J Am Soc Nephrol:血液透析患者静脉注射铁剂量和感染风险之间的关系

2021-02-27 MedSci原创 MedSci原创

既往研究发现,给患者(如接受维持性血液透析的患者)静脉注射(IV)铁剂可能会增加感染的风险。主动静脉铁治疗(PIVOTAL)试验评估了给血液透析患者注射铁剂的感染率,发现高剂量和低剂量注射患者的感染率

既往研究发现,给患者(如接受维持性血液透析的患者)静脉注射(IV)铁剂可能会增加感染的风险。主动静脉铁治疗(PIVOTAL)试验评估了给血液透析患者注射铁剂的感染率,发现高剂量和低剂量注射患者的感染率相同,结果已发表于J Am Soc Nephrol。

研究将2141名因ESKD接受维持性血液透析的患者随机分为高剂量或低剂量静脉铁组。主要复合结果为全因死亡、心脏病发作、中风或因心力衰竭住院,次要终点包括感染、感染住院和感染死亡率;研究人员计算了这些终点的累积事件率;探究了铁剂量和血管通路(瘘管与导管)之间的相互作用。

 

结果显示,两组患者在所有感染的事件发生率(分别为46.5%与45.5%)和感染住院率(分别为29.6%与29.3%)上没有显著差异。首次心血管事件的发生风险与前30天内的感染之间存在显著关联。与接受动静脉瘘透析的患者相比,通过导管进行透析的患者发生任何感染、感染住院或致命感染的发生率较高,但静脉注射铁剂对这些结果没有影响。

综上所述,该研究结果表明,高剂量和低剂量静脉注射铁剂组表现出相同的感染率。首次心血管事件的风险与近期感染密切相关。
