Diabetes Care:RAS双重阻断改善I型糖尿病患者动脉顺应性

2012-08-07 高晓方译 医学论坛网

  加拿大学者的一项研究表明,在非复杂性I型糖尿病患者中,基于阿利吉伦的肾素-血管紧张素系统(RAS)双重阻断与更好的动脉顺应性、血流介导的舒张功能(FMD)和肾脏血管舒张有关。论文于2012年7月30日在线发表于《糖尿病护理》(Diabetes Care)杂志。   糖尿病与RAS活化相关性,并可导致肾脏和全身血管功能障碍,进而引发终末器官损害和发病率升高。利用血管紧张素转换酶抑制剂

  加拿大学者的一项研究表明,在非复杂性I型糖尿病患者中,基于阿利吉伦的肾素-血管紧张素系统(RAS)双重阻断与更好的动脉顺应性、血流介导的舒张功能(FMD)和肾脏血管舒张有关。论文于2012年7月30日在线发表于《糖尿病护理》(Diabetes Care)杂志。

  糖尿病与RAS活化相关性,并可导致肾脏和全身血管功能障碍,进而引发终末器官损害和发病率升高。利用血管紧张素转换酶抑制剂(ACEI)阻断RAS可降低但无法无安全阻断其效应。此项研究于高血糖和正常血糖钳夹情况下于基线时测定动脉硬度、FMD和肾脏血液动力学功能。在阿利吉伦治疗4周以及阿利吉伦联合雷米普利治疗4周后重复测定上述指标。

  结果显示,在高血糖和正常血糖钳夹期间阿利吉伦的降压效果相似,并且联合治疗可增强上述效果(P=0.0005)。在高血糖和正常血糖钳夹情况下阿利吉伦可降低动脉硬度,并且双重RAS阻断可增强上述效应(P=0.0001)。在正常血糖钳夹情况下阿利吉伦可升高FMD,并且双重治疗可增强上述效应(P=0.0001)。阿利吉伦单药治疗仅在高血糖钳夹期间可导致血管扩张。与之相反,双重治疗可在高血糖和正常血糖钳夹期间增强血管舒张效应。
