摘要 目的探讨老年血透患者促红细胞生成素(EPO)抵抗的影响因素。方法67例老年血透患者均采用皮下注射重组EPO(r-HuEPO),当血细胞比容(HCT)达到目标水平33%~36%时确定r-HuEPO的剂量,根据r-HuEPO治疗剂量进行分组,rHu EPO治疗剂量<300 IU·kg^(-1)·w^(-1)为非EPO抵抗组44例,r-HuEPO治疗剂量≥300 IU·kg^(-1)·w^(-1)为EPO抵抗组23例。对两组患者进行临床基本情况、生化、血常规、铁代谢、C反应蛋白(CRP)、甲状旁腺激素(PTH)及尿素清除指数(Kt/V)比较,并分析EPO抵抗指数(ERI)与其他各指标的相关性。结果两组临床基本情况、血清铁蛋白(SF)、转铁蛋白饱和度(TSAT)均无统计学差异(P>0.05)。EPO抵抗组血清白蛋白(ALB)、血红蛋白(HGB)、HCT、Kt/V低于非EPO抵抗组(P<0.05),CRP、PTH、ERI高于非EPO抵抗组(P<0.05)。所有老年血透患者ERI与ALB、SF、TSAT、Kt/V均呈负相关(P<0.05),ERI与CRP、PTH均呈正相关(P<0.05)。结论老年血透患者发生EPO抵抗与铁储备、营养状况、微炎症、毒素蓄积、透析充分性等多因素相关。
