Serum gastrin and serum calcium concentrations were measured in 9 hemodialysis patients treated with 1-alpha-hydroxy vitamin D3 and in 15 control patients. Serum calcium and serum gastrin concentrations were significantly increased after 1 and after 5 months of treatment with 1-alpha-hydroxy vitamin D3. It is concluded that serum gastrin concentration is sensitive to a rise in calcium concentration within physiological range in patients with chronic renal failure.

High levels of serum calcitonin were found in patients with chronic renal failure. Serum calcitonin correlated directly with the phosphate to total calcium ratio; calcitonin levels correlated inversely with serum calcium in those patients on dialysis and directly with serum calcium in nondialysis patients. All patients had elevated serum gastrin. The high levels of serum calcitonin usually decreased following successful kidney transplantation. The pathophysiology of this hypercalcitonemia and its relationship to renal osteodystrophy and the disordered calcium metabolism of uremia remains to be elucidated.

Gastric function and histology were investigated in 24 patients with untreated chronic renal failure. At endoscopy nine patients had oesophagitis, 12 patients were considered to have gastritis, and the duodenum appeared inflamed in 20 patients. Endoscopic biopsies were taken at standard sites in the stomach and duodenum; gastritis was found in all patients, and 17 patients had duodenitis. Stimulated acid secretion was impaired in seven out of 20 patients and acid hypersecretion was found in a further two patients. Pepsin output correlated well with acid output in these patients. Fasting serum gastrin levels were elevated in 12 of the 19 patients tested. Patients with atrophic gastritis had low acid outputs and hypergastrinaemia, and when extensive gastritis was present, the patients tended to have more severe renal failure and hyposecretion of acid. Three patients were studied again after regular haemodialysis or renal transplantation and were found to show marked endoscopic and histological improvement.

Antral somatostatin- and gastrin-producing cells (D and G cells) were studied in a group of patients with chronic renal failure (CRF) in comparison with a control group. Gastric acid secretion and serum gastrin, phosphate, and parathormone (PTH) levels were also evaluated in every patient. The group with CRF showed a mild increase both in G- and in D-cell denisty. In this group serum phosphate and PTH levels were higher than normal, showing hyperparathyroidism in every patient. A direct correlation was found between G-cell density and parathyroid function in patients with CRF. Hyperparathyroidism, therefore, seems to play a role in the mechanism of increased serum gastrin levels in CRF.

Whisky (25-50 ml) increased plasma levels of immunoreactive calcitonin (iCT) in seventeen of nineteen patients with chronic renal failure. The effect was greater in patients with high levels of iCT than in those with normal levels. Changes in plasma iCT were not related to changes in calcium, phosphate or immunoreactive gastrin, but were inhibited by the prior administration of propranolol.

The interrelationship between serum gastrin and serum calcitonin concentrations was studied in 73 patients with chronic renal failure. In both haemodialyzed and non-dialyzed patients increased serum concentrations of these hormones were found compared with normal controls. In non-dialyzed patients with creatinine clearance above 10 ml/min a highly significant correlation between serum gastrin and creatinine clearance was found, whereas no correlation was found in patients with creatinine clearance below 10 ml/min. Between serum gastrin and serum calcitonin, a significant positive correlation was found in non-dialyzed patients. These findings may be explained by a relationship between the two hormones or be secondary to a decreased elimination due to the reduced renal function.

In 18 patients with acute renal failure and 11 patients with chronic renal insufficiency serum gastrin levels were estimated before and after a test meal. The results were compared with those obtained in a group of 52 healthy subjects. It was stated that patients with acute as well as chronic renal failure display a "physiological" increase of serum gastrin after stimulation by a test meal. In contrast to healthy subjects the post-test meal gastrin curves in patients with chronic and acute renal insufficiency during the anuric/oliguric phase started from significantly higher fasting values. From the results obtained it seems that diminished renal clearance of gastrin by the insufficient kidneys is only partially responsible for the elevated fasting values found in anuric/oliguric patients with acute renal failure or patients with chronic renal insufficiency.

Many alterations in metabolic and endocrine function occur in end-stage renal disease. Glucose intolerance is almost always present with uremia; it improves shortly after institution of regular hemodialysis. Hyperlipidemia (type IV) is prevalent, and atherosclerotic cardiovascular disease causes death in about 50% of patients receiving long-term hemodialysis. Although plasma levels of growth hormone usually are elevated, children with chronic renal failure show growth retardation. The occurrence of thyroid disorders is difficult to determine, since many clinical features of uremia are similar to those of hyperthyroidism and hypothyroidism. The incidence of duodenal ulcer is high, possibly due to high gastrin levels. Sex hormone disturbances are common. Anemia is a constant feature of chronic renal failure; patients usually tolerate it well.

Both gastrin and acid responses to antral stimulation by meat extracts (Oxo) were studied in 15 undialysed males with chronic renal failure (CRF). Eighteen sex and age-matched duodenal ulcers (DU) served as controls. Oxo increased acid and plasma gastrin in both groups. The rise in plasma gastrin was larger in CRF than in DU. The pattern of gastrin response in CRF suggests accumulation of gastrin in the plasma probably related to impaired renal inactivation of the hormone. Five CRF had large acid responses representing 40 to 90 percent of their maximal secretory capacity. Antral function should be measured in CRF before haemodialysis or renal transplantation.

Fasting blood gastrin level among various clinical entities was measured by means of radioimmunoassay. Hypergastrinemia of various degrees was found in some cases of chronic renal failure. During angiography arteriovenous difference of gastrin level was investigated in the kidney in 22 patients without renal diseases. The high rate of gastrin removal from the blood circulation by the kidney was also confirmed in the synthetic human gastrin 1-17 (SHG 1-17) infusion experiment in dogs. In this study, hypergastrinemia seen in renal diseases was thought to be caused partly by impaired gastrin metabolism in the kidney.
