Abstract/OtherAbstract:
No detailed data are available on hepatic clearance, postprandial release, and distribution profile of metabolically active adipokines in splanchnic blood compartments such as portal and hepatic veins. This would be a prerequisite for understanding the role of visceral adipose tissue-derived adipokines in metabolism. Adiponectin, resistin, leptin, and visfatin concentrations were measured by enzyme-linked immunosorbent assay in peripheral veins, arterial blood, hepatic veins, and portal veins in 50 patients with liver cirrhosis undergoing transjugular intrahepatic portosystemic shunt implantation, in 6 patients with normal liver function, and in fasted and fed rats. Adiponectin, leptin, resistin, and visfatin did not differ among blood compartments in normal-weight probands in the fasted state. Adiponectin and leptin levels were similar in patients with and without liver cirrhosis. Systemic visfatin levels were decreased and resistin levels were increased in liver cirrhosis. Visfatin secretion was higher from visceral than from peripheral subcutaneous adipose tissue in liver cirrhosis. There was no hepatic clearance of visfatin. Leptin secretion was higher from peripheral than from visceral adipose tissue. Leptin did not undergo hepatic clearance. Resistin and adiponectin did not differ between blood compartments in liver cirrhosis. Resistin concentrations increased upon feeding in rats, and there was an increase in the postprandial clearance of adiponectin by the liver. A postprandial increase of leptin concentrations was restricted to peripheral adipose tissue in rats. The results give insight into the dynamics of splanchnic adipokine concentrations and help critically interpret data derived from messenger RNA expression studies.
