Autoimmune Atrophic Gastritis With Hypergastrinemia
Southern Medical Journal, 1976Elevation in fasting serum gastrin levels was found in three patients being evaluated for persistent upper abdominal pain without radiographic evidence of peptic ulcer disease. Fiberoptic endoscopy of the upper gastrointestinal tract in each patient revealed characteristic changes of chronic atrophic gastritis.

Cimetidine blocks antacid-induced hypergastrinemia
Gastroenterology, 1986The effects on fasting serum gastrin concentrations of hourly doses of magnesium and aluminum hydroxide antacid, with and without intravenous cimetidine, were determined in 8 patients with duodenal ulcer disease. Gastrin levels rose significantly over 10 h when antacid was given either as a bolus of 30 ml every hour or as a constant infusion of 0.5 ml ...

Effect of hypergastrinemia on pancreatic carcinogenesis
The American Journal of Surgery, 2002Previous studies in our laboratory demonstrated that pancreatic carcinomas in rodents express receptors for the peptide hormone gastrin that are not present in normal adult pancreas. In view of an abundant literature suggesting that gastrin may promote growth of various gastrointestinal tissues and tumors, the effect of hypergastrinemia on the process ...

Marked Hypergastrinemia in Gastric Outlet Obstruction
Journal of Clinical Gastroenterology, 1989We report a 45-year-old woman with chronic peptic ulcer disease and multiple episodes of bowel obstruction, who was admitted with gastric outlet obstruction. Because of gastric hypersecretion, a diagnosis of Zollinger-Ellison syndrome was suspected and an initial serum gastrin of 1,251 pg/ml supported this diagnosis.

Hypergastrinemia in children with duodenal ulcer
Journal of Pediatric Surgery, 1988Serum gastrin concentrations were determined in 25 children with duodenal ulcer (DU) and 25 normal children. Fasting values were significantly higher in DU children (mean +/- SE = 60.4 +/- 9.7 pg/mL) than in controls (mean +/- SE = 38.0 +/- 4.2 pg/mL; P less than .05).

Gastric carcinoids in patients with hypergastrinemia
Journal of the American College of Surgeons, 2004Hypergastrinemia in patients with pernicious anemia is a major regulator contributing to enterochromaffin-cell hyperplasia and, ultimately, to gastric carcinoids.Between 1990 and 2003, we studied 8 women and 10 men with pernicious anemia and gastric carcinoids; their mean age was 50 years. Serum gastrin levels ranged from 740 to 4,000 pg/mL (mean 1,000

[Postoperative hypergastrinemia].
Chirurgia italiana, 1980After reviewing the more recent acquisitions on the physiology and pathophysiology of gastrin, the authors concentrate on situations of hypergastrinemia, which they divide into a hyperhydrochloric and a hypohydrochloric variety. Among the former, which they subdivide into preoperative and postoperative, the authors discuss problems of differential ...

Antral Hypergastrinemia – A Report of Three Cases
Digestion, 1987Three patients with juxtapyloric ulcers and hypergastrinemia are presented. Fasting and food-stimulated serum gastrin concentration (SGC) were measured in 1970, 1972 and 1973 before the primary ulcer operation (selective gastric vagotomy and Jaboulay gastroduodenostomy; SGV + GD).

Hyperparathyroidism and hypergastrinemia revisited.
Surgery, 1985The prevalence of hypergastrinemia was determined in 38 consecutive patients with proved primary hyperparathyroidism. Uncorrected serum calcium levels ranged from 2.6 to 4.0 mmol/L and parathyroid hormone levels from 260 to 8750 ng/L (normal less than 600 ng/L).

Hypergastrinemia increases gastric epithelial susceptibility to apoptosis
Regulatory Peptides, 2008Plasma concentrations of the hormone gastrin are elevated by Helicobacter pylori infection and by gastric atrophy. It has previously been proposed that gastrin acts as a cofactor during gastric carcinogenesis and hypergastrinemic transgenic INS-GAS mice are prone to developing gastric adenocarcinoma, particularly following H. pylori infection.
