    This study introduces thermofiltration, a novel procedure for selectively removing harmful LDL cholesterol while preserving beneficial HDL cholesterol and essential proteins in hypercholesterolemia patients. The method shows promise for effective lipid management.

    Area of Science:

    • Cardiovascular Science
    • Biomedical Engineering
    • Nephrology

    Background:

    • Secondary hypercholesterolemia management requires selective removal of atherogenic lipoproteins.
    • Existing treatments like plasma exchange can deplete essential plasma components.

    Observation:

    • The first clinical thermofiltration procedure was successfully performed on a patient with secondary hypercholesterolemia.
    • An EVAL 4A filter was utilized at 37°C for on-line thermofiltration.

    Findings:

    • Thermosfiltration demonstrated selective removal of LDL + VLDL cholesterol (sieving coefficient 0.02).
    • High retention of HDL cholesterol (0.75) and albumin (0.78) was observed, comparable to in vitro results.
    • The procedure is simple, requires no replacement solution, and allows high return of essential solutes.

    Implications:

    • Thermosfiltration offers a promising alternative for managing hypercholesterolemia with improved preservation of beneficial lipoproteins and proteins.
    • This technique could enhance patient outcomes by minimizing the loss of essential plasma components compared to plasma exchange.
