文摘目的:探讨2型糖尿病患者血清铁调素(Hepcidin)、铁蛋白(SF)、转铁蛋白受体(sTfR)和血清铁(SI)的变化与临床意义。方法130例2型糖尿病患者,分为两组,A 组为微量蛋白尿组45例(mAlb30-300 mg/24 h),B 组为正常蛋白尿组85例(mAlb<30 mg/24 h),另选同期45例健康体检者为对照 C 组。各组均取空腹晨血5 ml 离心取血清检测铁调素,SF,sTfR 和 SI 含量。结果A 组患者血清铁调素和 SF 水平(42.27±32.12 ng/ml,211.6±107.2 ng/ml)均显著高于B 组(26.12±18.36 ng/ml,179.1±109.7 ng/ml;P 均<0.05)和 C 组(9.47±1.65 ng/ml,84.41±47.10 ng/ml),(P 均<0.01);B 组患者铁调素和 SF 水平显著高于 C 组(P 均<0.01)。各组之间 SI 水平(15.26μmol/L,18.65μmol/L,17.71μmol/L)和 sTfR 水平(1.12μg/L,1.05μg/L,1.16μg/L)差异均无统计学意义(t =0.469-1.176,P 均>0.05)。相关分析显示,2型糖尿病患者铁调素与 SF 呈显著正相关(r=0.329,P <0.05),铁调素与 sTfR,SI 无显著相关性(r=0.169,P >0.05;r=-0.149,P >0.05)。结论2型糖尿病患者体内存在以血清铁调素、SF 增高为主的铁超负荷和铁代谢紊乱,并与尿微量清蛋白的排泄呈正相关。因此,检测血清铁调素和 SF 可作为糖尿病早期肾功能损伤的重要预测因子。
