Abstract:
Objective To discuss the diagnostic value of serum cystatin-C(Cys-C) and urinary retinol binding protein(RBP) for the early renal impairment in multiple myeloma(MM) patients .Methods According to estimated glomerular filtration rate(eGFR) , the MM patients were divided into two groups :the normal renal function group(eGFR≥90 mL/min ,n=78)marked group A ,the renal impairment group(eGFR<90 mL/min ,n=40)marked group B .130 healthy subjects were selected as control group .The con-centrations of serum Cys-C ,urinary RBP ,serum creatinine(Cr) and serum urea nitrogen(UN) were measured and compared .Results The levels of Cys-C and RBP in group A were significantly higher than those in the control group(P<0 .01) .There were signifi-cant difference of the levels of Cys-C ,Cr ,UN and RBP levels between group B and control group(P<0 .01) .The sensitivity of the combined detection of Cys-C and RBP was 57 .69% ,significantly higher than single index test(P<0 .05) .Conclusion Compared with traditional biomarkers ,Cys-C and RBP are more sensitive and effective indexes for the diagnosis of early renal impairment in the patients with MM ,and jointed detection of the two biomarkers has important value .
