Case report on the successful gastric ulcer treatment of a patient with primary hyperparathyroidism with the H2-receptor antagonist cimetidine. After four weeks of therapy with 0.8 g/d cimetidine stomal ulcerations were seen by x-rays and endoscopy to be healed. The patient was discharged on a regimen of 400 mg daily of oral cimetidine. Peptic ulcer did not recur after 1/2 year of treatment with this H2-receptor antagonist, although the signs of primary hyperparathyroidism were still present.

It is well known that primary hyperparathyroidism is often associated with peptic ulcer. The purpose of this study is to confirm the relationship between the gastrin-levels before and after parathyroidectomy in fourteen patients with primary hyperparathyroidism, and to determine the localization of gastrin in the surgically resected parathyroid tumor. The results obtained were as follows: 1) Three patients had peptic ulcer (gastric ulcer and duodenal ulcer), the incidence being 21%. 2) The basal serum gastrin levels were 123.0% +/- 68.1 pg/ml before operation and decreased to 90.2 +/- 44.5 pg/ml after operation. In the 3 patients with slightly elevated gastrin levels, the mean level before operation was 209.1 +/- 61.2 pg/ml. The gastrin level decreased to 116.4 +/- 62.0 pg/ml after operation. 3) Gastrin immunoreactivity was detected in 10 out of 14 tumors and its localization was at the periphery of tumor cells. From these results, we conclude that extragastric gastrin secretion from parathyroid tumors may be one of the cause of peptic ulcer in patients with primary hyperparathyroidism.

The prevalence of peptic ulcer disease was retrospectively analysed in 35 patients affected by primary hyperparathyroidism consecutively observed from 1977 through 1987. Eight of the examined patients (22.8%) had peptic ulcer (7 duodenal and 1 gastric ulcer), that in five cases (14%) represented the first clinical manifestation of the endocrine disease. A Zollinger-Ellison syndrome was demonstrated in three cases (8.5% of the total series, 37% of the patients with ulcer). There was no difference in calcium, gastrin and parathormone serum level between patients with and without ulcer, excluding patients with Zollinger-Ellison syndrome. These data confirm the high prevalence of peptic ulcer disease in hyperparathyroidism, but the mechanism causing this association remains to be elucidated.

A case of Zollinger-Ellison syndrome produced by gastrinoma in the duodenum accompanied by multiple endocrine neoplasia type-1 (MEN-1) is reported. A 46 year-old female underwent distal gastrectomy due to gastric ulcer 5 years ago. As ulceration of the residual stomach recurred, further examination was performed. Hyperprolactinemia, hypergastrinemia, primary hyperparathyroidism, pancreatic tumor, and duodenal carcinoid were evident, and the diagnoses of Zollinger-Ellison syndrome and MEN-1 were established. The origin of the gastrin secretion was suspected to be from the pancreatic tumor, so sampling of the portal blood was performed. As lesion on the gastrinoma in the pancreas could not be identified, total parathyroidectomy was performed for primary hyperparathyroidism. The level of the gastrin secretion, however, remained high. Partial resection of the duodenum for the duodenal carcinoid and a distal pancreatectomy were carried out concurrently. Immunohistochemical study of the anti-gastrin antibody revealed duodenal tumor cells. Initially, the gastrinoma was thought to be in the pancreas, however, the lesion accompanied with MEN-1 and the Zollinger-Ellison syndrome had occurred in the duodenum.

The aim of this study was to assess the spectrum of radiographic findings in primary hyperparathyroidism (PHPT). The study group consisted of 16 women and 7 men whose Ca levels were at least two or three times higher than normal. The average age was 55.3 in women and 49.4 in men. We detected carcinoma in 1, hyperplasia in 1, multiple adenomas in 4, single adenoma in 17 patients. The most common finding in the skeletal system was the decreased bone mineral density (BMD) and the complete loss of the lamina durae dentium. BMD was found lower in women than in men. This result attributed the increased number of postmenopausal patients in our study group. The second most common finding in our study group was subperiosteal bone resorption. Brown tumors (BTs) were located at maxilla in one, widespread in one, mandibula in two, long tubular bones in four patients. Renal stone disease was found in five, spastic colon in two, gastric ulcer in one, mitral valve calcification in one patients. We demonstrated no pathologic changes consistent with PHPT in remaining seven patients.
