摘要:

目的 探讨尿液肾损伤分子-1(KIM-1)在妊娠中期预测子痫前期患者肾损伤中的价值。方法 收集45例子痫前期患者和45名正常妊娠妇女的一般临床资料及妊娠中期(孕26~32周)的血、尿样本。采用酶联免疫吸附试验检测尿液KIM-1、中性粒细胞明胶酶相关脂质运载蛋白(NGAL),采用免疫透射比浊法检测尿液微量白蛋白(mAlb),采用碱性苦味酸法检测血清及尿液肌酐(Cr),采用酶法检测血清尿酸(UA)、尿素。采用Logistic回归分析评估子痫前期的独立危险因素。结果 子痫前期组与正常妊娠组之间孕妇年龄、样本收集时的孕周、初产妇比例及尿液mAlb、尿液NGAL、血清Cr、血清尿素水平差异均无统计学意义(P>0.05),子痫前期组孕前体重指数(BMI)及尿液KIM-1、血清UA水平明显高于正常妊娠组(P<0.05)。采用尿液Cr对尿液KIM-1、mAlb和NGAL水平进行标准化处理,子痫前期组尿液KIM-1/Cr明显高于正常妊娠组(P<0.01),而2个组之间尿液mAlb/Cr和NGAL/Cr差异均无统计学意义(P>0.05)。Logistic回归分析显示KIM-1/Cr和孕前BMI均是子痫前期的独立危险因素[比值比(OR)分别为1.38、8.48,95%可信区间(CI)分别为1.04~1.83、1.41~50.82]。结论 尿液KIM-1或许可作为妊娠中期子痫前期患者肾损伤的预测标志物。

Abstract:

Objective To study the role of urinary kidney injury molecule-1(KIM-1) determination in the prediction of pre-eclampsia kidney injury during mid-gestation. Methods A total of 45 pre-eclampsia patients and 45 healthy subjects were enrolled. Urine and serum samples and clinical data during mid-gestation (the 26th to 32nd gestational weeks) were collected. Urinary KIM-1 and neutrophil gelatinase-associated lipocalin(NGAL) were determined by enzyme-linked immunosorbent assay. Urinary microalbumin (mAlb) was determined by immune transmission turbidimetric assay. Creatine (Cr) was determined by Jaffe method,and serum uric acid (UA) and urea were determined by enzymic method. Logistic regression analysis was used to assess risk factors. Results No statistical significance was found in maternal age,gestational week at sampling,primipara ratio,urinary mAlb,urinary NGAL,serum Cr and serum urea between the 2 groups (P>0.05). The body mass index(BMI) of pre-eclampsia patients before pregnancy,urinary KIM-1 and serum UA were higher than those in healthy control group(P<0.05). After the standardization of urinary KIM-1,mAlb and NGAL according to urinary Cr,urinary KIM-1/Cr in pre-eclampsia group was higher than that in healthy control group (P<0.01),and urinary mAlb/Cr and NGAL/Cr had no statistical significance between the 2 groups (P>0.05). Logistic regression analysis showed that KIM-1/Cr and BMI before pregnancy were independent risk factors for pre-eclampsia [odds ratio (OR)=1.38 and 8.48,95% confidence interval (CI) 1.04-1.83 and 1.41-50.82]. Conclusions Urinary KIM-1 might be a potential biomarker in predicting pre-eclampsia kidney injury during mid-gestation.
