  • Title: Gastric endocrine cells in omeprazole-treated and untreated patients with the Zollinger-Ellison syndrome.
    Author: Bardram L, Thomsen P, Stadil F.
    Journal: Digestion; 1986; 35 Suppl 1():116-22. PubMed ID: 3792668.
    Abstract:
    We have investigated the gastric endocrine cells in 19 patients with the Zollinger-Ellison syndrome. Six received a long-term treatment with omeprazole, 5 one with H2 receptor antagonists and 8 had no medical treatment. Fifteen patients (79%) had hyperplasia of the endocrine cells in the oxyntic mucosa independent of treatment. The hyperplasia involved both enterochromaffin-like (ECL) and D1 cells and was positively related to the duration of disease (p less than 0.05). The duration of hypergastrinaemia was longer in the omeprazole-treated patients, but the hyperplasia was not significantly more pronounced in these patients. Gastric carcinoid tumours consisting mainly of ECL cells are rare in man and are most often seen in states of hypergastrinaemia such as chronic atrophic gastritis. It has seldomly been reported in Zollinger-Ellison patients; but now, when potent antisecretory drugs make it possible to avoid total gastrectomy, a raised incidence might result, and an increased attention to this aspect seems appropriate.
