BACKGROUND: The association between vitamin D receptor (VDR) gene polymorphisms and multiple sclerosis (MS) has been extensively studied, but results were controversial. METHODS: This meta-analysis aimed to confirm whether VDR gene polymorphisms were associated with MS. Meta-analysis on the association between MS and VDR ApaI, BsmI, TaqI and FokI polymorphisms were conducted using allelic contrast, recessive, homozygotes and dominant models. Data were extracted by standardized forms and odds ratios (OR) with 95% confidence intervals (CI) were calculated using the random effects model if the results were heterogeneous...

Vitamin D insufficiency is common, correctable, and influenced by genetic factors, and it has been associated with risk of several diseases. We sought to identify low-frequency genetic variants that strongly increase the risk of vitamin D insufficiency and tested their effect on risk of multiple sclerosis, a disease influenced by low vitamin D concentrations. We used whole-genome sequencing data from 2,619 individuals through the UK10K program and deep-imputation data from 39,655 individuals genotyped genome-wide...

Multiple Sclerosis (MS) is a chronic inflammatory and demyelinating disease of the central nervous system. MS likely results from a complex interplay between predisposing causal gene variants (the strongest influence coming from HLA class II locus) and environmental risk factors such as smoking, infectious mononucleosis and lack of sun exposure/vitamin D. However, little is known about the mechanisms underlying MS development and progression. Moreover, the clinical heterogeneity and variable response to treatment represent additional challenges to a comprehensive understanding and efficient treatment of disease...

Multiple sclerosis (MS) is an inflammatory and neurodegenerative demyelinating disease of the central nervous system (CNS), most likely autoimmune in origin, usually beginning in early adulthood. The aetiology of the disease is not well understood; it is viewed currently as a multifactorial disease which results from complex interactions between genetic predisposition and environmental factors, of which a few are potentially modifiable. Improving our understanding of these factors can lead to new and more effective approaches to patient counselling and, possibly, prevention and management of the disease...

Autoimmune diseases (ADs) are a heterogeneous groups of diseases that occur as a results of loss of tolerance to self antigens. While the etiopathogeneis remain obscure, different environmental factors were suggested to have a role in the development of autoimmunity, including infections, low vitamin D levels, UV radiation, and melatonin. Interestingly, such factors possess seasonal variation patterns that could influence disease development, severity and progression. Vitamin D levels which reach a nadir during late winter and early spring is correlated with increased disease activity, clinical severity as well as relapse rates in several disease entities including multiple sclerosis (MS), non-cutaneous flares of systemic lupus erythematosus (SLE), psoriasis, and rheumatoid arthritis (RA)...

The most recent findings linking exposure to sun and vitamin D insufficiency to multiple sclerosis (MS) are reviewed. Due to insufficient sunshine and changing lifestyles, hypovitaminosis D is widespread in temperate countries. Numerous epidemiological studies have strongly suggested that sunshine and vitamin D insufficiency contributes to MS risk in these countries. Moreover, several large genetic studies in MS patients have recently stated unequivocally that diverse abnormalities involving vitamin D metabolism are related to the risk of the disease...

Dendritic cells (DCs), a bridge of innate and adaptive immune responses, play a key role in the development of multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE), an animal model for MS. Administration of tolerogenic DCs has been used as an immunotherapy in the autoimmune diseases. Deficiency of vitamin D is an environmental risk factor of MS. In this study, we induced tolerogenic DCs by 1,25-dihydroxyvitamin D3 (1,25(OH)2 D3 ) and adoptive transferred the tolerogenic DCs (VD3-DCs) into EAE mice...

BACKGROUND: The cause of Multiple Sclerosis (MS) remains poorly understood, but it is widely believed to be an autoimmune disease occurring in genetically susceptible individuals after exposure to as-yet undefined environmental factors. One of these environmental factors is vitamin D, a well-known immune modulator. The biologically active form of vitamin D, 1,25-dihydroxyvitamin D3, has been shown to exert its immune modulatory properties through its nuclear receptor (VDR) namely by inhibiting the proliferation of Th cells...

PURPOSE OF REVIEW: This article provides an update on the clinical presentation and management of neurologic disease related to key nutrient deficiencies. RECENT FINDINGS: Major advances have been made in understanding the pathway related to vitamin B12 absorption and distribution. It is now known that deficiencies of vitamin B12 and copper have similar neurologic manifestations. Bariatric surgery is a risk factor for both. Alcoholism is just one of the many causes of thiamine deficiency...

Depressive symptoms are common in multiple sclerosis (MS), and both depression and MS have been associated with a poor vitamin D status. As cytokine-mediated inflammatory processes play a role in the pathogenesis of both disorders, we hypothesized that vitamin D3 supplementation reduces depressive symptoms in MS via its immunomodulatory properties. In this randomized pilot study relapsing remitting (RR) MS patients received either vitamin D3 supplementation (n=20; 14.000IU/day) or placebo (n=20) during 48weeks...

We aimed to investigate the immunologic effects of vitamin D replacement in RRMS patients. In a controlled single center study, patients deficient in 25-hydroxyvitamin D (serum level<25ng/ml) received 10,000IU/week cholecalciferol for 3months. Sufficient vitamin D patients (serum level>35ng/ml) were followed for the same period. Assessments were performed at baseline and at 3months. 25-hydroxyvitamin D levels increased significantly from baseline to month-3 in the deficient group after treatment and remained stable in the sufficient group...

Nutrition is considered to be a possible factor in the pathogenesis of the neurological disease multiple sclerosis (MS). Nutrition intervention studies suggest that diet may be considered as a complementary treatment to control the progression of the disease; a systematic review of the literature on the influence of diet on MS was therefore conducted. The literature search was conducted by using Medlars Online International Literature (MEDLINE) via PubMed and Scopus. Forty-seven articles met the inclusion criteria...

Rolf Jorde
Despite thousands of vitamin D studies published, including hundreds of reviews and meta-analyses, it is still uncertain if supplementation with vitamin D will have positive health effects, except for the skeleton. This cannot be answered by doing more observational studies as it is impossible to control for confounding factors and reverse causality. The only way to firmly prove positive vitamin D effects is by doing the properly designed randomized controlled trials (RCTs). However, it has been difficult to show the expected positive effects by vitamin D supplementation in RCTs, which may indicate that the effects, if present must be small...

Alzheimer's disease (AD) may be related to nutritional deficiencies from exocrine pancreatic insufficiency (EPI) with mal-absorption of essential nutrients, vitamins and minerals. EPI occurs in about twenty percent of the elderly population, sometimes without obvious symptoms, a number similar to the incidence of AD. Other Neurological degenerative diseases with potential nutritional components such as Parkinson's disease, frailty of age and Multiple Sclerosis, a disease with increased activity from vitamin D deficiency, may also be related to untreated exocrine pancreatic insufficiency causing impaired absorption of essential dietary elements...
