Crit Care:低剂量心房利钠肽预防或治疗急性肾损伤

2019-02-17 xing.T 网络

由此可见,低剂量ANP可能有效预防或治疗AKI。然而,到目前为止积累的证据并不足以证明ANP的有益效果。下一步是需要通过进行多中心、高质量、大样本的随机对照试验来阐明低剂量ANP的作用。

从理论上讲,心房利钠肽(ANP),尤其是低剂量ANP,对急性肾损伤(AKI)有益。近日,危重病医学领域权威杂志Critical Care上发表了一篇研究文章,在该研究中,研究人员通过对随机对照试验(RCT)进行更新的系统评价,评估低剂量ANP是否有效预防或治疗AKI。

研究人员检索了医学文摘数据库(EMBASE)、PubMed和Cochrane中心数据库,确定了比较低剂量ANP(≤50纳克/千克/分钟)与安慰剂或常规疗法对有AKI高危个体或AKI患者作用的随机对照试验。主要结局是AKI的发生率(预防RCT),而次要结局是院内死亡率、需要肾脏替代疗法(RRT)、住院时间和重症监护病房(ICU)停留时间、低血压发生率和血清肌酐峰值水平。研究人员使用Cochrane Collaboration偏倚风险工具评估偏倚风险,并对每个感兴趣的结局使用试验顺序分析(TSA)。

共有18项RCT(16项预防和2项治疗试验)符合该分析的纳入标准。在预防RCT中,与对照组相比,低剂量ANP组的AKI发生率显著较低(相对风险[RR]=0.51; 95%置信区间[CI]=0.36-0.72; P=0.0001)。此外,低剂量ANP组在预防(RR=0.17; 95%CI=0.04-0.64; P=0.009)和治疗(RR=0.43; 95%CI=0.20-0.93; P=0.03)RCT中RRT需求也显著降低。在次要结局中,低剂量ANP与ICU和住院时间的减少有关。偏倚风险评估和TSA结果表明,RCT的样本量和质量不足以得出低剂量ANP的疗效。

由此可见,低剂量ANP可能有效预防或治疗AKI。然而,到目前为止积累的证据并不足以证明ANP的有益效果。下一步是需要通过进行多中心、高质量、大样本的随机对照试验来阐明低剂量ANP的作用。
