摘      要：Hepatitis C virus (HCV) is one of the main causes of liver disease *** steatosis is a common finding in many hepatic and extrahepatic disorders,the most common being metabolic syndrome (MS).Overtime,it has been shown that the frequent coexistence of these two conditions is not coincidental,since many epidemiological,clinical,and experimental studies have indicated HCV to be strongly associated with liver steatosis and numerous metabolic ***,we present an overview of publications that provide clinical evidence of the metabolic effects of HCV and summarize the available data on the pathogenetic mechanisms of this *** has been shown that HCV infection can induce insulin resistance (IR) in the liver and peripheral tissues through multiple *** research has suggested that HCV interferes with insulin signaling both directly and indirectly,inducing the production of several proinflammatory *** replication,assembly,and release from hepatocytes require close interactions with lipid droplets and host *** modulation of lipid metabolism in host cells can induce hepatic steatosis,which is more pronounced in patients with HCV genotype *** risk of steatosis depends on several viral factors (including genotype,viral load,and gene mutations) and host features (visceral obesity,type 2 diabetes mellitus,genetic predisposition,medication use,and alcohol consumption).HCV-related IR and steatosis have been shown to have a remarkable clinical impact on the prognosis of HCV infection and quality of life,due to their association with resistance to antiviral therapy,progression of hepatic fibrosis,and development of hepatocellular ***,HCV-induced IR,oxidative stress,and changes in lipid and iron metabolism lead to glucose intolerance,arterial hypertension,hyperuricemia,and atherosclerosis,resulting in increased cardiovascular mortality.
