The aim of this study was to compare moderate- versus high-intensity statin therapy in patients with type 2 diabetes and low-density lipoprotein (LDL) cholesterol less than 130 mg/dL.
This was a randomized, open-label, parallel design trial comprised of 79 patients randomly allocated into two groups receiving high-intensity [atorvastatin 40 mg (A40) or rosuvastatin 20 mg (R20) daily] or moderate-intensity [atorvastatin 20 mg (A20) or rosuvastatin 10 (R10) mg daily] statins for eight weeks. The variables investigated were lipid profile, high sensitivity C-reactive protein (hs-CRP), and interleukin-6 (IL-6).
The percentage of decrease in LDL levels (±SD) for the high-intensity group (-35.5±25.5) was significantly greater than the moderate-intensity group (-24.6±23.5) (=0.04). While 38.1% (n:8) of patients receiving A20 and 55% (n:11) of those being on R10 achieved the targets of≥30% reduction in the LDL level, these figures were 63.2% (n=12) and 73.8% (n=14) for A40 and R20 subgroups, respectively. Subsequently, the likelihood of achieving LDL reduction≥30%, was significantly greater with high-intensity statin therapy (OR: 3.1, 95% CI: 1.09, 8.90, =0.03). Logistic regression analysis also showed that for every 1 mg/ dL increase in the baseline LDL level, the odds of achieving the LDL reduction≥30% increased by 1.04 times [95% CI: (1.01, 1.07), =0.003].
Despite the general conception, moderate-intensity statins are not adequate for the majority of patients with T2DM and mild hyperlipidemia and greater numbers of patients could reach the LDL cholesterol target with high-intensity statin therapy.
本研究旨在比较 2 型糖尿病患者中 LDL 胆固醇<130mg/dL 时中强度与高强度他汀类药物治疗。
这是一项随机、开放标签、平行设计的试验,共纳入 79 例患者,随机分为两组,分别接受高强度阿托伐他汀 40mg(A40)或瑞舒伐他汀 20mg(R20)每日治疗或中强度阿托伐他汀 20mg(A20)或瑞舒伐他汀 10mg(R10)每日治疗,疗程 8 周。研究变量包括血脂谱、高敏 C 反应蛋白(hs-CRP)和白细胞介素 6(IL-6)。
高强度组 LDL 水平降低率(±SD)为-35.5±25.5%,明显大于中强度组-24.6±23.5%(=0.04)。A20 组有 38.1%(n:8)患者和 R10 组有 55%(n:11)患者达到 LDL 水平降低≥30%的目标,而 A40 组和 R20 组分别为 63.2%(n:12)和 73.8%(n:14)。因此,高强度他汀类药物治疗 LDL 降低≥30%的可能性显著增加(OR:3.1,95%CI:1.09,8.90,=0.03)。Logistic 回归分析还表明,基线 LDL 水平每增加 1mg/dL,达到 LDL 降低≥30%的几率增加 1.04 倍[95%CI:(1.01,1.07),=0.003]。
尽管一般认为,中强度他汀类药物不能满足大多数 2 型糖尿病和轻度血脂异常患者的需要,更多患者可以通过高强度他汀类药物治疗达到 LDL 胆固醇目标。
