目的  測定多發性骨髓瘤(MM)患者血清胱抑素C (Cys-C) 的水平,探討Cys-C與國際分期體系(ISS)、血β2-微球蛋白、溶骨性損害等指標的關系。 方法  收集2008年1月-2010年9月32例初治和8例復發的MM患者作為研究對象,同時收集40例健康體檢者的檢查資料作為對照組,測定血清Cys-C、血肌酐(Scr)、血β2-微球蛋白。采用核素全身骨顯像(ECT)觀察患者的溶骨性病變部位數。 結果  患者血清Cys-C水平(1.40 mg/L)明顯高于健康對照組(0.90 mg/L)(P<0.01);在MM患者中Cys-C比Scr更敏感,能反映腎小球濾過率;血清Cys-C水平與ISS分期晚,血β2-微球蛋白升高以及溶骨性病變進展密切相關。 結論  MM患者的Cys-C水平高于健康者。Cys-C是骨髓瘤腎損害的早期敏感標志物,與腫瘤負荷及溶骨性損害密切相關,可作為評價腫瘤負荷的潛在指標。
Objective  To evaluate the serum levels of cystatin-C in patients with multiple myeloma (MM), and to explore its possible correlations with clinical data, including ISS stage, serum β2-microglobulin, and advanced lytic lesions. Methods  From January 2008 to September 2010, serum cystatin-C, creatinine (Scr), and β2-microglobulin in 32 patients with MM, 8 patients with relapsed disease, and in 40 healthy controls were detected by automatic biochemistry analyzer detection. According to skeleton ECT, grading of osteolytic lesion was observed. Results  The levels of serum cystatin-C of patients with MM were significantly higher than those of the controls. Serum cystatin-C could reflect the glomerular filtration rate , and was more sensitive than Scr in patients with renal lesion. Serum cystatin-C had ber correlations with advanced ISS stages, high levels of serum β2-microglobulin, and extensive bone diseases. Conclusion  Serum cystatin-C is a sensitive marker of renal lesion in patients with MM, it could be a potential indicator to assess the tumor burden.
