目的探讨非贫血人群血清铁蛋白(serum ferritin,SF)和转铁蛋白饱和度(transferrin saturation,TSAT)与全因死亡和心血管死亡的相关性。方法选取1999—2000年和2001—2002年国家健康和营养检查调查研究(national health and nutrition ex...目的探讨非贫血人群血清铁蛋白(serum ferritin,SF)和转铁蛋白饱和度(transferrin saturation,TSAT)与全因死亡和心血管死亡的相关性。方法选取1999—2000年和2001—2002年国家健康和营养检查调查研究(national health and nutrition examination survey,NHANES)的非贫血人群7167例,于2006年12月31日前对死亡终点进行随访,采用阈值效应分析和多因素cox回归模型分析SF和TAST与全因死亡和心血管死亡风险的相关性。结果7167例患者中男3533例、女3634例,年龄18~85岁,平均(46.1±20.0)岁,BMI平均(27.9±6.2)kg/m2。平均随访(5.1±1.2)年,共随访11623人/年,其中全因死亡452例、心血管死亡117例。SF与全因死亡和心血管死亡呈非线性相关,SF的截断值为200 ng/ml;当SF<200 ng/ml时,SF每增加100 ng/ml,全因死亡风险增加25%(HR=1.252,95%CI:1.068~1.486,P=0.008),心血管死亡风险增加37%(HR=1.370,95%CI:1.076~1.900,P=0.036)。TSAT与全因死亡率呈L型非线性相关,截断值为30%,当TSAT<30%时,TSAT每增加10%,全因死亡风险降低21%(HR=0.791,95%CI:0.681~0.914,P=0.001);TSAT与心血管死亡风险呈线性负相关(HR=0.803,95%CI:0.660~0.963,P=0.014)。结论非贫血人群的SF与全因死亡和心血管死亡呈非线性相关、截断值为200 ng/ml,TSAT与全因死亡呈L型相关、截断值为30%,且TSAT与心血管死亡呈负相关。建议将非贫血人群的SF与TSAT控制在合适范围,以降低死亡风险,并改善预后。展开更多

文摘目的探究妊娠期贫血孕妇血清铁(serum iron,SI)及可溶性血清转铁蛋白受体(soluble serum transferrin receptor,sTfR)检测与妊娠结局的关系及临床意义。方法选取2020年1月至2021年6月同济大学附属第一妇婴保健院收治的1000例孕妇作为研究对象,根据有无贫血分为贫血组(n=195)和无贫血组(n=805),比较两组孕妇的一般资料、SI、sTfR水平。随访至妊娠结束,比较两组孕妇不良妊娠结局发生情况。比较不同妊娠结局贫血孕妇的SI、sTfR水平,采用受试者操作特征(receiver operating characteristic,ROC)曲线和曲线下面积(area under the curve,AUC)评估SI、sTfR水平对贫血孕妇妊娠结局的预测价值。统计学方法采用独立样本t检验和χ^(2)检验。结果妊娠期贫血的发生率为19.50%(195/1000)。贫血组孕妇SI水平低于无贫血组[(5.5±1.0)与(18.2±6.0)μmol/L,t=29.370,P<0.001];sTfR水平高于无贫血组[(3.8±1.3)与(1.9±0.6)mg/L,t=31.638,P<0.001]。贫血组孕妇不良妊娠结局总发生率高于无贫血组[23.59%(46/195)与4.10%(33/805),χ^(2)=81.957,P<0.05]。发生与未发生不良妊娠结局贫血孕妇的SI水平分别为[(4.6±0.8)与(5.7±0.8)μmol/L,t=15.366,P<0.001],发生较未发生不良妊娠结局贫血孕妇低;sTfR水平分别为[(4.6±1.2)与(3.6±1.0)mg/L,t=8.985,P<0.001],发生较未发生不良妊娠结局贫血孕妇高。SI、sTfR单独预测的AUC分别为0.743、0.770,联合预测的AUC最大,为0.924,最佳诊断敏感度、特异性分别为80.43%、87.92%。结论SI、sTfR水平变化与妊娠期贫血的发生密切相关,联合检测对于妊娠期贫血孕妇的妊娠结局具有较高预测价值,可作为临床早期评估预测的辅助指标。
