Vitamin D may suppress infections which lead to development of Multiple Sclerosis Steven R Brenner, None (16 August 2007) J Neurol Neurosurg Psychiatry 2008 I read the article with reference to the inverse relationship between multiple sclerosis clinical activity and deficiency of vitamin D by Soilu-Hannienen (1) with interest, and was considering what mechanism could be in play to cause such a relationship. 25-hydroxylated metabolites of vitamin D act as intracellular regulators of the synthesis and action of defensin (2) molecules against bacterial antigens, defensin being an endogenously synthesized antimicrobial substance (2). Human cathelicidin antimicrobial peptide gene is a target of vitamin D receptor and is strongly up-regulated by 1,25-dihydroxyvitamin D3, indicating vitamin D receptor and the 1,25-dihydroxyvitaminD3 regulate primate innate immunity (3)

Not enough vitamin D: health consequences for Canadians. Schwalfenberg G. Can Fam Physician. 2007 May;53(5):841-54. Review PMID: 17872747 Conclusion Low levels of VTD are considered a major public health problem in Canada, especially during the winter. Those with risk factors should be screened for low 25(OH)D levels and repletion therapy instituted if needed. Researchers have estimated that the oral dose of vitamin D3 to attain and maintain 25(OH)D levels >80 nmol/L is 2200 IU/d if baseline levels are 20 to 40 nmol/L, 1800 IU/d if levels are 40 to 60 nmol/L, and 1160 IU/d if levels are between 60 and 80 nmol/L.64 We need to ensure that patients have healthy blood levels of 25(OH)D to prevent levels of parathyroid hormone from rising and to maximize absorption of calcium, magnesium, and phosphate. Positive effects on bone are marginal at best unless patients consume at least 800 IU/d of VTD. The emerging and exciting role of the VTD receptor and the actions of VTD in maintaining health in other cell types have become more apparent during the last decade.

Vitamin D is a fat-soluble vitamin that is essential for maintaining normal calcium metabolism (1). Vitamin D3 (cholecalciferol) can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight, or it can be obtained from the diet. Plants synthesize ergosterol, which is converted to vitamin D2 (ergocalciferol) by ultraviolet light. Vitamin D2 is less active in birds than vitamin D3 and may also be less active in humans (2). When exposure to UVB radiation is insufficient for the synthesis of adequate amounts of vitamin D3 in the skin, adequate intake of vitamin D from the diet is essential for health.

Expression of the multiple sclerosis-associated MHC class II Allele HLA-DRB1*1501 is regulated by vitamin D.\nRamagopalan SV, Maugeri NJ, Handunnetthi L, Lincoln MR, Orton SM, Dyment DA, Deluca GC, Herrera BM, Chao MJ, Sadovnick AD, Ebers GC, Knight JC.\nPLoS Genet. 2009 Feb;5(2):e1000369.

Supplements of vitamin D at 'critical time periods' may be key to reducing the risk of multiple sclerosis, according to a new study from the UK and Canada. Researchers report that vitamin D may interact with a specific genetic component called HLA-DRB1*1501 that is known to increase the risk of multiple sclerosis by three-fold

This critical nutrient builds bones, helps fight infection and may protect against some cancers. Do we get enough?

"Pohjolan kitsas aurinko tarjoaa D-vitamiinia seuraavan kerran maaliskuussa. Talvella luustovitamiinit pitää tankata ruoasta tai purkista. Kala on D-vitamiininlähteistä parhaita. D on se aurinkovitamiini, jota jokainen muistaa lapsena napsineensa - onnekkaimmat Vitol-helmien tai peräti suklaan muodossa, karskimpien perheiden kasvatit kalanmaksaöljynä. Ilman D-vitamiinia ihmisen elimistö ei kykene käyttämään hyväkseen ruoasta tulevaa kalsiumia, ja se näkyy luustossa. Riisitauti on puutostautien klassikko, jota tavataan meillä yhä. Joka vuosi siihen sairastuu muutama pikkulapsi, jolle ei ole annettu D-vitamiinilisää. D-vitamiinin puute pehmentää aikuistenkin luustoa, mutta silloin taudin nimi on osteomalasia. D:n puutteen katsotaan olevan myös yksi osteoporoosin riskitekijöistä. - D-vitamiinin vajaus ei tunnu olossa eikä näy päälle, ennen kuin luut tosiaan alkavat pehmentyä. Omaa vitamiinitilannettaan kannattaa miettiä, jos ei syö lainkaan kalaa ja käyttää vain vähän D-vitaminoituja maitovalmisteita, toteaa dosentti Christel Lamberg-Allardt Helsingin yliopistosta."
