Abstract

Hypovitaminosis D is a worldwide clinical problem, affecting populations in numerous ways. Several factors seem to affect vitamin D metabolism, including the suggestion that therapy with the lipid lowering HMG-CoA inhibitors might modulate vitamin D levels. However, the relationship between statins intake and serum levels of vitamin D is still controversial. The present work aimed to add new insights on the association between statins therapy, and more specifically the generation of statins, and the lipid profile in a population of 106 subjects treated with these HMG-CoA inhibitors. Data showed that despite a higher prevalence of hipovitaminosis D in subjects treated with statins, there is no association between statin generation, total and LDL cholesterol and vitamin D levels. Moreover, second generation statins, the most common treatment of hypercholesterolemia in the studied population, promoted the remodelling of serum fatty acids that was characterized by the increase of arachidonic acid (AA) relative levels without affecting eicosapentaenoic acid (EPA) levels. Among statin treated subjects, vitamin D levels did not affect serum fatty acid profile. The statin-related increased ratio AA/EPA suggests a pro- inflammatory status, whose long-term impact should be better clarified in the future.

通过血清脂质体图谱分析,了解他汀类药物治疗对维生素 D 缺乏症易感性的影响。
维生素 D 不足是一个世界性的临床问题,以多种方式影响着人群。影响维生素 D 代谢的因素似乎有很多,其中包括降血脂药物 HMG-CoA 抑制剂可能会调节维生素 D 水平。然而,他汀类药物摄入量与血清维生素 D 水平之间的关系仍存在争议。本研究旨在为他汀类药物治疗(更具体地说是他汀类药物的产生)与使用这些 HMG-CoA 抑制剂的 106 名受试者的血脂状况之间的关系提供新的见解。数据显示,尽管他汀类药物治疗受试者髋部维生素 D 的患病率较高,但他汀类药物的产生、总胆固醇和低密度脂蛋白胆固醇与维生素 D 水平之间并无关联。此外,第二代他汀类药物是研究人群中最常见的治疗高胆固醇血症的药物,它促进了血清脂肪酸的重塑,其特点是花生四烯酸(AA)相对水平增加,而不影响二十碳五烯酸(EPA)水平。在接受他汀类药物治疗的受试者中,维生素 D 水平不会影响血清脂肪酸谱。与他汀类药物相关的 AA/EPA 比率升高表明,他汀类药物会促进炎症状态,其长期影响应在未来得到更好的阐明。
