Insights
Diagnosing pediatric celiac disease using endoscopy with biopsies yielded similar rates to serology-led diagnosis. Performing adequate intestinal biopsies during endoscopy is key to increasing celiac disease detection in children.
Area of Science:
- Pediatric Gastroenterology
- Gastrointestinal Pathology
- Immunology
Background:
- The diagnosis of celiac disease in children in the United States may be limited by a
Purpose of the Study:
- To investigate the rate of celiac disease diagnosed via upper endoscopy (esophagogastroduodenoscopy [EGD]) without prior positive celiac serology compared to diagnoses following positive serology.
Main Methods:
- Retrospective review of charts from children's first diagnostic EGDs between 2009-2013.
- Patients with confirmed celiac disease were categorized into histology-led diagnosis (positive EGD/positive serology) and serology-led diagnosis (positive serology/positive histology) groups.
Main Results:
- Of 761 EGDs reviewed, 15 children (1.97%) had confirmed celiac disease.
- No significant difference in demographics or symptoms was found between histology-led and serology-led diagnosis groups.
- The rate of celiac disease detection was comparable between histology-led (1.18%) and serology-led (0.79%) diagnosis approaches (P=0.273).
Conclusions:
- Endoscopy-led diagnosis rates for pediatric celiac disease are comparable to serology-led approaches.
- Adequate intestinal biopsies during diagnostic upper endoscopy are recommended to improve celiac disease detection in children.
- This suggests a potential underestimation of celiac disease due to diagnostic strategy.
Objectives:
The low rate of celiac disease diagnosed in children from the United States may be limited by the practice of "serology-led" diagnosis. The frequency of seronegative celiac disease is unknown, but is underestimated in children and may result in misdiagnosis of celiac disease. The aim of the present study was to investigate the rate of celiac disease after upper endoscopy (esophagogastroduodenescopy [EGD]) with no prior positive celiac serology compared with the rate of celiac disease followed by positive serology.
Methods:
Charts of all of the first diagnostic EGDs in children (2009-2013) were retrospectively reviewed. Patients with confirmed celiac disease were divided into 4 groups: group A, positive EGD/positive serology (histology-led diagnosis); group B, positive serology/positive histology (serology-led diagnosis); group C, positive histology followed by negative serology (control 1); and group D, positive serology followed by negative histology (control 2).
Results:
A total of 761 upper endoscopic charts were reviewed. Of these, 15 children were confirmed with celiac disease (1.97%). There was no significant difference in the demographic data or clinical symptoms between group A and group B. No significant difference was observed in the rate of celiac disease between histology-led celiac diagnosis (group A) and serology-led celiac diagnosis (group B) (1.18% vs 0.79%, P = 0.273).
Conclusions:
The rate of celiac disease in endoscopy-led diagnosis was comparable to that in the serology-led diagnosis, suggesting that to increase the detection of celiac disease in children, an adequate number of intestinal biopsies should be performed in every diagnostic upper endoscopic procedure.
