1. Severe anaphylactoid reactions have been reported in some patients treated with angiotensin converting enzyme (ACE) inhibitors during hemodialysis with a polyacrylonitrile (PAN) membrane. Generation of bradykinin via contact activation at the negatively charged membrane surface and reduced bradykinin breakdown due to ACE inhibition have been suggested as possible causes. This hypothesis was ...

in this research, modification on the ultrafiltration (uf) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (fo) water treatment. two monomers, m-phenylenediamine (mpd) and trimesoyl chloride (tmc) with different concentrations of mpd (2.0% w/v and 1.0% w/v) were reacted with tmc (0.15% w/v) for interfacial polymerization (...

BACKGROUND Intravenous iron is typically administered during the hemodialysis (HD) procedure. HD patients may be prescribed high-flux (HF) or high-efficiency (HE) dialysis membranes. The extent of iron sucrose and iron dextran removal by HD using HF or HE membranes and by ultrafiltration rate (UFR) is unknown. METHODS Two in vitro HD systems were designed and constructed to determine the dial...

BACKGROUND The AN69 ST haemodialysis membrane, a new membrane resulting from coating polyethyleneimine upon the polyacrylonitrile surface, binds heparin. In patients at risk of bleeding, a pilot study has demonstrated the efficient anticoagulant effect of this heparin-coated membrane. Study design. In chronic haemodialyzed patients, we evaluated whether this anticoagulant effect can be validate...
