Comparing 229 colorectal cancer cases with 343 controls, University of Hawaii researchers found serum 25-hydroxyvitamin D inversely associated with the disease: subjects above the lowest quintile of under 16.8 ng/mL had a 37 to 46 percent lower risk. The study was not a clinical trial.

Vitamin D could fight Crohn's disease
McGill researchers found vitamin D acts directly on the beta defensin 2 gene, which encodes an antibacterial peptide, and on NOD2, which alerts cells to invading bacteria and viruses. Lead author John White says the data suggest for the first time that vitamin D deficiency can contribute to Crohn's.

Multiple Sclerosis News: Drug, Vitamins and Sunshine
The FDA approved Ampyra on January 22 to improve walking in multiple sclerosis, with reported 10-30% gains in walking speed but side effects including seizures if overused. Separate studies point to nutrient shortfalls in MS patients and link low vitamin D to a higher risk of relapse.

Vitamin D May Cut Colon Cancer Risk
An EPIC analysis of 520,000 people in ten Western European countries, published in the BMJ, found those with the highest blood vitamin D were 40 percent less likely to be diagnosed with colorectal cancer. Levels above 75 nmol/L brought no further reduction.

Low vitamin D linked to MS relapse risk (press release)
In UCSF research on childhood-onset multiple sclerosis, each 10 ng/mL rise in blood vitamin D corresponded to a 34 percent lower rate of later relapses. Lead author Ellen Mowry calls it the first look at vitamin D and disease course, and says it justifies a trial of supplementation.

CDC Releases Swine Flu Vaccine Statistics
As of January 2, about 61 million Americans, a fifth of the population, had received the 2009 H1N1 vaccine, the CDC reported, including 29.4 percent of children aged 6 months to 18 years. All key flu indicators declined during the first week of January.

Calcium, Vitamin D used Together Cut Fracture Risk
A Copenhagen meta-analysis of seven trials covering 68,517 people averaging age 70 found vitamin D alone did not change fracture risk, while vitamin D with calcium cut overall fractures 8% and hip fractures 16%. The authors disclosed fees from major drug makers.

Vitamin D linked to cardiac deaths in blacks
Kevin Fiscella's team analysed 15,000 U.S. adults and found the most severe vitamin D deficiency came with a 40% higher risk of cardiac death, with risk falling as vitamin D levels rose. Black participants were 38% more likely to die than whites.

Depression News: Sleep, vitamin D help depression
A small trial in Applied Nursing Research gave vitamin D3 to nine women with serum levels below 40 ng/mL. The six who finished raised their levels by an average 27 ng/mL and dropped their Beck Depression Inventory-II scores by about 10 points, which the authors call suggestive.
Nutrition
Vitamin D deficiency linked to high risk of dementia
A Neurology study of 340 people aged 65 to 99 found those with insufficient vitamin D were twice as likely to have dementia, Alzheimer's or stroke. After adjustment, insufficiency was tied to 130 percent higher all-cause dementia risk and 100 percent higher stroke risk.

Vitamin D may have an effect on prostate cancer
Researchers compared 122 prostate cancer patients with 130 matched controls in southern China and found one vitamin D receptor variant, BsmI, tracked with prostate cancer risk. They conclude such polymorphisms may be potential risk factors.

More Vitamin D Studies of Interest
The Vitamin D Council newsletter covers Bruce Hollis and Carol Wagner's trial of about 500 pregnant women at 400, 2,000 or 4,000 IU a day. The highest dose caused no adverse events but left newborns averaging 27 ng/ml, and mothers needed 40 ng/ml to maximize activated vitamin D.

Heart failure linked to gene variant affecting vitamin D activation
Among 617 patients from the Marshfield Clinic Personalized Medicine Project, those with high blood pressure who carried a variant in CYP27B1, a gene needed to activate vitamin D, were twice as likely to have congestive heart failure. Co-author Robert Simpson says larger studies must confirm it.

Vitamin D deficiency may raise risk of type 1 diabetes
Borkar and colleagues in India measured vitamin D in 50 children within a week of a type 1 diabetes diagnosis and 50 others: averages were 20.02 against 26.16 ng/mL, with 58% of the diabetic children deficient against 32%. They call for supplementation trials.

Vitamin D cuts risk of cardiovascular disease
Among 27,686 patients aged 50 and older with no prior cardiovascular disease, those with very low vitamin D were 77 percent more likely to die, 45 percent more likely to have coronary artery disease and 78 percent more likely to have a stroke than those with normal levels.
Diabetes
Vitamin D deficiency may boost type 1 diabetes risk
A case-control study in Pediatric Diabetes compared 50 Indian children newly diagnosed with type 1 diabetes to 50 without: average vitamin D was 20 ng/mL against 26, and deficiency appeared in 58 percent versus 32 percent. A Qatari study found a smaller but significant gap.

Vitamin D deficiency key contributor to end-stage renal disease
Analysing data on 13,000 Americans, Michal Melamed's team found those with the lowest 25(OH)D levels were 2.6 times as likely to end up on dialysis, and that vitamin D deficiency accounted for about 58 percent of the higher ESRD risk in African Americans. The link is associational.

Vitamin D supplements taken in early life prevent type 1 diabetes*
In Lancet data on children of 12,055 Finnish women due to give birth in 1966, those who regularly took vitamin D supplements were 88 percent less likely to have type 1 diabetes than those who took none, and children suspected of rickets were three times as likely to develop it.
