A new study by researchers at the University of Colorado Denver and Massachusetts General Hospital (MGH) shows vitamin D plays a vital role in reducing the risk of death associated with older age. The research, just published in the Journal of the American Geriatrics Society, evaluated the association between vitamin D levels in the blood and the death rates of those 65 and older. The study found that older adults with insufficient levels of vitamin D die from heart disease at greater rates that those with adequate levels of the vitamin.

Research finds people with gene variant who lack vitamin D, produced from sun exposure, can develop condition

Our vision: To significantly improve the health of Canadians through the preventative health strategy of maintaining optimum vitamin D blood levels.

"D-vitamiini näyttää ehkäisevän B-solulymfooman (imukudossyöpä) etenemistä ja potilaiden kuolemaa, ilmenee uudesta Mayo-klinikan ja Iowan yliopiston tutkimuksesta. Se esitettiin tällä viikolla New Orleansissa pidetyssä veritauteihin erikoistuneiden lääkäreiden vuosikokouksessa (American Society of Hematology). Taudin suomalaisissa hoitosuosituksissa D-vitamiinia ei mainita sanallakaan. "Nämä havainnot ovat toistaiseksi vahvimmat näytöt D-vitamiinin merkityksestä syövän ennusteessa", tulkitsee tutkimusta johtanut endokrinologi Matthew Drake (Mayo Clinic, Rochester, USA). Hän kaipaa lisää tutkimusta tästä aiheesta, sillä D-vitamiinin anto ruoan lisänä saattaa auttaa taudin hoidossa. "

ScienceDaily (Dec. 5, 2009) - A new study has found that the amount of vitamin D in patients being treated for diffuse large B-cell lymphoma was strongly associated with cancer progression and overall survival. The results will be presented at the annual meeting of the American Society of Hematology in New Orleans. Also, several recent reports have concluded that vitamin D deficiency is associated with poor outcomes in other cancers, including breast, colon and head and neck cancer. This is the first study to look at lymphoma outcome

"Maybe vitamin D isn't the answer after all. Not only does the above statement ring true, it's also the title of a recent post on "Dr. Len's Cancer Blog" - a website written by Dr. Len Lichtenfeld, Deputy Chief Medical Officer for the national office of the American Cancer Society, in order to facilitate communication with the public on important issues related to cancer.

A phase 2 trial exploring the effects of high-dose (10,000 IU/day) vitamin D(3) in breast cancer patients with bone metastases. Amir E, Simmons CE, Freedman OC, Dranitsaris G, Cole DE, Vieth R, Ooi WS, Clemons M. Cancer. 2009 Nov 13. [Epub ahead of print] PMID: 19918922 DOI: 10.1002/cncr.24749 METHODS: Patients with bone metastases treated with bisphosphonates were enrolled into this single-arm phase 2 study. Patients received 10,000 IU of vitamin D3 and 1000 mg of calcium supplementation each day for 4 months. The effect of this treatment on palliation, bone resorption markers, calcium metabolism, and toxicity were evaluated at baseline and monthly thereafter. CONCLUSIONS: Daily doses of 10,000 IU vitamin D3 for 4 months appear safe in patients without comorbid conditions causing hypersensitivity to vitamin D. Treatment reduced inappropriately elevated parathyroid hormone levels, presumably caused by long-term bisphosphonate use. There did not appear to be a significant palliative benefit nor any significant change in bone resorption. Cancer 2010. © 2009 American Cancer Society.

25-hydroxyvitamin D levels inversely associate with risk for developing coronary artery calcification. de Boer IH, Kestenbaum B, Shoben AB, Michos ED, Sarnak MJ, Siscovick DS. J Am Soc Nephrol. 2009 Aug;20(8):1805-12. Epub 2009 May 14. PMID: 19443637 doi: 10.1681/ASN.2008111157 "In conclusion, lower 25-hydroxyvitamin D concentrations associate with increased risk for incident CAC. Accelerated development of atherosclerosis may underlie, in part, the increased cardiovascular risk associated with vitamin D deficiency."
