OBJECTIVE To study the effect of fondaparinux, a new antithrombotic agent, as an anticoagulant during a 4-hour conventional hemodialysis session. materials and methods: Fondaparinux was administered as an anticoagulant to 16 chronic hemodialysis patients during a single 4-hour hemodialysis session at an intravenous bolus dose of 2.5 mg. Eight patients were(More)
To study and compare the anticoagulant activity of enoxaparin sodium during on-line hemodiafiltration (OL-HDF) and conventional hemodialysis (C-HD). Enoxaparin was administered as an anticoagulant to 21 hemodialysis patients at the beginning of a single 4-hour OL-HDF session as an intravenous bolus dose of 80 IU/kg [DOSAGE ERROR CORRECTED] On-line(More)
BACKGROUND Many regimens using different doses of folic acid (FA) alone or with supplementation of B-complex vitamins (BCV) have been tested for the reduction of total homocysteine (tHcy) levels in hemodialysis (HD) patients. BCV are usually administered orally and for a short period. In the present study, we assessed the effect of long-term intravenous(More)
In the present retrospective study we report our 10-year experience with therapeutic plasma exchange (TPE) in 18 patients with grade 2-3 hematopoietic stem cell transplantation (HSCT)-associated thrombotic thrombocytopenic purpura (TTP). During TPE a mean total quantity of 26.5 +/- 15.1 L of plasma was exchanged. Five patients (27.7%) had a complete(More)
The anticoagulant effects of two LMWHs, tinzaparin sodium and bemiparin sodium, were compared during two study dialysis (SD) sessions (SD1 with tinzaparin and SD2 with bemiparin) in ten chronic hemodialysis patients. Prior to SD1, patients had received 3,500 IU of tinzaparin in each dialysis session for two weeks. After SD1, they were switched to 3,500 IU(More)
We report a new and simple way that can reveal the presence of vascular access recirculation (VAR) in patients undergoing hemodialysis (HD). Acid-base and blood gas parameters (pH, pO(2), pCO(2), and HCO(3)) were measured in blood samples drawn from an arterial fistula needle before the initiation of HD and from arterial and venous lines simultaneously 5(More)
Blood returning from a dialyzer during hemodialysis has a higher pO2 and pCO2 content than blood entering the dialyzer, and this has been attributed to the dialysate. The present study investigates this phenomenon. Acid-base and blood-gas parameters (pH, pO2, pCO2 and HCO3) were measured in three groups of stable chronic hemodialysis patients (A, B, and C)(More)
AIM This study aimed to describe our experience with the use of uncuffed double-lumen silicone hemodialysis catheters (USHDCs) that were used in 54 cases as a temporary vascular access (VA). SUBJECTS AND METHODS We recorded, retrospectively, all the USHDCs (size 13.5 French (F), length 15, 20 and 24 cm) that were inserted in our dialysis unit from July(More)
