AP&T: 用羧基麦芽糖铁或异麦芽糖苷铁治疗炎症性肠病患者发生低磷血症的概率分析

2019-08-10 不详 MedSci原创

缺铁和缺铁性贫血是炎症性肠病(IBD)的常见并发症。在患有中度至重度贫血,口服铁不耐受或口服铁无效的患者中,常常会使用羧基麦芽糖铁和异麦角甾醇铁进行治疗,本项研究旨在评估大剂量静脉注射铁治疗缺铁/缺铁性贫血的IBD患者发生低磷血症的概率。

背景
缺铁和缺铁性贫血是炎症性肠病(IBD)的常见并发症。在患有中度至重度贫血,口服铁不耐受或口服铁无效的患者中,常常会使用羧基麦芽糖铁和异麦角甾醇铁进行治疗,本项研究旨在评估大剂量静脉注射铁治疗缺铁/缺铁性贫血的IBD患者发生低磷血症的概率。

方法
研究人员在两个研究地点对患有铁缺乏/缺铁性贫血的成年IBD患者进行了前瞻性观察研究,其中患者接受1000mg羧基麦芽糖或铁异麦芽糖苷。在基线,第2周和第6周,收集血液粪便样品。主要终点是确定中重度低磷血症的发生率。次要终点包括低磷血症的总发病率,低磷血症的可能危险因素。

结果
本项研究共纳入了130名患者。52名患者接受了铁羧基麦芽糖,54名患者接受了铁异麦芽糖苷。与第2周的铁异麦芽糖苷相比,羧基麦芽糖治疗中重度低磷血症的发生率显着高(56.9%vs 5.7%,P  <0.001),与第2周铁异麦芽糖苷治疗相比,第6周发病率更高(13.7%vs 1.9%,P  = 0.054),羧基麦芽糖导致低磷血症的总体发生率显着高于铁异麦芽糖苷(72.5%VS11.3%,P <0.001)。

结论
在患有缺铁/缺铁性贫血的IBD患者中,与铁异麦芽糖苷相比,羧基麦芽糖铁与会导致更高的低磷血症的发生率。
