Clinical significance of combined detecting multiple indexes for early renal damage in patients with hy-pertension / 心血管康复医学杂志

ABSTRACT

Objective:To explore the clinical significance of combined detecting serum cystatin C (Cys-C),retinol binding protein (RBP),high sensitive C reactive protein (hsCRP)and urine microalbuminuria (UMA)for early re-nal damage detection in patients With essential hypertension (EH).Methods:Levels of Cys-C,RBP and UMA Were measured in 83 EH patients (EH group)and 80 healthy objects With similar age (healthy control group)respective-ly.Positive rates (exceeding upper limit of normal value for above index Was regarded as positive) of single and combined use of above indexes Were calculated.Results:Compared With healthy control group,there Were signifi-cant increase in levels of Cys-C [(0.98±0.30)μg/ml vs.(1.23±1.38)μg/ml],RBP [(38.32±10.10)mg/L vs. (41.67±11.68)mg/L],and UMA [(1.17±0.46)mg/L vs.(3.01±3.31)mg/L]in EH group (P<0.05 or <0.01),and their detection rates for early renal damage Were 21.69%,19.28%,14.46% and 19.28% respectively. Combined detecting rates of Cys-C + UMA and UMA+ RBP Were 36.14% and 34.94% respectively,Which Were significantly higher than those of single index (P<0.05 all).Conclusion:Proper multi-index combined detecting can effectively raise the detection rate of early renal damage in patients With hypertension.
