Clinical results of daily hemofiltration

Various types of daily hemodialysis (HD) have been developed. However, a water treatment system is essential for HD, which markedly prevents daily home HD. Hemofiltration (HF) can be simply performed only with substitution fluid without a water treatment system. This advantage is applied to daily HF. To perform this procedure at home, a simple system is needed. A system in which a dialyzer was combined with a circuit as one cartridge with bag-type substitution fluid was developed by NxStage Inc. This system facilitates not only HF via a supply of 15 l of bag-type substitution fluid, but also automatic washing/priming of the circuit and returning which can be achieved by applying the current CAPD management system. This daily HF may contribute to routine home HD in the future.
