RESUMO
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. METHODS: Patients 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. RESULTS: Charts 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. CONCLUSIONS: In 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.
RESUMO
Gluten challenge is an essential clinical tool that involves reintroducing or increasing the amount of gluten in the diet to facilitate diagnostic testing in celiac disease (CD). Nevertheless, there is no consensus regarding the applications of gluten timing, dosing, and duration in children. This review aims to summarize the current evidence, discuss practical considerations, and proposes a clinical algorithm to help guide testing in pediatric patients. Childhood development, social circumstances, and long-term health concerns must be considered when identifying a candidate for gluten challenge. Based on previous studies, the authors suggest baseline serology followed by a minimum of 3-6 grams of gluten per day for over 12 weeks to optimize diagnostic accuracy for evaluation of CD. A formal provider check-in at 4-6 weeks is essential so the provider and family can adjust dosing or duration as needed. Increasing the dose of gluten further may improve diagnostic yield if tolerated, although in select cases a lower dose and shorter course (6-12 weeks) may be sufficient. There is consensus that mild elevations in celiac serology (<10 times the upper limit of normal) or symptoms, while supportive are not diagnostic for CD. Current North American Society for Pediatric Gastroenterology, Hepatology and Nutrition guidelines recommend histologic findings of intraepithelial lymphocytosis, crypt hyperplasia, and villous atrophy as the accurate and most appropriate endpoint for gluten challenge.

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.

Intussusception is the most common cause of gastrointestinal obstruction in children and typically presents with acute abdominal pain. Intussusception usually occurs in children under the age of 3 in the ileocecal region. Over the past 5 years, multiple patients at the Children's Hospital of Philadelphia have been diagnosed with both intussusception and biopsy-confirmed celiac disease (CD). Intussusception may be a presenting sign of pediatric CD and should raise clinical suspicion for celiac screening, especially if it is a small bowel-small bowel intussusception that occurs after the age of 3 in a malnourished patient.

The aim of the study was to determine the correlation between duodenal mucosal biopsies and tissue transglutaminase immunoglobulin A (tTG-IgA) levels in pediatric patients with biopsy-confirmed celiac disease (CD) and eosinophilic gastrointestinal disorders (EGID) who have had repeat duodenal biopsies after initiating a gluten-free diet. Methods: A retrospective chart review was performed of children with CD and EGID seen at the Children's Hospital of Philadelphia between 2003 and 2018. Data collected included duodenal biopsy pathology, celiac serology including tTG-IgA, and symptom reports. Duodenal healing was defined as normal villous architecture and no intraepithelial lymphocytes. These data were compared with tTG-IgA level. Data were analyzed with Fisher exact test and t test methods. Results: Thirty-nine patients had normal IgA and diagnoses of both CD and EGID. At second biopsy, 44% (17/39) of patients showed no histologic evidence of active CD and 36% (14/39) of patients had negative tTG-IgA values. Sixty percent (9/15) of patients with no evidence of CD on biopsy had abnormal tTG-IgA levels, and 57% (8/14) of patients with normal tTG-IgA levels had evidence of active disease on biopsy. Conclusions: The data show that an abnormal tTG-IgA drawn after initiation of a gluten-free diet is not correlated with duodenal mucosal injury in pediatric patients with CD and EGID. This suggests that serologic surveillance with tTG-IgA is not sufficient to monitor CD intestinal healing in this patient cohort. Persistent elevations of tTG-IgA in CD patients with normal duodenal biopsies should prompt investigation into other potential causes.

OBJECTIVES: TSLP has been shown to be associated with eosinophilic esophagitis (EoE). Specifically, children with EoE often have the nucleotides AA or AG instead of GG at the single nucleotide polymorphism position RS3806932. Presently, the phenotypic characteristics in EoE children with the TSLP EoE risk allele are unknown. METHODS: A retrospective analysis was performed of all children with EoE who had TSLP genotyping at The Children's Hospital of Philadelphia from 2008-2014. EoE food allergen triggers, presence of atopic features, IgE mediated food allergy and skin prick testing results were reviewed. The number and type of EoE food allergen triggers were compared with genotype using chi-square analysis. Primary cell cultures from EoE patients with or without the risk allele were stimulated with ovalbumin and TSLP secretion was measured by ELISA. RESULTS: Fifty three of 309 patients were found to have no copies of the TSLP risk allele, whereas 256 patients were found to have one or more copies of the risk allele. There was an increase in the number of patients with three or more EoE food allergens among those who were either homozygous or heterozygous for the risk allele compared to those without the risk allele (P < 0.0001). This was independent of their atopic background. Primary cultures from patients homozygous for the risk allele had greater TSLP secretion than those isolated from heterozygous patients. CONCLUSIONS: The TSLP risk allele is associated with having multiple EoE food allergen triggers. This novel EoE genotypic-phenotypic correlation may guide future treatment for those with the TSLP risk allele.
RESUMO
Eosinophilic esophagitis (EoE) is an atopic disease that is characterized by an isolated infiltration of eosinophils into the epithelium of the esophagus and is triggered by specific allergens. Patients should undergo an upper endoscopy with biopsy after 6 to 8 weeks of treatment with a proton pump inhibitor in order to make the diagnosis of EoE. Eosinophilic gastroenteritis is a pathologic eosinophilic infiltration of any portion of the gastrointestinal tract, and eosinophilic proctocolitis is an eosinophilic infiltration in the colon alone.

OBJECTIVE: The relation between food allergies and eosinophilic esophagitis (EoE) is well established. Aeroallergens may also contribute to the development of EoE; however, there are limited data to support or refute this hypothesis. The objectives of this pilot study were to determine whether there is a seasonal variation in the onset of symptoms and/or diagnosis of EoE and whether these variations correlate with a specific pollen concentration within New York City. METHODS: We performed a retrospective chart review to identify all pediatric patients at New York Presbyterian Weill Cornell Medical Center diagnosed with EoE between 2002 and 2012. Sixty-six patients were identified and 28 were excluded. Cases were classified by both date of initial symptoms and date of histologic diagnosis. Pollen counts from a certified New York City counting station and the percentage of EoE cases were collated monthly and seasonally and compared. RESULTS: There was a seasonal variation in onset of symptoms and diagnosis of EoE, with the highest number of patients reporting onset of symptoms of EoE in July to September, and those being diagnosed with EoE in October to December. There was a seasonal correlation between peak levels of grass pollen and peak onset of EoE symptoms, which were both highest in July to September. The diagnosis of EoE peaked one season later. CONCLUSIONS: The study findings suggest that there is a correlation between specific aeroallergens and both the onset of symptoms and time of diagnosis of patients with EoE.

OBJECTIVE: Investigate the influence of perinatal factors on short- and long-term outcomes for infants born at 23 weeks of gestation. STUDY DESIGN: This is a retrospective study over a 25-year period (1987-2011) of 87 successfully resuscitated infants at 23 weeks of gestation. We investigated the effects of poor prenatal care, race, gender, chorioamnionitis, antenatal corticosteroids, delivery route/location, low 5-minute Apgar score, birth weight, and multiple births on short- and long-term outcomes. RESULTS: The mortality rate was 43% (37/87). A total of 88% (44/50) of the survivors were followed at 2 years corrected age with 66% (29/44) diagnosed with a moderate-to-severe neurological impairment. Outborn and multiple birth infants had significantly higher mortality (p-value 0.042 and 0.006, respectively). Lack of exposure to antenatal steroids and lower birth weight significantly increased the disability score (p-value 0.042 and 0.003, respectively). CONCLUSION: Multiple perinatal factors significantly influence outcomes at the threshold of viability.

Tools for predicting growth of Staphylococcus aureus, Salmonella, and Escherichia coli O157:H7 (THERM; temperature history evaluation for raw meats) have been developed using ground pork and sausage. THERM tools have been tested with three types of pork sausage but not with other pork products or during sequential temperature abuse periods. We conducted inoculation studies (five strains each of S. aureus and/or Salmonella plus E. coli O157:H7) with simulated cooling of warm sausages, inprocess warming of bratwurst, isothermal temperature abuse of pork frankfurter batter, and two sequential periods of 13, 15.6, or 21.1 degrees C temperature abuse of breakfast sausage, natural (additive-free) chops, and enhanced (phosphate solution-injected) loins. In sequential temperature abuse studies, a temperature abuse period (> or =24 h) occurred before and after either refrigeration (5 degrees C for 24 h), or freezing (-20 degrees C for 24 h) and thawing (24 h at 5 degrees C). Pathogen growth predictions from THERM developed using ground pork and sausage were compared with experimental results of 0 to 3.0 log CFU of growth. Across all temperature abuse conditions, qualitative predictions (growth versus no growth) made using the pork tool (n = 133) and the sausage tool (n = 115) were accurate (51 and 50%, respectively), fail-safe (44 and 50%), or fail-dangerous (5 and 0%). Quantitative predictions from the two tools were accurate (29 and 22% , respectively), fail-safe (59 and 73%), or fail-dangerous (12 and 5%). Pathogen growth was greater during the second sequential temperature abuse period but not significantly so (P > 0.05). Both THERM tools provide useful qualitative predictions of pathogen growth in pork products during isolated or sequential temperature abuse events.
