Abstract
To study pancreatic protein and water secretion in 28 patients with cystic fibrosis and 21 controls matched for pancreatic acinar function as defined by trypsin secretion, we used a quantitative-marker perfusion technique and continuous intravenous secretin-pancreozymin stimulation. Regardless of the level of pancreatic acinar function, secretions from the patients contained significantly higher concentrations of protein than those from the controls. Total protein output and albumin:protein ratios were not increased in secretions from the patients, but their fluid secretion was significantly decreased at any level of pancreatic function. A significant linear correlation was found between protein and volume secretion in the patients (r = 0.86, P<0.001), most of whom had a fluid output of less than 4.2 ml per kilogram of body weight per hour. No such relation was found in the control subjects, whose flow was always above 4.2 ml per kilogram per hour.Keywords
