The influence of vitamin D on the women’s health is undeniable. Here we review the modern classification of vitamin D forms and receptors, the current understanding of genomic and non-genomic regulation pathways of vitamin D synthesis. It was found that a vitamin D deficiency related to the development of many diseases, negative impact on reproductive function and pregnancy outcomes. Nowadays, vitamin D is concerned as a prohormone that has multiple effects. Special attention is given to the role of vitamin D in the pathogenesis of genital endometriosis. It is known that vitamin D has anti-inflammatory, antiproliferative and immunomodulating effects, which allow it to be considered as a forward-looking target therapy in endometriosis.

The Relationship

Abstract The role of vitamin D beyond that it plays in bone metabolism and calcium homeostasis has been lately quite emphasized. In this respect, vitamin D deficiency has been associated with higher risk of cardiovascular disease, metabolic syndrome, and reproductive disorders. Growing evidence has suggested that vitamin D deficiency is implicated in the pathogenesis of insulin resistance and the development of metabolic disorders in the polycystic ovary syndrome. The goal of the review is to present contemporary concepts of the relationship between hormones affecting the metabolic body status, serum vitamin D levels and the reproductive function.

Meta Analyses

Vitamin D deficiency is common and there exists a huge gap between recommended dietary vitamin D intakes and the poor vitamin D supply in the general population. While vitamin D is important for musculoskeletal health, there are accumulating data suggesting that vitamin D may also be important for fertility, pregnancy outcomes and lactation. Significant changes in vitamin D metabolism during pregnancy such as increased production of the “active vitamin D hormone” calcitriol support the important role of vitamin D in this setting. Observational studies show that vitamin D deficiency is a risk marker for reduced fertility and various adverse pregnancy outcomes and is associated with a low vitamin D content of breast milk. Meta-analyses of randomized controlled trials (RCTs) document that physiological vitamin D supplementation during pregnancy is safe and improves vitamin D and calcium status, thereby protecting skeletal health. Although certain RCTs and/or meta-analyses reported some other beneficial effects, it is still not clear whether vitamin D supplementation improves fertility or decreases the risk of adverse pregnancy outcomes such as low birth weight, pre-eclampsia and neonatal mortality, or reduces wheeze/asthma in the infants. Nevertheless, vitamin D supplementation in pregnant women is frequently required to achieve a sufficient vitamin D status as recommended by nutritional vitamin D guidelines. In this review, we provide an overview of systematic reviews, meta-analyses and large trials reporting clinical data on the role of vitamin D for fertility, pregnancy and lactation.

Relevance. Due to the high prevalence of uterine fibroids in women of reproductive age and the negative impact on reproductive health, one of the priority tasks of specialists is to search not only for new therapeutic methods, but also for ways to prevent this disease. Aim. To determine the role of vitamin D deficiency in the risk of uterine fibroids recurrence after surgical treatment in women of reproductive age. Materials and methods. A comparative analysis of the recurrence rate of uterine fibroids in patients of reproductive age after surgical treatment. The study involved 49 women of reproductive age 20-39 years (average age 31.5±4.3 years) with unrealized reproductive plans. All underwent surgical treatment in the scope of laparoscopic conservative myomectomy for uterine fibroids with different symptoms. All patients were given vitamin D levels. Results. In 93.5% of cases, the risk of recurrence of uterine fibroids increases at vitamin D levels below 34.5 ng/ml, when reaching 38.6 ng/ml and above, the risk of reformation of nodes is minimal. Conclusions. When the vitamin D level exceeds 38.6 ng/ml, it is possible to minimize the risk of recurrence of uterine fibroids in women of reproductive age, thereby avoiding repeated surgical interventions and associated complications.

Background. Vitamin D is an essential component that regulates calcium homeostasis and many other cellular functions. Hypovitaminosis D is associated with a risk of osteopenia, obesity, type 1 and type 2 diabetes, malignant neoplasms and immune disorders. Inadequate vitamin D intake during pregnancy increases a risk of pre-eclampsia, preterm birth, low birth weight as well as it has a negative impact on both children’s and adolescents’ health. It is important for the clinician to be known administrating of vitamin D prophylactic and therapeutic regimens according to serum 25(OH)D levels. Aim. To determine causes and effects of vitamin D deficiency and to elaborate ways of their correction. Materials and methods. To write this review a search for domestic and foreign publications in Russian and international search systems (PubMed, eLibrary, etc.) for the last 2-15 years was conducted. The review includes articles from peer-reviewed literature. Results. The article shows that vitamin D has a significant impact on both the cardiovascular, endocrine, digestive, respiratory and other systems functioning and perinatal outcomes that necessitates vitamin D deficiency correction. It provides schemes for effective therapeutic and prophylactic drug doses calculating depending on vitamin D3 blood serum concentration. Conclusion. Preference should be given to cholecalciferol (vitamin D3) due to its better absorption properties and more efficient conversion to active vitamin metabolites (class IIC).

The Impact

Background: Vitamin D exerts multiple pleiotropic effects beyond its role in calcium-phosphate metabolism. Growing evidence suggests an association between hypovitaminosis D and sleep disorders, thus increasing the interest in the role of this vitamin in the regulatory mechanisms of the sleep-wake cycle. Objective: The study aimed to explore and summarize the current knowledge about the role of vitamin D in sleep regulation and the impact of vitamin D deficiency on sleep disorders. Methods: The main regulatory mechanisms of vitamin D on sleep are explained in this study. The literature was scanned to identify clinical trials and correlation studies showing an association between vitamin D deficiency and sleep disorders. Results: Vitamin D receptors and the enzymes that control their activation and degradation are expressed in several areas of the brain involved in sleep regulation. Vitamin D is also involved in the pathways of production of Melatonin, the hormone involved in the regulation of human circadian rhythms and sleep. Furthermore, vitamin D can affect sleep indirectly through non-specific pain disorders, correlated with alterations in sleep quality, such as restless legs syndrome and obstructive sleep apnea syndrome. Conclusions: : Vitamin D has both a direct and an indirect role in the regulation of sleep. Although vitamin D deficiency has been associated to sleep disorders, there is still scant evidence to concretely support the role of vitamin D supplementation in the prevention or treatment of sleep disturbances; indeed, more intervention studies are needed to better clarify these aspects.

The Common Krait (Bungarus caeruleus) shares a distribution range with many other ‘phenotypically-similar’ kraits across the Indian subcontinent. Despite several reports of fatal envenomings by other Bungarus species, commercial Indian antivenoms are only manufactured against B. caeruleus. It is, therefore, imperative to understand the distribution of genetically distinct lineages of kraits, the compositional differences in their venoms, and the consequent impact of venom variation on the (pre)clinical effectiveness of antivenom therapy. To address this knowledge gap, we conducted phylogenetic and comparative venomics investigations of kraits in Southern and Western India. Phylogenetic reconstructions using mitochondrial markers revealed a new species of krait, Romulus’ krait (Bungarus romulusi sp. nov.), in Southern India. Additionally, we found that kraits with 17 mid-body dorsal scale rows in Western India do not represent a subspecies of the Sind Krait (B. sindanus walli) as previously believed, but are genetically very similar to B. sindanus in Pakistan. Furthermore, venom proteomics and comparative transcriptomics revealed completely contrasting venom profiles. While the venom gland transcriptomes of all three species were highly similar, venom proteomes and toxicity profiles differed significantly, suggesting the prominent role of post-genomic regulatory mechanisms in shaping the venoms of these cryptic kraits. In vitro venom recognition and in vivo neutralisation experiments revealed a strong negative impact of venom variability on the preclinical performance of commercial antivenoms. While the venom of B. caeruleus was neutralised as per the manufacturer’s claim, performance against the venoms of B. sindanus and B. romulusi was poor, highlighting the need for regionally-effective antivenoms in India.
