Background.: Meta-analyses failed to demonstrate clinical benefits of beta lactam plus aminoglycoside combination therapy, compared to beta lactam monotherapy, in patients with sepsis. However, few data exist on the effects of short-course adjunctive aminoglycoside therapy in sepsis patients with organ failure or shock. Methods.: We prospectively enrolled consecutive patients with severe sepsis or septic shock in two intensive care units in the Netherlands from 2011 to 2015...

BACKGROUND: The optimal timing for initiating renal replacement therapy (RRT) in patients with acute kidney injury (AKI) remains controversial. METHODS: We conducted a meta-analysis with trial sequential analysis (TSA) of randomized controlled trials (RCTs) using PUBMED, Cochrane Library databases, and Web of Science (from January 1, 1985, to August 21, 2016). Adult patients with AKI who received RRT with different timing were included. The primary outcome was mortality...

BACKGROUND Astragaloside IV (AS-IV) has been shown to prevent ischemia-induced acute kidney injury (AKI) in rat models of ischemia and reperfusion. However, the effects of AS-IV on AKI during sepsis and endotoxinemia is unclear. The current study aimed to investigate the effects and molecular mechanisms of AS-IV on lipopolysaccharide (LPS)-induced AKI. MATERIAL AND METHODS Adult male CD-1 mice were randomly assigned into 6 groups (n=8/group): control group: mice were intraperitoneally (i.p.) injected with normal saline; LPS group (10 mg/kg, i...

Background: Dialysis-dependent acute kidney injury (AKI) can be treated using continuous (CRRT) or intermittent renal replacement therapies (IRRT). Although some studies suggest that CRRT may have advantages over IRRT, study findings are inconsistent. This study assessed differences between CRRT and IRRT regarding important clinical outcomes (such as mortality and renal recovery) and cost-effectiveness. Additionally, ethical aspects that are linked to renal replacement therapies in the intensive care setting are considered...

Hypovolemia is known to be a predisposing factor of decompression illness (DCI) while diving. The typical clinically impressive neurological symptoms of DCI may distract from other symptoms such as an incipient hypovolemic shock. We report the case of a 61-year-old male Caucasian, who presented with an increasing central and peripheral neural failure syndrome and massive hypovolemia after two risky dives. Computed tomography (CT) scans of the chest and Magnetic resonance imaging scans of the head revealed multiple cerebral and pulmonary thromboembolisms...

Lipids encompass a large variety of molecules representing a highly efficient energy resource and forming structural components of membranes or signaling molecules that regulate diverse cellular events underlying not only physiological homeostatic processes but also undesirable pathogenic outcomes. The relationship between lipid disturbances and renal diseases has been studied for several decades, and it is well-recognized that when the balance of renal lipid uptake, synthesis, oxidation and outflow is disrupted, lipids will undergo oxidation, be sequestrated as lipid droplets, generate toxic metabolites and cause nephrotoxicity in diverse renal diseases...

Acute kidney injury (AKI) is characterized by an increasing incidence and poor outcomes in both developed and undeveloped countries. AKI is also acquiring importance in the setting of kidney transplantation (KT): besides all the classical forms of AKI that KT patients may undergo, several transplant-specific injuries can also lead to the loss of graft function. The mechanisms of tissue damage in native and grafted kidneys share several common pathogenic elements. Since appropriate therapeutic treatments are still lacking-probably due to the disease complexity-clinicians are forced to provide only supportive care...

The aim of the present study is to investigate whether or not bromobenzene (BB) toxicity varies with circadian periodicity. Seven-week-old male ICR mice were injected with 900 mg/kg (5.73 mmol/kg) BB intraperitoneally at 4 different time points of a day (zeitgeber time [ZT]: ZT0, ZT6, ZT12, and ZT18). Mortality was then monitored for 7 days after injection. Interestingly, mice were sensitive to BB acute toxicity at ZT6 while tolerant at ZT18. Moreover, in mice that were given a non-lethal dose of BB (540 mg (3...

Acute kidney injury induced by ischemia/reperfusion (IR) is a frequent complication in hospitalized patients. Mineralocorticoid receptor antagonism has shown to be helpful against renal IR consequences; however, the potential benefit of novel nonsteroidal mineralocorticoid receptor antagonists such as finerenone has to be further explored. In this study, we evaluated the efficacy of finerenone to prevent the acute and chronic consequences of ischemic acute kidney injury. For the acute study (24 hours), 18 rats were divided into sham, bilateral renal ischemia of 25 minutes, and rats that received 3 doses of finerenone at 48, 24, and 1 hour before the ischemia...

BACKGROUND: Delta neutrophil index (DNI), representing an elevated fraction of circulating immature granulocytes in acute infection, has been reported as a useful marker for predicting mortality in patients with sepsis. The aim of this study was to evaluate the prognostic value of DNI in predicting mortality in septic acute kidney injury (S-AKI) patients treated with continuous renal replacement therapy (CRRT). METHOD: This is a retrospective analysis of consecutively CRRT treated patients...

OBJECTIVE: Renal replacement therapy (RRT) is the treatment of choice for severe acute kidney injury, but there are no firm guidelines as to the time of initiation of RRT in the critically ill. The primary objective of this study is to determine 1-month mortality rates of early versus late dialysis in critical care. As secondary end points, we provide a cost analysis of early versus late RRT initiation, intensive care unit (ICU) length of stay (LOS), hospital LOS, and number of patients on dialysis at day 60 postrandomization...

BACKGROUND: Puumala virus (PUUV)-induced hemorrhagic fever with renal syndrome is common in many European countries. The typical renal histologic lesion is acute tubulointerstitial nephritis. We examined the type and kinetics of urine protein excretion and prognostic significance of proteinuria for the severity of acute kidney injury (AKI) in acute PUUV infection. METHODS: The amount of dipstick albuminuria at hospital admission was analyzed in 205 patients with acute PUUV infection...

RATIONALE: Sepsis-induced acute kidney injury (AKI) is a common condition with high morbidity and mortality. Neutrophil-derived heparin-binding protein (HBP) induces vascular leakage and is a promising biomarker of sepsis-induced organ dysfunction. It remains unknown if HBP is prognostic of AKI in septic shock and if HBP could play a role in the pathophysiology of sepsis-induced AKI. OBJECTIVES: To determine the association of plasma HBP levels with development of AKI, investigate the role of HBP in the pathophysiology of sepsis-induced AKI, and test the effect of blocking HBP using heparin derivatives...

PURPOSE: The purpose was to characterize acute kidney injury (AKI) in C57BL/6 (B6)- and 129/Sv (Sv)-mice by noninvasive measurement of renal perfusion and tissue edema using functional MRI. METHODS: Different severities of AKI were induced in B6- and Sv-mice by renal ischemia reperfusion injury (IRI). Unilateral clamping of the renal pedicle for 35 min (moderate AKI) or 45 min (severe AKI) was done. MRI (7-Tesla) was performed 1, 7 and 28 days after surgery using a flow alternating inversion recovery (FAIR) arterial spin labeling (ASL) sequence...

BACKGROUND: Despite multiple therapeutic approaches for nephrogenic systemic fibrosis (NSF), no single treatment has convincingly shown consistent benefit. The most successful outcomes have been associated with recovery of renal function, although evidence remains limited and past studies have been inconclusive. OBJECTIVE: We sought to investigate whether improvement of renal function via successful transplantation or via return of renal function after acute kidney injury correlates with improvement of NSF, and to further characterize the clinical features and progression of NSF...

Vascular adhesion protein-1 (VAP-1) is a unique molecule since it acts as an adhesion molecule as well as an ectoenzyme catalyzing oxidative deamination of primary amines and generates hydrogen peroxide in the extracellular space. While VAP-1 is implicated in various inflammatory diseases, its role in acute kidney injury is less characterized. Here we studied VAP-1 expression in the kidney and the effect of its inhibition in a rat model of renal ischemia/reperfusion injury. VAP-1 was predominantly expressed in pericytes, which released enzymatically active enzyme...

Cisplatin is an effective chemotherapeutic agent and widely used in treatment of various solid organ malignancies, including head and neck, ovarian, and testicular cancers. However, the induction of acute kidney injury (AKI) is one of its main side effects. Leukotriene B4 receptor 1 (BLT1) mediates the majority of physiological effects of leukotriene B4 (LTB4), a potent lipid chemoattractant generated at inflammation sites, but the role of the LTB4-BLT1 axis in cisplatin-induced AKI remains unknown. Here we found upregulated LTB4 synthesis and BLT1 expression in the kidney after cisplatin administration...

Although dialysis has been used in the care of patients with acute kidney injury (AKI) for over 50 years, very little is known about the potential benefits of uremic control on systemic complications of AKI. Since the mortality of AKI requiring renal replacement therapy (RRT) is greater than half in the intensive care unit, a better understanding of the potential of RRT to improve outcomes is urgently needed. Therefore, we sought to develop a technically feasible and reproducible model of RRT in a mouse model of AKI...

BACKGROUND: Sepsis is associated with decreased levels of high-density lipoprotein (HDL) cholesterol. HDL has anti-inflammatory properties, and the use of Apo A-I mimetic peptides is associated with renal function improvement in animal models of sepsis. However, it is not known whether decreased HDL level results in impaired renal function in human sepsis. We investigated whether low levels of HDL conferred an increased risk of sepsis-associated acute kidney injury (AKI) or long-term decreased estimated glomerular filtration rate (eGFR) after sepsis...
