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...

PURPOSE: Renal injury in term and pre-term neonates may be an antecedent to chronic kidney disease in the child's further life. The aim of the paper was to compile a reference range for selected serum and urinary renal markers in the neonatal period for full-term (FT) and pre-term (PT) newborns. MATERIAL AND METHODS: The prospective study included 23 FT infants (birth weight - BW≥2500g and gestational age - GA≥37Hbd) and 32 PT children (BW<2500g and GA<37Hbd) in good general condition, without acute kidney injury (AKI) or sepsis...

Fibrosis is a common response to injury but can also perpetuate tissue dysfunction. Transient receptor potential C6 (TRPC6) is implicated in cardiac and skin healing via regulation of myofibroblast differentiation. Wu et al. now demonstrate a role for TRPC6 in renal fibrosis, via a mechanism that also relies on TRPC3 and is antagonized by soluble klotho. Modulation of TRPC3/6 activity may provide a means of dampening the fibrotic response involved in chronic kidney disease progression.

BACKGROUND: Information on the epidemiology of Acute Kidney Injury (AKI) in children is scarce. We performed a single center retrospective cohort study to analyze the incidence of AKI, the male/female ratio, the underlying etiology, and age at presentation. We also aimed to assess outcome measured by mortality, duration of PICU stay, and development of Chronic Kidney Disease (CKD). METHODS: Records were searched for children presenting with or developing AKI between 1st January 2008 and 1st January 2015...

Iron is an essential element for all living organisms, but produces toxic oxidants. Thus, iron homeostasis is tightly regulated in mammals. Hepcidin-25 (hepcidin) has emerged as a molecule that regulates iron metabolism. Binding of hepcidin to its receptor, ferroportin, inhibits intestinal iron absorption and iron efflux from hepatocytes and macrophages. Decreased hepcidin enhances iron absorption and efflux. Hepcidin could be predictive of iron status and the response to iron supplementation or erythropoietin-stimulating agents...

BACKGROUND: Ischemic injury during organ transplantation increases the risk of acute and chronic rejections by promoting alloimmune responses. Measurement of neutrophil gelatinase-associated lipocalin (NGAL) immediately after kidney transplantation may be promising for early detection of ischemic injuries to allograft. OBJECTIVE: This study assessed possible predictive values of plasma NGAL levels during first hours after kidney transplantation for graft loss within the first 3 months after transplantation...

Chronic kidney disease (CKD) and macular degeneration (MD) are 2 grave diseases leading to significant disability secondary to renal failure and blindness. The 2 diseases share not only common risk factors but also similar pathogenic mechanisms to renal and retinal injuries. Previous epidemiological studies indicated association between these 2 diseases. However, this concept is challenged by recent investigations. Patients with mild to moderate CKD (n = 30,696) between January 1, 1995 and December 31, 2005 were selected from the Taiwan National Health Insurance Database...

Both cardiac and kidney diseases are extremely common in the population and are intimately interconnected. First, both conditions share several etiological factors (e.g., hypertension, diabetes mellitus). Second, a steady stream of studies has highlighted the negative heart-kidney interaction in such a way that any acute or chronic dysfunction of the former may affect the latter, and reciprocally, as part of the cardiorenal syndromes [1].

In recent years, among patients treated with anticancer chemotherapy, the rate of chronic kidney disease has been increasing. Nephropathy is a major potential adverse event in cancer drug therapy. Anticancer chemotherapy, particularly in patients with comorbid chronic kidney disease, requires sufficient examination of the balance between the potential therapeutic benefit and the risk of decreased renal function. The overwhelming diversity of drugs used to treat cancer involves equally diverse nephropathy pathologies and dose adjustments...

Lung ischemia reperfusion injury (LIRI) is one of important complications following lung transplant and cardiopulmonary bypass. Although patients on hemodialysis are still excluded as lung transplant donors because of the possible effects of renal failure on the lungs, increased organ demand has led us to evaluate the influence of chronic kidney disease (CKD) on LIRI. A CKD model was induced by feeding Sprague-Dawley rats an adenine-rich (0.75%) diet for 2, 4 and 6 weeks, and an isolated rat lung in situ model was used to evaluate ischemia reperfusion (IR)-induced acute lung injury...

Being a member of the IL-17 family, comprising six structurally related ligands, IL-17A is a cytokine, produced by multiple cell types, such as CD4(+)αβ T cells, γδ T cells, natural killer cells, neutrophils, macrophages, dendritic cells, lymphoid tissue inducer cells, mast cells and plasma cells. IL-17A participates in tissue inflammation by inducing the expression of chemokines, proinflammatory cytokines and matrix metalloproteases. Besides its role in host defence against infectious diseases, IL-17A is involved in different autoimmune and inflammatory diseases...

OBJECTIVES: Pneumonia is a common cause of hospitalization and can be complicated by the development of acute kidney injury. Acute kidney injury is associated with major adverse kidney events (death, dialysis, and durable loss of renal function [chronic kidney disease]). Because pneumonia and acute kidney injury are in part mediated by inflammation, we hypothesized that when acute kidney injury complicates pneumonia, major adverse kidney events outcomes would be exacerbated. We sought to assess the frequency of major adverse kidney events after a hospitalization for either pneumonia, acute kidney injury, or the combination of both...

Acute kidney injury (AKI) is associated with incremental risk for death and chronic kidney disease and represents a mounting clinical challenge for healthcare professionals. Renal replacement therapy (RRT) use in ICU settings is rising, likely in response to similar trends in AKI, taken together with an ageing population burdened by high prevalence of multi-morbidity and high illness acuity. Numerous features of RRT prescription and delivery are not standardized, nor are they supported from high-quality evidence derived from randomized trials...
