BACKGROUND: Impairment in orexigenic/anorexigenic hormone balance may be key in the pathogenesis of protein energy wasting in children with chronic kidney disease (CKD). Measurement of ghrelin and obestatin concentrations in children with CKD would help assess the potential contribution of these hormones to uremic protein energy wasting. METHODS: This was a cross-sectional case-control study. Acylated and unacylated ghrelin and obestatin were measured in 42 children on conservative treatment (CT), 20 children on hemodialysis, 48 pediatric renal transplant (RTx) recipients and 43 controls (CTR) (mean age 11...

MicroRNAs play multiple roles in the regulation of blood pressure (BP). Nevertheless, to date, no study has assessed the association between microRNA plasma expression and BP control in chronic kidney disease (CKD) patients. Given this background, we evaluated the plasma expression of miR-155-5p, a translational inhibitor of angiotensin receptor type I, in CKD patients, to determine the association between miR-155-5p level and BP control. In this single-center cross-sectional study, we analyzed the miR-155-5p concentration by quantitative reverse transcriptase polymerase chain reaction using the U6 snRNA as a reference gene and 24-hour ambulatory blood pressure monitoring in CKD patients (stage ≥2) in relation to a control group of healthy age-matched and gender-matched individuals, with normal BP proven by the ambulatory blood pressure monitoring...

Introduction: Soluble urokinase-type plasminogen activator receptor (suPAR) strongly predicts outcomes and incident chronic kidney disease (CKD) in patients with cardiovascular disease (CVD). Whether the association between suPAR and CKD is a reflection of its overall association with chronic inflammation and poor CVD outcomes is unclear. We examined whether CVD biomarkers, including high-sensitivity C-reactive protein (hs-CRP), fibrin-degradation products (FDPs), heat-shock protein 70 (HSP-70), and high-sensitivity troponin I (hs-TnI) were associated with a decline in kidney function in the Emory Cardiovascular Biobank cohort, in which suPAR levels were shown to be predictive of both incident CKD and CVD outcomes...

The prevalence of chronic kidney disease (CKD) is rising continuously. Cardiovascular disease (CVD) is among the leading causes of death and premature mortality of patients with CKD. It has been suggested that the assessment of CKD-associated CVD risk factors together with conventional risk factors should be performed in order to improve the prediction of coronary heart disease risk. The reduction of these factors seems to be effective in lowering cardiovascular (CV) morbidity and mortality in patients with CKD...

Background: The clinical significance of urinary liver fatty acid-binding protein (u-LFABP) in acute heart failure (AHF) patients remains unclear. Methods and Results: The u-LFABP levels on admission of 293 AHF patients were analyzed. The patients were divided into 2 groups according to the u-LFABP quartiles (Q1, Q2, and Q3 = low u-LFABP [L] group vs. Q4 = high u-LFABP [H] group). We evaluated the diagnostic and prognostic value of u-LFABP and compared the findings between the chronic kidney disease (CKD; n = 165) and non-CKD patients (n = 128)...

Herein, we measure the Ca isotope ratios ((44)Ca/(42)Ca and (43)Ca/(42)Ca) in serum and bone samples collected from rats with chronic kidney disease (CKD) or diabetes mellitus (DM). For the serum samples, the isotope ratios are lower for the CKD (δ(44)Ca/(42)Caserum = 0.16 ± 0.11‰; 2SD, n = 6) and the DM (δ(44)Ca/(42)Caserum = -0.11 ± 0.25‰; 2SD, n = 7) rats than that for the control rats (δ(44)Ca/(42)Caserum = 0.25 ± 0.04‰; 2SD, n = 7). Bone samples from two distinct positions of 20 rats in total, namely, the center and proximal parts of the tibial diaphysis, are subject to Ca isotope analysis...

INTRODUCTION: Quantitative assessment of renal function by measurement of glomerular filtration rate (GFR) is an important part of safety and efficacy evaluation in preclinical drug development. Existing methods are often time consuming, imprecise and associated with animal burden. Here we describe the comparison between GFR determinations with sinistrin (PS-GFR) and fluorescence-labelled sinistrin-application and its transcutaneous detection (TD-GFR) in a large animal model of chronic kidney disease (CKD)...

Chronic kidney disease (CKD) is a progressive pathological condition in which renal function deteriorates in time. The first diagnosis of CKD is often carried out in general care attention by general practitioners by means of serum creatinine (CNN) levels. However, it lacks sensitivity and thus, there is a need for new robust biomarkers to allow the detection of kidney damage particularly in early stages. Multivariate data analysis of plasma concentrations obtained from LC-QTOF targeted metabolomics method may reveal metabolites suspicious of being either up-regulated or down-regulated from urea cycle, arginine methylation and arginine-creatine metabolic pathways in CKD pediatrics and controls...

 In chronic kidney disease (CKD), progressive nephron loss causes tubulointerstitial fibrosis and progressive tubular injury. Recent identification of the major cell populations of myofibroblast precursors in the kidney has enabled us to dissect the fibrogenic process after tubular injury. Kidney pericytes are a possible precursor of myofibroblasts, and may be promising targets for treating fibrogenesis. Our recent studies have shown that pericytes activate Toll-like receptor (TLR) 2/4- and myeloid differentiation primary response 88 (MyD88)-dependent proinflammatory signaling in response to renal tubular injury...

BACKGROUND: Our previous studies indicated that Bmi-1 plays an important role in hypoxia-induced tubular epithelial-mesenchymal transition and the development of kidney fibrosis in cellular and animal models. However, circulating Bmi-1 levels in human chronic kidney disease (CKD) and their relation to progression remains unknown. MATERIALS AND METHODS: We conducted a post-hoc analysis of a prospective cohort study. The blood samples and clinical data of 230 patients with glomerular CKD and 67 healthy adults were prospectively collected between January 2010 and June 2012...

BACKGROUND: Serum biomarkers, such as serum creatinine (SCr) and serum cystatin C (SCysC), have been widely used to evaluate renal function in patients who have chronic kidney disease (CKD). OBJECTIVE: This article aims to assess the value of determining SCr and SCysC levels in patients that have long-term kidney disease. Approaches: MEDLINE, EmBase, the Cochrane Library and other databases were searched using both MeSH terms and text words to collect research that assessed the diagnostic value of using SCr and SCysC to evaluate Glomerular Filtration Rate (GFR) in patients with CKD...

Background: Chronic Kidney Disease (CKD) is a risk factor for contrast induced acute kidney injury (CI-AKI). Contrast angiography in CKD patients is a common procedure. Creatinine is a delayed marker of CI-AKI and delays diagnosis which results in significant morbidity and mortality. Aim: Early diagnosis of CI-AKI requires validated novel biomarkers. Design: A prospective observation study of 301 consecutive CKD patients undergoing coronary angiography was performed...

Acute kidney injury (AKI) occurs in approximately 10% to 15% of hospital-admitted patients and is associated with in-hospital mortality of 50% in patients requiring renal replacement therapy. Recently, multiple observational studies have demonstrated that patients who survive AKI have significant long-term consequences including cardiovascular events, progression to advanced-stage chronic kidney disease (CKD), and mortality. A direct link between AKI and CKD is provided by studies that demonstrate that some patients with normal renal function who develop AKI requiring dialysis never recover...

Background: Sclerostin, a 22-kDa protein secreted by osteocytes, acts as a potent inhibitor of osteoblast activity. In chronic kidney disease (CKD), sclerostin is a putative driver of the bone-vascular axis. However, large discrepancies between sclerostin assays have been described. Methods: We compared four different assays [Biomedica (BM), TecoMedical (TE), R&D (RD) and MesoScaleDiscovery (MSD)] in an analytical study and addressed the question whether bioassay choice affects the correlation between circulating sclerostin and clinical and biochemical determinants...

Dietary sodium intake has been associated with progression to chronic kidney disease (CKD) as well as hypertension. A high-salt intake causes renal damage independent of hypertension. Because traditional renal biomarkers are insensitive, it is difficult to detect renal injury induced by a high-salt intake, especially in normotensive patients. Here, we investigated whether newly developed renal biomarkers could be detected earlier than traditional biomarkers under a high-salt intake, in normotensive rats. Male Wistar Kyoto rats (WKY) received a regular (0...

The development of formulas estimating glomerular filtration rate (eGFR) from serum creatinine and cystatin C and accounting for certain variables affecting the production rate of these biomarkers, including ethnicity, gender and age, has led to the current scheme of diagnosing and staging chronic kidney disease (CKD), which is based on eGFR values and albuminuria. This scheme has been applied extensively in various populations and has led to the current estimates of prevalence of CKD. In addition, this scheme is applied in clinical studies evaluating the risks of CKD and the efficacy of various interventions directed towards improving its course...
