BACKGROUND: Multiple sclerosis (MS) is a chronic, demyelinating disease of the central nervous system (CNS). Genetic and environmental factors are important in disease development. Many studies have investigated the relationship between MS and VDR polymorphisms. VDR gene polymorphism has not been previously studied in Turkish MS patients. We aimed to investigate the relationship between MS and VDR genotypes Taq I, Apa I and Fok I polymorphisms in a Turkish population. METHODS: 167 MS patients and 146 healthy control subjects were included in the present study...

BACKGROUND: Increased adiposity is a risk factor for multiple sclerosis (MS) and is associated with increased disability scores. Adipokines may mediate the effects of adiposity on MS disease course. OBJECTIVE: The objective of this study is to examine the association between the adipokines (leptin and fatty acid binding protein-4, FABP4) and clinical course in individuals with MS. METHODS: Subjects (18-65 years) with relapsing-remitting MS or clinically isolated syndrome and <10 year disease duration were selected from a longitudinal clinical study...

Multiple sclerosis (MS) is a genetically mediated autoimmune disease of the central nervous system. Allelic variants lead to lower thresholds of T-cell activation resulting in activation of autoreactive T cells. Environmental factors, including, among others, diet, vitamin D, and smoking, in combination with genetic predispositions, play a substantial role in disease development and activation of autoreactive T cells. FoxP3+ regulatory T cells (Tregs) have emerged as central in the control of autoreactive T cells...

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system (CNS) and a major contributor to disability of young adults in western countries. MS prevalence is highest in areas with low vitamin D. Vitamin D is a fat-soluble compound with numerous physiologic responses, including immune regulation. An increasing volume of work suggests that lower levels of serum vitamin D are associated with an increased risk of MS and a more severe disease course. With the suggestion of a role in MS disease activity, increasing attention is being paid to the potential of using vitamin D as an add-on therapy to established MS disease-modifying therapies...

The etiology of multiple sclerosis (MS) involves a complex interplay of genetic and environmental factors. Epidemiologic studies have furthered our understanding of these risk factors but remain limited by residual confounding and potential for reverse causation, particularly in MS where time of disease onset is not known. Mendelian randomization (MR) uses genetic variants to study the causal effect of modifiable exposures on an outcome. This method avoids some of the limitations of classical epidemiology and can strengthen causal inference...

Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system characterized by exacerbations of neurological dysfunction due to inflammatory demyelination. Neurologic symptoms typically present in young adulthood and vary based on the site of inflammation, though weakness, sensory impairment, brainstem dysfunction and vision loss are common. MS occurs more frequently in women and its development is complex-genetics, hormones, geography, vitamin D, and viral exposure all play roles. Early MS is characterized by relapsing-remitting course and inflammation of the white matter though as patients age, the disease often transitions to a pathologically distinct secondary progressive phase with gradual disability accrual affecting gait, coordination and bladder function...

Pediatric-onset multiple sclerosis (POMS), once thought to be rare, is now being diagnosed in increasing numbers in children. Despite improvements to diagnostic criteria, the diagnosis and management of POMS remains challenging. The aim of this study is to retrospectively describe a growing POMS patient population seen at a single center over a 13 year period. Epidemiologic, clinical, neuroimaging, laboratory features and therapeutic management and outcome data were collected and analyzed. These data support associations between MS and environmental triggers such as obesity and vitamin D deficiency...

Numerous observational studies have suggested that there is a correlation between the level of serum vitamin D and MS risk and disease activity. To explore this hypothesis, a literature search of large, prospective, observation studies, epidemiological studies, and studies using new approaches such as Mendelian randomization was conducted. Available data and ongoing research included in this review suggest that the level of serum vitamin D affects the risk of developing MS and also modifies disease activity in MS patients...

Vitamin D research has gained increased attention in recent times due to its roles beyond bone health and calcium homeostasis, such as immunomodulation. In some parts of the brain and on immune cells, vitamin D hydroxylating enzymes and its receptors are located. Epidemiological evidence demonstrates that deficiency of Vitamin D is relevant for disease risk and course in multiple sclerosis (MS) and presumably also in neuromyelitis optica spectrum disorders (NMOSD), Parkinson's disease (PD), and Alzheimer's disease (AD)...

Background: Insufficient received ultraviolet B radiation (UV) is regarded as the main environmental risk factor (RF) for MS in vitamin D deficiency hypothesis. Nevertheless, geomagnetic disturbance (GMD) has also been proposed as a potential trigger for MS in GMD hypothesis. The aim of this study was to investigate which of these mentioned RF is correlated with long-term ultradecadal MS incidence. Methods: After a systematic search, long-term incidence reports of the United Kingdom (UK), Denmark, Tayside County, Nordland County, the Orkney, and Shetland Islands were selected for this retrospective time-series study...

Meaningful symptom management can have a profound impact on quality of life. It can challenge time parameters during clinic, and therefore thought should be given to strategies that can improve efficiency and thereby make the undertaking more tenable. For any given symptom, the building blocks of care, such as vitamin D status, exercise/physical therapy, nutrition, and stress management, and ensuring disease-modifying therapy coverage, should be maximized. For each symptom, there are pharmacologic and nonpharmacologic interventions...

Several studies have investigated the association of different HLA antigens with multiple sclerosis (MS). However, only few studies have considered the association of high resolution HLA type and MS, with none yet from Saudi Arabia. The aim of this study was to investigate the association of HLA class II alleles with MS in the Saudi population. We used next generation sequencing to investigate HLA association with MS. This study was conducted at King Abdulaziz Medical City in Riyadh, Saudi Arabia. We found that several HLA-DRB1 and DQB1 alleles were associated with MS...

Vitamin D receptor (VDR) polymorphisms have been inconsistently investigated in multiple sclerosis (MS). However, published studies demonstrated differences concerning design and effect size. A meta-analysis is necessary to determine the magnitude of the association between VDR polymorphisms and MS risk. The aim of the current study was to quantify the magnitude of the association between BsmI, FokI, ApaI, and TaqI VDR polymorphisms and MS risk. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a systematic search and meta-analysis of the VDR gene polymorphisms and the risk of MS...

Various kinds of immune cells -including dendritic cells, macrophages, T cells and B cells- express the vitamin D receptor and 1α-hydroxylase(CYP27B1). In vitro studies have shown the anti-inflammatory effect of 1,25-dihydroxyvitamin D:the active form of vitamin D. As vitamin D deficiency spread in our society, epidemiological studies have established the association between vitamin D deficiency and incidence or progression of several inflammatory diseases, including rheumatoid arthritis(RA), systemic lupus erythematosus(SLE), and multiple sclerosis(MS)...

Central to the understanding of the relationships between diet, gut microbiota, and vitamins D and A in multiple sclerosis is low-grade inflammation, which is involved in all chronic inflammatory diseases and is influenced by each of the above effectors. We show that food components have either proinflammatory or anti-inflammatory effects and influence both the human metabolism (the "metabolome") and the composition of gut microbiota. Hypercaloric, high-animal-fat Western diets favor anabolism and change gut microbiota composition towards dysbiosis...
