Increased plasma S-nitrosothiol levels in chronic haemodialysis patients.
BACKGROUND An impairment of nitric oxide (NO) bioavailability and/or metabolism may contribute to the excessive incidence of atherosclerotic complications observed in haemodialysis (HD) patients. Recent evidence indicates that NO metabolism involves a family of NO-related molecules that have not yet been explored in such patients. The aim of our study was to determine the plasma levels of S-nit...
متن کاملPlasma ghrelin levels in patients undergoing haemodialysis and peritoneal dialysis.
BACKGROUND Ghrelin has been characterized as a relevant physiologic regulator of appetite and body weight in humans. However, the potential relationships between ghrelin levels, inflammation and malnutrition in dialysis patients have not been adequately studied. METHODS We used a cross-sectional design to study 20 haemodialysis (HD) and 21 peritoneal dialysis (PD) patients, and compared their...
متن کاملThe influence of hepatitis C and iron replacement therapy on plasma pentosidine levels in haemodialysis patients.
BACKGROUND Chronic liver disease and intravenous (i.v.) iron therapy can enhance oxidative stress. The aim of this study was to assess the influence of hepatitis C virus (HCV) and i.v. iron administration on oxidative stress in chronic haemodialysis (HD) patients. METHODS A total of 115 HD patients (47% males, age 47 +/- 13 years) were placed in two groups according to the presence (HCV(+)) o...
متن کاملInappropriately high plasma leptin levels in obese haemodialysis patients can be reduced by high flux haemodialysis and haemodiafiltration.
1. Blood leptin levels are increased in obese subjects and seem to play a major role in the hypothalamic regulation of appetite and energy expenditure. 2. We measured plasma leptin levels in a cohort of 46 patients on maintenance haemodialysis treatment and 26 control subjects. 3. Higher body mass indices were associated with higher plasma leptin levels in both groups. 4. The increase was more ...
متن کاملPlasma levels of mature form of adrenomedullin in patients with haemodialysis.
BACKGROUND Adrenomedullin (AM) is a potent vasodilator and natriuretic peptide with hypotensive effects. Immunoreactive AM in human plasma consists of the biologically active mature form, AM (1-52)-CONH2 (mAM) and the intermediate form, AM-gly-COOH (iAM). However, the different effects of mAM and iAM in patients on haemodialysis (HD) have remained unclear. METHODS Thirty-nine patients on HD a...
