Abstract
BACKGROUND & AIMS Esophageal dilation improves dysphagia but not inflammation in eosinophilic esophagitis (EoE) patients. We investigated if dilation modifies the association between symptoms and peak esophageal eosinophils per high-power field (eos/hpf). METHODS Adults enrolled in a multisite prospective Consortium of Gastrointestinal Eosinophilic Disease Researchers Outcome Measures for Eosinophilic Gastrointestinal Diseases Across Ages observational study (NCT02523118) completed the symptom-based EoE activity index (EEsAI) patient-reported outcome instrument and underwent endoscopy with biopsy specimens. Patients were stratified based on dilation status as absent, performed 1 year or less before endoscopy, and performed more than 1 year before endoscopy. Assessments included Spearman correlations of the relationship between symptoms and eos/hpf and linear regression with EEsAI as the outcome, eos/hpf as predictor, and interaction for dilation and eos/hpf. RESULTS Among 100 patients (n = 61 males; median age, 37 y), 15 and 40 patients underwent dilation 1 year or less and more than 1 year before index endoscopy, respectively. In nondilated patients, the association between eos/hpf and symptoms was moderate (ρ = 0.49; P < .001); for a 10-eos/hpf increase, the predicted EEsAI increased by 2.69 (P = .002). In patients dilated 1 or less and more than 1 year before index endoscopy, this association was abolished (ρ = -0.38; P = .157 for ≤1 y and ρ = 0.02; P = .883 >1 y); for a 10-eos/hpf increase, the predicted EEsAI changed by -1.64 (P = .183) and 0.78 (P = .494), respectively. Dilation modified the association between symptoms and eos/hpf (P = .005 and P = .187 for interaction terms of eos/hpf and dilation 1 or less years before and more than 1 year before index endoscopy, respectively). CONCLUSIONS In nondilated EoE adults, eos/hpf correlate modestly with symptoms; this correlation was no longer appreciated in dilated patients, and the dilation effects lasted longer than 1 year. Dilation status should be considered in studies evaluating EoE treatment and for clinical follow-up evaluation.

Abstract
BACKGROUND & AIMS Eosinophilic esophagitis (EoE) can progress to fibrostenosis by unclear mechanisms. Herein, we investigated gene dysregulation in fibrostenotic EoE, its association with clinical parameters and specific pathways, and the functional consequences. METHODS Esophageal biopsies from subjects with EoE were collected across 11 Consortium of Eosinophilic Gastrointestinal Disease Researchers sites (n = 311) and 2 independent replication cohorts (n = 83). Inclusion criteria for fibrostenotic EoE were endoscopic rings, stricture, and/or a history of dilation. Endoscopic, histologic, and molecular features were assessed by the EoE Endoscopic Reference Score, EoE Histology Scoring System, EoE Diagnostic Panel, and RNA sequencing. Esophageal endothelial TSPAN12 expression and functional effects on barrier integrity and gene expression were analyzed in vitro. RESULTS TSPAN12 was the gene most correlated with fibrostenosis (r = -0.40, P < .001). TSPAN12 was lower in fibrostenotic EoE and correlated with EoE Endoscopic Reference Score, EoE Diagnostic Panel, and EoE Histology Scoring System (r = 0.34-0.47, P < .001). Lower TSPAN12 associated with smaller esophageal diameter (r = 0.44, P = .03), increased lamina propria fibrosis (r = -0.41, P < .001), and genes enriched in cell cycle-related pathways. Interleukin (IL)-13 reduced TSPAN12 expression in endothelial cells. Conversely, anti-IL-13 therapy increased TSPAN12 expression. TSPAN12 gene silencing increased endothelial cell permeability and dysregulated genes associated with extracellular matrix pathways. Endothelial cell-fibroblast crosstalk induced extracellular matrix changes relevant to esophageal remodeling. CONCLUSIONS Patients with fibrostenotic EoE express decreased levels of endothelial TSPAN12. We propose that IL-13 decreases TSPAN12, likely contributing to the chronicity of EoE by promoting tissue remodeling through fibroblast-endothelial cell crosstalk.

Abstract
BACKGROUND End points used to determine treatment efficacy in eosinophilic esophagitis (EoE) have evolved over time. With multiple novel therapies in development for EoE, harmonization of outcomes measures will facilitate evidence synthesis and appraisal when comparing different treatments. OBJECTIVE We sought to develop a core outcome set (COS) for controlled and observational studies of pharmacologic and diet interventions in adult and pediatric patients with EoE. METHODS Candidate outcomes were generated from systematic literature reviews and patient engagement interviews and surveys. Consensus was established using an iterative Delphi process, with items voted on using a 9-point Likert scale and with feedback from other participants to allow score refinement. Consensus meetings were held to ratify the outcome domains of importance and the core outcome measures. Stakeholders were recruited internationally and included adult and pediatric gastroenterologists, allergists, dieticians, pathologists, psychologists, researchers, and methodologists. RESULTS The COS consists of 4 outcome domains for controlled and observational studies: histopathology, endoscopy, patient-reported symptoms, and EoE-specific quality of life. A total of 69 stakeholders (response rate 95.8%) prioritized 42 outcomes in a 2-round Delphi process, and the final ratification meeting generated consensus on 33 outcome measures. These included measurement of the peak eosinophil count, Eosinophilic Esophagitis Histology Scoring System, Eosinophilic Esophagitis Endoscopic Reference Score, and patient-reported measures of dysphagia and quality of life. CONCLUSIONS This interdisciplinary collaboration involving global stakeholders has produced a COS that can be applied to adult and pediatric studies of pharmacologic and diet therapies for EoE and will facilitate meaningful treatment comparisons and improve the quality of data synthesis.
