Long-term therapy with hydroxymethylglutaryl coenzyme A reductase inhibitors (statins) has been shown to reduce levels of C-reactive protein (CRP). However, the generalizability, speed of onset, and dose-response characteristics of this effect are uncertain.
We measured CRP, LDL cholesterol (LDL-C), and HDL cholesterol (HDL-C) levels among 785 patients with primary hypercholesterolemia at baseline and after 8 weeks of therapy with either 0.4 or 0.8 mg of cerivastatin. Overall, cerivastatin resulted in a 13.3% reduction in median CRP levels (P:<0.001) and a 24.5% reduction in mean CRP levels (P:<0.001). Although LDL-C promptly decreased in a dose-dependent manner (mean LDL-C reduction, 37.3% for 0.4 mg and 42.2% for 0.8 mg of cerivastatin), no clear dose-response effect of cerivastatin on CRP was observed, nor was there any substantive correlation between the magnitude of change in CRP and the magnitude of change in LDL-C (r=-0.08) or the magnitude of change in HDL-C (r=-0.04). Thus, <2% of the variance in the percent change in CRP over 8 weeks could be attributed to the percent change in either of these lipid parameters. Further, there was no evidence of correlation between baseline CRP levels and baseline lipid levels or between end-of-study CRP levels and end-of-study lipid levels.
Among 785 patients with primary hypercholesterolemia, CRP levels were significantly reduced within 8 weeks of initiating cerivastatin therapy in a lipid-independent manner.
已表明羟甲基戊二酰辅酶A还原酶抑制剂(他汀类药物)的长期治疗可降低C反应蛋白(CRP)水平。然而,这种效应的普遍性、起效速度和剂量反应特征尚不确定。
我们在785例原发性高胆固醇血症患者基线时以及接受0.4或0.8mg西立伐他汀治疗8周后测量了CRP、低密度脂蛋白胆固醇(LDL-C)和高密度脂蛋白胆固醇(HDL-C)水平。总体而言,西立伐他汀使CRP中位数水平降低了13.3%(P<0.001),平均CRP水平降低了24.5%(P<0.001)。尽管LDL-C迅速以剂量依赖性方式降低(0.4mg西立伐他汀的平均LDL-C降低37.3%,0.8mg西立伐他汀的平均LDL-C降低42.2%),但未观察到西立伐他汀对CRP有明确的剂量反应效应,CRP变化幅度与LDL-C变化幅度(r=-0.08)或HDL-C变化幅度(r=-0.04)之间也无任何实质性相关性。因此,8周内CRP变化百分比中<2%的变异可归因于这些脂质参数中任何一个的变化百分比。此外,没有证据表明基线CRP水平与基线脂质水平之间或研究结束时CRP水平与研究结束时脂质水平之间存在相关性。
在785例原发性高胆固醇血症患者中,开始西立伐他汀治疗8周内,CRP水平以脂质非依赖方式显著降低。
