Vitamin D seems to play a role in immunity at the feto-maternal interface by influencing decidual macrophages, dendritic cells, and other leukocytes [1], and maternal vitamin D status in pregnancy may have long-term effects on the fetus [2]. Previously we reported that low concentrations of maternal levels of 25-hydroxyvitamin D (25-OH D) and vitamin D-binding protein (DBP) during pregnancy may be related to higher risk of type 1 diabetes (T1D) in the offspring, in a case–control study nested within nearly 30,000 pregnancies [3].

25-OH D is considered the clinical relevant marker of vitamin D status although calcitriol, or 1,25-dihydroxyvitamin D (1,25-(OH)2 D), is the active hormone binding to the vitamin D receptor. Epidemiological studies suggest that the two vitamin D metabolites may be similarly correlated with some outcomes, but differentially correlated with other outcomes such as different inflammatory markers [4]. Calcitriol is known to increase substantially in pregnancy,...
