Objective: The benefits of fenofibrate, a peroxisome proliferator-activated receptor alpha agonist, against cardiovascular risk factors have been established. To clarify the underlying mechanisms of these benefits, we examined the effects of fenofibrate on insulin resistance, hypertension, inflammation, oxidative stress and coagulation markers in patients with metabolic syndrome. Methods: Eleven Japanese patients with metabolic syndrome underwent physical examinations and blood tests before and after treatment with fenofibrate 200 mg daily for 8 weeks. Results: Fenofibrate significantly decreased systolic blood pressure, pulse wave velocity, serum insulin, insulin resistance (calculated from the homeostasis model assessment), total cholesterol, triglyceride, remnant-like particles cholesterol, uric acid, D-dimer, fibrinogen, serum amyloid A/low-density lipoprotein (LDL) and apoA1/LDL levels. It also significantly increased levels of high molecular weight adiponectin, thrombomodulin and high-density lipoprotein cholesterol in these patients. Plasminogen activator inhibitor-1, C-reactive protein, fasting plasma glucose and thrombin-antithrombin complex levels did not change. Limitation: Small sample size. Conclusion: Short-term fenofibrate administration not only improved lipid profiles, but also ameliorated insulin resistance, hypertension and oxidative stress markers in patients with metabolic syndrome, suggesting that fenofibrate can decrease the risk of arteriosclerosis through various pathways.
