Epidemiological studies have demonstrated an association between apolipoprotein-(apo)-B containing particles [lipoprotein (Lp) (a), LpE:B; LpC-III:B] and coronary heart disease (CHD). The effect of fluvastatin, a novel competitive inhibitor of HMG-CoA reductase, on these plasma lipoprotein levels was studied in patients with hypercholesterolaemia after 14 weeks of standard dietary therapy. The results of a placebo-controlled, dose-response study and of the combined data of the European double-blind, controlled studies on the effect of fluvastatin are presented. The patients were selected according to the following criteria of inclusion: plasma low-density-lipoprotein (LDL) cholesterol levels > 160 mg dL-1 and premature CHD and/or two associated risk factors, or LDL cholesterol > 190 mg dL-1 and no CHD, plus triglycerides < 300 mg dL-1. All measurements were performed at the Pasteur Institute Central Laboratory. Lp(a), LpE:B and LpC-III:B particles were measured by double-site ELISA. In the placebo-controlled, dose-response study, 429 subjects were randomly assigned to one of the following treatment groups: placebo, fluvastatin 2.5 mg q.p.m., 5 mg q.p.m., 10 mg q.p.m. and 20 mg q.p.m. Treatment with fluvastatin for 6 weeks was associated with a dose-dependent reduction of LDL cholesterol, apoB, LpE:B and LpCIII:B levels. In addition, treatment with fluvastatin 5 mg and 20 mg q.p.m. was associated with a significant reduction in median Lp(a) concentrations (3.2%, P < 0.05 and 6.4%, P < 0.05 respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
流行病学研究表明,含载脂蛋白(apo)-B的颗粒[脂蛋白(Lp)(a)、LpE:B;LpC-III:B]与冠心病(CHD)之间存在关联。在接受14周标准饮食治疗的高胆固醇血症患者中,研究了新型HMG-CoA还原酶竞争性抑制剂氟伐他汀对这些血浆脂蛋白水平的影响。本文展示了一项安慰剂对照、剂量反应研究的结果以及欧洲关于氟伐他汀作用的双盲对照研究的综合数据。患者根据以下纳入标准进行选择:血浆低密度脂蛋白(LDL)胆固醇水平>160mg/dL且有早发性冠心病和/或两个相关危险因素,或LDL胆固醇>190mg/dL且无冠心病,同时甘油三酯<300mg/dL。所有测量均在巴斯德研究所中央实验室进行。Lp(a)、LpE:B和LpC-III:B颗粒通过双位点ELISA进行测量。在安慰剂对照、剂量反应研究中,429名受试者被随机分配到以下治疗组之一:安慰剂、氟伐他汀2.5mg每日一次、5mg每日一次、10mg每日一次和20mg每日一次。氟伐他汀治疗6周与LDL胆固醇、apoB、LpE:B和LpCIII:B水平的剂量依赖性降低相关。此外,氟伐他汀5mg和20mg每日一次治疗与Lp(a)中位数浓度的显著降低相关(分别为3.2%,P<0.05和6.4%,P<0.05)。(摘要截短于250字)
