[Behavior of gastrin and gastric juice secretion in acute and chronic kidney failure before and after kidney transplantation].

In 50 patients (10 anephric, 10 with chronic renal failure, and 30 with acute renal failure) the correlation was studied between basal PG levels and basal and stimulated gastric acid secretion. a) The mean PG level in all 3 groups was significantly higher than in the control group, with the highest values in the anephric, which decreased to normal after kidney transplantation. b) In the patients with ARF and after transplantation there was a very positive correlation between PG levels and kidney function. c) Hemodialysis decreased PG levels moderately but significantly. d) Gastric acid studies showed in all groups a very low BAO and basal intragastric pH, with a significant release of gastric acid after pentagastrin stimulation, especially in the anephric.
