OBJECTIVE: This study aimed to examine a novel microRNA (miR-652-3p) biomarker to improve early diagnosis of acute kidney injury (AKI) in patients with acute decompensated heart failure (ADHF) and to evaluate the survival predictive value of miR-652-3p. METHODS: We retrospectively analyzed the data of 196 patients with ADHF, including 65 who developed AKI during hospitalization. Neutrophil gelatinase-associated lipocalin (NGAL) levels were measured in serum and urine samples. Real-time quantitative PCR was applied to evaluate miR-652-3p mRNA expression. The diagnostic performance of miR-652-3p was examined using receiver operating characteristic curve analysis. The prognostic value of miR-652-3p was also analyzed. RESULTS: Serum and urinary NGAL and miR-652-3p levels were elevated in patients with ADHF and AKI. Serum and urinary miR-652-3p expression had diagnostic value in predicting AKI onset in patients with ADHF, and it had improved diagnostic performance when used with NGAL. Patients with AKI and high miR-652-3p levels had a high failure rate of renal recovery and poor 180-day survival. CONCLUSION: Serum and urinary miR-652-3p may be a candidate biomarker for early diagnosis of AKI in patients with ADHF and for predicting the prognosis of AKI. The combination of NGAL and miR-652-3p may accurately predict AKI onset in ADHF.
目的:本研究旨在检测一种新型微小RNA(miR-652-3p)生物标志物,以改善急性失代偿性心力衰竭(ADHF)患者急性肾损伤(AKI)的早期诊断,并评估miR-652-3p的生存预测价值。 方法:我们回顾性分析了196例ADHF患者的数据,其中65例在住院期间发生了AKI。检测血清和尿液样本中的中性粒细胞明胶酶相关脂质运载蛋白(NGAL)水平。应用实时定量PCR评估miR-652-3p mRNA表达。使用受试者工作特征曲线分析检测miR-652-3p的诊断性能。还分析了miR-652-3p的预后价值。 结果:ADHF合并AKI患者的血清和尿NGAL以及miR-652-3p水平升高。血清和尿miR-652-3p表达对预测ADHF患者AKI的发生具有诊断价值,与NGAL联合使用时诊断性能有所提高。AKI且miR-652-3p水平高的患者肾脏恢复失败率高,180天生存率低。 结论:血清和尿miR-652-3p可能是ADHF患者AKI早期诊断及AKI预后预测的候选生物标志物。NGAL和miR-652-3p联合使用可准确预测ADHF患者AKI的发生。
