Are antioxidant enzyme activities decreased in preterm infants and in neonates born via caesarean section? Context: To investigate the antioxidant defense potential of human neonates according to gestational age and mode of delivery. Four study groups were established, full-term normal spontaneous vaginal delivery (FT-NSVD, n=24), full-term caesarean section (FT-CS, n=19), preterm normal spontaneous vaginal delivery (PT-NSVD, n=15) preterm caesarean section (PT-CS, n=21). The activity of catalase (CAT), glutathion peroxidase (GPX), Cu/Zn superoxide dismutase (Cu/Zn-SOD) were determined from cord blood. Statistical analysis was made by ANOVA. CAT activity was significantly higher in full-term than in preterm newborns. In both the categories, neonates born via caesarean section had significantly lower CAT activities. GPX activity was significantly higher in the FT-NSVD group than in any other group. Cu/Zn-SOD activity was significantly higher in full-term neonates than in preterms and no difference was found related to the mode of delivery.

Prematurity and caesarean section may cause a deficiency of antioxidant defense in human newborn. Final Decision: yes
