摘要
目的探讨血清胱抑素-C(Cys—C)在诊断慢性肾脏病(CKD)的意义,以及Cys-C与MDRD方程估计肾小球滤过率(GFR)的准确性及相关性。方法根据MDRD方程7计算的肾小球滤过率(GFR)将CKD患者分为5期,ELISA法检测CKD患者的Cys—C的水平,观察Cys—C与血肌酐(Scr)、GFR的相关性。结果Cys—C与Scr呈正相关,与GFR呈负相关;在肾功能轻度损伤时,Cys-C反映肾功能恶化程度的敏感度较Scr高。结论ELISA法能够检测Cys—C的水平,Cys—C能够作为反映肾功能的可靠指标,并且是肾功能的早期诊断指标。CKD2-5期,Cys—C与MDRD方程7有良好的相关性;Cys-C与MDRD方程7能够作为CKD2-5期患者估计GFR的指标。
Objective To study the clinical value of Cys-C and MDRD equation in the patient with CKD. GFR was estimated by Cys-C and MDRD equation. To study the correlation between Cys-C and MDRD e- quation. Methods According to the value of GFR of the patient with CKD, divided them into five groups. To study the correlation between Cys-C and GFR. To explore the correlation between Cys-C and Sc. Results Cys-C was correlated with Scr. There was negative correlation between Cys-C and GFR. When renal function slightly in- jured, Cys-C was higher sensitivity than Scr. Conclusion It is reliable to detect Cys-C by enzyme linked immu- nosorbent assay( ELISA). It is dependable to judge renal function by the level of Cys-C. Cys-C can be a sensitive marker to reflect GFR. GFR was estimated by Cys-C and MDRD equation. It was correlation between Cys-C and MDRD equation.
