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 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)
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 Diagnosis of acute kidney injury (AKI) has been a major concern due to its association with increased morbidity and mortality. However, the clinical implication of the urine output criterion (UOCr) in diagnosing AKI has not been fully established. METHODS We assessed the incidence of AKI among 1625 critically ill patients and analysed the(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)
The circulating white blood cell (WBC) count has been considered a good biomarker of systemic inflammation, but the predictive value of this inexpensive and universally obtained test result has not been fully explored in the elderly. The objective of this study was to assess the independent association of WBC count and its individual components with(More)
To characterize the association between chronic kidney disease (CKD), mortality, severity of coronary artery disease (CAD), treatment modality of CAD, and type of coronary stents among patients undergoing coronary angiography (CAG), we retrospectively reviewed the electronic medical records of the patients who underwent CAG at Seoul National University(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)
Previous studies reported the beneficial effect of erythropoietin (EPO) in acute injuries. We followed patients with and without acute kidney injury (AKI) after coronary artery bypass grafting (CABG) and evaluated the effect of EPO on long-term outcome. We also assessed the efficacy of urinary neutrophil gelatinase-associated lipocalin (uNGAL) as a(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)
