BACKGROUND: There is little data on the incidence of diabetes complications in young onset type 1 diabetes (T1DM) and type 2 diabetes (T2DM) in non European populations. METHODS: From a tertiary diabetes centre, Chennai, India, we recruited 108 T1DM (defined by abrupt onset of symptoms or diabetic ketoacidosis, absent insulin reserve requiring insulin treatment) and 90 T2DM participants (defined by absence of ketosis, good beta-cell reserve, and good response to oral agents) who were diagnosed between the ages of 10 and 25years, and without any evidence of diabetes complications at diagnosis...

Statins, 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase inhibitors have been shown to improve diabetic nephropathy. However, whether they provide protection via Histone deacetylases (HDAC) inhibition is not clear. We conducted a comparative evaluation of Atorvastatin (AT) versus the non-statin cholesterol-lowering drug, Ezetimibe (EZT) on severity of diabetic nephropathy. Streptozotocin-treated male Wistar rats were fed a cholesterol-supplemented diet and gavaged daily with vehicle, AT or EZT. Control rats received normal diet and gavaged vehicle (n = 8-9/group)...

Diabetic nephropathy (DN) is one of the most serious microvascular complications of diabetes mellitus and the leading cause of end stage renal disease. One of the key pathways activated in DN is the polyol pathway, in which glucose is converted to sorbitol (a relatively non-metabolizable sugar) by the enzyme aldose reductase (AR). Shunting of glucose into this pathway causes disruption to glucose metabolism and subsequently damages the tissues via increased oxidative stress, protein kinase c activation and production of advanced glycation end products (AGE) in the kidney...

BACKGROUND: Patients with chronic kidney disease (CKD) undergoing coronary angiography (CA), adequate hydration and minimizing volume of contrast media (CM) are class 1b recommendations for preventing contrast induced nephropathy (CIN). Current data are insufficient to justify specific recommendations about isoosmolar vs. low-osmolar contrast media by the ACCF/AHA/SCAI guidelines. METHODS: Randomized trials comparing IOCM to LOCM in CKD stage 3 and above patients undergoing CA, and reporting incidence of CIN (defined by a rise in creatinine of 25% from baseline) were included in the analysis...

BACKGROUND: Diabetic nephropathy (DN) is a major complication of type1 and type 2 diabetes. Understanding how diabetes regulate transcriptome dynamics in DN is important for understanding the biology of the disease and for guiding development of new treatments. RESULTS: We analyzed the kidney transcriptome of a DN mouse model, D2.B6-Ins2 (Akita) /MatbJ, before/after treatment with P78-PEDF. Age, weight, and gender-matched mice and wild-type (wt) littermates were treated at 6 weeks (early treatment) or 12 weeks (late treatment) of age for the duration of 6 weeks...

Diabetic nephropathy (DN) is the leading cause of kidney failure in the world. To understand important mechanisms underlying this condition, and to develop new therapies, good animal models are required. In mouse models of type-1 diabetes, the DBA/2J strain has been shown to be more susceptible to develop kidney disease than other common strains. We hypothesized this would also be the case in type-2 diabetes. We studied db/db and wt DBA/2J mice and compared these with the db/db BLKS/J mouse, which is currently the most widely used type-2 DN model...

Saturated fatty acid (SFA)-related lipotoxicity is a pathogenesis of diabetes-related renal proximal tubular epithelial cell (PTEC) damage, closely associated with a progressive decline in renal function. This study was designed to identify a free fatty acid (FFA) metabolism-related enzyme that can protect PTECs from SFA-related lipotoxicity. Among several enzymes involved in FFA metabolism, we identified stearoyl-CoA desaturase-1 (SCD1), whose expression level significantly decreased in the kidneys of high-fat diet (HFD)-induced diabetic mice, compared with non-diabetic mice...

Chronic kidney disease (CKD) is much more common than people recognize, and habitually goes undetected and undiagnosed until the disease is well advanced or when their kidney functions is down to 25% of normal function. Genetic and non-genetic factors contribute to cause CKD. Non-genetic factors include hypertension, High level of DNA damage due to the production of reactive oxygen species and nucleic acid oxidation has been reported in CKD patients. Main genetic factor which causes CKD is diabetic nephropathy...

Diabetic nephropathy (DN) is a major cause of morbidity and mortality in diabetic patients and a leading cause of end-stage renal disease (ESRD). Degenerative changes such as glomerular hypertrophy, hyperfiltration, widening of basement membranes, tubulointerstitial fibrosis, glomerulosclerosis and podocytopathy manifest in various degrees of proteinuria in DN. One of the key mechanisms implicated in the pathogenesis of DN is non-enzymatic glycation (NEG). NEG is the irreversible attachment of reducing sugars onto free amino groups of proteins by a series of events, which include the formation of Schiff's base and an Amadori product to yield advanced glycation end products (AGEs)...

AMP-activated protein kinase is a family of heterotrimeric serine/threonine protein kinases that come in twelve different flavors. They serve an essential function in all eukaryotes of conserving cellular energy levels. AMPK complexes are regulated by changes in cellular AMP:ATP or ADP:ATP ratios and by a number of neutraceuticals and some of the widely-used diabetes medications such as metformin and thiazolinonediones. Moreover, biochemical activities of AMPK are tightly regulated by phosphorylation or dephosphorylation by upstream kinases and phosphatases respectively...

Oxidative stress contributes to the pathogenesis of diabetic nephropathy (DN). Nuclear factor erythroid 2-related factor 2 (NRF2) plays a key role in cellular defense against oxidative stress. NRF2 activators have shown promising preventive effects on DN. Sodium butyrate (NaB) is a known activator of NRF2. However, it is unknown whether NRF2 is required for NaB protection against DN. Therefore, streptozotocin-induced diabetic C57BL/6 Nrf2 knockout and their wild-type mice were treated in the presence or absence of NaB for 20 weeks...

Transplantation is the optimal choice for renal replacement therapy in patients with autosomal dominant polycystic kidney disease (ADPKD). However, some specific issues should be addressed before transplantation, including nephrectomy of native kidneys, cystic liver involvement, screening for intracranial aneurysms and living related-donor transplantation. After kidney transplantation, patient and graft survival rates are excellent and the size of native kidneys typically declines. Nevertheless, a number of renal and extrarenal complications have been documented in kidney transplant recipients with ADPKD...

The current categorization of chronic kidney disease (CKD) is based on biomarkers of the glomerular function (estimated glomerular filtration rate, eGFR) and injury (urinary albumin creatinine ratio, UACR) and provides information on the risk of death and of progression of kidney disease. However, there are gaps in knowledge regarding the risk stratification of elderly patients with eGFR 45-60 ml/min/1.73 m2 and of younger patients with higher eGFR but physiological albuminuria. In this regard, most of the kidney cell mass is composed of tubules...

BACKGROUND: Diabetic nephropathy (DN) is a late complication in both type 1 diabetes mellitus (T1DM) and T2DM. Already at an early stage of DN morphological changes occur at the cell surface and in the extracellular matrix where the majority of the proteins carry N-linked glycosylations. These glycosylated proteins are highly important in cell adhesion and cell-matrix processes but not much is known about how they change in DN or whether the distinct etiology of T1DM and T2DM could have an effect on their abundances...

OBJECTIVE: Nicotinamide phosphoribosyltransferase (Nampt) cooperates with a longevity gene, Sirt1, to exert the potentiation of stress resistance. We have reported that the high expression level of Nampt in PTs contributes to the sufficient supply of NMN to glomeruli. We also showed that downregulation of Nampt and NMN in PT in DN leads to glomerular damages (Nature Medicine 2013). However, the regulation mechanisms of Nampt expression remain unknown. DESIGN AND METHOD: We investigated how Nampt expression is consistently retained at high levels in PTs under normal conditions and how Nampt levels are decreased in DN...

There is accumulating evidence that RAS inhibitors not only reduce blood pressure, but also exert pleiotropic effects, including a renoprotective effect, amelioration of insulin resistance, reduction in onset of diabetes, and suppression of cardiovascular remodelling,. However, the definite benefit of RAS inhibition in treatment of hypertension with CKD or DM is not conclusive. We previously performed the OlmeSartan and Calcium Antagonists Randomized (OSCAR) study comparing the preventive effect of high-dose ARB therapy versus ARB plus CCB combination therapy on cardiovascular morbidity and mortality in 1164 Japanese elderly hypertensive patients with baseline type 2 diabetes and/or CVD (Am J Med (2012))...

OBJECTIVE: We have previously reported the genetic determinants of unmet renal needs in Type 2 Diabetic (T2D) patients of the ADVANCE study (Abstract 0105-PD, IDF - World Diabetes Congress, Vancouver, 2015). We report here the external validation of several of these loci. An improved knowledge of the genetics linked to worsening diabetic nephropathy will offer insights on how to better manage this complication of diabetes and hypertension in T2D patients. DESIGN AND METHOD: We investigated 3,500 T2D patients of Caucasian origin included in the ADVANCE trial who were all treated with current standard therapies...
