Vitamin D is a potent immunomodulator and may play a role in the development of the fetal innate immune functions. The aim of our study was to evaluate inflammatory markers in cord blood of healthy newborns in relation to vitamin D status at birth.

We studied the concentrations of inflammatory markers, matrix metalloproteinase 8 (MMP-8) and high sensitivity CRP (hs-CRP), and 25-hydroxyvitamin D (25(OH)D) in cord blood of 939 healthy term infants born to mothers of Caucasian origin. We evaluated perinatal factors that affect the concentrations of MMP-8 and hs-CRP, and further explored associations between cord blood 25(OH)D and these inflammatory biomarkers.

Majority (99%) of the cohort was vitamin D sufficient (>50 nmol/L or 20 ng/mL). We observed a positive correlation between cord blood 25(OH)D and MMP-8 concentrations, and between 25(OH)D and hs-CRP concentrations. After adjustment for potential confounders (parity, antenatal antibiotic treatment, gestational age, mode of delivery and maternal prepregnancy body mass index), the association of 25(OH)D with MMP-8 and hs-CRP remained significant.

Cord blood 25(OH)D correlates with inflammatory markers MMP-8 and hs-CRP. The findings may reflect the diverse immunomodulatory functions of vitamin D in the innate immune response of the newborn.
