Abstract

血友病作为常见的性联遗传性疾病广泛存在于世界的每个角落,其对病人的威胁在于反复关节肌肉出血致残及严重出血致死。血友病患者由于凝血因子缺乏需要终身进行因子替代治疗。现代血友病治疗理念已从按需替代治疗模式转变为预防治疗模式。预防治疗被公认为重型血友病患者的标准治疗方法,提倡在有条件的地方尽早开始预防治疗。其目的在于使病人有维持健康生活状态的机会,预防严重出血事件和骨关节病变的发生。但昂贵的治疗费用和频繁的静脉穿刺严重阻碍了其临床应用。近期研究发现,凝血因子在不同患者体内的药代动力学(PK)以及不同患者的出血类型存在明显差异,提出了个体化预防治疗的概念。PK指导的个体化预防治疗综合评估了血友病A患者的出血表型、凝血因子的PK、活动水平、依从性及治疗成本等,为患者制定了相对完善的个体化治疗方案,从而减少出血次数,提高生活质量。
