Omega-3 long chain polyunsaturated fatty acid supplementation in pregnancy and lactation and immune components in breast milk
(English)Manuscript (preprint) (Other academic)
Human milk transfers important immunological information from mother to child. We have previously reported lower prevalence of IgE-mediated disease at 12 months after maternal supplementation with ω-3 long chain polyunsaturated fatty acid (LCPUFA) during pregnancy and lactation. Our aim was to explore the effect of ω-3 LCPUFA on the immune composition of human milk in relation to maternal atopy and allergic disease in the offspring. Pregnant women in families with a history of allergic disease were supplemented daily with 2.7 g ω-3 LCPUFA or 2.8 g soybean oil as placebo from late pregnancy to three months of lactation. Milk samples from colostrum (n=107), at 1 mo (n=102) and at 3 mo (n=95) were analyzed for IL-1ß, IL-2, IL-4, IL-5, IL-6, CXCL-8, IL-10, IL-12p40/p70, IL-13, GM-CSF, TNF, IFN-γ, PGE2, TSLP, TGF-ß2 and SIgA with multiplex assay or ELISA. The levels of several cytokines were higher in non-atopic ω-3 supplemented mothers as compared to placebo supplemented mothers regardless of atopic status. Higher levels of TGFß2 and SIgA in 3 months milk were associated with allergic disease at one year of age both with and without detectable IgE. These results suggest that ω-3 LCPUFA supplementation during pregnancy influences cytokine levels in breast milk especially in non-atopic mothers.
