  • Title: Reassessment of enteric endocrine cell hyperplasia in celiac disease.
    Author: Johnston CF, Bell PM, Collins BJ, Shaw C, Love AH, Buchanan KD.
    Journal: Hepatogastroenterology; 1988 Dec; 35(6):285-8. PubMed ID: 3215624.
    Abstract:
    Celiac disease is characterized by reversible, gluten-induced, architectural abnormalities of the intestinal mucosa. Villus atrophy is compensated for by an increase in the number of proliferating cells and an increase in crypt cell production rate, resulting in increased crypt length and girth. Several authors, employing various methods of quantitation, have reported enteric endocrine cell hyperplasia in celiac disease. The present study has re-evaluated enteric endocrine cell status in this disorder by employing methods of quantitation which more accurately take account of alterations of crypt morphology than those previously used. Numbers of endocrine cells expressed as cells per unit of crypt length are not increased in the celiac biopsies when contrasted with those from controls. Indeed, numbers of cells immunoreactive for gastrin, GIP, motilin and somatostatin were reduced in the celiac mucosa. Endocrine cell hyperplasia in the celiac small bowel is not as marked as was previously thought, and may lag behind that of the enterocyte population.
