Adverse changes in nutrition are prevalent and are strong indicators of adverse outcomes in patients with chronic kidney disease (CKD). The International Society of Renal Nutrition and Metabolism (ISRNM) proposed a common nomenclature and diagnostic criteria to identify protein-energy wasting (PEW) in CKD patients. We examined the nutritional status in 1,834 adults with predialysis CKD enrolled in the KoreaN cohort study for Outcome in patients With Chronic Kidney Disease (KNOW-CKD) study. As th

OBJECTIVE: Previous cross-sectional studies suggest an association between low muscle mass and hypertension. However, whether low muscle mass predicts the development of hypertension is unknown. The aim of this study is to investigate the relationship between relative muscle mass and incident hypertension in a large prospective cohort of Korean adults. METHODS: In this prospective cohort study, we analyzed 132 324 participants without hypertension at baseline who underwent two health check-ups i

Background: Studies have suggested that the serum creatinine/cystatin C (Cr/CysC) ratio is a surrogate marker for muscle wasting is associated with adverse outcomes in several disease conditions. To clarify the utility of the Cr/CysC ratio as a prognostic marker in chronic kidney disease (CKD) we evaluated the association between the Cr/CysC ratio clinical outcomes in patients with non-dialysis CKD. Methods: This prospective observational cohort study included 1,966 participants of the KoreaN co

T-cell dysregulation plays an important role in the pathogenesis of immunoglobulin A nephropathy (IgAN). Adipose-derived stem cells (ASCs) have been reported to be able to prevent tissue damage through immune-modulating effects. To evaluate the effects of ASCs in high IgA ddY (HIGA) mice, ASCs were isolated from HIGA mice with different stages of IgAN before and after disease onset. ASCs were injected at a dose of 5×10(6) cells/kg body weight through the tail vein every 2 weeks for 3 months. Alt

Abstract Background The independent association between eGFR and coronary artery calcification (CAC) is complex and not clear. The aim of this study was to investigate the relationship between eGFR calculated from different equations and CAC in predialysis CKD patients in Korea. Methods In this cross‐sectional study, we analysed 1533 patients from the KNOW‐CKD cohort. eGFR was calculated by a four‐variable MDRD equation (eGFR MDRD ), CKD‐EPI creatinine equations (eGFR Cr ), CKD‐EPI cystatin C eq

BACKGROUND/AIMS: Both arterial stiffness and coronary artery calcification (CAC) are important predictors of cardiovascular disease in the general population and in chronic kidney disease (CKD) patients. Recent studies on arterial stiffness and CAC in subjects with preserved renal function have verified the association between the two. However, the relationship is not well evaluated in CKD patients. METHODS: This cross-sectional study analyzed 1,385 predialysis CKD patients from the KNOW-CKD coh

Abstract Aim Previous studies have shown that fenofibrate improves outcomes such as albuminuria and estimated glomerular filtration rate decline. We hypothesize that fenofibrate has renoprotective effects and prevents or delays the development of end‐stage renal disease. The objective of this study is to investigate the risk of incident end‐stage renal disease in relation to fenofibrate treatment in patients who are already taking statins. Materials and Methods We performed a nationwide populati

High serum FGF23 was associated with CAC in CKD patients with high adiponectin, but not in those with low adiponectin. Further studies are warranted to verify the role of adiponectin in FGF23-related CAC.
