Abstract
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.
