title: Bile acid malabsorption as a cause of hypocholesterolemia seen in patients with chronic pancreatitis.
abstract: A determination of caloric consumption based on a dietary survey table, fat and cholesterol intake, and analyses of fecal fatty acids and neutral sterols, and bile acid analysis (gas chromatographic method) were conducted on 33 subjects (including 17 patients with chronic pancreatitis and 16 normal controls). The factors related to hypocholesterolemia in chronic pancreatitis (CP) patients were investigated and the following conclusions were obtained: (1) The total caloric intake and fat consumption by the CP patients were significantly lower with the exception of cholesterol consumption. (2) Significant increases were noted in fecal fat, neutral sterols, and bile acid excretion by the CP patients. (3) A significant positive correlation was noted between the total cholesterol and body mass index (BMI), reaffirming that the cholesterol level can be used as an indicator of nutritional status. (4) A significant negative correlation was noted between the serum total cholesterol and fecal bile acid excretion. These findings indicate that CP patients suffer from neutral sterol malabsorption, in addition to dietary fat maldigestion and bile acid malabsorption. Furthermore, bile acid malabsorption is cited as a factor in the development of hypocholesterolemia in CP patients.
