INTRODUCTION: Treatment of celiac disease (CeD) requires a strict gluten-free diet (GFD). Adherence is difficult to assess and influenced by many factors. Identification of potential gluten exposures is essential, but no validated screening measures exist in pediatrics. The aim of this study was to develop and validate a measure screening for gluten exposure risk in pediatric patients with CeD. METHODS: The Gluten Exposure Risk Assessment (GERA) was developed in 3 phases. First, items were generated and refined by a modified Delphi process. Next, psychometrics, factor structure, and validity were examined in a sample of caregivers of pediatric patients younger than 18 years with CeD at 12 pediatric celiac centers. Finally, the final measure was tested on an independent sample population using confirmatory factor analysis and test-retest data. RESULTS: A total of 134 items were generated representing up to 6 domains, with 36 items selected for initial testing. Based on psychometrics and confirmatory factor analysis data from 484 caregivers, the final measure included a total of a single screening question and 9 validated items representing 2 domains (Home, Outside). Repeat testing on a separate sample (N = 369) confirmed factor structure and validity of the final measure (Comparative Fit Index = 0.96, Tucker–Lewis index = 0.95, root mean square error of approximation = 0.06). DISCUSSION: The GERA is a valid screening measure, completed by caregivers, for assessment of gluten exposure in children and adolescents with CeD following a GFD. GERA is a useful tool for evaluating the potential of risk of gluten exposure and potential need for intervention.

ABSTRACTObjectivesCeliac disease (CeD), an autoimmune disorder triggered by gluten ingestion, induces intestinal inflammation and varied symptoms. Treatment entails a strict gluten‐free diet (GFD), posing challenges for students, especially in schools with limited food choices. Nonadherence worsens symptoms, yet research on CeD's impact on students is scarce.MethodsThe CeliacKIDS study, conducted across 11 United States academic medical centers, evaluated gluten exposure risk in pediatric CeD patients via a cross‐sectional survey from August 2020 to August 2021. Participants recruited from treating institutions were approved by respective Institutional Review Boards.ResultsOne hundred and sixty children aged 5–18 (65% female, 34% male, 1% other) participated. Only 12% had GF food options at school, 31% brought their own for celebrations, and 41% lacked gluten free (GF) snacks after school. Thirty‐six percent lacked a 504 plan, with 5% misinformed. Hand hygiene concerns included 24% using sanitizer and 10% rarely washing hands before eating. Sixty‐two percent disclosed CeD, 35% when prompted, and 3% refused, mainly 13‐year‐old males. Two percent hesitated to request GF options, and 2% consumed potentially gluten‐containing food from friends.ConclusionMany US schools provide GF accommodations under the Americans with Disabilities Act (ADA) but lack national standards. Diverse GF options and education on GF‐safe practices are crucial for GFD adherence. Discrepancies in parent–child perceptions emphasize the need for better communication. Adolescents, particularly females aged 12–13 with 2+ years on a GF diet, face higher risks. Transparent family–school communication is vital for optimizing the school experience and ensuring GFD adherence. Comprehensive nationwide school training is essential for celiac patients' well‐being.

AbstractObjectivesThe prevalence of celiac disease (CeD) is increasing, yet it is still underdiagnosed, in part because of its heterogeneous presentation. Diagnostic criteria are evolving and management with strict adherence to a gluten‐free diet is challenging for many. We aimed to characterize the clinical presentation of CeD among a large multicenter cohort of pediatric patients and to identify factors associated with gluten‐free diet adherence.MethodsPatients with CeD aged 0–18 years were recruited from 11 United States health centers. Parents completed surveys about gluten‐free diet adherence and patient electronic health records were reviewed. Logistic regression analyses were performed to identify risk factors associated with gluten exposure.ResultsCharts were reviewed for 460 children with a median age of 6.4 years. Abdominal pain was reported in 57% of the cohort, but diverse symptoms were identified. Parent surveys were completed for 455 participants. Sixty‐five (14%) participants were at high risk for gluten exposure based on parental reports of weekly or daily gluten exposure or eating gluten by choice in the past year. Participants under the age of 5 years had a lower risk of gluten exposure, while participants without repeat serology testing 18 months after initial diagnosis were at higher risk of gluten exposure.ConclusionsIn a large, multicenter cohort of pediatric CeD patients, clinical presentation is highly variable, necessitating a high index of suspicion to make a diagnosis. Parent surveys indicate that 14% of patients are at high risk of gluten exposure, with patient age and lack of close follow‐up associated with gluten‐free diet adherence.

Objectives:Patients with Trisomy 21 (T21) commonly have gastrointestinal symptoms and diseases that prompt evaluation with esophagogastroduodenoscopy (EGD). Our objective is to characterize duodenal histological abnormalities in these patients when undergoing EGD. A secondary aim is to explore associations of histologic findings with different therapies.Methods:Patients 30 years old or younger with T21 who underwent EGD from 2000 to 2020 at 6 hospitals were included in this retrospective cohort study. Duodenal biopsies were categorized based on reported histopathology findings as normal or abnormal. Abnormal pathology reports were reviewed and categorized into villous atrophy (VA) and duodenitis without VA. The VA group was further categorized based on the presence or absence of celiac disease (CD).Results:We identified 836 patients with T21 who underwent EGD, 419 (50.1%) of whom had duodenal histologic abnormalities. At the time of the first (index) abnormal duodenal biopsy, 290 of 419 had VA and of those, 172 of 290 met CD diagnostic criteria, while 118 of 290 did not meet CD criteria (nonspecific VA). Among the patients with an abnormal biopsy, acid suppression at the time of the index biopsy was less common in patients with VA‐CD compared to patients without VA or patients with nonspecific VA (12.2% vs 45.7% vs 44.9%).Conclusions:Half of the T21 patients in this cohort had abnormal duodenal biopsies including a subgroup with nonspecific VA. In this cohort, acid suppression use was more prevalent in patients with abnormalities other than CD.
