BACKGROUND Although there has been considerable investigation of the general characteristics of contrast-induced nephropathy (CIN), it has not been studied adequately in a computed tomography (CT) population. We assessed the incidence and outcomes of CIN after contrast-enhanced CT in patients with chronic kidney disease pretreated with saline and(More)
Endothelial cell damage and impaired angiogenesis substantially contribute to the progression of chronic renal failure (CRF). The effect of endothelial progenitor cell (EPC) treatment on the progression of CRF is yet to be determined. We performed 5/6 nephrectomy to induce CRF in C57BL/6 mice. EPCs were isolated from bone marrow, grown in conditioned(More)
It is known that blood pressure variability (BPV) can independently affect target organ damage (TOD), even with normal blood pressure. There have been few studieson chronic kidney disease (CKD) patients. We evaluated the relationship between BPV and TOD in a cross-sectional, multicenter study on hypertensive CKD patients. We evaluated 1,173 patients using(More)
Race and ethnicity are influential in estimating glomerular filtration rate (GFR). We aimed to find the Korean coefficients for the Modification of Diet in Renal Disease (MDRD) study equations and to obtain novel proper estimation equations. Reference GFR was measured by systemic inulin clearance. Serum creatinine (SCr) values were measured by the alkaline(More)
We evaluated the diagnostic and clinical usefulness of blood specimens to detect Middle East respiratory syndrome coronavirus infection in 21 patients from the 2015 outbreak in South Korea. Viral RNA was detected in blood from 33% of patients at initial diagnosis, and the detection preceded a worse clinical course.
BACKGROUND AND OBJECTIVES The notion that oral intestinal sorbent AST-120 slows renal disease progression has not been evaluated thoroughly. In this study, we investigated the long-term effect of AST-120 on renal disease progression (doubling of serum creatinine, eGFR decrease >50%, or initiation of RRT) in patients with advanced CKD. DESIGN, SETTING,(More)
BACKGROUND/AIMS Angiotensin II has been shown to play an important role in various renal diseases. Genetic polymorphisms of the renin-angiotensin system have been reported to be related to the clinical outcomes in immunoglobulin A nephropathy (IgAN). We investigated the association of polymorphisms of the genes encoding major angiotensin II-forming enzymes(More)
Cardiovascular disease (CVD) is the main public health problem in patients with chronic kidney disease (CKD); however, there is no established biomarker for predicting CVD morbidity and mortality in CKD. The aim of this study was to evaluate the role of circulating tumor necrosis factor receptors (cTNFRs) in predicting CVD risk in CKD patients.We(More)
AIM Although cystatin C has been developed as an alternative marker for estimating glomerular filtration rate (GFR), its clinical use is as yet limited. The significance of cystatin C for differentiating chronic kidney disease (CKD) stages and established cystatin C-based equations estimating GFR were evaluated. METHODS The fresh frozen serum samples from(More)
There is a significant immune response to ischemia-reperfusion injury (IRI), but the role of immunomodulatory natural killer T (NKT) cell subtypes is not well understood. Here, we compared the severity of IRI in mice deficient in type I/II NKT cells (CD1d(-/-)) or type I NKT cells (Jα18(-/-)). The absence of NKT cells, especially type II NKT cells,(More)
