High Prevalence of Celiac Disease in Patients with Type 1 Diabetes Detected by Antibodies to Endomysium and Tissue Transglutaminase
Bibliographic record
Abstract
OBJECTIVE: To establish the prevalence of celiac disease (CD) in children with type 1 diabetes in British Columbia. PATIENTS AND METHODS: Two hundred thirty-three children with type 1 diabetes were prospectively screened for CD using blind testing with the current 'gold standard', immunoglobulin A endomysium antibody (EmA), and the novel immunoglobulin A tissue transglutaminase (tTG) antibody. Those children with positive results were offered small bowel biopsy; a gluten-free diet was recommended if CD was confirmed. RESULTS: Nineteen children were positive for EmA and had an elevated tTG level. One patient from this group was already known to have CD, and the other 18 patients consented to biopsy. One biopsy was normal, three biopsies demonstrated elevated intraepithelial lymphocyte counts with normal morphology and 14 biopsies had morphological changes consistent with CD. Growth parameters were normal in all patients, and nine of 19 children who were positive for EmA were asymptomatic. Seven patients had mild elevation of tTG levels alone. Two children from this latter group had normal biopsies, and five declined biopsy. CONCLUSIONS: At least 14 new cases of CD were detected in addition to four known cases, yielding an overall biopsy-confirmed prevalence of CD of 7.7% (18 of 233). The present study confirms that CD is as prevalent in the pediatric type 1 diabetic population in British Columbia as it is in Europe. Serological screening of these children is important because many children have no symptoms or signs suggestive of CD. This study suggests that tTG serology may also be useful in monitoring response and compliance with a gluten-free diet.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
