JAMA:静脉铁输注对缺铁性贫血患者低磷血症的影响

2020-02-05 MedSci MedSci原创

研究发现,对于口服铁制剂不耐受的缺铁性贫血患者,注射异麦芽糖酐铁导致的低磷血症风险显著低于羧基麦芽糖铁

静脉铁输注可快速纠正缺铁性贫血,但某些制剂可诱导成纤维细胞生长因子23介导的低磷血症。近日研究人员比较了异麦芽糖酐铁与羧基麦芽糖铁对低磷血的影响。

245名18岁以上的缺铁性贫血患者参与研究,患者血红蛋白水平≤11g/dl;血清铁蛋白水平≤100ng/ml,口服铁制剂无效或不耐受,随机在第0天接受1000mg的异麦芽糖酐铁或在第0、7天接受750mg的羧基麦芽糖铁。研究的主要终点为基线至35天低磷血症(血清磷酸盐水平<2.0mg/dl)。

A研究中,123名患者参与,平均年龄45.1岁,女性占95.9%,其中62人接受异麦芽糖酐铁,61人接受羧基麦芽糖铁,研究完成率为95.1%。B研究中,122名患者参与,平均年龄42。6岁,女性占94.1%,其中61人接受异麦芽糖酐铁,61人接受羧基麦芽糖铁,研究完成率为93.4%。异麦芽糖酐铁组相比于羧基麦芽糖铁,低磷血症发生率显著降低(A研究,7.9% vs 75.0%;B研究,8.1% vs 73.7%)。除低磷血症和甲状旁腺激素增加以外,最常见的不良事件包括恶心和头疼。

研究发现,对于口服铁制剂不耐受的缺铁性贫血患者,注射异麦芽糖酐铁导致的低磷血症风险显著低于羧基麦芽糖铁。

CFDA:关注阿德福韦酯的低磷血症及骨软化风险

国家食品药品监督管理总局(CFDA)日前发布第64期《药品不良反应信息通报》,提示关注阿德福韦酯致低磷血症及骨软化风险。 阿德福韦酯于2005年在我国上市,有片剂和胶囊两种剂型,临床上用于治疗有乙型肝炎病毒活动复制证据,并伴有血清氨基酸转移酶(ALT或AST)持续升高或肝脏组织学活动性病变的肝功能代偿的成年慢性乙型肝炎患者。国家药品不良反应监测数据库分析提示,阿德福韦酯在长期使用后可引起
