Plasma secretin, pancreozymin, and somatostatin-like hormone in chronic renal failure patients.
Twenty patients with chronic renal failure (CRF) and ten patients on hemodialysis were included in the study of plasma secretin and pancreozymin measurement. Plasma somatostatin-like hormone (SLH) was measured in seven patients with CRF, eight patients in continuous ambulatory peritoneal dialysis (CAPD), and ten patients on hemodialysis. Normal subjects were used as sex- and age-matched healthy controls. Plasma secretin, pancreozymin, and SLH were determined by radioimmunoassay. Basal plasma concentration of secretin and pancreozymin was found significantly increased in hemodialysis patients in comparison to controls. Also test meal induced a significant increase of both hormones in hemodialysis patients. Basal plasma SLH was found significantly increased in both predialysis and dialysis (hemodialysis, CAPD) patients in comparison to controls. Correlation between clinical gastrointestinal disturbances and elevated hormone levels was not found. We believe that more reliable plasma measurement of these hormones will help the clinical investigation of gastrointestinal pathophysiology in uremia for the future.
