BACKGROUND/AIMS: Kidney function is critical for homocysteine (Hcy) clearance, and plasma Hcy levels are frequently increased in patients with renal failure. Microalbuminuria (MAU) is an important marker of early renal damage caused by hypertension. At present, there is insufficient evidence on the relationship between Hcy and microalbuminuria. METHODS: This is a 1: 2 matched, hospital-based case-control study. At initial visit, out of 1535 outpatients with no prior history of medication, 450 qualified subjects were selected based on inclusion and exclusion criteria...

BACKGROUND/AIMS: Protein energy wasting (PEW) is a common medical phenomenon that is observed in maintenance dialysis patients. PEW also increases morbidity and mortality of these patients. Its pathogenesis is unclear. We hypothesize that serum irisin levels and volume overload may induce PEW in peritoneal dialysis (PD) patients. The aim of this study is to measure serum irisin levels, evaluate volume status of PD patients, and study their correlations with PEW in PD patients. METHODS: This study is a cross-sectional study with 160 PD patients from the PD center of Peking University Third Hospital and 35 healthy control subjects...

BACKGROUND/AIMS: Hemodialysis induces an intravascular inflammatory reaction which may further deteriorate renal function. We studied changes of serum interleukin 6 (IL6) and hepatocyte growth factor (HGF) concentrations during dialysis sessions, and at 12 month intervals. The synthesis of these cytokines in arterial endothelial cells in the presence of serum obtained from dialyzed patients was studied. Changes of the inflammatory reaction during 12 months of treatment were correlated with GFR...

BACKGROUND/AIMS: Hyperphosphatemia is one of the most notable features of chronic kidney disease (CKD). Numerous epidemiological and clinical studies have found that high serum phosphate concentrations are associated with calcification in the coronary arteries. However, the mechanisms underlying the vascular calcification induced by high phosphate have not been understood fully. METHODS: Vascular smooth muscle cells (VSMCs) were cultured in high-phosphate media to induce vascular calcification, which was detected by Alizarin red S staining...

BACKGROUND/AIMS: Post-transplant hypertension is highly prevalent in renal transplant recipients and is a risk factor for graft loss, cardiovascular disease and death. Glucocorticoid is used to prevent rejection, but simultaneously increases the risk of post-transplant hypertension. The glucocorticoid-induced transcript 1 (GLCCI1) promoter polymorphism (rs37972) has been reported to be associated with response to glucocorticoid therapy in asthma. We therefore examined the association between GLCCI1 promoter polymorphism and post-transplant hypertension in renal transplant recipients...

BACKGROUND/AIMS: The renal resistive index (RI) is a novel candidate as a renal injury prognostic indicator, but it remains unclear how renal RI levels correspond to renal injury in diabetic nephropathy. METHODS: To examine this issue, we compared 8-week-old male C57BL/6 mice fed with high-fat diet (HFD) versus chow diet (CHD) for 16 weeks. At 8 and 12 weeks, the glomerular filtration rate (GFR), urinary albumin-to-creatinine ratio (UACR), and inflammatory factors (IL-1β, IL-6, TNFα, and MCP-1) were measured, along with the increase in renal RI...
