The Lidanpaidu Prescription (LDP), a hospital preparation, composed of Chinese classical preparations, has been reported to have antiendotoxin, anticoagulant and other effects. However, its therapeutic effect on lipopolysaccharide (LPS)-induced acute kidney injury (AKI) and the mechanisms remain unclear. Therefore, we administered LPD pretreatment at different doses to examine the protective effects and mechanisms in LPS-induced AKI in mice. The kidney injury induced by LPS was assessed by histological examination...

BACKGROUND Acute kidney injury (AKI) secondary to sepsis is a major cause of morbidity and mortality in the human intensive care unit (ICU). Kidney function and the histological findings of AKI were investigated in an experimental rat model with sepsis induced by cecal ligation and puncture (CLP) and compared with and without treatment with carnosine (beta-alanyl-L-histidine). MATERIAL AND METHODS Twenty-four Sprague-Dawley rats were randomly divided into three groups consisting eight rats in each: Group 1 - control; Group 2 - septic shock; and Group 3 - septic shock treated with carnosine...

CONTEXT: Acute kidney injury (AKI) can occur after carbon monoxide (CO) intoxication; however, limited data are available. This study aimed to evaluate the prognostic value of the development and progression of AKI in patients with acute CO poisoning. MATERIALS AND METHODS: We conducted a retrospective cohort study using a prospective registry of CO poisoning between January 2010 and December 2015. AKI was defined and classified according to the Kidney Disease Improving Global Outcomes (KDIGO) criteria...

The cause of acute kidney injury during pregnancy and in the postpartum period can be particularly challenging to diagnose, especially when it is necessary to differentiate among preeclampsia; eclampsia; hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome; and thrombotic microangiopathies (TMAs). All these disease entities can present with kidney failure, microangiopathic hemolytic anemia, and thrombocytopenia. We present a teaching case of atypical hemolytic uremic syndrome in the postpartum period in a young woman who was found to have mutations of uncertain clinical significance in the complement cascade, including in C3, CFH, and CFI...

BACKGROUND: It is unclear whether pathologic findings on preoperative urinalysis are associated with the risk of postoperative acute kidney injury (AKI). Therefore, we performed a retrospective review to investigate this association. METHODS: We assessed the clinical significance of preoperative dipstick urinalysis in a 10-year surgery cohort from a tertiary hospital in Korea. Patients without available information on perioperative serum creatinine levels or kidney injury prior to surgery were excluded...

Acute kidney injury (AKI) after transcatheter aortic valve implantation (TAVI) is associated with increased mortality. As significant hemodynamic improvement may occur with relief of aortic stenosis, we hypothesized that TAVI patients may demonstrate the opposite phenomena: acute kidney recovery (AKR). We studied the incidence and predictors of AKR in post-TAVI patients. A total of 366 consecutive patients underwent TAVI (January 2012 to January 2017) at a single center. We defined AKR as a 25% improvement in glomerular filtration rate (GFR) at 48 hours after TAVI...

AIM: To evaluate the incidence, risk factors, and prognostic implications of contrast medium-induced acute kidney injury (CI-AKI) in patients undergoing transcatheter aortic valve implantation (TAVI) evaluation. MATERIALS AND METHODS: Datasets from 98 out of 207 consecutive patients referred for multidetector computed tomography (MDCT) for TAVI evaluation were eligible for evaluation and were analysed retrospectively. The incidence of CI-AKI was correlated to outcome and to potential risk factors: kidney function (estimated glomerular filtration rate [eGFR]), heart failure, diabetes, amount of contrast medium, and duration of examination period...

Background: Colistin (polymyxin E) is an important constituent of the polymyxin class of cationic polypeptide antibiotics. Intrarenal oxidative stress can contribute to colistin-induced nephrotoxicity. Nicotinamide adenine dinucleotide 3-phosphate oxidases (Noxs) are important sources of reactive oxygen species. Among the various types of Noxs, Nox4 is predominantly expressed in the kidney. Objectives: We investigated the role of Nox4 and benefit of Nox4 inhibition in colistin-induced acute kidney injury using in vivo and in vitro models...

Contrast-induced acute kidney injury (CIAKI) is a leading cause of acute kidney injury following radiographic procedures. Intrarenal oxidative stress plays a critical role in CIAKI. Nicotinamide adenine dinucleotide 3-phosphate (NADPH) oxidases (Noxs) are important sources of reactive oxygen species (ROS). Among the various types of Noxs, Nox4 is expressed predominantly in the kidney in rodents. Here, we evaluated the role of Nox4 and benefit of Nox4 inhibition on CIAKI using in vivo and in vitro models. HK-2 cells were treated with iohexol, with or without Nox4 knockdown, or the most specific Nox1/4 inhibitor (GKT137831)...

BACKGROUND: Acute kidney injury (AKI) is a common complication after liver transplantation and more frequently observed when high-risk grafts, such as DCD grafts are used. Our aim was to investigate the impact of the ischemia periods on development of AKI in DCD liver transplantation. METHODS: We performed a 2-center retrospective study with 368 DCD graft-recipients. Donor warm ischemia time (DWIT) was divided into agonal phase (withdrawal of life-support - cardiac arrest) and asystolic phase (cardiac arrest - start cold perfusion)...

REVIEW
D Kindgen-Milles, T Slowinski, T Dimski
Acute kidney injury (AKI) occurs in 30-50% of all intensive care patients. Renal replacement therapy (RRT) has to be initiated in 10-15%. The early in-hospital mortality is about 50%. Up to 20% of all survivors develop chronic kidney disease after intensive care discharge and progress to end-stage kidney disease within the next 10 years. For timely initiation of prophylactic or therapeutic interventions, it is crucial to exactly determine the actual kidney function, i. e., glomerular filtration rate (GFR), and to gain insight into the further development of kidney function...

BACKGROUND: Current guidelines recommend that rapid systolic blood pressure (SBP) lowering to 140 mmHg may be considered in intracerebral hemorrhage (ICH) patients regardless of initial SBP. However, limited safety data exist in patients presenting with varying degrees of severe hypertension. The purpose of this study was to determine whether there was an increased risk of acute kidney injury (AKI) based upon degree of presentation hypertension in ICH patients whose blood pressure was reduced intensively...

Background: When safe to do so, avoiding blood transfusions in cardiac surgery can avoid the risk of transfusion-related infections and other complications while protecting a scarce resource and reducing costs. This protocol describes a kidney substudy of the Transfusion Requirements in Cardiac Surgery III (TRICS-III) trial, a multinational noninferiority randomized controlled trial to determine whether the risk of major clinical outcomes in patients undergoing planned cardiac surgery with cardiopulmonary bypass is no greater with a restrictive versus liberal approach to red blood cell transfusion...

Renal ischemia-reperfusion injury (IRI) induces local inflammation leading to kidney damage. Since pentoxifylline (PTX) and steroids have distinct immunomodulatory properties, we aimed to evaluate for the first time their combined use in IRI-induced acute kidney injury (AKI) and chronic kidney disease (CKD) in rats. In two experiments, PTX (100 mg/kg body weight subcutaneously) was administered 90 min prior to renal IRI or/and methylprednisolone (MP; 100 mg/kg body weight intramuscularly) was infused 60 min after reperfusion of a solitary kidney (AKI model: 45 min ischemia, 48 male Sprague-Dawley rats) or one kidney with excision of contralateral kidney 2 weeks later (CKD model: 90 min ischemia, 38 rats)...

PURPOSE OF REVIEW: Quality measure assessment and reporting is evolving in end-stage renal disease care and is inchoate in ambulatory nephrology clinic care. Acute kidney injury (AKI) quality measures have not received sufficient attention, yet deserve consideration in view of the substantial proportion of effort nephrology providers devote to AKI care. RECENT FINDINGS: Accumulating literature permits consideration of timing of nephrology consultation, follow-up after AKI hospitalization, early detection, medication dosing, hospital readmissions and length of stay, cost, and mortality as putative AKI quality measures...

PURPOSE OF REVIEW: The increasing incidence of acute kidney injury has the immediate effect of a growing need for renal replacement therapy (RRT). Shedding light on the questions of who, when, why, and how RRT should be performed is difficult to accomplish because of ambiguous study results, poor quality evidence, and low standardization. RECENT FINDINGS: Critically ill patients are exposed to multiple factors known to deteriorate kidney function. Especially severe fluid overload is strongly associated with worse outcome and may be considered as a trigger for initiating RRT...
