Diabetes is the leading cause of chronic kidney disease. Prognostic biomarkers reflective of underlying molecular mechanisms are critically needed for effective management of diabetic kidney disease (DKD). In the Clinical Phenotyping and Resource Biobank study, an unbiased, machine learning approach identified a three-marker panel from plasma proteomics which, when added to standard clinical parameters, improved the prediction of outcome of end-stage kidney disease (ESKD) or 40% decline in baseline glomerular filtration rate (GFR) in a discovery DKD group (N=58) and was validated in an independent group (N=68) who also had kidney transcriptomic profiles available. Of the three markers, plasma angiopoietin 2 (ANGPT2) remained significantly associated with composite outcome in 210 Chinese Cohort Study of Chronic Kidney Disease participants with DKD. The glomerular transcriptional Angiopoietin/Tie (ANG-TIE) activation scores, derived from the expression of 154 literature-curated ANG-TIE signaling mediators, positively correlated with plasma ANGPT2 levels and outcome, explained by substantially higher TEK receptor expression in glomeruli and higher ANG-TIE activation scores in endothelial cells in DKD by single cell RNA sequencing. Our work suggests that activation of glomerular ANG-TIE signaling in the kidneys underlies the association of plasma ANGPT2 with disease progression, thereby providing potential targets to prevent DKD progression.

Diabetes is the leading cause of end-stage kidney failure throughout the world in both developed and developing countries.' The same is now true of Kashmir Valley also. In a study conducted in 1999 amongst 780 patients of chronic kidney disease in the only nephrology unit of the Valley, chronic glomerulonephritis was the commonest cause of chronic kidney disease constituting 33% of the total number.2 But a decade latter in another study diabetes was the leading cause of chronic kidney disease and accounting for 33.3% of the total number.It is very important to alert doctors, patients and govern-ments to the increasing health and socioeconomic problems due to diabetic kidney disease and its sequelae (1) end stage kidney disease requiring renal replacement therapy, and (2) cardio-vascular death. There is a horrifying lack of awareness of diabetic kidney disease at all levels and we need to emphasize that its management involves prevention, recognition and treatment of its complications. Primary prevention of type 2 diabetes will require massive life-style changes. J Med Sci.2010;13(1);1-3

Abstract Diabetic kidney disease develops in about 40% of patients with diabetes and is the commonest cause of chronic kidney disease worldwide. Patients with chronic kidney disease, especially those with diabetes mellitus, are at high risk of both developing kidney failure and cardiovascular death. The use of renin-angiotensin system blockers to reduce the incidence of kidney failure in patients with diabetic kidney disease dates back to studies that are now 20 or more years old. During the last few years sodium-glucose co-transporter-2 inhibitors have shown beneficial renal effects in randomized trials. However, even in response to combined treatment with renin-angiotensin system blockers and sodium-glucose co-transporter-2 inhibitors, the renal residual risk remains high with kidney failure only deferred, but not avoided. The risk of cardiovascular death also remains high even with optimal current treatment. Steroidal mineralocorticoid receptor antagonists reduce albuminuria and surrogate markers of cardiovascular disease in patients already on optimal therapy. However, their use has been curtailed by the significant risk of hyperkalaemia. In The FInerenone in reducing kiDnEy faiLure and dIsease prOgression in Diabetic Kidney Disease (FIDELIO-DKD) study comparing the actions of the non-steroidal mineralocorticoid receptor antagonist finerenone with placebo, finerenone reduced the progression of diabetic kidney disease and the incidence of cardiovascular events with a relatively safe adverse event profile. This document presents in detail the available evidence on the cardioprotective and nephroprotective effects of mineralocorticoid receptor antagonists, analyses the potential mechanisms involved and discusses their potential future place in the treatment of patients with diabetic chronic kidney disease.

Phosphorus Intake

Phosphorus is an essential nutrient that is critically important in the control of cell and tissue function and body homeostasis. Phosphorus excess may result in severe adverse medical consequences. The most apparent is an impact on cardiovascular (CV) disease, mainly through the ability of phosphate to change the phenotype of vascular smooth muscle cells and its contribution to pathologic vascular, valvular and other soft tissue calcification. Chronic kidney disease (CKD) is the most prevalent chronic disease manifesting with the persistent derangement of phosphate homeostasis. Diabetes and resulting diabetic kidney disease (DKD) remain the leading causes of CKD and end-stage kidney disease (ESRD) worldwide. Mineral and bone disorders of CKD (CKD-MBD), profound derangement of mineral metabolism, develop in the course of the disease and adversely impact on bone health and the CV system. In this review we aimed to discuss the data concerning CKD-MBD in patients with diabetes and to analyze the possible link between hyperphosphatemia, certain biomarkers of CKD-MBD and high dietary phosphate intake on prognosis in patients with diabetes and DKD. We also attempted to clarify if hyperphosphatemia and high phosphorus intake may impact the onset and progression of DKD. Careful analysis of the available literature brings us to the conclusion that, as for today, no clear recommendations based on the firm clinical data can be provided in terms of phosphorus intake aiming to prevent the incidence or progression of diabetic kidney disease.

Diabetic kidney disease (DKD) is a global epidemic leading to end-stage renal disease (ESRD) and susceptibility to cardiovascular disease, with few therapeutic interventions. A hallmark of DKD is the activation of the renin-angiotensin-aldosterone system and hemodynamic changes in glomerulus. Although intensive therapy with agents that targets those abnormalities lowers the risk of DKD progression, it does not completely abolish the risk of ESRD and cardiovascular events. Recent studies have illustrated the importance of renal inflammation, oxidative stress, and activated Rho-associated protein kinase (ROCK) signaling as essential pathogenesis for the development of DKD. In this commentary, these topics will be discussed.

Diabetic nephropathy is increasing in incidence and is now the number one cause of end-stage renal disease in the industrialized world. To gain insight into the genetic susceptibility and pathophysiology of diabetic nephropathy, an appropriate mouse model of diabetic nephropathy would be critical. A large number of mouse models of diabetes have been identified and their kidney disease characterized to various degrees. Perhaps the best characterized and most intensively investigated model is the db/ db mouse. Because this model appears to exhibit the most consistent and robust increase in albuminuria and mesangial matrix expansion, it has been used as a model of progressive diabetic renal disease. In this review, we present the findings from various studies on the renal pathology of the db/ db mouse model of diabetes in the context of human diabetic nephropathy. Furthermore, we discuss shortfalls of assessing functional renal disease in mouse models of diabetic kidney disease.

Diabetic kidney disease (DKD) is defined as a clinical syndrome consisting of persistent macroalbuminuria, progressive decline in glomerular filtration rate (GFR), hypertension, increased cardiovascular disease events, and the associated mortality of these conditions. The disease evolves from the microvascular complications of poorly controlled Type 1 diabetes mellitus (T1DM) and Type 2 diabetes mellitus (T2DM). The pathogenic pathways comprise renal haemodynamic changes, ischaemia and inflammation, and overactive renin–angiotensin–aldosterone system (RAAS), through which several events cascade down from hyperglycaemia to renal fibrosis. Conventional and novel renoprotective strategies target modifiable DKD risk factors and specific stages of the pathogenic pathways, respectively. Although these strategies may slow DKD progression to end-stage kidney disease (ESKD), novel drugs are still undergoing trials for validation in human participants. This narrative review appraises these renoprotective strategies and highlights the current clinical staging and pathogenesis of the disease.

End Stage

Diabetic kidney disease (DKD) is a known complication of diabetes mellitus that increases patients’ risks of developing end-stage renal failure requiring dialysis treatment and vulnerability of fatal outcomes resulted from cardiovascular events. Therefore, a good diabetic control among patients with DKD is essential. Nevertheless, monitoring glycaemia in DKD is very challenging. The use of the gold standard glycaemic marker, haemoglobin A1c (HbA1c), is complicated by many hindrances associated with both biochemical and physiological derangements of DKD. Despite the constraints, the Kidney Disease Improving Global Outcome has recommended the use of HbA1c as a reliable glycaemic marker in DKD patients, whose estimated glomerular filtration rate is down to 30 millilitres/minute per 1.73 meter2 . In this article, we discuss the reliability and limitations of HbA1c as an advocated glycaemic marker in DKD. Considering that the reliability of HbA1c is highly dependent on the interpretation of the results, we also highlighted the common potential factors that can affect HbA1c interpretation in patients with DKD. The article also discusses the issues related to the utility of glycated albumin and serum fructosamine as alternative glycaemic biomarkers, and continuous glucose monitoring as a complementary marker to HbA1c in clinical practice. Understanding the HbA1c values and their limitations is important to ensure accurate interpretation of glycaemic status and to achieve optimal diabetic control in patients with DKD.
