We investigated the postprandial changes in plasma levels of adipocytokines in overweight patients with metabolic syndrome after an oral fat load. After an oral fat load and during a prolonged fast, blood was drawn at 0, 2, 3, 4 and 8 h for measurement of adiponectin, adipsin, cathepsin S, chemerin, hepatic growth factor, interferon-γ-inducible protein-10, leptin, macrophage chemoattractant protein-1, macrophage migration inhibitory factor, nerve growth factor, retinol binding protein-4, resistin, serum amyloid A1, tissue inhibitor of metalloproteinase-1 and thrombopoietin using a microbead-based Luminex assay. Area under the curves (AUC) were calculated and compared. Plasma adiponectin levels were higher after an oral fat load compared to fasting at t = 2 h (950 ± 513 vs. -1,881 ± 713 ng/ml) while the plasma levels for adipsin (-9 ± 5 vs. 16 ± 5 ng/ml), chemerin (-122 ± 35 vs. 13 ± 21 ng/ml), SAA-1 (-391 ± 213 vs. 522 ± 173 ng/ml) and TPO (-335 ± 144 vs. 622 ± 216 ng/ml) were lower after an oral fat load compared to fasting. The baseline corrected AUC for IP-10 was higher after fat load compared to fasting (median -116 pg h/ml; IQR -270 to 10 vs. -21 pg h/ml; IQR -136 to 418 (p = 0.047). In conclusion, in overweight male subjects with the metabolic syndrome, an oral fat load is accompanied with a modest anti-inflammatory response of adipose tissue-derived adipocytokines.
