Reports on the effect of prenatal vitamin D status on fetal immune development and infectious diseases in childhood are limited. The aim of this study was to investigate the role of maternal and cord blood vitamin D level in TLR-related innate immunity and its effect on infectious outcome. Maternal and cord blood 25 (OH)D level were examined from 372 maternal-neonatal pairs and their correlation with TLR-triggered TNF-α, IL-6, and IL-10 response at birth was assessed. Clinical outcomes related to infection at 12 months of age were also evaluated. The result showed that 75% of the pregnant mothers and 75.8% of the neonates were vitamin deficient. There was a high correlation between maternal and cord 25(OH)D levels (r=0.67,p<0.001). Maternal vitamin D level was inversely correlated with IL-10 response to TLR3 (p=0.004) and TLR7-8 stimulation (p=0.006). However, none of the TLR-triggered cytokine productions were associated with cord 25(OH)D concentration. There was no relationship between maternal and cord blood vitamin D status with infectious diseases during infancy. In conclusion, our study had shown that maternal vitamin D, but not cord vitamin D level, was associated with viral TLR-triggered IL-10 response.

The Relationship

Clinical studies and meta-analyzes have shown that reduced levels of 25 (OH) D in the blood contribute to impaired immunity and stimulate excessive inflammation that adversely affects the health of children: the risk of developing bronchial asthma (BA), obstructive bronchitis, and allergic rhinitis increases. The main purpose of this review is to summarize the current literature data on the relationship between vitamin D, VRI and other infectious diseases with a clinical example.

Vitamin D Levels

A link between vitamin D deficiency and susceptibility to infectious diseases was suggested over a hundred years ago. Epidemiological studies show a strong association between seasonal fluctuations in vitamin D levels and the incidence of various infectious diseases, including septic shock, acute respiratory infections, and influenza. Our understanding of vitamin D metabolism and its extra-skeletal functions has improved significantly over the past three decades, and the discovery that the vitamin D receptor and 1a-hydroxylase, an enzyme needed to convert vitamin D to its active form, is present in the cells of the immune system, revolutionized in this area. Recent studies have shown that vitamin D regulates the expression of specific endogenous antimicrobial peptides in immune cells, modulates the immune response and the course of autoimmune processes; these actions indicate the potential role of vitamin D in modulating the immune response to various infectious diseases. This publication reviews the literature on the effects of vitamin D on immunity, its potential in the prevention and treatment of viral diseases, with a particular focus on COVID-19.

A healthy diet is a factor in maintaining and improving health, helping to reduce the risk of developing alimentary-dependent diseases. The article presents the causes of malnutrition, data on the actual deficiency of vitamins and minerals in the population of the Russian Federation. Insufficient content of essential micronutrients in the diet is accompanied by a decrease in the body’s adaptive capabilities, contributing to an increase in the risk of developing non-infectious diseases. The article provides information on the role of chronic low-level inflammation and oxidative stress in the development of noncommunicable diseases. Significant contributors are vitamin D, zinc and selenium, and their deficiencies are widespread. Scientific evidence supports the role of vitamin D, zinc, selenium in the development of non-infectious diseases. The review discusses the role of vitamin D in the development of cardiovascular disorders, discusses the dependence on iron and zinc, which has clinical diagnostic and therapeutic value in anaemia and associated pathological conditions. In addition, the article discusses selenium and zinc deficiencies with the risk of the coronary syndrome, stroke, cardiovascular disease and mortality from them. Despite conflicting data on the effectiveness of oral micronutrient supplementation to prevent and treat chronic noncommunicable diseases, healthcare providers should be informed about the consequences of micronutrient deficiencies and identify micronutrient deficiencies correct them. This is important in treatment and prevention activities for people at risk, especially in endemic disadvantaged regions. The literature search was carried out in the databases PubMed, CyberLeninka, e-library.

Beneficial Role

Abstract. Vitamin D is a secosteroid hormone that plays a pivotal role in several metabolic and reproductive pathways in humans. Increasing evidence supports the role of vitamin D deficiency in metabolic disturbances and infertility in women with polycystic ovary syndrome (PCOS). Indeed, supplementation with vitamin D seems to have a beneficial role on insulin resistance and endometrial receptivity. On the other hand, exceedingly high levels of vitamin D appear to play a detrimental role on oocytes development and embryo quality. In the current review, we summarize the available evidence about the topic, aiming to suggest the best supplementation strategy in women with PCOS or, more generally, in those with metabolic disturbances and infertility. Based on the retrieved data, vitamin D seems to have a beneficial role on IR, insulin sensitivity and endometrial receptivity, but high levels and incorrect timing of administration seem to have a detrimental role on oocytes development and embryo quality. Therefore, we encourage a low dose supplementation (400–800 IU/day) particularly in vitamin D deficient women that present metabolic disturbances like PCOS. As far as the reproductive health, we advise vitamin D supplementation in selected populations, only during specific moments of the ovarian cycle, to support the luteal phase. However, ambiguities about dosage and timing of the supplementation still emerge from the clinical studies published to date and further studies are required.

Potential Treatment

This review summarizes published reports on the utility of melatonin as a treatment for virus-mediated diseases. Of special note are the data related to the role of melatonin in influencing Ebola virus disease. This infection and deadly condition has no effective treatment and the published works documenting the ability of melatonin to attenuate the severity of viral infections generally and Ebola infection specifically are considered. The capacity of melatonin to prevent one of the major complications of an Ebola infection, i.e., the hemorrhagic shock syndrome, which often contributes to the high mortality rate, is noteworthy. Considering the high safety profile of melatonin, the fact that it is easily produced, inexpensive and can be self-administered makes it an attractive potential treatment for Ebola virus pathology.
