    Low vitamin D serum level is related to severe fibrosis and low responsiveness to IFN-based therapy in genotype 1 chronic hepatitis C
    Salvatore Petta et al.
    Hepatology, Volume 9999 Issue 999A, Page NA. Published Online: 4 Dec 2009
    DOI: 10.1002/hep.23489

    Conclusions:
    G1 CHC patients had low 25(OH)D serum levels, possibly due to reduced CYP27A1 expression. Low vitamin D is linked to severe fibrosis and low SVR on IFN-based therapy. (HEPATOLOGY 2010.)

    Hypovitaminosis D in an Italian population of healthy subjects and hospitalized patients.
    Romagnoli E, Caravella P, Scarnecchia L, Martinez P, Minisola S.
    Br J Nutr. 1999 Feb;81(2):133-7.
    PMID: 10450331

    The results of the present study emphasize the importance of 25-hydroxyvitamin D measurement, and the need to increase vitamin D intake in Italy; foodstuff fortification and supplement use must be considered in order to prevent negative effects of vitamin D deficiency on skeletal integrity.

    All hospitalized patients, both in summer and in winter,
    are characterized by the highest prevalence of hypovitaminosis
    D, especially the older patients. Medical
    inpatients may be at risk for vitamin D deficiency,

Vitamin D levels associated with survival in lymphoma patients - 0 views

  •  
    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

    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.

    Safety of vitamin D3 in adults with multiple sclerosis.
    Kimball SM, Ursell MR, O'Connor P, Vieth R.
    Am J Clin Nutr. 2007 Sep;86(3):645-51.
    PMID: 17823429

    Conclusions: Patients' serum 25(OH)D concentrations reached twice the top of the physiologic range without eliciting hypercalcemia or hypercalciuria. The data support the feasibility of pharmacologic doses of vitamin D3 for clinical research, and they provide objective evidence that vitamin D intake beyond the current upper limit is safe by a large margin.

    VITAMIN D LOWERS C-REACTIVE PROTEIN (CRP)
    Van den Berghe and colleagues at the University of Leuven in Belgium appear to be the first to show that simple, natural and cheap vitamin D (cholecalciferol) lowers CRP in critically ill patients. Even small amounts of cholecalciferol (500 IU) lowered CRP by more than 25% in a small group of critically ill patients. Another marker of inflammation (IL-6) was reduced even more. The researchers also found that critically ill patients were profoundly deficient in vitamin D.

    "May 19, 2008 (Orlando, Florida) - A new study shows that a proactive vitamin D treatment plan should be considered when caring for all osteoporosis patients, and that such treatment might help decrease the likelihood of developing vitamin D deficiency.

    Vitamin D deficiency is widespread among patients being treated for osteoporosis, and such deficiency should be treated aggressively, according to the findings presented here at the American Association of Clinical Endocrinologists 17th Annual Meeting and Clinical Congress."

    Cholecalciferol supplementation resulted in a 31% greater increase in total HPLC-measured 25OHD (p=0.010) and 52% greater rise in RIA-measured 25OHD (p<0.001) of supplementation dose with than ergocalciferol equivalent an>0.05). In vitamin D-insufficient hip fracture patients, supplementation with cholecalciferol 1000 IU/day for three months was more effective in increasing serum 25OHD than an equivalent dose of ergocalciferol. However, the lack of difference in PTH lowering between calciferol treatments raises questions about the biological importance of this observation.

    Severe vitamin D deficiency in Swiss hip fracture patients.
    Bischoff-Ferrari HA, Can U, Staehelin HB, Platz A, Henschkowski J, Michel BA, Dawson-Hughes B, Theiler R.
    Bone. 2008 Mar;42(3):597-602. Epub 2007 Nov 28.
    PMID: 18180211

    BACKGROUND: Most clinical guidelines for the prevention of hip fractures recommend 800 IU vitamin D per day. This dose shifted serum 25-hydroxyvitamin D levels (25(OH)D) in previous studies to between 60 and 100 nmol/l. AIM: To measure 25(OH)D levels and prevalence of vitamin D supplementation in individuals age 65+ with acute hip fracture. METHODS: 222 consecutive hip fracture patients were investigated over a 12 month period. Mean age of patients was 86 years and 77% were women. RESULTS: Mean serum 25(OH)D levels were low among hip fracture patients admitted from home (34.6 nmol/l), from assisted living (27.7 nmol/l), and from nursing homes (24 nmol/l). Severe vitamin D deficiency below 30 nmol/l was present in 60%, 80% were below 50 nmol/l, and less than 4% reached desirable levels of at least 75 nmol/l. Consistently, only 10% of hip fracture patients had any vitamin D supplementation on admission to acute care with significantly higher 25(OH)D levels among individuals supplemented with 800-880 IU/day (63.5 nmol/l). Controlling for age and gender, vitamin D supplementation, type of dwelling, and season were independently and significantly associated with 25(OH)D levels. CONCLUSION: These data provide evidence that current guidelines for the prevention of hip fractures need further effort to be translated into clinical practice.

    Measurement of vitamin D levels in inflammatory bowel disease patients reveals a subset of Crohn's disease patients with elevated 1,25-dihydroxyvitamin D and low bone mineral density.
    Abreu MT, Kantorovich V, Vasiliauskas EA, Gruntmanis U, Matuk R, Daigle K, Chen S, Zehnder D, Lin YC, Yang H, Hewison M, Adams JS.
    Gut. 2004 Aug;53(8):1129-36.
    PMID: 15247180
    doi: 10.1136/gut.2003.036657.

    Conclusions: These data demonstrate that elevated 1,25(OH)2D is more common in CD than previously appreciated and is independently associated with low bone mineral density. The source of the active vitamin D may be the inflamed intestine. Treatment of the underlying inflammation may improve metabolic bone disease in this subgroup of patients.

    Osteoporos Int. 2005 Dec;16(12):2018-24. Epub 2005 Aug 24.
    PMID: 16133642

    Half of the patients with a hip fracture suffered from hypovitaminosis D. The situation was worst in institutional and residential care, although there are personnel for taking care of vitamin D supplementation. In the late summer, one-third and in late winter two-thirds of the patients suffered from hypovitaminosis D. The geographical location of Finland indicates extensive efforts to increase the use of vitamin D supplements among elderly.

Vitamin D Levels Linked to Breast-Cancer Prognosis - GrassrootsHealth | Vitamin D Action - 0 views

  •  
    Women who are vitamin D deficient when they are diagnosed with breast cancer are more likely to have their disease spread and are more likely to die than women who have adequate vitamin D levels, new Canadian research says.

    The study found that women who were vitamin D deficient were 94 per cent more likely to have their cancer metastasize (spread) and 73 per cent more likely to die.

    The research was led by Dr. Pamela Goodwin, a breast cancer researcher at Mount Sinai Hospital in Toronto. The study analyzed blood samples and disease outcome from more than 500 women diagnosed with breast cancer between 1989 and 1995. Women were followed up for an average of 11 years.
