  • Title: Postprandial serum bile acids in resected and non-resected patients with Crohn's disease.
    Author: Heuman R, Sjödahl R, Tobiasson P, Tagesson C.
    Journal: Scand J Gastroenterol; 1982 Jan; 17(1):137-40. PubMed ID: 7134829.
    Abstract:
    Fasting and postprandial serum conjugates of cholic acid (CCA) and chenodeoxycholic acid (CCDA) were determined by radioimmunoassay in 46 healthy individuals and 15 patients with Crohn's disease (CD), 7 bowel-resected and 8 non-resected. All patients had normal conventional liver test results, and fasting values of CCA and CCDA were within the reference ranges. Two findings appeared: the mean postprandial increases in CCA and CCDA were both lower in CD patients than than in healthy individuals, and the postprandial increase in CCA was lower in the resected patients than in the non-resected, whereas the postprandial increase in CCDA was the same in the resected and the non-resected patients. These findings show that in CD patients, whether resected or not, the postprandial levels of bile acids are low. This could reflect a decreased absorptive capacity of bile acids in the small intestine. The finding that postprandial CCA, but not CCDA, was lower in resected than in non-resected patients may reflect different sites of CCA and CCDA absorption.
