AbstractBackgroundPost‐infectious disorders of gut‐brain interaction (PI‐DGBI) have significant impact on children and adolescents. The effect of COVID‐19 on PI‐DGBI‐associated symptoms in this population, however, is unknown.MethodsWe performed electronic medical record searches to identify patients 8–17 years old with a SARS‐CoV2 PCR test at Lurie Children's Hospital between November 2020 and March 2021 (cohort 1) and April–October 2021 (cohort 2). Questionnaires were administered to assess symptoms prior to and 3 months following the test. This included the Pediatric Eosinophilic Esophagitis Symptom Score (PEESS), questionnaire of pediatric gastrointestinal symptoms—Rome IV, Nausea Profile (NP), dyspepsia symptom survey (DSS), nausea severity profile (NSP), and Pediatric Quality of Life Inventory (PedsQL). We grouped patients based on the presence of symptoms prior to COVID‐19 test or the test result.ResultsOne hundred and ninety‐six parent(s) or guardian(s) in cohort 1 and 274 in cohort 2 completed surveys and self‐reported their child's COVID‐19 result. Cohort 1 had increased PEESS and DSS scores, lower PedsQL scores, and increased frequency of abdominal pain disorders among patients with symptoms prior to COVID‐19 testing. Both cohorts had increased NP and NSP scores among patients with symptoms prior to COVID‐19 testing that was highest among patients with a positive COVID‐19 test. Abdominal pain and diarrhea prior to COVID‐19 testing predicted higher NP scores.ConclusionsAmong symptomatic COVID‐19 tested children, we found increased severity of nausea‐associated somatic, emotional, and gastrointestinal symptoms in the 3 months following the test that was most increased among patients with a positive COVID‐19 test.

In response to the social inequities that exist in health care, the NIH-funded Consortium of Eosinophilic Gastrointestinal Disease Researchers (CEGIR) recently formed a diversity committee to examine systemic racism and implicit bias in the care and research of eosinophilic gastrointestinal diseases (EGIDs). Herein, we describe our process, highlighting milestones and issues addressed since the committee’s inception, which we hope will inspire other researchers to enhance diversity, equity, inclusion, and accessibility (DEIA) in their fields. Our journey began by establishing mission and vision statements to define the purpose of the committee. Regular discussion of diversity-related topics was incorporated into existing meetings and web-based materials were shared. This was followed by educational initiatives, including establishing a library of relevant publications and a speaker series to address DEIA topics. We then established a research agenda focused on the following actionable items: (1) to define what is known about the demographics of EGIDs by systematic review of population-based studies; (2) to develop a practical tool for reporting participant demographics to reduce bias in EGID literature; (3) to examine health disparities in the care of individuals with eosinophilic esophagitis who present to the emergency department with an esophageal food impaction; (4) to examine how access to a gastroenterologist affects the conclusions of published research examining the prevalence of pediatric eosinophilic esophagitis; and (5) to develop a model for examining the dimensions of diversity, and provide a framework for CEGIR’s ongoing projects and data capture. In addition to promoting consciousness of DEIA, this initiative has fostered inclusivity among CEGIR members and will continue to inspire positive changes in EGID care and research.

OBJECTIVES: Eosinophilic esophagitis (EoE), a chronic food allergic disease, lacks sensitive and specific peripheral biomarkers. We hypothesized that levels of EoE-related biomarkers captured using a 1-hour minimally invasive Esophageal String Test (EST) would correlate with mucosal eosinophil counts and tissue concentrations of these same biomarkers. We aimed to determine whether a 1-hour EST accurately distinguishes active from inactive EoE or a normal esophagus. METHODS: In a prospective, multisite study, children and adults (ages 7–55 years) undergoing a clinically indicated esophagogastroduodenoscopy performed an EST with an esophageal dwell time of 1 hour. Subjects were divided into 3 groups: active EoE, inactive EoE, and normal esophageal mucosa. Eosinophil-associated protein levels were compared between EST effluents and esophageal biopsy extracts. Statistical modeling was performed to select biomarkers that best correlated with and predicted eosinophilic inflammation. RESULTS: One hundred thirty-four subjects (74 children, 60 adults) with active EoE (n = 62), inactive EoE (n = 37), and patient controls with a normal esophagus (n = 35) completed the study. EST-captured eosinophil-associated biomarkers correlated significantly with peak eosinophils/high-power field, endoscopic visual scoring, and the same proteins extracted from mucosal biopsies. Statistical modeling, using combined eotaxin-3 and major basic protein-1 concentrations, led to the development of EoE scores that distinguished subjects with active EoE from inactive EoE or normal esophagi. Eighty-seven percent of children, 95% of parents, and 92% of adults preferred the EST over endoscopy if it provided similar information. DISCUSSION: The 1-hour EST accurately distinguishes active from inactive EoE in children and adults and may facilitate monitoring of disease activity in a safe and minimally invasive fashion.
