The role of antral histopathology in diagnosing paediatric celiac disease

Abstract

The aim of this study was to evaluate the diagnostic potential of gastric antrum histology in children suspected of having celiac disease (CD). The present retrospective study was performed on 224 patients who were suspected of having CD and had several duodenal and one gastric antrum biopsies. They were divided into 2 groups based on the definite diagnosis of CD. The statistical analysis was performed using SPSS version 22 software. Receiver operating characteristic (ROC) curves were drown and the area under the curves (AUCs) was calculated. Based on MARSH criteria, out of 224 patients, 124 were diagnosed as definite CD and 100 patients comprised the non-celiac group. The AUC for the mean of all pathological tests was estimated to be 0.90 (p < 0.001). The pooled AUC for the combination of 3 pathologic findings with the highest AUCs (cell, crypt, and gland size) was estimated to be 0.89 (p < 0.001). We observed that the histological changes we found in the gastric antrum were identical to those found in the duodenum of paediatric CD patients. Because providing a biopsy from the gastric antrum is easier than getting multiple biopsies from the duodenum, we suggest using the criteria mentioned in this study in other studies with larger sample sizes.
