    Abstract:
    OBJECTIVE: We examined the effects of drug therapy with pravastatin (P) or bezafibrate (B) and diet (D) therapy on serum lipids and soluble intercellular adhesion molecule-1 (sICAM-1) in hyperlipidemic cerebrovascular disease (CVD) patients in the chronic stage. METHODS: This study included 36 patients (28 with cerebral infarction and hyperlipidemia and eight with cerebral hemorrhage and hyperlipidemia) divided into three groups: Group P (12 patients), Group B (10 patients), and Group D (14 patients). Before and after treatment, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) and sICAM-1 levels were measured. RESULTS: In Group P, Group B and Group D, TC levels were decreased by 30% (p < 0.005), 21% (p < 0.01), and 21% (p < 0.001), LDL-C levels were decreased by 38% (p < 0.005), 18% (not significant), and 25% (p < 0.005) and TG levels were decreased by 27% (p < 0.05), 53% (p < 0.005) and 22% (p < 0.05), respectively. sICAM-1 levels were decreased by 20% (p < 0.005) in Group P, but were not decreased in Group B or Group D. There was no correlation between deltaTC and delta sICAM-1 (r = 0.172). CONCLUSION: Administration of pravastatin significantly reduced sICAM-1 levels, independently of its decreasing effect on TC and TG in chronic CVD patients. Pravastatin may exert anti-atherosclerotic activity via two distinct mechanisms.
