PURPOSE OF REVIEW: Diabetic kidney disease (DKD) is one of the most common complications in diabetes mellitus and accounts for a large proportion of clinical nephrology practice. Studies have shown that the kallikrein-kinin system (KKS) may be involved in several pathogenic mechanisms that contribute to DKD, including oxidative stress, inflammatory cytokines, and profibrotic autacoids. This review focuses on recent research advance on the potential role of the KKS in the development of DKD and its clinical relevance...

Recent antihypertensive trials show conflicting results on blood pressure (BP) targets in patient populations with different metabolic profiles, with lowest benefit from tight BP control observed in patients with type 2 diabetes mellitus. This paradox could arise from the heterogeneity of study populations and underscores the importance of precision medicine initiatives towards understanding and treating hypertension. Wnt signaling pathways and genetic variations in its signaling peptides have been recently associated with metabolic syndrome, hypertension and diabetes, generating a breakthrough for advancement of precision medicine in the field of hypertension...

The antioxidant protein haptoglobin (Hp) plays a major role in the development of diabetic complications such as diabetic nephropathy and retinopathy. In humans, two alleles of Hp were identified: 1 and 2 with three possible genotypes: 1-1, 2-1, and 2-2. The Hp protein products differ in their biochemical and biophysical properties, such as their antioxidant capacity. The Hp1 protein is superior to the Hp2 protein in binding to free hemoglobin and neutralizing its oxidative potential and the accompanying renal and retinal injury...

Orexins (orexin A and orexin B), neuropeptides of hypothalamic origin also known as hypocretins, have been well documented for regulating the different physiological functions including feeding, sleep wakefulness, stress, and reward. However, from the past few years, orexins have evolved as an emerging biomarker for various endocrine disorders including diabetes mellitus and obesity which ultimately leads to various cardiovascular risk factors. Orexins exist in two isoforms orexin A and orexin B and exert their effect by acting on the G protein-coupled receptors orexin 1 receptor (OX1R) and orexin 2 receptor (OX2R)...

It is widely accepted that obesity and type 2 diabetes mellitus (T2DM) increase the risk of heart failure (HF) independently of underlying coronary artery disease. The changes in myocardial structure or function associated with diabetes have been termed diabetic cardiomyopathy. Corresponding to changes in the risk factors for HF, an epidemiologic transition is underway from HF with a reduced ejection fraction to HF with a preserved ejection fraction. Hyperglycemia can damage the myocardium, even before diagnosis of diabetes, but intensive glycemic control has no impact on the risk of HF in patients with T2DM...

Metformin, widely used as first-line treatment for type 2 diabetes, exists primarily as a hydrophilic cation at physiological pHs. As such, membrane transporters play a substantial role in its absorption, tissues distribution, and renal elimination. Multiple organic cation transporters are determinants of the pharmacokinetics of metformin, and many of them are important in its pharmacological action, as mediators of metformin entry into target tissues. Further, a recent genomewide association study (GWAS) in a large multi-ethnic population implicated polymorphisms in SLC2A2, encoding the glucose transporter, GLUT2, as important determinants of response to metformin...

It has previously been demonstrated that nicotinamide adenine dinucleotide phosphate‑oxidase (NADPH) oxidase 4 (Nox4), is important in the pathogenesis of diabetic nephropathy (DN), however the exact mechanisms remain to be elucidated. The present study aimed to examine the effect of Nox4 on the alteration of the Notch pathway and cell apoptosis in the renal tubular epithelial cell line, HKC, under conditions of high glucose (HG; 30 mmol/l glucose). Nox4 and the Notch pathway were inhibited by N‑acetylcysteine (NAC), diphenylene iodonium (DPI) or γ‑secretase inhibitor (DAPT)...

The urotensinergic system was previously considered as being linked to numerous physiopathological states, including atherosclerosis, heart failure, hypertension, pre-eclampsia, diabetes, renal disease, as well as brain vascular lesions. Thus, it turns out that the actions of the urotensin II (UII)/G protein-coupled receptor UT system in animal models are currently not predictive enough in regard to their effects in human clinical trials and that UII analogs, established to target UT, were not as beneficial as expected in pathological situations...

Diabetic nephropathy (DN) is an important diabetic microvascular complication, and it is becoming the leading cause of end-stage renal disease worldwide. Unfortunately, there are no effective therapies to treat established DN. Therefore, new therapeutic targets are urgently required. Accumulating studies indicate that mitochondrial dysfunction is central to the pathogenesis of DN, such as elevated oxidative stress induced by disorders of the mitochondrial respiratory chain complex and mitochondrial dynamic disorders...

A 45-year-old woman with type 1 diabetes and chronic renal failure on dialysis underwent simultaneous pancreas-kidney transplantation from a brain dead donor. On postoperative day 15, acute generalized peritonitis was diagnosed and emergency laparotomy was performed. Perforation of the donor duodenum was found, which had apparently resulted from duodenal compression by the tip of the intestinal fistula tube placed for decompression. The perforation was sutured and the intestinal fistula tube was exchanged. Following this, perforation repeatedly recurred at the same site and open repair at laparotomy was required a total of four times...

Oxidative stress is a consequence of up-regulation of pro-oxidant enzyme-induced reactive oxygen species (ROS) production and concomitant depletion of antioxidants. Elevated levels of ROS act as an intermediate and are the common denominator for various diseases including diabetes-associated macro-/micro-vascular complications and hypertension. A range of enzymes are capable of generating ROS, but the pro-oxidant enzyme family, nicotinamide adenine dinucleotide phosphate (NADPH) oxidases (NOXs), are the only enzymes known to be solely dedicated to ROS generation in the vascular tissues, kidney, aortas and eyes...

Endothelin-1 (ET-1) is the most potent vasoconstrictor, and is involved in the renal regulation of salt and water homeostasis. When produced in excess in the kidney, ET-1 promotes proteinuria and tubulointerstitial injury. There is great interest in the clinical use of endothelin receptor antagonists (ERAs) in chronic kidney disease (CKD), mainly in diabetic nephropathy (DN). Areas covered: Physiopathological actions of ET-1 on the kidney. Both dual ETAR/ETBR (bosentan) or ETAR specific endothelin antagonists (avosentan and atrasentan, among others), which have progressed to early clinical development, with particular emphasis on atrasentan...
