BACKGROUND: Hepcidin is the main regulator of hepcidin-ferroportin axis and is elevated in children with chronic kidney disease (CKD). Anemia of CKD and its relation to hepcidin, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and high-sensitivity C-reactive protein (hs-CRP) in iron- and erythropoietin (EPO)-naïve, non-dialyzed children with CKD is under-studied. MATERIALS AND METHODS: This case-control study aimed to study the levels of hepcidin and other proinflammatory markers (IL-6, TNF-α, hs-CRP) and their relation with anemia in iron- and erythropoietin-naïve, non-dialysis CKD (stage 3 - 5) patients...

Objectives The aim of this study was to describe the variability in renal function markers in non-azotaemic and azotaemic cats, and also the rate of change in the markers. Methods Plasma creatinine concentration and its reciprocal, glomerular filtration rate (GFR) and urine specific gravity (USG) were studied as markers of renal function in client-owned cats. GFR was determined using a corrected slope-intercept iohexol clearance method. Renal function testing was performed at baseline and a second time point...

Reliable markers for the rapid discrimination of severe renal damage remain a vital concern for lupus nephritis (LN). To determine a better tool for kidney damage detection, the present study compared the evaluation ability of novel urinary cytokines and chemokines (namely urinary monocyte chemoattractant protein 1 (uMCP-1), tumor necrosis factor-like weak inducer of apoptosis (uTWEAK)) with traditional serum or urinary markers (namely urinary alpha 1-microgrobulin (uα1-MG), beta 2-microglobulin (uβ2-MG) and serum complement C3 (C3), complement C4 (C4), creatinine (Cr), blood urea nitrogen (BUN) and cystatin C (Cys C)) in discriminating LN renal damage...

BACKGROUND: Chitinase-3-like 1 (CHI3L1) is a glycoprotein elevated in paediatric severe malaria, and an emerging urinary biomarker of acute kidney injury (AKI). Based on the hypothesis that elevated CHI3L1 levels in malaria are associated with disease severity, the relationship between plasma CHI3L1 levels, AKI and mortality was investigated in Ugandan children enrolled in a clinical trial evaluating inhaled nitric oxide (iNO) as an adjunctive therapy for severe malaria. METHODS: Plasma CHI3L1 levels were measured daily for 4 days in children admitted to hospital with severe malaria and at day 14 follow up...

Chronic kidney disease-mineral and bone disorder (CKD-MBD) is a complex disease which is associated with alterations of bone and mineral metabolism. miR-223 is implicated in both vascular calcification and osteoporosis. In the present study, we investigated the influence of Stab1 gene on miRNA-223 expression in osteoclastogenesis. Differentiation of monocyte/macrophage precursors was assessed by using RAW264.7 cells and peripheral blood mononuclear cells (PBMC). TRAP activity and bone resorption were used to measure osteoclast activity...

Epithelial-mesenchymal transition (EMT) is a critical step and key factor during renal fibrosis. Preventing renal tubular EMT is important for delaying the progression of chronic kidney disease (CKD). P311, a highly conserved 8-kDa intracellular protein, has been indicated as an important factor in myofibroblast transformation and in the progression of fibrosis. However, the related studies on P311 on renal fibrosis are limited and the mechanisms of P311 in the progression of renal tubulointerstitial fibrosis remain largely unknown...

Vascular calcification (VC) occurs in patients with chronic kidney disease (CKD) and contributes to cardiovascular dysfunction and mortality. Parathyroid hormone (PTH) is a crucial regulator of VC. High PTH serum levels constitute as a major risk factor for patients with CKD. However, the effect and mechanism of PTH on osteoblastic differentiation in endothelial cells have not been fully elucidated. In the present study, the role of PTH in VC was investigated using an in vitro calcification model. Endothelial cells were stimulated with PTH in the femto- to picomolar range...

Children are at increased risk of developing metabolic syndrome (MS) after kidney transplantation, which contributes to long-term cardiovascular (CV) morbidities and decline in allograft function. While MS in the general population occurs due to excess caloric intake and physical inactivity, additional chronic kidney disease and transplant-related factors contribute to the development of MS in transplant recipients. Despite its significant health consequences, the interplay of the individual components in CV morbidity in pediatric transplant recipients is not well understood...

Oxidative stress plays a key role in the pathophysiological process of uremia and its complications, particularly in cardiovascular disease. The level of oxidative stress markers is known to increase as chronic kidney disease progresses and correlates significantly with the level of renal function. Hemodialysis and peritoneal dialysis are major modes of renal replacement therapy for end-stage renal disease patients, but unfortunately they are also accompanied by increased oxidative stress. Successful kidney transplantation, however, results in near normalization of the antioxidant status and lipid metabolism by eliminating free radicals despite the surge of oxidative stress caused by the surgical procedure and ischemic injury to the organ during the operation...

OBJECTIVES: Vitamin D-binding protein (VDBP), retinol-binding protein (RBP)4, and heat shock proteins (hsp) are markers of tubular function and apoptosis, accompanying chronic kidney disease (CKD) from its earliest stages. Fractional excretion of proteins with urine is a marker of tubular damage. The aim of study was to assess the usefulness of fractional excretion (FE) of VDBP, RBP4, HSF1 and Hsp27 as markers of tubular damage in the course of CKD. METHODS: The study group consisted of 70 children with CKD stages 1-5, treated conservatively, and 12 age-matched controls with normal kidney function...

Background: Viral infections can trigger chronic kidney disease (CKD) and the urine virome may inform risk. The Natural History of APOL1-Associated Nephropathy Study (NHAANS) reported that urine JC polyomavirus (JCPyV) associated with a lower risk of APOL1-associated nephropathy in African Americans. Herein, association was assessed between urine JCPyV with CKD in African Americans independent from the APOL1 genotype. Methods: Quantitative polymerase chain reaction was performed for urinary detection of JCPyV and BK polyoma virus (BKPyV) in 200 newly recruited nondiabetic African Americans...

A facile label free, ultrasensitive platform for a rapid detection of chronic kidney disease has been fabricated. Early intervention in patients with chronic kidney disease has the potential to delay, or even prevent, the development of end stage renal disease and complications, leading to a marked impact on life expectancy and quality of life. Thus, a potable electrochemical diagnostic biosensor has become an attractive option as electrochemical analysis is feasible to use for on-site detection of samples...

BACKGROUND AND AIMS: The components of the renin-angiotensin system in leukocytes is involved in the pathophysiology of non-communicable diseases (NCDs), including hypertension, atherosclerosis and chronic kidney disease. Angiotensin II type 1 receptor (AT1R)-associated protein (ATRAP) is an AT1R-specific binding protein, and is able to inhibit the pathological activation of AT1R signaling in certain animal models of NCDs. The aim of the present study was to investigate the expression and regulation of ATRAP in leukocytes...

BACKGROUND: Hyponatremia is a common electrolyte disorder and a prognostic marker for mortality. We hypothesize that in advanced chronic or acute kidney disease, hyponatremia is not independently associated with mortality because of the contribution of kidney failure to its pathophysiology. METHODS: Clinical Looking Glass, Montefiore's clinical database, was used to build a cohort of all patients hospitalized between January of 2009 and December of 2011. A chronic kidney disease (CKD) group and an acute kidney injury (AKI) group were defined based on GFR measurements during and before index hospitalization...

BACKGROUND: Untreated severe obesity of adolescents is associated with abnormal kidney function and development of chronic kidney disease. Lipotoxicity due to lipid accumulation in glomeruli might be an important mechanism in the progression of kidney disease in obesity. OBJECTIVE: To assess subclinical glomerular injury by measuring urinary sphingolipids in adolescents with severe obesity before and after weight loss surgery. We hypothesized that the levels of urinary sphingolipids would be elevated at baseline and improve after weight reduction...

BACKGROUND: Acute kidney injury (AKI) is associated with both short- and long-term clinical consequences including progression to chronic kidney disease. Recovery of renal function has gained importance, as interventions to prevent or treat AKI are limited. Basing recovery on a return of serum creatinine values excludes mounting evidence that AKI, even when reversible, is a very serious clinical event that will result in a significant number of both renal and extra-renal complications such as late stage kidney disease, major cardiovascular events, and death...
