La alimentación influye en la mejora de la sintomatología de cualquier enfermedad, incluida la esclerosis múltiple (EM),la cual, se caracteriza por un proceso inflamatorio crónico, autoinmune del sistema nervioso central generando situaciones como inflamación, alteraciones; digestivas y mentales, discapacidad, y fatiga. El propósito de la presente revisión fue identificar la evidencia científica sobre los aspectos nutricionales que mejoran la progresión de EM. La metodología consistió en la búsqueda de literatura, en bases de datos electrónicas, referente a nutrición y esclerosis múltiple, principalmente entre los años 2015-2020. Entre los resultados de los aspectos nutricionales que mostraron eficacia en mejorar la progresión de EM, se encuentran el zinc, vitamina D, fibra, probióticos, aceite de pescado y de oliva, cacao, cúrcuma, y salmón. Existen evidencias del papel inmunomodulador del Zn y de la vitamina D en la inhibición de la producción de citocinas proinflamatorias. Niveles bajos de ambos componentes se asocian con mayor riesgo de padecer EM. Otros componentes de interés nutricional son la fibra y probióticos; producen ácidos grasos de cadena corta, con propiedades antiinflamatorias. La primera se conoce por su papel en la motilidad gastrointestinal y los segundos por su acción celular y molecular en procesos inflamatorios, y modulación del microbioma, por mencionar algunos. Los aspectos nutricionales antes mencionados pueden contribuir a modular la inflamación y mejorar la fatiga. Finalmente, este documento genera un panorama importante para continuar con la investigación referente a la influencia de la alimentación en pacientes con EM. Diet influences the improvement of the symptoms of any disease, including multiple sclerosis (MS), which is characterized by a chronic, autoimmune inflammatory process of the central nervous system generating situations such as inflammation, mental and digestive alterations, disability and fatigue. The aim of this review was to identify the scientific evidence on the nutritional aspects that improve the progression of MS. The methodology consisted of searching literature, in electronic databases, referring to nutrition and multiple sclerosis, mainly between the years 2015-2020. The results of the nutritional aspects that showed effectiveness in improving the progression of MS, are zinc, vitamin D, fiber, probiotics, fish oil and olive oil, cocoa, turmeric and salmon. There is evidence of the immunomodulatory role of Zn and vitamin D in inhibiting the production of proinflammatory citokines. Low levels of both components are associated with an increased risk of MS. Other components of nutritional interest are fiber and probiotics; they produce short chain fatty acids, with anti-inflammatory properties. The first is known for its role in gastrointestinal motility and the second one for its cellular and molecular actions in inflammatory processes and the microbiome modulation, to name a few. The nutrition aspects mentioned above, can contribute to modulate inflammation and improve fatigue. Finally, this paper creates an important perspective to continue the investigation concerning the influence of diet in MS patients.

Genetic And Environmental Factors

Abstract Multiple sclerosis (MS) is a complex inflammatory disease of the central nervous system (CNS) resulting in neurological impairment and disability. There is evidence that adequate vitamin D levels may lower the risk of MS development. The aetiology of MS is complex and involves both genetic and environmental factors. In fact, not one but several genes are believed to lead to the disease. As for environmental factors, one of the most important risk factors is vitamin D deficiency, which, in turn, is closely related to gene polymorphisms that play a role in vitamin D metabolism and regulation. However, information about these gene polymorphisms is quite contradictory. The aim of this review is to discuss the association between some of the vitamin D-related gene variants and MS.

Methods Of Treatment

Multiple sclerosis (MS) is a multifactorial disease of the central nervous system (CNS) characterized by an inflammatory process and demyelination. The etiology of the disease is still not fully understood. Therefore, finding new etiological factors is of such crucial importance. It is suspected that the development of MS may be affected by oxidative stress (OS). In the acute phase OS initiates inflammatory processes and in the chronic phase it sustains neurodegeneration. Redox processes in MS are associated with mitochondrial dysfunction, dysregulation of axonal bioenergetics, iron accumulation in the brain, impaired oxidant/antioxidant balance, and OS memory. The present paper is a review of the current literature about the role of OS in MS and it focuses on all major aspects. The article explains the mechanisms of OS, reports unique biomarkers with regard to their clinical significance, and presents a poorly understood relationship between OS and neurodegeneration. It also provides novel methods of treatment, including the use of antioxidants and the role of antioxidants in neuroprotection. Furthermore, adding new drugs in the treatment of relapse may be useful. The article considers the significance of OS in the current treatment of MS patients.

Multiple Sclerosis (MS) is a chronic inflammatory autoimmune disease of the Central Nervous System (CNS). Genetic, epigenetic and environmental factors interact together, contributing to the complex pathogenesis of the disease. In the last decades, the role of hypovitaminosis D on MS risk was hypothesised. Several factors drive the regulation of vitamin D status, including genetics. The current review summarises the literature evidence on the association between vitamin D and MS, with a focus on the genetic polymorphisms in vitamin D-related genes. The variants of the genes codifying Vitamin D Receptor (VDR), Vitamin D Binding Protein (VDBP) and CYP enzymes have been investigated, but the findings are controversial. Only a few studies have addressed the role of DHCR7 polymorphisms in MS risk.

Disease Modifying Treatment

Abstract Multiple sclerosis (MS) is an inflammatory, demyelinating and neurodegenerative disease of the central nervous system with unknown etiology. Currently approved disease-modifying treatment modalities are immunomodulatory or immunosuppressive. While the applied drugs reduce the frequency and severity of the attacks, their efficacy to regenerate myelin membranes and to halt disease progression is limited. To achieve such therapeutic aims, understanding biological mechanisms of remyelination and identifying factors that interfere with remyelination in MS can give respective directions. Such a perspective is given by the emerging functional profile of galectins. They form a family of tissue lectins, which are potent effectors in processes as diverse as adhesion, apoptosis, immune mediator release or migration. This review focuses on endogenous and exogenous roles of galectins in glial cells such as oligodendrocytes, astrocytes and microglia in the context of de- and (re)myelination and its dysregulation in MS. Evidence is arising for a cooperation among family members so that timed expression and/or secretion of galectins-1, -3 and -4 result in modifying developmental myelination, (neuro)inflammatory processes, de- and remyelination. Dissecting the mechanisms that underlie the distinct activities of galectins and identifying galectins as target or tool to modulate remyelination have the potential to contribute to the development of novel therapeutic strategies for MS.

Multiple sclerosis (MS) is a chronic neurological disease affecting the central nervous system (CNS). The disease is characterised by demyelination and axonal loss caused by abnormal immunological responses resulting in accumulating neurological disabilities. MS is considered a complex disease, with both genetic and environmental factors contributing to the pathogenesis. In this study, we have investigated the genetic role of the myeloperoxidase (MPO) gene encoding myeloperoxidase in MS. MPO is an enzyme found in myeloid cells which catalyses the production of hypochlorus acid, a potent microbicidal agent. It also plays an important role in inflammatory processes, where migrating neutrophiles may release active MPO and cause tissue damage. In this study, we investigated two polymorphisms located in the promotor region of the MPO gene, known to influence the expression of MPO, in a large case/control material consisting of 871 Swedish MS patients and 532 Swedish healthy controls. No association was observed with risk of MS. Multiple Sclerosis 2007; 13: 697-700. http://msj.sagepub.com

This paper looks at the environmental role of vitamin D and solar radiation as risk reduction factors in autoimmune disease. Five diseases are considered: multiple sclerosis, type 1 diabetes, rheumatoid arthritis, autoimmune disease of the thyroid, and inflammatory bowel disease. Clinical relevant studies and factors that may indicate evidence that autoimmune disease is a vitamin D-sensitive disease are presented. Studies that have resulted in prevention or amelioration of some autoimmune disease are discussed. An example of the utility of supplementing vitamin D in an unusual autoimmune disease, idiopathic thrombocytic purpura, is presented.

Peripheral Immune Cells

Multiple sclerosis (MS) is an unpredictable disease of the central nervous system. The cause of MS is not known completely, and pathology is specified by involved demyelinated areas in the white and gray matter of the brain and spinal cord. Inflammation and peripheral tolerance breakdown due to Treg cell defects and/or effector cell resistance are present at all stages of the disease. Several invading peripheral immune cells are included in the process of the disease such as macrophages, CD8+ T cells, CD4+ T cells, B cells, and plasma cells. Trace elements are known as elements found in soil, plants, and living organisms in small quantities. Some of them (e.g., Al, Cu, Zn, Mn, and Se) are essential for the body’s functions like catalysts in enzyme systems, energy metabolism, etc. Al toxicity and Cu, Zn, and Se toxicity and deficiency can affect the immune system and following neuron inflammation and degeneration. These processes may result in MS pathology. Of course, factors such as lifestyle, environment, and industrialization can affect levels of trace elements in the human body.

Multiple studies have provided evidence for an association between reduced sun exposure and increased risk of multiple sclerosis (MS), an association likely to be mediated, at least in part, by the vitamin D hormonal pathway. Herein, we examine whether the vitamin D receptor ( VDR), an integral component of this pathway, influences MS risk in a population-based sample where winter sun exposure in early childhood has been found to be an important determinant of MS risk. Three polymorphisms within the VDR gene were genotyped in 136 MS cases and 235 controls, and associations with MS and past sun exposure were examined by logistic regression. No significant univariate associations between the polymorphisms, rs11574010 ( Cdx-2A > G), rs10735810 ( Fok1T >  C), or rs731236 ( Taq1C > T) and MS risk were observed. However, a significant interaction was observed between winter sun exposure during childhood, genotype at rs11574010, and MS risk ( P = 0.012), with the ‘G’ allele conferring an increased risk of MS in the low sun exposure group (≤2 h/day). No significant interactions were observed for either rs10735810 or rs731236, after stratification by sun exposure. These data provide support for the involvement of the VDR gene in determining MS risk, an interaction likely to be dependent on past sun exposure.

Genetic And Environmental Factors

Multiple sclerosis (MS) is an inflammatory, autoimmune, demyelinating, and degenerative central nervous system disease. Even though the etiology of MS has not yet been fully elucidated, there is evidence that genetic and environmental factors interact to cause the disease. Among the main environmental factors studied, those more likely associated with MS include certain viruses, smoking, and hypovitaminosis D. This review aimed to determine whether there is evidence to recommend the use of vitamin D as monotherapy or as adjunct therapy in patients with MS. We searched PUBMED, EMBASE, COCHRANNE, and LILACS databases for studies published until September 9 th , 2013, using the keywords “multiple sclerosis”, “vitamin D”, and “clinical trial”. There is no scientific evidence up to the production of this consensus for the use of vitamin D as monotherapy for MS in clinical practice.
