Lancet Haematology:缺铁妇女补铁方案比较研究

2017-10-10 zhangfan MedSci原创

对于缺铁女性,将每日补充的铁剂分开服用会导致血清铁调素浓度升高影响铁吸收。研究认为,将每日的补充铁剂一次性服用,隔日1次是最优的补铁方案

近日研究人员比较了连续铁剂补充和隔日铁剂补充,以及清晨单剂量补充和日两次分割剂量铁剂补充对缺铁女性铁吸收的影响。

研究招募了18-40岁的缺铁妇女,患者服用Fe54、57以及58标记的硫酸亚铁片。在试验1中,患者在早8点服用60mg铁剂,持续14天或隔日服用60mg铁剂,持续28天。在试验2中,患者在早8点服用120mg铁剂或早8点以及晚5点分别服用60mg铁剂。研究的主要终点是铁的生物利用度。

试验1中招募患者40人,其中每日组21人,隔日组19人,试验结束后,每日组铁吸收的几何平均累积分数为16.3%,隔日组为21.8%,铁累积的吸收量分别为131.0mg和175.3mg。在试验开始的前14天,每日组血清铁调素浓度高于隔日组。试验2招募了20人,每组各10人。研究发现,组间铁吸收累积分数以及总吸收量无显著差异,但日两次组患者血清铁调素浓度较高。研究中未发现3-4级严重不良事件。

研究认为,对于缺铁女性,将每日补充的铁剂分开服用会导致血清铁调素浓度升高影响铁吸收。研究认为,将每日的补充铁剂一次性服用,隔日1次是最优的补铁方案。
