    Acetate dialysis paradoxically increases l-ascorbatemia in the first hour, unlike bicarbonate dialysis or biofiltration. This rise may be linked to relative acidosis during early acetate dialysis sessions.

    Area of Science:

    • Nephrology
    • Biochemistry
    • Dialysis Therapy

    Background:

    • Ascorbate (vitamin C) levels can fluctuate during dialysis.
    • Acetate and bicarbonate are common dialysis buffer solutions with different physiological effects.

    Purpose of the Study:

    • To investigate the intradialytic behavior of l-ascorbatemia during acetate and bicarbonate dialysis.
    • To compare l-ascorbatemia changes during acetate dialysis, bicarbonate dialysis, and biofiltration.

    Main Methods:

    • Observational study monitoring l-ascorbatemia levels during different dialysis modalities.
    • Comparison of intradialytic l-ascorbatemia curves between acetate dialysis, bicarbonate dialysis, and biofiltration.

    Main Results:

    • A paradoxical increase in l-ascorbatemia was observed during the first hour of acetate dialysis.

  • Intradialytic l-ascorbatemia during biofiltration mirrored bicarbonate dialysis patterns, despite using an acetate bath.
  • The observed rise in l-ascorbatemia during acetate dialysis may be attributed to relative acidosis.

    • Conclusions:

    • Acetate dialysis can lead to a transient increase in blood ascorbate levels.
    • The buffering system used in dialysis significantly impacts intradialytic ascorbate kinetics.
    • Relative acidosis might explain the paradoxical increase in l-ascorbatemia during early acetate dialysis.
