Abstract

Objective: To evaluate the efficacy of high and moderate doses of simvastatin (80 and 40 mg), for raising high density lipoprotein-cholesterol (HDL-C), improving HDL sub-fractions, and affecting other parameters, including high sensitivity C-reactive protein (hs-CRP), in patients with type 2 diabetes mellitus (DM) and low HDL-C. Research design and methods: This double-blind, placebo-controlled, randomized, 3-period, complete block, 6-week crossover study examined the efficacy of simvastatin in adult men and women (N = 151) with stable type 2 DM (HbA1C < 9%), low density lipoprotein-cholesterol (LDL-C) > 100 mg/dL (2.6 mmol/L), HDL-C < 40 mg/dL (< 1 mmol/L), and fasting triglyceride level > 150 (> 1.7 mmol/L) and < 700 mg/dL (< 7.9 mmol/L). This study included adult men (71%) and women (29%) of various races (89% white, 6% black, 1% Asian, 3% other) enrolled from 29 practice-based sites in the United States. Main outcome measures: Percentage change in HDL-C from baseline at the end of each 6-week treatment interval. Results: Both simvastatin 80 and 40 mg significantly increased total HDL-C from baseline (mean increases of 8% ± 1 [SE] and 5% ± 1, respectively; p < 0.001) compared with placebo, and significantly reduced plasma concentrations of LDL-C (p < 0.001), triglycerides (p < 0.001), apolipoprotein B (p < 0.001), and hs-CRP (p ≤ 0.012). Compared with simvastatin 40 mg, the 80 mg dose provided additional efficacy. Simvastatin 80 mg also significantly (p < 0.001) increased HDL2 from baseline (14% ± 3[SE]) and placebo phases (10 ± 3). An exploratory analysis showed 87% (simvastatin 80 mg) and 82% (simvastatin 40 mg) of patients reached the NCEP ATP III treatment goals for LDL-C compared with 14% on placebo. Conclusions: Both simvastatin 80 and 40 mg raise HDL-C and improve other measures associated with elevated coronary risk in patients with type 2 DM and low HDL-C.
