Eileen Ciccia, Prasad Devarajan
The incidence of pediatric acute kidney injury (AKI) is increasing globally, as are the associated morbidities and mortality. A recent standardization of the definition of AKI has allowed for a more accurate assessment of the epidemiology of pediatric AKI. Recent advances in leveraging electronic medical health record systems have allowed for real-time risk stratification and prevention of pediatric AKI in the hospital setting. Newly developed and validated clinical scores have improved our ability to predict AKI and provide a rational context for biomarker utilization in hospitalized children...

Approximately 30% of all cancer patients treated with cisplatin, a widely used, broad-spectrum chemotherapeutic agent, experience acute kidney injury (AKI). Almost all patients receiving cisplatin have magnesium (Mg) losses, which are proposed to aggravate AKI. Currently, there are no methods to successfully treat or prevent cisplatin-AKI. While Mg supplementation has been shown to reduce AKI in experimental models and several small clinical trials, the effects of Mg status on tumor outcomes in immunocompetent tumor-bearing mice and humans have not been investigated...

PURPOSE: Hypoxia plays a significant role in the pathogenesis of acute kidney injury (AKI). Autophagy protects from AKI. Amino acid deprivation induces autophagy. The effect of L-tryptophan depletion on survival and autophagy in cultures of renal proximal tubular epithelial cells (RPTECs) under hypoxia was evaluated. METHODS: RPTECs were preconditioned in a medium containing or not tryptophan, following culture under hypoxia and treatment with or without the autophagy inhibitor chloroquine...

Activation of Src kinase has been implicated in the pathogenesis of acute brain, liver, and lung injury. However, the role of Src in acute kidney injury (AKI) remains unestablished. To address this, we evaluated the effects of Src inhibition on renal dysfunction and pathological changes in a murine model of AKI induced by ischemia/reperfusion (I/R). I/R injury to the kidney resulted in increased Src phosphorylation at tyrosine 416 (activation). Administration of PP1, a highly selective Src inhibitor, blocked Src phosphorylation, improved renal function and ameliorated renal pathological damage...

Nephrotoxicity is one of major side effects of cisplatin in chemotherapy. Therefore, there is an urgent medical need to develop drugs that may protect kidney from toxicity. In previous study, we found that it showed the protective effects of formononetin against apoptosis by upregulating Nrf2. In this study, we investigated the renoprotective effect of formononetin against cisplatin-induced AKI and tried to elucidate the possible mechanisms. The amelioration of renal function, histopathological changes, and apoptosis in tubular cells was observed after formononetin treatment...

BACKGROUND: Kisspeptin-10 (KP-10), a potent vasoconstrictor and inhibitor of angiogenesis, and its receptor, GPR54, have currently received much attention in relation to pre-eclampsia. However, it still remains unknown whether KP-10 could affect atherogenesis. METHODS AND RESULTS: We evaluated the effects of KP-10 on human umbilical vein endothelial cells, human monocyte-derived macrophages, human aortic smooth muscle cells in vitro, and atherosclerotic lesions in apolipoprotein E-deficient (ApoE(-/-)) mice in vivo...

BACKGROUND: Acute kidney injury (AKI) occurs frequently after liver transplantation and is associated with the development of chronic kidney disease and increased mortality. There is a lack of data on renal blood flow (RBF), oxygen consumption, glomerular filtration rate (GFR) and renal oxygenation, i.e. the renal oxygen supply/demand relationship, early after liver transplantation. Increased insight into the renal pathophysiology after liver transplantation is needed to improve the prevention and treatment of postoperative AKI...

Hereditary amyloid polyneuropathy is a type of protein misfolding disease. Transthyretin (TTR) is a homotetrameric serum protein and TTR tetramer dissociation is the limiting step in amyloid fibril formation. Thus, prevention of TTR dissociation is a promising therapeutic approach and some TTR stabilizers have been approved for the treatment of TTR amyloidosis. CSP-1103 (CHF5074) is a non-steroidal anti-inflammatory derivative that lacks cyclooxygenase inhibitory activity. In vitro, CSP-1103 stabilizes the TTR tetramer by binding to the thyroxine (T4) binding site...

BACKGROUND: Most of the risk models for predicting contrast-induced acute kidney injury (CI-AKI) are available for only postcontrast exposure prediction; however, prediction before the procedure is more valuable in practice. This study aimed to develop a risk scoring system based on preprocedural characteristics for early prediction of CI-AKI in patients after coronary angiography or percutaneous coronary intervention (PCI). METHODS: We prospectively recruited 1777 consecutive patients who were randomized in an approximate 3:2 ratio to create a development data set (n = 1076) and a validation data set (n = 701)...

In Wfs1(-/-)A(y)/a islets, in association with endoplasmic reticulum (ER) stress, D-site-binding protein (Dbp) expression decreased and Nuclear Factor IL-3 (Nfil3)/E4 Promoter-binding protein 4 (E4bp4) expression increased, leading to reduced DBP transcriptional activity. Similar alterations were observed with chemically-induced ER stress. Transgenic mice expressing E4BP4 under the control of the mouse insulin I gene promoter (MIP), in which E4BP4 in β-cells is expected to compete with DBP for D-box, displayed remarkable glucose intolerance with severely impaired insulin secretion...

Regardless of whether a randomized trial finds a statistically significant effect for an intervention or not, readers often wonder if the trial was large enough to be conclusive. To answer this question, we can estimate the required sample size for a trial by considering how commonly the outcome occurs, the smallest effect of clinical importance and the acceptable risk of falsely detecting or rejecting that effect. But when is a meta-analysis conclusive? We explain and illustrate the interpretation of Trial Sequential Analysis (TSA), a method increasingly used to answer this question...

BACKGROUND.: Acute kidney injury (AKI) is a frequent complication in patients under mechanical ventilation (MV). We aimed to assess the risk factors for AKI with particular emphasis on those potentially preventable. STUDY DESIGN, SETTING AND PARTICIPANTS.: Retrospective analysis of a large, multinational database of MV patients with >24 hours of MV and normal renal function at admission. AKI was defined according to creatinine-based KDIGO criteria. Risk factors were analyzed according to the time point at which AKI occurred: early (≤48 hours after ICU admission, AKIE) and late (day 3 to day 7 of ICU stay, AKIL)...

Acute kidney injury (AKI) is a common condition in critically ill patients. Multiple studies have identified AKI as a strong independent risk factor for higher morbidity and mortality. AKI is often multifactorial, asymptomatic and difficult to predict. In recent years, the discovery of several AKI biomarkers, including the recent validation and approval of cell cycle arrest biomarkers (NephroCheck, Astute Medical, San Diego, CA, USA), has provided additional tools to detect patients at high risk of AKI and improve their outcomes...
