ABSTRACT
OBJECTIVE:
To examine the effects of fenofibrate (160mg/d) therapy on fasting and postprandial cytokine production in subjects with metabolic syndrome and hypertriglyceridemia. RESEARCH DESIGN ANDMETHODS:
Randomized, double-blind, controlled trial that compared the effects of 3-month therapy with placebo and fenofibrate on fasting and postprandial cytokine production in 55 subjects with metabolic syndrome and elevated fasting triglycerides (>or=1.7 and <6.78mmol/L).RESULTS:
Fenofibrate treatment reduced concentrations of monohydroxy fatty acids (OH-FA) by 15.5% (p=0.001), lipopolysaccharide activated monocyte chemotactic protein-1 (MCP-1/CCL2) production in fasting blood samples by 3.4% (p=0.01 vs. placebo), macrophage inflammatory protein-1alpha (MIP-1alpha/CCL3) by 3.5% (p=0.01), and interleukin-1beta (IL-1beta) by 2.5% (p=0.04). After a standardized fat load (50kg/m(2)), OH-FA were reduced by 31.0% (p<0.0001), MCP-1/CCL2 was reduced by 5.2% (p=0.002), MIP-1alpha/CCL3 by 3.9% (p=0.007), and IL-1beta by 3.4% (p=0.02). Reductions in MCP-1/CCL2, MIP-1alpha/CCL3, and IL-1beta production correlated with changes in fasting and postprandial large very low-density lipoprotein (VLDL) (all p<0.005) and small low-density lipoprotein (LDL) particles (all p<0.05). In stepwise regression models that included age, gender, weight change, and drug assignment, large VLDL particles were associated with reductions in postprandial MCP-1/CCL2 (p=0.042), MIP-1alpha/CCL3 (p=0.003), and IL-1beta (p=0.02).CONCLUSIONS:
This study reports that fenofibrate reduces whole blood production of inflammatory cytokines and hepatic-synthesized inflammatory proteins, and the anti-inflammatory effects of fenofibrate therapy involve VLDL- and LDL-mediated pathways.
