PurposeTo investigate the clinical value of urine interleukin-18 (IL-8), neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) for the early diagnosis of acute kidney injury (AKI) in patients with ureteroscopic lithotripsy (URL) related urosepsis.MethodsA retrospective study was carried out in 157 patients with urosepsis after URL. The patients were divided into AKI group and non-AKI group according to the Kidigo guideline and urine IL-8, NGAL and KIM-1 levels were detected by enzyme-linked immunosorbent assay at 0, 4, 12, 24 and 48 h after the surgery. Receiver operating characteristic curve (ROC) was used to evaluate the diagnostic value of these three biomarkers for postoperative AKI.ResultsThe level of urine IL-8, NGAL and KIM-1 in AKI group was significantly higher than that in non-AKI group at 4, 12, 24 and 48 h (p < 0.01). The ROC analysis showed the combined detection of urine IL-8, NGAL and KIM-1 at 12 h had a larger area under curve (AUC) than a single marker (0.997, 95% CI: 0.991–0.998), and the sensitivity and specificity were 98.2% and 96.7%, respectively. Pearson correlation analysis showed that the levels of urine NGAL at 4, 12, 24 and 48 h in AKI patients were positively correlated with the levels of urine KIM-1 and IL-18 (p < 0.01).ConclusionAKI could be quickly recognized by the elevated level of urine IL-8, NGAL and KIM-1 in patients with URL-related urosepsis. Combined detection of the three urine biomarkers at 12 h after surgery had a better diagnostic performance, which may be an important reference for the early diagnosis of AKI.  相似文献

Introduction

Percutaneous nephrolithotomy (PCNL) could be mentioned as the most important treatment of choice for kidney staghorn stones. Previous publications reported that the novel biomarker urinary neutrophil gelatinase-associated lipocalin (NGAL) activity significantly increases in acute kidney injury (AKI) but there is not many published articles related to increase of NGAL after PCNL procedure.

Objective

This study aimed to investigate AKI by urinary measurement of NGAL after PCNL procedure.

Subjects and methods

Based on a cross-sectional design, 41 patients with staghorn renal stones were nominated. All patients have been informed and signed the consent form. NGAL levels were measured by urinary sampling at 2 h before and 12 h after the procedure. Serum creatinines (Cr) were measured 12 h before and 48 h after the surgery. Demographic and clinical data including surgical procedure were recorded in Excel and analyzed by SPSS (SPSS Inc., Chicago, IL) for windows.

Results

With a minimum of 20 and a maximum of 70, the mean age of patients was 47 years old. 71% of patients studied were males. There was a significant change in mean serum Cr (1.06 versus 1.12 mg/dL; p < 0.01) before and after the procedure respectively. Glomerular filtration rate (GFR) with a mean of 81.93 umol/L before the procedure was decreased (p < 0.02) to 77.46 umol/L after the procedure. The changes in urine level of NGAL were significant (p < 0.02), associated to an increase in mean value of 20.63 ng/mL (two hours before) versus 56.28 ng/mL (twelve hours after)the PCNL procedure.

Conclusions

Within different extents after PCNL procedure there was a significant increase in the biomarker of NGAL levels.In order to reduce AKI and other post-operative complications, further studies in a large population of patients seem to be advantageous.  相似文献

We investigated the protective effect and mechanism of neutrophil gelatinase-associated lipocalin (NGAL) in a murine model of cisplatin-induced nephrotoxicity. Male Swiss-Webster mice were assigned to four groups (n?=?10 in each group). Control mice received vehicle only. Mice in the experimental group were given a single intraperitoneal injection of cisplatin (20?mg/kg) to induce nephrotoxicity, and were divided into three groups. The first group received 100?μL of saline only via tail vein at the time of cisplatin administration. The second group was given biologically active recombinant NGAL via tail vein (250?μg/100?μL solution). The third group was injected with a 250?μg/100μL solution of inactivated NGAL. After 4 days, we measured serum creatinine and urinary N-acetyl-β-d-glucosaminidase (NAG), and performed histologic studies. Biologically active NGAL significantly blunted the rise in serum creatinine (NGAL plus cisplatin 1.33?±?0.31 versus cisplatin alone 2.43?±?0.31?mg/dL, p?<?.001) as well as the increase in urine NAG (NGAL plus cisplatin 60.7?±?14.2 versus cisplatin alone 120.5?±?22.5 units/gm creatinine, p?<?.005). In addition, NGAL conferred a marked reduction in tubule cell necrosis and apoptosis (NGAL plus cisplatin 6.9?±?1.2 versus cisplatin alone 15.1?±?3.4 TUNEL positive nuclei per 100 cells, p?<?.001). These beneficial effects were completely abolished when heat-inactivated NGAL was administered instead of the biologically active form. Since induction of NGAL in kidney tubules is a known physiologic response to cisplatin, the pharmacologic use of NGAL to prevent cisplatin nephrotoxicity is likely to be safe and effective.  相似文献

目的脓毒症是一种临床重症疾病,严重威胁着患者的生存,合并急性肾损伤(acute kidney injury,AKI)病死率高,其治疗在临床上非常棘手。本文拟对我院采用高容量血液滤过(high volume hemofiltration,HVHF)治疗脓毒症合并AKI的病例进行回顾性分析,评价HVHF对脓毒症合并AKI的疗效。方法回顾分析我院2014年1月~2015年3月入住我院重症监护室的脓毒症合并AKI患者60例,其中男性32例,女性28例,患者年龄18~80岁。全部患者行颈内静脉或股静脉留置单针双腔导管建立血管通路,采用Baxter Accura血滤机,置换液输入剂量50 ml·kg~(-1)·h~(-1),血流量200~300 ml/min,超滤量根据患者中心静脉压、每日进出量决定。观察患者在HVHF治疗前及治疗24 h、48 h、72 h的各项指标[心率、体温、中心静脉压、平均动脉压、氧分压、血肌酐、尿素氮、血钾、血磷、血钙、碳酸氢盐、白细胞介素6(interleukin-6,IL-6)、肿瘤坏死因子α(tumor necrosis factor-α,TNF-α)]的变化,同时对HVHF治疗后第28天患者的存活情况进行分析,观察其临床转归和预后情况及是否需要继续肾脏替代治疗,并采用SPSS 17.0软件进行统计分析。结果脓毒症患者常见感染部位为肺部和消化道。治疗后第28天,60例患者中存活28例,死亡26例,其中6例需继续肾脏替代治疗,平均治疗时间为(8.56±5.32)d。HVHF治疗前、后患者体温、中心静脉压、平均动脉压、氧分压变化均无统计学差异(P0.05),心率、血尿素氮、血肌酐、血钾、血磷明显下降,差异有统计学意义(P0.05),碳酸氢盐、血钙明显上升,差异有统计学意义(P0.05)。结论 HVHF治疗能够改善脓毒症合并AKI患者的全身状态,并能够减轻肾功能损伤,提高患者生存率,对脓毒症合并AKI有较好的疗效。  相似文献

目的评价髓样细胞触发受体(triggering receptor expressed on myeloid cells,TREM)-1用于监测肝移植术后感染的价值。方法 27例肝移植术后患者按临床转归分为非感染组(11例)、感染好转组(8例)和感染非好转组(8例)。比较三组在转入ICU48h内以及感染好转组和感染非好转组感染后48h内的外周血TREM-1、肿瘤坏死因子(tumor necrosis factor,TNF)-α、乳酸水平变化。应用Pearson相关分析或Spearman等级相关分析来研究TREM-1与另两种指标的相关性,对有相关的指标利用受试者工作特征(receiver operating characteristic,ROC)曲线求出各指标的灵敏度及特异度。结果三组的TREM-1、TNF-α、乳酸组间各个时间点比较,差异均具有统计学意义(均为P〈0.05),且表达水平为感染非好转组〉感染好转组〉非感染组。感染好转组与感染非好转组的外周血TREM-1水平在发生感染前呈上升趋势,前组幅度平缓,后者升幅较大,且感染好转组外周血TREM-1水平于感染24h(高峰)后下降,而感染非好转组则持续升高。TREM-1与TNF-α、乳酸水平均呈正相关(均为P〈0.01)。三项指标之中,TREM-1灵敏度、特异度较高。结论监测转入ICU48h内的TREM-1水平可对肝移植术后患者的感染情况起到预警作用,TREM-1表达水平与肝移植术后患者感染的严重程度一致,可预测病情转归。  相似文献

Objective To investigate the risk factors of acute kidney injury (AKI) in patients after acute myocardial infarction (AMI). Methods A total of 1 371 adult patients diagnosed AMI in the First People's Hospital of Changzhou from January 2008 to December 2012 were analyzed retrospectively. AKI was defined according to the 2012 KDIGO AKI criteria. Based on the occurrence of AKI, the patients were divided into AKI group and non-AKI group. According to the AKI timing, the patients were divided into subgroups including conservative treatment groups, coronary angiography(CAG) groups and coronary artery bypass grafting (CABG) groups, respectively. Related risk factors of AKI were analyzed by univariate and multivariate logistic regression. Results Of the 1 371 patients,410(29.9%) developed AKI. Compared to the non-AKI group, in-hospital mortality increased significantly in the AKI group (17.1% vs 3.9%, χ2=68.0, P<0.001). Multifactor retrospective analysis showed that decreased baseline eGFR (OR=2.049, 95%CI: 1.246-3.370), increased fasting plasma glucose(FPG) (OR=1.070, 95%CI: 1.018-1.124), diuretics (OR=1.867, 95%CI: 1.220-2.856) and Killip class 4 status (OR=1.362, 95%CI: 1.059-3.170) were all independent risk factors of AKI, while increased DBP on admission was a protective factor (OR=0.986, 95%CI: 0.974-0.998) for the conservative management group. Decreased baseline eGFR (OR=2.371, 95%CI: 1.500-3.747), increased FPG(OR=1.009, 95%CI: 1.005-1.012), diuretics (OR=1.674, 95%CI: 1.042-2.690), intraoperative hypotension (OR=2.276, 95%CI: 1.324-3.575) and acute infection (OR=1.678, 95%CI: 1.023-2.754) were independent risk factors of AKI for the CAG group. Decreased baseline eGFR (OR=2.246, 95%CI:1.340-3.981), increased FPG (OR=1.059, 95%CI: 1.018-1.124), diuretics (OR=1.723, 95%CI: 1.122-2.650), and low cardiac output syndrome after operation (OR=2.331, 95%CI: 1.277-3.286) were independent risk factors of AKI for CABG group. Conclusions AKI is a common complication and associated with increased mortality after AMI. Decreased baseline renal function, increased FPG and diuretics were common independent risk factors of AKI after AMI.  相似文献
