Abstract
Eosinophilic esophagitis (EoE) and inflammatory bowel disease (IBD) are chronic inflammatory disorders of the gastrointestinal tract, with EoE predominantly provoked by food and aeroallergens, whereas IBD is driven by a broader spectrum of immunopathological and environmental triggers. This review presents a comprehensive comparison of the pathophysiological and therapeutic strategies for EoE and IBD. We examine the current understanding of their underlying mechanisms, particularly the interplay between environmental factors and genetic susceptibility. A crucial element in both diseases is the integrity of the epithelial barrier, whose disruption plays a central role in their pathogenesis. The involvement of eosinophils, mast cells, B cells, T cells, dendritic cells, macrophages, and their associated cytokines is examined, highlighting the importance of targeting cytokine signaling pathways to modulate immune-epithelial interactions. We propose that advances in computation tools will uncover the significance of G-protein coupled receptors (GPCRs) in connecting immune and epithelial cells, leading to novel therapies for EoE and IBD.

Proton pump inhibitor effect on esophageal protein signature of eosinophilic esophagitis, prediction, and evaluation of treatment response. Allergy 2024. [PMID: 39092539 DOI: 10.1111/all.16261] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 07/04/2024] [Accepted: 07/21/2024] [Indexed: 08/04/2024]
Abstract
BACKGROUND Recently, we have identified a dysregulated protein signature in the esophageal epithelium of eosinophilic esophagitis (EoE) patients including proteins associated with inflammation and epithelial barrier function; however, the effect of proton pump inhibitor (PPI) treatment on this signature is unknown. Herein, we used a proteomic approach to investigate: (1) whether PPI treatment alters the esophageal epithelium protein profile observed in EoE patients and (2) whether the protein signature at baseline predicts PPI response. METHODS We evaluated the protein signature of esophageal biopsies using a cohort of adult EoE (n = 25) patients and healthy controls (C) (n = 10). In EoE patients, esophageal biopsies were taken before (pre) and after (post) an 8-week PPI treatment, determining the histologic response. Eosinophil count PostPPI was used to classify the patients: ≥15 eosinophils/hpf as non-responders (non-responder) and < 15 eosinophils/hpf as responders (R). Protein signature was determined and differentially accumulated proteins were characterized to identify altered biological processes and signaling pathways. RESULTS Comparative analysis of differentially accumulated proteins between groups revealed common signatures between three groups of patients with inflammation (responder-PrePPI, non-responder-PrePPI, and non-responder-PostPPI) and without inflammation (controls and responder-PostPPI). PPI therapy almost reversed the EoE specific esophageal protein signature, which is enriched in pathways associated with inflammation and epithelial barrier function, in responder-PostPPI. Furthermore, we identified a set of candidate proteins to differentiate responder-PrePPI and non-responder-PrePPI EoE patients before treatment. CONCLUSION These findings provide evidence that PPI therapy reverses the alterations in esophageal inflammatory and epithelial proteins characterizing EoE, thereby providing new insights into the mechanism of PPI clinical response. Interestingly, our results also suggest that PPI response could be predicted at baseline in EoE.

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
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
Objectives To investigate differences in symptoms, allergy comorbidities, and eosinophilic inflammation at the time of diagnosis for patients with eosinophilic esophagitis (EoE) based on gender, race, and age of onset. Methods A retrospective study was conducted at a multidisciplinary EoE clinic; the correlation between histological findings, previously identified symptoms, associated comorbidities, and demographics including gender, race, as well as age of onset was examined. Chi-squared and Student's T-tests were utilized for statistical analysis. Results A total of 91 patients were enrolled in this study, with 70% being male and 67% identifying as White. Among the patients, 45% had an early onset of EoE (defined as ≤6 years old). We revealed that White patients and females were significantly more likely to report dysphagia, while non-White patients experienced significantly more vomiting symptoms and had a higher prevalence of asthma as a comorbidity. Early-onset patients exhibited a significantly higher rate of vomiting and had elevated eosinophilic counts compared to patients with EoE onset at a regular age. We also revealed that abdominal pain is associated with a lower average proximal eosinophilic counts. Conclusions Our study revealed the significant impact of gender, race, and age of onset on the phenotype and comorbidities of EoE, suggesting these factors should be considered when caring for these patients.

Abstract
BACKGROUND Identifying children needing endoscopic evaluation for suspected eosinophilic esophagitis (EoE) is crucial for prompt diagnosis and management. AIMS We aimed to develop a clinical prediction tool to distinguish children with EoE from children without the disease before endoscopy. METHODS We conducted a retrospective case-control study of children undergoing upper endoscopy at a tertiary care center. Clinical characteristics before endoscopy were extracted from 380 EoE cases and 380 controls without EoE. We built a predictive model for case-control status and performed age-stratified analyses. RESULTS After multivariable analysis, history of adaptive eating behaviors, food allergy, food impaction, male sex, and regurgitation were independently associated with EoE, and abdominal pain and failure to thrive with control status (AUC 0.81). Food allergy and male sex were predictors of EoE across all ages. Regurgitation and adaptive eating behaviors were specific to EoE in early (0-5 years) (AUC 0.74) and middle childhood (6-11 years) (AUC 0.82), while dysphagia and food impaction were specific to EoE in the adolescence (12-17 years) (AUC 0.87). CONCLUSION We determined age-specific clinical features that predict EoE with good discrimination in a pediatric population before endoscopy. Validation of this model in an independent population can confirm the utility of this tool.

Abstract
BACKGROUND AND AIMS Monoclonal antibodies (MAbs) have clinical benefits for treating several atopic diseases. However, consensus on its use for eosinophilic esophagitis (EoE) is lacking. The present meta-analysis aimed to compare the efficacy and safety of MAbs versus placebo for treating EoE. METHODS We searched PubMed, Embase, and Cochrane Library for randomized controlled trials (RCTs). The primary outcomes were changes in peak esophageal eosinophils count/high power field (HPF) and mean esophageal eosinophils count/HPF. The secondary outcomes were changes in the EoE-Histology Scoring System (EoE-HSS), Endoscopic Reference Score (EREFS), dysphagia score, and adverse events (AEs). We compared binary outcomes using risk ratio (RR) and continuous outcomes using mean difference (MD) or standardized mean difference (SMD), with 95% confidence interval (CI). Considering the diversity of mechanistic properties of MAbs, a pre-specified subgroup analysis by MAb mechanism of action was performed for all outcomes, provided that at least two studies were in each subgroup. Heterogeneity was assessed using Cochran's Q test and I2 statistics. RESULTS 6 RCTs were included (533 patients). Compared to placebo, MAbs led to a significant reduction in peak esophageal eosinophils count/HPF (MD -0.78; CI 95% -0.87, -0.6801) and mean esophageal eosinophils count/HPF (SMD -0.79; CI 95% -1.5, -0.08). Moreover, MAbs significantly reduced EoE-HSS scores (grade score: SMD -9.31; 95% CI -13.95, -4.6701; stage score: SMD -10.18; 95% CI -15.06, -5.31), EREFS (SMD -5.95; CI 95% -9.19, -2.71) and dysphagia score (SMD -1.79; CI 95% -3.36, -0.23) without increasing AEs compared to placebo. Among those MAbs whose mechanism of action includes the blockage of the receptor for IL-13 (Dupilumab, QAX576, and RPC4046), the scores of EoE-HSS grade, EoE-HSS stage, EREFS, and dysphagia were significantly reduced, and they presented a similar risk of overall and serious AEs compared to placebo. CONCLUSION MAbs seem effective and safe in reducing esophageal eosinophil infiltrate, EoE-HSS score, EREFS score, and dysphagia symptoms in patients with EoE. However, further evidence is needed to establish its place in EoE management.

Abstract
BACKGROUND Transnasal endoscopy (TNE) does not require general anesthesia, an attractive characteristic for monitoring eosinophilic esophagitis (EoE). We evaluated the adequacy of TNE-obtained esophageal biopsies using the EoE Histology Scoring System (EoEHSS). METHODS The Cincinnati Center for Eosinophilic Disorders database was searched for esophageal biopsies obtained by the same endoscopist, using either TNE or conventional endoscopy (CE). Whole-slide biopsy images were evaluated. The Mann-Whitney test was used for median (interquartile range) values and Fisher exact test for categorical variables. P ≤ .05 was considered significant. RESULTS Median age (P = .82) or height (P = .83) did not differ between TNE (n = 17) and CE (n = 17) groups. Although median largest piece size (mm2) differed between the groups (TNE: 0.59 (0.45, 0.86), CE: 2.24 (1.09, 2.82), P < .001), all 8 EoEHSS features were evaluated in each group; only 1 feature (lamina propria fibrosis) was missing in both groups (TNE: 19/34, CE: 11/34, P = .09). The median peak eosinophil count/high-power field differed (TNE: 3 (0, 29), CE: 16 (1, 66), P = .03), but overall grade (TNE: 0.17 (0.10, 0.29), CE: 0.22 (0.14, 0.46), P = .12), stage (TNE: 0.14 (0.10, 0.24), CE: 0.20 (0.10, 0.43), P = .15), and non-eosinophil-related individual EoEHSS scores did not differ. CONCLUSIONS TNE- and CE-obtained esophageal biopsies are similarly sufficient for evaluation of key pathological features in EoE.

J Pediatr Gastroenterol Nutr 2024; 78:1398-1402. [PMID: 38623937 DOI: 10.1002/jpn3.12222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 02/02/2024] [Accepted: 02/08/2024] [Indexed: 04/17/2024]
Abstract
OBJECTIVES Esophageal food impaction (EFI) is the sudden onset of dysphagia that occurs when a food bolus becomes lodged in the esophagus, requiring endoscopic removal. Scientific data on the prevalence and causes of EFI in children is lacking. The aim of this study was to provide further insights into EFI episodes in children. METHODS We have prospectively enrolled all children admitted for a first episode of EFI between March 2018 and March 2023. A fluoroscopic contrast study was performed in all patients to confirm the boluses and assess their position. Boluses were extracted by esophagogastroduodenoscopies, and esophageal biopsies were routinely obtained for histologic evaluation. RESULTS Over the study period, 41 children were admitted for a first episode of food impaction. Drooling was the most commonly reported symptom. Half children experiencing a first episode of food bolus were diagnosed with EoE (20/41, 48.8%). Almost a fourth of the episodes subtended a different condition, such as esophageal anastomotic, peptic or congenital strictures, stricturing caustic esophagitis, esophageal duplication, and achalasia. In the last fourth of patients the cause of EFI was not identified and thus probably related to quick eating and inadequate chewing of food. DISCUSSION Our study represents the largest known series of pediatric patients evaluated for food bolus impaction. Our main finding is the high frequency of EoE, which accounts for a half of EFI episodes in pediatric age, especially in older children. This finding highlights the importance of obtaining esophageal biopsies after the endoscopic bolus removal in children with EFI to provide a complete diagnostic evaluation.

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
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
Feeding is a complex skill requiring coordination of multiple body systems. Multiple factors are considered in feeding dysfunction in pediatric patients with eosinophilic gastrointestinal disorders, including overall development, nutritional status, mealtime behaviors, and medical comorbidities. Symptoms of feeding dysfunction vary by age, with maladaptive learned feeding behaviors spanning all age ranges. Knowledge of the normal acquisition of feeding skills is critical to interpret the impact of the disease and plan appropriate intervention. Assessment and treatment from a feeding and swallowing disorders specialist can dramatically impact successful outcomes in nutrition, growth, mealtime dynamics and ultimatly quality of life for children and their caregivers in home and social settings.

Abstract
Adult patients with eosinophilic esophagitis (EoE) typically present with a history of dysphagia for solids, sometimes with additional reflux-like pain and a history of prior food impactions. In contrast to these alarming symptoms, the general appearance and physical examination of adult patients with EoE is in line with apparently healthy individuals. Therefore, the diagnosis is based on a history of solid-food dysphagia and eosinophilic tissue infiltration. Importantly, the increasing prevalence of EoE variants, that is, typical EoE symptoms in the absence of a relevant eosinophilia, and several studies with eosinophil-targeting drugs, call the pathogenic role of eosinophils into question.

Abstract
Edema, rings, exudates, furrows, and strictures (EREFS) represent the major endoscopic features of eosinophilic esophagitis (EoE). The Endoscopic Reference System (EREFS) grading system is easy to learn and apply during daily clinical practice in the diagnosis and follow-up of EoE patients. When endoscopy is performed by an EoE-experienced physician, the EREFS criteria will identify the majority of EoE patients. The EREFS score from the area of greatest involvement of the esophagus should be reported. The EREFS grading system was formally validated as an endoscopy score and several randomized placebo-controlled trials have shown responsiveness of the EREFS score to therapeutic interventions.

Abstract
The diagnosis of eosinophilic esophagitis (EoE) is based on clinical symptoms of esophageal dysfunction and eosinophil predominant esophageal inflammation. Clinical symptoms in children with EoE vary based on age and may be nonspecific. EoE has a male predominance with the majority having comorbid atopic disorders. At present, treatment options include medications (proton pump inhibition, swallowed topical steroids), dietary therapy or biologic therapy (dupilumab, approved for those ≥12 years of age). Outside of EoE in the context of oral immunotherapy, EoE is typically chronic requiring lifelong therapy. Long-term complications including feeding difficulties, malnutrition, and fibrostenotic disease.

Abstract
Proton pump inhibitors (PPIs), swallowed topical corticosteroids (STSs), and dupilumab are highly effective therapies for the treatment of eosinophilic esophagitis. Shared decision-making informs the choice of therapy and factors such as ease of use, safety, cost, and efficacy should be addressed. PPIs are the most common medication utilized early in the disease course; however, for nonresponders, STSs are an excellent alternative. Dupilumab is unlikely to replace PPIs or STSs as first-line therapy, except in highly specific circumstances. Identification of novel biologic pathways and the development of small molecules may lead to a wider range of treatment options in the future.

Abstract
Eosinophilic Gastrointestinal Disorders (EGIDs) are a group of conditions characterized by abnormal eosinophil accumulation in the gastrointestinal tract. Among these EGIDs, Eosinophilic Esophagitis (EoE) is the most well documented, while less is known about Eosinophilic Gastritis (EoG), Eosinophilic Enteritis (EoN), and Eosinophilic Colitis (EoC). The role of endoscopy in EGIDs is pivotal, with applications in diagnosis, disease monitoring, and therapeutic intervention. In EoE, the endoscopic reference score (EREFS) has been shown to be accurate in raising diagnostic suspicion and effective in monitoring therapeutic responses. Additionally, endoscopic dilation is the first-line treatment for esophageal strictures. For EoG and EoN, while the literature is more limited, common endoscopic findings include erythema, nodules, and ulcerations. Histology remains the gold standard for diagnosing EGIDs, as it quantifies eosinophilic infiltration. In recent years, there have been significant advancements in the histological understanding of EoE, leading to the development of diagnostic scores and the identification of specific microscopic features associated with the disease. However, for EoG, EoN, and EoC, precise eosinophil count thresholds for diagnosis have not yet been established. This review aims to elucidate the role of endoscopy and histology in the diagnosis and management of the three main EGIDs and to analyze their strengths and limitations, their interconnection, and future research directions.

Abstract
Background: Eosinophilic esophagitis (EoE) is a disease that has been subcategorized into two endoscopic phenotypes: inflammatory and fibrostenotic. Moreover, studies have shown a link between EoE and immunoglobulin G4 (IgG4), a subclass of the immunoglobulin G (IgG) antibody. In this study, we aimed to evaluate the relationship between histologic IgG4 expression and endoscopic phenotypes in patients with EoE. Methods: This case-control study included patients diagnosed with EoE (n = 19) and patients with non-obstructive dysphagia without abnormal findings as controls (NOD; n = 12). The EoE group was further divided into three subgroups based on endoscopic phenotype: inflammatory, fibrostenotic, or combined. Retrospective examination of endoscopic findings and pathological slides was performed to analyze IgG4 staining. Results: Histological analysis revealed a significant difference in IgG4 cell count (15.00 vs. 0.58, p = 0.003) and eosinophil cell count (84.67 vs. 0.08, p < 0.001) between the EoE and NOD groups. Symptom manifestation and blood test results were similar across all three endoscopic EoE phenotypes. However, histological analysis revealed a significant difference in IgG4 cell count between the inflammatory, fibrostenotic, and combined phenotypes (4.13 vs. 17.6 vs. 59.7, p = 0.030). Conclusions: IgG4 expression was higher in EoE patients than in those with NOD, the highest being in the combined phenotype subgroup. These findings emphasize the important role of endoscopic and histological examination in diagnosing EoE and the need for further research in this area.

Abstract
Proton-pump inhibitors (PPIs) are the most administered first-line treatment for eosinophilic esophagitis (EoE). However, only around half of EoE patients respond histologically to a double dosage of PPI. In addition, 70% of responders maintain EoE in remission after tapering the PPI dose. In order to avoid endoscopy with biopsies-the only accurate method of assessing PPI response-efforts have been made to identify PPI responder patients. The clinical or endoscopic features and biomarkers evaluated so far, however, have not proven to be sufficient in predicting PPI response. Although new approaches based on omics technologies have uncovered promising biomarkers, the specialized and complex procedures required are difficult to implement in clinical settings. Alternatively, PPI pharmacogenetics based on identifying variations in CYP2C19 and STAT6 genes have shown promising results in EoE, and could easily be performed in most laboratories. Other genetic variations have also been associated with PPI response and may explain those cases not related to CYP2C19 or STAT6. Here, we provide an overview of PPI treatment in EoE and evidence of how genetic variations in CYP2C19 and other genes could affect PPI effectiveness, and also discuss studies evaluating the role of pharmacogenetics in predicting PPI response in patients with EoE.

Abstract
BACKGROUND Recurrent upper endoscopies are essential for monitoring therapy response and disease activity in patients with eosinophilic esophagitis (EoE), leading to increased costs, procedural complications, and anesthesia exposure. The aim of this study was to examine an office-based model using serial sedation-free blind esophageal epithelial brushing (BEEB) to monitor therapy response through eosinophil-derived neurotoxin (EDN) levels and guide therapy plans in pediatric EoE patients. METHODS EoE patients (≤21 years of age) were enrolled in this prospective study. Subjects were placed on dietary, pharmacologic, or combination therapy with the goal of inducing or maintaining remission. To assess response to sequential interventions, subjects underwent sequential sedation-free BEEBs through nasogastric tubes to measure EDN levels. Based on serial brushings, an individual plan of diet, medications, or a combination of both was created for each subject, and a final endoscopy was then performed to validate the accuracy of the individual plans. RESULTS Twenty-four subjects completed the study. The average peak eosinophil count in patients with active EoE was 58.1 ± 30.8 eosinophils per high-power field and mean EDN level was 165.2 ± 191.3 μg/mL. A total of 42 BEEBs were completed. Individual therapy plans based on sequential BEEB were accurate in 19 out of the 24 patients (79%) and specifically nine out of 10 patients (90%) treated with elimination diets. CONCLUSION This study suggests that office-based sedation-free BEEBs can be used to monitor therapy response and disease activity in pediatric EoE patients.

MEDICINES (BASEL, SWITZERLAND) 2024; 11:8.

Abstract
Eosinophilic esophagitis (EoE) disease activity can be caused by treatment non-adherence. Medication possession ratio (MPR) is an established metric of medication adherence. A higher MPR correlates with better outcomes in several chronic diseases, but MPR has not been investigated with respect to EoE. A retrospective cohort study was performed using an established EoE registry for the years 2005 to 2020. Treatment periods were identified, MPRs were calculated, and medical records were assessed for histologic remission (<15 eos/hpf), dysphagia, food impaction, stricture occurrence, and esophageal dilation that corresponded to each treatment period. In total, 275 treatment periods were included for analysis. The MPR in the histologic remission treatment period group was 0.91 (IQR 0.63-1) vs. 0.63 (IQR 0.31-0.95) for the non-remission treatment period group (p < 0.001). The optimal MPR cut-point for histologic remission was 0.7 (Sen 0.66, Spec 0.62, AUC 0.63). With MPRs ≥ 0.7, there were significantly increased odds of histologic remission (odds ratio 3.05, 95% confidence interval 1.79-5.30) and significantly decreased odds of dysphagia (OR 0.27, 95% CI 0.15-0.45), food impaction (OR 0.26, 95% CI 0.11-0.55), stricture occurrence (OR 0.52 95% CI 0.29-0.92), and esophageal dilation (OR 0.29, 95% CI 0.15-0.54). Assessing MPR before repeating an esophagogastroduodenoscopy may decrease unnecessary procedures in the clinical management of eosinophilic esophagitis.

Abstract
INTRODUCTION Given the lack of data, we aimed to explore which therapeutic endpoints pediatric patients with eosinophilic esophagitis (EoE) and their parents consider to be relevant. METHODS We created an educational brochure on EoE and a questionnaire, both of which were content-validated by pediatric patients and parents. Validated documents were sent to 112 patients and parents. They ranked the importance (5 levels) of short (during next 3 months) and long-term (≥1 year) treatment effect on symptoms, quality of life, endoscopic inflammation, stricture formation, histological inflammation, and fibrosis. RESULTS A total of 45 parents and 30 pediatric patients ≥11 years completed the questionnaires. Pediatric patients identified improvement in the following domains as most important in the short- and long-term, respectively: symptoms (73% vs. 77%), QoL (53% vs. 57%), histologic inflammation (47% vs. 50%), histologic fibrosis (40% vs. 33%), endoscopic inflammation (47% vs. 40%), and strictures (33% vs. 40%). Parents of children ≥11 years old classified improvement in the following domains as most important in the short- and long-term, respectively: symptoms (70% vs. 83%), QoL (63% vs. 80%), histologic inflammation (67% vs. 77%), histologic fibrosis (47% vs. 63%), endoscopic inflammation (77% vs. 80%), and strictures (40% vs. 53%). Agreement between caregiver and children on the short-term importance of treatment outcomes was as follows: symptoms (77%), QoL (40%), histologic inflammation and fibrosis (47% and 43%), endoscopic inflammation and strictures (50% and 40%). CONCLUSION Pediatric patients and parents attributed most importance to improvement in symptoms and QoL. Agreement between parents and patients regarding therapy goals is limited.

Abstract
PURPOSE OF REVIEW Food allergies are immune-mediated, complex disorders, which are the source of increasing health concern worldwide. The goal of this review is to present an updated summary of the food allergy (FA) burden among children and adults across different populations, focusing on research from the past 5 years. RECENT FINDINGS FAs impact a growing number of global residents-particularly those residing in higher-income, industrialized regions. Moreover, growing epidemiologic evidence suggests that the population health burden of non-IgE-mediated FAs, such as food protein-induced enterocolitis syndrome, may also be higher than previously reported. FA is a complex trait that impacts infants, children, as well as adults across the globe. The population health burden of both IgE- and non-IgE-mediated FAs is likely to grow in the absence of rapid advances and widespread implementation of effective FA prevention and treatment interventions. Systematic epidemiological research initiatives are needed, both nationally and globally, to better understand and reduce the burden of these allergic diseases.

Abstract
INTRODUCTION Differences in eosinophilic esophagitis (EoE) presentation and outcomes by ethnicity or race remain understudied. We aimed to determine whether EoE patients of Hispanic/Latinx ethnicity or non-White race have differences in presentation at diagnosis or response to topical corticosteroid (tCS) treatment. METHODS This retrospective cohort study included subjects of any age with a new diagnosis of EoE and documentation of ethnicity or race. For those who had treatment with tCS and follow-up endoscopy/biopsy, we assessed histologic response (<15 eosinophils/hpf), global symptom response, and endoscopic response. Hispanic EoE patients were compared with non-Hispanics at baseline and before and after treatment. The same analyses were repeated for White vs non-Whites. RESULTS Of 1,026 EoE patients with ethnicity data, just 23 (2%) were Hispanic. Most clinical features at presentation were similar to non-Hispanic EoE patients but histologic response to tCS was numerically lower (38% vs 57%). Non-White EoE patients (13%) were younger at diagnosis and had less insurance, lower zip code-level income, shorter symptom duration, more vomiting, less dysphagia and food impaction, fewer typical endoscopic features, and less dilation. Of 475 patients with race data treated with tCS, non-Whites had a significantly lower histologic response rate (41% vs 59%; P = 0.01), and odds of histologic response remained lower after controlling for potential confounders (adjusted odds ratio 0.40, 95% confidence intervals: 0.19-0.87). DISCUSSION Few EoE patients at our center were Hispanic, and they had similar clinical presentations as non-Hispanics. The non-White EoE group was larger, and presentation was less dysphagia-specific. Non-White patients were also less than half as likely to respond to tCS.

Review article: Emerging insights into the epidemiology, pathophysiology, diagnostic and therapeutic aspects of eosinophilic oesophagitis and other eosinophilic gastrointestinal diseases. Aliment Pharmacol Ther 2024; 59:322-340. [PMID: 38135920 PMCID: PMC10843587 DOI: 10.1111/apt.17845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 09/08/2023] [Accepted: 12/13/2023] [Indexed: 12/24/2023]
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
BACKGROUND The presentation of eosinophilic esophagitis (EoE) is heterogeneous, but trends over time are not known. AIM To determine whether clinical and endoscopic phenotypes at EoE diagnosis have changed over the past 2 decades. METHODS In this retrospective cohort study, adults and children with newly diagnosed EoE were phenotyped as follows: (1) inflammatory vs fibrostenotic vs mixed on endoscopy; (2) atopic vs non-atopic; (3) age at symptom onset; (4) age at diagnosis; (5) presence of autoimmune or connective tissue disease; and (6) responsive to steroids. The prevalence of different phenotypes was categorized by 5-year intervals. Multivariate analysis was performed to assess for changes in patient features over time. RESULTS Of 1187 EoE patients, age at diagnosis increased over time (from 22.0 years in 2002-2006 to 31.8 years in 2017-2021; p < 0.001) as did the frequency of dysphagia (67% to 92%; p < 0.001). Endoscopic phenotypes were increasingly mixed (26% vs 68%; p < 0.001) and an increasing proportion of patients had later onset of EoE. However, there were no significant trends for concomitant autoimmune/connective tissue disease or steroid responder phenotypes. On multivariate analysis, after accounting for age, dysphagia, and food impaction, the increase in the mixed endoscopic phenotype persisted (aOR 1.51 per each 5-year interval, 95% CI 1.31-1.73). CONCLUSION EoE phenotypes have changed over the past two decades, with increasing age at diagnosis and age at symptom onset. The mixed endoscopic phenotype also increased, even after controlling for age and symptomatology. Whether this reflects changes in provider recognition or disease pathophysiology is yet to be elucidated.

J Pediatr Gastroenterol Nutr 2024; 78:304-312. [PMID: 38374551 DOI: 10.1002/jpn3.12054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 09/24/2023] [Accepted: 09/26/2023] [Indexed: 02/21/2024]
Abstract
OBJECTIVES Eosinophil-derived neurotoxin (EDN) is a viable marker of eosinophilic esophagitis (EoE) disease activity. We studied the utility of measuring EDN from esophageal epithelial brushings for diagnosing EoE, focusing on two scenarios: (1) cases of exclusive distal eosinophilia and (2) cases of discrepancy between endoscopy and histology. METHODS Records of patients who underwent esophagogastroduodenoscopy (EGD) with EDN measured via esophageal brushings at Arnold Palmer Hospital for Children in Orlando, Florida from January 2014 to October 2018 were retrospectively reviewed. Demographics, clinical, endoscopic, and histologic data were collected. RESULTS We reviewed 231 patient records (66.7% male, mean age 10.3 years, range 1-22 years). EDN values correlated with endoscopic reference score (EREFS) and peak eosinophil count (PEC) (Spearman's rho = 0.756 (p < 0.001) and 0.824 (p < 0.001) respectively). Average PEC, EREFS, and EDN concentrations were higher in patients with active EoE than in controls or patients with EoE in remission (inactive). When grouping patients based on esophageal eosinophilia distribution, EDN mirrored PEC, and EREFS. Patients with exclusive distal eosinophilia had lower EDN concentrations than those with eosinophilia in >1 level of the esophagus (23.8 ± 46.1 mcg/mL vs. 171.3 ± 205.8 mcg/mL respectively, p < 0.001). EDN values were more consistent with EREFS in cases of discrepancies between endoscopic findings and pathology (p < 0.001). CONCLUSION EDN measured in esophageal brushing samples reflects disease activity objectively and accurately. It also offers significant value in cases of exclusive distal esophageal eosinophilia and when discrepancies exist between endoscopy and histology.

Abstract
BACKGROUND Esophageal strictures significantly impair patient quality of life and present a therapeutic challenge, particularly due to the high recurrence post-ESD/EMR. Current treatments manage symptoms rather than addressing the disease's etiology. This review concentrates on the mechanisms of esophageal stricture formation and recurrence, seeking to highlight areas for potential therapeutic intervention. METHODS A literature search was conducted through PUBMED using search terms: esophageal stricture, mucosal resection, submucosal dissection. Relevant articles were identified through manual review with reference lists reviewed for additional articles. RESULTS Preclinical studies and data from animal studies suggest that the mechanisms that may lead to esophageal stricture include overdifferentiation of fibroblasts, inflammatory response that is not healed in time, impaired epithelial barrier function, and multimethod factors leading to it. Dysfunction of the epithelial barrier may be the initiating mechanism for esophageal stricture. Achieving perfect in-epithelialization by tissue-engineered fabrication of cell patches has been shown to be effective in the treatment and prevention of esophageal strictures. CONCLUSION The development of esophageal stricture involves three stages: structural damage to the esophageal epithelial barrier (EEB), chronic inflammation, and severe fibrosis, in which dysfunction or damage to the EEB is the initiating mechanism leading to esophageal stricture. Re-epithelialization is essential for the treatment and prevention of esophageal stricture. This information will help clinicians or scientists to develop effective techniques to treat esophageal stricture in the future.

Abstract
BACKGROUND A low incidence of eosinophilic esophagitis (EoE) in children in the North Denmark Region (NDR) were measured in 2007-2017. Few of the children diagnosed before 2017 were treated to remission suggesting a lack of awareness. While there currently are no guidelines for treating EoE in Denmark, a new English guideline was published in 2022 renewing focus on the disease. OBJECTIVE The aim of this study was to measure the difference of current Danish clinical practice for treatment and follow-up of EoE children in the NDR with the new English guideline from the British Society of Gastroenterology (BSG) and the British Society of Pediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN). METHODS This retrospective, register-based DanEoE cohort study included 31 children diagnosed with EoE between 2007 and 2021 in NDR. Medical records were reviewed and information about treatment and follow-up were collected. RESULTS In 32% of the children with EoE in the NDR, first-line treatment corresponded with the new English guideline. One in 6 children were never started on any treatment even though treatment always is recommended. Histologic evaluation within 12 weeks as recommended was performed in 13% of the children. CONCLUSIONS In Denmark focus on improving EoE treatment and follow-up for children is needed, as there is a significant difference between current clinical practice and the recommendations in the new English guideline.

Abstract
BACKGROUND Prior work suggests eosinophilic oesophagitis (EoE) is rare in those aged over 65 years. However, elderly patients with EoE experience a substantial diagnostic delay from symptom onset to diagnosis. AIMS To assess if age predicted whether oesophageal biopsies were obtained in patients with EoE symptoms, what clinical features predict EoE in the elderly, and if EoE phenotype differs between elderly and non-elderly patients. METHODS We conducted a retrospective cohort study utilising the University of North Carolina (UNC) electronic medical record, EoE clinicopathologic database and UNC endoscopy software from July 2008 to April 2021. A sample of 193 elderly and non-elderly patients with dysphagia, chest pain and/or heartburn were assembled. Patients with EoE were newly diagnosed per contemporaneous guidelines. Patient demographics, clinical characteristics and procedural data were extracted. Summary statistics, bivariate and multivariate analyses were performed. RESULTS Of 193 patients, we included 91 elderly (47%) and 102 non-elderly (53%). Age independently predicted the odds of biopsies (adjusted odds ratio (aOR): 0.44 elderly vs. non-elderly; 95% CI: 0.21-0.92). Endoscopic features of EoE, but not symptoms, were more common in elderly than non-EoE elderly patients. Elderly patients with EoE differed from non-elderly only by time to diagnosis (aOR per year of symptoms preceding diagnosis: 1.08, 95% CI: 1.04-1.11). CONCLUSIONS Elderly patients with EoE have <50% the odds of oesophageal biopsies. There were no significant differences between elderly and non-elderly EoE patients, although endoscopic features helped discriminate the two groups. Our findings suggest that older age represents a barrier to EoE diagnosis.

Abstract
BACKGROUND AND AIMS Owing to 2018 expanded diagnostic criteria for eosinophilic esophagitis (EoE) and thus a possible increase in diagnosis, previous studies on the global incidence and prevalence of EoE may need to be updated. We aimed to describe global, regional, and national trends in the incidence and prevalence of EoE from 1976 to 2022 and analyze their associations with geographic, demographic, and social factors through a systematic review. METHODS We searched the PubMed/MEDLINE, Embase, CINAHL, Google Scholar, and Cochrane databases from their inception dates to December 20, 2022, for studies that reported the incidence or prevalence of EoE in the general population. We calculated the global incidence and prevalence of EoE using pooled estimates with 95% confidence intervals (CIs) and performed subgroup analysis based on age, sex, race, geographical area, World Bank income group, and diagnostic criteria of EoE. RESULTS Forty studies met the eligibility criteria, including over 288 million participants and 147,668 patients with EoE from 15 countries across the five continents. The global pooled incidence and prevalence of EoE were 5.31 cases per 100,000 inhabitant-years (95% CI, 3.98-6.63; number of studies, 27; sample population, 42,191,506) and 40.04 cases per 100,000 inhabitant-years (95% CI, 31.10-48.98; number of studies, 20; sample population, 30,467,177), respectively. The pooled incidence of EoE was higher in high-income countries (vs low- or middle-income countries), males, and North America (vs Europe and Asia). The global prevalence of EoE followed a similar pattern. The pooled prevalence of EoE gradually increased from 1976 to 2022 (1976-2001; 8.18; 95% CI, 3.67-12.69 vs 2017-2022; 74.42; 95% CI, 39.66-109.19 cases per 100,000 inhabitant-years). CONCLUSIONS The incidence and prevalence of EoE have increased substantially and vary widely across the world. Further research is needed to evaluate the incidence and prevalence of EoE in Asia, South America, and Africa.

Abstract
Our understanding of the influence of race and gender on the presentation of eosinophilic esophagitis (EoE) is incomplete. To address this gap, we examined the effect of race and gender on the presentation of EoE. In this retrospective study, we reviewed the medical records of 755 EoE patients and recorded their demographic, clinical, endoscopic, and histologic information. Descriptive statistics were used to characterize the cohort. Multivariate logistic regression was used to identify predictors of race and gender after accounting for potential confounders. There was a bimodal distribution for age at diagnosis of EoE. Approximately 43% had pediatric onset EoE, while 57% had adult onset EoE. Male (68%) predominance was observed. Dysphagia (57%) and abdominal pain (20%) were among the most common presenting symptoms. Multivariate analysis revealed that African Americans (AAs) were diagnosed earlier [aOR: 0.96 (95% CI: 0.95-0.99); P = 0.01] and had significantly lower odds of manifesting furrows [aOR: 0.30 (95% CI: 0.12-0.77); P = 0.01] as compared with Whites. Males were diagnosed earlier [aOR 0.98 (0.97-0.99; P = 0.04] and had higher odds of having abnormal endoscopic findings [aOR: 1.43 (1.05-1.97); P = 0.02] when compared with females. Race and gender influence the presentation of EoE. Future studies aimed at investigating the interplay between race, gender, and molecular mechanisms of EoE are warranted.

Abstract
Nitric oxide (NO) is a short-lived gas molecule which has been studied for its role as a signaling molecule in the vasculature and later, in a broader view, as a cellular messenger in many other biological processes such as immunity and inflammation, cell survival, apoptosis, and aging. Fractional exhaled nitric oxide (FeNO) is a convenient, easy-to-obtain, and non-invasive method for assessing active, mainly Th2-driven, airway inflammation, which is sensitive to treatment with standard anti-inflammatory therapy. Consequently, FeNO serves as a valued tool to aid the diagnosis and monitoring of several asthma phenotypes. More recently, FeNO has been evaluated in several other respiratory and/or immunological conditions, including allergic rhinitis, chronic rhinosinusitis with/without nasal polyps, atopic dermatitis, eosinophilic esophagitis, and food allergy. In this review, we aim to provide an extensive overview of the current state of knowledge about FeNO as a biomarker in type 2 inflammation, outlining past and recent data on the application of its measurement in patients affected by a broad variety of atopic/allergic disorders.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is a chronic progressive inflammatory disease of the esophagus, characterized by extracellular matrix remodeling and fibrotic stricture formation. Disease monitoring requires multiple re-endoscopies with esophageal biopsies. Hence non-invasive methods for determining tissue fibrosis and treatment efficacy are warranted. AIMS To investigate the ability of extracellular matrix proteins in serum as potential biomarkers of tissue remodeling and clinical, endoscopic, and histological disease outcomes in adult EoE patients. METHODS Protein-fingerprint assays were used to measure neo-epitope specific fragments of collagen remodeling, human-neutrophil elastase degraded calprotectin, and citrullinated or non-citrullinated vimentin in the serum of an adult EoE-cohort. Biomarker analysis, symptoms, endoscopic features and histological disease activity (eosinophils(eos) per high-power-field(hpf)) were evaluated at baseline and after six weeks of dietary intervention. RESULTS Patients with a baseline (Endoscopic Reference score) EREFS fibrosis subscore ≥ 2 presented with increased fibrolysis of cross-linked type III collagen (CTX-III) (p < 0.01), whereas low CTX-III levels were observed in patients achieving histological remission (< 15 eos/hpf) (vs. no histological remission (p < 0.05). Progression of endoscopic fibrosis after intervention was associated with increased levels of type-III (PRO-C3) and -VI collagen (PRO-C6) formation (all; p < 0.05). A baseline EREFS inflammatory subscore ≥ 2 correlated with higher neutrophilic activity (Cpa9-HNE) at week 6 (p < 0.05). Moreover, increased degradation of type-III (C3M) and -IV (C4M/PRO-C4) collagens were associated with remission of food impaction after intervention (all; p < 0.05). CONCLUSION Serum extracellular matrix remodeling proteins demonstrated potential as surrogate biomarkers for assessing histological disease remission, endoscopic fibrosis, and remission of symptoms of food impaction after diet intervention in adult EoE patients.

Abstract
Eosinophilic gastrointestinal diseases (EGIDs) are an emerging group of pathological entities characterized by an eosinophil-predominant infiltration of different tracts of the gut in the absence of secondary causes of eosinophilia. According to the specific tract of the gut involved, EGIDs can be classified into eosinophilic esophagitis (EoE), eosinophilic gastritis (EoG), eosinophilic enteritis (EoN), and eosinophilic colitis (EoC). The epidemiology of EGIDs is evolving rapidly. EoE, once considered a rare disease, now has an incidence and prevalence of 7.7 new cases per 100,000 inhabitants per years and 34.4 cases per 100,000 inhabitants per year, respectively. Fewer data are available regarding non-EoE EGIDs, whose prevalence are estimated to range between 2.1 and 17.6 in 100,000 individuals, depending on age, sex, and ethnicity. Diagnosis requires the presence of suggestive symptoms, endoscopic biopsies showing abnormal values of eosinophils infiltrating the gut, and exclusion of secondary causes of eosinophilia. EoE typically presents with dysphagia and episodes of food bolus impactions, while EoG, EoN, and EoC may all present with abdominal pain and diarrhea, with or without other non-specific symptoms. In addition, although different EGIDs are currently classified as different entities, there may be overlap between different diseases in the same patient. Despite EGIDs being relatively novel pathological entities, the research on possible treatments is rapidly growing. In this regard, several randomized controlled trials are currently ongoing to investigate novel molecules, including ad-hoc steroid formulations, immunosuppressants, and mostly monoclonal antibodies that target the specific molecular mediators of EGIDs. This narrative review provides an up-to-date overview of available and investigational drugs for different EGIDs.

Abstract
We describe a cohort of 33 patients with eosinophilic esophagitis (EoE) and incidental duodenal bulb inflammation, termed bulbar duodenitis (BD). We conducted a single-center retrospective cohort study and recorded demographics, clinical presentation, endoscopic, and histological findings. BD was observed at the initial endoscopy in 12 cases (36%) and at a subsequent endoscopy in the remainder. Bulbar histology was usually a mix of chronic and eosinophilic inflammation. Patients were more likely to have active EoE (n = 31, 96.9%) at time of BD diagnosis. Our data indicate that the duodenal bulb of children with EoE should be carefully examined at each endoscopy and mucosal biopsies considered. Larger studies are needed to explore this association.

Abstract
In 2022, the US Food and Drug Administration approved dupilumab for treatment of eosinophilic esophagitis (EoE). The aims of this study were to report physician and patient perspectives on initiating dupilumab. A 2-pronged approach was used: (1) data on physician prescribing practices was gathered via retrospective chart review of EoE patients prescribed dupilumab and (2) pediatric patients on dupilumab were approached to complete a questionnaire regarding reasons for initiation. During this time, 42 patients were prescribed dupilumab. From the physician's perspective, the primary reasons for dupilumab included nonresponse to topical corticosteroids (TCS) (52%), nonadherence (28%), adverse effects (10%), or to treat multiple atopic diseases (5%). The median dupilumab initiation time, from day prescribed to first injection, was 37 days [interquartile range (IQR) 37]. Almost all required prior authorization (PA) (98%), while 17% required letter of appeal and 2% required peer-to-peer. Fifteen patients (36%) completed the questionnaire portion of the study. From the patient's perspective, the primary reasons for dupilumab initiation included nonresponse to TCS (27%), nonadherence to TCS (27%), concern about adverse effects of TCS (7%), and treatment of multiple atopic diseases (33%). In conclusion, physicians are prescribing dupilumab primarily for nonresponse to TCS and almost all required PA with a long delay to starting dupilumab.

Abstract
Children with eosinophilic esophagitis (EoE) are faced with ongoing treatments that can impact their wellbeing. There are no evidence-based resources that families can implement independently to cope with EoE-related stressors. This study aimed to examine acceptability, feasibility, and preliminary outcomes of the newly developed Cellie Coping Kit for Children with EoE intervention. Forty child-caregiver dyads completed a baseline assessment (T1) and initiated the intervention; 30 (75%) child participants and 33 (82.5%) caregivers were retained to follow-up (T2). Of those who completed the T2 assessment, most reported that the intervention was easy to use (>90%) and would recommend the intervention to others (>90%). The intervention was feasible: >70% used the kit, and most indicated they would use it again (>75%). More than half of families reported learning new information and/or coping strategies. No statistically significant changes were identified in comparing T1 and T2 coping and health-related quality of life. These findings suggest that the Cellie Coping Kit for Children with EoE is a promising intervention in that it was well accepted, feasible, and helped many families learn novel strategies on how to manage EoE challenges. Future research should examine how to strengthen the intervention to achieve longer-term targeted outcomes.

Abstract
Background and Aim The DanEoE is a previously described population- and register-based cohort of 236 adult patients with eosinophilic esophagitis (EoE) in a well-defined Danish region with a population of 580 000 and free medical treatment. The aim of the study was to compare the phenotype and treatment response between EoE patients with complications to patients without complications at diagnosis. Methods A retrospective cross-sectional study of the DanEoE cohort's 236 adult EoE patients diagnosed between 2007 and 2017 in the North Denmark Region. Patients were divided into a group who had had complications (dilated or food bolus obstruction [FBO]) before or at the diagnosis, and a group without. Results At the diagnostic endoscopy, 61% had never had a complication, and 39% had either had FBO (n = 77) or been dilated (n = 15). The complicated group had the same mean age at symptom debut (37 [SD = 16] vs 37 [SD = 17] years, P = 1.0), but were diagnosed significantly later with a resulting longer diagnostic delay (13 [SD = 13] vs 7.9 [SD = 11] years, P = 0.01). Almost half of all patients were never treated to symptomatic remission (uncomplicated 40%, complicated 49%). The histological remission was not secured in the majority (uncomplicated 68%, complicated 70%). Despite this, <15% of patients with previous FBO experienced this after the diagnosis. Conclusion In the population-based DanEoE cohort, results indicated that the complicated EoE phenotype was a patient with a 5-year longer diagnostic delay. In the current study, the complication status did not predict the treatment response.

Abstract
Allergic conditions, such as asthma, chronic urticaria, atopic dermatitis (AD), and eosinophilic esophagitis, have long been treated with oral and topical steroids which resulted in negative off-target effects. However, newer biologic medications are increasingly being developed and approved for treatment of these conditions. These medications have a variety of mechanisms of action to target pathophysiology specific to these diseases. As biologics become more targeted, fewer off-target effects are seen improving tolerability for patients as well as expanded options for treatment of these conditions. This review discusses monoclonal antibody therapies (omalizumab, mepolizumab, reslizumab, benralizumab, dupilumab, tezepelumab, and tralokinumab) including their safety and use in asthma, chronic urticaria, AD, and eosinophilic esophagitis.

Higher Body Mass Index Is Associated With Decreased Treatment Response to Topical Steroids in Eosinophilic Esophagitis. Clin Gastroenterol Hepatol 2023; 21:2252-2259.e3. [PMID: 36410644 DOI: 10.1016/j.cgh.2022.11.004] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 11/01/2022] [Accepted: 11/04/2022] [Indexed: 11/21/2022]
Abstract
BACKGROUND & AIMS Understanding which eosinophilic esophagitis (EoE) patients will respond to treatment with topical corticosteroids (tCS) remains challenging, and it is unknown whether obesity impacts treatment response. This study aimed to determine whether treatment outcomes to tCS in EoE patients vary by body mass index (BMI). METHODS This retrospective cohort study of the University of North Carolina EoE Clinicopathologic database assessed subjects age 14 years or older with a new diagnosis of EoE. Their BMI was calculated and histologic, symptom, and endoscopic responses were recorded after tCS treatment. The treatment response of obese (BMI, ≥30 kg/m2) and nonobese EoE status was compared using bivariate and multivariate analyses. RESULTS We identified 296 EoE patients treated with tCS. Baseline characteristics were similar, although obese EoE patients had more heartburn and hiatal hernias. Histologic response was higher for those who were nonobese compared with obese at fewer than 15 (61% vs 47%; P = .049) and 6 or fewer (54% vs 38%; P = .02) eosinophils per high-power field, respectively. In addition, nonobese patients had significantly greater endoscopic and symptomatic responses. On multivariate analysis, increasing BMI was associated independently with decreased histologic response after accounting for age, heartburn, dilation, and hiatal hernia whether BMI was assessed as a continuous variable (adjusted odds ratio [aOR], 0.93; 95% CI, 0.89-0.98), as nonobese vs obese (aOR, 0.38; 95% CI, 0.21-0.68), or in 4 categories (overweight vs normal [aOR, 0.46; 95% CI, 0.26-0.84] or obese vs normal [aOR, 0.26; 95% CI, 0.13-0.51]). CONCLUSIONS As BMI increases in EoE patients, the odds of histologic, symptomatic, and endoscopic responses to tCS decreases, with obese patients having an approximately 40% decrease in odds of response.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is a chronic antigen-mediated eosinophilic inflammatory disease isolated to the esophagus. As a clinicopathologic disorder, a diagnosis of EoE requires a constellation of clinical symptoms of esophageal dysfunction and histologic findings (at least 15 eosinophils/high-powered microscope field (eos/hpf)). Current guidelines no longer require the failure of response to proton pump inhibitor medications to establish a diagnosis of EoE, but continue to suggest the exclusion of other etiologies of esophageal eosinophilia. The treatment goals for EoE are improvement in clinical symptoms, resolution of esophageal eosinophilia and other histologic abnormalities, endoscopic improvement, improved quality of life, improved esophageal function, minimized adverse effects of treatment, and prevention of disease progression and subsequent complications. Currently, there is no cure for EoE, making long-term treatment necessary. Standard treatment modalities include dietary modifications, esophageal dilation, and pharmacologic therapy. Effective pharmacologic therapies include corticosteroids, rapidly emerging biological therapies, and proton pump inhibitor medications. OBJECTIVES To evaluate the efficacy and safety of medical interventions for people with eosinophilic esophagitis. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, ClinicalTrials.gov, and WHO ICTRP to 3 March 2023. SELECTION CRITERIA Randomized controlled trials (RCTs) comparing any medical intervention or food elimination diet for the treatment of eosinophilic esophagitis, either alone or in combination, to any other intervention (including placebo). DATA COLLECTION AND ANALYSIS Pairs of review authors independently selected studies and conducted data extraction and risk of bias assessment. We expressed outcomes as a risk ratio (RR) and as the mean or standardized mean difference (MD/SMD) with 95% confidence interval (CI). We assessed the certainty of the evidence using GRADE. Our primary outcomes were: clinical, histological, and endoscopic improvement, and withdrawals due to adverse events. Secondary outcomes were: serious and total adverse events, and quality of life. MAIN RESULTS We included 41 RCTs with 3253 participants. Eleven studies included pediatric patients while the rest recruited both children and adults. Four studies were in patients with inactive disease while the rest were in patients with active disease. We identified 19 intervention comparisons. In this abstract we present the results of the primary outcomes for the two main comparisons: corticosteroids versus placebo and biologics versus placebo, based on the prespecified outcomes defined of the primary studies. Fourteen studies compared corticosteroids to placebo for induction of remission and the risk of bias for these studies was mostly low. Corticosteroids may lead to slightly better clinical improvement (20% higher), measured dichotomously (risk ratio (RR) 1.74, 95% CI 1.08 to 2.80; 6 studies, 583 participants; number needed to treat for an additional beneficial outcome (NNTB) = 4; low certainty), and may lead to slightly better clinical improvement, measured continuously (standard mean difference (SMD) 0.51, 95% CI 0.17 to 0.85; 5 studies, 475 participants; low certainty). Corticosteroids lead to a large histological improvement (63% higher), measured dichotomously (RR 11.94, 95% CI 6.56 to 21.75; 12 studies, 978 participants; NNTB = 3; high certainty), and may lead to histological improvement, measured continuously (SMD 1.42, 95% CI 1.02 to 1.82; 5 studies, 449 participants; low certainty). Corticosteroids may lead to little to no endoscopic improvement, measured dichotomously (RR 2.60, 95% CI 0.82 to 8.19; 5 studies, 596 participants; low certainty), and may lead to endoscopic improvement, measured continuously (SMD 1.33, 95% CI 0.59 to 2.08; 5 studies, 596 participants; low certainty). Corticosteroids may lead to slightly fewer withdrawals due to adverse events (RR 0.64, 95% CI 0.43 to 0.96; 14 studies, 1032 participants; low certainty). Nine studies compared biologics to placebo for induction of remission. Biologics may result in little to no difference in clinical improvement, measured dichotomously (RR 1.14, 95% CI 0.85 to 1.52; 5 studies, 410 participants; low certainty), and may result in better clinical improvement, measured continuously (SMD 0.50, 95% CI 0.22 to 0.78; 7 studies, 387 participants; moderate certainty). Biologics result in better histological improvement (55% higher), measured dichotomously (RR 6.73, 95% CI 2.58 to 17.52; 8 studies, 925 participants; NNTB = 2; moderate certainty). We could not draw conclusions for this outcome when measured continuously (SMD 1.01, 95% CI 0.36 to 1.66; 6 studies, 370 participants; very low certainty). Biologics may result in little to no difference in endoscopic improvement, measured dichotomously (effect not estimable, low certainty). We cannot draw conclusions for this outcome when measured continuously (SMD 2.79, 95% CI 0.36 to 5.22; 1 study, 11 participants; very low certainty). There may be no difference in withdrawals due to adverse events (RR 1.55, 95% CI 0.88 to 2.74; 8 studies, 792 participants; low certainty). AUTHORS' CONCLUSIONS Corticosteroids (as compared to placebo) may lead to clinical symptom improvement when reported both as dichotomous and continuous outcomes, from the primary study definitions. Corticosteroids lead to a large increase in histological improvement (dichotomous outcome) and may increase histological improvement (continuous outcome) when compared to placebo. Corticosteroids may or may not increase endoscopic improvement (depending on whether the outcome is measured dichotomously or continuously). Withdrawals due to adverse events (dichotomous outcome) may occur less frequently when corticosteroids are compared to placebo. Biologics (as compared to placebo) may not lead to clinical symptom improvement when reported as a dichotomous outcome and may lead to an increase in clinical symptom improvement (as a continuous outcome), from the primary study definitions. Biologics lead to a large increase in histological improvement when reported as a dichotomous outcome, but this is uncertain when reported as a continuous outcome, as compared to placebo. Biologics may not increase endoscopic improvement (dichotomous outcome), but this is uncertain when measured as a continuous outcome. Withdrawals due to adverse events as a dichotomous outcome may occur as frequently when biologics are compared to placebo.

Abstract
Dietary therapy for short- and long-term management of eosinophilic esophagitis is an effective yet poorly understood and underutilized treatment strategy. Despite several prospective trials demonstrating the efficacy of dietary therapies, successful clinical implementation is hampered by the need for a multidisciplinary approach including dietitian support and provider expertise. The availability of these resources is not readily available to most gastroenterologists. Without standardized guidance on starting or completing the diet for gastrointestinal providers and/or consulting dietitians, provider attitudes toward dietary therapy vary greatly depending on familiarity and knowledge gaps in using diet therapy. This review aims to summarize evidence in support of dietary therapy in eosinophilic esophagitis while providing guidance on initiation and implementation of dietary therapy for providers.

Abstract
OBJECTIVE To evaluate the impact of type and dose of swallowed topical steroids (STS) and concurrent steroid therapy on the development and resolution of adrenal insufficiency (AI) in pediatric eosinophilic esophagitis (EoE). METHODS We performed a retrospective case-control study of pediatric EoE subjects in a single tertiary care center, who were treated with STS for at least 3 months and diagnosed with AI based on a peak stimulated cortisol level of <18 µg/dL (500 nmol/L). Steroid forms and doses, and endoscopy data were collected at the time of AI diagnosis and AI resolution or the last known evaluation. Steroid formulations were converted to a fluticasone-equivalent dose for analysis. RESULTS Thirty-two EoE subjects with AI were identified, and 20 had AI resolution, including 12 who remained on lower dose STS. Eight of the 32 patients were also treated with extended-release budesonide (ER budesonide), which resulted in a 7-fold higher total daily steroid dose, and thus were analyzed separately. When the 24 cases that were not on ER budesonide were compared to the 81 controls, no difference was found in the STS dose nor total daily steroid dose, although the inhaled steroid dose had marginal significance. Peak eosinophil counts tended to increase when STS doses were decreased, except in subjects on ER budesonide at AI diagnosis. CONCLUSION Altering the total daily steroid regimen can lead to resolution of AI in patients with EoE, though this may come at the expense of disease control.

Diagnostic role of fractional exhaled nitric oxide in pediatric eosinophilic esophagitis, relationship with gastric and duodenal eosinophils. World J Gastrointest Endosc 2023; 15:407-419. [PMID: 37274554 PMCID: PMC10236975 DOI: 10.4253/wjge.v15.i5.407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 02/05/2023] [Accepted: 04/04/2023] [Indexed: 05/16/2023] Open
Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is an eosinophilic-predominant inflammation of the esophagus diagnosed by upper endoscopy and biopsies. A non-invasive and cost-effective alternative for management of EoE is being researched. Previous studies assessing utility of fractional exhaled nitric oxide (FeNO) in EoE were low powered. None investigated the contribution of eosinophilic inflammation of the stomach and duodenum to FeNO.
AIM To assess the utility of FeNO as a non-invasive biomarker of esophageal eosinophilic inflammation for monitoring disease activity.
METHODS Patients aged 6-21 years undergoing scheduled upper endoscopy with biopsy for suspected EoE were recruited in our observational study. Patients on steroids and with persistent asthma requiring daily controller medication were excluded. FeNO measurements were obtained in duplicate using a chemiluminescence nitric oxide analyzer (NIOX MINO, Aerocrine, Inc.; Stockholm, Sweden) prior to endoscopy. Based on the esophageal peak eosinophil count (PEC)/high power field on biopsy, patients were classified as EoE (PEC ≥ 15) or control (PEC ≤ 14). Mean FeNO levels were correlated with presence or absence of EoE, eosinophil counts on esophageal biopsy, and abnormal downstream eosinophilia in the stomach (PEC ≥ 10) and duodenum (PEC ≥ 20). Wilcoxon rank-sum test, Spearman correlation, and logistic regression were used for analysis. P value < 0.05 was considered significant.
RESULTS We recruited a total of 134 patients, of which 45 were diagnosed with EoE by histopathology. The median interquartile range FeNO level was 17 parts per billion (11-37, range: 7-81) in the EoE group and 12 parts per billion (8-19, range: 5-71) in the control group. After adjusting for atopic diseases, EoE patients had significantly higher FeNO levels as compared to patients without EoE (Z = 3.33, P < 0.001). A weak yet statistically significant positive association was found between the number of esophageal eosinophils and FeNO levels (r = 0.30, P < 0.005). On subgroup analysis within the EoE cohort, higher FeNO levels were noted in patients with abnormal gastric (n = 23, 18 vs 15) and duodenal eosinophilia (n = 28, 21 vs 14); however, the difference was not statistically significant.
CONCLUSION After ruling out atopy as possible confounder, we found significantly higher FeNO levels in the EoE cohort than in the control group.

Genome-wide admixture and association analysis identifies African ancestry-specific risk loci of eosinophilic esophagitis in African Americans. J Allergy Clin Immunol 2023; 151:1337-1350. [PMID: 36400179 PMCID: PMC10164699 DOI: 10.1016/j.jaci.2022.09.040] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 09/17/2022] [Accepted: 09/28/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND Eosinophilic esophagitis (EoE), a chronic allergic inflammatory disease, is linked to multiple genetic risk factors, but studies have focused on populations of European ancestry. Few studies have assessed Black or African American (AA) populations for loci involved in EoE susceptibility. OBJECTIVE We performed admixture mapping (AM) and genome-wide association study (GWAS) of EoE using participants from AA populations. METHODS We conducted AM and GWAS of EoE using 137 EoE cases and 1465 healthy controls from the AA population. Samples were genotyped using molecular evolutionary genetics analysis (MEGA). Genotype imputation was carried out with the Consortium on Asthma Among African-Ancestry Populations in the Americas (CAAPA) reference panel using the Michigan Imputation Server. Global and local ancestry inference was carried out, followed by fine mapping and RNA sequencing. After quality control filtering, over 6,000,000 variants were tested by logistic regression adjusted for sex, age, and global ancestry. RESULTS The global African ancestry proportion was found to be significantly lower among cases than controls (0.751 vs 0.786, P = .012). Case-only AM identified 3 significant loci (9p13.3, 12q24.22-23, and 15q11.2) associated with EoE, of which 12q24.22-23 and 9p13.3 were further replicated in the case-control analysis, with associations observed with African ancestry. Fine mapping and multiomic functional annotations prioritized the variants rs11068264 (FBXW8) and rs7307331 (VSIG10) at 12q24.23 and rs2297879 (ARHGEF39) at 9p13.3. GWAS identified 1 genome-wide significant locus at chromosome 1p22.3 (rs17131726, DDAH1) and 10 other suggestive loci. Most GWAS variants were low-frequency African ancestry-specific variants. RNA sequencing revealed that esophageal DDAH1 and VSIG10 were downregulated and ARHGEF39 upregulated among EoE cases. CONCLUSIONS GWAS and AM for EoE in AA revealed that African ancestry-specific genetic susceptibility loci exist at 1p22.3, 9p13.3, and 12q24.23, providing evidence of ancestry-specific inheritance of EoE. More independent genetic studies of different ancestries for EoE are needed.
