Extralipid effects of micronized fenofibrate in dyslipidemic patients

The aim of this study was to evaluate the levels of lipid and extralipid parameters in patients with atherogenic dyslipidemia. We investigated the lipid-lowering therapeutic efficacy of fenofibrate and its extralipid influence on oxidized low-density lipoprotein (oxLDL), C-reactive protein (CRP), Fibrinogen, factor VII and plasminogen activator type 1 (PAI-1) during 1-month treatment. Fourteen individuals with HLPIIb were treated with micronized fenofibrate (267 mg/d) for 1 month. The control group included twelve volunteers. Lipidograms were determined with enzymatic kits. ELISA method was used to measure oxLDL and PAI-1. Plasma CRP levels were measured spectrophotometrically. Fibrinogen and factor VII serum levels were evaluated with automatic coagulometer. After 1-month therapy with micronized fenofibrate, we observed a significant reduction of total cholesterol (TC) (277.2 to 217.8 mg/dl, p < 0.05), LDL (183.6 to 129.4 mg/dl, p < 0.05), trigliceryde (TG) (316.7 to 220.6 mg/dl, p < 0.05), oxLDL (68.7 +/- 5.5 to 39.7 +/- 3.7 U/l, p < 0.001) and increase in high-density lipoprotein (HDL) (35.1 to 41.9 mg/dl, p < 0.05). Fibrate treatment also decreased CRP(5.81 +/- 0.26 to 5.08 +/- 0.06 mg/l, p < 0.001), PAI-1 (120.4 +/- 9.7 to 84.7 +/- 5.9 ng/ml; p < 0.05), fibrinogen (3.65 +/- 0.17 to 3.44 +/- 0.16 g/l, ns) and factor VII (159.7% +/- 56.7 to 141% +/- 42.4, ns). The micronized fenofibrate at a daily dose of 267 mg demonstrated a highly beneficial effect on all lipid parameters and advantageous influence on inflammatory and thrombogenic plasma risk factors in patients with dyslipidemia HLPIIb.
