[Gluten-sensitive enteropathy and functional dyspepsia].

Gluten-sensitive enteropathy (GSE) is increasingly diagnosed in adults. The symptoms of this disease can overlap with those of functional dyspepsia. The prevalence of GSE in dyspepsia has been reported to be 1.2-6.2% and could be higher if the entire spectrum of lesions related to gluten sensitivity, including lymphocytic enteropathy, is considered. Patients with dyspepsia secondary to GSE could be mistakenly diagnosed with functional dyspepsia unless upper gastrointestinal endoscopy is completed with duodenal biopsy and immunostaining for intraepithelial lymphocytes. A missed diagnosis could have major consequences in terms of morbidity and mortality and quality of life. Consequently, endoscopic study of patients with dyspepsia should be completed by duodenal biopsy when there are symptoms suggestive of GSE.
