  • Title: [Influence of an acute hypercalcemia on the gastric secretion in duodenal ulcer, peptic ulcer of the jejunum and Zollinger-Ellison syndrome].
    Author: Arendt R.
    Journal: Z Gesamte Inn Med; 1975 May 15; 30(10):349-53. PubMed ID: 1199239.
    Abstract:
    In 36 patients with ulcer without Zollinger-Ellison-syndrome (25 patients with recurrent duodenal ulcer, 11 with an ulcus pepticum jejuni after B II-resection of the stomach) and 2 patients suffering from ulcus pepticum jejuni with an ascertained gastrinoma the secretion of acid was compared after stimulation of pentagstrin (6 mug/kg) and calcium (4 mg Ca++/kg/h). The secretion of hydrochloric acid was statistically significantly stimulated in all patients suffering from ulcer by the hypercalcaemia (increase of the serum calcium concentration from 5.0 +/- 0.3 mval/1 to 6.2 +/- 0.8 mval/1). But in patients suffering from ulcer with gastrinoma the stimulatory effect was larger than in such patients without autonomous source of gastrin: the calcium-stimulated secretion of hydrochloric acid was on the average in cases of duodenal ulcer 40% (2 to 68%), in the ulcera peptica jejuni 47% (17 to 75%), in the 4 comparative examinations of the two patients with Zollinger-Ellison-syndrome, however, always more than 100% (106 to 177%) of the pentagastrin-stimulated peak secretion. The comparative test of the pentagastrin and calcium-stimulated secretion of hydrochloric acid could be a help for the proof of autonomous places of the formation of gastrin.
