[The exocrine pancreatic function in chronic renal insufficiency (author's transl)].

46 patients, who suffered from chronic renal insufficiency (serum creatinine: 1,4-14,9 mg%) and had not yet been dialysed, were given a secretin-pancreozymin-test. Statistical evaluation of the results and comparison with a healthy reference group showed amylase secretion, total secretory volume and bicarbonate secretion to be significantly reduced in patients with serum creatinine levels above 4,0 mg%. No signs of secondary hyperparathyroidism (laboratory data, osseous changes) were observed. Blood base excess and increased serum creatinine levels were significantly related. Together with influences of low protein diet metabolic acidosis going along with chronic renal insufficiency is consequently considered to be the pathogenic factor responsible for alterations in the exocrine function of the pancreas and for the occurrence of chronic pancreatitis.
