Vitamin C in surgical sepsis

Area of Science:

• Critical Care Medicine
• Nutritional Biochemistry
• Pharmacology

Background:

• Sepsis and septic shock are life-threatening conditions characterized by dysregulated host response to infection.
• Current management focuses on hemodynamic support and infection control.
• Vitamin C, an antioxidant, is investigated for its potential to modulate inflammatory responses and improve resuscitation outcomes.

Purpose of the Study:

• To review the supplemental use of vitamin C as an adjunct therapy in sepsis and septic shock.
• To evaluate the potential benefits of vitamin C in modulating inflammation and improving resuscitation.
• To assess the current evidence for vitamin C efficacy and safety in human sepsis.

Main Methods:

• Review of existing literature, including animal studies and human clinical trials (prospective and retrospective).
• Analysis of meta-analyses examining vitamin C's impact on sepsis outcomes.
• Assessment of proposed mechanisms of action for vitamin C in sepsis.

Main Results:

• Animal and burn study data suggest potential benefits in fluid resuscitation and reduced vasopressor needs.
• Recent meta-analyses of human sepsis data do not demonstrate a significant survival benefit.
• Concerns regarding potential nephrotoxicity associated with vitamin C administration persist.

Conclusions:

• While promising in preclinical models, robust evidence supporting vitamin C's efficacy in improving sepsis survival in humans is lacking.
• Further high-quality, randomized controlled trials are necessary to definitively establish the role of vitamin C in sepsis management.
• The current evidence is inconclusive regarding the addition of vitamin C to standard sepsis treatment bundles.
