AIM: In acute kidney injury (AKI) regions of the kidney are hypoxic. However, for reasons yet unknown, adaptation to hypoxia through hypoxia inducible factor (HIF) is limited. Here we studied miR-22, a potential HIF repressor, in normal kidneys, as well as in rhabdomyolysis-induced AKI, a condition where miR-22 is up-regulated. METHODS: AKI in mice was provoked by IM injection of glycerol. Tissue homogenates were processed to determine the levels of candidate RNAs and proteins, as well as global gene expression profiles...

Contrast-induced acute kidney injury (CI-AKI) is a serious complication during percutaneous coronary interventions (PCI). Currently, the diagnosis of CI-AKI relies on serum creatinine (SCr) that is however affected by several limitations potentially leading to delayed or missed diagnoses. In this study we examined the diagnostic accuracy of a "bedside" measurement of plasma Neutrophil Gelatinase-Associated Lipocalin (NGAL) in the early detection of CI-AKI in 97 patients undergoing elective PCI. The overall incidence of CI-AKI was 3%...

Acute kidney injury (AKI) is a leading cause of morbidity and mortality. Cisplatin is an effective chemotherapeutic agent whose administration is limited by nephrotoxicity. Therapies to prevent cisplatin-induced AKI are lacking. While tumor necrosis factor-α (TNF) plays a key role in the pathogenesis of cisplatin nephrotoxicity, the immune signaling pathways that trigger TNF generation in this context require elucidation. Sterile injury triggers the release and activation of both isoforms of interleukin(IL)-1, IL-1α and IL-1β, and stimulation of the interleukin-1 receptor (IL-1R1) by these ligands engages a pro-inflammatory signaling cascade that induces TNF induction...

BACKGROUND AND OBJECTIVES: The Association between preoperative Urine Neutrophil Gelatinase-associated Lipocalin (uNGAL) and interlukin-18 (uIL-18) with poor 1-year allograft function has been shown in deceased-donor kidney transplant recipients previously, and also these markers could predict 3-month allograft function. However, it is unknown whether there is any association between these postoperative biomarkers with important recipient outcomes beyond this time in live-donor transplants...

Urinary kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), and serum cystatin C (Cys C) are biomarkers of acute kidney injury (AKI). However, the efficacy of combining these indices to diagnose decompensated cirrhosis is unknown. This study involved 150 patients divided into AKI and non-AKI, and healthy individuals. Urinary KIM-1 and NGAL, serum Cys and creatine, and glomerular filtration rate (GFR) were compared based on Child-Pugh liver function class. Urinary KIM-1 and NGAL concentrations and serum Cys C levels were significantly higher in patients with AKI secondary to decompensated cirrhosis than in those with AKI not secondary to decompensated cirrhosis (p < 0...

AIM: To study the role of neutrophil gelatinase-associated lipocalin (NGAL) as a marker for extrarenal complications in patients with acute coronary syndrome (ACS). MATERIALS AND METHODS: For 110 patients with ACS on days 1-3 of hospitalization, concentrations of NGAL, serum (s-NGAL) and urinary (u-NGAL) NGAL, and N-terminal fragment of pro-B natriuretic peptide (NT-proBNP) were measured, and transthoracic echocardiography was performed. Incidence of cardiovascular complications was determined during the stay in the hospital; hemodynamic parameters (systolic and diastolic blood pressure, heart rate) were measured on admission...

Tubulointerstitial nephritis and uveitis (TINU) is a rare syndrome in which idiopathic interstitial nephritis coexists with chronic recurrent uveitis. This syndrome often represents systemic disorders such as arthralgia, rash, prolonged fever, anaemia and ocular symptoms that require medication including glucocorticoid administration. Recently, novel urinary biomarkers, such as kidney injury molecule-1, neutrophil gelatinase-associated lipocalin and liver-type fatty acid-binding protein, were shown to be associated with tubulointerstitial damage and were elevated in interstitial nephritis...

Transportable normothermic kidney perfusion for 24 hours or longer could enable viability assessment of marginal grafts, increased organ utilization and improved transplantation logistics. Eleven clinically-declined kidneys were perfused normothermically, six from donors after brain stem death (DBD, median cold ischemia time 33±36.9 hours) and five from donors after circulatory death (DCD, 36.2±38.3 hours): n=3 kidneys were perfused using Ringer's lactate to replace excreted urine volume, and n=8 using urine recirculation to maintain perfusate volume without fluid replenishment...

Hemoglobinuria is associated with kidney injury in various hemolytic pathologies. Currently, there is no treatment available and its pathophysiology is not completely understood. Here we studied the potential detrimental effects of hemoglobin (Hb) exposure to the distal nephron (DN). Involvement of the DN in Hb kidney injury was suggested by the induction of renal hepcidin synthesis (p < 0.001) in mice repeatedly injected with intravenous Hb. Moreover, the hepcidin induction was associated with a decline in urinary kidney injury markers 24p3/NGAL and KIM1, suggesting a role for hepcidin in protection against Hb kidney injury...

BACKGROUND: Helicobacter pylori (HP) affects the cardiovascular system. Our aim in this study was to evaluate, whether an infection with HP causes subclinical atherosclerosis. METHODS: We included 90 patients with dyspeptic symptoms in this study. The patients underwent an upper gastrointestinal endoscopy and biopsies were taken. The patients were grouped according to histopathologic examination, as HP infection negative (n = 21), HP infection positive (+) (n = 23), HP infection (++) (n = 22), HP infection (+++), (n = 24)...

Introduction: Diagnosis of contrast induced-nephropathy (CIN) by a classic renal biomarker such as creatinine concentration can be delayed because of various factors that can influence this marker. Changes in new biomarkers such as neutrophil-gelatinase associated lipocalin (NGAL) and cystatin C are postulated to be more sensitive for recognizing patients prone to CIN-acute kidney injury (AKI). Aim: To investigate the role of NGAL and cystatin C as early biomarkers in the diagnosis of kidney injury after cardiac catheterisation...

Neutrophil gelatinase-associated lipocalin (NGAL) is a small circulating protein that is highly modulated in a wide variety of pathological situations, making it a useful biomarker of various disease states. It is one of the best markers of acute kidney injury, as it is rapidly released after tubular damage. However, a growing body of evidence highlights an important role for NGAL beyond that of a biomarker of renal dysfunction. Indeed, numerous studies have demonstrated a role for NGAL in both cardiovascular and renal diseases...

Diabetes and its renal complications are major medical challenges worldwide. There are no effective drugs currently available for treating diabetes and diabetic kidney disease (DKD), especially in type 1 diabetes (T1D). Evidence has suggested that niclosamide ethanolamine salt (NEN) could improve diabetic symptoms in mice of type 2 diabetes (T2D). However, its role in T1D and DKD has not been studied to date. Here we report that NEN could protect against diabetes in streptozotocin (STZ) induced T1D mice. It increased serum insulin levels, corrected the unbalanced ratio of α-cells to β-cells, and induced islet morphologic changes under diabetic conditions...

Until now, it is impossible to identify a fatal traumatic brain injury (TBI) before post-mortem radiological investigations or an autopsy take place. It would be preferable to have an additional diagnostic tool like post-mortem biochemistry to get greater insight into the pathological pathways and survival times after sustaining TBI. Cerebrospinal fluid (CSF) and serum samples of 84 autopsy cases were collected from forensic autopsies with post-mortem intervals (PMI) of up to 148 h. The cases were categorized into a fatal TBI case group (n=42) and non-TBI controls (n=42)...

Introduction: The variable disease course of autosomal dominant polycystic kidney disease (ADPKD) makes it important to develop biomarkers that can predict disease progression, from a patient perspective and to select patients for renoprotective treatment. We therefore investigated whether easy-to-measure urinary biomarkers are associated with disease progression and have additional value over that of conventional risk markers. Methods: At baseline, inflammatory, glomerular, and tubular damage markers were measured in 24-hour urine collections (albumin, IgG, kidney injury molecule-1 (KIM-1), N -acetyl-β-d-glucosaminidase (NAG), β2 microglobulin (β2MG), heart-type fatty acid binding protein (HFABP), macrophage migration inhibitory factor (MIF), neutrophil gelatinase-associated lipocalin (NGAL), and monocyte chemotactic protein-1 (MCP-1)...

Renal ischemia-reperfusion injury (I/RI) remains a critical clinical situation. Several evidence revealed the potential reno-protective effects of Vitamin D and/or pioglitazone, on renal I/RI. This study addresses the possible involvement of the Wnt4/β-catenin signaling, p-S536NF-κBp65, PPARγ, Ang II/TGF-β, and ACE2 as potential effectors to vitamin D and pioglitazone-mediated renoprotective effects. Two sets of Sprague-Dawley rats (n=30 rat each), were randomized into sham, I/R, Vit D "alfacalcidol" (5ng/kg/day), pioglitazone (5mg/kg/day), and Vit D + pioglitazone groups...

Acute kidney injury (AKI) following transcatheter aortic valve implantation (TAVI) is associated with increased morbidity and mortality. The biomarkers neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), and interleukin-18 (IL-18) are predictive of AKI after cardiac surgery, but there is little data regarding these biomarkers after TAVI. We evaluated the associations between NGAL, KIM-1, and IL-18 levels and the incidence and severity of AKI and changes in serum creatinine after TAVI...

INTRODUCTION: Antimicrobial peptides (AMPs) have historically been evaluated for their role in protecting against uropathogens. However, there is mounting evidence to support their expression in noninfectious injury, with unclear meaning as to their function. It is possible that AMPs represent urothelial injury. Urinary tract obstruction is known to alter the urothelium; however, AMPs have not been evaluated for expression in this noninfectious injury. OBJECTIVE: A pilot study to compare urinary AMP expression in children undergoing surgical intervention for ureteropelvic junction obstruction (UPJO) with nonobstructed controls...
