4项生化指标检测在多发性骨髓瘤患者早期肾伤害的诊断价值

目的探讨4项生化指标检测在多发性骨髓瘤(MM)患者早期肾脏伤害中的变化及比较。方法回顾性分析54例诊断为MM的初发病患者(MM组)和54例体检健康者(对照组),两组检测血清中的胱抑素C(Cys C)、肌酐(Cr)、β_2-微球蛋白(β_2-MG)、乳酸脱氢酶(LDH)水平,并将结果进行统计学分析。结果 MM组和对照组Cys C、Cr、β_2-MG、LDH比较差异有统计学意义(P0.05)。MM组Cys C、Cr、β_2-MG、LDH、Cys C+Cr、β_2-MG+LDH及4项联合检测阳性率分别为63.0%、42.6%、74.1%、61.1%、66.7%、85.2%和96.3%;Cys C检测阳性率高于Cr阳性率,差异有统计学意义(P0.05);β_2-MG+LDH检测阳性率高于Cys C+Cr检测结果,差异有统计学意义(P0.05);4项生化指标联合检测的阳性率最高。结论 MM患者早期肾脏伤害时,4项生化指标联合检测敏感度最高,有利于发现其早期肾脏的伤害。

Diagnosis value on four biochemical indicator detection for the early renal impairment in multiple myeloma patients

Objective To explore the changes and comparisons of the four biochemical indicator detection for the early renal im‐pairment in multiple myeloma patients .Methods The 54 patients with multiple myeloma of early onset(MM group) and 54 healthy peoples(control group) were retrospectively analyzed .The levels of serum Cystatin C(Cys C) ,creatinine(Cr) ,β2‐microglobulin(β2‐MG) ,and lactate dehydrogenase(LDH) were detected .And the results for statistical analysis .Results The levels of serum Cys C , Cr ,β2‐MG and LDH were higher significantly in the MM group than in the control group ,the difference was statistically significant (P<0 .05) .In the MM group ,the positive rate of Cys C ,Cr ,β2‐MG ,LDH ,combined detection of Cys C and Cr ,combined detection of β2‐MG and LDH ,combined detection of Cys C ,Cr ,β2‐MG and LDH was 63 .0% ,42 .6% ,74 .1% ,61 .1% ,66 .7% ,85 .2% and 96 .3% respectively .The positive rate of Cys C was higher than Cr ,the difference was statistically significant(P<0 .05) .Between the positive rate of combined detection of β2‐MG ,LDH and Cys C ,Cr ,the difference was statistically significant(P<0 .05) .The positive rate of combined detection of the four biochemical tests was the most highest .Conclusion In the early stage of the renal in‐jury in the patients with MM ,the combined detection of the four biochemical tests is most sensitive to discovery the early stage of the renal glomerular function injury .
