Abstract
Background Massive eosinophil infiltration into the esophagus is associated with subepithelial fibrosis and esophageal stricture in patients with eosinophilic esophagitis (EoE). However, the pathogenesis of esophageal fibrosis remains unclear. Objective We sought to elucidate the cellular and molecular mechanisms underlying the induction of esophageal fibrosis. Methods We established a murine model of EoE accompanied by fibrotic responses following long-term intranasal administration of house dust mite antigen. Using this murine model, we investigated the characteristics of immune cells infiltrating the fibrotic region of the inflamed esophagus using flow cytometry and histological analyses. We also analyzed the local inflammatory sites in the esophagus of patients with EoE using single-cell RNA sequencing, flow cytometry, and immunohistochemistry. Results Enhanced infiltration of both amphiregulin-producing and IL-5-producing TH2 cells was detected in the fibrotic area of the esophagus in mice subjected to repeated house dust mite exposure. Deletion of amphiregulin in CD4+ T cells ameliorates esophageal fibrosis. An analysis of human esophageal biopsy samples showed that the infiltration of amphiregulin-producing CD4+ T cells was higher in patients with EoE than in control patients. Furthermore, the number of infiltrated amphiregulin-producing CD4+ T cells was associated with the degree of esophageal fibrosis in patients with EoE. Conclusions Amphiregulin, produced by TH2 cells, contributes to esophageal fibrosis in EoE and may be a therapeutic target.

Optimal Assessment, Treatment, and Monitoring of Adults with Eosinophilic Esophagitis: Strategies to Improve Outcomes. Immunotargets Ther 2024; 13:367-383.

Abstract
Eosinophilic esophagitis (EoE) is a chronic type 2 inflammation-mediated disease characterized by an eosinophil-predominant inflammation of the esophagus and symptoms of esophageal dysfunction. Relevant treatment outcomes in the setting of EoE include the improvement of histology, symptoms, and endoscopy findings, quality of life (QoL), and the psychological burden of the disease. Established validated tools for the assessment of EoE include questionnaires on dysphagia and QoL (ie, DSQ, EEsAI, and EoE-IQ). More recently, esophageal symptom-specific anxiety and hypervigilance, assessed using the esophageal hypervigilance and anxiety scale (EHAS), have emerged as contributors to disease burden, confirming the importance of psychological aspects in EoE patients. The EoE endoscopic reference score (EREFS) is the only validated endoscopy score in EoE and can quantify mucosal disease burden. However, esophageal panometry using the functional lumen imaging probe (FLIP) and high-resolution manometry (HRM) have shown potential to optimize the assessment of fibrostenotic features of EoE, providing novel insights into the pathophysiology of symptoms. There is a growing number of licenced and off-label therapeutic options in EoE, with various randomized controlled trials demonstrating the efficacy of proton pump inhibitors, topical steroids, food elimination diets, biological drugs, and esophageal dilatation. However, standardized optimal management strategies of EoE are currently lacking. In this review, we provide an overview of established and novel assessment tools in EoE including patient reported outcomes, FLIP panometry, HRM, endoscopy, and histology outcome measures to improve the outcomes of EoE patients. In addition, we summarize available therapeutic options for EoE based on the most recent evidence.

Abstract
The present document constitutes Part 2 of the EoETALY Consensus Statements guideline on the diagnosis and management of eosinophilic esophagitis (EoE) developed by experts in the field of EoE across Italy (i.e., EoETALY Consensus Group). Part 1 was published as a different document, and included three chapters discussing 1) definition, epidemiology, and pathogenesis; 2) clinical presentation and natural history and 3) diagnosis of EoE. The present work provides guidelines on the management of EoE in two final chapters: 4) treatment and 5) monitoring and follow-up, and also includes considerations on knowledge gaps and a proposed research agenda for the coming years. The guideline was developed through a Delphi process, with grading of the strength and quality of the evidence of the recommendations performed according to accepted GRADE criteria.This document has received the endorsement of three Italian national societies including the Italian Society of Gastroenterology (SIGE), the Italian Society of Neurogastroenterology and Motility (SINGEM), and the Italian Society of Allergology, Asthma, and Clinical Immunology (SIAAIC). The guidelines also involved the contribution of members of ESEO Italia, the Italian Association of Families Against EoE.

Abstract
INTRODUCTION There are limited data characterizing eating habits among pediatric patients with eosinophilic esophagitis (EoE). We compared eating behaviors in pediatric patients with EoE with healthy controls and assessed the degree of correlation with symptomatology, endoscopic and histologic findings, and esophageal distensibility. METHODS We conducted a prospective, observational study where subjects consumed 4 food textures (puree, soft solid, chewable, and hard solid) and were scored for eating behaviors including number of chews per bite, sips of fluid per food, and consumption time. Symptomatic, endoscopic, histologic, and esophageal distensibility data were collected for case subjects. RESULTS Twenty-seven case subjects and 25 healthy controls were enrolled in our study (mean age 11.0 years, 63.5% male). Compared with healthy controls, pediatric patients with EoE demonstrated more chews per bite with soft solid (13.6 vs 9.1, P = 0.031), chewable (14.7 vs 10.7, P = 0.047), and hard solid foods (19.0 vs 12.8, P = 0.037). Patients with EoE also demonstrated increased consumption time with soft solid (94.7 vs 58.3 seconds, P = 0.002), chewable (90.0 vs 65.1 seconds, P = 0.005), and hard solid foods (114.1 vs 76.4 seconds, P = 0.034) when compared with healthy controls. Subgroup analysis based on disease status showed no statistically significant differences in eating behaviors between active and inactive EoE. Total endoscopic reference score positively correlated with consumption time ( r = 0.53, P = 0.008) and number of chews ( r = 0.45, P = 0.027) for chewable foods and with number of chews ( r = 0.44, P = 0.043) for hard solid foods. Increased consumption time correlated with increased eosinophil count ( r = 0.42, P = 0.050) and decreased esophageal distensibility ( r = -0.82, P < 0.0001). DISCUSSION Altered eating behaviors including increased chewing and increased consumption time can be seen in pediatric patients with EoE, can persist despite histologic remission, and may be driven by changes in esophageal distensibility.

Abstract
INTRODUCTION There are limited longitudinal data on the impact of chronic therapy on the natural history of eosinophilic esophagitis (EoE), a chronic allergic disease of the esophagus. The purpose of this study was to evaluate if patients with well-controlled EoE were less likely to develop fibrostenotic complications. METHODS Subjects were identified from a database of pediatric patients with EoE at the Children's Hospital of Philadelphia started in 2000. Patients were then searched in adult medical records to identify patients who transitioned care. All office visits, emergency department visits, and endoscopic, histologic, and imaging reports were reviewed for the primary outcome of strictures and the secondary outcomes of food impactions and dysphagia. Cox proportional hazard regression was performed for outcomes. RESULTS One hundred five patients were identified with the mean follow-up of 11.4 ± 4.9 years. 52.3% (n = 55) had a period of histologic disease control defined as ≥2 consecutive endoscopies with histologic remission. These patients were less likely to develop strictures compared with patients who did not have a period of histologic control (HR 0.232; 95% CI 0.084-0.64, P = 0.005). Patients who were diagnosed at younger ages were less likely to develop strictures. Presentation with dysphagia or impaction was associated with higher rate of stricture development. DISCUSSION In this cohort study with > 10 years of follow-up, children with EoE with a period of histologic disease control and diagnosed at younger ages were less likely to develop esophageal strictures. While this suggests histologic remission is associated with reduction of remodeling complications, additional prospective data with long-term follow-up are needed.

Abstract
BACKGROUND The mechanistic basis of the variable symptomatology seen in eosinophilic esophagitis (EoE) remains poorly understood. OBJECTIVE We examined the correlation of a validated, patient-reported outcome metric with a broad spectrum of esophageal transcripts to uncover potential symptom pathogenesis. METHODS We extracted data from 146 adults with EoE through the Consortium of Eosinophilic Gastrointestinal Disease Researchers. Patients were subgrouped by esophageal dilation history. We compared a validated patient-reported outcome metric, the EoE Activity Index (EEsAI), with a set of transcripts expressed in the esophagus of patients with EoE, the EoE Diagnostic Panel (EDP). We used single-cell RNA sequencing data to identify the cellular source of EEsAI-related EDP genes and further analyzed patients with mild and severe symptoms. RESULTS The EEsAI correlated with the EDP total score, especially in patients without recent esophageal dilation (r = -0.31; P = .003). We identified 14 EDP genes that correlated with EEsAI scores (r ≥ 0.3; P < .05). Of these, 11 were expressed in nonepithelial cells and three in epithelial cells. During histologic remission, only four of 11 nonepithelial genes (36%) versus all three epithelial genes (100%) had decreased expression to less than 50% of that in active EoE. Fibroblasts expressed five of 11 nonepithelial EEsAI-associated EDP genes (45%). A subset of nonepithelial genes (eight of 11; 73%), but not EoE-representative genes (none of four; 0%; CCL26, CAPN14, DSG1, and SPINK7), was upregulated in patients with EoE with the highest versus lowest symptom burden. CONCLUSION The correlation of symptoms and nonepithelial esophageal gene expression substantiates that nonepithelial cells (eg, fibroblasts) likely contribute to symptom severity.

Clinical and molecular correlates of the Index of Severity for Eosinophilic Esophagitis. J Allergy Clin Immunol 2024:S0091-6749(24)00465-2.

Abstract
BACKGROUND The Index of Severity for Eosinophilic Esophagitis (I-SEE) is a new expert-defined clinical tool that classifies disease severity of eosinophilic esophagitis (EoE). OBJECTIVE We aimed to determine whether I-SEE is associated with patient characteristics, molecular features of EoE, or both. METHODS We analyzed a prospective cohort of patients with EoE from the Consortium of Eosinophilic Gastrointestinal Disease Researchers (CEGIR). Associations between I-SEE and clinical and molecular features (assessed by an EoE diagnostic panel [EDP]) were assessed. RESULTS In 318 patients with chronic EoE (209 adults, 109 children), median total I-SEE score was 7.0, with a higher symptoms and complications score in children than adults (4.0 vs 1.0; P < .001) and higher inflammatory and fibrostenotic features scores in adults than children (3.0 vs 1.0 and 3.0 vs 0, respectively; both P < .001). Total I-SEE score had a bimodal distribution with the inactive to moderate categories and severe category. EDP score correlated with total I-SEE score (r = -0.352, P < .001) and both inflammatory and fibrostenotic features scores (r = -0.665, P < .001; r = -0.446, P < .001, respectively), but not with symptoms and complications scores (r = 0.047, P = .408). Molecular severity increased from inactive to mild and moderate, but not severe, categories. Longitudinal changes of modified I-SEE scores and inflammatory and fibrostenotic features scores reflected histologic and molecular activity. CONCLUSIONS I-SEE score is associated with select clinical features across severity categories and with EoE molecular features for nonsevere categories, warranting further validation.

Abstract
Microscopic examination of esophageal biopsies is essential to diagnose eosinophilic esophagitis (EoE). Eosinophil inflammation is the basis for the diagnosis, but additional abnormalities may contribute to persistent symptoms and epithelial barrier dysfunction. Both peak eosinophil count and assessments of additional features should be included in pre-therapy and post-therapy pathology reports. Pathologic abnormalities identified in esophageal biopsies of EoE are reversible in contrast to esophageal strictures.

Abstract
Measuring health-related quality of life (HRQOL) gained relevance in research and clinical practice in patients with eosinophilic esophagitis. The physical discomfort and social and psychological consequences of this food-related disease substantially affect HRQOL. Determinant of an impaired HRQOL include symptom severity, disease duration, biological disease activity, and psychological factors. Patients prioritize symptom relief and improved HRQOL as treatment objectives. Available treatment options can address these goals; however, there is a suboptimal adherence to treatment. There is a need for enhanced patient guidance and education. The assessment of HRQOL will help to prioritize patient's needs in management.

Abstract
Most of the major clinical signs and consequences of eosinophilic esophagitis seem to be related to tissue remodeling. Important data on remodeling activity in patients with eosinophilic esophagitis are provided by a range of current and new biologic markers and diagnostics. To completely clarify the possible advantages and restrictions of therapeutic approaches, clinical studies should take into consideration the existence and reversibility of esophageal remodeling. The degree of mucosal or submucosal disease activity may not be reflected by epithelial eosinophilic inflammation, which is used to define one criterion of disease activity".

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
Unsedated transnasal endoscopy (TNE) is an alternative method of examining the esophageal mucosa in pediatric patients with eosinophilic esophagitis (EoE), reducing cost, time, and risk associated with frequent surveillance esophagogastroduodenoscopies (EGD). Adequacy of transnasal esophageal biopsies for the evaluation of eosinophilic esophagitis histologic scoring system (EoEHSS) has not yet been evaluated. We compared procedure times, endoscopic findings, and EoEHSS scoring for EoE patients undergoing TNE versus standard EGD. Sixty-six TNE patients and 132 EGD controls matched for age (mean age 14.0 years) and disease status (29.3% active) were included. Compared to patients undergoing standard EGD, patients undergoing TNE spent 1.94 h less in the GI suite (p < 0.0001), with comparable occurrence rates of all visual endoscopic findings and most EoEHSS components. TNE serves as a useful tool for long-term disease surveillance, and consideration should be given to its use in clinical trials for EoE.

Abstract
BACKGROUND & AIMS Dupilumab is approved for treatment of eosinophilic esophagitis (EoE), but real-world data are lacking. We aimed to determine the real-world efficacy of dupilumab in patients with severe, treatment-refractory, and fibrostenotic EoE. METHODS We conducted a retrospective cohort study of EoE patients prescribed dupilumab and who were treatment-refractory to standard modalities. Patient demographics, clinical characteristics, EoE history, and procedural data (including the histologically worst, predupilumab, and postdupilumab endoscopies) were extracted from medical records. Symptomatic, endoscopic, and histologic responses were assessed for the worst and predupilumab endoscopies compared with the postdupilumab endoscopy. RESULTS We identified 46 patients with refractory fibrostenotic EoE who were treated with dupilumab. Patients showed endoscopic, histologic, and symptomatic improvement on dupilumab compared with both the worst and the predupilumab esophagogastroduodenoscopies. The peak eosinophil counts decreased markedly, and postdupilumab histologic response rates were 80% and 57% for fewer than 15 eosinophils per high-power field and 6 or fewer eosinophils per high-power field, respectively, and the Endoscopic Reference Score decreased from 5.01 to 1.89 (P < .001 for all). Although the proportion of strictures was stable, there was a significant increase in the predilation esophageal diameter (from 13.9 to 16.0 mm; P < .001). Global symptom improvement was reported in 91% (P < .001). CONCLUSIONS In this population of severe, refractory, and fibrostenotic EoE patients, most achieved histologic, endoscopic, and symptom improvement with a median of 6 months of dupilumab, and esophageal stricture diameter improved. Dupilumab has real-world efficacy for a severe EoE population, most of whom would not have qualified for prior clinical trials.

Abstract
OBJECTIVES The objective of this study was to evaluate the efficacy and safety of budesonide oral suspension (BOS) in adolescents with eosinophilic esophagitis (EoE). METHODS This post hoc analysis pooled data from two 12-week, randomized, double-blind, placebo-controlled studies of BOS 2.0 mg twice daily (b.i.d.) (phase 2, NCT01642212; phase 3, NCT02605837) in patients aged 11-17 years with EoE and dysphagia. Efficacy endpoints included histologic (≤6, ≤1, and <15 eosinophils per high-power field [eos/hpf]), dysphagia symptom (≥30% reduction in Dysphagia Symptom Questionnaire [DSQ] scores from baseline), and clinicopathologic (≤6 eos/hpf and ≥30% reduction in DSQ scores from baseline) responses at week 12. Change from baseline to week 12 in peak eosinophil counts, DSQ scores, EoE Histology Scoring System (EoEHSS) grade (severity) and stage (extent) total score ratios (TSRs), and total EoE Endoscopic Reference Scores (EREFS) were assessed. Safety outcomes were also examined. RESULTS Overall, 76 adolescents were included (BOS, n = 45; placebo, n = 31). Significantly more patients who received BOS than placebo achieved histologic responses (≤6 eos/hpf: 46.7% vs 6.5%; ≤1 eos/hpf: 42.2% vs 0.0%; <15 eos/hpf: 53.3% vs 9.7%; P < 0.001) and a clinicopathologic response (31.1% vs 3.2%; P = 0.003) at week 12. More BOS-treated than placebo-treated patients achieved a dysphagia symptom response at week 12 (68.9% vs 58.1%; not statistically significant P = 0.314). BOS-treated patients had significantly greater reductions in EoEHSS grade and stage TSRs ( P < 0.001) and total EREFS ( P = 0.021) from baseline to week 12 than placebo-treated patients. BOS was well tolerated, with no clinically meaningful differences in adverse events versus placebo. CONCLUSIONS BOS 2.0 mg b.i.d. significantly improved most efficacy outcomes in adolescents with EoE versus placebo.

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
Eosinophilic esophagitis (EoE) is a chronic immune-mediated food antigen-driven disease characterized by tissue eosinophilia and clinical symptoms of esophageal dysfunction. Medical and dietary therapies can be offered as treatment options in both pediatric and adult populations. Advances in nutritional research in EoE have produced different levels of dietary restriction, ranging from elimination of a single food group to more extensive restriction such as the two-food elimination diet, four-food elimination diet, or six-food elimination diet. Efficacy and outcomes vary for each level of restriction. The option of using dietary therapy allows clinicians to partner with patients in shared decision-making to balance the right level of food antigen restriction for the desired outcome. Key considerations when choosing dietary therapy hinge on patient preference and resources, food-related quality of life, and the ability to provide nutritional diversity and maintain nutritional parameters. This article highlights these considerations and offers clinical pearls to guide clinicians who wish to incorporate dietary therapy of EoE into their practice.

Abstract
OBJECTIVE We aimed to determine whether mepolizumab, an anti-IL-5 antibody, was more effective than placebo for improving dysphagia symptoms and decreasing oesophageal eosinophil counts in eosinophilic oesophagitis (EoE). METHODS We conducted a multicentre, randomised, double-blind, placebo-controlled, trial. In the first part, patients aged 16-75 with EoE and dysphagia symptoms (per EoE Symptom Activity Index (EEsAI)) were randomised 1:1 to 3 months of mepolizumab 300 mg monthly or placebo. Primary outcome was change in EEsAI from baseline to month 3 (M3). Secondary outcomes included histological, endoscopic and safety metrics. In part 2, patients initially randomised to mepolizumab continued 300 mg monthly for 3 additional months (mepo/mepo), placebo patients started mepolizumab 100 mg monthly (pbo/mepo), and outcomes were reassessed at month 6 (M6). RESULTS Of 66 patients randomised, 64 completed M3, and 56 completed M6. At M3, EEsAI decreased 15.4±18.1 with mepolizumab and 8.3±18.0 with placebo (p=0.14). Peak eosinophil counts decreased more with mepolizumab (113±77 to 36±43) than placebo (146±94 to 160±133) (p<0.001). With mepolizumab, 42% and 34% achieved histological responses of <15 and ≤6 eos/hpf compared with 3% and 3% with placebo (p<0.001 and 0.02). The change in EoE Endoscopic Reference Score at M3 was also larger with mepolizumab. At M6, EEsAI decreased 18.3±18.1 points for mepo/mepo and 18.6±19.2 for pbo/mepo (p=0.85). The most common adverse events were injection-site reactions. CONCLUSIONS Mepolizumab did not achieve the primary endpoint of improving dysphagia symptoms compared with placebo. While eosinophil counts and endoscopic severity improved with mepolizumab at 3 months, longer treatment did not yield additional improvement. TRIAL REGISTRATION NUMBER NCT03656380.

Prospective study of an amino acid-based elemental diet in an eosinophilic gastritis and gastroenteritis nutrition trial. J Allergy Clin Immunol 2023; 152:676-688. [PMID: 37462600 PMCID: PMC10528593 DOI: 10.1016/j.jaci.2023.05.024] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 04/21/2023] [Accepted: 05/11/2023] [Indexed: 09/09/2023]
Abstract
BACKGROUND Eosinophilic gastritis/gastroenteritis (EoG/EoGE) are rare disorders with pathologic gastric and/or small intestinal eosinophilia lacking an approved therapy. An allergic mechanism is postulated but underexplored mechanistically and therapeutically. OBJECTIVE We evaluated the effectiveness of a food allergen-free diet (elemental formula) in controlling gastrointestinal eosinophilia in adult EoG/EoGE. METHODS Adults aged 18 to 65 years with histologically active EoG/EoGE (≥30 eosinophils per high-power field) in the stomach and/or duodenum and gastrointestinal symptoms within the month preceding enrollment were prospectively enrolled onto a single-arm clinical trial to receive elemental formula for 6 consecutive weeks. The primary end point was percentage of participants with complete histologic remission (<30 eosinophils per high-power field in both stomach and duodenum). Exploratory outcomes were improvement in symptoms, endoscopy results, blood eosinophilia, quality of life, Physician Global Assessment score, and EoG-relevant gastric transcriptome and microbiome. RESULTS Fifteen adults (47% male, average age 37.7 years, average symptom duration 8.8 years) completed the trial. Multi-gastrointestinal segment involvement affected 87%. All subjects had complete histologic remission in the stomach (P = .002) and duodenum (P = .001). Scores improved in overall PhGA (P = .002); EGREFS (P = .003); EGDP (P = .002); SODA pain intensity (P = .044), non-pain (P = .039), and satisfaction (P = .0024); and PROMIS depression (P = .0078) and fatigue (P = .04). Food reintroduction reversed these improvements. The intervention was well tolerated in 14 subjects, with 1 serious adverse event reported in 1 subject. CONCLUSION An amino acid-based elemental diet improves histologic, endoscopic, symptomatic, quality-of-life, and molecular parameters of EoG/EoGE; these findings and disease recurrence with food trigger reintroduction support a dominant role for food allergens in disease pathogenesis.

Food-Specific IgG4 Is Elevated Throughout the Upper Gastrointestinal Tract in Eosinophilic Esophagitis. Dig Dis Sci 2023; 68:2406-2413. [PMID: 36973521 PMCID: PMC10198037 DOI: 10.1007/s10620-023-07924-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Accepted: 03/12/2023] [Indexed: 03/29/2023]
Abstract
BACKGROUND Food-specific immunoglobulin G4 (FS-IgG4) is associated with eosinophilic esophagitis (EoE); however, it is not clear whether production is limited to the esophagus. AIMS To assess FS-IgG4 levels in the upper gastrointestinal tract and plasma and compare these with endoscopic disease severity, tissue eosinophil counts, and patient-reported symptoms. METHODS We examined prospectively banked plasma, throat swabs, and upper gastrointestinal biopsies (esophagus, gastric antrum, and duodenum) from control (n = 15), active EoE (n = 24), and inactive EoE (n = 8) subjects undergoing upper endoscopy. Patient-reported symptoms were assessed using the EoE symptom activity index (EEsAI). Endoscopic findings were evaluated using the EoE endoscopic reference score (EREFS). Peak eosinophils per high-power field (eos/hpf) were assessed from esophageal biopsies. Biopsy homogenates and throat swabs were normalized for protein content and assessed for FS-IgG4 to milk, wheat, and egg. RESULTS Median FS-IgG4 for milk and wheat was significantly increased in the plasma, throat swabs, esophagus, stomach, and duodenum of active EoE subjects compared to controls. No significant differences for milk- or wheat-IgG4 were observed between active and inactive EoE subjects. Among the gastrointestinal sites sampled, FS-IgG4 levels were highest in the esophagus. Esophageal FS-IgG4 for all foods correlated significantly across all sites sampled (r ≥ 0.59, p < 0.05). Among subjects with EoE, esophageal FS-IgG4 correlated significantly with peak eos/hpf (milk and wheat) and total EREFS (milk). EEsAI scores and esophageal FS-IgG4 levels did not correlate. CONCLUSIONS Milk and wheat FS-IgG4 levels are elevated in plasma and throughout the upper gastrointestinal tract in EoE subjects and correlate with endoscopic findings and esophageal eosinophilia.

Abstract
BACKGROUND Dupilumab, a fully human monoclonal antibody, blocks interleukin-4 and interleukin-13 signaling, which have key roles in eosinophilic esophagitis. METHODS We conducted a three-part, phase 3 trial in which patients 12 years of age or older underwent randomization in a 1:1 ratio to receive subcutaneous dupilumab at a weekly dose of 300 mg or placebo (Part A) or in a 1:1:1 ratio to receive 300 mg of dupilumab either weekly or every 2 weeks or weekly placebo (Part B) up to week 24. Eligible patients who completed Part A or Part B continued the trial in Part C, in which those who completed Part A received dupilumab at a weekly dose of 300 mg up to week 52 (the Part A-C group); Part C that included the eligible patients from Part B is ongoing. The two primary end points at week 24 were histologic remission (≤6 eosinophils per high-power field) and the change from baseline in the Dysphagia Symptom Questionnaire (DSQ) score (range, 0 to 84, with higher values indicating more frequent or more severe dysphagia). RESULTS In Part A, histologic remission occurred in 25 of 42 patients (60%) who received weekly dupilumab and in 2 of 39 patients (5%) who received placebo (difference, 55 percentage points; 95% confidence interval [CI], 40 to 71; P<0.001). In Part B, histologic remission occurred in 47 of 80 patients (59%) with weekly dupilumab, in 49 of 81 patients (60%) with dupilumab every 2 weeks, and in 5 of 79 patients (6%) with placebo (difference between weekly dupilumab and placebo, 54 percentage points; 95% CI, 41 to 66 [P<0.001]; difference between dupilumab every 2 weeks and placebo, 56 percentage points; 95% CI, 43 to 69 [not significant per hierarchical testing]). The mean (±SD) DSQ scores at baseline were 33.6±12.41 in Part A and 36.7±11.22 in Part B; the scores improved with weekly dupilumab as compared with placebo, with differences of -12.32 (95% CI, -19.11 to -5.54) in Part A and -9.92 (95% CI, -14.81 to -5.02) in Part B (both P<0.001) but not with dupilumab every 2 weeks (difference in Part B, -0.51; 95% CI, -5.42 to 4.41). Serious adverse events occurred in 9 patients during the Part A or B treatment period (in 7 who received weekly dupilumab, 1 who received dupilumab every 2 weeks, and 1 who received placebo) and in 1 patient in the Part A-C group during the Part C treatment period who received placebo in Part A and weekly dupilumab in Part C. CONCLUSIONS Among patients with eosinophilic esophagitis, subcutaneous dupilumab administered weekly improved histologic outcomes and alleviated symptoms of the disease.

Abstract
PURPOSE OF REVIEW This review will present what is known from recent research on the involvement of mast cells in eosinophilic esophagitis and identify questions requiring further investigation. RECENT FINDINGS In the adults and children with eosinophilic esophagitis, there is increasing evidence that mastocytosis can persist, despite resolution of eosinophilia and is associated with persistent mucosal abnormalities and symptoms. Despite, treatment mast cells have an activated transcriptome. Mast cells likely contribute to epithelial barrier dysfunction, smooth muscle hypertrophy and contraction, and subepithelial fibrosis. It remains unclear whether targeting MCs alone has therapeutic efficacy to improve tissue damage. SUMMARY Mast cells appear to play a key role in eosinophilic esophagitis and serve as a biomarker of mucosal healing in conjunction with eosinophils. Excessive mast cell activation likely contributes to tissue damage in eosinophilic esophagitis and need to be considered as a target of therapy along with eosinophils.

Disease Burden and Unmet Need in Eosinophilic Esophagitis. Am J Gastroenterol 2022; 117:1231-1241. [PMID: 35417421 DOI: 10.14309/ajg.0000000000001777] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Accepted: 04/04/2022] [Indexed: 12/11/2022]
Abstract
Eosinophilic esophagitis (EoE) is a chronic, progressive, type 2 inflammatory disease of increasing prevalence, characterized by symptoms of dysphagia and reduced quality of life. A dysregulated type 2 immune response to food and aeroallergen leads to barrier dysfunction, chronic esophageal inflammation, remodeling, and fibrosis. Patients with EoE have impaired quality of life because of dysphagia and other symptoms. They may also suffer social and psychological implications of food-related illness and expensive out-of-pocket costs associated with treatment. Disease burden in EoE is often compounded by the presence of comorbid type 2 inflammatory diseases. Current conventional treatments include elimination diet, proton pump inhibitors, and swallowed topical corticosteroids, as well as esophageal dilation in patients who have developed strictures. These treatments demonstrate variable response rates and may not always provide long-term disease control. There is an unmet need for long-term histologic, endoscopic, and symptomatic disease control; for targeted therapies that can normalize the immune response to triggers, reduce chronic inflammation, and limit or prevent remodeling and fibrosis; and for earlier diagnosis, defined treatment outcomes, and a greater understanding of patient perspectives on treatment. In addition, healthcare professionals need a better understanding of the patient perspective on disease burden, the disconnect between symptoms and disease activity, and the progressive nature of EoE and the need for continuous monitoring and maintenance treatment. In this review, we explore the progression of disease over the patient's lifespan, highlight the patient perspective on disease, and discuss the unmet need for effective long-term treatments.

A Clinical Severity Index for Eosinophilic Esophagitis: Development, Consensus, and Future Directions. Gastroenterology 2022; 163:59-76. [PMID: 35606197 PMCID: PMC9233087 DOI: 10.1053/j.gastro.2022.03.025] [Citation(s) in RCA: 36] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 03/11/2022] [Accepted: 03/13/2022] [Indexed: 12/26/2022]
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
Eosinophilic esophagitis is an immune-mediated allergic disease of the esophagus that affects pediatric patients of all ages. The diagnosis is made by esophagogastroduodenoscopy demonstrating eosinophilic infiltrate of the esophagus. Approaches to treatment involve proton pump inhibitors (PPIs), swallowed topical steroid preparations, as well as dietary elimination. In this review we discuss the evidence and efficacy of each of these approaches.
