The study revealed an association between low 25-hydroxyvitamin D levels and an increased risk of late-onset sepsis in preterm infants. Additionally, a positive correlation was found between maternal and neonatal 25-OHD levels.
Introduction: We investigated the association between low 25-hydroxyvitamin D (25-OHD) levels and late-onset sepsis (LOS) in preterm infants (<37 weeks). Methods: Infants with culture-proven LOS were the study group, infants without LOS were the controls. 25-OHD levels were compared between these groups. Low vitamin D was defined as 25-OHD <= 15 ng/ml. Maternal 25-OHD levels were compared to their infant's level. Results: 108 infants were included. The study group was significantly younger (p = 0.02) with significantly lower 25-OHD levels (p < 0.001). Multivariable logistic regression analyses revealed that infants with low 25-OHD levels were 7.159 (95%CI: 1.402-36.553, p = 0.018) times more likely to develop LOS. A positive correlation was detected between maternal and neonatal 25-OHD levels for both study and control groups (r = 0.425, p = 0.009; r = 0.739, p < 0.001, respectively). Conclusions: Low 25-OHD levels are associated with an increased risk of developing LOS development in preterm infants
