Vitamin C and Vascular Permeability in Sepsis

The Mechanism of Action

  • Endothelial Barrier Integrity: Vitamin C plays a crucial role in maintaining and restoring the structural integrity of the vascular endothelium, which is heavily compromised during severe infections and sepsis.
  • Antioxidant Defense: By neutralizing reactive oxygen species (ROS), ascorbic acid reduces oxidative stress-induced damage to the microvasculature, thereby limiting capillary leakage and fluid extravasation.
  • Collagen Synthesis: As an essential cofactor for prolyl and lysyl hydroxylase, vitamin C is necessary for the synthesis and maintenance of basement membrane collagen and extracellular matrix stability in blood vessels.

Clinical Relevance in Sepsis

  • Reduction of Edema: High-dose intravenous vitamin C administration helps attenuate the hyperpermeability state characteristic of the systemic inflammatory response syndrome (SIRS) and sepsis.
  • Vasopressor Sparing: By preserving vascular responsiveness and reducing endothelial permeability, vitamin C therapy has been observed to decrease the requirement for vasopressor support in critically ill patients.
  • Synergy with Other Nutrients: Optimal cellular uptake and clinical efficacy of vitamin C in acute states are significantly enhanced when implemented alongside complementary cofactors such as bioflavonoids, selenium, and vitamin E, addressing underlying biochemical imbalances rather than acting in isolation.
