Intravenous immunoglobulin (IVIG) and/or plasmapheresis (PP) are effective in preventing antibody-mediated rejection (AMR) of kidney allografts, but AMR is still a problem. This study reports our experience in living donor renal transplantation in highly sensitized patients. Ten patients with positive crossmatch tests or high levels of panel-reactive(More)
This study evaluated the significance of aortic calcification index (ACI), an estimate of abdominal aortic calcification by plain abdominal computed tomography (CT), in terms of left ventricular (LV) diastolic dysfunction, mortality, and nonfatal cardiovascular (CV) events in chronic hemodialysis patients. Hemodialysis patients who took both an abdominal CT(More)
OBJECTIVE In this study, we investigated the predictive capacity of the brachial-ankle aortic pulse wave velocity (baPWV), a marker of arterial stiffness, for the decline in renal function and for cardiovascular events in the early stages of chronic kidney disease (CKD). METHOD Two hundred forty-one patients who underwent a comprehensive check-up were(More)
BACKGROUND/AIMS The efficacy and safety of a combination of ezetimibe and low-dose statin as primary treatment for dyslipidemia in renal transplant patients were evaluated prospectively. METHODS The study enrolled 77 renal transplant recipients with dyslipidemia. They were given ezetimibe (10 mg) and simvastatin (10 mg) for 6 months as the initial(More)
BACKGROUND/AIMS Kidney transplantations at our center rely mainly on living donors. The purpose of this study was to suggest future donor supply directions by reviewing changing trends in donor type. METHODS During the past 40 years, 1,690 kidney transplantations were performed at our center. We divided the follow-up period into four decades and the donor(More)
Red blood cell distribution width (RDW) is a robust marker of adverse clinical outcomes in various populations. However, the clinical significance of a progressive rise in RDW is undetermined in end-stage renal disease (ESRD) patients. The purpose of this study was to determine the prognostic importance of a change in RDW in ESRD patients. Three hundred(More)
BACKGROUND Rifampin is one of the most important drugs in first-line therapies for tuberculosis. The renal toxicity of rifampin has been reported sporadically and acute tubulointerstitial nephritis (ATIN) is a frequent histological finding. We describe for the first time a case of ATIN and Fanconi syndrome presenting as hypokalemic paralysis, associated(More)
The urachus or median umbilical ligament is a fibrous cord structure that forms after obliteration of the urogen-ital sinus and allantois during normal embryogenesis. A partial or total defect in obliteration of the urachus after 5 months of gestation can cause an ura-chal anomaly, which is usually discovered in childhood. Urachal diseases are rarely(More)
Residual kidney function (RKF) contributes to improved survival in hemodialysis (HD) patients. However, it is not clear whether RKF allows a comparable survival rate in patients undergoing twice-weekly HD compared with thrice-weekly HD.We enrolled 685 patients from a prospective multicenter observational cohort. RKF and HD adequacy was monitored regularly(More)
BACKGROUND AND AIM Patients with chronic kidney disease (CKD) often have subclinical hypothyroidism. However, few reports have investigated changes in the status of subclinical hypothyroidism in CKD patients and its clinical significance in CKD progression. METHODS We included 168 patients with nondialysis-dependent CKD stages 2-4. The normalization of(More)
