The Effects of High Dose Pravastatin and Low DosePravastatin and Ezetimibe Combination Therapy on Lipid,Glucose Metabolism and Inflammation
Necati Dagli,1,2 Mustafa Yavuzkir,1 and Ilgin Karaca1
Objective. Coronary artery disease (CAD) is presently the major cause of mortality and morbidity. Anti-hyperlipidemic treatment is one of the main treatment steps in the management of CAD. Statins are thecornerstones in this treatment. Ezetimibe can be reliably used, when statins prove ineffective in treatment,or to reduce their side effects. In the present study we examined the effects of high-dose pravastatin (40 mg)and low-dose pravastatin (10 mg) + ezetimibe (10 mg) combination therapy on lipid and glucose mechanism,as well as inflammation.
Methods. This study registered 100 cases. Of the cases, 50 [57.1 T 11.1 years (24 (48%) females and 26(52%) males)] were administered 40 mg/day pravastatin (group 1) and 50 [53.2 T 12.2 years (27 (54%)females and 23 (46%) males)] were administered 10 mg pravastatin + 10 mg ezetimibe (group 2).
Results. In group 1, total cholesterol fell from 231.1 T 83.5 mg/dl to 211.3 T 37.2 mg/dl (p = 0.03), triglyceridefrom 243.5 T 96.8 mg/dl to 190.9 T 55.2 mg/dl (p = 0.003), and LDL cholesterol from 165.7 T 29.7 mg/dl to133.4 T 26.6 mg/dl (p = 0.02). In group 2, total cholesterol dropped from 250.9 T 51.8 mg/dl to 187.9 T 34.9mg/dl (p = 0.001), triglyceride from 270.3 T 158.9 mg/dl to 154.6 T 60.7 mg/dl (p = 0.001), and LDLcholesterol from 158.1 T 47.5 mg/dl to 116.9 T 26.4 mg/dl (p = 0.001). Insulin resistance decreased from4.05 T 2.31 to 3.16 T 1.90 (p=0.07) in group 1 and from 2.96 T 1.50 to 2.05 T 0.55 (p=0.009) in group 2. High sensitive C-reactive protein fell from 6.69 T 6.11 mg/l to 3.02 T 1.70 mg/l (p=0.01) in group 1 and from6.36 T 2.06 mg/l to 2.68 T 1.69 mg/l (p=0.001) in group 2. Conclusion. Both therapy regimes are effective. However, we found that low-dose pravastatin and ezetimibecombination therapy is more effective than high-dose pravastatin therapy on lipid metabolism, glucose metab-olism and inflammation.
