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
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.

Determinant factors for first-line treatment choice and effectiveness in pediatric eosinophilic esophagitis: an analysis of the EUREOS EoE CONNECT registry. Eur J Pediatr 2024; 183:3567-3578. [PMID: 38819501 PMCID: PMC11263422 DOI: 10.1007/s00431-024-05618-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2024] [Revised: 05/03/2024] [Accepted: 05/17/2024] [Indexed: 06/01/2024]
Abstract
This study compared short-term effectiveness of proton pump inhibitors (PPI), swallowed topical corticosteroids (STC), and dietary therapies in reversing clinical and histological features in pediatric patients with eosinophilic esophagitits (EoE). Determinants for treatment choice and PPI therapy effectiveness were also assessed. A cross-sectional study analysis of patients under 18 years old recruited onto the multicenter EoE CONNECT registry was performed. Clinico-histological response was defined as symptomatic improvement plus a peak eosinophil count below 15 per high-power field after treatment. Effectiveness of first-line options used in monotherapy was compared. Overall, 393 patients (64% adolescents) receiving PPI, STC, or dietary monotherapy to induce EoE remission were identified. PPI was the preferred option (71.5%), despite STC providing the highest clinico-histological response rates (66%) compared to PPI (44%) and diet (42%). Logistic regression identified fibrotic features and recruitment at Italian sites independently associated to first-line STC treatment; age under 12 associated to dietary therapy over other options. Analysis of 262 patients in whom PPI effectiveness was evaluated after median (IQR) 96 (70-145) days showed that this effectiveness was significantly associated with management at pediatric facilities and use of high PPI doses. Among PPI responders, decrease in rings and structures in endoscopy from baseline was documented, with EREFS fibrotic subscore for rings also decreasing among responders (0.27 ± 0.63 vs. 0.05 ± 0.22, p < 0.001). Conclusion: Initial therapy choice for EoE depends on endoscopic phenotype, patient's age, and patients' origin. High PPI doses and treatment in pediatric facilities significantly determined effectiveness, and reversed fibrotic endoscopic features among responders. What is Known: • Proton pump inhibitors are widely used to induce and maintain remission in EoE in real practice, despite other first-line alternative therapies possibly providing higher effectiveness. What is New: • Proton pump inhibitors represent up to two-thirds of first-line monotherapies used to induce EoE remission in pediatric and adolescent patients with EoE. The choice of STC as first-line treatment for EoE was significantly associated with fibrotic features at baseline endoscopy and recruitment in Italian centers; age less than 12 years was associated with dietary therapy. • PPI effectiveness was found to be determined by use of high doses, attendance at pediatric facilities, presenting inflammatory instead of fibrotic or mixed phenotypes, and younger age. Among responders, PPI therapy reversed both inflammatory and fibrotic features of EoE after short-term treatment.

Abstract
Eosinophilic esophagitis (EoE) is a chronic, allergen-mediated, type-2 inflammatory disease with the potential to significantly impact an individual's quality of life. Conventional treatments often result in varied responses, prompting the need for novel therapeutic approaches. We present the case of a 19-year-old male with a medical history marked by eosinophilic esophagitis, severe atopic dermatitis (AD), asthma, and allergic rhinitis. Despite undergoing diverse topical and systemic interventions to address his AD and EoE, the patient's symptoms persisted. However, following the initiation of dupilumab therapy-a dual IL-4 and IL-13 receptor antagonist-the patient experienced a substantial reduction in his Eczema Area and Severity Index score. Notably, a marked improvement was also seen regarding his symptoms of eosinophilic esophagitis. A subsequent esophageal biopsy revealed a significant decrease in eosinophilic inflammation, consistent with established clinical and histologic remission criteria. These findings corroborate the patient's reported relief from symptoms. This case underscores the potential efficacy of dupilumab as a promising therapeutic agent in managing eosinophilic esophagitis. Dupilumab offers a dual benefit of alleviating symptoms and achieving histologic and clinical remission. This novel approach presents a noteworthy advancement in the treatment of EoE.

Abstract
BACKGROUND A combination of proton-pump inhibitors (PPI) and topical steroids (TS) is used to treat children with eosinophilic esophagitis (EoE). However, a subset of children do not respond to this combination therapy. We aimed to identify the esophageal transcriptional, cell composition, and microbial differences between the non-responders (EoE-PPI-TSnr; n = 7) and responders (EoE-PPI-TSr; n = 7) to the combination therapy for EoE and controls (n = 9) using metatranscriptomics. METHODS Differential gene expression analysis was used to identify transcriptional differences, validated using the EoE diagnostic panel (EDP). Deconvolution analysis was performed to identify differences in their cell type composition. Microbiome analysis was conducted from esophageal biopsies RNAseq data, and microbial abundance was correlated with esophageal gene expression. RESULTS In all, 3164 upregulated and 3154 downregulated genes distinguished EoE-PPI-TSnr from EoE-PPI-TSr. Eosinophilic inflammatory response, cytokine signaling, and collagen formation pathways were significantly upregulated in EoE-PPI-TSnr. There was a 56% overlap in dysregulated genes between EoE-PPI-TSnr and EDP, with a perfect agreement in the directionality of modulation. Eosinophils, dendritic cells (DCs), immature DCs, megakaryocytic-erythroid progenitors, and T helper type 1 cells were significantly higher in EoE-PPI-TSnr. There was no significant difference in microbiome diversity. The relative abundance of Fusobacterium sp. and Acinetobacter sp. notably differed in EoE-PPI-TSnr and correlated with the key pathways. CONCLUSION Our results provide critical insights into the molecular, cellular, and microbial factors associated with the lack of response to PPI and TS combination therapy in children with EoE. This study advances our understanding of the pathobiology of EoE while guiding personalized treatment strategies.

J Pediatr Gastroenterol Nutr 2024; 79:92-99. [PMID: 38803200 DOI: 10.1002/jpn3.12273] [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: 01/31/2023] [Revised: 04/27/2024] [Accepted: 05/15/2024] [Indexed: 05/29/2024]
Abstract
OBJECTIVES Oral viscous budesonide (OVB) is a common medication used to treat eosinophilic esophagitis (EoE). It is typically mixed with Splenda to produce a slurry, but other delivery vehicles have been used in clinical practice. We aimed to evaluate outcomes of pediatric EoE patients treated with OVB using different drug delivery vehicles. METHODS We performed a retrospective chart review of pediatric EoE patients treated with OVB. The primary aim was to evaluate rates of histologic remission (defined by <15 eosinophils per high power field in both mid and distal esophagus) after 6-12 weeks of OVB treatment for each delivery vehicle. Secondary aims were to evaluate histologic response and endoscopic response and remission of different delivery vehicles, and to compare the efficacy of different treatment regimens. RESULTS A total of 111 patients were included in the study. Median treatment duration was 3.4 months. Overall rate of histologic remission with OVB was 52.6%. There was no difference in rates of histologic remission (p = 0.313) or response (p = 0.195 and p = 0.681 in mid and distal esophagus, respectively) among the different vehicle types or treatment regimens. Similarly, there was no difference in endoscopic remission and response among the different vehicle types (p = 0.853 and p = 0.727) or treatment regimens (p = 0.244 and p = 0.157). Patients who achieve histologic remission were more likely to be non-Hispanic Caucasian. CONCLUSION Our findings suggest there is no difference in histologic and endoscopic outcomes with various delivery vehicles or combination therapy with OVB in the treatment of EoE. More palatable and cost-effective vehicles can be used to treat EoE.

Abstract
BACKGROUND Swallowed topical corticosteroids (tC) are common therapy for patients with eosinophilic esophagitis (EoE). Widely heterogeneous results have occurred due to their active ingredients, formulations and doses. OBJECTIVE To assess the effectiveness of topical corticosteroid therapy for EoE in real-world practice. METHODS Cross-sectional study analysis of the multicentre EoE CONNECT registry. Clinical remission was defined as a decrease of ≥50% in dysphagia symptom scores; histological remission was defined as a peak eosinophil count below 15 per high-power field. The effectiveness in achieving clinico-histological remission (CHR) was compared for the main tC formulations. RESULTS Overall, data on 1456 prescriptions of tC in monotherapy used in 866 individual patients were assessed. Of those, 904 prescriptions with data on formulation were employed for the induction of remission; 234 reduced a previously effective dose for maintenance. Fluticasone propionate formulations dominated the first-line treatment, while budesonide was more common in later therapies. A swallowed nasal drop suspension was the most common formulation of fluticasone propionate. Doses ≥0.8 mg/day provided a 65% CHR rate and were superior to lower doses. Oral viscous solution prepared by a pharmacist was the most common prescription of budesonide; 4 mg/day provided no benefit over 2 mg/day (CHR rated being 72% and 80%, respectively). A multivariate analysis revealed budesonide orodispersible tablets as the most effective therapy (OR 18.9, p < 0.001); use of higher doses (OR 4.3, p = 0.03) and lower symptom scores (OR 0.9, p = 0.01) were also determinants of effectiveness. CONCLUSION Reduced symptom severity, use of high doses, and use of budesonide orodispersible tablets particularly were all independent predictors of tC effectiveness.

Histological Outcomes of Pharmacological Interventions in Eosinophilic Esophagitis for Adults and Children: A Network Meta-analysis of Randomized Controlled Trials. J Clin Gastroenterol 2024:00004836-990000000-00296.

Abstract
INTRODUCTION Multiple pharmacological interventions have been studied for managing eosinophilic esophagitis (EoE). We performed a comprehensive systematic review and network meta-analysis of all available randomized controlled trials (RCT) to assess the efficacy and safety of these interventions in EoE in adults and children. METHODS We performed a comprehensive review of Embase, PubMed, MEDLINE OVID, Cochrane CENTRAL, and Web of Science through May 10, 2023. We performed frequentist approach network meta-analysis using random effects model. We calculated the odds ratio (OR) with 95% CI for dichotomous outcomes. RESULTS Our search yielded 25 RCTs with 25 discrete interventions and 2067 patients. Compared with placebo, the following interventions improved histology (using study definitions) in decreasing order on ranking: orodispersible budesonide (ODB) low dose, ODB high dose, oral viscous budesonide (OVB) high dose, fluticasone tablet 1.5 mg twice daily, fluticasone 3 mg twice daily, esomeprazole, dupilumab every 2 weeks, dupilumab weekly, OVB medium dose, fluticasone 3 mg daily, cendakimab 180 mg, prednisone, swallowed fluticasone, fluticasone tablet 1.5 mg daily, OVB low dose, reslizumab 3 mg/kg, reslizumab 1 mg/kg, and reslizumab 2 mg/kg. CONCLUSIONS Network meta-analysis demonstrates histological efficacy of multiple medications for EoE. Because of the heterogeneity and large effect size, we recommend more trials comparing pharmacotherapeutic interventions with each other and placebo. An important limitation of this study is absence of clinical efficacy data due to insufficient data. Other limitations include heterogeneity of operator, population, and outcome analysis.

Abstract
Objectives The aim of the study was to characterize the circulating immunome of patients with EoE before and after proton pump inhibitor (PPI) treatment in order to identify potential non-invasive biomarkers of treatment response. Methods PBMCs from 19 healthy controls and 24 EoE patients were studied using a 39-plex spectral cytometry panel. The plasmacytoid dendritic cell (pDC) population was differentially characterized by spectral cytometry analysis and immunofluorescence assays in esophageal biopsies from 7 healthy controls and 13 EoE patients. Results Interestingly, EoE patients at baseline had lower levels of circulating pDC compared with controls. Before treatment, patients with EoE who responded to PPI therapy had higher levels of circulating pDC and classical monocytes, compared with non-responders. Moreover, following PPI therapy pDC levels were increased in all EoE patients, while normal levels were only restored in PPI-responding patients. Finally, circulating pDC levels inversely correlated with peak eosinophil count and pDC count in esophageal biopsies. The number of tissue pDCs significantly increased during active EoE, being even higher in non-responder patients when compared to responder patients pre-PPI. pDC levels decreased after PPI intake, being further restored almost to control levels in responder patients post-PPI. Conclusions We hereby describe a unique immune fingerprint of EoE patients at diagnosis. Moreover, circulating pDC may be also used as a novel non-invasive biomarker to predict subsequent response to PPI treatment.

Proton-Pump Inhibitors in Eosinophilic Esophagitis: A Review Focused on the Role of Pharmacogenetics. Pharmaceutics 2024; 16:487. [PMID: 38675148 PMCID: PMC11054109 DOI: 10.3390/pharmaceutics16040487] [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: 02/23/2024] [Revised: 03/22/2024] [Accepted: 03/25/2024] [Indexed: 04/28/2024] Open
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
Proton pump inhibitors (PPIs) are the first-line drug for eosinophilic esophagitis (EoE), although it is estimated that there is a lack of histological remission in 50% of patients. This research aimed to identify pharmacogenetic biomarkers predictive of PPI effectiveness and to study their association with disease features. Peak eosinophil count (PEC) and the endoscopic reference score (EREFS) were determined before and after an eight-week PPI course in 28 EoE patients. The impact of the signal transducer and activator of transcription 6 (STAT6), CYP2C19, CYP3A4, CYP3A5, and ABCB1 genetic variations on baseline PEC and EREFS, their reduction and histological response, and on EoE symptoms and comorbidities was analyzed. PEC reduction was higher in omeprazole-treated patients (92.5%) compared to other PPIs (57.9%, p = 0.003). STAT6 rs12368672 (g.18453G>C) G/G genotype showed higher baseline PEC values compared to G/C and C/C genotypes (83.2 vs. 52.9, p = 0.027). EREFS reduction in STAT6 rs12368672 G/G and G/C genotypes was higher than in the C/C genotype (36.7% vs. -75.0% p = 0.011). However, significance was lost after Bonferroni correction. Heartburn incidence was higher in STAT6 rs167769 (g.27148G>A) G/G patients compared to G/A (54.55% vs. 11.77%, p = 0.030). STAT6 rs12368672G>C and rs167769G>A variants might have a relevant impact on EoE status and PPI response. Further research is warranted to clarify the clinical relevance of these variants.

[PMID: 38667506 PMCID: PMC11052511 DOI: 10.3390/medicines11040008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 01/11/2024] [Accepted: 03/18/2024] [Indexed: 04/28/2024]
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
OBJECTIVE To assess the effect of long-term dupilumab on histological, symptomatic and endoscopic aspects of eosinophilic oesophagitis (EoE) in adolescent and adult patients with and without prior use of swallowed topical corticosteroids (STC) or prior inadequate response, intolerance or contraindication to STC. DESIGN Pre-specified analysis of data from the phase 3 LIBERTY EoE TREET study on patients who received dupilumab 300 mg once a week or placebo for 24 weeks (W24) in parts A and B, and an additional 28 weeks (W52) in part C. Patients were categorised as with/without prior STC use and with/without inadequate/intolerance/contraindication to STC. The proportion of patients achieving ≤6 eosinophils per high-power field (eos/hpf), absolute change in Dysphagia Symptom Questionnaire (DSQ) score, mean change in Endoscopic Reference Score and Histologic Scoring System grade/stage scores were assessed for each subgroup. RESULTS Regardless of prior STC use, dupilumab increased the proportion of patients achieving ≤6 eos/hpf and improved DSQ score versus placebo at W24, with improvements maintained or improved at W52. The DSQ score and the proportion of patients achieving ≤6 eos/hpf after switching from placebo to dupilumab at W24 were similar to those observed in the dupilumab group at W24, regardless of prior STC use or inadequate/intolerance/contraindication to STC. Improvements in other outcomes with dupilumab were similar in patients with/without prior STC use or inadequate/intolerance/contraindication to STC. CONCLUSION Dupilumab 300 mg once a week demonstrated efficacy and was well tolerated in patients with EoE regardless of prior STC use or inadequate response, intolerance and/or contraindication to STC. TRIAL REGISTRATION NUMBER NCT03633617.

Lee CJ, Dellon ES. Real-World Efficacy of Dupilumab in Severe, Treatment-Refractory, and Fibrostenotic Patients With Eosinophilic Esophagitis. Clin Gastroenterol Hepatol 2024; 22:252-258. [PMID: 37660770 DOI: 10.1016/j.cgh.2023.08.015] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 07/22/2023] [Accepted: 08/10/2023] [Indexed: 09/05/2023]
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
INTRODUCTION Eosinophilic esophagitis (EoE) is a chronic immune-mediated disease of the esophagus with increasing incidence and dysphagia as the main symptom. The management of suspected or known EoE by Austrian endoscopists has not been investigated yet. METHODS A web-based survey with 13 questions about the management of EoE was sent to endoscopists via the Austrian Society of Gastroenterology and Hepatology (ÖGGH). RESULTS A total of 222 endoscopists (74% gastroenterologists, 23% surgeons, and 2% pediatricians; 68% working in a hospital) from all 9 states participated. In patients with dysphagia but a normal appearing esophagus, 85% of respondents reported always taking biopsies; however, surgeons were less likely to obtain biopsies compared to gastroenterologists ("always" 69% vs. 90%, "sometimes" 29% vs. 10%, "never" 2% vs. 0%, p < 0.001). The approved budesonide orodispersible tablet is the preferred first-line drug used in EoE, ahead of proton pump inhibitors (PPI). Only 65% of participants monitor the patients by endoscopy and histology after 12 weeks of induction therapy, 26% do not continue maintenance therapy, and 22% monitor patients only when symptomatic. CONCLUSION The vast majority of Austrian endoscopists adhere to the European and US guidelines in cases of suspected EoE. In contrast, despite the chronic disease course, a significant percentage of providers indicate not to use maintenance therapy and monitor the patients routinely.

Melgaard D, Hansen AB, Pedersen C, Sandholm E, Hansen TB, Frandsen LT, Krarup AL. An improved guideline adherence and PPI efficacy has been accompanied by a decrease in diagnostic delay, and strictures before diagnosis of eosinophilic esophagitis in the North Denmark Region - a retrospective registry study of the DanEoE cohorts. Clin Res Hepatol Gastroenterol 2023; 47:102159. [PMID: 37307949 DOI: 10.1016/j.clinre.2023.102159] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 06/07/2023] [Accepted: 06/09/2023] [Indexed: 06/14/2023]
Abstract
BACKGROUND In the North Denmark Region an increased awareness of eosinophilic esophagitis (EoE) was observed after 2011 where a regional biopsy guideline was implemented. This resulted in an increased awareness of EoE and a 50-fold increase in the incidence of EoE patients between 2007-2017. AIMS The aims of this study were to examine the progress in diagnostic delay, complications, PPI treatment, and follow up since 2017 in Danish patients with eosinophilic esophagitis. MATERIALS AND METHODS This was a retrospective registry- and population-based cohort study (DanEoE2 cohort) including 346 adult patients with esophageal eosinophilia diagnosed between 2018-2021 in the North Denmark Region. The DanEoE2 cohort included all possible EoE patients by using the Danish Patho-histology registry based on the SNOMED-system. The data was analyzed and compared to the DanEoE cohort (2007-2017). RESULTS The diagnostic delay of EoE patients diagnosed between 2018-2021 in the North Denmark Region had decreased with a median of 1.5 years (5.5 (2.0;12) years versus 4.0 (1.0;12) years, p=0.03). Strictures before diagnosis had decreased 8.4 % (11.6% versus 3.2%, p=0.003). The number of patients started on high-dose PPI increased (56% versus 88%, p<0.001). An intensified awareness regarding national guidelines and follow-up was observed as an increase in the number of histological follow up (67% versus 74%, p=0.05). CONCLUSIONS Comparisons of the DanEoE cohorts showed a decrease in diagnostic delay, a decrease in stricture formation before diagnosis, and an improved guideline adherence after 2017. Future studies are needed to assess if symptomatic or histological remission on PPI treatment is more capable of predicting a patient's risk of developing complications.

Abstract
BACKGROUND Direct comparisons of childhood- and adulthood-onset eosinophilic esophagitis (EoE) are scarce. AIM To compare disease characteristics, endoscopic and histological features, allergic concomitances and therapeutic choices across ages. METHODS Cross-sectional analysis of the EoE CONNECT registry. RESULTS The adulthood-onset cohort (those diagnosed at ≥18y) comprised 1044 patients and the childhood-onset cohort (patients diagnosed at <18 y), 254. Vomiting, nausea, chest and abdominal pain, weight loss, slow eating and food aversion were significantly more frequent in children; dysphagia, food bolus impaction and heartburn predominated in adults. A family history of EoE was present in 16% of pediatric and 8.2% of adult patients (p<0.001). Concomitant atopic diseases did not vary across ages. Median±IQR diagnostic delay (years) from symptom onset was higher in adults (2.7 ± 6.1) than in children (1 ± 2.1; p<0.001). Esophageal strictures and rings predominated in adults (p<0.001), who underwent esophageal dilation more commonly (p = 0.011). Inflammatory EoE phenotypes were more common in children (p = 0.001), who also presented higher eosinophil counts in biopsies (p = 0.015) and EREFS scores (p = 0.017). Despite PPI predominating as initial therapy in all cohorts, dietary therapy and swallowed topical corticosteroids were more frequently prescribed in children (p<0.001). CONCLUSIONS Childhood-onset EoE has differential characteristics compared with adulthood-onset, but similar response to treatment.

Abstract
Eosinophilic esophagitis (EoE) is a chronic, antigen-mediated disease of the esophagus characterized by symptoms of esophageal dysfunction and an eosinophil-predominant inflammation. Seminal reports identified the role of food allergens in the pathogenesis of the disease by demonstrating that food avoidance could lead to the resolution of esophageal eosinophilia in EoE patients. Although pharmacological treatments for EoE are increasingly being investigated, the exclusion of trigger foods from the diet still represents a valuable option for patients to achieve and maintain disease remission without drugs. Food elimination diets are variegated, and one size does not fit all. Accordingly, before starting any elimination diet, patients' characteristics should be thoroughly evaluated, and a rigorous management plan should be defined. This review provides practical tips and considerations to succeed in the management of EoE patients undergoing food elimination diets, as well as recent advances and future perspectives on food avoidance strategies.

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

Abstract
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
INTRODUCTION Despite effective dietary treatments, physicians prefer medications for eosinophilic esophagitis (EoE). METHODS We conducted a web-based survey of providers to assess the perceived effectiveness, practice patterns, and barriers to EoE dietary therapy. RESULTS Providers view diet as the least effective treatment. The greatest barrier was the belief that patients are disinterested and unlikely to adhere (58%). With less access to dietitians (56%), nonacademic providers often manage diets without dietitian guidance (41%). DISCUSSION Given high patient acceptance for diets and multiple treatment options for EoE, clinicians need evidence-based knowledge on EoE diets, access to dietitians, and awareness of patient preferences.

Abstract
OBJECTIVE Eosinophilic esophagitis (EoE) is an immune-mediated inflammatory disease characterized by eosinophilic infiltration of esophageal tissue. Subtyping of EoE patients could be useful in predicting therapeutic response. We propose clinical subtypes, apply them to our pediatric EoE population retrospectively, and assess therapy choices and remission at one year. METHODS A retrospective chart review of pediatric patients diagnosed with EoE was conducted. Patients were grouped into proposed subtypes (severe, allergic, fibrostenotic, inflammatory, unclassified) based on presenting characteristics. The primary outcome was histologic remission, which was defined <15 eosinophils/high-powered-field (hpf) at the closest visit 1 year postdiagnosis. RESULTS Subtyping was possible in 242 of 256 patients and follow-up histological data were available in 75 subjects. The majority had an overlap in phenotype with 17% severe, 77% allergic, 15% fibrostenotic, 60% inflammatory, and 5% unclassified, whereas 45% of the cohort were assigned to a unique subtype. At 1 year, 43/75 (57%) of patients achieved histologic remission, with an overall average decrease of 33 (IQR -47, -12) eosinophils/hpf across the entire cohort. There was no difference in remission rates among subtypes. First-line therapy review revealed higher rates of proton pump inhibitor (PPI) ± topical steroids utilization in severe patients, while topical steroids were prescribed preferentially over dietary therapy in the fibrostenotic subtype. CONCLUSION There were no observed differences in remission rates at 1 year among clinically defined subtypes of EoE, although this could be attributed to overlapping subtypes. Most patients responded well to medical therapy. Larger scale prospective studies designed to subtype patients and protocolize treatment may help personalize the approach to EoE management.

Abstract
OBJECTIVES Few pediatric data on phenotypic aspects of eosinophilic esophagitis (EoE) are available. The pEEr registry was developed to prospectively characterize children with EoE from Europe and Israel. METHODS pEEr is an ongoing prospective registry enrolling children with esophageal eosinophilia (≥15 eos/HPF). Anonymized data were collected from 19 pediatric centers. Data regarding demographics, clinical manifestations, endoscopy, histology, and therapies were collected. RESULTS A total of 582 subjects (61% male) were analyzed. The median age at diagnosis was 10.5 years [interquartile range (IQR): 5.7-17.7], whereas the age at symptom onset was 9.2 years (IQR: 4.3-16.4), resulting in a median diagnostic delay of 1.2 years (IQR: 0.7-2.3). The diagnostic delay was longer below age <6 years. Shorter diagnostic delays were associated with the presence of food allergy or a family history for EoE. Symptoms varied by age with dysphagia and food impaction more common in adolescents, while vomiting and failure to thrive more common in younger children ( P < 0.001). Among endoscopic findings, esophageal rings were more common in adolescents, whereas exudates were more frequent in younger children( P < 0.001). Patients who responded to proton pump inhibitors (PPIs) were more likely to be older, males, and less often presented severe endoscopic findings. Patients unresponsive to PPIs received topical steroids (40%), elimination diet (41%), or a combined therapy (19%). CONCLUSIONS EoE findings vary according to age in pediatric EoE. Young children are commonly characterized by non-specific symptoms, atopic dermatitis, food allergy, and inflammatory endoscopic lesions. Adolescents usually have dysphagia or food impaction, fibrostenotic lesions, and a better PPI response.

Abstract
BACKGROUND Cow's milk protein is the main food trigger for eosinophilic oesophagitis (EoE) in children and adults and should be continuously avoided once identified as such. AIMS To evaluate tolerance of sterilised cow's milk (boiled instead of UHT processing) with regard to maintenance of EoE remission, health-related quality of life (HRQoL), nutritional intake and allergic sensitisation in patients of all ages with milk-triggered EoE METHODS: We prospectively recruited patients in whom cow's milk was demonstrated to trigger EoE after an empirical food elimination diet-based study. They were given 200 ml of sterilised cow's milk twice daily for 8 weeks. Endoscopic assessment, peak eosinophil counts, oesophageal-related symptoms, HRQoL, blood eosinophils, eosinophil cationic protein (ECP), skin prick test and serum total and specific immunoglobulin E (IgE) to major milk proteins were monitored before and after sterilised milk intake. RESULTS Eighteen patients (13 male) in EoE remission underwent a sterilised milk challenge. Twelve maintained EoE remission (<15 eos/hpf) while EoE recurred in the remainder. Endoscopic appearances deteriorated in non-tolerant patients. HRQoL scored well at baseline and was maintained among patients tolerant to sterilised milk, but deteriorated in reactive ones. No significant changes in blood eosinophil count, ECP, tryptase or total and milk-specific IgE serum levels were observed from baseline. However, cow's milk-specific IgE increased slightly in non-tolerant patients. Clinical and histological remission were maintained in patients who regularly consumed sterilised milk for 1 year. CONCLUSION Sterilised milk did not trigger EoE in two-thirds of patients with documented milk-induced EoE, in either the short or long term.

Abstract
INTRODUCTION Dietary and pharmacological (proton pump inhibitors, swallowed topical corticosteroids) therapies are effective for induction of clinical and histological remission of eosinophilic esophagitis. However, data evaluating their long-term efficacy and safety is limited. AREAS COVERED Since eosinophilic esophagitis is chronic, clinical, endoscopic, and histological features usually recur when successful treatments are stopped. In untreated patients, persistent esophageal eosinophilic inflammation may progress to fibrostenosis over time, giving place to strictures and narrow-caliber esophagi. This article comprehensively reviews available data on long-term maintenance of eosinophilic esophagitis with pharmacological and dietary treatment. It also discusses limitations re: available literature and outlines data gaps on adherence to therapy and monitoring disease activity in the long-term. EXPERT OPINION Evidence indicates that long-term maintenance therapy may decrease the risk of esophageal stricture, food bolus impaction, and need for dilation in patients with eosinophilic esophagitis. Further knowledge on eosinophilic esophagitis phenotypes is needed to ascertain who will benefit best from sustained therapy. Unanswered questions include an adequate definition for sustained remission, best strategies for maintenance drugs and diets, enhancement of treatment adherence, and proper monitoring for long-term surveillance.

Abstract
PURPOSE Data on eosinophilic esophagitis (EoE) in South America is scarce. Moreover, no studies are available in Ecuador. We evaluated the clinical, endoscopic, and histological characteristics of Ecuadorian children with EoE. METHODS Medical records of 2,711 children who underwent upper gastrointestinal endoscopy (UGE) between 2009 and 2020 at Hospital Metropolitano de Quito, Ecuador were reviewed. Esophageal mucosal biopsies were obtained from 72 patients and the features of 35 children with EoE were described. EoE was diagnosed when there were more than 15 eosinophils in the esophagus, per high power field. RESULTS EoE was diagnosed in 35 children (9.4±4.5 years) with a male predominance (74%). Abdominal pain (51.4%) and vomiting (31.4%) were dominant symptoms. A history of allergic diseases was noted in 47.1% of the children, which mainly included allergic rhinitis (37.1%) and atopic dermatitis (11.4%). The most common endoscopic findings were furrowing (82.9%) and edema (74.3%). All patients were initially treated with proton-pump inhibitors (PPIs). Those who did not respond to PPIs received steroids (5.7%) and diet therapy (5.7%), and five patients were referred to an allergist. Clinical and histological resolution was observed in 65% of the patients who underwent a second UGE after 6-8 weeks of PPI. CONCLUSION Our study describes the clinical features of pediatric EoE in Ecuador. This is the first retrospective study in Ecuador that describes the clinical, endoscopic, and histological manifestations of EoE in a small pediatric population. Almost half of the children who underwent a biopsy had EoE.

Abstract
PURPOSE OF REVIEW Management for patients with refractory eosinophilic esophagitis (EoE) remains a clinical challenge. This review aims to define refractory EoE, explore rates and reasons for nonresponse, and discuss the evidence that informs the approach to these patients. RECENT FINDINGS Many patients will fail first-line therapies for EoE. Longer duration of therapy can increase response rates, and initial nonresponders may respond to alternative first-line therapies. There are ongoing clinical trials evaluating novel therapeutics that hold promise for the future of EoE management. Increasingly, there is recognition of the contribution of oesophageal hypervigilance, symptom-specific anxiety, abnormal motility and oesophageal remodelling to ongoing clinical symptoms in patients with EoE. SUMMARY For refractory EoE, clinicians should first assess for adherence to treatment, adequate dosing and correct administration. Extending initial trials of therapy or switching to an alternative first-line therapy can increase rates of remission. Patients who are refractory to first-line therapy can consider elemental diets, combination therapy or clinical trials of new therapeutic agents. Patients with histologic remission but ongoing symptoms should be evaluated for fibrostenotic disease with EGD, barium esophagram or the functional luminal imaging probe (FLIP) and should be assessed for the possibility of oesophageal hypervigilance.

Abstract
Introduction of proton pump inhibitor (PPI) therapy into clinical practice has revolutionized treatment approach to acid-related diseases. With its clinical success came a widespread use of PPI therapy. Subsequently, several studies found that PPIs were oftentimes overprescribed in primary care and emergency setting, likely attributed to seemingly low side-effect profile and physicians having low threshold to initiate therapy. However, now there is a growing concern over PPI side-effect profile among both patients and providers. We would like to bring more awareness to the currently available guidelines on PPI use, discuss clinical indications for PPIs and the evidence behind the reported side-effects. We hope that increased awareness of proper PPI use will make the initiation or continuation of therapy a well informed and an evidence-based decision between patient and physician. We also hope that discussing evidence behind the reported side-effect profile will help clarify the growing concerns over PPI therapy.

Abstract
Background Poor adherence to clinical practice guidelines for eosinophilic esophagitis (EoE) has been described and the diagnostic delay of the disease continues to be unacceptable in many settings. Objective To analyze the impact of improved knowledge provided by the successive international clinical practice guidelines on reducing diagnostic delay and improving the diagnostic process for European patients with EoE. Methods Cross‐sectional analysis of the EoE CONNECT registry based on clinical practice. Time periods defined by the publication dates of four major sets of guidelines over 10 years were considered. Patients were grouped per time period according to date of symptom onset. Results Data from 1,132 patients was analyzed and median (IQR) diagnostic delay in the whole series was 2.1 (0.7‐6.2) years. This gradually decreased over time with subsequent release of new guidelines (p < 0.001), from 12.7 years up to 2007 to 0.7 years after 2017. The proportion of patients with stricturing of mixed phenotypes at the point of EoE diagnosis also decreased over time (41.3% vs. 16%; p < 0.001), as did EREFS scores. The fibrotic sub‐score decreased from a median (IQR) of 2 (1‐2) to 0 (0‐1) when patients whose symptoms started up to 2007 and after 2017 were compared (p < 0.001). In parallel, symptoms measured with the Dysphagia Symptoms Score reduced significantly when patients with symptoms starting before 2007 and after 2012 were compared. A reduction in the number of endoscopies patients underwent before the one that achieved an EoE diagnosis, and the use of allergy testing as part of the diagnostic workout of EoE, also reduced significantly over time (p = 0.010 and p < 0.001, respectively). Conclusion The diagnostic work‐up of EoE patients improved substantially over time at the European sites contributing to EoE CONNECT, with a dramatic reduction in diagnostic delay.

Abstract
INTRODUCTION Patients with acid-related disorders (ARDs) of the upper digestive tract remain highly prevalent and need to be continuously investigated to improve their management. AREAS COVERED This review provides a summary of the most recent advancements in the treatment of ARDs with particular focus on the new drugs available to overcome the unmet needs of traditional therapies. EXPERT OPINION Proton pump inhibitors remain the best therapy in treating ARDs, but a consistent proportion of these patients continues to present mucosal lesions or to experience symptoms despite treatment. These cases pertain mainly to the most severe forms of erosive esophagitis or to non-erosive reflux disease. Also, the increasing rate of patients with H. pylori infection not responding to eradication therapy represents a difficult clinical condition. The recent advent of a new class of antisecretory drugs, such as the potassium competitive acid blockers and, among them the most studied vonoprazan, which are characterized by a better pharmacological profile than PPIs (rapid onset of action, longer lasting acid suppression, control of nocturnal acidity), has the potential to overcome the above-mentioned unmet needs. More research should be done to assess their efficacy in Western populations and their safety in patients treated in the long term.

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

Abstract
Eosinophilic esophagitis (EoE) is a chronic immune-mediated disorder characterised by eosinophilic inflammation and esophageal dysfunction symptoms. The recommended first-line treatment options are proton pump inhibitors and swallowed topical steroids (STS). However, current recommendations regarding STS are based on relatively few studies employing various doses and formulations. Our aim was to review the STS formulations currently used in the treatment of eosinophilic esophagitis, to demonstrate in a practical way the variety of exiting application methods, and to present emerging options for STS delivery to the esophagus. After the literature review, we established that the three most commonly used STS formulations include mist from an inhaler, viscous suspensions compounded with vehicles for oral use, and a recently introduced proprietary medication in the form of orodispersible tablets. Several drug delivery technologies with potential use in EoE are under investigation. To ensure optimal adherence, the choice of formulation should be based on efficacy, patient preferences and experience of the clinician, as well as current recommendations. Further studies are needed to compare the efficacy and acceptability of existing STS types, and to develop new, well-tolerated and effective drug formulations.

Abstract
Eosinophilic esophagitis (EoE) is an antigen-mediated chronic T helper type 2 (Th2)-associated inflammatory disorder that has emerged in the last three decades as an increasingly common cause of esophageal symptoms. Despite rising incidence and prevalence, there are currently no approved therapies for EoE in the United States and only one oral topical corticosteroid approved in Europe and Canada. Current management relies on labor- and endoscopy-intensive dietary elimination, proton-pump inhibitors (PPIs) with only moderate efficacy, and use of inhaled or nebulized topical corticosteroids designed for asthma and limited by accessibility. Fortunately, progress in elucidating the underlying pathophysiology of EoE has led to the development of new therapies derived from molecular targets necessary for disease pathogenesis. We summarize established and emerging medical therapies for EoE, with a focus on new treatments with specific molecular targets that are likely to change EoE management paradigms in the next decade.

Abstract
BACKGROUND The growing prevalence of eosinophilic esophagitis (EoE) represents a considerable burden to patients and health care systems. Optimizing cost-effective management and identifying mechanisms for disease onset and progression are required. However, the paucity of large patient cohorts and heterogeneity of practice hinder the defining of optimal management of EoE. METHODS EoE CONNECT is an ongoing, prospective registry study initiated in 2016 and currently managed by EUREOS, the European Consortium for Eosinophilic Diseases of the Gastrointestinal Tract. Patients are managed and treated by their responsible specialists independently. Data recorded using a web-based system include demographic and clinical variables; patient allergies; environmental, intrapartum, and early life exposures; and family background. Symptoms are structurally assessed at every visit; endoscopic features and histological findings are recorded for each examination. Prospective treatment data are registered sequentially, with new sequences created each time a different treatment (active principle, formulation, or dose) is administered to a patient. EoE CONNECT database is actively monitored to ensure the highest data accuracy and the highest scientific and ethical standards. RESULTS EoE CONNECT is currently being conducted at 39 centers in Europe and enrolls patients of all ages with EoE. In its aim to increase knowledge, to date EoE CONNECT has provided evidence on the effectiveness of first- and second-line therapies for EoE in clinical practice, the ability of proton pump inhibitors to induce disease remission, and factors associated with improved response. Drug effects to reverse fibrous remodeling and endoscopic features of fibrosis in EoE have also been assessed. CONCLUSION This prospective registry study will provide important information on the epidemiological and clinical aspects of EoE and evidence as to the real-world and long-term effectiveness and safety of therapy. These data will potentially be a vital benchmark for planning future EoE health care services in Europe.

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

Abstract
Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder characterized by symptoms of esophageal dysfunction and eosinophil-predominant inflammation. Left untreated, EoE progresses to fibrous remodeling and stricture formation that impairs quality of life. Therefore, EoE requires either repeated treatments or maintenance therapy. Current guidelines recommend swallowed topical corticosteroids (STCs), proton-pump inhibitors (PPIs), or dietary intervention as initial options to induce and maintain long-term disease remission. Impractical exclusive elemental diets and suboptimal allergy testing-directed food avoidance paved the way for empirical elimination diets. These are moderately effective and highly reproducible in inducing EoE remission and allow for identification of specific food triggers. Step-up strategies, including two- and four-food rather than six-food elimination diets, should be considered as initial approaches for dietary treatment in patients of all ages, as they reduce the need for endoscopic procedures, shorten diagnostic processing time, and avoid unnecessary restrictions. Formulations of STC originally designed for asthma therapy are suboptimal for EoE treatment, with new effervescent orodispersible tablets and viscose formulations designed to coat the esophageal mucosa providing increased effectiveness at reduced doses. The anti-inflammatory effects of PPI in EoE are independent from gastric acid secretion inhibition; despite evidence from observational research, PPIs are the most commonly prescribed first-line therapy for EoE due to their accessibility, low cost, and safety profile. Double doses of PPI only induce remission in half of EoE patients, irrespective of the drug used or patients' age. Inflammatory rather than stricturing EoE phenotype and treatment duration up to 12 weeks increase chances of achieving EoE remission. Most responders effectively maintain long-term remission with standard PPI doses. Finally, endoscopic dilation should be considered in patients with reduced esophageal caliber or persistent dysphagia despite histological remission. This article provides a state-of-the-art review and updated discussion of current therapies and newly developed options for EoE.

Abstract
Eosinophilic esophagitis (EoE) is a chronic immune-mediated disease of the esophagus characterized clinically by symptoms related to esophageal dysfunction and histologically by eosinophil-predominant inflammation, whose incidence is rising. It significantly affects patients’ quality of life and, if left untreated, results in fibrotic complications. Although broad consensus has been achieved on first-line therapy, a subset of patients remains non-responder to standard therapy. The pathogenesis of EoE is multifactorial and results from the complex, still mostly undefined, interaction between genetics and intrinsic factors, environment, and antigenic stimuli. A deep understanding of the pathophysiology of this disease is pivotal for the development of new therapies. This review provides a comprehensive description of the pathophysiology of EoE, starting from major pathogenic mechanisms (genetics, type 2 inflammation, epithelial barrier dysfunction, gastroesophageal reflux, allergens, infections and microbiota) and subsequently focusing on the single protagonists of type 2 inflammation (involved cells, cytokines, soluble effectors, surface proteins and transcription factors) that could represent present and future therapeutic targets, while summarizing previous therapeutic approaches in literature.

Abstract
BACKGROUND Long-standing inflammation leads to esophageal remodeling with stricture formation in patients with eosinophilic esophagitis (EoE). The ability of proton pump inhibitors (PPI) to reverse endoscopic features of fibrosis is still unknown. OBJECTIVE To investigate the effect of a short course of PPI treatment in reducing endoscopic findings indicative of esophageal fibrosis in EoE patients. METHODS Cross-sectional analysis of the EoE CONNECT registry. Patients who received PPI to induce EoE remission were evaluated. Endoscopic features were graded using the EoE Endoscopic Reference Score (EREFS), with rings and strictures indicating fibrosis. Results were compared to those from patients treated with swallowed topic corticosteroids (STC). RESULTS Clinico-histological remission was achieved in 83/166 adult patients treated with PPI (50%) and in 65/79 (82%) treated with STC; among responders, 60 (36%) and 57 (72%) patients respectively achieved deep histological remission (<5 eosinophils/hpf). At baseline, mean±SD EREFS was lower in patients treated with PPI compared to those who received STC (p < 0.001). Short term treatment significantly reduced EREFS scores in patients treated either with PPI or STC as well as rings and strictures. Among patients treated with PPI, deep histological remission (<5 eosinophils/hpf) provided further reduction in total EREFS score. CONCLUSION Effective PPI therapy for EoE significantly reduced endoscopic esophageal fibrosis in the short term.

Abstract
Background Proton pump inhibitors (PPIs) are often the first drug of choice in the treatment of eosinophilic oesophagitis (EoE), and in Denmark 8 weeks of high‐dose PPI therapy is recommended as first‐line treatment followed by rebiopsying, reflecting international recommendations. Aims To assess the population‐based effectiveness of PPIs in the treatment of EoE and evaluate whether patients were treated and followed according to the regional guideline. Methods This is a retrospective, registry‐based, DanEoE cohort study of 236 adult EoE patients diagnosed between 2007 and 2017 in the North Denmark Region. After patient file revision, the EoE diagnosis was defined according to the AGREE 2 consensus. Symptomatic PPI response was defined as complete symptom resolution and histological remission (<15 eosinophils per high‐power field). Results PPI treatment was initiated in 92% of the EoE patients. High‐ and low‐dose PPIs were prescribed in 55% and 45% of the cases, respectively. When treated with high‐dose PPIs, 68% of the patients were completely symptom‐free, and 49% were in histological remission. In 39% of high‐dose PPI‐treated patients, the symptomatic and histological responses were conflicting. While treated with PPIs, complications were rare, with <5% strictures in responders and <10% in non‐responders. Rebiopsying was done in 67% of the EoE patients started on PPIs. Conclusions High‐dose PPI treatment was effective in half of the EoE patients started on PPIs, but conflicting symptomatic and histological PPI responses were common. Complications were rare when PPIs were started. One‐third of the patients were not rebiopsied as recommended.

Abstract
Despite dramatic advances in our understanding of the pathogenesis and course of disease in the relatively short timeframe since the discovery and first description of eosinophilic esophagitis (EoE) less than three decades ago, many open questions remain to be elucidated. For instance, we will need to better characterize atypical clinical presentations of EoE and other forms of esophageal inflammatory conditions with often similar clinical presentations, nut fulfilling current diagnostic criteria for EoE and to determine their significance and interrelationship with genuine EoE. In addition, the interrelationship of EoE with other immune-mediated diseases remains to be clarified. Hopefully, a closer look at the role of environmental factors and their interaction with genetic susceptibility often in context of atopic predisposition may enable identifying the candidate substances/agents/allergens and potentially earlier (childhood) events to trigger the condition. It appears plausible to assume that in the end—comparable to current concepts in other immune-mediated chronic diseases, such as for instance inflammatory bowel disease or asthma bronchiale—we will not be rewarded with the identification of a “one-and-only” underlying pathogenetic trigger factor, with causal responsibility for the disease in each and every EoE patient. Rather, the relative contribution and importance of intrinsic susceptibility, i.e., patient-driven factors (genetics, aberrant immune response) and external trigger factors, such as food (or aero-) allergens as well as early childhood events (e.g., infection and exposure to antibiotics and other drugs) may substantially differ among given individuals with EoE. Accordingly, selection and treatment duration of medical therapy, success rates and extent of required restriction in dietary treatment, and the need for mechanical treatment to address strictures and stenosis require an individualized approach, tailored to each patient. With the advances of emerging treatment options, the importance of such an individualized and patient-centered assessment will increase even further.

Abstract
BACKGROUND Proton pump inhibitors (PPIs) are effective therapies for eosinophilic oesophagitis (EoE), but the mechanism of action is uncertain. At on-PPI impedance-pH monitoring, improvement in oesophageal chemical clearance assessed with post-reflux swallow-induced peristaltic wave (PSPW) index characterises PPI-responsive EoE and reflux disease. Off-PPI, higher efficacy of the oesophago-salivary reflex as measured with PSPW-associated pH increments characterises PPI-responsive reflux disease and could typify PPI-responsive EoE as well. AIM To establish whether PPI responsiveness in EoE is associated with higher efficacy of the oesophago-salivary reflex. METHODS Prospective multicentre study in EoE patients investigated with impedance-pH monitoring before starting PPI. Impedance-pH parameters in PPI-responsive and PPI-refractory cases were compared. PPI response was defined histologically. RESULTS Considerable PSPW-associated pH increments (median 1.4 units) were found in 80 EoE patients, with significantly higher values in 48 PPI-responsive than in 32 PPI-refractory cases (1.8 vs 1.0, P = 0.02). Mucosal integrity, as measured with mean nocturnal baseline impedance was more severely impaired in the distal oesophagus in PPI-responsive cases, the gradient between mid and distal oesophagus being significantly higher (546 vs 137 Ω, P = 0.0002). PSPW-associated pH increments and the baseline impedance gradient between mid and distal oesophagus were independently associated with histological response at multivariable logistic regression; at receiver operating characteristic analysis, the area under the curve of PPI response calculated by combined assessment was 0.88. CONCLUSION Higher efficacy of oesophago-salivary reflex and more severe mucosal damage in the distal oesophagus are associated with EoE response to PPIs, implying an anti-reflux mechanism of action as most likely.

Abstract
Eosinophilic esophagitis (EoE) is a unique form of non-immunoglobulin E-mediated food allergy, restricted to the esophagus, characterized by esophageal eosinophil-predominant inflammation and dysfunction. The diagnosis requires an esophago-gastroduodenoscopy with esophageal biopsies demonstrating active eosinophilic inflammation with 15 or more eosinophils/high-power field, following the exclusion of alternative causes of eosinophilia. Food allergens trigger the disease, withdairy/milk, wheat/gluten, egg, soy/legumes, and seafood the most common. Therapeutic strategies comprise dietary restrictions, proton pump inhibitors, topical corticosteroids, biologic agents, and esophageal dilation when strictures are present. However, avoidance of trigger foods remains the only option targeting the cause, and not the effect, of the disease. Because EoE relapses when treatment is withdrawn, dietary therapy offers a long-term, drug-free alternative to patients who wish to remain off drugs and still be in remission. There are currently multiple dietary management strategies to choose from, each having its specific efficacy, advantages, and disadvantages that both clinicians and patients should acknowledge. In addition, dietary regimens should be tailored around each individual patient to increase the chance of tolerability and long-term adherence. In general, liquid elemental diets devoid of antigens and elimination diets restricting causative foods are valuable options. Designing diets on the basis of food allergy skin tests results is not reliable and should be avoided. This review summarizes the most recent knowledge regarding the clinical use of dietary measures in EoE. We discussed endpoints, rationale, advantages and disadvantages, and tailoring of diets, as well as currently available dietary regimens for EoE.

Abstract
BACKGROUND & AIMS In upper airway cells, T helper 2 cytokines that signal through interleukin-4 (IL-4) receptor-α have been shown to stimulate eotaxin-3 secretion via a nongastric proton pump (ngH+,K+ATPase). To seek novel targets for eosinophilic esophagitis (EoE) treatments, we evaluated ngH+,K+ATPase expression in EoE squamous cells, and explored molecular pathways involved in eotaxin-3 secretion by IL-4 receptor-α signaling. METHODS ngH+,K+ATPase expression in EoE cells was evaluated by quantitative real-time polymerase chain reaction and Western blotting. IL-4-stimulated eotaxin-3 secretion was measured by enzyme-linked immunosorbent assay after treatment with omeprazole, SCH 28080 (potassium-competitive acid blocker), ethylene glycol-bis(β-aminoethyl)-N,N,N',N'-tetraacetoxymethyl ester (calcium chelator), 2-aminoethoxydiphenyl borate (inhibitor of endoplasmic reticulum calcium release), verapamil, and diltiazem (L-type calcium channel inhibitors). Intracellular calcium transients were measured by Fluo-4 fluorescence. Key experiments were confirmed in EoE primary cells and in RNA sequencing datasets from mucosal biopsies of patients with EoE and controls. RESULTS EoE cells expressed ngH+,K+ATPase messenger RNA and protein. Omeprazole and SCH 28080 decreased IL-4-stimulated eotaxin-3 secretion. IL-4 increased intracellular calcium transients, and IL-4-stimulated eotaxin-3 secretion was blocked by ethylene glycol-bis(β-aminoethyl)-N,N,N',N'-tetraacetoxymethyl ester, 2-aminoethoxydiphenyl borate, verapamil, and diltiazem. The combination of omeprazole and verapamil suppressed IL-4-stimulated eotaxin-3 secretion more than either agent alone. EoE biopsies expressed higher ngH+,K+ATPase and exhibited more calcium signaling than controls. CONCLUSIONS EoE cells express a nongastric proton pump that mediates T helper 2 cytokine-stimulated eotaxin-3 secretion. IL-4 induces calcium release from the endoplasmic reticulum and calcium entry via L-type calcium channels, increasing intracellular calcium that contributes to eotaxin-3 secretion by EoE cells. L-type calcium channel inhibitors block T helper 2 cytokine-stimulated eotaxin-3 secretion, suggesting a potential role for these agents in EoE treatment.

Eosinophilic esophagitis: clinical, endoscopic, histologic and therapeutic differences and similarities between children and adults. Therap Adv Gastroenterol 2021; 14:1756284820980860. [PMID: 33613690 PMCID: PMC7871287 DOI: 10.1177/1756284820980860] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Accepted: 11/20/2020] [Indexed: 02/04/2023] Open
Abstract
In the absence of secondary causes, eosinophilic esophagitis (EoE) is a chronic, local, progressive, T-helper type 2 immune-mediated disorder characterized by symptoms of esophageal dysfunction and eosinophil-predominant inflammation. In the last 20 years, the incidence and prevalence of EoE have risen sharply, and the chances of encountering affected patients in clinics and endoscopy rooms have increased. Nevertheless, it is estimated that the mean diagnostic delay of EoE is 4-6 years in both children and adults. Unfortunately, the longer the disease stays unrecognized, the likelier it is for the patient to have persistent or increased esophageal eosinophilic inflammation, to complain of non-resolving symptoms, and to develop fibrotic complications. Early detection depends on the recognition of initial clinical manifestations that vary from childhood to adulthood and even among patients of the same age. The disease phenotype also influences therapeutic approaches that include drugs, dietary interventions, and esophageal dilation. We have herein reviewed epidemiologic, clinical, endoscopic, and histologic features and therapeutic options of EoE focusing on differences and similarities between children and adults that may certainly serve in daily clinical practice.

Practice Patterns for Eosinophilic Esophagitis Patients in Busan and Gyeongnam: A Korean Multicenter Database Study. J Neurogastroenterol Motil 2021; 27:71-77. [PMID: 32699187 PMCID: PMC7786091 DOI: 10.5056/jnm20069] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 05/19/2020] [Accepted: 06/08/2020] [Indexed: 12/21/2022] Open
Abstract
Background/Aims The prevalence of eosinophilic esophagitis is increasing in Korea and there are few single-center studies regarding eosinophilic esophagitis in Korea. In particular, data about management for eosinophilic esophagitis are lacking. We aim to evaluate the practice patterns, including initial treatment and response, in the Busan city and Gyeongnam province area. Methods We retrospectively reviewed medical records to gain data on patient characteristics, medication, endoscopic images, and esophageal biopsy results. From January 2009 to December 2019, a total of 42 patients were diagnosed with eosinophilic esophagitis. Results The mean age was 50.7 (from 22 to 81) years and the cohort was predominantly male (78.6%, 33/42). The proton pump inhibitor was the preferred treatment as an initial trial for 64.3% (27/42) of patients, followed by swallowed topical steroids (16.7%, 7/42). Clinical improvement after proton pump inhibitor therapy was achieved in 88.9% (24/27) of patients. Two patients who did not achieve improvement showed a clinical and endoscopic response after swallowed topical steroids treatment. No patient received diet elimination or balloon dilatation therapy. Conclusions The treatment response of eosinophilic esophagitis was good in Busan city and Gyeongnam province area in Korea. Proton pump inhibitor therapy was the preferred and most effective treatment for eosinophilic esophagitis as the initial therapy.

Abstract
INTRODUCTION The rapid expansion in the epidemiology of eosinophilic esophagitis (EoE) is being documented, along with cumulative research assessing environmental exposures associated with EoE and susceptibility due to genetic variants. AREAS COVERED Incidence rates for EoE of 5-10 new cases per 100,000 inhabitants annually have shown an increase in recent reports of up to 20 in some countries; the highest prevalence being reported for Europe and North America, where EoE now affects more than 1 out of 1,000 people. EoE has been shown to be associated with several disorders, Th2-mediated atopies being the most common. Patients with EoE exhibit increased frequency of asthma, allergic rhinitis and eczema, and EoE has been considered as a late component of the atopic march. Risk variants in TSLP, CAPN14 and LRCC32 genes, among others, have all been related to EoE, and interact with prenatal and early life exposure potentially modifying abundance and composition of gut microbiome. Dysregulated interactions between bacteria and mucosal immunity emerge as leading causes of EoE. EXPERT OPINION The expanding epidemiology of EoE, the resources needed and subsequent increasing healthcare costs require additional effort to optimize cost-effective management and unveil mechanisms that enhance the development of future preventive strategies.

Abstract
INTRODUCTION Eosinophilic Esophagitis (EoE) is an immune-mediated, chronic inflammatory disorder of the esophagus. Topical steroids have been used in the management of EoE for over 15 years. However, there are no Food and Drug Administration (FDA) approved drug therapies for EoE. AREAS COVERED This review discusses the current understanding of EoE and the role of topical steroids in the induction and maintenance of remission in patients with EoE. We performed a comprehensive review of the literature, summarized randomized control trials from 2006 to 2020, and provided a simplified management algorithm for EoE. EXPERT OPINION In patients with EoE, topical steroids are effective in inducing clinical and histologic remission. Formulations of topical steroids that maximize the exposure to esophageal mucosa have the highest efficacy. A majority of patients who achieve remission with topical steroids develop clinical and histologic relapse off therapy within a year. Current evidence suggests that maintenance therapy with long-term topical steroids decreases the risk of relapse and progression to fibrostenotic disease. While uncertainty over the dose and duration of maintenance topical steroids and their potential side effects exists, long-term maintenance therapy with topical steroids appears to be the way forward to improve long-term outcomes in patients with EoE.
