Two distinct forms of hepatocellular steatosis can be seen in patients with chronic hepatitis C virus (HCV) infection. Classical metabolic risk factors for hepatocellular steatosis account for the vast majority of cases of steatosis in patients infected by non-genotype 3 HCV strains. In contrast, in patients infected by HCV genotype 3, steatosis is generally induced by the virus itself through a direct cytopathic effect, the mechanisms of which remain debated. Mixed forms of steatosis can also be seen in HCV genotype 3-infected patients with metabolic risk factors. Hepatocellular steatosis appears to be associated with more rapid progression of hepatic fibrosis. However, it is unclear whether this association is due to steatosis itself, or rather to metabolic and host factors that promote steatosis and fibrosis concomitantly. This review discusses current knowledge of HCV-induced steatosis and its relation to chronic HCV-associated liver disease.
