BACKGROUND The use of lung ultrasonography to evaluate extravascular lung water and its consequences has received growing attention in different clinical areas, including, in recent years, end-stage renal disease patients treated by haemodialysis (HD). Lung congestion is a direct consequence of either overall overhydration and/or cardiac dysfunction, but(More)
Plasma endocan levels are elevated in a large number of diseases, and may reflect endothelial cell dysfunction. There are currently no data on endocan in patients with chronic kidney disease (CKD). Therefore, we measured plasma endocan in 251 patients with CKD (stage 1-5) and 60 control individuals. Plasma endocan concentrations correlated with estimated(More)
Studies comparing survival in hemodialysis (HD) or peritoneal dialysis (PD) patients reported controversial results, mainly during the first 2 years of treatment. Moreover, there is a significant geographic variation in the use of these modalities. We aimed to compare the survival of HD and PD patients using data from the Romanian Renal Registry. In an(More)
BACKGROUND The chronic kidney disease (CKD)-mineral and bone disorder (MBD) syndrome is an important contributor to the CKD-associated cardiovascular disease and high mortality rates. Sclerostin, a protein synthesized in osteocytes, is a potent downregulator of bone metabolism and a novel candidate for the bone-vascular axis in CKD patients. We tested(More)
Although procalcitonin (PCT) has been described as a marker of infection and inflammation, it has not been extensively studied in patients with chronic kidney disease (CKD), end stage renal disease, or renal transplant. PCT was routinely tested in 82 (56 dialyzed patients and 28 renal transplant recipients) consecutive cases with a strong clinical suspicion(More)
BACKGROUND/AIMS The clinical utility of the new biomarker, high sensitivity cardiac T troponin (hs-cTnT) is still unclear in dialysis patients. Furthermore, the prognostic value of combining N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) and hs-cTnT has not been explored so far. The objective of this pilot study was to determine the utility of(More)
BACKGROUND Haemodiafiltration (HDF), by successfully removing the larger solutes and protein-bound compounds, may offer a feasible approach to improve dialysis outcomes. Recently, three large, randomized, controlled trials have tested this hypothesis, but only one showed an improved survival associated with HDF treatment, when compared with haemodialysis(More)
BACKGROUND AND OBJECTIVES Chronic subclinical volume overload occurs very frequently and may be ubiquitous in hemodialysis (HD) patients receiving the standard thrice-weekly treatment. It is directly associated with hypertension, increased arterial stiffness, left ventricular hipertrophy, heart failure, and eventually, higher mortality and morbidity. We(More)
Advanced glycation end products (AGE), biomarkers of metabolic stress, are frequently encountered in chronic kidney disease (CKD) patients with cardiovascular disease. Our aim was to evaluate tissue accumulation of AGEs in CKD patients and possible correlations with traditional and non-traditional cardiovascular risk factors. Skin AF was measured using AGE(More)
Early morning blood pressure surge (MBPS) is a risk factor for cardiovascular events (CVEs), but the relationship with uric acid is not well understood. The authors aimed to determine the association between MBPS and increased uric acid and the effect of elevated MBPS and uric acid combination on CVEs. A total of 921 patients underwent 24-hour ambulatory(More)
