摘要 目的:探讨慢性肾脏病患者晨尿蛋白/尿肌酐(UP/Cr)比值和24h尿蛋白定量相关性及其临床应用。方法:收集我院住院103例患者晨尿及24h尿,按24h尿蛋白0.50g界点分为非临床蛋白尿组52例和临床蛋白尿组51例,分析UP/Cr比值及24h尿蛋白定量相关性;绘制ROC曲线,分析UP/Cr比值对应24h尿蛋白0.15g、1.00g和2.00g的最佳诊断界点。结果:52例非临床蛋白尿患者UP/Cr比值与24h尿蛋白定量呈正相关(r=0.37,P<0.05),以晨尿蛋白/尿肌酐≥0.09作为24h尿蛋白≥0.15g诊断的界点,其诊断敏感度0.78,特异性0.60。51例临床蛋白尿患者,UP/Cr比值与24h尿蛋白定量呈正相关(r=0.85,P<0.01),以UP/Cr≥0.96作为24h尿蛋白≥1g诊断的界点,其诊断敏感度0.92,特异性为0.93;以UP/Cr≥1.97作为24h尿蛋白≥2g诊断的界点,其诊断敏感度0.89,特异性为0.85。结论:晨尿蛋白标本测UP/Cr比值是临床蛋白尿患者方便、可靠评估尿蛋白的方法。对于微量蛋白尿患者,需要结合分析24h尿蛋白和UP/Cr比值,以更好的评估病情。
