Background: Mortality in patients with stages 4 and 5 chronic kidney disease (CKD) is higher than in the general population. Body composition predicts mortality. Our objective was to evaluate the effect of body composition on mortality in patients with stages 4 and 5 non-dialysis CKD. Methods: We performed a prospective study of 356 patients with stages 4 and 5 non-dialysis CKD. At baseline, we...

BACKGROUND Adequacy of body fluid volume improves short- and long-term outcomes inpatients with heart and kidney disorders. Bioelectrical impedance vector analysis (BIVA) has the potential to be used as a routine method at the bedside for assessment and management of body fluids. METHODS Impedance (Z vector) is a combination of resistance, R (function of intra- and extracellular fluid volume)...

The aim of this study was to determine the kinetics of H(2)18O equilibration and elimination in preterm babies for the estimation of total body water. Thirteen, clinically stable, preterm babies of less than 32 weeks' gestation were studied in the first week after birth. Blood and urine samples were obtained for baseline measurement of 18O:16O ratio and 1 ml/kg of 10% H(2)18O (0.1 g/kg isotope)...

INTRODUCTION Fluid overload is one of the most important, yet modifiable, risk factors associated with worse outcomes in hemodialysis (HD) patients. However, its precise assessment in clinical practice is still under investigation. MATERIAL AND METHODS This is an observational prospective study which included 285 stable patients with end-stage renal disease on standard thrice-weekly HD therap...

Abstract Background and Aims Peritoneal Dialysis (P.D.) Adequacy includes a variety of targets such as the sufficient uremic toxins removal (Κt/V), patients’ euvolemia, acid-base electrolyte balance etc.. Based on incremental PD prescription NIPD is often reasonable modality choice when there adequate Residual Renal Function (RRF). Eventually due to RRF decrease patients need increase their ade...

Background Disturbances in sexual function are common among dialysis patients. Normal erections require a complex balance of physiological, psychological, emotional, hormonal, neurological and vascular factors. This study examined a possible association of overhydration (OH) with male sexual dysfunction and depression in hemodialysis (HD) patients. Patients and methods This cross-sectional st...

The aim of this study was to detect the potential occurrence of early abnormalities of body composition in patients with chronic kidney disease (CKD) at first referral to an outpatient nephrology clinic. Eighty-four patients with CKD (49 men and 35 women) were compared with 604 healthy control subjects (298 men and 306 women). Anthropometry and bioelectrical impedance analysis (BIA) were perfor...

BACKGROUND Observational studies have demonstrated an association between anemia and adverse outcomes in patients with chronic kidney disease (CKD). However, randomized trials failed to identify a benefit of higher hemoglobin concentrations, suggesting that the anemia-outcome association may be confounded by unknown factors. METHODS AND RESULTS We evaluated the influence of fluid status on he...
