Maternal and cord blood ascorbic acid levels at parturition.

Area of Science:

• Biochemistry
• Neonatal Health
• Maternal-Fetal Medicine

Background:

• Ascorbic acid, also known as vitamin C, is crucial for numerous physiological functions.
• Leukocyte ascorbic acid (LAA) levels reflect vitamin C status within the body.
• Understanding maternal and neonatal vitamin C levels is important for infant health.

Purpose of the Study:

• To measure and compare leucocyte ascorbic acid (LAA) levels in healthy mothers and their newborn infants immediately after delivery.
• To investigate the relationship and potential gradient of LAA between maternal and fetal circulation.

Main Methods:

• A cohort of 50 healthy women and their newborn infants were recruited for the study.
• Leukocyte ascorbic acid (LAA) levels were measured in both mothers and newborns post-delivery.
• Statistical analysis was performed to determine mean LAA levels and compare maternal and infant values.

Main Results:

• The mean corrected LAA level for mothers was 10.9 microgram/10(8)WBC.
• The mean corrected LAA level for newborns was 17.1 microgram/10(8)WBC.
• A significant gradient was observed, with higher LAA levels in newborns compared to their mothers.

Conclusions:

• Newborn infants exhibit higher LAA levels than their mothers shortly after birth.
• This finding suggests a potential active transport mechanism or differential distribution of ascorbic acid between mother and fetus.
• Further research is warranted to elucidate the implications of this maternal-fetal LAA gradient for neonatal health and development.
