该ABCB1 C1236T基因变体增加了血性中风患者服用克洛皮多格雷尔的出血风险. 了解这些遗传变异可以帮助个性化抗血小板治疗.
科学领域:
- 药物基因组学 药物基因组学
- 心血管医学 心血管医学
- 神经学 神经学
背景情况:
- 克洛皮多格雷尔是一种用于缺血性中风的标准抗血小板疗法,抑制氨酸二酸 (ADP) 诱导的血小板聚合.
- 由ABCB1基因编码的P-糖蛋白 (P-gp) 影响了克洛皮多格雷尔的吸收,并可能影响治疗反应.
- ABCB1基因多态性与药物反应的个体间变异性有关.
研究的目的:
- 调查ABCB1基因多态 (C3435T和C1236T) 对缺血性中风患者的克洛皮多格雷尔反应的影响.
- 为了确定这个患者队伍中ABCB1多态的基因型频率.
主要方法:
- 一项涉及124名用克洛皮多格雷尔治疗的缺血性中风患者的横截面研究.
- 对ABCB1C3435T和C1236T多态的评估.
- 使用VerifyNow PRU测量血小板聚合以分类反应 (不响应,响应,出血风险).
主要成果:
- 12.9%的患者没有反应,49.5%的患者有反应,41.9%的患者有出血风险.
- 与其他变体相比,ABCB1 C1236T同位素野生型 (CC) 基因型显示出出血风险增加了3.76倍 (p=0.008).
- 对C3435T的基因型频率为35.9%的野生型,43.5%的异位,16.9%的变异;对于C1236T:17.8%的野生型,39.5%的异位,42.7%的变异.
结论:
- 同性异位野生型ABCB1 C1236T基因型与用克洛皮多格雷尔治疗的缺血性中风患者的出血风险增加有显著关联.
- 对于ABCB1 C1236T,最常见的基因型是同位素变体,而对于ABCB1 C3435T,则是异位素变体.
