Diuretic-resistant congestive heart failure in the form of type 2 cardiorenal syndrome is a problem of growing significance in everyday clinical practice because of high morbidity and mortality. There has been scant progress in the treatment of overhydration, the main cause of symptoms in this group of patients. The aim of our review is to present recent advances in the ultrafiltration therapy ...

OBJECTIVES This study was designed to compare the safety and efficacy of veno-venous ultrafiltration and standard intravenous diuretic therapy for hypervolemic heart failure (HF) patients. BACKGROUND Early ultrafiltration may be an alternative to intravenous diuretics in patients with decompensated HF and volume overload. METHODS Patients hospitalized for HF with > or =2 signs of hypervolem...

INTRODUCTION The aim of the study was to evaluate two methods of macroprolactin (MaPRL) detection - precipitation with polyethylene glycol (PEG) and ultrafiltration and to compare these techniques with "gold standard" - gel filtration chromatography (GFC). MATERIAL AND METHODS The study was conducted on 245 patients - 45 with organic and 200 with functional hyperprolactinaemia. In all the sub...

Free thyroxin (FT4) measurements by ultrafiltration were compared with results obtained by equilibrium dialysis and commercial RIA methods. In a group of critically ill patients, the mean +/- 2 SD FT4 value by ultrafiltration (26.5 +/- 21.4 ng/L) was higher than in the healthy reference population (19.3 +/- 9.8 ng/L, p less than 0.0001), and correlated well with equilibrium dialysis (23.8 +/- 2...

Background: Ultrafiltration failure is a significant cause of technique failure for peritoneal dialysis and subsequent transfer to hemodialysis. Summary: Ultrafiltration failure is defined as failure to achieve at least 400 ml of net ultrafiltration during a 4 h dwell using 4.25% dextrose. Four major causes of ultrafiltration failure have been described. A highly effective peritoneal surface ar...

Ultrafiltration using polyethersulfone-membranes was evaluated as an efficient and preferred method for purifying Cowpea Chlorotic Mottle Virus (CCMV). Cesium chloride (CsCl) ultracentrifugation and ultrafiltration protocols are described, and comparative UV-spectroscopic and electron micrograph results are presented. CCMV purified by ultrafiltration are shown to be equivalent to CCMV purified ...

Background: The relative contribution of transcapillary water movement and lymphatic reabsorption in peritoneal dialysis (PD) is a critical issue, particularly in patients with ultrafiltration failure (UFF). Based on routine results obtained from the PD Adequest 2.0 software, the present study aimed to re-evaluate the separate effects of transcapillary water movement and lymphatic reabsorption ...

background: cardiopulmonary bypass is associated with increased fluid accumulation around the heart which influences pulmonary and cardiac diastolic function. the aim of this study was to compare the effects of modified ultrafiltration (muf) versus conventional ultrafiltration (cuf) on duration of mechanical ventilation and hemodynamic status in children undergoing congenital heart surgery.mate...

Hypoallergenic antibacterial low-molecular-mass peptides were produced from defatted soybean meal in a membrane bioreactor. In the first step, soybean meal proteins were digested with trypsin in the bioreactor, operated in batch mode. For the tryptic digestion of soybean meal protein, optimum initial soybean meal concentration of 75 g/L, temperature of 40 °C and pH=9.0 were determined. After en...
