Gastrointestinal endocrine cell hyperplasia in celiac disease: a selective proliferative process of serotonergic cells

Abstract

Untreated celiac disease is characterized by gastrointestinal endocrine cell hyperplasia (ECH). This study investigated the constitutive nature of the ECH. Ten duodenal biopsies showing villous atrophy from adult celiacs were evaluated against ten sex- and age-matched controls. The mean number of endocrine cells per unit length of mucosa in the celiacs was compared with the control group using the Student t test. These values, respectively, were as follows: Churukian-Schenk method, 52.4 versus 29.6 (P = 0.001); Fontana-Masson, 32.5 versus 18.4 (P = 0.016); chromogranin, 33.4 versus 23.6 (P = 0.017); serotonin, 44.7 versus 26.7 (P = 0.006); somatostatin, 5.0 versus 5.4 (P = 0.631); and gastrin, 0.37 versus 0.37 (P = 1.000). There was thus ECH as shown by the first four stains with, in some areas, the endocrine cells continuously abutting against each other to form linear profiles. With respect to specific hormonal products, only serotonin showed ECH. These results suggest that the ECH in celiac disease is not a haphazard process but, instead, a selective proliferation of certain endocrine cell types.
