Abstract/OtherAbstract:
Epidemiological studies have shown a positive association between cholesterol gallstones and colonic cancer. These two diseases may be somehow related with bile acids metabolic alterations. The aim of this study was to evaluate the profiles of fecal bile acid in gallstone patients, in order to estimate the quality and amount of fecal bile acids. A fecal bile acid profile of ten gallstone patients and ten controls was compared using high performance liquid chromatography. Total fecal bile acid excretion was significantly increased in gallstone patients compared with controls (692.7 mg/day (302.5-846.2) vs 165.7 mg/day (138.7-221.3), p < 0.01) as was the excretion of secondary free bile acids 562.9 mg/day (253.3-704.9) vs 99.9 mg/day (88.9-154.2), p < 0.01). Lithocholic and glycodeoxycholic acid percentages have also been found to show differences with controls of 55.4 (47.4-73.9) vs 24.6 (22.1-38.4) (p < 0.01) and 29.4 (3.3-41.7) vs 2.8 (1.0-3.8) (p < 0.03), respectively but deoxycholic acid has not shown differences between the two groups. Moreover, the percentage of ursodeoxycholic acid diminished significantly in gallstone patients (1.5 (1.0-2.8) vs 8.6 (6.0-10.39) (p < 0.001), and the decrease of chenodeoxycholic acid was also significant (20.0 (11.4-23.6) vs 8.9 (3.1-10.9) (p < 0.03) along with a rise in the ratios lithocholic/deoxycholic acids (1.8 (1.4-6.4) vs 0.9 (0.6-1.6) (p < 0.05) and glycine/taurine of deoxycholic acid (7.3 (4.1-46.6) vs 0.2 (0.1-0.5) (p < 0.01). In conclusion, we have observed a significant increase of total and secondary fecal bile acid excretion as well as a rise of LCA and GDCA percentages and a rise in the ratios of LCA/DCA and glycinet/taurine of DCA.
