To identify biomarker candidates associated with early IgA nephropathy (IgAN) and thin basement membrane nephropathy (TBMN), the most common causes presenting isolated hematuria in childhood, a proteomic approach of urinary exosomes from early IgAN and TBMN patients was introduced. The proteomic results from the patients were compared with a normal group to(More)
BACKGROUND Human peritoneal mesothelial cells (HPMCs) undergo a transition from an epithelial phenotype to a mesenchymal phenotype (EMT) during peritoneal dialysis (PD). That transition may be directly related to failure of peritoneal membrane function. OBJECTIVE In a randomized prospective controlled study, we investigated the effect of low glucose(More)
BACKGROUND We investigated the effects of gene polymorphisms on the development of IgA nephropathy and thin glomerular basement membrane (GBM) disease by analyzing polymorphisms in the interleukin (IL)-18, transforming growth factor (TGF)-β, and vascular endothelial growth factor (VEGF) genes in Korean patients. METHODS This study included 146 normal(More)
The inhibitory effects of recombinant human erythropoietin (rhEPO) were examined against (1) the progression of renal fibrosis in mice with complete unilateral ureteral obstruction and (2) the TGF-beta1-induced epithelial-to-mesenchymal transition (EMT) in MDCK cells. Unilateral ureteral obstruction was induced in BALB/c mice and rhEPO (100 or 1000 U/kg,(More)
Background Anti-angiotensin II type 1 receptor antibodies (AT1R-Abs) have been suggested as a risk factor for graft failure and acute rejection (AR). However, the prevalence and clinical significance of pretransplant AT1R-Abs have seldom been evaluated in Asia. Methods In this multicenter, observational cohort study, we tested the AT1R-Abs in(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)
BACKGROUND The body metabolism of patients with end-stage renal disease may be altered in response to long-term dialysis treatment. Moreover, the pattern of serum metabolites could change depending on the type of dialysis modality used. However, dialysis modality-dependent changes in serum metabolites are poorly understood. Our aim was to profile(More)
BACKGROUND The impact of dialysis modality on survival is still somewhat controversial. Given possible differences in patients' characteristics and the cause and rate of death in different countries, the issue needs to be evaluated in Korean cohorts. METHODS A nationwide prospective observational cohort study (NCT00931970) was performed to compare(More)
BACKGROUND Interleukin 18 (IL-18) is a potent proinflammatory cytokine, which is postulated to play a role in mechanism of renal allograft rejection and strongly induces interferon (IFN)-gamma production. The aim of this study was to investigate the association of the G-137C IL-18 promoter polymorphism with acute allograft rejection in renal transplant(More)
BACKGROUND/AIMS Encapsulating peritoneal sclerosis (EPS) is an often-fatal complication of long-term peritoneal dialysis (PD). We here report the clinical features of EPS in Korean PD patients from a single university center. METHODS The data were collected retrospectively from 606 PD patients at Kyungpook National University Hospital, between August 2001(More)
