BACKGROUND: Aldose reductase (AR) gene C-106T polymorphism may be associated with diabetic nephropathy (DN) susceptibility, but the results of individual studies remain controversial. OBJECTIVE AND METHODS: To explore the relationship between AR gene C-106T gene polymorphism and DN in the Eastern Asians with type 2 diabetes mellitus (T2DM) population, we conducted a meta-analysis of 2120 participants from 5 studies. Pooled odds ratio (ORs) and the corresponding 95% confidence interval (95% CI) were evaluated by either a fixed or random-effects models...

BACKGROUND: Type 2 diabetes is a major healthcare problem. Glucose-, lipid-, and blood pressure-lowering strategies decrease the risk of micro- and macrovascular complications. However, a substantial residual risk remains. To unravel the etiology of type 2 diabetes and its complications, large-scale, well-phenotyped studies with prospective follow-up are needed. This is the goal of the DiaGene study. In this manuscript, we describe the design and baseline characteristics of the study...

BACKGROUNDS: Kidney hypoxia represents a unifying mechanism in the pathogenesis of diabetic nephropathy. Hypoxia-induced factor (HIF)-1α mediates the metabolic responses of renal hypoxia by modulating the expression of VEGF. In the present study, we investigated the effect of Pueraria tuberosa extract (PTY-2r) on the expression of HIF-1α, VEGF and nephrin in streptozotocin (STZ) induced diabetic nephropathy (DN). METHODS: The model of diabetic nephropathy (DN) was produced by intraperitoneal injection of 55mg/kg of STZ and maintained for 60days...

BACKGROUND: Acute kidney injury (AKI) following primary percutaneous coronary intervention (pPCI) is frequently interpreted as contrast-induced AKI but may result from other insults. We aimed to determine the causal association of contrast material exposure and the incidence of AKI following pPCI using a control group of propensity score-matched patients with ST-segment-elevation myocardial infarction who were not exposed to contrast material. METHODS AND RESULTS: We studied 2025 patients with ST-segment-elevation myocardial infarction who underwent pPCI and 1025 patients receiving fibrinolysis or no reperfusion who were not exposed to contrast material during the first 72 hours of hospital stay (control group)...

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...

REVIEW
Peter Mundel
In this review, I describe a 30-year journey in the quest for precision medicines for patients with kidney diseases. In 1987, when I started my reseach career, most scientists studying glomerular disease biology were focused on mesangial cells. The crucial role of the podocyte in many kidney diseases characterized by proteinuria, including focal segmental glomerulosclerosis (FSGS) and diabetic nephropathy, had not yet been recognized. We were not aware of genetic causes or drivers of kidney diseases nor of molecular markers and cell culture systems for mechanistic studies of podocyte biology...

Hemoglobin glycation index (HGI), calculated as the difference between the observed value of HbA1 and the predicted HbA1c based on plasma glucose concentration, is a measure of the individual tendency toward non-enzymatic hemoglobin glycation which has been found to be positively associated with nephropathy in subjects with diabetes. In this cross-sectional study we aimed to evaluate whether higher HGI levels are associated with impaired kidney function also among nondiabetic individuals.The study group comprised 1505 White nondiabetic individuals stratified in quartiles according to HGI levels...

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...

Podocyte injury and depletion are essential events involved in the pathogenesis of diabetic nephropathy (DN). As a terminally differentiated cell, podocyte is restricted in 'post-mitosis' state and unable to regenerate. Re-entering mitotic phase will cause podocyte disastrous death which is defined as mitotic catastrophe (MC). Murine double minute 2 (MDM2), a cell cycle regulator, is widely expressed in renal resident cells including podocytes. Here, we explore whether MDM2 is involved in podocyte MC during hyperglycaemia...

Diabetic nephropathy (DN) is one of the most common and lethal microvascular complications of diabetes. This study aimed to explore whether coenzymeQ10 (CoQ10) as an antioxidant combined with ultrasound-targeted microbubble destruction (UTMD) could reverse the progress of early diabetic nephropathy (DN). CoQ10 has great potential to treat early DN. However, the clinical application of CoQ10 has been limited because of its low aqueous solubility and non-specific distribution. Therefore, CoQ10-loaded liposomes (CoQ10-lip) were prepared and combined with ultrasound microbubbles for the early theranostics of DN...

The aim of this study was to evaluate the effects of sarpogrelate hydrochloride (SH), a selective serotonin 2A receptor antagonist, on diabetic nephropathy in a type 2 diabetes mouse model. We treated db/m and db/db mice with SH (30 mg/kg/day) for 12 weeks. Rat renal proximal tubule cells (NRK-52E) and mouse macrophages (Raw 264.7) were stimulated by high glucose (30 mM glucose) or LPS (100 ng/ml) with or without SH (20 μM). We found that SH treatment increased serum adiponectin level and decreased urinary albumin, macrophage infiltration to glomeruli, and renal inflammatory and fibrosis signals, which were highly expressed in diabetic mice...

Catheter-related infections in peritoneal dialysis (PD) remain a significant complication, and some patients with recurrent exit-site (ESI) and/or tunnel infections may experience external cuff extrusion. In these cases, cuff-shaving has been described as a possible course of treatment. During a 4-year period, there were 44 patients with PD at our department; all received double-cuffed Tenckhoff catheters. Six (13%) never started on PD. Five (13%) of the 38 active PD patients experienced cuff extrusion. Causes of end-stage renal disease (ESRD) were diabetic nephropathy (n = 1), toxic nephropathy (n = 1), hypertensive nephrosclerosis (n = 1), systemic disease (n = 1) and one with unknown cause...

Macrophage infiltration has been linked to the pathogenesis of diabetic nephropathy (DN). However, how infiltrating macrophages affect the progression of DN is unknown. Although infiltrating macrophages produce pro-inflammatory mediators and induce apoptosis in a variety of target cells, there are no studies in podocytes. Therefore, we tested the contribution of macrophages to podocytes apoptosis in DN. in vivo experiments showed that apoptosis in podocytes was increased in streptozocin (STZ)-induced diabetic rats compared with control rats and that this apoptosis was accompanied by increased macrophages infiltration in the kidney...

Diabetic nephropathy (DN), a common complication associated with both type I and type II diabetes mellitus (DM), is a major cause of chronic nephropathy and a common cause of end-stage renal diseases (ESRD) throughout the world. This study is aimed to determine whether dencichine (De) can ameliorate renal damage in high-glucose-and-fat diet combined STZ (streptozocin) induced DN in type II DM rats and to investigate the potential underlying mechanisms. Markers of metabolism, diabetes, and renal function, and levels of extracellular matrix (ECM) collagen I (Col I), collagen IV (Col IV), fibronectin (FN) and laminin (LN), and of proteins in the TGF-β/Smad pathway were analysed through RT-PCR, western blot, immunofluorescence and immunohistochemistry...

Diabetic nephropathy (DN) is one of the major causes of end-stage renal disease. Nod-like receptors nucleotide-binding domain and leucine-rich repeat pyrin-3 domain (NLRP3) inflammasome displays a considerable role in the chronic inflammatory state observed in diabetic patients. Urinary heat shock protein 72 (uHSP72) is a sensitive and specific biomarker for the early detection of acute kidney injury. The aim of this study was to evaluate NLRP3 relative gene expression, its correlation with inflammatory and oxidative stress markers, and to assess the value of uHSP72 in the early detection of DN in type 2 diabetic patients with different degrees of DN...

The antidiabetic properties and anti-inflammatory effects of Danzhi Jiangtang Capsules (DJC) have been demonstrated in clinical and laboratory experiments. In this study, we explored whether DJC can ameliorate advanced glycation end products- (AGEs-) mediated cell injury and the precise mechanisms of DJC in treating diabetic nephropathy (DN). Western blot analysis was employed to assess the expressions of iNOS, COX2, and SOCS and the phosphorylation of JAK2, STAT1, and STAT3 in glomerular mesangial cells (GMCs) after treatment with DJC...

Paeoniflorin is an effective Chinese traditional medicine with anti-inflammatory and immune-regulatory effects. The aim of this study was to investigate the underlying renoprotective mechanism of Paeoniflorin. In vivo, db/db mice were intraperitoneally injected with Paeoniflorin at a dose of 15, 30, or 60 mg/kg respectively. The immunostaining of TLR2, TLR4, CD68, NF-kB p65 and the mRNA level of inflammatory factors, together with the protein expression of TLR2/4 signaling were evaluated. Our data demonstrated that Paeoniflorin could decrease the urinary albumin excretion rate and inhibit macrophage infiltration and activation through blockage of the TLR2/4 signaling pathway compared with the db/db group in vivo...

Epidermal growth factor receptor (EGFR) has been implicated in the pathogenesis of diabetic nephropathy and renal fibrosis; however, the causative role of sustained EGFR activation is unclear. Here, we generated a novel kidney fibrotic mouse model of persistent EGFR activation by selectively expressing the EGFR ligand, human heparin-binding EGF-like growth factor (HB-EGF), in renal proximal tubule epithelium. Human HB-EGF expression increased tyrosine kinase phosphorylation of EGFR and the subsequent activation of downstream signaling pathways, including ERK and AKT, as well as the profibrotic TGF-β1/SMAD pathway...
