[Effect of omega-3-fatty acids on biliary lipids and lithogenicity]

Abstract

Until now no studies are available about the influences of omega-3-fatty acids on biliary lipids in men. The effects of 1.5 g omega-3-fatty acids per day on biliary lipid concentration and composition were studied in 13 male healthy persons over six weeks. Biliary cholesterol concentration decreased from 5.4 +/- 0.53 mol% to 3.7 +/- 0.30 mol% (25%) statistically significant. Phospholipids and bile acids remained unchanged. Cholesterol saturation index (CSI) was lowered from 1.13 +/- 0.12 to 0.85 +/- 0.06 (p less than 0.05). Bile acid composition and conjugation rates were unchanged. No significant side effects could be observed. Substitution of omega-3-fatty acids induced in healthy male persons a decrease of biliary cholesterol and lithogenicity.
