The binding to human albumin of fluorescein monoglucuronide, a fluorescent metabolite of fluorescein, was studied using two methods: pressure dialysis and fluorescence polarization. Both methods indicated that fluorescein monoglucuronide binds to human albumin more loosely than fluorescein. The free fraction in human plasma estimated from the dissociation constant and the number of binding site...

INTRODUCTION Vildagliptin can be used in patients with type 2 diabetes mellitus and renal impairment. However, there have been few reports investigating the clinical effectiveness of vildagliptin in diabetic patients undergoing hemodialysis. No previous studies have evaluated the use of vildagliptin in patients undergoing peritoneal dialysis. The authors determined the usefulness of vildaglipti...

The degree of binding of a drug to plasma proteins has a marked effect on its distribution, elimination, and pharmacological effect since only the unbound fraction is available for distribution into extra-vascular space. The protein-binding of atenolol was measured by equilibrium dialysis in the bovine serum albumin (BSA). Free atenolol concentration was increased due to addition of arsenic whi...

Malnutrition inevitably accompanies Chronic Kidney Disease (CKD) and dialysis. Markers of malnutrition like low serum albumin have been shown to correlate independently with higher mortality in dialysis patients (1).Malnutrition is seen in both Hemodiaysis (HD) and Peritoneal Dialysis (PD) patients. The incidence has been described at 10-70% in HD and 1851% in PD patients (2,3). The causes of m...

The binding of several anticandidal peptides containing N3-(4-methoxyfumaroyl)-L-2,3-diaminopropanoic acid (FMDP) to serum proteins was studied using equilibrium dialysis. The affinity of these FMDP-peptides for serum albumin was low and well correlated with their biological activity against Candica albicans ATCC 26278 in serum albumin solution. This binding did not affect the biological activi...

BACKGROUND AND OBJECTIVES Serum albumin is a widely used biomarker of nutritional status in patients with CKD; however, its usefulness is debated. This study investigated serum albumin and its correlation with several markers of nutritional status in incident and prevalent dialysis patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS In a cross sectional study, serum albumin (bromocresol p...

Gel filtration of plasma from hemodialysis patients, with use of reagents and apparatus with carefully minimized background Al concentrations, reproducibly showed a single peak for Al, corresponding exactly to the elution position of transferrin. The Al/transferrin molar ratio in adjacent fractions was constant (mean 0.126, SE 0.006) in replicate experiments. In contrast, the association of Al ...

Background: Cardiovascular diseases including peripheral arterial disease (PAD) are highly prevalent among hemodialysis patients. PAD is one of the important manifestations of systemic atherosclerosis and is related to poorer quality of life among patients with end-stage renal disease (ESRD). In this study, we evaluated the prevalence and correlation factors of PAD in hemodialysis patients usin...

In dialysis patients, C-reactive protein (CRP), a well-recognized marker of inflammation, predicts mortality. Higher levels have been described in hemodialysis (HD) patients as compared with peritoneal dialysis (PD) patients. Our aim was to determine, based on CRP plasma levels, the degree of inflammation in HD patients using low-permeability polysulfone membranes and relatively pure dialysate,...

This paper presents the development of water-permeable dialysis membranes that are suitable for an implantable microdialysis system that does not use dialysis fluid. We developed a microdialysis system integrating microfluidic channels and nanoporous filtering membranes made of polyethersulfone (PES), aiming at a fully implantable system that drastically improves the quality of life of patients...
