Abstract:
Objective To investigate the impacts of c.388A ＞ G polymorphism of the solute carrier organic anion transporter 1B1 (SLCO1B1) gene on lipid-lowering and anti-atherosclerosis effects of atorvastatin in Chinese patients with ischemic stroke.Methods The patients with ischemic stroke whose baseline low-density lipoprotein cholesterol (LDL-C) ＞ 1.8 mmol/L were enrolled prospectively.They received atorvastatin (20 mg/d) for 12 months.The lipid and bilateral carotid intima-media thickness (CIMT) were measured respectively before and after treatment.The CIMT differences between SLCO1B1 c.388A＞G genotype groups were compared.Results A total of 71 patients with ischemic stroke were enrolled,including 5 AA genotype,31 AG genotype,and 35 GG genotype.The A allele frequency was 28.9％ and the G allele frequency was 71.1％.After treatment,the total cholesterol (TC),triglyceride (TG),and LDL-C in all patients were significantly lower than those before treatment,and high-density lipoprotein cholesterol (HDL-C) was significantly increase (all P＜0.001),but CIMT did not have significant change (P=0.475).The proportion of patients whose LDL-C ＜ 1.8 mmol/L or LDL-C decreased ≥50％ in the GG genotype group was significantly higher than the AG + AA genotypes group (74.29％ vs.44.44％;x2 =6.540,P =0.011).Conclusions SLCO1B1 gene c.388A ＞ G polymorphism could influence the lipidlowering effect of atorvastatin,lipid-lowering effect in the GG genotype group was better than that in the AG+ AA genotype group.SLCO1B1 gene c.388A ＞ G polymorphism did not have effect on the antiatherosclerosis effect of atorvastatin,but it might be associated with too short follow-up time.
