Abstract
Background/aims The pathogenesis of steatohepatitis remains largely unknown; however, bile acids may play a role as potential mediators of liver damage. The aim of this study was to characterize bile acid profiles in liver tissue of patients with steatohepatitis. Methods Bile acid composition was determined by gas–liquid chromatography in liver tissue from patients with nonalcoholic steatohepatitis (NASH; n=15), patients with alcoholic steatohepatitis (ASH; n=14), and controls (n=8). Liver biopsies were graded for steatosis, inflammation, and fibrosis. Results Bile acids were moderately increased in liver tissue of steatohepatitis patients compared with controls (PPPPP<0.01). Conclusion This study shows a distinct pattern of bile acids in the liver of patients with steatohepatitis. Further, the association between bile acids and histological liver injury suggests an association of specific bile acids and disease progression, possibly through bile acid-induced liver injury.Keywords
