Abstract

Bile acids play a leading role in the physical and colloidal properties of bile stabilization. Lack of bile acids consequences result in the formation of cholesterol stones in the gall bladder, diarrhea and steatorrhea, fat-soluble vitamins impaired absorption, and kidney stones formation (oxalates).

Investigation of altered bile composition, especially the content of bile acids, in patients with gallstone disease by means of modern analytical analysis methods (liquid chromatography with mass spectrometric detection) would complement the modern ideas about mechanisms of lithogenesis and aim efforts at prevention of stone formation in the gall bladder, that was the purpose of our work.

Materials and methods. Bile samples were tested for bile acid content using liquid chromatography with mass spectrometry. 14 samples of bile from patients with cholelithiasis were included in the main group, and control group consisted of 7 bile samples from practically healthy persons.

Results. In patients with cholelithiasis there is an increase in the content of conjugated forms of bile acids – glycolic acid in 2 times (p = 0.002), taurocholic acid in 1.57 times (p = 0.062) compared with practically healthy persons. In patients with cholelithiasis, the ratio of taurocholic to glycolic acidі content (0.95 vs. 1.27, p = 0.0179), as well as glycogenodeoxycholic to glycodeoxycholic acid (1.11 vs. 1.58, p = 0.027) is significantly less than that in practically healthy persons. In addition, one in two patients with cholelithiasis does not reveal the presence of ursodeoxycholic acid in the bile.

Conclusions. The lithogenic properties of bile are primarily caused by conjugated forms of cholic acid with glycine and taurine content violation. The ratio of taurocholic to glycolic acid content in patients with cholelithiasis is significantly lower than the similar index in practically healthy persons (0.95 vs. 1.27, p = 0.0179). The ratio of glycine conjugated bile acids content, namely glycogenodeoxycholic to glycodeoxycholic acid, in patients with cholelithiasis is also significantly lower than in practically healthy individuals (1.11 versus 1.58, p = 0.027). Ursodeoxycholic acid is not defined in bile of one in two patients with cholelithiasis (50 %), while it is absent in every seventh among practically healthy persons (14.29 %).
