Twenty patients with exocrine pancreatic insufficiency secondary to alcohol abuse were studied for the presence of bile salt malabsorption. Fecal bile salts and fecal fat excretion were determined in 15 patients receiving pancreatic enzyme therapy, not receiving enzyme therapy, and on a regimen of pancreatic enzymes plus cimetidine. Serum bile salt levels were measured during fasting and postprandial conditions both during enzyme therapy and after it was stopped in 8 cases. In addition, 5 patients underwent [14Clcholylglycine breath testing during and after discontinuation of enzyme therapy. The fecal bile salt excretion varied between 610 and 3460 mg/day in the untreated patients. Treatment with pancreatic enzymes was associated with significant (p < 0.05) reduction in fecal bile salt and fecal fat excretion. Cimetidine therapy in addition to enzyme therapy further reduced steatorrhea but failed to alter bile salt excretion significantly. Serum cholylglycine level showed significant (p < 0.05) postprandial increase in patients receiving enzyme therapy, suggesting improved bile salt absorption. These data suggest a wide range of bile salt malabsorption in alcoholic patients with pancreatic insufficiency, which improves with pancreatic enzyme therapy.
