摘要: 目的 探讨尿肾损伤分子-1、IL-18及血清胱抑素C联合检测对原发性肾病综合征患儿并发急性肾损伤早期的诊断价值。方法 对我院收治的153例原发性肾病综合征患儿,检测尿肾损伤分子-1、IL-18及血清胱抑素C。比较不同程度肾损伤患儿的三种指标水平,分析联合检测的诊断价值。结果 急性肾损伤组患儿(49/157,32.03%) 尿肾损伤分子-1、IL-18及血清胱抑素C水平均高于无急性肾损伤组(108/157,67.97%)(P<0.05)。不同程度急性肾损伤患儿尿肾损伤分子-1、IL-18及血清胱抑素C水平差异均具有统计学意义,且各期两两比较差异均具有统计学意义(P<0.05)。ROC曲线显示:尿肾损伤分子-1、尿IL-18、血清胱抑素C对原发性肾病综合征的患儿合并急性肾损伤诊断截断值分别为3.87μg/mL、271.04 pg/mL、1.23 mg/L ,联合诊断的AUC为0.884,其诊断效能高于单独检查(P<0.05)。结论 尿肾损伤分子-1、IL-18及血清胱抑素C均可作为原发性肾病综合征患儿并发急性肾损伤的诊断指标,联合诊断可提高诊断效能。

Abstract: Objective To explore the value of combined detection of urinary kidney injury molecule-1, interlukin-18 (IL-18) and serum cystatin C in the early diagnosis of acute kidney injury in children with primary nephrotic syndrome. Methods We enrolled 153 children with primary nephrotic syndrome and detected urinary kidney injury molecule-1, IL-18 and serum cystatin C. We compared the levels of these indicators in children with different degree of renal injury, and analyzed the diagnostic value of combined detection. Results The levels of urine kidney injury molecule-1, IL-18 and serum cystatin C in the acute kidney injury group (49/157, 32.03%) were higher than those without acute kidney injury (108/157, 67.97%) (P<0.05). The levels of urinary renal injury molecule-1, IL-18 and serum cystatin C in children with different acute kidney injury severity levels showed statistically differences (P<0.05). ROC analysis results showed that the diagnostic cut-off values of urinary kidney injury molecule-1, IL-18, and serum cystatin C in children with primary nephrotic syndrome with acute kidney injury were 3.87 μg/mL, 271.04 pg/mL and 1.23 mg/L respectively, and the AUC of combined diagnosis was 0.884, which diagnostic efficiency was higher than that of single examination (P<0.05). Conclusions Urinary kidney injury molecules-1, IL-18 and serum cystatin C can be used as diagnostic indicators for acute kidney injury in children with primary nephrotic syndrome, and combined detection can improve the diagnostic efficiency.
