BACKGROUND Statins reduce the incidence of cardiovascular events in patients at high cardiovascular risk. However, a benefit of statins in such patients who are undergoing hemodialysis has not been proved. METHODS We conducted an international, multicenter, randomized, double-blind, prospective trial involving 2776 patients, 50 to 80 years of age, who(More)
BACKGROUND Depression is the most common psychological complication and may increase mortality in chronic hemodialysis patients. Because depression could be associated with poor oral intake and activation of proinflammatory cytokines that could further increase mortality by malnutrition, we investigated the relation between depression and nutritional status(More)
BACKGROUND/AIMS Depending on the specific definition, acute kidney injury (AKI) occurs in 7-40% of patients undergoing cardiac surgery. Even small changes in serum creatinine (SCr) levels are associated with increased mortality after cardiac surgery. However, there are no current methods for preventing AKI after cardiac surgery. Erythropoietin (EPO) has(More)
Oxidative stress plays various roles in the development and progression of IgA nephropathy, while bilirubin is known as a potent antioxidant. We therefore hypothesized that serum bilirubin would be associated with renal prognosis in IgA nephropathy. The study subjects comprised 1,458 adult patients with primary IgA nephropathy in Korea. We grouped patients(More)
AIM The usefulness of renal pathologic diagnosis in type II DM (diabetes mellitus) remains debate. METHODS We grouped the pathologic diagnoses as pure DN (diabetic nephropathy), NDRD (non-diabetic renal disease), and NDRD mixed with DN (Mixed). We classified pure DN as the criteria suggested by Tervaert. We compared the accuracy of clinical parameters to(More)
BACKGROUND The phospholipase A(2) receptor (PLA2R) is a major antigen found in patients with idiopathic membranous nephropathy (MN). The relationship of genetic polymorphisms of PLA2R with the susceptibility and clinical outcomes of this disease is unknown. METHODS We studied 199 patients with idiopathic MN followed up for 3.7 ± 3.2 years. We enrolled 33(More)
BACKGROUND Bilirubin (BIL) has been recognized as an endogenous antioxidant that shows a protective effect for cardiorenal diseases. We investigated whether administration of BIL had a protective effect on cyclosporine (CsA)-induced nephropathy (CIN), and examined the effects of BIL on the oxidative stress and apoptosis. METHODS BIL was pretreated(More)
BACKGROUND Chronic hypoxia in the kidney has been suggested as a final common pathway to end-stage renal disease. Hypoxia-inducible factor (HIF) is a transcription factor that regulates cellular hypoxic responses, and it is a promising target with therapeutic potential in various kidney disease models. In this study, we investigated whether HIF activation(More)
Gentamicin nephrotoxicity is one of the most common causes of acute kidney injury (AKI). Hypoxia-inducible factor (HIF) is effective in protecting the kidney from ischemic and toxic injury. Increased expression of HIF-1α mRNA has been reported in rats with gentamicin-induced renal injury. We hypothesizd that we could study the role of HIF in(More)
BACKGROUND The incidence of chronic kidney disease (CKD) is increasing in Korea, especially in the aged population. The health-related quality of life (HRQOL) of patients with chronic renal insufficiency is lower than that for the general population and a lower HRQOL is a predictor of adverse events. We report the impact of kidney function on the HRQOL and(More)
