Renal fibrosis is the central pathogenic process in progression of chronic kidney disease (CKD). Collagen type VI (COL VI) is upregulated in renal fibrosis. Endotrophin is released from COL VI and promotes pleiotropic pro-fibrotic effects. Kidney disease severity varies considerably and accurate information regarding CKD progression may improve clinical decisions. We tested the hypothesis that urinary endotrophin derived during COL VI deposition in fibrotic human kidneys is a marker for progression of CKD in the Renal Impairment in Secondary Care (RIISC) cohort, a prospective observational study of 499 CKD patients...

Chronic kidney disease (CKD) is a prevalent cause of morbidity and mortality worldwide. A hallmark of CKD progression is renal fibrosis characterized by excessive accumulation of extracellular matrix (ECM) proteins. In this study, we aimed to investigate the correlation of the urinary proteome classifier CKD273 and individual urinary peptides with the degree of fibrosis. In total, 42 kidney biopsies and urine samples were examined. The percentage of fibrosis per total tissue area was assessed in Masson trichrome stained kidney tissues...

INTRODUCTION: It may be difficult to differentiate acute kidney injury from chronic kidney disease in patients with no past medical reports of kidney function. This study aimed to investigate the role of serum hyaluronic acid (HA), which is known as a marker of fibrosis, in differential diagnosis of kidney failure. MATERIALS AND METHODS: A total of 90 patients (52 women and 38 mne) admitted to our renal unit with uremia for the first time were included. Serum HA level was measured...

Background/Aims: Patients with chronic kidney disease (CKD) have been found to show markedly increased rates of end-stage renal disease, major adverse cardiovascular and cerebrovascular events (MACCEs), and mortality. Therefore, new biomarkers are required for the early detection of such clinical outcomes in patients with CKD. We aimed to determine whether the level of circulating renalase was associated with CKD progression, MACCEs, and all-cause mortality, using data from a prospective randomized controlled study, Kremezin STudy Against Renal disease progression in Korea (K-STAR; NCT 00860431)...

Extracellular vesicles are cell-derived membrane particles ranging from 30 to 5,000 nm in size, including exosomes, microvesicles, and apoptotic bodies. They are released under physiological conditions, but also upon cellular activation, senescence, and apoptosis. They play an important role in intercellular communication. Their release may also maintain cellular integrity by ridding the cell of damaging substances. This review describes the biogenesis, uptake, and detection of extracellular vesicles in addition to the impact that they have on recipient cells, focusing on mechanisms important in the pathophysiology of kidney diseases, such as thrombosis, angiogenesis, tissue regeneration, immune modulation, and inflammation...

Procalcitonin has emerged as a reliable marker of acute bacterial infection in hospitalized patients and the assay has recently been incorporated into several clinical algorithms to reduce antimicrobial overuse, but its use in patients with end-organ dysfunction is controversial. Areas covered: In this review, the authors examine what is known about procalcitonin testing in patients with organ dysfunction, including those with end-stage renal disease, congestive heart failure, chronic obstructive pulmonary disease, and cirrhosis, and explore how the assay is now being used in the management of non-infectious diseases...

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...

Background: In type 2 diabetes mellitus (T2DM) patients, chronic kidney disease (CKD) progression may occur without detectable changes in urinary albumin excretion (UAE) rate. A new urinary peptide classifier (CKD273) has exhibited greater ability to detect CKD progression, however, its cost-effectiveness remains unknown. This study evaluated the cost-effectiveness of screening for CKD progression with the CKD273 classifier, as compared to UAE, in diabetic patients. Methods: A decision-analytic Markov model was developed to estimate costs and health outcomes [including overall survival and quality-adjusted life years (QALYs)] from a health system perspective for adopting a new annual screening strategy based on the CKD273 classifier as compared to annual UAE-based screening in a hypothetical cohort of T2DM patients...

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...

 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...

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...

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...

PURPOSE OF REVIEW: Drug-induced kidney injury (DIKI) is an important and potentially modifiable cause of acute kidney injury (AKI). The reliance on traditional markers of kidney injury to diagnose DIKI impedes early detection. Biomarkers of DIKI that facilitate early diagnosis and the identification of high-risk patients are essential to ameliorate the clinical burden of this complication. RECENT FINDINGS: Recent progress in this area supports the potential utility of several biomarkers for the diagnosis of DIKI, for the prediction of outcomes and also for monitoring responses to potential nephrotoxic or beneficial therapies...

Fibroblast Growth Factor (FGF)-23 increase is considered one of the earliest biochemical abnormalities in chronic kidney disease-mineral bone disorder (CKD-MBD). Furthermore, accumulating data have provided evidence of a link between increased FGF-23 levels and cardiovascular morbidity and mortality in CKD patients as well as in several other populations including cardiology patients and general population. The cellular and molecular mechanisms underlying the deleterious effect of FGF-23 on the cardiovascular system are not yet completely defined and are the focus of intense research...

Background: Chronic kidney disease (CKD) in childhood is poorly explained by routine markers (e.g. urea and creatinine) and is better depicted in adults by other uraemic toxins. This study describes concentrations of representative uraemic toxins in non-dialysis CKD versus healthy children. Methods: In 50 healthy children and 57 children with CKD Stages 1-5 [median estimated glomerular filtration rate 48 (25th-75th percentile 24-71) mL/min/1.73 m 2 ; none on dialysis], serum concentrations of small solutes [symmetric and asymmetric dimethyl-arginine (SDMA and ADMA, respectively)], middle molecules [β2-microglobuline (β2M), complement factor D (CfD)] and protein-bound solutes [ p -cresylglucuronide (pCG), hippuric acid (HA), indole-acetic acid (IAA), indoxyl sulphate (IxS), p -cresyl sulphate (pCS) and 3-carboxy-4-methyl-5-propyl-furanpropionic acid (CMPF)] were measured...

Background: The diagnosis of glomerular diseases is based on the evaluation of histological lesions in renal tissue by means of light and electronic microscopy, and immunofluorescence technique. Frozen and archival formalin-fixed paraffin-embedded kidney biopsies represent a stored resource for high-throughput technologies. Transcriptomics makes it possible to study the whole gene-expression profile of cells and tissues in a specific period and/or condition. The results, whether considered alone or integrated with other omics data, could help to improve existing knowledge about the pathogenetic mechanisms of glomerulopathies...

Diabetic nephropathy (DN), also named diabetic kidney disease (DKD), is a devastating complication in patients with both type 1 and 2 diabetes mellitus (T1D and T2D) and its diagnosis has been traditionally based on the presence of micro-albuminuria (MA). The aim of this article is to update, through review of the relevant medical literature, the most promising biomarkers for early DKD detection. MA has historically been employed as an early marker of microvascular complications, indicating risk for advanced CKD...
