J Antimicrob Chemother:静脉透析重症患者 输注万古霉素需要考虑透析强度?

2018年1月,发表在《J Antimicrob Chemother》上的一项前瞻性、观察性研究,在进行连续静脉-静脉血液滤过(CVVH)并接受基于剂量图的万古霉素(CIV)的患者中,考察了将CVVH强度融入到CIV剂量图中,实现CIV治疗浓度的情况。

目的:CVVH期间,获得CIV治疗浓度的最佳方法仍然未知。研究已经表明,与间歇输注相比,连续输注CIV可更快速和更一致地实现目标浓度。并发现CVVH强度和CIV清除率(CLvanc)之间存在正相关性。本研究首次在进行CVVH的患者中评估了CIV方案,其中该CVVH将基于体重的CVVH强度(mL/kg/h)融入到了剂量图中。

方法:这是一项前瞻性、观察性研究,研究对象为进行CVVH并接受基于剂量图的CIV的患者。首要结局为24小时时实现CIV治疗浓度(15~25mg/L)。次要结局为48和72小时时实现治疗浓度。

结果:分析了52例重症患者的剂量图。24小时时,43/52例患者(82.7%)实现了CIV治疗浓度。在24小时未实现治疗浓度的9例患者中,7例超过了治疗浓度,2例未达到治疗浓度。24小时时、48小时时以及72小时时的平均(SD)浓度分别为20.1(4.2)mg/L、20.7(3.7)mg/L和21.9(3.5)mg/L。与CVVH强度<20mL/kg/h的患者相比,CVVH强度>20mL/kg/h的患者在24小时时具有更高的CLvanc(3.1vs2.6L/h;P=0.013)。

结论:通过将CVVH强度融入到CIV剂量图中,多数患者在24小时实现了治疗浓度,并在48和72小时范围内维持治疗。在广泛实施之前,需要额外的研究验证该剂量图。
