方法:选择42例初发多发性骨髓瘤患者和40例健康体检者,分别测定其血清Cys -C 、尿素(Urea )、肌酐(Scr )及β2-微球蛋白(β2-microglobulin ,β2-MG )水平含量。
结果:多发性骨髓瘤组血清Cys -C 和β2-MG 水平较对照组明显升高,差异有统计学意义(P <0.01);血清Scr 水平较对照组明显升高(P <0.05)。

而Ⅰ期和Ⅱ期血清Cys-C、Scr和β2-MG水平之间没有明显差别,差异无统计学意义(P>0.05)。
Cys-C与β2-MG呈正相关(r=0.474,P<0.05)。
结论:Cys-C可以作为诊断多发性骨髓瘤患者肾功能损害的敏感内源性标志之一,而且优于Urea、Scr和β2-MG,在多发性骨髓瘤分期和判断预后中也有重要的临床意义。

肾脏损害是MM常见的继发性脏器损害之一,不少患者以肾脏病变为首发,可早于其它症状1-6个月[2]。
因此MM早期肾损害的检测指标意义重大。
我们对42例初发MM患者血清胱抑素C(cystatin C,Cys-C)、尿素(Urea)血清肌酐(Scr)及β2微球蛋白(β2-microglobulin,β2-MG)进行联合检测,旨在了解MM患者血清Cys-C的水平及其与疾病临床特征的关系。
报告如下。
1资料与方法1.1资料1.1.1分组方法MM组:选择2010年6月至2012年5月在我院住院的初次诊断MM患者42例,男26例,女16例;年龄38-80岁,平均(60.3ʃ12.5)岁。
根据β2-MG及白蛋白水平进行国际分期标准(ISS)分期,其中Ⅰ期18例,Ⅱ期14例,Ⅲ期10例;IgA16例,IgG18例,轻链8例;所有病例的诊断及疗效评价均参照《血液病诊断及疗效标准》[3]。
对照组:选择同时期本院健康体检者40例,男20例,女20例;年龄40-81岁,平均(58ʃ10.3)岁。
