Columnaris disease (CD) caused by Flavobacterium columnare (F. columnare) is lack of knowledge on effective treatment measures. Bacterial pathogens require iron as an essential nutrient to infect the host. While hepcidin acts as a master regulator in iron metabolism, its contribution to host defense is emerging as complex and multifaceted. In vitro, recombinant Ctenopharyngodon idellus (C. idellus) hepcidin (CiHep) and synthetic CiHep both showed the ability to increase the expression of hepcidin and ferritin in C...

Chronic alcoholism is a risk factor for kidney injury. Clonidine is an α 2 -adrenergic receptor/imidazoline-1 receptor agonist that can reduce blood pressure and maintain renal functions. This study aims to investigate the possible ameliorative effects of clonidine on ethanol induced kidney injury and its mechanism of action. Kidney injury was induced in rats by adding ethanol to drinking water for eight weeks. Clonidine effects on kidney functions and histopathology were measured. Moreover, phentolamine (α-adrenergic receptor antagonist), efaroxan (imidazoline-1 receptor antagonist) and rilmenidine (imidazoline-1 receptor agonist) were used to clarify the role of imidazoline-1 receptor in mediating renal ameliorative effects...

REVIEW
Savitha Subramanian, Irl B Hirsch
PURPOSE OF REVIEW: Diabetes is the leading cause of kidney disease globally. Diabetic kidney disease (DKD) is a heterogeneous disorder manifested as albuminuria and/or decreasing GFR. Hyperglycemic burden is the major contributor to the development of DKD. In this article, we review the evidence for the contribution of glycemic variability and the pitfalls associated with use of hemoglobin A1c (A1C), the gold standard for assessment of glucose control, in the setting of DKD. RECENT FINDINGS: Glycemic variability, characterized by swings in blood glucose levels, can result in generation of mitochondrial reactive oxygen species, a putative inciting factor for hyperglycemia-induced alterations in intracellular metabolic pathways...

Apoptosis and autophagy are harmoniously regulated biological processes for maintaining tissue homeostasis. AMP-activated protein kinase (AMPK) functions as a metabolic sensor to coordinate cellular survival and function in various organs, including the kidney. We investigated the renoprotective effects of cinacalcet in high-glucose treated human glomerular endothelial cells (HGECs), murine podocytes and C57BLKS/J-db/db mice. In cultured HGECs and podocytes, cinacalcet decreased oxidative stress and apoptosis and increased autophagy that were attributed to the increment of intracellular Ca 2+ concentration and the phosphorylation of Ca 2+ /calmodulin-dependent protein kinase kinaseβ (CaMKKβ)-Liver kinase B1 (LKB1)-AMPK and their downstream signals including the phosphorylation of endothelial nitric oxide synthase (eNOS) and increases in superoxide dismutases and B cell leukemia/lymphoma 2/BCL-2-associated X protein expression...

Rhabdomyolysis is a condition in which damaged muscle tissue breaks down and intracellular contents, including myoglobin, are released into the circulation. This produces a nonspecific clinical syndrome including electrolyte disturbances, hypovolemia, metabolic acidosis, coagulopathies, and risk of acute kidney injury. Rhabdomyolysis has been reported as a complication of prolonged surgical procedures but has rarely been reported in the oral and maxillofacial surgery literature. Early diagnosis and treatment of rhabdomyolysis are important to avoid long-term complications such as renal failure...

Diabetic kidney disease (DKD) is one of the major complications of diabetes mellitus (DM) and is currently the most common cause of end-stage renal disease (ESRD) worldwide. Traditionally, DKD is considered a disease which has nothing to do with the immune system, and the pathogenesis is mainly characterized to be metabolic disturbance. Recent growing evidence indicates immunologic and inflammatory mechanisms in the development and progression of DKD. This overview of macrophages, dendritic cells, T lymphocytes, B lymphocytes, neutrophils and mast cells is closely involved in the pathologic process of DKD, with more emphasis on the leucocyte accumulation and related molecular mechanisms...

Alkaline phosphatases (APs) remove the phosphate (dephosphorylation) needed in multiple metabolic processes (from many molecules such as proteins, nucleotides, or pyrophosphate). Therefore, APs are important for bone mineralization but paradoxically they can also be deleterious for other processes, such as vascular calcification and the increasingly known cross-talk between bone and vessels. A proper balance between beneficial and harmful activities is further complicated in the context of chronic kidney disease (CKD)...

Recent FDA Drug Safety Communications report an increased risk for acute kidney injury in patients treated with the gliflozin class of sodium/glucose co-transport inhibitors indicated for treatment of type 2 diabetes mellitus. To identify a potential rationale for the latter, we used an in vitro human renal proximal tubule epithelial cell model system (RPTEC/TERT1), physiologically representing human renal proximal tubule function. A targeted metabolomics approach, contrasting gliflozins to inhibitors of central carbon metabolism and mitochondrial function, revealed a double mode of action for canagliflozin, but not for its analogs dapagliflozin and empagliflozin...

Currently, the prevention and treatment of hypertensive crises especially when it occurs with serious adverse outcomes have led to worldwide controversy. Despite of clinical possibilities of multiple agents, clinical failures still occur frequently. Therefore, early evaluations and observations of different therapies on appropriate animals should be emphasized. In the present study, an animal model for hypertensive crises emergencies was firstly established and experimentally testified. Five-month-male spontaneously hypertensive rat was consecutively fed with 60%-Kcal fat diet for four, six, and eight weeks with body weight and blood pressure monitored every two weeks, and then followed by an acute vasoconstriction stress of 5-min ice-bath treatment in the 4-h time interval of two adrenaline injections (0...

BACKGROUND/AIMS: Both iron deficiency and chronic inflammation are highly prevalent in patients with chronic kidney disease (CKD). The effect of intravenous iron infusion on mineral metabolism in CKD may be modified by inflammation. Intravenous iron theraphy may reduce peripheral degradation, secretion, clearence of iFGF23 and lead to hypophosphatemia. The aim of the study was to evaluate the effect of intravenous iron on mineral metabolism in CKD patients. METHODS: 35 non-dialysis patients with CKD stages 3-5...

Chronic kidney disease-mineral and bone disorder (CKD-MBD) is a complex disease which is associated with alterations of bone and mineral metabolism. miR-223 is implicated in both vascular calcification and osteoporosis. In the present study, we investigated the influence of Stab1 gene on miRNA-223 expression in osteoclastogenesis. Differentiation of monocyte/macrophage precursors was assessed by using RAW264.7 cells and peripheral blood mononuclear cells (PBMC). TRAP activity and bone resorption were used to measure osteoclast activity...

Osteoporosis and fragility fractures are important social and economic problems worldwide and are due to both the loss of bone mineral density and sarcopenia. Indeed, fragility fractures are associated with increased disability, morbidity and mortality. It is known that a normal calcium balance together with a normal vitamin D status is important for maintaining well-balanced bone metabolism and for many years calcium and vitamin D has been considered crucial in the prevention and treatment of osteoporosis...

Deregulated lipid metabolism is a characteristic of metabolic diseases including type 2 diabetes and obesity, and likely contributes to podocyte injury and end-stage kidney disease. Heart-type fatty acid binding protein (H-FABP) was reported to be associated with lipid metabolism. The present study investigated whether H-FABP contributes to podocyte homeostasis. Podocytes were transfected by lentiviral vector to construct a cell line which stably overexpressed H-FABP. Small interfering RNA capable of effectively silencing H-FABP was introduced into podocytes to construct a cell line with H-FABP knockdown...
