“…The incidence of atopic manifestations is typically higher among boys [7], and our results are in accordance with this gender difference. As in other studies [30], our study showed an inverse relationship between 25(OH)D level and age in healthy children and adolescents.…”

This study assessed vitamin D status in asymptomatic children and adolescents in Greece, with and without atopy, and possible changes during the coronavirus disease 2019 (COVID-19) pandemic. Serum levels of 25-hydroxy-vitamin D (25(OH)D) and total immunoglobulin E (IgE), and eosinophil count were measured in 340 asymptomatic children and adolescents (155 males, 185 females), mean age 8.6 ± 4.6 years, recruited over a period of 24 months (February 2019–January 2021). Atopy, defined by high level of IgE for age, was associated with vitamin D deficient status (p = 0.041). Subjects with and without atopy showed similar rates of insufficient and normal levels of 25(OH)D. The median level of 25(OH)D was significantly higher in subjects recruited during the pandemic, when home confinement rules were observed, than before the pandemic, and significantly more children had normal levels of 25(OH)D (p < 0.001), but no differences were noticed for IgE levels or eosinophil count. These results support a link between vitamin D and allergic and infectious inflammations, and specifically the association of vitamin D deficiency with asymptomatic atopy, defined as increased IgE level for age.

“…Other sources of vitamin D3 (cholecalciferol) are animal foods and vitamin D3 supplements, while vitamin D2 (ergocalciferol) is derived from the intake of vegetable foods and vitamin D2 supplementation [ 50 ]. As exposure to the sun varies according to the season, time of day, latitude, altitude, skin pigmentation and other conditions, food sources are required to cover the required 15 μg daily intake set by the European Food Safety Authority (EFSA) [ 51 , 52 ]. Good sources of dietary vitamin D2 are oily fish and fish liver oils, mushrooms, reindeer lichen ( Cladonia rangiferina ), beef liver, eggs, dark chocolate and cheese.…”

Vitamin D and Omega-3 (Fatty Acid) Supplementation in Pregnancy for the Primary Prevention of Food Allergy in Children-Literature Review

During the last decades the prevalence of food allergy (FA), an adverse immune response to a specific food antigen, has risen, with negative effects on the quality of life (QoL) of many children and their families. The pathogenesis of FA is complex, involving both genetic and environmental factors. SPINK5, STAT6, HLA and FOXP3 are some of the genes that are reported to be implicated in FA development. Regarding environmental factors, particular interest has been focused on modification of the dietary habits of pregnant women for the primary prevention of FA. Specifically, Vitamin D and omega-3 (Ω-3) fatty acid supplementation during pregnancy may influence the development of FA in the offspring. Vitamin D is a hormone with various actions, including mediation of the immune system, reducing the production of inflammatory cytokines and promoting tolerance. Vitamin D deficiency in pregnancy suppresses T-regulatory cells in the fetus, and Vitamin D supplementation might protect against FA development. Dietary Ω-3 fatty acids are found mainly in fish and vegetable oils. They are beneficial for human health, playing a role in the immune system as anti-inflammatory agents, and providing cell membrane stabilization with inhibition of antigen presentation. It is documented that maternal supplementation with Ω-3 during pregnancy may protect from allergic sensitization in the children. The aim of this literature review was to explore the potential preventive role of maternal supplementation during pregnancy with Vitamin D and Ω-3 in the development of FA in the offspring. With the prevalence of FA rising, all the possible protective mechanisms and measures for FA prevention need to be explored, starting with those that can be modified.

“…9,17 These data also showed that VD status in early childhood was not affected by gender and was similar to that of Greek counterparts. 37 Vitamin D status in late-stage children and adolescents was influenced by gender, which differed from the findings of European and Greek counterparts. 9,37 These differences in VD status are thought to be related to supplemental VD intake and lifestyle (outdoor activities).…”
