Acute kidney injury (AKI) is defined as a syndrome in which there is an abrupt (hours to days) absolute increase in serum creatinine (SCr) of 0.5 mg/dL or a 25% increase from baseline. Even a modest rise in SCr of 0.3 mg/dL during hospitalization is associated with increased mortality and morbidity. Because of difficulties using SCr as a determinant of AKI, a variety of serum (neutrophil gelatinase–associated lipocalin, interleukin-18) and urine (kidney injury molecule–1) biomarkers of AKI are currently undergoing intense investigation. AKI may be defined pathophysiologically, as a decrease in renal blood flow (prerenal), or an intrinsic renal parenchymal disease (renal), or obstruction of urine flow (postrenal). Indications for emergent dialysis include hyperkalemia, fluid overload, acidosis, and signs and symptoms of uremia. If AKI is diagnosed in the emergency department, the patient should be admitted for further workup. In the majority of patients who survive AKI, renal function essentially returns to normal.  Key words: acute kidney injury, dialysis, hyperkalemia, serum creatinine This review contains 3 highly rendered figures, 11 tables, and 49 references.

Introduction Cisplatin-associated acute kidney injury (AKI) is the major limitation to the use of cisplatin-based chemotherapy regimens. Serum creatinine as a traditional marker did not increase in a timely enough fashion in AKI patients. Therefore, recently, the novel markers such as neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) were considered for early detection of AKI. The aim of this study was to compare the sensitivity and specificity of urinary NGAL and KIM-1 with serum creatinine in cisplatin related AKI. Methods Patients ≥18 years with solid tumors who received cisplatin-based chemotherapy were included. Urine samples were collected 0, 6 and 24 h after cisplatin infusion and the urinary NGAL, KIM-1, and creatinine concentrations were evaluated. NGAL and KIM-1 concentrations were adjusted based on urine creatinine to eliminate hydration effects. Serum creatinine levels were assessed at the base and 72 h after cisplatin administration. Results Seven out of the 35 recruited patients (20%) suffered from AKI defined by Acute Kidney Injury Network criteria. In AKI patients, the ratio of urinary KIM-1–creatinine at 24 h compared to baseline (24 h/baseline) and NGAL–creatinine 24 h/baseline were significantly higher than those of non-AKI group ( p = 0.037 and 0.047 respectively). The area under the receiver-operating characteristic curve for KIM-1–creatinine 24 h/baseline and NGAL–creatinine 24 h/baseline were 0.78 (0.59–0.96, p = 0.032) and 0.77 (0.57–0.97, p = 0.036) respectively. Conclusions Our findings showed that the changes in urinary NGAL–creatinine and KIM-1–creatinine ratios, 24 h after cisplatin administration can be utilized to predict AKI in cisplatin recipients.

Objective The aim of this study was to determine the effects of a 2-day prenatal course of indomethacin on the premature kidney as reflected by serum creatinine and urinary biomarkers. Study Design Urine of infants ≤ 32 weeks was collected for the first 14 days and analyzed for cystatin C, neutrophil gelatinase-associated lipocalin, osteopontin, β2 microglobulin, epidermal growth factor, uromodulin, and microalbumin. Bivariate analysis compared serum creatinine and biomarkers of exposed (INDO) and unexposed (CONT) subjects. Results Fifty-seven infants (35 CONT and 22 INDO) were studied. The cohorts were similar in gestational age, birthweight, race, gender, nephrotoxic medication exposure, and Apgar scores. CONT had more dopamine exposure and included more pre-eclamptic mothers (p = 0.005). No difference in creatinine-based acute kidney injury or the log transformed mean, maximum, and minimum values of urinary biomarkers was detected. Conclusion Our findings suggest that a short course of tocolytic indomethacin does not result in neonatal acute kidney injury. Key Points

Acute kidney injury (AKI) usually detected by s. creatinine, which rises after 48 hrs of insult causes delay in diagnosis and to take preventive or therapeutic measures. Hence amongst many neutrophil gelatinase associated lipocalin (NGAL) is emerging as early, sensitive, and most promising biomarker of AKI both in urine and plasma. This prospective cross sectional observational study was carried out in Combined Military Hospital (CMH) Dhaka from October 2011 to March 2012. A total of willing 100 adult patients undergoing elective coronary angiogram (CAG) with normal kidney function were included in this study. Our study defined contrast induced AKI (CI-AKI) as rise of serum creatinine by >25% or e”0.5 mg/dl from baseline after exposure to contrast media and urine NGAL e”100 ng/ml was taken as cut off value to predict AKI as calculated by ROC curve. The main outcome measures were urine NGAL at 4 hrs and serum creatinine at 48 hrs after CAG. Significant elevation of urine NGAL was noted in 9 patients after 4 hrs of CAG, of them 8 (8%) patients developed raised s. creatinine (AKI) after 48 hrs. Patient demographics and procedural factors were although statistically significant in few instances but none was predictive of AKI.J Bangladesh Coll Phys Surg 2015; 33(3): 133-139

Despite recent progress in the development of novel approaches to treat cancer, traditional antineoplastic drugs, such as cisplatin, remain a mainstay of regimens targeting solid tumors. Use of cisplatin is limited by acute kidney injury, which occurs in approximately 30% of patients. Current clinical measures, such as serum creatinine and estimated glomerular filtration rate, are inadequate in their ability to detect acute kidney injury, particularly when there is only a moderate degree of injury. Thus, there is an urgent need for improved diagnostic biomarkers to predict nephrotoxicity. There is also interest by the U.S. Food and Drug Administration to validate and implement new biomarkers to identify clinical and subclinical acute kidney injury in patients during the drug approval process. This minireview provides an overview of the current literature regarding the utility of urinary proteins (albumin, beta-2-microglobulin, N-acetyl-D-glucosaminidase, kidney injury molecule-1, neutrophil gelatinase-associated lipocalin, and cystatin C) as biomarkers for cisplatin-induced AKI. Many of the well-studied urinary proteins (KIM-1, NGAL, B2M, albumin) as well as emerging biomarkers (calbindin, monocyte chemotactic protein-1, and trefoil factor 3) display distinct patterns of time-dependent excretion after cisplatin administration. Implementation of these biomarker proteins in the oncology clinic has been hampered by a lack of validation studies. To address these issues, large head-to-head studies are needed to fully characterize time-dependent responses and establish accurate cutoff values and ranges, particularly in cancer patients. Impact statement There is growing interest in using urinary protein biomarkers to detect acute kidney injury in oncology patients prescribed the nephrotoxic anticancer drug cisplatin. We aim to synthesize and organize the existing literature on biomarkers examined clinically in patients receiving cisplatin-containing chemotherapy regimens. This minireview highlights several proteins (kidney injury molecule-1, beta-2-microglobulin, neutrophil gelatinase-associated lipocalin, calbindin, monocyte chemotactic protein-1, trefoil factor 3) with the greatest promise for detecting cisplatin-induced acute kidney injury in humans. A comprehensive review of the existing literature may aid in the design of larger studies needed to implement the clinical use of these urinary proteins as biomarkers of kidney injury.

Abstract Introduction The value of neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (Kim-1), and liver-type fatty acid binding protein (L-FABP) was assessed in early diagnosis of gentamicin-induced acute kidney injury (AKI) in dogs. Material and Methods Subcutaneous gentamicin injection in 16 healthy adult beagles made the AKI model. Blood was sampled every 6 h to detect NGAL, Kim-1, L-FABP, and serum creatinine (SCr) concentrations. Kidney tissue of two dogs was taken before the injection, as soon as SCr was elevated (78 μmol/L), and when it had risen to 1.5 times the baseline, and haematoxylin-eosin staining and transmission electron microscopy (TEM) were used to observe changes. Results NGAL, Kim-1, and SCr levels were significantly increased (P < 0.05) at 18, 30, and 78 h post injection, but L-FABP concentration was not associated with renal injury. At the earliest SCr elevation stage, findings were mild oedema, degeneration, and vacuolisation in renal tubular epithelial cells in pathology, and mild cytoplasmic and mitochondrial oedema in TEM. At this time point, NGAL and Kim-1 concentrations were significantly increased (P < 0.05), indicating that these two molecules biomark early kidney injury in dogs. Using receiver operating characteristic curve analysis, their warning levels were > 25.31 ng/mL and > 48.52 pg/mL. Conclusion Plasma NGAL and Kim-1 above warning levels are early indicators of gentamicin-induced AKI in dogs.

Background: Few studies have described associations between acute kidney injury (AKI) biomarkers, urinary neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1), and AKI in cisplatin-treated children. We aimed to describe excretion patterns of urine NGAL and KIM-1 and associations with AKI in children receiving cisplatin. Methods: Participants (n=159) were enrolled between 2013 and 2017 in a prospective cohort study conducted in 12 Canadian pediatric hospitals. Participants were evaluated at early cisplatin infusions (at first or second cisplatin cycle) and late cisplatin infusions (last or second-to-last cycle). Urine NGAL and KIM-1 were measured (1) pre-cisplatin infusion, (2) post-infusion (morning after), and (3) at hospital discharge at early and late cisplatin infusions. Primary outcome: AKI defined by serum creatinine rise within 10 days post-cisplatin based on Kidney Disease: Improving Global Outcomes guidelines criteria (≥stage 1). Results: Of 159 children, 156 (median [interquartile (IQR)] age: 5.8 [2.4-12.0] years; 78 [50%] female) had biomarker data available at early cisplatin infusions and 127 had data at late infusions. Forty-six of 156 (29%) and 22/127 (17%) developed AKI within 10 days of cisplatin administration following early and late infusions, respectively. Urine NGAL and KIM-1 concentrations were significantly higher in patients with vs. without AKI (near hospital discharge of late cisplatin infusion, median [IQR]: NGAL: 76.1 [10.0-232.7] vs. 14.9 [5.4-29.7] ng/mg creatinine; KIM-1: 4415 [2083-9077] vs. 1049 [358-3326] pg/mg creatinine; P<.01). These markers modestly discriminated for AKI (area under receiver-operating characteristic curve (AUC-ROC) range: NGAL: 0.56-0.72; KIM-1: 0.48-0.75). Biomarker concentrations were higher and better discriminated for AKI at late cisplatin infusions (AUC-ROCs range: 0.54-0.75) vs. early infusions (AUC-ROCs range: 0.48-0.65). Conclusions: Urine NGAL and KIM-1 were modest at discriminating for cisplatin-associated AKI. Further research is needed to determine clinical utility and applicability of these markers and late kidney outcomes associations.

BACKGROUND: Acute kidney injury (AKI) is a complication found in critically ill patients. Current consensus explains that diagnosis of AKI based on increased serum creatinine and decreased urine output. Neutrophil gelatinase-associated lipocalin (NGAL) level is increased a few hours after tubular damage occurred and can predict AKI more significantly than serum creatinine. Renal resistive index (RRI) is also a good marker in predicting the early stage of AKI. AIM: This study aimed to compare RRI and NGAL level as marker to predict incidence of AKI in critically ill patients treated in the Intensive Care Unit (ICU) at H. Adam Malik Hospital Medan. METHODS: This was an observational prospective cohort study and conducted in ICU at H. Adam Malik Hospital Medan in April-May 2021. This study had been approved by the Ethics Committee of Faculty of Medicine, Sumatera Utara University and H. Adam Malik Hospital Medan. Inclusion criteria are critical patients aged 18–65 years with 1st and 2nd priority level. Consecutive sampling was used. Resistive Index (RI) measured using USG Doppler by researcher and the results confirmed by ICU supervisors, while urine NGAL level measured within 3 h after ICU admission. Plasma urea and creatinine level measured after 24h after ICU admission. RESULTS: A total of 40 samples were collected; percentage of men and women are 66–35%, respectively (p = 0.001). There was a significant difference RI between AKI-group and non-AKI group (0.719 ± 0.060 and 0.060 ± 0.077, respectively) (p = 0.001). RI has a sensitivity of 71%, specificity of 84%, and accuracy of 87% in predicting occurrence of AKI with AUROC = 0.873. Meanwhile, NGAL has a sensitivity, specificity, and accuracy (66%, 89%, 78%, respectively) in early prediction of AKI incidence in critically ill patients. CONCLUSION: RI value was higher in AKI group than non-AKI group. RRI has better sensitivity than NGAL in predicting incidence of AKI.

Abstract. Background: Neutrophil gelatinase-associated lipocalin (NGAL) has been described as a potential biomarker of acute kidney injury (AKI) in different settings, but its behaviour under influence of open and endovascular repair of thoraco-abdominal aortic aneurysms (TAAA) has not been assessed yet. In this study, the course of NGAL was observed and differences of serum- (sNGAL) and urine-NGAL (uNGAL) levels following TAAA repair, especially with regard to AKI, were evaluated. Patients and methods: In this retrospective single centre study, 52 patients (mean age 64.5 years, [43–85 years]), including 39 (75 %) men, were enrolled (2014–2015, 13.2 months mean follow-up). Levels of sNGAL and uNGAL were measured perioperatively for 48 hours on intensive care unit. Twenty-three patients were treated by endovascular and 29 by open TAAA-repair. Results: Logistic regression revealed an increase in NGAL (sNGAL p = 0.0263, uNGAL p = 0.0080) corresponding with an increase in serum creatinine within the first 48 hours. Fourteen patients (26.9 %) developed AKI and 11 (21.1 %) required dialysis. The course of NGAL differed significantly (uNGAL p < .0001, sNGAL p = 0.0002) between patients suffering from AKI requiring dialysis and patients without AKI. The predictive power of uNGAL was three times higher than that of sNGAL (estimate of the regression slope 0.1382 vs. 0.0460). No significant difference between patients undergoing open or endovascular TAAA repair regarding the perioperative course of sNGAL and uNGAL was observed. Conclusion: serum-NGAL and urine-NGAL correlate with serum creatinine levels and AKI requiring dialysis. Furthermore, the postoperative course of sNGAL and uNGAL after open and endovascular TAAA repair is not significantly different. Taken together, the results indicate that uNGAL and, to a lesser extent, sNGAL could be considered biomarkers for early detection of perioperative AKI after open and endovascular TAAA surgery.
