Hepatic fatty acid (FA) composition may influence steatosis development in patients with chronic hepatitis C (CHC). In a cross-sectional study, we compared the hepatic FA profile in hepatitis C patients with (n = 9) and without (n = 33) steatosis ( 5% of hepatocytes involved). FA composition of hepatic and RBC total lipids was measured by gas chromatography. Lipid peroxidation and antioxidants in liver and plasma, blood biochemistry, and nutritional status were also assessed. Patients with steatosis had more fibrosis, higher necroinflammatory activity of their hepatitis C infection, were more often infected with genotype 3, and had lower serum cholesterol. Monounsaturated FA in the liver were higher and trans FA were lower in patients with steatosis. Lower stearic acid and higher oleic acid in hepatic total lipids suggested higher 9-desaturase activity. -Linolenic acid in the liver was higher and the ratios of long-chain PUFA:essential FA precursors were lower for (n-3) and (n-6) PUFA. Plasma vitamin C was lower in steatosis, but RBC FA composition and other parameters did not differ. We conclude that hepatic FA composition is altered in patients with hepatitis C and steatosis, probably due to modulation of enzymatic elongation and desaturation. Oxidative stress or nutritional status does not seem to play a predominant role for development of steatosis in CHC.
