We tested the hypothesis that these adipocytokines contribute to chronic HCV-associated IR and liver injury by first comparing their serum levels and homeostasis model assessment of insulin resistance (HOMA-IR) in 154 untreated, non-diabetic, HCV-infected male subjects with fibrosis stage 0-2, to that in 75 healthy volunteers matched for age, body mass index (BMI), and waist-hip ratio (WHR). We next examined whether the adipocytokine levels were associated with the extent of hepatic steatosis, portal\/periportal inflammation and fibrosis in our total cohort of 240 HCV-infected male subjects. Significantly higher levels of HOMA-IR (2.12 versus 1.63,<\/jats:bold>\n                                 <jats:bold>\n                                    P\n                                 <\/jats:bold>\n                                 <jats:bold>= 0.01), TNF\u03b1 (1.28 versus 0.60 pg\/ml,<\/jats:bold>\n                                 <jats:bold>\n                                    P\n                                 <\/jats:bold>\n                                 <jats:bold>&lt; 0.001) and IL6 (2.42 versus 1.15 pg\/ml,<\/jats:bold>\n                                 <jats:bold>\n                                    P\n                                 <\/jats:bold>\n                                 <jats:bold>= 0.001) were noted in the HCV cohort compared with healthy controls respectively, but there were no significant differences in leptin and adiponectin concentrations. By multiple linear regression, independent predictors of HOMA-IR included the body mass index, and the serum levels of leptin (positive correlation) and adiponectin (negative correlation), but not that of TNF\u03b1 and IL6.
