Abstract

Background. Iron deficiency anemia (IDA) is a recognised feature of celiac disease (CD) in adults and can be its only presentation. Aim. To define the prevalence of CD in Moroccan adult patients with IDA of obscure origin and to determine the yield of small bowel biopsy performed during routine endoscopy. Methods. 437 patients with IDA of obscure origin were included. 4 endoscopic mucosal biopsies were taken from the second part of duodenum and 2 biopsies from antrum and fundus, respectively. Endoscopic aspect and severity of anemia were correlated with histological diagnoses using coefficient Kappa. Results. 29 out of 437 patients (6.63%) had CD. Endoscopic aspect was normal in 66%, a mosaic pattern of mucosa in 17%, and scalloping of the small bowel folds in 17%. 12 patients had Marsh III, 8 had Marsh II, 6 had Marsh I, and 3 had Marsh IV lesions. There was no correlation between degree of anemia, endoscopic aspect, and severity of duodenal lesions . Conclusion. Routine duodenal biopsy gives an additional 6.63% diagnostic benefit of CD and should be indicated in all patients with IDA. The finding of normal endoscopic appearance of mucosa should not preclude duodenal biopsies.
