (64%). The subjects' mean baseline clinical symptoms score was 4.5, which decreased to 2.3 after 8 weeks of 4-food elimination diet (P < .001). The mean endoscopic baseline score was 2.1, which decreased to 1.3 (P < .001). After food reintroduction, the most common food triggers that induced histologic inflammation were cow's milk (85%), egg (35%), wheat (33%), and soy (19%). One food trigger that induced recurrence of esophageal inflammation was identified in 62% of patients and cow's milk-induced EoE was present in 88% of these patients. CONCLUSIONS In a prospective study of children with EoE, 8 weeks of 4-food elimination diet induced clinical, endoscopic, and histologic remission in more than 60% of children with EoE. Although less restrictive than 6-food elimination diet, 4-food elimination diet was nearly as effective, and can be recommended as a treatment for children with EoE.

Abstract
OBJECTIVES There is no clear consensus regarding the most appropriate measure(s) of eosinophilic esophagitis (EoE) disease activity. We aimed to identify all scoring indices used for the measurement of disease activity in EoE, appraise their operating properties, and discuss their value as outcome measures. METHODS MEDLINE, EMBASE, and CENTRAL (The Cochrane library) were searched from inception to 11 May 2016. Randomized controlled trials (RCTs), cohort, case-control, and cross-sectional studies that reported outcomes to measure EoE disease activity or response to treatment were eligible. Operating properties of histologic, endoscopic, and patient reported/symptomatic and health-related quality of life measures were critically appraised according to guidelines proposed by the United States Food and Drug Administration. RESULTS Of 4,373 citations, 130 studies were eligible, of which 20 were RCTs. Although no index met all evaluative criteria, we found that: (1) the EoE histologic scoring system (EoEHSS) is the most valid histologic measure; (2) the Endoscopic Reference Score (EREFS) is the most reliable and responsive endoscopy measure; and (3) the Eosinophilic Esophagitis Activity Index (EEsAI) or the Dysphagia Symptoms Questionnaire (DSQ) had superior construct validity and responsiveness in adults. The Pediatric Quality of Life Inventory EoE was the most valid pediatric symptomatic measure. CONCLUSIONS Current evidence supports the use of the EoEHSS and EREFS as measures of histologic and endoscopic EoE disease activity, respectively, and the EEsAI, DSQ, or Pediatric Quality of Life Inventory EoE as measures of adult and pediatric symptoms. Additional research is needed to optimize endpoint configuration to facilitate development of new therapies.

Abstract
The study by Greuter et al. entitled "Long-term treatment of eosinophilic esophagitis and swallowed topical corticosteroids: development and evaluation of a therapeutic concept" follows 351 patients over 6 years. This gives considerable insight into long-term topical steroid management of EoE and establishes the concept of deep remission in EoE.

Abstract
Over the past decades eosinophilic esophagitis (EoE) has been increasingly diagnosed, and significant progress has been made in our understanding of its pathophysiology. As EoE cannot be cured yet, treatment goals are suppression of disease activity and symptoms as well as the prevention of progression to a more severe disease phenotype. Disease-modifying treatment options can be divided into dietary therapy and immunosuppressive medications, of which topical steroids have been most investigated, yet are still prescribed off-label. In this review, we will summarize recent advances in our understanding of EoE and discuss the mechanisms of action of current treatment options, with emphasis on the role of the esophageal epithelial barrier and the effects of proton-pump inhibitors in the management of patients with EoE.
