Intens Care Med:铁状态与血行感染风险之间的关系

2018-07-25 xing.T MedSci原创

由此可见,严重铁缺乏指标与未来BSI风险增加有关。

由于铁对免疫功能和微生物生长都至关重要,因此铁状态的改变可能会影响感染风险。近日,危重病医学领域权威杂志Intensive Care Medicine上发表了一篇研究文章,研究人员评估了铁状态与血行感染(BSI)以及BSI死亡风险之间的关系。

研究人员在基于人群的HUNT2研究(1995-1997)中测量了61852名参与者的血清铁、转铁蛋白饱和度(Tsat)和总铁结合能力(TIBC);并通过与挪威中部脓毒症登记中心联系确定了BSIs的发生情况(1995-2011),该登记中心包含了来自于当地和地区医院的BSI患者前瞻性注册信息。研究人员使用Cox比例风险回归分析评估了铁状态指标与首次出现BSI和BSI死亡的风险。

在中位随访14.8年期间,1738名患者至少经历过一次BSI发作,370名患者在BSI后30天内死亡。在调整了年龄和性别的分析中,BSI风险在铁缺乏、血清铁≤第2.5百分位数(HR 为1.72,95%CI为1.34-2.21)、Tsat≤第2.5百分位数(HR为1.48,95%CI为1.12–1.96)或TIBC≥第97.5百分位数(HR为1.46,95%CI为1.06-2.01)的参与者中增加。在调整合并症和排除与癌症、风湿性疾病和炎症性肠病相关的BSI后,这些关联仍然存在。BSI死亡也得到了类似的关联。

由此可见,严重铁缺乏指标与未来BSI风险增加有关。
