Fibroblast growth factor 23 (FGF23) is a phosphate-regulating hormone that acts primarily on the kidney and parathyroid. With declining kidney function there is an increase in circulating FGF23 levels, which is associated with vascular calcification and mortality in chronic kidney disease. Whether FGF23 exerts direct effects on vasculature is unclear. We(More)
A 58-year-old woman presented with muscle weakness, whole body myalgia, and dyspnea. On admission, neurological examination showed proximal muscle weakness in the extremities. The weakness gradually extended to the bulbar and respiratory muscles, necessitating an artificial ventilator. Serum CK level was markedly increased (33,774 IU/L; normal <150 IU/L)(More)
Neutrophils are central players in the innate immune system. They generate neutrophil extracellular traps (NETs), which protect against invading pathogens but are also associated with the development of autoimmune and/or inflammatory diseases and thrombosis. Here, we report that lactoferrin, one of the components of NETs, translocated from the cytoplasm to(More)
It is widely known that salt is an accelerating factor for the progression of metabolic syndrome and causes cardiovascular diseases, most likely due to its pro-oxidant properties. We hypothesized that excessive salt intake also facilitates the development of nonalcoholic steatohepatitis (NASH), which is frequently associated with metabolic syndrome. We(More)
A 64-yr-old man with end-stage kidney disease caused by hypertensive nephrosclerosis underwent living-unrelated ABO-identical kidney transplantation (KTx) at the age of 60 yr from his 60-yr-old wife. Maintenance trough concentration of cyclosporine A (CsA) was 100 ± 30 ng/mL. Five months after KTx, proteinuria gradually increased to around 1 g/d. TRBx at(More)
Aldosterone plays an important role in regulating Na-Cl reabsorption and blood pressure. Epithelial Na+ channel, Na+-Cl- cotransporter, and Cl-/HCO3- exchanger pendrin are the major mediators of Na-Cl transport in the aldosterone-sensitive distal nephron. Existing evidence also suggests that plasma K+ concentration affects renal Na-Cl handling. In this(More)
Genome-wide analysis of renal sodium-transporting system has identified specific variations of Mendelian hypertensive disorders, including HSD11B2 gene variants in apparent mineralocorticoid excess. However, these genetic variations in extrarenal tissue can be involved in developing hypertension, as demonstrated in former studies using global and(More)
Acquired cystic kidney disease (ACKD) is a well-known late stage complication of chronic kidney disease. Cysts tend to grow with time on dialysis and could lead to malignant transformation, and intra- or perirenal hemorrhage is a rare complication of ACKD. Here we describe one case of bilateral spontaneous perirenal hemorrhage of ACKD in a 44-year-old man,(More)
