Abstract
The aim of the present study was to explore the relationship between plasma sphingolipids and hepatitis C virus (HCV) replication in chronic hepatitis C (CHC) patients.A cohort of 120 treatment-naïve CHC patients was included. Liver biopsies and the Scheuer scoring system were used to assess hepatic inflammatory activity. Blood biochemical indicators, HCV-RNA load, and immunological markers were also measured. Forty-four plasma sphingolipids were identified and quantified using high-performance liquid chromatography-tandem mass spectrometry.The hexosylceramide (HexCer) (d18:1/18:1) level was significantly different between patients with a low HCV load (<10 IU/mL) and a high HCV load (≥10 IU/mL), and it was positively correlated with the HCV-RNA load (r = 0.337, P = 0.001) in CHC patients. Additionally, the plasma HexCer (d18:1/18:1) level (odds ratio 1.302, 95% confidence interval 1.129-1.502) was an independent factor for a high HCV-RNA load. For patients with hepatic inflammation grade ≤2 or HCV genotype 2, HexCer (d18:1/18:1) was independently related to a high HCV-RNA load.Plasma HexCer (d18:1/18:1) might be involved in the high viral replication level in chronic HCV infection, especially for CHC patients with genotype 2.
