Abstract

Purpose: We explored the effect of winter cholecalciferol (vitamin D₃) supplementation on innate immune markers in healthy Danish children (55°N). Methods: In the double-blind, placebo-controlled trial, ODIN Junior, 119 healthy, white, 4–8 year-olds were randomized to 0 (placebo), 10 or 20 µg/day of vitamin D₃ for 20 weeks (October–March). Cheek mucosal swabs, blood samples, and questionnaires on acute respiratory infections the previous month were collected at baseline and endpoint. Innate immune markers were measured as secondary outcomes including in vivo oral mucosal gene expression of calprotectin (S100A9), lipocalin-2 (LCN2), beta-defensin-4 (DEFB4), interleukin-8 (IL-8), viperin (RSAD2), and the cathelicidin-antimicrobial-peptide (CAMP); ex vivo whole-blood lipopolysaccharide (LPS)-induced cathelicidin, IL-8, and IL-6; and plasma cathelicidin, together with serum 25-hydroxyvitamin D [25(OH)D]. Results: Serum 25(OH)D was 56.7 ± 12.3 nmol/L at baseline and 31.1 ± 7.5, 61.8 ± 10.6, and 75.8 ± 11.5 nmol/L at endpoint after placebo, 10 and 20 µg/day of vitamin D₃ (P < 0.0001), respectively. A decreased oral mucosal S100A9 expression with placebo [− 18 (95% CI − 1; − 32)%] was marginally avoided with 20 µg/day [6 (− 13; 28)%] (P = 0.06). Likewise, a decreased LPS-induced IL-8 with placebo [− 438 (95% CI − 693; − 184) ng/L] was marginally avoided with 20 µg/day [− 109 (− 374; 157) ng/L] (P = 0.07). All other immune markers and respiratory infection episodes were unaffected by vitamin D₃ supplementation (all P > 0.11). Conclusions: Winter vitamin D₃ supplementation of 10 µg/day did not affect innate immune markers, whereas 20 µg/day tended to maintain the capacity to produce a few markers in healthy children.
