Ferumoxytol is a newly approved preparation of intravenous iron with a modified dextran shell that is thought to confer upon it a low immunogenic potential. Serious adverse reactions have been very uncommon in clinical studies, but these studies excluded patients with prior adverse reactions to other preparations of intravenous iron. Furthermore, the reactions were classified clinically. We report on a patient with a history of hypersensitivity to iron dextran who experienced an anaphylactic reaction after receiving ferumoxytol. Laboratory testing revealed an elevated serum tryptase level, confirming mast cell activation. This is the first laboratory-proven case of anaphylaxis related to ferumoxytol.
铁羧麦芽糖是一种新获批的静脉用铁制剂,其具有修饰的右旋糖酐外壳,被认为免疫原性较低。在临床研究中,严重不良反应非常罕见,但这些研究排除了既往对其他静脉用铁制剂有不良反应的患者。此外,这些反应是根据临床情况分类的。我们报告了一名对右旋糖酐铁过敏的患者,在接受铁羧麦芽糖后发生了过敏反应。实验室检测显示血清类胰蛋白酶水平升高,证实肥大细胞激活。这是首例经实验室证实与铁羧麦芽糖相关的过敏反应病例。
