摘要: [摘要] 目的 探讨 SUDOSCAN 仪评价 2 型糖尿病( type2diabetesmellitus , T2DM )患者肾脏病变的可行性
与准确性。方法 本研究共纳入 297 例 T2DM 患者,根据肾小球滤过率( estimatedglomerularfiltrationrate , eGFR )
以及尿白蛋白肌酐比( urinaryalbumintocreatinineratio ,
UACR )分为糖尿病肾功能正常组(对照组)和糖尿病肾病
(
diabetickidneydisease , DKD )组。结 果 DKD 组 患 者 血 肌 酐 ( serum creatinine , SCr )、血 尿 素 氮 ( bloodurea
nitrogen , BUN )、 UACR 高于对照组, eGFR 低于对照组( P <0.05 )。 2 组间总胆固醇( totalcholesterol , TC )、三酰
甘油(
triglyceride , TG )、低密度脂蛋白胆固醇( low-densitylipoproteincholesterol , LDL-C )以及高密度脂蛋白胆固
醇( high-densitylipoproteincholesterol ,
HDL-C )差异均无统计学意义( P >0.05 )。 DKD 组双手电化学汗液电导率
平均值( handelectrochemicalskinconductance ,
HESC )、双足电化学汗液电导率平均值( footelectrochemicalskin
conductance , FESC )以 及 糖 尿 病 肾 脏 疾 病 修 正 指 数 ( SUDOSCAN-modification ofdiabeticrenaldisease ,
SUDOSCAN-MDRD )均低于对照组,差异有统计学意义( P <0.05 )。年龄、病期、糖化血红蛋白( hemoglobinA 1 c ,
HbA 1 c )与 HESC 呈负相关, eGFR 与 HESC 呈正相关( P <0.05 )。年龄、病期、收缩压( systolicbloodpressure ,
SBP )、 HbA 1 c 与 FESC 呈负相关, eGFR 与 FESC 呈正相关( P <0.05 )。年龄、病期、 SBP 、 BUN 与 SUDOSCAN-
MDRD 呈负相关,与 eGFR 呈正相关( P <0.05 )。以 SUDOSCAN-MDRD 预测肾脏损伤明显优于其他指标,其预
测 DKD 的最佳切点为 57.
50uSi , ROC 曲线下面积为 67. 7% ,敏感度为 60. 0% ,特异度为 75.0% ,准确度为 68. 7% ,
阳性预测值为 63.6% ,阴性预测值为 72.1% 。结论 SUDOSCAN 检测指标与肾功能损伤显著相关,可辅助用于
T2DM 患者 DKD 的早期风险筛查。
