INTRODUCTION Cytokines are believed to play an important role in acute-on-chronic liver failure (ACLF). Extracorporeal liver support systems may exert beneficial effects in ACLF via removal of cytokines. At present, two systems are commercially available, the Molecular Adsorbent Recirculating System (MARS) and Fractionated Plasma Separation, Adsorption and(More)
BACKGROUND/AIMS Artificial liver support represents a potentially useful option for the treatment of severe liver failure. A sufficient 'dose' might be crucial for such treatments to provide a survival benefit. The aim of this study was to compare in vivo efficiency and resulting delivered treatment dose of two commercially available devices that use(More)
Acute-on-chronic liver failure (ACLF) is accompanied by marked intrahepatic cholestasis leading to accumulation of cytotoxic bile acids. Extracorporeal liver support systems efficiently remove bile acids, but their effect on bile acid composition in ACLF is unknown. The aim of the present study was to compare elimination of individual plasma bile acids by(More)
BACKGROUND The purpose of the study was to examine the relationship between urea and conjugated bilirubin kinetics during extracorporeal liver support (ELS) therapy and to determine the dose of therapy for urea and conjugated bilirubin as markers for water-soluble and protein-bound solutes, respectively. METHODS Kinetics of urea and bilirubin were(More)
Among 92 patients with chronic gastritis we conducted a synchronous diagnosis of the Helicobacter pylori (H. pylori) infection using a culture and a serological test (IFP), in conjunction with breath and urine tests involving (14)C-urea (BTU-C14 and UTU-C14). The infection was confirmed by isolation in 71 persons (77.2%), the presence of specific IgG in the(More)
The influence of pre- and post-irradiation annealing procedures on LiF:Mg,Cu,P (trade name MCP-N) thermoluminescent detector stability was investigated. The detectors were processed in four groups, undergoing complete or incomplete preparation cycles (containing pre- and/or post-irradiation annealing in various combinations). Each cycle was repeated 10(More)
BACKGROUND/AIM To provide a measure of treatment dose for extracorporeal liver support (ELS). METHODS The kinetics of conjugated bilirubin were described by a two-compartment model (Vc, Vp) with central elimination (K) and constant generation rate (G). The transfer of solute between compartments was modeled by intercompartmental clearance (Kpc). The(More)
Measurements of the dose rate changes were carried out in order to assess seasonal and spatial radioactivity variations in the largest limestone cave of the Polish Jura Wierzchowska Górna. Thermoluminescence detectors, which were annealed, calibrated and protected against humidity were used. Measurements were repeated four times in 13 locations to observe(More)
