heal.abstractRenal replacement therapy makes extensive use of semi-permeable membranes, ideal requirements for such membranes are good solute transport characteristics and a low reactivity with blood. Membranes manufactured from synthetic polymers fulfil these requirements. Such membranes have asymmetric and anisotropic structures characterized by a dense layer with which the blood is in contact supported by a thicker solid structure with containing interlinked voids, providing support. The nature of the structures are critically dependent upon the polymer blend and the control of parameters during manufacture such as the temperature or additive concentrations. In this prospective study, we have evaluated the clinical performance of a new membrane manufactured from a blend of polyamide, polyarylethersulfone and polyvinylpyrrolidone (Polyflux, Gambro GmbH, Hechingen, Germany), and compared it with that of polysulfone blended with polyvinylpyrrolidone (Fresenius Polysulfone, Fresenius Medical Care, Bad Homburg, Germany), a material widely acknowledged as providing an optimal biocompatibility in terms of solute removal and complement activation. The clearance of small molecules (urea, creatinine, phosphate) for both membranes was comparable. Both membranes removed beta2 microglobulin during treatment (50.2% reduction with Polyflux and 54.5% reduction with polysulfone. This removal due to the non-selectivity of the membranes was associated with protein loss during therapy which was similar for both the membranes (7.7 g). The biocompatibility profiles of the membranes indicated slight neutropenia and platelet adhesion and minimal C3a, C5a and SC5b-9 generation which were independent of the membrane material. These findings indicate that despite the differences in microstructure of the membranes, their functional performance in the clinical setting is comparable.en
