BACKGROUND: It seems that gene-environment interaction play most important role in Multiple Sclerosis development. Increasing the incidence and prevalence of MS during the recent decades in the low prevalence area such as Iran is explained better by environment factors. Environmental Risk Factors in Multiple Sclerosis (the 'EnvIMS-Q') is a 6-page self-administered questionnaire for case control studies. OBJECTIVES: the objectives of study are validation and adaptation of the EnvIMS-Q' then development of a Persian version for case control studies in Persian population...

Chemokine receptor CXCR5 is highly expressed in B-cells and under normal conditions is involved in their migration to specific areas of secondary lymphoid organs. B-cells are known to play an important role in various autoimmune diseases including multiple sclerosis (MS) where areas of demyelinating lesions attract B-cells by overexpressing CXCL13, the CXCR5 ligand. In this study, we aimed to determine the functional significance of single-nucleotide polymorphism rs630923 (A/C), which is located in cxcr5 gene promoter, and its common allele is associated with increased risk of MS...

Multiple sclerosis (MS) is a chronic demyelinating disease of central nervous system regarded as one of the most common causes of neurological disability in young adults. The exact etiology of MS is not yet known, although epidemiological data indicate that both genetic susceptibility and environmental exposure are involved. A poor vitamin D status has been proposed as the most attractive environmental factor. Several evidence have highlighted the importance of mutations in vitamin D-regulating genes for vitamin D status...

In the past 20 years the treatment scenario of multiple sclerosis has radically changed. The increasing availability of effective disease-modifying therapies has shifted the aim of therapeutic interventions from a reduction in relapses and disability accrual, to the absence of any sign of clinical or MRI activity. The choice for therapy is increasingly complex and should be driven by an appropriate knowledge of the mechanisms of action of the different drugs and of their risk-benefit profile. Because the relapsing phase of the disease is characterised by inflammation, treatment should be started as early as possible and aim to re-establish the normal complex interactions in the immune system...

Autoimmune diseases often share common susceptibility genes. Most genetic variants associated with susceptibility to systemic lupus erythematosus are also associated with other autoimmune diseases. The X-linked variant rs2294020 is positioned in exon 7 of the CCDC22 gene. The encoded protein functions in the regulation of NF-κB, a master regulator in immune response. The aim of this study is to investigate whether the rs2294020 polymorphism may be a general susceptibility factor for autoimmunity. We evaluated case-control association between the occurrence of rs2294020 and different autoimmune diseases, including new data for systemic lupus erythematosus and previous genome-wide association studies (GWAS) (though most did not analyse the X chromosome) of psoriasis, celiac disease, Crohn's disease, ulcerative colitis, multiple sclerosis, vitiligo, type-1 diabetes, rheumatoid arthritis, and ankylosing spondylitis...

Multiple sclerosis (MS) is a chronic autoimmune disease that affects the central nervous system (CNS) characterized by demyelination and neurodegeneration, driven by a Th17/Th1-immune response, which afflicts mainly young women. Although MS causes are not completely known, it is notorious that the disease is characterized by an extended focal degradation of the myelin sheath, with ulterior axon and neuronal damage. Lipid molecules play a main dual role in MS, both as target molecules of myelin destruction and as mediators of inflammation...

BACKGROUND: Health-related quality of life (QOL) is a key outcome for people with multiple sclerosis (MS). While modifiable lifestyle factors, like smoking, physical activity and vitamin D, have strong associations with development and progression of MS, few studies have examined such associations with QOL. METHODS: Using patient-reported data from 2312 people with MS from 54 countries, regression models explored associations of socio-demographic, therapeutic and lifestyle factors with QOL, using the Multiple Sclerosis Quality of Life-54 (MSQOL-54)...

In addition to muscle stiffness and increasing mobility restrictions, symptoms commonly associated with multiple sclerosis (MS) spasticity are spasms, sleep disturbances, pain, fatigue and bladder dysfunction. Treatment options include trigger factor avoidance, physiotherapy and antispasticity medication. Oral antispasticity agents commonly used in Germany are baclofen, tizanidine and gabapentin, but physician and patient satisfaction with their effectiveness is low. Over the past few years, randomized controlled trials, observational studies and registry data have demonstrated the positive risk:benefit profile of add-on 9-delta-tetra-hydrocannabinol:cannabidiol oromucosal spray for moderate-to-severe resistant MS spasticity...

Consensus definitions for acute demyelinating syndromes in children have led to increased recognition of pediatric multiple sclerosis and improved our understanding of its pathogenesis, epidemiology and treatment. An estimated 2-10% of MS patients experience their first clinical symptom in childhood. Multiple genetic and environmental risk factors have been identified in the pathogenesis of pediatric MS, although further research to determine their interplay is required. Clinical trials of emerging disease-modifying therapies in children are nearing completion...

We performed comparative analyses of the genotype distribution and allelic frequencies of the rs948854 polymorphism (G/A) in the galanin gene's promoter in patients with multiple sclerosis (MS) and in healthy matched controls. In total 111 patients and 115 control subjects were included. The analyses revealed that the presence of the minor allele (G) increased susceptibility to MS in men (OR = 2.49, P = 0.008) but not in women. The presence of the G allele in men was also significantly associated with the late onset of MS...

Biologics are substances made from a living organism or its products. These include genes, proteins (eg, antibodies, receptors, enzymes, inhibitors), recombinant proteins, and fusion proteins. Biologics often are produced using recombinant DNA technology. For example, monoclonal antibodies are produced by inserting human genes into immortalized cell cultures, which then produce the gene product (ie, an antibody) in large quantity. Another approach is to fuse genetic material from nonhuman sources (eg, mice) with human genetic material...

INTRODUCTION: Depressive symptoms occur frequently in people with Multiple Sclerosis (MS) and rates of suicide ideation are higher than the general population. There is evidence for a direct association between disability and depression, disability and suicide ideation, and depression and suicide ideation in MS. However, the relationship between all three, i.e. the mediating role of depression between disability and suicidal ideation, has not been investigated. Exploring this relationship could highlight risk factors, alerting clinicians to the need for timely intervention...

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disorder of the central nervous system wherein, after an initial phase of transient neurological defects, slow neurological deterioration due to progressive neuronal loss ensues. Age is a major determinant of MS progression onset and disability. Over the past years, several mechanisms have been proposed to explain the key drivers of neurodegeneration and disability accumulation in MS. However, the effect of commonly encountered age-related cerebral vessel disease, namely small vessel disease (SVD), has been largely neglected and constitutes the aim of this review...
