Abstract
OBJECTIVE To describe the prevalence of laryngopharyngeal reflux (LPR)-related symptoms in allergy patient using the Reflux Symptom Index (RSI) by Belafsky et al and the Reflux Symptom Score (RSS) by Lechien et al. SUBJECTS AND METHODS: A total of 84 patients were enrolled in this study. Fifty-two consecutive patients were asked to fill RSI. Similarly, 32 patients were asked to fill RSS. Demographic data included age, gender, history of smoking, family history for eczema, atopy, asthma, food and drug allergy. RESULTS Fifty-seven of the 84 patients were positive for at least one allergen and hence were diagnosed with allergy. Of the 52 patients who received the RSI, 36 patients were allergic to at least one allergen (36/52). Of the 32 patients who filled the RSS, 21 tested positive for at least one allergen (21/32). There was no significant difference in the number of positive RSI scores (>13) between patients with allergy to at least one allergen in comparison to patients with no allergy (P = 0.329). There was a significant difference in the number of positive RSS scores (>13) between patients with allergy to at least one allergen in comparison to patients with no allergy (P-value 0.0345). The odds of having RSS >13 in an allergic patient was significant (OR = 5.6, CI 95% = 1.15-27.37). CONCLUSION The results of this study provide evidence that patients with allergy have increased incidence of LPR related symptoms using the RSS. The cross-cutting in the clinical picture of patients with allergy and LPR stresses the need for objective testing such as double probe Ph-metry and impedance to diagnose this latter. Future studies are needed to explore further the cause-effect relationship between allergy and LPR.

Abstract
This study is to evaluate the feasibility of deep learning (DL) models in the multiclassification of reflux esophagitis (RE) endoscopic images, according to the Los Angeles (LA) classification for the first time. The images were divided into three groups, namely, normal, LA classification A + B, and LA C + D. The images from the HyperKvasir dataset and Suzhou hospital were divided into the training and validation datasets as a ratio of 4 : 1, while the images from Jintan hospital were the independent test set. The CNNs- or Transformer-architectures models (MobileNet, ResNet, Xception, EfficientNet, ViT, and ConvMixer) were transfer learning via Keras. The visualization of the models was proposed using Gradient-weighted Class Activation Mapping (Grad-CAM). Both in the validation set and the test set, the EfficientNet model showed the best performance as follows: accuracy (0.962 and 0.957), recall for LA A + B (0.970 and 0.925) and LA C + D (0.922 and 0.930), Marco-recall (0.946 and 0.928), Matthew's correlation coefficient (0.936 and 0.884), and Cohen's kappa (0.910 and 0.850), which was better than the other models and the endoscopists. According to the EfficientNet model, the Grad-CAM was plotted and highlighted the target lesions on the original images. This study developed a series of DL-based computer vision models with the interpretable Grad-CAM to evaluate the feasibility in the multiclassification of RE endoscopic images. It firstly suggests that DL-based classifiers show promise in the endoscopic diagnosis of esophagitis.

Abstract
BACKGROUND Thickening of the esophageal wall in patients with eosinophilic esophagitis (EoE) and gastro-esophageal reflux disease (GERD) has been shown in studies using endoscopic ultrasound (EUS). We hypothesise that transmural inflammation in EoE results in prominent esophageal wall thickening compared with the mucosal inflammation in GERD. The aim of this study was to compare the relationship among dysphagia, endoscopic appearance, wall thickness, histology, and motility in EoE and GORD. METHODS EoE and GERD patients were prospectively studied between February 2012 and April 2021. Patients were studied on 2 separate occasions with endoscopy, EUS and mucosal biopsies, followed by high-resolution manometry. Epidemiology and dysphagia data were obtained. RESULTS A total of 45 patients (31 EoE, 14 GERD) were included. There were no significant differences in age, sex, duration of disease and presence of esophageal motility disorders. EoE patients had a higher dysphagia score (P < 0.001), EREFS score (P < 0.001) and peak eosinophil count (P < 0.001) compared with GERD patients. Thickness of the submucosa in the distal esophagus in EoE was significantly higher than GERD (P = 0.003) and positively correlated with duration of disease (P = 0.01, R = 0.67). Positive correlation was also found between dysphagia score and distal total esophageal wall thickness (P = 0.03, R = 0.39) in EoE patients. No correlation was found between these variables in GERD patients. CONCLUSION Distal esophageal wall thickness positively correlates with dysphagia score in EoE but not GERD. This appears to be related to the composition of the submucosa which can be identified using EUS.

Abstract
BACKGROUND Limited data are available to support current guidelines recommendations on obtaining gastric and duodenal biopsies of patients with clinical and histologic manifestations consistent with eosinophilic esophagitis (EoE) to rule out eosinophilic gastritis (EG) or duodenitis (EoD). Our study examined the prevalence of concomitant extraesophageal, gastrointestinal pathology to better characterize the diagnostic yield of additional biopsies. METHODS This was a single-center, retrospective study which utilized ICD 9 codes (530.13) and search queries of pathology reports ("Eosinophilic esophagitis," "EoE") to identify EoE patients. Patient endoscopy reports, pathology reports, and office notes were manually reviewed to characterize cases. RESULTS The electronic health record search yielded 1,688 EoE adults. In those who had extra-esophageal biopsies obtained, EG was identified in 34 (3.4%), H. pylori in 45 (4.6%), EoD in 27 (3.3%), and histology consistent with celiac disease in 20 (2.5%). Endoscopic abnormalities were found in the stomach of 92% of patients with EoE and EG and in the duodenum of 50% of patients with EoE and EoD. Symptoms of dyspepsia and/or abdominal pain occurred in a significantly greater proportion of patients with extraesophageal disease (64% vs. 19% in EoE group, p < 0.001). Overall, extraesophageal pathology would have been missed in 1.4% of patients lacking either symptoms or endoscopic signs suggestive of extraesophageal disease. CONCLUSIONS The yield of gastric and duodenal biopsies in adults with EoE is low, with 6.5% of patients demonstrating histologic features of celiac disease, Helicobacter pylori, EG, and/or EoD. Biopsies of extraesophageal, gastrointestinal sites in patients with suspected or previously diagnosed EoE should consider symptom and endoscopy manifestations as well as the potential impact of histopathologic findings on clinical management.

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
Innovations in endoscopy have brought about some impressive improvements in diagnosing and treating gastroesophageal reflux disease (GERD). GERD, as one of the most prevalent gastrointestinal disorders in the world, has always been on the cutting edge of endoscopic interventions. A primary diagnosis of GERD is based on symptoms and an initial trial of proton-pump inhibitor (PPI) therapy, which is devoid of adequately instructive value for therapeutic strategies. Endoscopy and optional biopsies can be used to directly observe and determine the abnormal structural and pathophysiological damage in the esophagus. The emergence of minimally invasive endoscopic therapy fills the gap between patients who are reluctant or insensitive to PPIs and candidates who are not indicated for surgical anti-reflux fundoplication. In this review, we discuss the utility of endoscopy and biopsy in patients with persistent GERD-related manifestations after proper medical anti-reflux treatment. Moreover, we portray a landscape of four current endoscopic GERD therapies and clarify the merits and disadvantages of each technique. Future research needs to concentrate on stratifying GERD patients based on personal conditions and elucidating the primary pathophysiology of GERD.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is an immune-mediated clinicopathological condition characterized by esophageal infiltration with eosinophils resulting in chronic inflammation and stricture. SUMMARY The recent increase in the incidence of EoE and the characteristic presentation of symptoms with difficulty swallowing and food bolus impaction has raised key concerns of clinicians as well as researchers. EoE often presents with dysphagia, food impaction, nausea, regurgitation or vomiting, and decreased appetite. It is more common in males, affecting both adults and children. The causative manner of this condition is complex and multifactorial. Throughout recent years, researchers have made a significant contribution to understanding the pathogenesis of EoE, genetic background, natural history, work on allergy, and standardization in the evaluation of disease activity. There is relatively high prevalence of EoE among the population, emphasizing the importance of this disease. Key messages: Esophageal involvement with eosinophils may be manifested as isolated or with coexisting conditions and should be taken into consideration in the differential diagnosis. This study aimed to provide gastroenterologists with novel insights into the evaluation of esophageal involvement with eosinophils and to pay special attention to the etiological factors, coexisting clinical diseases, and complications.

Abstract
The cause of eosinophilic esophagitis (EoE) is not well understood. Most patients with EoE have allergic disorders. Here, we describe a patient with gastroesophageal reflux and EoE with dysphagia, substernal discomfort and retrosternal pain. Based on symptomatology consistent with gastroesophageal reflux disease (GERD), treatment started with proton pump inhibitors (PPIs) but no effect was observed. Next, the patient underwent esophagogastroduodenoscopy and multiple biopsies were acquired from the lower and upper esophagus. Cortisone treatment was given and high-resolution manometry was performed before and after treatment. The results suggested that esophageal motility improved after cortisone therapy together with improvements in the clinical and histological pictures.

Eosinophilic esophagitis (EoE) is often misdiagnosed as GERD; therefore, the goal of the current study is to establish a non-invasive diagnostic and monitoring biomarker that differentiated GERD from EoE. Reports indicates that IL-15 responsive iNKT cells and tissue specific IgE have a critical in EoE pathogenesis, not in GERD. Therefore, we tested the hypothesis that the panel of IL-15-responsive T cell and IgE receptors may be novel non-invasive biomarkers for EoE. Accordingly, the receptors of IL-15 responsive T cells (Vα24, Jα18, γδT, αβT) and IgE (FcεRI & FcεRII) were examined. The data indicates that blood mRNA levels of Vα24, Jα18, γδ T, αβ T and FcεRI are significantly reduced in EoE compared to the GERD patients and normal individuals. The ROC curve analysis indicated FcεRII, Jα18 and δ TCR are the positive predictors that discriminate EoE from GERD. Thus, these molecules will be a novel non-invasive diagnostic biomarker for EoE.

Intestinal eosinophils: multifaceted roles in tissue homeostasis and disease. Semin Immunopathol 2021; 43:307-317.

Abstract
Intestinal eosinophils are largely considered to be one of the central immune effector cells during helminth infection and disorders such as eosinophilic oesophagitis and food allergies. Given the abundance of these cells present in the gastrointestinal tract at homeostasis, emerging studies now reveal novel roles for eosinophils in the development and regulation of immunity, and during tissue repair. In addition, the identification of distinct eosinophil subsets indicates that we must consider the heterogeneity of these cells and how they differentially participate in mucosal immunity at steady state and during disease. Here, we summarise the literature on intestinal eosinophils, and how they contribute to mucosal homeostasis through immune regulation and interactions with the microbiome. We then explore the divergent roles of eosinophils in the context of eosinophilic gastrointestinal disorders and during helminth infection, whereby we discuss key observations and differences that have emerged from animal models and human studies. Lastly, we consider the possible interactions of eosinophils with the enteric nervous system, and how this represents an exciting area for future research which may inform future therapeutic targets.

Abstract
Eosinophilic esophagitis (EoE) is a relatively recently identified but now frequently encountered antigen/immune-mediated disease which places significant burden on patients and the healthcare system. With its growing prevalence and recognition by healthcare providers in multiple disciplines, substantial progress has been made regarding the diagnostic criteria, clinical evaluation, tools for disease assessment, and immune pathways related to pathogenesis. Current treatment goals focus on the amelioration of inflammation and prevention of remodeling consequences using proton pump inhibitors, swallowed topical steroids, elimination diets, and esophageal dilation. Ongoing research holds promise for more efficacious and targeted therapies as well as a personalized approach to the care of patients with EoE.

Abstract
Background: An increase in the incidence of eosinophilic esophagitis worldwide is being observed in children. The aim of the study was to analyze the incidence, clinical manifestations, biochemical markers and endoscopic features of children with eosinophilic esophagitis in comparison to patients with non-eosinophilic esophagitis. Methods: This single-center retrospective study included newly diagnosed children with eosinophilic (EoE) and non-eosinophilic (non-EoE) esophagitis based on endoscopic and histopathological results between January 2013 and December 2018. Result: Among 433 of enrolled children with esophagitis, 36 (8.31%) were diagnosed with EoE (median age of 10 years). Male predominance and an increased percentage of allergy cases in the EoE group were noticed. Dysphagia was the only symptom that significantly differentiated both groups (p = 0.006). Endoscopic findings with relevant relationships with EoE included linear fissuring, decreased vascular pattern, trachealization and whitish exudates. No significant difference in the prevalence of other reported diseases between groups was observed. Conclusion: The results of EoE analysis in children from North-Eastern Poland did not differ from reports from other countries. The reported symptoms were not specific for EoE, and only dysphagia and some endoscopic lesions were helpful to differentiate children with EoE from non-EoE.

Abstract
BACKGROUND AND AIMS Treatment paradigms for proton pump inhibitors (PPIs) in eosinophilic esophagitis (EoE) are evolving. We aimed to determine patterns of long-term PPI use after EoE diagnosis in PPI histologic non-responders. METHODS We conducted a retrospective review at University of Colorado (UCH) and University of North Carolina (UNC) of EoE patients who were histologic non-responders to PPIs. Data were extracted from electronic medical records related to demographics, PPI use, and reasons for continuing or stopping PPI. RESULTS Of 67 patients in the UCH cohort, PPIs were initially discontinued in 9 (13%). Of 58 remaining on PPI, 48% were not instructed to discontinue therapy and 26% continued for symptom improvement. Of 675 patients at UNC, PPI was stopped in 185 (27%). Of patients remaining on PPI, 15% were not told to discontinue therapy and 62% were continued for symptom improvement. At last contact, >50% of patients remained on PPI at both centres with most common reasons for continuation being symptom improvement and not telling patients to discontinue. In the UNC cohort, clinical features associated with remaining on PPI included children younger than 18 years (p=0.01), males (p<0.001), heartburn symptoms (p<0.001) and hiatal hernia (p=0.004). Patients with dysphagia were less likely to remain on PPIs (p<0.001). CONCLUSIONS Long-term PPI use is common in EoE patients even without histologic response. Failure to instruct patients to discontinue therapy was a common reason for long-term use, thus PPI use should be revisited in all EoE patients to confirm clinical benefit.

Abstract
INTRODUCTION Eosinophilic Esophagitis (EoE) is an immune-mediated, chronic inflammatory disorder of the esophagus. Topical steroids have been used in the management of EoE for over 15 years. However, there are no Food and Drug Administration (FDA) approved drug therapies for EoE. AREAS COVERED This review discusses the current understanding of EoE and the role of topical steroids in the induction and maintenance of remission in patients with EoE. We performed a comprehensive review of the literature, summarized randomized control trials from 2006 to 2020, and provided a simplified management algorithm for EoE. EXPERT OPINION In patients with EoE, topical steroids are effective in inducing clinical and histologic remission. Formulations of topical steroids that maximize the exposure to esophageal mucosa have the highest efficacy. A majority of patients who achieve remission with topical steroids develop clinical and histologic relapse off therapy within a year. Current evidence suggests that maintenance therapy with long-term topical steroids decreases the risk of relapse and progression to fibrostenotic disease. While uncertainty over the dose and duration of maintenance topical steroids and their potential side effects exists, long-term maintenance therapy with topical steroids appears to be the way forward to improve long-term outcomes in patients with 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
Background and Aim Eosinophilic esophagitis (EoE) and gastroesophageal reflux disease (GERD) can be difficult to distinguish as many of their clinical and histological features overlap. Preliminary data suggest a potential association between EoE and immunoglobulin G4 (IgG4) but not GERD. This study aimed to examine the role of esophageal mucosal IgG4 staining when differentiating EoE from GERD. Methods Esophageal biopsy specimens from patients with proven EoE and GERD were evaluated, and immunohistochemical staining for IgG4 was performed by an experienced gastrointestinal pathologist blinded to the clinical and endoscopic data. The results on IgG4 staining were then correlated with clinical, endoscopic, and histological features. Results Sixty patients were included in the study, with 30 EoE (38.8 ± 12.8 years, 23 M:7 F) and 30 GERD (50.7 ± 14.3 years, 14 M:16 F) patients. The prevalence of a positive intercellular IgG4 stain was significantly higher in the EoE patients than those with GERD (23/29 vs 2/30; P < 0.0001). Positive IgG4 stain had the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 77%, 93%, 92%, and 80% for predicting the diagnosis of EoE, respectively. In both EoE and GERD patients, correlation was found between positive IgG4 staining and food bolus obstruction, dysphagia to solids, reflux, fixed rings, Barrett's esophagus, hiatus hernia, and esophagitis. In EoE patients, positive IgG4 staining was not correlated with the type of symptoms, endoscopic findings, histological findings, proton pump inhibitor therapy, or history of allergy/atopy. Conclusion Given the high specificity and PPV of positive IgG4 staining in esophageal biopsies for EoE, this can be a useful marker to distinguish the disease from GERD.

Abstract
Eosinophilic gastrointestinal disorders (EGID) are a group of disorders characterized by pathologic eosinophilic infiltration of the esophagus, stomach, small intestine, or colon leading to organ dysfunction and clinical symptoms (J Pediatr Gastroenterol Nutr; Spergel et al., 52: 300-306, 2011). These disorders include eosinophilic esophagitis (EoE), eosinophilic gastritis (EG), eosinophilic gastroenteritis (EGE), eosinophilic enteritis (EE), and eosinophilic colitis (EC). Symptoms are dependent not only on the location (organ) as well as extent (layer invasion of the bowel wall). Common symptoms of EoE include dysphagia and food impaction in adults and heartburn, abdominal pain, and vomiting in children. Common symptoms of the other EGIDs include abdominal pain, nausea, vomiting, early satiety, diarrhea, and weight loss. These disorders are considered immune-mediated chronic inflammatory disorders with strong links to food allergen triggers. Treatment strategies focus on either medical or dietary therapy. These options include not only controlling symptoms and bowel inflammation but also on identifying potential food triggers. This chapter will focus on the clinical presentation, pathophysiology, and treatment of these increasingly recognized disorders.

Abstract
Esophageal diseases result in significant mortality, morbidity, and health care costs worldwide. Current approaches to detect and monitor esophageal diseases have severe limitations. Advanced imaging technologies are being developed to complement current approaches to improve diagnostic, therapeutic and surveillance protocols in order to advance the field. Raman spectroscopy-based technologies hold promise to increase the sensitivity for detection of diseased and high-risk lesions in vitro and in vivo in real time. This technique allows for the investigation of microstructural changes and also facilitates the discovery of disease-specific biochemical alterations with the potential to provide novel insights into the pathobiology of these conditions. Raman spectroscopy has been increasingly applied in precancerous and cancerous esophageal conditions. However, its application in benign esophageal diseases is still in the early stages. Continuing its application in cancerous and precancerous conditions and expanding its use to benign esophageal disorders could lay a foundation for integration of this technology in clinical practice and diagnostic paradigms and development of an accurate and cost-effective tool for use in a clinical setting. Furthermore, Raman spectroscopy can also be used as an innovative technique to advance our understanding of the biochemical transformations associated with esophageal diseases and answer a myriad of fundamental questions in the field. In this review, we described the principles of Raman spectroscopy and instrumentation while providing an overview of current applications, challenges, and future directions in the context of esophageal diseases with an emphasis on its clinical translational application.

Abstract
BACKGROUND Esophageal eosinophilia (EE) is a basal condition of eosinophilic esophageal disorders including eosinophilic esophagitis (EoE) and asymptomatic EE. EoE is considered as an allergic disorder, while it is unclear whether other non-allergic conditions are involved in the pathophysiology of EE. The aim of this study is to investigate the non-allergic risk factors for EE. METHODS This cross-sectional study included subjects who underwent esophagogastroduodenoscopy on a medical health check-up. We compared clinical characteristics between subjects with EE (n = 27) and those without EE (n = 5937). RESULTS The detection rate of EE was 0.45% (27/5964 persons). Of 27 subjects with EE, 20 subjects were symptomatic and 7 were asymptomatic. On univariate analysis, subjects with EE significantly had higher body mass index (BMI) compared to those without EE; 23.4 (4.4) vs 22.3 (4.5) kg/m2, median (interquartile range), p = 0.005. Endoscopic findings revealed that subjects with EE had significantly higher proportion of hiatal hernia (29.6% vs 14.7%; p = 0.049). Subjects with EE were significantly younger and had higher proportion of bronchial asthma; 45 (11.5) vs 51 (18) years, p = 0.013; 25.9% vs 5.2%, p < 0.001, respectively. Multivariate analysis showed that subjects with EE were positively associated with BMI [odds ratio (OR) 1.11; 95% confidence interval (CI) 1.03-1.20; p = 0.010) and hiatal hernia (OR 2.63; 95% CI 1.12-6.18; p = 0.026) compared to those without EE. On trend test, advanced BMI classification had significant trend for increased prevalence of EE (p = 0.002). CONCLUSIONS Obesity and hiatal hernia may be non-allergic risk factors for EE in Japanese adults.

Abstract
AIM Children with severe uncontrolled asthma (SUA) have a high burden of symptoms and increased frequency of asthma exacerbations. Reflux esophagitis and eosinophilic esophagitis are important co-morbid factors for SUA. Both are associated with the presence of eosinophils in esophageal mucosa. We hypothesized that esophageal eosinophils are frequently present and correlate with the presence of airway eosinophils in children with SUA. METHOD We performed a retrospective analysis of a prospective database of children who underwent "triple endoscopy" (sleep laryngoscopy, bronchoscopy with bronchoalveolar lavage [BAL] and endobronchial biopsy [EBB], and esophagogastroduodenoscopy with esophageal biopsy [EsB]) at our Aerodigestive Center for evaluation of SUA. Children with known cystic fibrosis, primary ciliary dyskinesia, and aspiration-related lung disease were excluded. RESULT Twenty-four children (21 males) ages 2-16 years were studied. Elevated BAL eosinophils were found in 10 (42%) patients, endobronchial eosinophils in 16 (67%); 7 (29%) had endobronchial eosinophils without elevated BAL eosinophils. Esophageal eosinophils were found in 11 (46%) patients. There was a correlation between the amount of eosinophils in BAL and EBB (R = 0.43, P = 0.05) airway eosinophils, defined as elevated BAL and/or EBB eosinophils, correlated with esophageal eosinophils (R = 0.41, P = 0.047). CONCLUSION We concluded that airway and esophageal eosinophils are frequently present in children with SUA.

Abstract
Eosinophilic oesophagitis (EoE) and gastro-oesophageal reflux disease (GORD) are the most common causes of chronic oesophagitis and dysphagia associated with oesophageal mucosal eosinophilia. Distinguishing between the two is imperative but challenging due to overlapping clinical and histological features. A diagnosis of EoE requires clinical, histological and endoscopic correlation whereas a diagnosis of GORD is mainly clinical without the need for other investigations. Both entities may exhibit oesophageal eosinophilia at a similar level making a histological distinction between them difficult. Although the term proton-pump inhibitor responsive oesophageal eosinophilia has recently been retracted from the guidelines, a relationship between EoE and GORD still exists. This relationship is complex as they may coexist, either interacting bidirectionally or are unrelated. This review aims to outline the differences and potential relationship between the two conditions, with specific focus on histology, immunology, pathogenesis and treatment.

Eosinophilic Esophagitis: Review and Update. Front Med (Lausanne) 2018; 5:247. [PMID: 30364207 PMCID: PMC6192373 DOI: 10.3389/fmed.2018.00247] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Accepted: 08/15/2018] [Indexed: 12/13/2022] Open
Abstract
Background: Eosinophilic esophagitis (EoE) was first described in the 1990s, showing an increasing incidence and prevalence since then, being the leading cause of food impaction and the major cause of dysphagia. Probably, in a few years, EoE may no longer be considered a rare disease. Methods: This article discusses new aspects of the pathogenesis, symptoms, diagnosis, and treatment of EoE according to the last published guidelines. Results: The epidemiological studies indicate a multifactorial origin for EoE, where environmental and genetic factors take part. EoE affects both children and adults and it is frequently associated with atopic disease and IgE-mediated food allergies. In patients undergoing oral immunotherapy for desensitization from IgE-mediated food allergy the risk of developing EoE is 2.72%. Barrier dysfunction and T-helper 2 inflammation is considered to be pathogenetically important factors. There are different patterns of clinical presentation varying with age and can be masked by adaptation habits. Besides, symptoms do not usually correlate with histologic disease activity. The diagnostic criteria for EoE has evolved but mainly requires symptoms of esophageal dysfunction with histologic evidence of a peak value of at least 15 eosinophils per high-power field. Endoscopies have to be repeated in order to diagnose, monitor, and treat EoE. Treatment of EoE can be started either by drugs (PPIs and topical corticosteroids) or elimination diets. The multistage step-up elimination diet management approach of EoE is promising. Endoscopic dilation is used for patients with severe dysphagia/food impaction with inadequate response to anti-inflammatory treatment. Conclusions: Research in recent years has contributed to a better understanding of EoE's pathogenesis, genetic background, natural history, allergy workup, standardization in assessment of disease activity, evaluation of minimally invasive diagnostic tools, and new therapeutic approaches. However, several unmet needs are to be solved urgently, as finding a non-invasive disease-monitoring methods and biomarkers for routine practice, the development or new therapies, novel food allergy testing to detect triggering foods, drug, and doses required for initial therapy and safety issues with long-term maintenance therapy, amongst others. Besides, multidisciplinary management units of EoE, involving gastroenterologists, pediatricians, allergists, pathologists, dietitians, and ENT specialists are needed.

Abstract
BACKGROUND AND AIM Esophagogastric junction outflow obstruction (EGJOO) may be due to anatomical abnormalities, but it is unclear how to evaluate them after high-resolution manometry. We aimed to determine (i) clinical and high-resolution manometry parameters differentiating anatomical EGJOO from functional EGJOO, (ii) investigations chosen and yield for anatomical EGJOO, and (iii) clinical outcomes of functional EGJOO. METHODS Medical records of consecutive patients with symptomatic EGJOO from February 2012 to December 2015 were reviewed. EGJOO was defined as anatomical if investigations identified a macroscopic or microscopic pathology accounting for EGJOO. RESULTS Forty of 292 (13.7%) had EGJOO, of which 6/40 (15%) had anatomical EGJOO (two PPI-responsive esophageal eosinophilia, two infiltrating cancers, and two external compressions). Anatomical EGJOO was more likely to present with dysphagia (100% vs 29.4%, P = 0.001) and less likely with regurgitation (0% vs 41.2%, P = 0.05). Anatomical EGJOO had higher frequencies of premature contraction (50% vs 5.9%, P = 0.003) and lower mean values of distal latency (5.6 +/- 1.3 vs 6.7 +/- 1.2, P = 0.004). Computed tomography scans revealed 50% (3/6) of etiologies of anatomical EGJOO. Approximately, 73.5% (25/34) of patients with functional EGJOO had spontaneous resolution of their symptoms. One underwent pneumatic dilatation with symptom resolution while remaining eight with persistent symptoms were attributed to gastroesophageal reflux disease. CONCLUSION Anatomical causes are present in 15% of EGJOO. Evaluation is warranted especially in patients presenting with dysphagia. Esophageal biopsies, barium swallows, computed tomography scans, and endoscopic ultrasound are complementary in EGJOO evaluation. In patients with non-obstructive symptoms and no anatomical etiologies, monitoring for spontaneous resolution is an option.

Abstract
A significant percentage of patients with gastroesophageal reflux disease (GERD) will not respond to proton pump inhibitor (PPI) therapy. The causes of PPI-refractory GERD are numerous and diverse, and include adherence, persistent acid, functional disorders, nonacid reflux, and PPI bioavailability. The evaluation should start with a symptom assessment and may progress to imaging, endoscopy, and monitoring of esophageal pH, impedance, and bilirubin. There are a variety of pharmacologic and procedural interventions that should be selected based on the underlying mechanism of PPI failure. Pharmacologic treatments can include antacids, prokinetics, alginates, bile acid binders, reflux inhibitors, and antidepressants. Procedural options include laparoscopic fundoplication and LINX as well as endoscopic procedures, such as transoral incisionless fundoplication and Stretta. Several alternative and complementary treatments of possible benefit also exist.

Abstract
PURPOSE OF REVIEW Eosinophilic esophagitis (EoE) has transformed over the past two decades from a little-known entity to a significant cause of morbidity in the adult and pediatric population. We reviewed the most recent advancements in the diagnosis, therapy, and long-term monitoring of EoE. RECENT FINDINGS Based on clinical, endoscopic, histologic, immunologic, and genetic similarities, there is growing consensus to move away from distinguishing proton pump inhibitor responsive esophageal eosinophilia as an entity distinct from EoE. An increasing number of studies have identified duration of untreated disease as an important determinant of esophageal stricture formation. New approaches to the empiric elimination diet including one, two, four, and step-up protocols were developed to reduce the need for repeated endoscopies during reintroduction of food triggers. Topical steroids remain the mainstay of medical therapy but newer formulations are under development to optimize esophageal delivery. Novel, disease activity monitoring techniques are being evaluated that assess esophageal inflammatory activity without the need for endoscopy. Understanding of EoE has increased remarkably from the first identification of the disease. The underlying pathogenesis continues to be explored leading to shifts in diagnostic criteria as well as novel therapeutic targets. Innovative methods to monitor disease are under investigation and more research is needed to understand the natural history of EoE.

Abstract
Eosinophilic esophagitis advances parallel the increased prevalence. Developments include refining the diagnostic criteria, identifying risk factors, appreciating the contribution of inflammatory pathways, recognizing the importance of subepithelial remodeling, validating trial endpoints, defining a role for biological therapies, and optimizing dietary therapy. Endoscopic outcomes have emerged as endpoints in trials of novel therapeutics. Expanding efforts seek to develop less-invasive methods to assess disease activity thereby reducing the burden of repeated endoscopic procedures during elimination diets. The functional lumen imaging probe is now identified as a determinant of complications with potential utility as a therapeutic endpoint.

Abstract
Gastroesophageal reflux disease (GERD) is the most prevalent gastrointestinal disorder in the United States, and leads to substantial morbidity, though associated mortality is rare. The prevalence of GERD symptoms appeared to increase until 1999. Risk factors for complications of GERD include advanced age, male sex, white race, abdominal obesity, and tobacco use. Most patients with GERD present with heartburn and effortless regurgitation. Coexistent dysphagia is considered an alarm symptom, prompting evaluation. There is substantial overlap between symptoms of GERD and those of eosinophilic esophagitis, functional dyspepsia, and gastroparesis, posing a challenge for patient management.

Abstract
Objectives: We aimed to evaluate the effect of medical and diet therapies on esophageal distensibility assessed using the functional lumen imaging probe (FLIP) and the association of changes in esophageal distensibility with clinical outcomes in eosinophilic esophagitis (EoE). Methods: Patients with EoE were evaluated with FLIP during endoscopy at baseline and following therapy without interval dilatation. Evaluation also included a validated patient-reported outcome (PRO; a positive PRO was considered at a 30% score improvement), mucosal biopsies, and scoring of endoscopic features of EoE. FLIP data were analyzed to calculate the distensibility plateau (DP). Results: In all, 18 patients (ages 19–54 years; 4 female) treated with topical steroid (8), elimination diet (6), and/or proton-pump inhibitor (4 only treated with proton-pump inhibitor) were included. Follow-up testing occurred at a mean (range) of 14.6 (8–28) weeks. Improvement was observed in DP (13.9 (12.2–19.2) to 16.8 mm (15.8–19.2), P=0.007) and peak eosinophil count (45 (29–65) to 23 per high-power field (h.p.f.) (5–53), P=0.042). Nine patients had a positive symptomatic outcome. Six of 8 (75%) patients with a DP increase ≥2 mm had a positive PRO (P=0.077), while 2 of 7 (29%) patients that achieved an eosinophil count <15/h.p.f. had a positive PRO (P=0.167). Conclusions: Improvement in esophageal body distensibility can be achieved with medical and diet therapies without dilation in EoE. Improved DP appeared to be better indicator of symptomatic improvement than eosinophil count, supporting FLIP as a valuable outcome measure in EoE.

Abstract
Since first characterized in 2 small case series in the early 1990s, eosinophilic esophagitis (EoE) has emerged as a commonly identified cause of esophageal symptoms in children and adults.1,2 Although several highly effectively dietary, pharmacologic, and endoscopic therapies have been reported, none is currently approved by either the US Food and Drug Administration (FDA) or European regulatory authorities. Evolving diagnostic criteria have challenged drug development, in particular the recognition of complex interactions with the most prevalent esophageal disorder, gastroesophageal reflux disease (GERD). Heterogeneity in the clinical presentations of affected children and adults has created difficulties with uniform inclusion criteria and the development of disease-specific, patient-reported outcome (PRO) instruments. Furthermore, controversies regarding the appropriate therapeutic endpoints of EoE have impeded the design of clinical trials. Despite these obstacles, collaborative efforts by investigators, industry, the FDA, and patient advocacy groups have resulted in substantial progress in drug development in EoE over the past 2 decades.3 The purpose of this article is to summarize discussions on EoE based on the 2016 Drug Development Conference sponsored by the Center for Diagnostics and Therapeutics of the American Gastroenterological Association.

Abstract
BACKGROUND Environmental factors associated with ethnicity may contribute to the occurrence of eosinophilic esophagitis. Our study aimed to investigate the influence of Helicobacter pylori on the ethnic variation of esophageal eosinophilia in a large national sample of patients undergoing esophago-gastro-duodenoscopy. METHODS The Miraca Life Sciences Database is an electronic repository of histopathologic patient records. A case-control study evaluated the influence of ethnicity on the occurrence of esophageal eosinophilia and how age, gender, and histologic diagnosis of H. pylori modify this relationship. RESULTS The total study population comprised 596 479 subjects, of whom 25 969 harbored a diagnosis of esophageal eosinophilia. Young age, male sex, and H. pylori infection in declining order exerted the strongest influence on the occurrence of esophageal eosinophilia. In comparison with the population comprising of Caucasians and African-Americans, esophageal eosinophilia was less common among patients of African (OR=0.10, 95% CI=0.01-0.46), Middle Eastern (0.22, 0.15-0.31), East Asian (0.32, 0.26-0.38), Indian (0.28, 0.21-0.37), Hispanic (0.40, 0.37-0.43), or Jewish descent (0.58, 0.51-0.66), but more common among patients of Northern European descent (1.25, 1.07-1.45). With the exception of Northern Europeans, all ethnic subgroups were characterized by a higher prevalence of H. pylori than the comparison group. A low prevalence of H. pylori was significantly associated with a high prevalence of esophageal eosinophilia (R2 =0.90, P<.001). CONCLUSION Esophageal eosinophilia prevalence markedly varies by patient ethnicity. As there is a strong inverse correlation between H. pylori and esophageal eosinophilia, H. pylori infection may be in part responsible for the observed ethnic distribution of esophageal eosinophilia.

Abstract
Non-IgE-mediated gastrointestinal food allergic disorders (non-IgE-GI-FA) including food protein-induced enterocolitis syndrome (FPIES), food protein-induced enteropathy (FPE), and food protein-induced allergic proctocolitis (FPIAP) are relatively uncommon in infants and young children, but are likely under-diagnosed. Non-IgE-GI-FA have a favorable prognosis, with majority resolving by age 3-5 years. Diagnosis relies on the recognition of symptoms pattern in FPIAP and FPIES and biopsy in FPE. Further studies are needed for a better understanding of the pathomechanism, which will lead eventually to the development of diagnostic tests and treatments. Limited evidence supports the role of food allergens in subsets of constipation, gastroesophageal reflux disease, irritable bowel syndrome, and colic. The immunologic pathomechanism is not fully understood and empiric prolonged avoidance of food allergens should be limited to minimize nutrient deficiency and feeding disorders/food aversions in infants.

Abstract
Eosinophilic esophagitis is a relatively recently discovered disease of increasing incidence and prevalence and is a common cause of dysphagia and food bolus impaction. The definition of eosinophilic esophagitis continues to evolve, most recently with the characterization of proton pump inhibitor-responsive esophageal eosinophilia. The number of high-quality prospective, controlled trials guiding therapeutic decisions in eosinophilic esophagitis has increased steadily over the past several years. Treatment options at present focus on dietary therapy, particularly implementation of a 6-food elimination diet, and medical therapy, primarily the use of swallowed, topical corticosteroids. Proton pump inhibitors play an important role in current management. Conservative esophageal dilation is effective at ameliorating dysphagia in symptomatic patients with esophageal strictures. We conducted an evidence-based review of the diagnosis and treatment options in adults with eosinophilic esophagitis. The understanding of eosinophilic esophagitis continues to be refined. Continued validation of appropriate endpoints, however, is essential to establish the efficacy of existing and novel therapeutic approaches.

Abstract
Eosinophilic esophagitis (EoE) is a chronic allergic inflammatory disease that is triggered by food and/or environmental allergens and is characterized by a clinical and pathologic phenotype of progressive esophageal dysfunction due to tissue inflammation and fibrosis. EoE is suspected in patients with painful swallowing, among other symptoms, and is diagnosed by the presence of 15 or more eosinophils per high-power field in one or more of at least four esophageal biopsy specimens. The prevalence of EoE is increasing and has now reached rates similar to those of other chronic gastrointestinal disorders such as Crohn's disease. In recent years, our understanding of the immunologic mechanisms underlying this condition has grown considerably. Thanks to new genetic, molecular, cellular, animal, and translational studies, we can now postulate a detailed pathway by which exposure to allergens results in a complex and coordinated type 2 inflammatory cascade that, if not intervened upon, can result in pain on swallowing, esophageal strictures, and food impaction. Here, we review the most recent research in this field to synthesize and summarize our current understanding of this complex and important disease.

Abstract
Collaborative efforts by pediatric and adult gastroenterologists, allergists, dieticians, and pathologists have brought about marked progress in the recognition, understanding, and management of eosinophilic esophagitis (EoE) over the past two decades. Once an esoteric diagnosis, EoE is now increasingly identified as a major cause of morbidity, afflicting both children and adults. The detection of mucosal eosinophils has evolved from a diagnostic feature of acid reflux to a biomarker of food sensitization of the esophagus. Translational studies and murine models have elucidated Th-2 immune pathways in EoE, inspiring the development of targeted biologic therapeutics. At the same time, validation of patient-reported outcomes and endoscopic end points has facilitated the implementation of clinical trials of novel therapeutics. Ongoing investigations have elucidated the importance of "looking beneath the surface" of the epithelium, focusing greater attention on the impact of esophageal remodeling in the clinical consequences of EoE. Elimination diets continue to gain popularity as an intriguing, highly effective, and non-pharmacologic therapy that lends credence to the concept that EoE is a food-driven, immunologic disorder.

Abstract
Eosinophilic esophagitis (EoE) is a chronic esophageal disease characterized by a Th2 inflammatory response triggered by food/environmental allergens. Solid data confirm that up to half of patients with suspected EoE achieve complete remission on proton pump inhibitors (PPI) therapy. This disease phenotype is currently labelled as PPI-responsive esophageal eosinophilia (PPI-REE). Albeit initially believed to represent gastro-esophageal reflux disease (GERD), evolving evidence has underscored that PPI-REE and EoE show a significant overlap regarding clinic, endoscopic, histologic, Th2 immune-mediated inflammation and gene expression features. Moreover, PPI therapy can effectively reverse Th2 inflammation and the EoE transcriptome expression in PPI-REE patients. Therefore, EoE and PPI-REE likely represent a common allergic disorder, where PPI therapy should be considered a short- and long-term therapeutic asset, along with diet and topical steroids.

Abstract
Consensus diagnostic recommendations to distinguish GORD from eosinophilic oesophagitis (EoE) by response to a trial of proton pump inhibitors (PPIs) unexpectedly uncovered an entity called 'PPI-responsive oesophageal eosinophilia' (PPI-REE). PPI-REE refers to patients with clinical and histological features of EoE that remit with PPI treatment. Recent and evolving evidence, mostly from adults, shows that patients with PPI-REE and patients with EoE at baseline are clinically, endoscopically and histologically indistinguishable and have a significant overlap in terms of features of Th2 immune-mediated inflammation and gene expression. Furthermore, PPI therapy restores oesophageal mucosal integrity, reduces Th2 inflammation and reverses the abnormal gene expression signature in patients with PPI-REE, similar to the effects of topical steroids in patients with EoE. Additionally, recent series have reported that patients with EoE responsive to diet/topical steroids may also achieve remission on PPI therapy. This mounting evidence supports the concept that PPI-REE represents a continuum of the same immunological mechanisms that underlie EoE. Accordingly, it seems counterintuitive to differentiate PPI-REE from EoE based on a differential response to PPI therapy when their phenotypic, molecular, mechanistic and therapeutic features cannot be reliably distinguished. For patients with symptoms and histological features of EoE, it is reasonable to consider PPI therapy not as a diagnostic test, but as a therapeutic agent. Due to its safety profile, ease of administration and high response rates (up to 50%), PPI can be considered a first-line treatment before diet and topical steroids. The reasons why some patients with EoE respond to PPI, while others do not, remain to be elucidated.

Abstract
Eosinophilic esophagitis (EoE) is a chronic immune disease, characterized by a dense eosinophilic infiltrate in the esophagus, leading to bolus impaction and reflux-like symptoms. Traditionally considered a pediatric disease, the number of adult patients with EoE is continuously increasing, with a relatively higher incidence in western countries. Dysphagia and food impaction represent the main symptoms complained by patients, but gastroesophageal reflux-like symptoms may also be present. Esophageal biopsies are mandatory for the diagnosis of EoE, though clinical manifestations and proton pump inhibitors responsiveness must be taken into consideration. The higher prevalence of EoE in patients suffering from atopic diseases suggests a common background with allergy, however both the etiology and pathophysiology are not completely understood. Elimination diets are considered the first-line therapy in children, but this approach appears less effective in adults patients, who often require steroids; despite medical treatments, EoE is complicated in some cases by esophageal stricture and stenosis, that require additional endoscopic treatments. This review summarizes the evidence on EoE pathophysiology and illustrates the safety and efficacy of the most recent medical and endoscopic treatments.

Abstract
BACKGROUND Eosinophilic oesophagitis is a chronic, immune/antigen-mediated oesophageal disease, only recently, but increasingly, recognised in the world literature. It is diagnosed and managed primarily by medical gastroenterologists and allergy specialists, and is a distinct disease entity, affecting both children and adults. Few studies have been published in otolaryngology journals, although otolaryngologists will encounter patients with undiagnosed eosinophilic oesophagitis. Patients may present with dysphagia, bolus obstruction or with other ENT disorders, such as atopic rhinitis, reflecting the underlying systemic allergic disorder. OBJECTIVE This paper systematically reviews the evidence base published on the epidemiology, clinical presentation, diagnosis, treatment and prognosis of eosinophilic oesophagitis, particularly as it relates to otolaryngology practice.
