Immunohistochemical Expression of Vitamin D Receptor in Uterine Fibroids
2022
One of the many factors involved in the development of uterine fibroids is vitamin D deficiency. One aspect of this deficiency is decreased serum concentration of calcidiol-25(OH)D, a metabolite of D3 vitamin. The active form of vitamin D3, which arises after numerous enzymatic reactions, is calcitriol-1,25(OH)2D3; this compound is transported to various body tissues. Vitamin D possesses extra-genomic effects due to its influence on various signaling pathways, i.e., through activating tyrosine kinases and by genomic effects via binding to a specific nuclear receptor, vitamin D receptor (VDR). The vitamin D/VDR complex regulates the expression of genes and is involved in the pathogenesis of …
THE ROLE OF HIGH-DOSE VITAMIN D IN RISK REDUCTION OF OSTEONECROSIS OF THE JAW IN CANCER PATIENTS RECEIVING ZOLEDRONIC ACID
Osteonecrosis of the jaw (ONJ) is a serious complication of oncological patients after or during drug therapy, whose manifestations range from asymptomatic to aspects requiring extensive operative treatment and adversely affecting patient’s qualify of life. Taking in account that the lack of supplementation vitamin D causes hypovitaminosis, increasing bone renewal, losing bone mass, and in severe cases determing osteomalacia (one of the risk factors for ONJ) and that the probability of developing ONJ increases significantly during the first 3 years of treatment, the main objective of the present study is to assess whether the implementation of high-dose vitamin D in oncologic patients treat…
Vitamin D in cancer chemoprevention
2015
Context: There is increasing evidence that Vitamin D (Vit D) and its metabolites, besides their well-known calcium-related functions, may also exert antiproliferative, pro-differentiating, and immune modulatory effects on tumor cells in vitro and may also delay tumor growth in vivo. Objective: The aim of this review is to provide fresh insight into the most recent advances on the role of Vit D and its analogues as chemopreventive drugs in cancer therapy. Methods: A systematic review of experimental and clinical studies on Vit D and cancer was undertaken by using the major electronic health database including ISI Web of Science, Medline, PubMed, Scopus and Google Scholar. Results and conclus…

Vitamin D in the Prevention and Treatment of Diabetic Neuropathy.
2022
Neuropathy is one of the most important complications of diabetes. According to recent advances, vitamin D deficiency might play a role in the development and progression of diabetic neuropathy. Moreover, therapeutic vitamin D supplementation has the potential to improve this condition. The aim of the present review was to summarize new data available in this area.The PubMed database was searched for articles written in English and published through September 2021, using combinations of the following key words: vitamin D, diabetes, diabetes mellitus, diabetic neuropathy, polyneuropathy, peripheral neuropathy, cardiac autonomic neuropathy, supplementation, and therapy.A number of studies hav…
A new road to improve vitamin D and balance through Taopatch® and proprioceptive protocol in Multiple Sclerosis patients
2022
: In multiple sclerosis patients (MS), symptoms such as fatigue, lack of physical energy, spasticity, motor coordination disorders, tremors, dizziness and postural instability are most common. Cattaneo et al. (2007) studied the effects of stability training on MS patients, describing its efficacy in reducing all risks, by improving stability, and strength. The present study aimed to confirm our 2021 results on MS patients, combining the Taopatch® device with a proprioceptive rehabilitation protocol (PRP) targeting strength, balance, and biochemical parameters including vitamin D levels. Twenty MS patients, 8 males and 12 females, volunteered in the study. A KERN MAP Version 1.2 08/2012, Han…
Effect of Calcifediol on Physical Performance and Muscle Strength Parameters: A Systematic Review and Meta-Analysis
2022
There is general agreement that optimal vitamin D status is necessary for bones, muscles, and general health, particularly in older adults, who are at higher risk of negative consequences of vitamin D deficiency, including sarcopenia; vitamin D supplementation is proposed as a potential intervention to mitigate sarcopenia. Several RCTs have reported that calcifediol (25(OH)D) was more potent than cholecalciferol in increasing plasma 25(OH)D. The present systematic review and meta-analysis aimed to summarize the effects of calcifediol on physical performance and muscle strength. We searched databases from inception to 1 January 2022 for studies investigating calcifediol on physical performan…
Vitamin D Deficiency in HIV Infection: Not Only a Bone Disorder
2015
Hypovitaminosis D is a worldwide disorder, with a high prevalence in the general population of both Western and developing countries. In HIV patients, several studies have linked vitamin D status with bone disease, neurocognitive impairment, depression, cardiovascular disease, high blood pressure, metabolic syndrome, type 2 diabetes mellitus, infections, autoimmune diseases like type 1 diabetes mellitus, and cancer. In this review, we focus on the most recent epidemiological and experimental data dealing with the relationship between vitamin D deficiency and HIV infection. We analysed the extent of the problem, pathogenic mechanisms, clinical implications, and potential benefits of vitamin …
The complex interplay between vitamin D deficiency and diabetes
2015
It has been recently highlighted the link between vitamin D and metabolic and immunological pro- cesses, which established its role as an essential component of human health preservation. Vitamin D has been defined as natural immune modulators, and through the activation of its receptors (VDRs), it regulates calcium metabolism, cellular growth, proliferation and apoptosis, and other immunological functions. In this setting, vita- min D has also been reported to influence glucose regulation via effects on insulin secretion and action. Vitamin D deficiency is strongly associated with obesity mostly due to the storage of vitamin D in adipose tissue because of its lipophilic properties. The dec…
INTESTINAL DYSBIOSIS AND HORMONAL NEUROENDOCRINE SECRETION IN THE FIBROMYALGIC PATIENT: RELATIONSHIP AND CORRELATIONS
2018
Fibromyalgia is a rheumatic syndrome and its pathogenesis is controversial. The recent literature has placed considerable attention on the link between alteration of the intestinal microbiota and fibromyalgia, emphasizing the close connection between the neuroenteric system and the CNS. This study aims to evaluate the probable relationship between intestinal dysbiosis and altered secretion of hormones and vitamins such as cortisol, serotonin, Vitamin D and thyroid hormones in a patient with fibromyalgia.
