The recent discoveries in the fields of pathogenesis and management of diabetic nephropathy have revolutionized the knowledge about this disease. Little was added to the management of diabetic nephropathy after the introduction of renin angiotensin system blockers. The ineffective role of the renin- angiotensin system blockers in primary prevention of diabetic nephropathy in type 1 diabetes mellitus necessitated the search for other early therapeutic interventions that target alternative pathogenic mechanisms...

IgA nephropathy (IgAN) is the most common primary glomerulonephritis in developed countries and a leading cause of chronic kidney disease. IgAN is a mesangial proliferative glomerulonephritis characterized by diffuse mesangial deposition of IgA, often accompanied by the deposition of IgG and the C3 component of complement in a similar distribution. This condition is in most cases oligosymptomatic, often discovered coincidentally. Currently, there is no specific treatment available for IgAN and the use of immunosuppression therapy is debated...

BACKGROUND/AIMS: Renal tubular epithelial-mesenchymal transition (EMT) is regarded as an important factor leading to renal interstitial fibrosis. Erythropoietin (EPO) has been reported to attenuate renal fibrosis. The mechanism underlying this protective effect of EPO remains unclear. In this study, we aim to identify possible mechanisms of the EPO renoprotective effect. METHODS: Hypoxia was induced in vitro by incubating human proximal tubular epithelial cell line HK-2 cells in 1% O2 and 5% CO2...

PURPOSE: Podocyte injury is a key event in proteinuric kidney disease and eventually glomerular scarring. While adrenomedullin (AM), a potent vasodilatory peptide, has been reported to confer renoprotection in several experimental models of kidney diseases, its effect on injured podocytes and the related mechanism is still largely unknown. METHODS: Employing Western blotting analysis, immunoprecipitation and immunofluorescence, we investigated the effects of AM on the expressions of podocyte cytoskeletal proteins and Rho-family small GTPases (Rho GTPases) in puromycin aminonucleoside (PAN)-induced podocyte injury, both in cultured podocytes and in PAN nephrosis rats...

There is increasing evidence that sodium glucose cotransporter 2 (SGLT2) inhibitors have renoprotective effects, as demonstrated by the renal analyses from clinical trials including Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients-Removing Excess Glucose (EMPA-REG OUTCOME), CANagliflozin Treatment And Trial Analysis versus SUlphonylurea (CANTATA-SU), and the dapagliflozin renal study. The potential mechanisms responsible are likely multifactorial, and direct renovascular and hemodynamic effects are postulated to play a central role...

Diabetic nephropathy (DN) is a major cause of end-stage renal disease (ESRD) worldwide. Glycemic and blood pressure (BP) control are important but not sufficient to attenuate the incidence and progression of DN. Sodium-glucose cotransporter (SGLT) 2 inhibitors are a new class of glucose-lowering agent suggested to exert renoprotective effects in glucose lowering-dependent and independent fashions. Experimental studies have shown that SGLT2 inhibitors attenuate DN in animal models of both type 1 diabetes (T1D) and type 2 diabetes (T2D), indicating a potential renoprotective effect beyond glucose reduction...

OBJECTIVE: Several clinical studies have shown the beneficial effects of peroxisome proliferator-activated receptor α (PPARα) agonists on diabetic nephropathy. However, the molecular mechanism is not fully understood. Here we show that K-877, a novel selective PPARα modulator, ameliorates nephropathy in db/db mice via inhibition of renal lipid content and oxidative stress. METHODS AND RESULTS: K-877 (0.5mg/kg/day) was administered to db/db mice for 2 or 12weeks...

PURPOSE OF REVIEW: Despite optimal therapy of diabetic nephropathy with agents blocking the renin-angiotensin-aldosterone system, the residual risk of nephropathy progression to end-stage renal disease (ESRD) remains high. The purpose of this review is to discuss the potential role of endothelin antagonism as a therapeutic tool to reduce residual proteinuria and delay kidney injury progression among patients with diabetic nephropathy. RECENT FINDINGS: Preclinical studies have shown that endothelin receptor antagonists (ERAs) exert proteinuria lowering and nephroprotective actions in experimental models of diabetic nephropathy...

Salvianolic acid B (SAB) is one the major phytocomponents of Radix Salvia miltiorrhiza and exhibit numerous health promoting properties. The objective of the current study was to examine whether SAB exerts a renoprotective effect by attenuating oxidative stress and inflammatory response through activating phosphatidylinositol 3-kinase/serine-threonine kinase B (PI3K/Akt) signaling pathway in a renal ischemic reperfusion rat model. Forty Sprague-Dawley male rats (250-300 g) were obtained and split into four groups with ten rats in each group...

Diabetic kidney disease (DKD) is the most common cause of end stage renal disease. The comprehensive management of DKD depends on combined target-therapies for hyperglycemia, hypertension, albuminuria, and hyperlipaemia, etc. Sodium-glucose co-transporter 2 (SGLT2) inhibitors, the most recently developed oral hypoglycemic agents acted on renal proximal tubules, suppress glucose reabsorption and increase urinary glucose excretion. Besides improvements in glycemic control, they presented excellent performances in direct renoprotective effects and the cardiovascular (CV) safety by decreasing albuminuria and the independent CV risk factors such as body weight and blood pressure, etc...

We report the case of a 34-year-old Japanese male with lipoprotein glomerulopathy (LPG). Renal biopsy showed LPG, and followed by a genetic analysis revealed a mutation in apolipoprotein E gene (APOE Kyoto; Arg25Cys). We started treatment with probucol, bezafibrate, losartan, and allopurinol. Urinary protein decreased in response to treatment but has remained at about 1.27 ± 0.71 g/gCr, and a repeat biopsy which was performed 1 year after the first biopsy showed no clear evidence of pathological remission and complication of other glomerular disease...

Preconditioning is the premise that controlled preemptive exposure to sub-lethal doses of a stressor and can condition an organism or organ to later withstand a lethal dose. This process relies on marshaling endogenous survival resources that have evolved as part of an organism's evolutionary struggle to overcome at times harsh environmental conditions. This preconditioning response occurs through activation of myriad complex mechanisms that run the gamut from alterations in gene expression to the de novo synthesis and post-translational modification of proteins, and it may occur across exposure to a wide variety of stressors (i...

Most chronic nephropathies progress relentlessly to end-stage kidney disease. Research in animals and humans has helped our understanding of the mechanisms of chronic kidney disease progression. Current therapeutic strategies to prevent or revert renal disease progression focus on reduction of urinary protein excretion and blood pressure control. Blockade of the renin-angiotensin system (RAS) with angiotensin-converting enzyme inhibitors and/or angiotensin II type 1 receptor blockers is the most effective treatment to achieve these purposes in non-diabetic and diabetic proteinuric renal diseases...
