BACKGROUND Use of uncuffed catheters (UCs) in hemodialysis patients is common practice. An antibiotic lock has been recommended to prevent catheter-related bacteremia (CRB), although insufficient data are available about the appropriate antimicrobial agent and dose with prolonged use of UCs. METHODS This open-label randomized study was conducted to(More)
The prevalence and significance of sleep-disordered breathing (SDB) in dialysis-independent chronic renal failure (CRF) remains unknown. We studied the presence of SDB in nondialyzed CRF patients. Diagnostic polysomnography was performed in consecutive stable nondialyzed CRF patients. Inclusion criteria were age <or=70 years, absence of systolic dysfunction(More)
BACKGROUND Active vitamin D is an effective treatment for secondary hyperparathyroidism (SHPT) in chronic kidney disease (CKD) patients often complicated by hypercalcaemia and hyperphosphataemia. Treatment with paricalcitol, a selective vitamin D receptor activator, has shown benefits by adequately reducing parathyroid hormone (PTH) levels with minimal(More)
Morbidity and mortality are markedly elevated in chronic kidney disease (CKD) patients as consequence of cardiovascular risk factors clustering. Non-traditional risk factors such as inflammation are far more prevalent in this population and contribute significantly to atherosclerosis and cardiovascular disease (CVD). CKD results in a chronic, low-grade(More)
Hyperuricemia is particularly common in patients with arterial hypertension, metabolic syndrome, or kidney disease. Its role, however, as a risk factor for both renal and cardiovascular outcomes and in the context of the well-established interrelationship between cardiovascular disease and chronic kidney disease (CKD) is debated. For decades high serum uric(More)
Hepatitis B (HB) in haemodialysis patients results in morbidity and mortality, through chronicity, which leads to cirrhosis and liver carcinoma, even after renal transplantation. Hepatitis B vaccination is protective against HB virus infection. Suppressed immunity in renal failure leads to low HB vaccination success rates. Uremia, inadequate dialysis, use(More)
BACKGROUND/AIMS Depression represents the most frequent psychiatric disorder in nephrology. Cytokines, and especially IL-6, were found to be elevated in depressed patients with normal renal function. The objective of this pilot study was to examine the relationship between depression and cytokines (IL-6, TNF-alpha, and IL-10) in patients with end-stage(More)
Carnitine is an ammo acid derivative found in high energy demanding tissues (skeletal muscles, myocardium, the liver and the suprarenal glands). It is essential for the intermediary metabolism of fatty acids. Carnitine is indispensable for beta-oxidation of long-chain fatty acids in the mitochondria but also regulates CoA concentration and removal of the(More)
BACKGROUND Chronic inflammation and oxidative stress are common features in hemodialysis patients. However, research results on the long-term influence of hemodiafiltration (HDF) on oxidative stress and inflammation are limited. METHODS We studied changes of inflammatory and oxidative stress biomarkers in 9 stable patients on post-dilution HDF for 9(More)
