Am J Kidney Dis:脓毒症伴AKI患者,是选择常规流速还是高流速的CVVHDF?

2016-10-05 xing.T MedSci原创

高流速CVVHDF治疗不能改善患者的预后,尽管其可以显著降低炎性细胞因子水平。但是CRRT治疗引起的免疫调节作用可能不足以影响临床预后。

可溶性炎症介质都是加剧败血症引起急性肾损伤(AKI)的主要因素,连续性肾脏替代治疗(CRRT)已被推荐用于去除细胞因子而发挥免疫调节功能。然而,连续静脉-静脉血液透析滤过(CVVHDF)的流速对炎症因子去除及对患者预后的影响尚未明确。


近日,肾脏病领域权威杂志《Am J Kidney Dis》上发表了韩国延世大学医学院内科Jung Tak Park及其研究团队的一篇文章,旨在探究不同流速的CVVHDF与患者炎症因子去除及预后之间的关系。

该研究为前瞻性、随机、对照、开放的试验,纳入的参与者为212例脓毒症伴AKI患者,平均年龄为62.1岁,138例(65.1%)为男性,均接受CVVHDF治疗AKI。将参与者随机分为两组,一组接受常规流速(40mL/kg/h)的CVVHDF,另一组接受高流速(80 mL/kg/h)的CVVHDF,常规流速和高流速组平均干预持续时间分别为5.4和6.2天;分别在28和90天,评估患者和肾脏存活率以及检测循环细胞因子水平。

研究者发现:常规流速组和高流速组在28天的死亡率(危险比为1.02;95%可信区间为0.73-1.43;P=0.9)或28天肾存活率(危险比为0.96;95%可信区间为0.48-1.93;P=0.9)无显著差异。相比于常规流速组,高流速CVVHDF可显著降低白细胞介素6(IL-6)、IL-8、IL-1β和IL-10水平。常规流速组和高流速组之间发生电解质紊乱情况没有显着差异。

高流速CVVHDF治疗不能改善患者的预后,尽管其可以显著降低炎性细胞因子水平。但是CRRT治疗引起的免疫调节作用可能不足以影响临床预后。
