Atherosclerosis is a result from the association of lipid deposition in the arterial wall and inflammatory process. This inflammatory process may be detected by clinical markers of systemic inflammation, such as ultrasensible C-reactive protein, which is associated with cardiovascular risk, independently of lipid levels. Statins reduce the inflammation associated to atherosclerosis, which may be verified by a reduction of the C-reactive protein levels. It seems that statins alter immune function by modulating post-translational protein prenylation. Individual genetic variations are associated with modulation of statins lipid-lowering effect; however, few studies have related the effect of the genetic variants with anti-inflammatory effect of statins. In addition to the genes involved in the cholesterol metabolism, genetic factors affecting statins pharmacodynamics and/or pharmacokinetics are potentially responsible for lipid and anti-inflammatory effects.
动脉粥样硬化是动脉壁脂质沉积与炎症过程共同作用的结果。这种炎症过程可通过全身炎症的临床标志物检测出来,比如超敏C反应蛋白,它与心血管风险相关,且独立于血脂水平。他汀类药物可减轻与动脉粥样硬化相关的炎症,这可通过C反应蛋白水平的降低得到证实。他汀类药物似乎通过调节蛋白质翻译后异戊二烯化来改变免疫功能。个体基因变异与他汀类药物降脂效果的调节有关;然而,很少有研究将基因变异的作用与他汀类药物的抗炎作用联系起来。除了参与胆固醇代谢的基因外,影响他汀类药物药效学和/或药代动力学的遗传因素可能是脂质和抗炎作用的原因。
