ABSTRACT
Objective To investigate the value of cystatin CysC on early renal damage in patients with essential hypertensive.Methods Hundred-four patients who were diagnosed as essential hypertensive with microalbuminuria (Urinary microalbumin20-200 mg/L) with essential hypertensive (58 males and 46 females) were enrolled and 54 healthy subjects (30 males and 24 females) were selected as controls.Serum CysC (CysC)、Crea(Cr) 、BUNuric acid (UA) were measured and ROC curve was established based on the examination.Results There were significant difference on the level of Serum CysC[1.22(0.91,1.51 ) mg/L vs 0.73 (0.61,0.79 ) mg/L,Z=3.30,P<0.01],BUN [6.40 ( 4.43,9.06 ) mmol/L vs 5.10 ( 4.34,5.93 ) mmol/L,Z=5.94,P<0.01],Cr [96.3 (72.6,122.0 ) μmol/L vs 70.5 (56.2,76.0 ) μmol/L,Z=8.30,P<0.01],UA [375.7 ( 312.3,431.8 ) μmol/L vs 328.7 ( 271,379.3 ) mmol/L,Z=3.28,P<0.01] between essential hypertensive group and control group.According to ROC curve,the area of CysC under the ROC curve (AUC) in 104 patients was 0.87,significantly different with CR(0.78),BUN(0.66),UA(0.66) (P<0.05 or P<0.01 ) The Youden index of CysC was 0.69,and the corresponding sensitivity and specificity of CysC were 76% and 93% respectively.Conclusion The diagnostic value of serum CysC on early renal damage in patients with essential hypertensive is superior to Cr,BUN and UA,and changes of renal function can be found earlier according to the level of serum CysC,It plays a key role in the diagnosis,treatment and prognosis of the early renal damage in patients with essential hypertension.
