ABSTRACT
OBJECTIVE:
To evaluate the effect of micronised fenofibrate on serum paraoxonase (PON) and lipoprotein levels in coronary heart disease patients with type IIb hyperlipidemia. PATIENTS ANDMETHODS:
Fifty-two patients were investigated for the three-month effect of 200 mg per day micronised fenofibrate on the serum enzyme activity and concentration of PON and their relationship with serum lipids, high-density lipoprotein (HDL-C) parameters.RESULTS:
Serum paraoxonase activity was lower in CHD patients with type IIb hyperlipoproteinemia. During the three-month study it was observed that following treatment with micronised fenofibrate, serum triglyceride and cholesterol levels decreased, while HDL-C increased significantly (p<0.001). Low-density lipoprotein (p<0.05) and apolipoprotein B-100 (p<0.01) decreased, while HDL constituent apolipoprotein A-I (p<0.05) increased after micronised fenofibrate treatment. The HDL-associated paraoxonase specific activity increased significantly (p<0.05). To assess whether the increased PON activity was due to elevated HDL and apoA-I level, we standardized PON activity for HDL and apoA-I concentrations. The standardized values for HDL (PON/HDL) increased (p<0.05) while the PON/apoA-I ratio did not change significantly.CONCLUSION:
Three months of treatment with micronised fenofibrate is thought to normalize lipid profile and improve antioxidant status by increasing serum paraoxonase activity in these patients.
