Research on dialyzers with improved biocompatibility.

A van der Steen

    Clinical Nephrology
    |January 1, 1986
    PubMed
    Summary

    Cuprophan hemodialysis membranes cause leucopenia due to complement activation. New cellulose-based dialyzers aim to improve biocompatibility while maintaining performance for uremic patients.

    Area of Science:

    • Biomaterials Science
    • Nephrology
    • Medical Device Engineering

    Background:

    • Cellulosic membranes like Cuprophan are standard for hemodialysis.
    • Cuprophan induces transient leucopenia and pulmonary dysfunction via complement activation.
    • Synthetic membranes (PAN, PMMA) show less complement activation but have performance limitations.

    Purpose of the Study:

    • To develop improved cellulose-based dialyzers.
    • To combine high performance for routine dialysis with enhanced biocompatibility.
    • To mitigate complement-mediated side effects associated with cellulosic membranes.

    Main Methods:

    • Investigating thinner cellulosic membranes.
    • Exploring modifications of cellulose structure.
    • Evaluating biocompatibility and performance characteristics of novel dialyzers.

    Main Results:

    • Research focused on developing new cellulose-based dialyzers.
    • Two approaches: thinner membranes and modified cellulose.
    • Aims to balance performance and biocompatibility.

    Conclusions:

    • Novel cellulose-based dialyzers are under development.
    • These aim to overcome limitations of current cellulosic and synthetic membranes.
    • Improved biocompatibility and sustained hemodialysis performance are key objectives.
