Abstract
- Background & Aims Hepatitis C virus ( HCV) utilises cholesterol and lipoprotein metabolism for replication and infectivity. Statins and omega-3 (n-3) polyunsaturated fatty acids ( PUFA) have been shown to have antiviral properties in vitro. This open label pilot study evaluated the efficacy of fluvastatin (Lescol® 40-80 mg) and n-3 PUFA (Omacor®1 g and 2-4 g) on HCV- RNA and lipoviral particles ( LVP) in difficult to treat prior non-responders. Methods Patients ( n = 60) were randomly allocated in a factorial design to: no active drug; low-dose n-3 PUFA; high-dose n-3 PUFA; fluvastatin; low-dose n-3 PUFA + fluvastatin; or high-dose n-3 PUFA + fluvastatin. 50/60 completed study drugs for 12 weeks and followed up to week 24. Comparison was made between fluvastatin ( n = 24) vs no fluvastatin ( n = 26) and n-3 PUFA high-dose ( n = 17) vs low-dose ( n = 17) vs none ( n = 16). The primary outcomes were change in total HCV- RNA, LVP and ALT at week 12 compared with baseline. Secondary outcome was change in interferon-gamma-inducible protein-10 ( IP10) as a measure of interferon activation. Results 35% had compensated cirrhosis and 45% were prior null responders. There was no significant change in total HCV RNA, LVP, non-LVP or LVP ratio in patients receiving fluvastatin or n-3 PUFAs. ALT was not significantly different in those treated with fluvastatin or n-3 PUFAs. 12 weeks of low-dose n-3 PUFA decreased median IP10 concentration by −39 pg/ml (−111, 7.0 pg/ml Q1-Q3). Conclusions Fluvastatin and n-3 PUFAs have no effect on plasma HCV- RNA or LVP. The effect of low-dose n-3 PUFA on IP10 warrants further prospective evaluation as a supplemental therapy to enhance interferon sensitivity. [ABSTRACT FROM AUTHOR]
