Maternal vitamin D, cord blood cytokines, and early childhood allergic diseases: a 2-year cohort study.

Key Points

• To explore the association between maternal vitamin D levels and the risk of allergic diseases in early childhood, with a focus on cord blood cytokines.
• Conducted a 2-year cohort study
• Measured maternal vitamin D levels during pregnancy
• Analyzed cytokines in umbilical cord blood
• Evaluated allergic disease outcomes in early childhood
• Higher maternal vitamin D levels correlated with lower allergic disease risk in offspring
• Cytokines interleukin-4 and interleukin-10 were identified as potential mediators
• Findings suggest that vitamin D impacts immune system development through cytokine regulation
