Soluble urokinase plasminogen activator receptor (suPAR) independently predicts chronic kidney disease (CKD) incidence and progression. Apolipoprotein L1 (APOL1) gene variants G1 and G2, but not the reference allele (G0), are associated with an increased risk of CKD in individuals of recent African ancestry. Here we show in two large, unrelated cohorts that decline in kidney function associated with APOL1 risk variants was dependent on plasma suPAR levels: APOL1-related risk was attenuated in patients with lower suPAR, and strengthened in those with higher suPAR levels...

In clinical setting, congestive heart failure (CHF) and chronic kidney disease (CKD) often co-exist in patients due to common underlying predisposing factors. An intricate equilibrium between the cardiovascular and renal system is maintained through rennin angiotensin-aldosterone axis and autonomic nervous system. Consequent to favorable hemodynamic modification, angiotensin converting enzyme inhibitors (ACEI) and angiotensin receptor blocking (ARB) therapy have proven to be an indispensable aspect of heart failure management with morbidity and mortality benefit...

BACKGROUND: Using change in estimated glomerular filtration rate (eGFR) based on creatinine concentration as a surrogate outcome in clinical trials of chronic kidney disease has been proposed. Risk for end-stage renal disease (ESRD) and all-cause mortality associated with change in concentrations of other filtration markers has not been studied in chronic kidney disease populations. STUDY DESIGN: Observational analysis of 2 clinical trials. SETTING & PARTICIPANTS: Participants in the MDRD (Modification of Diet in Renal Disease; n=317) Study and AASK (African American Study of Kidney Disease and Hypertension; n=373)...

Immune cells infiltrating the tubulointerstitium critically contribute to the progression of chronic kidney disease. In this issue of Kidney international, Law et al. provide first evidence for a role of natural killer cells in the perpetuation of tubulointerstitial fibrosis in human renal disease. By detailed flow cytometric characterization of leukocytes isolated from kidney biopsies of chronic kidney disease patients, they define accumulation of natural killer cells as a feature of fibrotic kidney tissue and provide insight into potential mechanisms of how these cells might promote chronic kidney inflammation...

In this issue, Ferguson and colleagues demonstrate that chronic kidney disease (CKD) screening in populations burdened with CKD may be cost effective. Whether we should screen for CKD, however, continues to be debated despite the availability of effective clinical strategies that mitigate the risks of CKD progression. This study highlights the need for pragmatic trials to test the effectiveness of early CKD detection combined with optimization of clinical management and calls for innovation to tackle CKD.

AIMS/INTRODUCTION: Diabetic nephropathy is one of the leading causes of end-stage renal disease. Unfortunately, reliable surrogate markers for predicting the prognostic outcome of diabetic nephropathy were as yet absent. In order to find new markers in predicting the progression of diabetic nephropathy, we conducted a prospective study by investigating the correlation between serum metabolites and the annual change of estimated glomerular filtration rate (eGFR). MATERIALS AND METHODS: From September 2013 to September 2015, 52 diabetic patients at various stages of chronic kidney disease (CKD) were enrolled...

Renal fibrosis is a common pathological pathway of various chronic kidney diseases progressing to end-stage renal disease and is characterized by tubular atrophy, fibroblast/myofibroblast activation and excessive deposition of extracellular matrix (ECM). N-Myc downstream-regulated gene-2 (NDRG2) is reported to be associated with liver fibrosis in rats. However, the biological function of NDRG2 in renal fibrosis remains unclear. Therefore, we investigate the effect of NDRG2 on renal fibrosis and the underlying mechanism of NDRG2 in TGF-β1-induced renal tubular epithelial cells (HK-2)...

INTRODUCTION: Chronic kidney disease (CKD) is associated with an increased risk of cardiovascular disease and mortality, which is thought to be caused by increased propensity towards vascular calcification (VC). Magnesium (Mg) inhibits phosphate-induced VC in vitro and in animal models and serum Mg is inversely associated with cardiovascular mortality in predialysis CKD and in end-stage renal disease. This paper will describe the design and rationale of a randomised double-blinded placebo-controlled multicentre clinical trial, which will investigate whether oral Mg supplementation can prevent the progression of coronary artery calcification (CAC) in subjects with predialysis CKD...

Chronic kidney disease (CKD) is a worldwide public health problem that is growing in prevalence and is associated with severe complications. During the progression of the disease, a majority of CKD patients suffer oral complications. Dental implants are currently the most reliable and successful treatment for missing teeth. However, due to complications of CKD such as infections, bone lesions, bleeding risks, and altered drug metabolism, dental implant treatment for renal failure patients on dialysis is more challenging...

COMMENT
Maria D Sanchez-Niño, Alberto Ortiz
In this issue of CKJ, McQuarrie et al. have explored the relationship between socioeconomic status and outcomes among Scottish patients with a renal biopsy diagnosis of primary glomerulonephritis. Patients in the lower socioeconomic category had a twofold higher risk of death. No significant differences were observed on progression to end-stage renal disease (ESRD) requiring renal replacement therapy (RRT), suggesting that overall medical management was appropriate for all socioeconomic categories. The findings are significant since they come from an ethnically homogeneous population with free access to healthcare; they also relate to a specific aetiology of chronic kidney disease (CKD) expected to be less dependent on unhealthy lifestyles than other more frequent aetiologies that dominate studies of CKD in general, such as diabetic or hypertensive nephropathy...

Epithelial-mesenchymal transition (EMT) refers to the transition of epithelial cells into mesenchymal cells. Emerging evidence suggests that EMT is a key point in renal interstitial fibrosis (RIF). Traditional Chinese Medicine Shenqiwan (SQW) is widely used in clinical treatment of chronic kidney disease, but the underlying mechanism remains unclear. The purpose of this study is to investigate the effect of SQW on renal fibrosis and its association with TGF-β1/Smads signaling pathway. A rat model of adenine (150 mg/kg) was established and intragastrically treated with various concentrations of SQW at dose of 1...

IgA nephropathy (IgAN), a frequent cause of chronic kidney disease worldwide, is characterized by mesangial deposition of galactose-deficient IgA1-containing immune complexes. Complement involvement in IgAN pathogenesis is suggested by the glomerular deposition of complement components and the strong protection from IgAN development conferred by the deletion of the CFHR3 and CFHR1 genes (ΔCFHR3-CFHR1). Here we searched for correlations between clinical progression and levels of factor H (FH) and FH-related protein 1 (FHR-1) using well-characterized patient cohorts consisting of 112 patients with IgAN, 46 with non-complement-related autosomal dominant polycystic kidney disease (ADPKD), and 76 control individuals...

Chronic kidney disease (CKD) has a prevalence of approximately 13% and is most frequently caused by diabetes and hypertension. In population studies, CKD etiology is often uncertain. Some experimental and observational human studies have suggested that high-protein intake may increase CKD progression and even cause CKD in healthy people. The protein source may be important. Daily red meat consumption over years may increase CKD risk, whereas white meat and dairy proteins appear to have no such effect, and fruit and vegetable proteins may be renal protective...

BACKGROUND: Secondary Hyperparathyroidism (SHPT) requiring parathyroidectomy (PTX) occurs more commonly in patients with progressive chronic kidney disease and in those on long-term lithium therapy. Successful PTX often results in a dramatic drop of parathyroid hormone level, relieves the patient from clinical symptoms, and reduces mortality. However, there is an ongoing debate on the optimal surgical treatment of SHPT. Currently, no clinical guidelines or trials have definitely answered the question of whether Total Parathyroidectomy (TPTX) is superior or equal to Total Parathyroidectomy with Autotransplantation (TPTX + AT)...

BACKGROUND: We aimed to evaluate the potential benefits of N-acetylcysteine (NAC) on the risk of chronic kidney disease (CKD) progression to dialysis-requiring end-stage renal disease (ESRDd). METHODS: In a population-based cohort study of 145,062 individuals, 123,608 CKD patients who were followed up for 10years were included, and CKD patients treated with NAC (ICD-9-CM) were compared with those who were not treated. Using propensity score matching, we analyzed the predictors of CKD progression to ESRDd by Cox proportional hazards regression with adjustments for sex, age, and comorbidities, and evaluated the effect of NAC using cumulative defined daily dose (cDDD)...

Chronic kidney disease (CKD) patients have a high burden of cardiovascular disease. In the general population, lipid metabolism disorders, which cause the initiation and progression of atherosclerotic vascular changes, are major targets for preventive and therapeutic strategies in cardiovascular medicine. However, data from large cohort studies and from clinical trials suggest that the treatment guidelines on cardiovascular disease prevention and therapy cannot uncritically be transferred from individuals with intact renal function to CKD patients...

Obesity is associated with an increased risk of chronic kidney diseases and the conventional treatment with renin-angiotensin-aldosterone system (RAAS) inhibitors is not enough to prevent renal injury and prolong the progression of disease. Recently, silymarin has shown protective effects on renal tissue injury, but the underlying mechanisms remain elusive. The goal of this study was to investigate the potential capacity of silymarin to prevent renal injury during obesity induced by high fat diet (HFD) in mice...

Type 2 diabetes mellitus (T2DM) is one of the most common causes of chronic kidney disease and kidney failure. It has been estimated that the annual decline of estimated glomerular filtration rate (eGFR) among patients with T2DM is approximately 2.0-2.5mL min(-1) y(-1). Cyclooxygenase-dependent eicosanoids, such as 11-dehydro-thromboxane (Tx)B2, are increased in T2DM patients and are potentially involved in the regulation of renal blood flow. Animal models showed that cyclooxygenase inhibitors, such as aspirin, are associated with improvements in renal plasma flow and eGFR values...
