    Background & aims: Disease activity and severity of eosinophilic esophagitis (EoE) dictate therapeutic options and management, but the decision-making process for determining severity varies among practitioners. To reduce variability in practice patterns and help clinicians monitor the clinical course of the disease in an office setting, we aimed to create an international consensus severity scoring index for EoE. Methods: A multidisciplinary international group of adult and pediatric EoE researchers and clinicians, as well as non-EoE allergy immunology and gastroenterology experts, formed 3 teams to review the existing literature on histology, endoscopy, and symptoms of EoE in the context of progression and severity. A steering committee convened a 1-day virtual meeting to reach consensus on each team's opinion on salient features of severity across key clinicopathologic domains and distill features that would allow providers to categorize disease severity. Results: Symptom features and complications and inflammatory and fibrostenotic features on both endoscopic and histologic examination were collated into a simplified scoring system-the Index of Severity for Eosinophilic Esophagitis (I-SEE)-that can be completed at routine clinic visits to assess disease severity using a point scale of 0-6 for mild, 7-14 for moderate, and ≥15 for severe EoE. Conclusions: A multidisciplinary team of experts iteratively created a clinically usable EoE severity scoring system denominated "I-SEE" to guide practitioners in EoE management by standardizing disease components reflecting disease severity beyond eosinophil counts. I-SEE should be validated and refined using data from future clinical trials and routine clinical practice to increase its utilization and functionality.

    Challenging assumptions about the demographics of eosinophilic gastrointestinal diseases: A systematic review
    (Elsevier, 2024-04-16) Chehade, Mirna; Wright, Benjamin L.; Walsh, Samantha; Bailey, Dominique D.; Muir, Amanda B.; Klion, Amy D.; Collins, Margaret H.; Davis, Carla M.; Furuta, Glenn T.; Gupta, Sandeep; Khoury, Paneez; Peterson, Kathryn A.; Jensen, Elizabeth T.; Pediatrics, School of Medicine
    Background: The demographic characteristics of patients with eosinophilic gastrointestinal diseases (EGIDs) are poorly understood. Population-based assessments of EGID demographics may indicate health disparities in diagnosis. Objectives: We aimed to characterize the demographic distribution of EGIDs and evaluate the potential for bias in reporting patient characteristics. Methods: We conducted a systematic review, extracting data on age, sex, gender, race, ethnicity, body mass index, insurance, and urban/rural residence on EGID patients and the source population. Differences in proportions were assessed by chi-square tests. Demographic reporting was compared to recent guidelines. Results: Among 50 studies that met inclusion/exclusion criteria, 12 reported ≥1 demographic feature in both EGID and source populations. Except for age and sex or gender, demographics were rarely described (race = 4, ethnicity = 1, insurance = 1) or were not described (body mass index, urban/rural residence). A higher proportion of male subjects was observed for EoE or esophageal eosinophilia relative to the source population, but no difference in gender or sex distribution was observed for other EGIDs. "Sex" and "gender" were used interchangeably, and frequently only the male proportion was reported. Reporting of race and ethnicity was inconsistent with guidelines. Conclusion: Current data support a male predominance for EoE only. Evidence was insufficient to support enrichment of EGIDs in any particular racial, ethnic, or other demographic group. Population-based studies presenting demographics on both cases and source populations are needed. Implementation of guidelines for more inclusive reporting of demographic characteristics is crucial to prevent disparities in timely diagnosis and management of patients with EGIDs.

    Development of a Core Outcome Set for Therapeutic Studies in Eosinophilic Esophagitis (COREOS)
    (Elsevier, 2021) Ma, Christopher; Schoepfer, Alain M.; Dellon, Evan S.; Bredenoord, Albert J.; Chehade, Mirna; Collins, Margaret H.; Feagan, Brian G.; Furuta, Glenn T.; Gupta, Sandeep K.; Hirano, Ikuo; Jairath, Vipul; Katzka, David A.; Pai, Rish K.; Rothenberg, Marc E.; Straumann, Alex; Aceves, Seema S.; Alexander, Jeffrey A.; Arva, Nicoleta C.; Atkins, Dan; Biedermann, Luc; Blanchard, Carine; Cianferoni, Antonella; Ciriza de los Rios, Constanza; Clayton, Frederic; Davis, Carla M.; de Bortoli, Nicola; Dias, Jorge A.; Falk, Gary W.; Genta, Robert M.; Ghaffari, Gisoo; Gonsalves, Nirmala; Greuter, Thomas; Hopp, Russell; Hsu Blatman, Karen S.; Jensen, Elizabeth T.; Johnston, Doug; Kagalwalla, Amir F.; Larsson, Helen M.; Leung, John; Louis, Hubert; Masterson, Joanne C.; Menard-Katcher, Calies; Menard-Katcher, Paul A.; Moawad, Fouad J.; Muir, Amanda B.; Mukkada, Vincent A.; Penagini, Roberto; Pesek, Robert D.; Peterson, Kathryn; Putnam, Philip E.; Ravelli, Alberto; Savarino, Edoardo V.; Schlag, Christoph; Schreiner, Philipp; Simon, Dagmar; Smyrk, Thomas C.; Spergel, Jonathan M.; Taft, Tiffany H.; Terreehorst, Ingrid; Vanuytsel, Tim; Venter, Carina; Vieira, Mario C.; Vieth, Michael; Vlieg-Boerstra, Berber; von Arnim, Ulrike; Walker, Marjorie M.; Wechsler, Joshua B.; Woodland, Philip; Woosley, John T.; Yang, Guang-Yu; Zevit, Noam; Safroneeva, Ekaterina; Medicine, School of Medicine
    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.

    Background & Aims Substantial heterogeneity in terminology used for eosinophilic gastrointestinal diseases (EGID), particularly the catchall term “eosinophilic gastroenteritis”, limits clinical and research advances. We aimed to achieve an international consensus for standardized EGID nomenclature. Methods This consensus process utilized Delphi methodology. An initial naming framework was proposed and refined in iterative fashion, then assessed in a first round of Delphi voting. Results were discussed in two consensus meetings, the framework was updated, and re-assessed in a second Delphi vote, with a 70% threshold set for agreement. Results Of 91 experts participating, 85 (93%) completed the first and 82 (90%) completed the second Delphi surveys. Consensus was reached on all but two statements. “EGID” was the preferred umbrella term for disorders of GI tract eosinophilic inflammation in the absence of secondary causes (100% agreement). Involved GI tract segments will be named specifically and use an “Eo” abbreviation convention: eosinophilic gastritis (now abbreviated EoG), eosinophilic enteritis (EoN), and eosinophilic colitis (EoC). The term “eosinophilic gastroenteritis” is no longer preferred as the overall name (96% agreement). When >2 GI tract areas are involved, the name should reflect all of the involved areas. Conclusions This international process resulted in consensus for updated EGID nomenclature for both clinical and research use. EGID will be the umbrella term rather than “eosinophilic gastroenteritis”, and specific naming conventions by location of GI tract involvement are recommended. As more data are developed, this framework can be updated to reflect best practices and the underlying science.
