Endoscopic and histologic findings in the upper gastrointestinal tract of children with coeliac disease.
Frequency of mucosal damage to the esophagus, stomach, and duodenum was investigated in 176 children with coeliac disease (CD) during 230 upper GI endoscopies performed to obtain duodenal biopsy specimens and was compared with findings in 230 age-matched children who underwent endoscopy for upper GI complaints without CD (non-CD patients). To evaluate a possible association with gluten ingestion, we then compared frequency of mucosal damage in patients on a gluten-containing diet and those on a gluten-free Diet (GFD). In children with CD, frequency of esophageal damage seen at endoscopy and of peptic esophagitis shown by histology were significantly lower than in non-CD patients (p < 0.01) due to the very low frequency of mucosal damage in CD children on GFD; however, frequency of columnar metaplasia was significantly higher (p < 0.05). At endoscopy, CD children had a significantly lower frequency of gastric abnormalities, but histology showed a higher prevalence of superficial chronic gastritis (SCG; p < 0.01). SCG was associated with gluten ingestion, since its frequency in CD children on GFD was similar to the frequency in non-CD patients. At endoscopy, frequency of duodenal mucosal damage was similar in CD and non-CD patients. In addition to villous atrophy, histology showed a significantly higher frequency of duodenitis in CD children on a gluten-containing diet (p < 0.001 vs. non-CD patients; p < 0.05 vs. CD children on GFD). Our findings show that the mucosa of the whole upper GI tract can be damaged in CD patients and that the prevalence of some changes is higher with a gluten-containing diet.
