It has been suggested that the rise in serum pepsinogens is mediated by the omeprazole-induced increase in serum gastrin. This study was undertaken to determine the role of gastrin in hyperpepsinogenemia induced by antisecretory therapy. We have studied the effect of a 5-day course of 40 mg of omeprazole daily on fasting serum gastrin and pepsinogen A and C levels in 14 patients with an antrectomy and a Billroth I anastomosis (n = 8) or a Billroth II anastomosis (n = 6). In antrectomized patients omeprazole failed to induce any increase in basal serum gastrin. On the other hand, omeprazole increased significantly serum pepsinogen A levels in both Billroth I and II patients, while the rise in serum pepsinogen C level was significant in Billroth I, but just failed to reach statistical significance in Billroth II patients. We conclude that the stimulation of serum pepsinogens A and C by a short-term treatment with omeprazole is not mediated by increases in serum gastrin. This study further shows that omeprazole stimulates gastrin release only from the antrum and not from extra-antral sources.<\/jats:p>","DOI":"10.1159\/000201027","type":"journal-article","created":{"date-parts":[[2009,2,7]],"date-time":"2009-02-07T01:50:30Z","timestamp":1233971430000},"page":"139-142","source":"Crossref","is-referenced-by-count":6,"title":["Effect of Short-Term Administration of Omeprazole on Serum Gastrin and Pepsinogens in Antrectomized Patients"],"prefix":"10.1159","author":[{"given":"J.L.","family":"Meijer","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.B.M.J.","family":"Jansen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"Biemond","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.B.H.W.","family":"Lamers","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,2,5]]},"container-title":["Digestion"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/201027","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000201027","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T08:39:59Z","timestamp":1777538399000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000201027"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,2,5]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000201027","archive":["Portico"],"relation":{},"ISSN":["0012-2823","1421-9867"],"issn-type":[{"value":"0012-2823","type":"print"},{"value":"1421-9867","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,2,5]]}}}
