Clinical presentation and factors associated with gluten exposure in children with celiac disease.

Objectives: The 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.

Celiac disease in North America: What is the current practice of pediatric gastroenterology providers?

Objectives: While guidelines exist for the diagnosis and management of pediatric celiac disease (CeD), current practices in North America are not well-described. This study aimed to explore current practice patterns to identify gaps and direct future clinical, training and research initiatives.

Methods: A 23-item survey designed by the Celiac Disease Special Interest Group was distributed electronically to its members.

Eosinophilic esophagitis: Does age matter?

Objectives: Eosinophilic esophagitis (EoE) is often diagnosed in school-age children between 6- and 9-year-old. There is less known about those who are diagnosed with EoE that are younger than 6 years old. The objective of this study is to compare clinical presentation, comorbidities, and outcomes based on age at diagnosis of EoE.

Performance of an Artificial Intelligence Model for Recognition and Quantitation of Histologic Features of Eosinophilic Esophagitis on Biopsy Samples.

We have developed an artificial intelligence (AI)-based digital pathology model for the evaluation of histologic features related to eosinophilic esophagitis (EoE). In this study, we evaluated the performance of our AI model in a cohort of pediatric and adult patients for histologic features included in the Eosinophilic Esophagitis Histologic Scoring System (EoEHSS). We collected a total of 203 esophageal biopsy samples from patients with mucosal eosinophilia of any degree (91 adult and 112 pediatric patients) and 10 normal controls from a prospectively maintained database.

The Spectrum of Duodenal Histologic Findings in Patients With Trisomy 21: A Multicenter Study.

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.

The Characteristics of Isolated Bulb Celiac Disease in Children.

Objectives: Mucosal injury in celiac disease (CD) patients can be patchy, and up to 12% of CD patients can have mucosal changes limited to the duodenal bulb. Hence, recent guidelines recommend obtaining bulb biopsies in addition to distal duodenum. This study aimed to describe a cohort of children with isolated bulb CD and assess the benefit of separating bulb biopsies.

Effectiveness of Hepatitis B Vaccination for Patients With Inflammatory Bowel and Celiac Disease.

Background & Aims: Guidelines recommend measuring antibody (Ab) titers to hepatitis B virus (HBV) after vaccination for patients with inflammatory bowel disease (IBD) or celiac disease (CD) ("patients with IBD/CD") and revaccinating when titers are low. Few data, however, support this recommendation. We aimed to compare effectiveness of HBV vaccination (immunity and infection rates) for patients with IBD/CD vs matched referents.

Fecal Microbiota Transplantation for Clostridioides difficile Infection in Immunocompromised Pediatric Patients.

Objectives: We sought to evaluate the safety and effectiveness of fecal microbiota transplantation (FMT) for recurrent Clostridioides difficile infection (CDI) in pediatric immunocompromised (IC) patients.

Methods: This is a multicenter retrospective cohort study of pediatric participants who underwent FMT between March 2013 and April 2020 with 12-week follow-up. Pediatric patients were included if they met the definition of IC and were treated with FMT for an indication of recurrent CDI.

Effect of Esophagogastroduodenoscopy Volume and Gastric/Esophageal Pathology on the Rate of Lymphocytic Duodenosis Reporting in Children and Adolescents.

 It is not clear if the increase in the number of esophagogastroduodenoscopies (EGDs) performed has any significant effect on the rate of lymphocytic duodenosis (LD) reporting in children and adolescents and whether it correlates with abnormal gastric and/or esophageal pathology."  We performed a single-center retrospective study using the Mayo Clinic electronic health record and pathology database. We reviewed all EGD procedures performed in children and adolescents (<18 years) between January 1, 2000, and December 31, 2018, and identified two groups, the LD group and matched age and sex control group (normal duodenal biopsies).

Patient Satisfaction Scores Impact Pediatrician Practice Patterns, Job Satisfaction, and Burnout.

Patient satisfaction (PS) surveying has become a commonly used measure of physician performance, but little is known about the impact on pediatricians. To investigate our hypothesis that PS surveys negatively impact pediatricians, we conducted a survey at an academic children's medical center. Of 155 eligible physicians, 115 responded (response rate 74%).

Development and technical validation of an artificial intelligence model for quantitative analysis of histopathologic features of eosinophilic esophagitis.

Background: In an attempt to provide quantitative, reproducible, and standardized analyses in cases of eosinophilic esophagitis (EoE), we have developed an artificial intelligence (AI) digital pathology model for the evaluation of histologic features in the EoE/esophageal eosinophilia spectrum. Here, we describe the development and technical validation of this novel AI tool.

Methods: A total of 10 726 objects and 56.

Intrapyloric Botulinum Toxin A Injection for Gastroparesis and Functional Upper Gastrointestinal Symptoms in Children: Mayo Clinic Experience, Review of the Literature, and Meta-analysis.

Objective: We aimed to assess the efficacy of intrapyloric botulinum toxin A injection (IPBTI) in children with and without gastroparesis and to perform a meta-analysis and review of the literature.

Methods: We retrospectively searched our electronic health records to identify children (aged < 18 years) who underwent an esophagogastroduodenoscopy with IPBTI between 2007 and 2018 for persistent upper gastrointestinal tract symptoms. We included children with and without gastroparesis and excluded children with a history of gastrointestinal surgery, gastrointestinal obstruction, or mucosal disease that could explain their symptoms.

Vasopressors and Enteral Nutrition in the Survival Rate of Children During Extracorporeal Membrane Oxygenation.

Objectives: Nutrition support is essential in improving outcome and survival in children on extra corporal membranous support (ECMO). We aim to evaluate the association between the timing of enteral nutrition (EN) initiation and its impact on outcome.

Methods: We retrospectively reviewed the electronic health records of children (≤18 years) from November 2014 to November 2019 who were on veno-arterial ECMO for ≥48 hours.

Collagenous Gastritis: Characteristics and Response to Topical Budesonide.

Background And Aims: Collagenous gastritis (CG) is a rare disorder characterized by subepithelial collagen deposition in the stomach. Standard medications have been only moderately successful in treating CG. We report results of a large, retrospective, open-label noncontrolled study of topical budesonide for CG, with an aim of establishing an alternative therapy for the disease.

Celiac Disease: Risk of Hepatitis B Infection.

Objective: The aim of our study was to assess the response to hepatitis B virus (HBV) vaccination and the risk of HBV infection in patients with celiac disease (CD).

Patients And Methods: We performed a cross-sectional study using the National Health and Nutrition Examination Survey (NHANES) database (2009-2014) to assess the rate of HBV vaccination, immune response, and HBV infection risk in patients with and without CD. We also determined the rate of HBV infection via retrospective analysis of two cohorts: patients seen at Mayo Clinic (1998-2021), and a stable longitudinally observed cohort, the Rochester Epidemiology Project (REP; 2010-2020).

Clinical Implications for Children Developing Direct Hyperbilirubinemia on Extracorporeal Membrane Oxygenation.

Objective: Extracorporeal membrane oxygenation (ECMO)-associated direct hyperbilirubinemia (DHB) is likely multifactorial. The objective of this study is to assess the frequency and risk factors for developing direct hyperbilirubinemia while on ECMO, and its implication on the mortality of children.

Methods: We performed a retrospective study between January 2010 and January 2020.

Peripartum Antibiotics Exposure and the Risk of Autoimmune and Autism Disorders in the Offspring.

As the use of antibiotics during the peripartum period increases, the incidence of autoimmune disorders and autism spectrum disorders (ASDs) is also increasing. In this study, we aim to assess if antibiotic exposure during the peripartum period affects the incidence of autoimmune diseases and ASD in the offspring. We identified children (< 18 years of age) born in Olmsted County from January 1, 2003 through December 31, 2012.

Perianal magnetic resonance imaging findings and their potential impact on outcome in children with perianal fistulizing Crohn disease.

Background: Children with perianal fistulizing Crohn disease require intensive medical management but also have a higher risk for subsequent surgical interventions.

Objective: We performed a retrospective study to identify patient factors and perianal anatomical features by pelvic MR that are associated with surgical interventions in these children.

Materials And Methods: We included children with Crohn disease and perianal fistula who underwent pelvic MR with available, archived images and collected demographic, clinical and laboratory data.

Markers of Bile Acid Metabolism in Pediatric Diarrhea Predominant Irritable Bowel Syndrome and Healthy Controls.

Objectives: Excessive fecal bile acids in adults have been associated with diarrhea-predominant irritable bowel syndrome (IBS-D), but their role in pediatric IBS-D is unknown. Serum markers including 7α-hydroxy-4-cholesten-3-one (C4) and fibroblast growth factor-19 (FGF-19) were validated in adults to detect bile acid diarrhea (BAD) compared to 48-hour fecal bile acid collection (48FBA). Our aims were to assess fasting serum C4 and FGF-19 and 48FBA in a pediatric population, to compare measurements in IBS-D patients and healthy controls (HC), and to determine the prevalence of BAD among children with IBS-D.

Reproductive Characteristics and Pregnancy Outcomes in Hidden Celiac Disease Autoimmunity.

Introduction: Untreated symptomatic celiac disease (CD) adversely affects female reproduction; however, the effect of hidden CD autoimmunity is uncertain.

Methods: We identified women who were not previously diagnosed with CD and tested positive for tissue transglutaminase and endomysial antibodies between 2006 and 2011 in a community-based retrospective cohort study. We evaluated (i) the rate of adverse pregnancy outcomes and medical complications of pregnancy in successful singleton deliveries and (ii) reproductive characteristics in seropositive women without a clinical diagnosis of CD and age-matched seronegative women.

Role of Lactulose Rhamnose Permeability Test in Assessing Small Bowel Mucosal Damage in Children with Celiac Disease.

Increased gut permeability has been suggested in patients with celiac disease (CD). We aimed to compare gut permeability in children using the lactulose/rhamnose permeability test. We prospectively recruited 55 children into 3 groups; 27 in group 1 (children with newly diagnosed celiac disease, 12 in group 2 (siblings of children with celiac disease) and 16 in group 3 (control group).
