Attaining and maintaining optimal "dry weight" is one of the principal goals during maintenance hemodialysis (MHD). Recent studies have shown a close relationship between Na load and serum vascular endothelial growth factor-C (VEGF-C) levels; thus, we aimed to investigate the role of VEGF-C as a candidate biomarker of hypervolemia. Physical examination, basic laboratory tests, N-terminal pro b-type natriuretic peptide (NT-ProBNP), echocardiography, and bioimpedance spectroscopy data of 3 groups of study subjects (euvolemic MHD patients, healthy controls, and hypervolemic chronic kidney disease [CKD] patients) were analyzed...

INTRODUCTION: Recipients of conventional hemodialysis (CHD; 3-4 h/session, 3 times/week) experience volume expansion and nutritional impairment which may contribute to high mortality. Prolongation of sessions with in-centre nocturnal hemodialysis (INHD; 7-8 h/session, 3 times/week) may improve clinical outcomes by enhancement of ultrafiltration and uremic toxin removal. MATERIALS AND METHODS: In this prospective cohort study, 56 adult patients who were receiving maintenance CHD for at least 90 days were assigned to CHD (patients who remained in CHD) and INHD (patients who switched to INHD) groups...

In dialysis patients, electrocardiogram (ECG) abnormalities are common. However, the associations between the T-wave of the lead aVR (aVRT) amplitude and cardiovascular (CV) events or total mortality are unknown. We performed a prospective, observational cohort study of prevalent hemodialysis patients (N = 474), followed for 4 years. Outcomes were composite CV events and all-cause mortality. Predictors were baseline aVRT and other ECG findings. ECG parameters were analyzed in three models: model 1, univariate; model 2, basic adjustments; and model 3, model 2 plus serum albumin, C-reactive protein level, and NT-proBNP...

Protein-energy wasting (PEW) is common in hemodialysis (HD) patients. A recent study demonstrated that a high level of N-terminal pro-B-type natriuretic peptide (NT-proBNP) may be associated with PEW in those patients. This prospective study aimed to assess the association of NT-proBNP with body composition and muscle loss. A cohort of prevalent HD patients (n = 238) was examined. Blood samples were obtained at baseline to measure high-sensitive C-reactive protein (hsCRP), interleukin-6 (IL-6), adiponectin and NT-proBNP...

UNLABELLED: End-stage renal disease is a major clinical and public health problem, and cardiovascular disease accounts for half of the mortality in hemodialysis patients. An existing mortality risk score (AROii score) or N-terminal pro-brain natriuretic peptide (NT-proBNP) level have modest predictive power, but there is room for improvement. There are emerging cardiac biomarkers (soluble isoforms of ST2 [sST2], galectin-3 [Gal-3]), and uremic toxicity (indoxyl sulfate). We sought to determine whether these biomarkers predict cardiovascular outcomes in hemodialysis patients and have incremental prognostic value over the clinical score and NT-proBNP level...

OBJECTIVES: Plasma levels of copeptin, a surrogate marker for the vasoconstrictor hormone arginine vasopressin (AVP), are increased in hemodialysis patients. Presently, it is unknown what drives copeptin levels in hemodialysis patients. We investigated whether the established physiological stimuli for copeptin release, i.e. plasma osmolality, blood volume and mean arterial pressure (MAP), are operational in hemodialysis patients. METHODS: One hundred and eight prevalent, stable hemodialysis patients on a thrice-weekly dialysis schedule were studied during hemodialysis with constant ultrafiltration rate and dialysate conductivity in this observational study...
