Core Tip

Core tip: Three main types of steatosis in the patients with Hepatitis C virus (HCV) infection are known: a metabolic type associated with metabolic syndrome and two viral types: one that seems to be directly triggered by the virus and one that could originate from the interference of the virus in the mechanisms of insulin resistance. The first viral type is particularly widely considered to be predominant and, perhaps, strictly linked to HCV genotype 3 infection and its intra-hepatic viral load. This evidence is supported by the resolution of steatosis in most patients infected with genotype 3 virus after HCV eradication by antiviral therapy.
