AIM Atherosclerotic cardiovascular disease is one of the major causes of mortality and morbidity in peritoneal dialysis (PD) patients. S100A12 is an endogenous receptor ligand of advanced glycation end-products. It was shown to contribute to the development of atherosclerosis in animal models. The aim of this study was to evaluate the relationship between(More)
BACKGROUND Fibroblast growth factor 23 (FGF-23) is a phosphorus-regulating hormone. In chronic kidney disease (CKD), circulating FGF-23 levels are markedly elevated and independently associated with mortality. Left ventricular hypertrophy (LVH) is a potent risk factor for mortality in CKD, and FGFs have been implicated in the pathogenesis of myocardial(More)
BACKGROUND Hypervolemia is a major risk factor for hypertension leading to cardiovascular diseases and also a frequent problem in maintenance hemodialysis (MHD) patients. Fluid overload (FO) can be determined by bioimpedance spectroscopy (BIS) which is a new, practical, and non-invasive method. We tried to determine FO by BIS in MHD patients and find out(More)
BACKGROUND Renalase, with possible monoamine oxidase activity, is implicated in degradation of catecholamines; which suggests novel mechanisms of cardiovascular complications in patients with chronic kidney diseases. Epicardial adipose tissue (EAT) has been found to correlate with cardiovascular diseases (CVD) in dialysis patients. The present study aimed(More)
AIM Upper gastrointestinal bleeding (UGIB) is a very frequently encountered condition that has a high morbidity and which increases treatment costs. Duration of hospital stay and mortality increases in patients with UGIB complicated by acute kidney injury (AKI). The aim of this study was to reveal risk factors in patients with UGIB developing AKI and to(More)
INTRODUCTION Antibody-mediated rejections (AMRs) are critical clinical issues encountered in short- and long-term follow-up of kidney transplant patients. Whereas plasmapheresis is a mainstay treatment option in acute AMR cases, there is a paucity of data regarding its efficacy in management of chronic AMR. This report describes our experience addressing(More)
Encapsulating peritoneal sclerosis (EPS) is an occasional and serious complication for peritoneal dialysis (PD) patients for whom no evidence-based management strategies have yet been established. Encapsulating peritoneal sclerosis could appear after kidney transplantation in patients who previously underwent long-term PD. In this report, we present our(More)
Nefrologia 2013;33(6):849-67 861 Dear Editor, The chronic use of immunosuppressive agents is associated with the long-term risk of a wide variety of malignancies, including Kaposi’s sarcoma (KS), in renal transplant recipients compared with those of the general population. KS occurs after transplantation of 5 to 21 months and more commonly in males. The(More)
Atherosclerotic cardiovascular disease is an important cause of mortality and morbidity in hemodialysis patients. Iron accumulation in arterial wall macrophages is increased in atherosclerotic lesions. Hepcidin is a key hepatic hormone regulating iron balance. It inhibits iron release from macrophages and iron absorption from enterocytes by binding and(More)
