Responsiveness to erythropoietin-stimulating agent (ESA) may be associated with mortality risk in hemodialysis (HD) patients. The aim of the present study was to assess the relationship between responsiveness to ESA and long-term outcome in chronic HD patients. Patients on HD therapy for more than 6 months were enrolled in this cohort study. The first year(More)
Objective: Alkaline phosphatase (ALP) is considered a biomarker of high bone turnover in hemodialysis (HD) patients with secondary hyperparathyroidism. This study was conducted to determine whether high serum ALP levels are associated with increased all-cause mortality of HD patients. Patients and Methods: This was a retrospective cohort study conducted at(More)
BACKGROUND New bone metabolic markers have become available clinically for evaluating chronic kidney disease mineral and bone disorders (CKD-MBD). The aim of this study was to correlate these new bone metabolic markers with conventional markers in regular hemodialysis (HD) patients. METHODS One hundred forty three HD patients underwent cross-sectional(More)
Lanthanum carbonate (LC) is one of the relatively new phosphate binders. The general LC dosage form is a chewable pharmaceutical preparation. This investigation was targeted to subjects who do not chew LC chewable preparations adequately, for the purpose of studying the clinical efficacy of changing to pulverized prescriptions, such as changes in serum(More)
Paediatric kidney transplantation has different aspects in adults in terms of underlying primary renal disease, surgical technique, perioperative care and graft prognosis. Significant urological problems are present in a high percentage of paediatric recipients. This study was undertaken to characterize paediatric kidney transplantation as performed at our(More)
Diabetic nephropathy is the most common cause of chronic kidney disease. We investigated the ability of intracellular galectin-1 (Gal-1), a prototype of endogenous lectin, to prevent renal fibrosis by regulating cell signaling under a high glucose (HG) condition. We demonstrated that overexpression of Gal-1 reduces type I collagen (COL1) expression and(More)
OBJECTIVE An enlarged left atrium (LA) has recently been identified as a risk factor for adverse cardiovascular outcomes in various pathologic conditions. However, few studies have evaluated its prognostic value in hemodialysis (HD) patients. METHODS We conducted an observational study to investigate whether an enlarged LA predicted all-cause mortality in(More)
Osteocalcin (OC) is a known bone metabolic marker and a regulator of glucose and fat metabolisms. Although bone and energy metabolisms are known risk factors for cardiovascular disease (CVD) in hemodialysis (HD) patients, few studies have examined the correlation between OC and CVD. The purpose of this study was to investigate the impact of serum OC levels(More)
We report a 59-year-old woman with AL amyloidosis who presented with massive bleeding from the right kidney, in whom emergency surgery proved to be life saving. The patient had been diagnosed as having AL amyloidosis 16 years previously. After 5 years, hemodialysis had been initiated. In 2007, a large right-sided perinephric, intracapsular hematoma was(More)
OBJECTIVE Orthostatic hypotension during a hemodialysis (HD) session affects not only the modality but daily quality of life for HD patients because many of them have combined dysfunction of both sympathetic and parasympathetic nervous systems. Although various non-invasive methods have been applied for the evaluation of autonomic function, no monitor has(More)
