The 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor (statin)-mediated lowering of serum cholesterol has been associated with a significant reduction in cardiovascular morbidity and mortality. Recent studies suggest that additional non-lipid lowering effects (eg, endothelial stabilization, anti-inflammatory, antithrombogenic) may be important in modulating their effectiveness. Dyslipidemia is common in end-stage renal disease (ESRD), and hemodialysis patients have increased cardiovascular morbidity and mortality. Cerivastatin, a new statin with powerful low-density lipoprotein-cholesterol (LDL-C) lowering capabilities, possesses some unique non-LDL-C-mediated properties that may contribute to a reduction of coronary events in the patient with ESRD. The primary objective of this multicenter multinational study of 1,054 hemodialysis patients is to compare 2 years of treatment with cerivastatin (0.4 mg/d) versus placebo on the composite clinical event rate of myocardial infarction, sudden cardiac death, ischemic stroke, and the need for coronary arterial bypass graft (CABG) or percutaneous transluminal coronary angioplasty (PTCA) procedures in these patients. Changes in lipids, inflammatory proteins including heat stable C-reactive protein (hsCRP), interleukin-6 (IL-6), oncostatin-M, intracellular adhesion molecule-1 (ICAM-1) and monocyte-chemoattractant protein-1 (MCP-1), as well as markers of cardiac muscle pathology, such as troponin I and troponin T, will be assessed in a subset of patients. This study is the first of its kind to assess the effect of a statin on the reduction of cardiovascular morbidity and mortality in an incident hemodialysis population. It will determine whether treatment with cerivastatin can effectively reduce the significant cardiovascular morbidity and mortality.

The terminal complement complex C5b-9 is known to participate in inflammatory processes including atherosclerosis. Inflammation appears to be a direct consequence of C5b-9-mediated cell stimulation. 3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors may exert anti-inflammatory effects on vascular cells independent of lowering plasma cholesterol. Thus, we studied activation of vascular smooth muscle cells (VSMCs) by C5b-9 focusing on whether inhibition of the HMG-CoA reductase can reduce the proinflammatory effects of C5b-9.C5b-9 in sublytic concentrations increased the proliferation of human VSMCs and induced a time-dependent activation of the mitogen-activated protein (MAP) kinase extracellular signal-regulated kinase (ERK). Proliferation and ERK1/2 activation could be inhibited by the specific ERK inhibitor PD98059. HMG-CoA inhibition with cerivastatin-reduced VSMC proliferation and C5b-9-induced ERK1/2 activation. Cerivastatin also reduced the C5b-9-induced synthesis of the proinflammatory interleukin-6 (IL-6). Furthermore, C5b-9 induced activation of the transcription factors activator protein- 1 (AP-1) and nuclear factor-kappaB (NF-kappaB), which could be inhibited by pretreatment of VSMCs with cerivastatin. L-mevalonate and geranylgeranylpyrophosphate reversed the inhibitory effects of cerivastatin. The present study in VSMCs shows that cerivastatin inhibits IL-6 synthesis and cell proliferation induced by the terminal complement complex C5b-9. This may be an important mechanism contributing to the beneficial effects of HMG-CoA reductase inhibitors beyond lowering of plasma cholesterol.

The effects of cerivastatin and fenofibrate on proteins involved in haemostasis and on markers of inflammation were investigated in otherwise healthy middle-aged males with combined hyperlipidemia. Besides classical risk factors, other so-called novel risk factors for coronary artery disease are seen to be playing an increasingly important role in the development and progression of atherosclerosis. Thirty-eight males, aged 49 +/-5 years were randomised to 12 weeks treatment either with cerivastatin at a daily dose of 0.2 mg to 0.4 mg to achieve the LDL cholesterol goal of <3.0 mM, or with fenofibrate 250 mg daily. Fasting serum lipids, homocysteine, total and free tissue factor pathway inhibitor (TFPI), plasminogen activator inhibitor (PAI-1) and tissue plasminogen activator (t-PA) antigen and activity, C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were measured. No change in homocysteine level was observed in the cerivastatin group, while after fenofibrate administration it increased (p <0.0001). Total TFPI decreased significantly after cerivastatin (p = 0.002), but not after fenofibrate. Free TFPI did not decrease after either drug. Neither drug affected (t-PA) antigen and activity, while fenofibrate increased PAI-1 antigen (p <0.05) and activity (p <0.05). Cerivastatin decreased serum CRP values by 49.5% (p = 0.001), and fenofibrate by 29.8% (p = 0.03). The decreases of CRP in the two groups differed significantly (p = 0.04). IL-6 levels decreased significantly in the fenofibrate group (39%; p <0.0001), but not in the cerivastatin group (15%; p = 0.24) No significant decreases were observed for TNF-alpha. Cerivastatin had neutral effects on fibrinolysis, homocysteine or coagulation. On the other hand, fenofibrate increased PAI-1 antigen and activity and homocysteine, and did not affect coagulation. Both cerivastatin and fenofibrate reduced CRP levels, the decrease being significantly greater after cerivastatin. Fenofibrate also significantly decreased IL-6.
