    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.

    Gastrointestinal Eosinophilic Granulomatosis with Polyangiitis following a Clostridium difficile Infecti
    (Karger, 2023-06-13) Mohideen, Haseeb; Weldemichael, Wegahta; Hussain, Hafsa; Dahiya, Dushyant Singh; Shin, Andrea; Medicine, School of Medicine
    Eosinophilic granulomatosis with polyangiitis (EGPA), historically named Churg-Strauss syndrome, is a rare vasculitis affecting small- and medium-sized blood vessels. The disease has a predilection for numerous organs including the lungs, sinuses, kidneys, heart, nerves, and gastrointestinal tract but is prominently associated with asthma, rhinosinusitis, and eosinophilia. Gastrointestinal involvement is common; however, a gastrointestinal manifestation as the cardinal symptom following an infection is atypical. Here, we present a case of a 61-year-old male who presented with persistent diarrhea following a toxigenic Clostridium difficile infection despite multiple antibiotic courses. Repeat testing confirmed eradication of the infection, and further evaluation with colon biopsy revealed small and medium-sized vasculitis with eosinophilic infiltration and granulomas. Treatment with prednisone and cyclophosphamide resulted in rapid improvement of his diarrhea. Gastrointestinal symptoms in EGPA are associated with worse prognosis, so prompt identification and treatment of the disease is crucial. EGPA is rarely documented in histopathological samples from the gastrointestinal tract as endoscopic biopsies are typically too superficial to sample the submucosal layer containing the affected vessels. Additionally, the link between EGPA and infections as a potential trigger has not been clearly established, but gastrointestinal EGPA manifesting after a colonic infection raises concerns that this may have been a triggering event. Ultimately, further study is needed to understand, diagnose, and treat gastrointestinal and postinfection EGPA.

    Impressions and aspirations from the FDA GREAT VI Workshop on Eosinophilic Gastrointestinal Disorders Beyond Eosinophilic Esophagitis and Perspectives for Progress in the Field
    (Elsevier, 2022) Rothenberg, Marc E.; Hottinger, Shawna K. B.; Gonsalves, Nirmala; Furuta, Glenn T.; Collins, Margaret H.; Talley, Nicholas J.; Peterson, Kathryn; Menard-Katcher, Calies; Smith, Macie; Hirano, Ikuo; Genta, Robert M.; Chehade, Mirna; Gupta, Sandeep K.; Spergel, Jonathan M.; Aceves, Seema S.; Dellon, Evan S.; Pediatrics, School of Medicine
    The US Food and Drug Administration hosted a workshop on July 21, 2021, to discuss the disease characteristics, natural history, and end points to assess treatment benefit in patients with eosinophilic gastrointestinal disorders (EGIDs) beyond eosinophilic esophagitis (EoE). Notably, EGIDs beyond EoE, such as eosinophilic gastritis, eosinophilic enteritis, and eosinophilic colitis, herein referred to as non-EoE EGIDs, are understudied relative to EoE. This workshop provided a forum for open discussion among stakeholders-medical professionals (including their societies and research groups), Food and Drug Administration representatives, an industry representative, and a patient representative-to facilitate drug development. Experts in many disciplines related to EGIDs, including allergy, immunology, epidemiology, gastroenterology, and pathology, and both adult and pediatric clinicians contributed. Herein, we discuss some of the insights of the material presented at the meeting and present perspectives on moving the field forward toward drug approval.

    Prospective Endoscopic Activity Assessment for Eosinophilic Gastritis in a Multisite Cohort
    (Wolters Kluwer, 2022) Hirano, Ikuo; Collins, Margaret H.; King, Eileen; Sun, Qin; Chehade, Mirna; Abonia, J. Pablo; Bonis, Peter A.; Capocelli, Kelly E.; Dellon, Evan S.; Falk, Gary W.; Gonsalves, Nirmala; Gupta, Sandeep K.; Leung, John; Katzka, David; Menard-Katcher, Paul; Khoury, Paneez; Klion, Amy; Mukkada, Vincent A.; Peterson, Kathryn; Shoda, Tetsuo; Rudman-Spergel, Amanda K.; Spergel, Jonathan A.; Yang, Guang-Yu; Rothenberg, Marc E.; Aceves, Seema S.; Furuta, Glenn T.; CEGIR investigators; Pediatrics, School of Medicine
    Introduction: Eosinophilic gastritis (EG) is a chronic inflammatory disease of the stomach characterized by eosinophil-predominant gastric mucosal inflammation and gastrointestinal symptoms. The aim of this study was to prospectively evaluate endoscopic features in a large series of children and adults with EG to better understand the endoscopic manifestations and develop a standardized instrument for investigations. Methods: Data were prospectively collected as part of the Consortium for Eosinophilic Gastrointestinal Disease Researchers, a national collaborative network. Endoscopic features were prospectively recorded using a system specifically developed for EG, the EG Endoscopic Reference System (EG-REFS). Correlations were made between EG-REFS and clinical and histologic features. Results: Of 98 patients with EG, 65 underwent assessments using EG-REFS. The most common findings were erythema (72%), raised lesions (49%), erosions (46%), and granularity (35%); only 8% of patients with active histology (≥30 eosinophils/high-power field) exhibited no endoscopic findings. A strong correlation between EG-REFS scores and physician global assessment of endoscopy severity was demonstrated (Spearman r = 0.84, P < 0.0001). The overall score and specific components of EG-REFS were more common in the antrum than in the fundus or body. EG-REFS severity was significantly correlated with active histology, defined by a threshold of ≥30 eosinophils/high-power field (P = 0.0002). Discussion: Prospective application of EG-REFS identified gastric features with a strong correlation with physician global assessment of endoscopic activity in EG. Endoscopic features demonstrated greater severity in patients with active histology and a predilection for the gastric antrum. Further development of EG-REFS should improve its utility in clinical studies.
