NGAL和血清胱抑素C在预测妊高征肾脏损伤中的诊断价值

目的研究NGAL和血清胱抑素C在预测妊娠高血压疾病肾脏损伤中的诊断价值.方法选取妊娠高血压疾病患者100例作为实验组,另选取同期住院且妊娠结局正常的孕妇50例作为对照组.入院24 h内及产后72h后检测两组血清NGAL和血清胱抑素C水平,并进行比较.结果入院24 h内,实验组患者血NGAL水平、血Cys-C水平显著高于对照组,两组比较差异具有统计学意义(t=2.256,P0.05).产后72 h后,实验组患者血NGAL水平、血Cys-C水平与对照组比较差异无统计学意义(t=0.479,P0.05).实验组各亚组间血清NGAL水平比较差异均具有统计学意义(P0.05),妊娠期高血压组Cys-C与子痫亚组比较差异具有统计学意义(P0.05),其余均未见统计学意义(P0.05).使用ROC曲线评价NGAL,Cys-C的诊断价值,其中,NGAL的ROC曲线下面积值为0.841,表明NGAL诊断准确率较高;Cys-C的ROC曲线下面积为0.810,表明Cys-C诊断准确中等,NGAL诊断准确率高于Cys-C.结论 NGAL及Cys-C可作为预测妊娠高血压疾病早期肾脏损伤的指标,可在疾病早期检测妊娠期妇女肾功能情况,及早发现,及早治疗,可有效降低孕妇和围产儿死亡,提高母婴素质,值得临床推广应用.

Diagnostic Value of NGAL and Serum Cystatin C in Predicting Hypertensive Disease of Pregnancy Renal Injury

Objective To investigate the diagnostic value of NGAL and serum cystatin C in predicting hypertensive disease of pregnancy renal injury. Method 100 patients with hypertensive disorder complicating pregnancy as the experimental group,select the same period admitted in our hospital and pregnancy outcome of normal pregnant women 50 cases as the control group. Detection of two serum NGAL and serum cystatin C levels within 24 h after admission and pregnancy after 72 h. Results Within 24 hours after admission,the experimental group in patients with serum NGAL levels,which was significantly higher than that in the control group,the two groups compared with statistical significance. Patients in the experimental group serum Cys-C levels was significantly higher than that in the control group, the two groups compared with statistical significance ( t=2. 256,P<0. 05),and in the control group compared to the difference had no statistical significance;with serum Cys-C levels in the experimental group,and the control group phase differences in the ratio was no statistically significant (t=0. 479,P<0. 05) pregnancy after 72 h,the experimental group in patients with serum NGAL levels. In the experimental group, gestational hypertension group serum NGAL level;mild preeclampsia group serum NGAL level;preeclampsia the subgroup of serum NGAL;preeclampsia serum NGAL subgroup;statistical analysis results showed that the difference was statistically significant in experimental group of each subgroup between the serum level of NGAL ( P<0 . 05 ) , with statistical significance of gestational hypertension and preeclampsia Cys-C subgroup differences (P<0. 05),there were no statistical differences (P>0. 05). Using the diagnostic value of ROC curve in the evaluation of NGAL and Cys-C. Among them,the area under the ROC curve of NGAL value is 0. 841,showed that NGAL is high diagnostic accuracy rate,Cys-C under the ROC curve area of 0. 810,showed that Cys-C diagnosis accurate medium,NGAL diagnosis accurate rate is higher than that of Cys-C. Conclusion NGAL and cystatin C may be as a predictor of pregnancy hypertension disease early renal damage index,in the disease early detection of pregnancy women with stage renal function, early detection of early treatment,can effectively reduce the maternal and perinatal mortality,improve maternal and child quality,worthy of clinical promotion.
