2018年1月,发表于《Nephrol Dial Transplant》的一项有西班牙和德国科学家进行的研究,考察了血液透析患者铁剂量与住院率和死亡率之间的相关性。

背景:静脉铁管理在血液透析患者中常见。然而,就住院和死亡风险来说,最安全的剂量策略仍未确定。研究者旨在确定每月累积铁剂量对死亡率和住院率的影响。

方法:这项多中心观察性回顾性倾向得分匹配研究纳入了1679例血透患者。研究者测量了基线人口统计学变量、血透临床参数和实验室分析值。研究者比较了四分位的累积铁剂量(mg/kg/月)的结局。研究者实施了倾向得分匹配(PSM)来减少适应证混杂。PSM队列中(330例患者),比较了累积铁剂量高于5.66mg/kg/月和低于5.66mg/kg/月的结局。

结果:Kaplan-Meier分析表明,高铁剂量组比低铁剂量组具有显着更差的生存期。单变量分析显示,每月铁剂量可显着预测死亡率。然而,多变量回归并未证实该结果。多变量回归分析显示,铁剂量>5.58mg/kg/月与死亡风险增加不相关,但是与全因和心血管相关住院风险增加相关。这些结果在PSM人群中得到认证。

结论:静脉铁给药适宜维持血透患者的血红蛋白水平。数据提示,调整了体重后,每月较高的铁剂量与更多的住院相关,但是与死亡或感染相关住院不相关。
