Zollinger-Ellison syndrome and other gastric acid hypersecretory states in which a specific etiology is identified are defined as a basal acid output of greater than 15.0 meq/hr. To determine the level of basal acid output that defines idiopathic gastric hypersecretion, basal acid outputs were investigated in normal subjects and patients with duodenal ulcers, and functional and statistical definitions for idiopathic gastric acid hypersecretion were developed. Sixty-five normal subjects were evaluated to define idiopathic gastric acid hypersecretion on a statistical basis, and 22 patients with refractory duodenal ulcers were evaluated to define idiopathic gastric acid hypersecretion on a functional basis. Mean basal acid output for the 65 normal subjects was 3.0 +/- 2.7 meq/hr. Even though the mean basal acid output for the group of 28 normal male subjects was slightly higher than for the group of 37 normal female subjects, the groups were not significantly different. The 95% confidence interval around the mean basal acid output for all normal subjects was 2.4-3.7 meq/hr, with little difference between the male and female groups. The mean basal acid output plus two standard deviations and the mean basal acid output plus three standard deviations for the 65 normal subjects were 8.4 meq/hr and 11.1 meq/hr, respectively. Of 109 patients with active duodenal ulcers treated for eight weeks with standard doses of antisecretory medication, 22 showed no healing as documented by endoscopy. The mean basal acid output for these 22 patients with nonhealed duodenal ulcers was 18.7 meq/hr (range 10.1-49.1 meq/hr) while mean basal acid output for the 87 patients with healed duodenal ulcers was 7.5 meq/hr (range 0.0-27.9 meq/hr). The difference in mean basal acid output between these two groups was statistically different (P < 0.001). All patients with refractory duodenal ulcers had basal acid outputs of greater than 10.0 meq/hr. Our results indicate that the definition for idiopathic gastric acid hypersecretion should be a basal acid output of greater than 10.0 meq/hr, since, based on refractory duodenal ulcer disease, the functional definition for idiopathic gastric acid hypersecretion is a basal acid output of greater than 10.0 meq/hr, which in our data also corresponds well to the statistically defined range of basal acid output in normal subjects.
