Improvement of neutrophil migration by systemic vitamin C in neonates
1Department of Neonatology, Interfaith Medical Center, Brooklyn, New York.
Insights
Oral vitamin C significantly improved neutrophil migration in neonates. This finding suggests vitamin C could be a valuable addition to neonatal sepsis treatment strategies.
Area of Science:
- Neonatal immunology
- Nutritional science
- Inflammatory response
Background:
- Neutrophil dysfunction can impair host defense in neonates.
- Neonatal sepsis presents a significant challenge due to immature immune systems.
- Vitamin C (ascorbic acid) is a crucial antioxidant with immunomodulatory roles.
Purpose of the Study:
- To investigate the impact of oral vitamin C on neutrophil migration in neonates.
- To assess whether vitamin C supplementation enhances neutrophil chemotaxis and random migration.
- To evaluate the potential of vitamin C as an adjunctive therapy for neonatal sepsis.
Main Methods:
- Study involved 20 neonates (10 normal, 10 with suspected sepsis).
- Neutrophil chemotactic and random migration assessed before and 24 hours after vitamin C administration.
- Vitamin C dosage: 400 mg daily, divided into four doses.
Main Results:
- Chemotactic migration of neutrophils increased by 65% post-vitamin C.
- Random migration of neutrophils improved by 57% after vitamin C supplementation.
- Improvements in both migration types were statistically significant (P < .01).
Conclusions:
- Oral vitamin C administration demonstrably enhances neutrophil migration in neonates.
- The observed improvements suggest vitamin C's potential as an adjunctive therapy for neonatal sepsis.
- Further research may support the routine use of vitamin C in neonatal care for sepsis management.
Abstract:
The effect of oral vitamin C on chemotactic and random migration of neutrophils in 20 neonates (10 normal and 10 with suspected sepsis) was evaluated. Chemotaxis and random migration were studied between 24 and 48 hours of life, before and 24 hours after the administration of 400 mg (divided in four doses) of vitamin C. Chemotactic migration improved by 65% and random migration by 57% following vitamin C administration. The significant improvement in chemotaxis (P less than .01) and random migration may justify the inclusion of vitamin C as an adjunct to the therapy of neonatal sepsis.
