ABSTRACT
<p><b>OBJECTIVE</b>To investigate the value of serum cystatin C (Cys-C), urinary Cys-C, urinary retinol binding protein (RBP) and urinary neutrophil gelatinase-associated lipocalin (NGAL) in the early assessment of multiple myeloma (MM) and their characteristic changes in different pathological types of renal impairment.</p><p><b>METHODS</b>According to glomerular filtration rate (eGFR), the patients were divided into two groups, of which marked group A with normal renal function, the other marked group B with abnormal renal function. Sixty healthy subjects were chosen as control. Detection of the serum Cys-C, urinary RBP, urinary Cys-C, urinary NGAL, serum creatinine (Scr), urinary microalbumin (MAU) and urinary α1-microglobulin (α1-MG) were performed. Renal biopsy was carried out for patients who had abnormal serum Cys-C, urinary Cys-C, urinary RBP, urinary NGAL and were willing to accept further test.</p><p><b>RESULTS</b>Compared with healthy controls, the serum Cys-C, urinary RBP, urinary Cys-C, urinary NGAL of group A were significantly higher than that of healthy controls. Six group A patients received renal biopsy, and varying degrees of renal damage were discovered. The serum Cys-C, urinary RBP, urinary Cys-C and urinary NGAL positive rate were 66.7%, 66.7%, 66.7% and 83.3%, respectively. Of twenty-four cases received biopsy after abnormal examination results were shown, six turned out to be amyloidosis, twelve cast nephropathy (CN) and 6 monoclonal immunoglobulin deposition disease (MIDD). Compared with MIDD and amyloidosis, the urinary Cys-C and NGAL of the CN group are significantly higher (P < 0.05). Compared with CN and amyloidosis, urinary RBP of MIDD is significantly higher (P = 0.043). Compared with MIDD and CN, the MAU of amyloidosis is significantly higher (P = 0.006).</p><p><b>CONCLUSION</b>Compared with the conventional indicators, serum Cys-C, urinary Cys-C, RBP and NGAL are more sensitive in early assessment of MM patients with renal damage. The MAU is higher in amyloid, the urinary Cys-C and urinary NGAL are significantly elevated in CN, the urinary RBP is significantly elevated in MIDD.</p>
