Vitamin D receptors and vitamin D metabolizing enzymes are present in the central nervous system. Calcitriol (the active vitamin D hormone) affects numerous neurotransmitters and neurotrophic factors, relevant for mental disorders. In the case of depressive disorders, considerable evidence supports a role of suboptimal vitamin D levels. However, the data are not conclusive and further studies are necessary. Especially, the relative importance of the pineal-melatonin system versus the vitamin D-endocrine system for the pathogenesis of seasonal affective disorders is presently unresolved. Two diagnoses, schizophrenia and autism, have been hypothetically linked to developmental (prenatal) vitamin D deficiency, however, also in adult patients, low levels have been reported, supporting the notion that vitamin D deficiency may not only be a predisposing developmental factor but also relate to the adult patients’ psychiatric state. Two cases are described, whose psychiatric improvement coincided with effective treatment of vitamin D deficiency.

Oz Researchers link low vitamin D to schizophrenia

Researchers say babies born with low vitamin D levels may have an increased risk of developing schizophrenia later in life.

The three-year study tested blood samples from babies in Denmark and found having low vitamin D levels doubles the risk of developing the disorder.

The findings could encourage pregnant women to get more sunshine or take a vitamin D supplement.

Professor John McGrath, from the Queensland Brain Institute, says the study is further evidence of vitamin D’s link to brain development.

“Many years ago we thought it was totally implausible to prevent schizophrenia, it seemed to be such a mysterious, poorly understood group of illnesses,” he said.

“I think this new result suggests that maybe it will be possible to prevent schizophrenia.”

In memory of her mother, J K Rowling’s £10m for MS

At 45, J K Rowling is now the same age as her mother was when she succumbed to the ravages of multiple sclerosis. Anne Rowling’s untimely death in1990 – five years before her daughter first gave the world Harry Potter – has had a profound and lasting influence on the writer, who has been a vocal champion for sufferers of the degenerative disease ever since.

J K Rowling admits she weeps every time she writes about her mother, who died from MS in 1990

Now the creator of the bespectacled boy wizard, one of the most lucrative film and publishing phenomena of modern times, is putting her considerable wealth behind the mission to find a cure for the disease.

It was announced yesterday that the author had donated £10m to build a new clinic which she hopes will one day “unravel the mysteries” of MS. As well as investigating the causes and treatment of the condition, helping doctors to slow and eventually reverse the symptoms of the illness, the new centre at Edinburgh University – which will bear her late mother’s name – is intended to become a world leader in research into other currently incurable neurological conditions such as Alzheimer’s, Parkinson’s and motor neurone disease.

The donation, one of the most generous that Ms Rowling has given to date and the largest ever received by Edinburgh University, comes a year after she resigned as a long-serving patron of the MS Society Scotland following a bitter row between the charity and its London headquarters over reorganisation plans.

But she has continued to support efforts to battle the condition, criticising the Scottish Medicines Consortium when it advised against prescribing the drug Tysabri on cost grounds, and giving substantial financial support to a new research unit also at Edinburgh University in 2007.

Ms Rowling, who is the seventh-richest person in Scotland with an estimated fortune of £519m, said her home city had already attracted some of the best clinicians and researchers in the field of neurodegeneration, and that the new clinic would put patients at the centre of any advances when it is completed next year. The Anne Rowling Regenerative Neurology Clinic will be based in a purpose-built premises next to the city’s Royal Infirmary.

“I have supported research into the cause and treatment of multiple sclerosis for many years now, but when I first saw the proposal for this clinic, I knew that I had found a project more exciting, more innovative, and, I believe, more likely to succeed in unravelling the mysteries of MS than any other I had read about or been asked to fund,” she said.

Anne Rowling was 34 when she first began to suffer from pins and needles in her arm, and was diagnosed with MS the following year. Five years later, she relied on a wheelchair every day.

“At first, life went on much as usual, perhaps too much as usual. My mother made few, if any, concessions to her illness,” Ms Rowling said, adding that she wept every time she wrote about her mother. “I saw her for the last time just before Christmas 1990. She was extremely thin and looked exhausted. I don’t know how I didn’t realise how ill she was.”

MS affects about 100,000 people in the UK, and Scotland has one of the highest rates of sufferers. While doctors know that the disease causes myelin, a protective layer surrounding nerve cells in the brain, to break down, leading to symptoms such as numbness, fatigue and weakness, the exact cause is still not understood.

Health Correspondent – The Scotsman

TAKING vitamin D during pregnancy and in the first few years of life could help reduce the risk of a wide ranges of illness, researchers have revealed, after finding new genetic links between diseases and the compound.

The latest study mapped how the so-called “sunshine vitamin” interacted with human DNA, finding more than 200 genes where it had a direct influence.

The results suggest that taking supplements in early life could help reduce the risk of several illnesses multiple sclerosis, Crohn’s disease and some types of cancer.

It is estimated that one billion people worldwide do not have enough vitamin D, the main source of which comes through exposure to sunlight.

Scotland has some of the highest rates of MS in the world, and this has been linked by some to the lack of sunlight.

Glasgow schoolboy Ryan McLaughlin, whose mother Kirsten has MS, launched a campaign to increase awareness of the importance of vitamin D supplements with a petition at the Scottish Parliament last year.

A poor diet can also lead to vitamin D deficiency, according to the study published in Genome Research.

Previous studies have suggested that vitamin D deficiency increases the risk of “autoimmune conditions” such as MS and rheumatoid arthritis.

Now researchers at Oxford University have shown the true extent to which vitamin D interacts with our DNA, potentially making it a factor in a whole host of diseases.

The researchers used new DNA sequencing technology to create a map of vitamin D “receptor binding” across the genome – our complete genetic make-up.

The vitamin D receptor is a protein activated by vitamin D, which attaches itself to DNA and so influences what proteins are made from our genetic code. The researchers found 2,776 “binding sites” for the vitamin D receptor along the genome.

These were concentrated near genes associated with susceptibility to conditions such as MS, Crohn’s disease, lupus and rheumatoid arthritis, and to cancers such as chronic lymphocytic leukaemia and colorectal cancer.

They also showed that vitamin D had a significant effect on the activity of 229 genes, including IRF8, previously associated with MS, and PTPN2, associated with Crohn’s disease and type 1 diabetes.

Dr Andreas Heger, from the Medical Research Council Functional Genomics Unit at Oxford, said: “Our study shows quite dramatically the wide-ranging influence that vitamin D exerts over our health.”

Professor George Ebers, senior researcher on the study, said the evidence for the link between vitamin D and some illnesses, such as MS and Type 1 diabetes, had already been found.

But he said before the latest study, the evidence linking vitamin D to lupus and colon cancer had not been so strong.

There could also be other illnesses linked to vitamin D deficiency which are not yet known about.

Dr Sreeram Ramagopalan, from the Wellcome Trust Centre for Human Genetics, said: “There is now evidence supporting a role for vitamin D in susceptibility to a host of diseases.

“Vitamin D supplements during pregnancy and the early years could have a beneficial effect on a child’s health in later life.

“Some countries such as France have instituted this as a routine public health measure.”

Coca-Cola sued over vitaminwater health claims

Saturday, August 21st, 2010 | Tags: , , , , , , , , ,

vitaminwater

Now here’s something you wouldn’t expect. Coca-Cola is being sued by a non-profit public interest group, on the grounds that the company’s vitaminwater products make unwarranted health claims. No surprise there. But how do you think the company is defending itself?

In a staggering feat of twisted logic, lawyers for Coca-Cola are defending the lawsuit by asserting that “no consumer could reasonably be misled into thinking vitaminwater was a healthy beverage.”

Does this mean that you’d have to be an unreasonable person to think that a product named “vitaminwater,” a product that has been heavily and aggressively marketed as a healthy beverage, actually had health benefits?

Or does it mean that it’s okay for a corporation to lie about its products, as long as they can then turn around and claim that no one actually believes their lies?

In fact, the product is basically sugar-water, to which about a penny’s worth of synthetic vitamins have been added. And the amount of sugar is not trivial. A bottle of vitaminwater contains 33 grams of sugar, making it more akin to a soft drink than to a healthy beverage.

Is any harm being done by this marketing ploy? After all, some might say consumers are at least getting some vitamins, and there isn’t as much sugar in vitaminwater as there is in regular Coke.

True. But about 35 percent of Americans are now considered medically obese. Two-thirds of Americans are overweight. Health experts tend to disagree about almost everything, but they all concur that added sugars play a key role in the obesity epidemic, a problem that now leads to more medical costs than smoking.

How many people with weight problems have consumed products like vitaminwater in the mistaken belief that the product was nutritionally positive and carried no caloric consequences? How many have thought that consuming vitaminwater was a smart choice from a weight-loss perspective? The very name “vitaminwater” suggests that the product is simply water with added nutrients, disguising the fact that it’s actually full of added sugar.

The truth is that when it comes to weight loss, what you drink may be even more important than what you eat. Americans now get nearly 25 percent of their calories from liquids. In 2009, researchers at the Johns Hopkins Bloomberg School of Public Health published a report in the American Journal of Clinical Nutrition, finding that the quickest and most reliable way to lose weight is to cut down on liquid calorie consumption. And the best way to do that is to reduce or eliminate beverages that contain added sugar.


Meanwhile, Coca-Cola has invested billions of dollars in its vitaminwater line, paying basketball stars, including Kobe Bryant and Lebron James, to appear in ads that emphatically state that these products are a healthy way for consumers to hydrate. When Lebron James held his much ballyhooed TV special to announce his decision to join the Miami Heat, many corporations paid millions in an attempt to capitalize on the event. But it was vitaminwater that had the most prominent role throughout the show.

The lawsuit, brought by the Center for Science in the Public Interest, alleges that vitaminwater labels and advertising are filled with “deceptive and unsubstantiated claims.” In his recent 55-page ruling, Federal Judge John Gleeson (U.S. District Court for the Eastern District of New York), wrote, “At oral arguments, defendants (Coca-Cola) suggested that no consumer could reasonably be misled into thinking vitamin water was a healthy beverage.” Noting that the soft drink giant wasn’t claiming the lawsuit was wrong on factual grounds, the judge wrote that, “Accordingly, I must accept the factual allegations in the complaint as true.”

I still can’t get over the bizarre audacity of Coke’s legal case. Forced to defend themselves in court, they are acknowledging that vitaminwater isn’t a healthy product. But they are arguing that advertising it as such isn’t false advertising, because no could possibly believe such a ridiculous claim.

I guess that’s why they spend hundreds of millions of dollars advertising the product, saying it will keep you “healthy as a horse,” and will bring about a “healthy state of physical and mental well-being.”

Why do we allow companies like Coca-Cola to tell us that drinking a bottle of sugar water with a few added water-soluble vitamins is a legitimate way to meet our nutritional needs?

Here’s what I suggest: If you’re looking for a healthy and far less expensive way to hydrate, try drinking water. If you want to flavor the water you drink, try adding the juice of a lemon and a small amount of honey or maple syrup to a quart of water. Another alternative is to mix one part lemonade or fruit juice to three or four parts water. Or drink green tea, hot or chilled, adding lemon and a small amount of sweetener if you like. If you want to jazz it up, try one-half fruit juice, one-half carbonated water.

If your tap water tastes bad or you suspect it might contain lead or other contaminants, get a water filter that fits under the sink or attaches to the tap.

And it’s probably not the best idea to rely on a soft drink company for your vitamins and other essential nutrients. A plant-strong diet with lots of vegetables and fruits will provide you with what you need far more reliably, far more consistently — and far more honestly

Researchers discover genetic link between immune system, Parkinson’s disease

Monday, August 16th, 2010 | Tags: , , , , , , , , , ,
Posted in Uncategorized

A team of researchers has discovered new evidence that Parkinson’s disease may have an infectious or autoimmune origin. “Common genetic variation in the HLA region is associated with late-onset sporadic Parkinson’s disease” appears online in Nature Genetics.

The study was conducted by the NeuroGenetics Research Consortium, an international team of researchers led by Haydeh Payami, research scientist at the New York State Department of Health Wadsworth Center. The clinical directors for the study were Dr. Cyrus Zabetian, associate professor of neurology at the University of Washington and VA Puget Sound Health Care System, Stewart Factor at Emory University and John Nutt at Oregon Health and Sciences University.

The research team studied more than 2,000 Parkinson’s disease patients and 2,000 healthy volunteers from clinics in Oregon, Washington, New York and Georgia, assessing clinical, genetic and environmental factors that might contribute to the development and progression of Parkinson’s disease and its complications. Some of the research subjects were tracked for nearly two decades.

“Over the years, there have been subtle hints that immune function might be linked to Parkinson’s disease” said Zabetian. “But now we have much more convincing evidence of this and a better idea of which parts of the immune system might be involved.”

In the study, researchers detected a new association with the HLA (human leukocyte antigen) region, which contains a large number of genes related to immune system function in humans. With the new findings, and link to HLA, researchers will now be encouraged to take a fresh look at the possible role of infections, inflammation and autoimmunity in Parkinson’s disease.

HLA genes are essential for recognizing foreign invaders from the body’s own tissues. Similarly, HLA molecules are supposed to recognize a body’s own tissue as itself and prevent immune reactions against them. But the system doesn’t always work perfectly. HLA genes are highly variable from individual to individual. Certain variants of the genes are associated with increased risk or protection against infectious disease, while other variants can induce autoimmune disorders in which the immune system attacks the body’s own tissues. Multiple sclerosis, a neurological disease caused by autoimmunity, is also associated with HLA-DR. The genetic variant that is associated with Parkinson’s disease is in the same region as the one associated with multiple sclerosis.

People who take non-steroidal anti-inflammatory drugs (NSAIDs, such as ibuprofen) have a reduced risk of developing Parkinson’s disease, which also supports an immune-related mechanism. The protective effect of NSAIDs is not the same for everyone, likely because of genetic differences, and NSAIDs can have side effects. Pursuing the connection between Parkinson’s disease and inflammation, especially in the context of variable genetic makeup, may lead to better, more selective drugs for treating Parkinson’s disease.

Consortium leaders recognize the study would not have been possible without the precious help from volunteer patients. “This type of research could not be done if it weren’t for the willing and dedicated individuals who volunteer as research subjects,” said Payami, who acknowledged that some study subjects participated for nearly two decades.

What’s next for the team? “Our results also pointed to several other genes that might play a role in developing Parkinson’s disease, and these findings need to be confirmed, so we have a lot of work ahead of us” said Zabetian. He and others in the consortium will now mine the data even more for gene-environment interactions, with a goal of finding environmental triggers and protectors to develop genetically-personalized therapeutics for treatment and prevention of Parkinson’s disease.

The study was funded by the National Institute of Neurological Disorders and Stroke and the Edmond J. Safra Global Genetic Consortium grant from the Michael J. Fox Foundation for Parkinson’s Disease Research.

US probes corruption in big pharmaceutical companies

Sunday, August 15th, 2010 | Tags: , , , , , , , , , , , ,
Posted in External News Articles, Uncategorized

The US Department of Justice is scrutinising payments by leading pharmaceuticals companies for hospitality, consultants, licensing agreements and charitable donations in markets around the world as part of a wide-ranging corruption probe.

GlaxoSmithKline, Pfizer, Bristol-Myers Squibb and Eli Lilly, among others, have disclosed being contacted by the DoJ and Securities and Exchange Commission in connection with the investigation. Merck, the US drugs group, announced last week that it had also been contacted and was co-operating with investigators.

An industry attorney familiar with the probe said that the DoJ was looking at whether pharma companies had ignored a “systematic risk” inherent in the global drugs business and ignored obligations under local and US anti-bribery law.

The highly regulated nature of the business, combined with the fact that healthcare officials in many non-US markets were government funded, made the industry a natural target for such a probe, the person added. The investigation is at a relatively early stage but is considered a priority for the DoJ.

While hospitality – including meals and all expenses-paid travel for conferences – has long been considered a potential risk for pharma groups, the DoJ’s probe is looking at all aspects of companies’ dealings in non-US markets, people familiar with the matter say. That includes the recruitment of physicians for clinical trials. In some markets, the same physicians may serve on regulatory boards that approve or deny drugs.

The DoJ declined to comment. But last November, Lanny Breuer, head of the DoJ’s criminal division, announced that investigators would be focusing on international corruption in the pharmaceuticals industry for “years”.
Mr Breuer warned a conference of pharmaceutical industry lawyers that prosecutors were gearing up for an investigation of international corruption in the sector. The drugs companies took notice.

That threat has now become a reality. Merck, AstraZeneca, Eli Lilly, Baxter, SciClone, and Bristol-Myers Squibb have in recent months received inquiries from the DoJ and the Securities and Exchange Commission in connection with an industry-wide bribery investigation.

GlaxoSmithKline, the UK drugmaker, told the Financial Times on Thursday that it too had received “inquiries” from US authorities, but that it disclosed the issue “reactively” only to selected reporters in April.

Pfizer, the world’s largest pharmaceutical group, said in February that it had voluntarily provided the DoJ and SEC with information concerning potentially improper payments outside the US and was exploring resolution of the matter.

There is perhaps no industry that is as vulnerable to violations of US anti-bribery laws as the pharmaceutical industry. In markets round the world, the companies deal, sometimes thousands of times in a single day, with doctors, clinicians, hospital operators and regulators who are considered under US law to be government officials, because they are employed by state-owned facilities.

Under the Foreign Corrupt Practices Act, the US anti-bribery law, companies may not offer items of value to foreign government officials for profit. One industry lawyer involved in the matter said global pharmaceutical companies operating in countries with state-run medical institutions deal with government officials at every turn of their business: whether it is seeking the go-ahead for a manufacturing site; obtaining drug licences; conducting clinical trials; importing drugs; selling and marketing drugs to physicians; or getting a product on to a hospital’s approved list.

“What most companies will find is that all of these areas are risky and, if they don’t train and educate their people, they are going to find themselves with issues. For example, if you have hired customs brokers, how do you know they aren’t bribing officials?” the attorney said.

According to the law firm Arnold & Porter, the DoJ is particularly interested in corrupt payments that may have influenced the reliability or integrity of data in clinical trials performed outside the US. A recent report by the Department of Health and Human Services found 80 per cent of marketing applications for drugs approved by the Food and Drug Administration in the US had relied on at least one foreign trial.

“Companies may find themselves facing critical legal issues if approval of products rested on the results of studies the DoJ deems corrupt,” Arnold & Porter said in an advisory letter to clients last month.

A person familiar with the investigation confirmed that clinical trials were one of several areas the DoJ was examining.

Alexandra Wrage, the president of Trace, a non-profit organisation that helps companies establish anti-corruption practices, said that alleged wrong doing at pharmaceutical companies could often centre on inappropriately lavish hospitality, such as wining and dining doctors from state-run hospitals at conferences in Bali or Monaco.

“What we hear is not that doctors are expecting cash. But that doctors are only going to give companies time [for meetings] in front of a meal or a training session,” said Ms Wrage. Such sessions often involve all-expenses-paid travel.

In the US, drugs companies are also coming under more intense scrutiny for their interactions with doctors. Pfizer in April disclosed that it paid $35m over six months to 4,500 doctors in private practice for education and the development and marketing of new drugs – payments that are legal in the US.

But legal experts familiar with the inquiries say they expect that the DoJ is examining egregious behaviour that smells of bribery.

Study CONFIRMS raising vitamin D levels could reduce MS relapses by 50%

Higher 25-hydroxyvitamin D is associated with lower relapse risk in multiple sclerosis.

Abstract

OBJECTIVE: A protective association between higher vitamin D levels and the onset of multiple sclerosis (MS) has been demonstrated; however, its role in modulating MS clinical course has been little studied. We investigated whether higher levels of serum 25-hydroxyvitamin D (25-OH-D) were associated with a lower risk of relapses in people with MS.

METHODS: We conducted a prospective cohort study of 145 participants with relapsing-remitting MS from 2002 to 2005. Serum 25-OH-D levels were measured biannually, and the hazard of relapse was assessed using survival analysis.

RESULTS: There was an inverse linear relationship between 25-OH-D levels and the hazard of relapse over the subsequent 6 months, with hazard ratio (HR) 0.91 (95% confidence interval [CI]: 0.85-0.97) per 10nmol/l increase in 25-OH-D level (p = 0.006). When variation due to timing of blood collection was removed by estimating 25-OH-D at the start of each season, this association persisted, with HR 0.90 (95% CI, 0.83-0.98) per 10nmol/l increase (p = 0.016). Taking into account the biological half-life of 25-OH-D, we estimated 25-OH-D at monthly intervals, resulting in a slightly enhanced association, with HR 0.88 (95% CI, 0.82-0.95) per 10nmol/l increase (p = 0.001). Adjusting for potential confounders did not alter these findings.

INTERPRETATION: In this prospective population-based cohort study, in a cohort largely on immunomodulatory therapy, higher 25-OH-D levels were associated with a reduced hazard of relapse. This occurred in a dose-dependent linear fashion, with each 10nmol/l increase in 25-OH-D resulting in up to a 12% reduction in risk of relapse. Clinically, raising 25-OH-D levels by 50nmol/l could halve the hazard of a relapse. ANN NEUROL 2010;68:193-203.

Kellogg’s fortify Cereal with Vitamin D

Saturday, August 7th, 2010 | Tags: , , , , , , , ,
Posted in External News Articles, Uncategorized

Company responds to campaigning by health groups with announcement of 15% cut in sugar content in Coco Pops

cocopops2Kellogg’s has pledged to reduce high levels of sugar in its best-selling children’s cereal following a sustained campaign by health groups.

The company announced nutritional improvements to its existing Coco Pops chocolate cereal range, involving a reduction in sugar, the addition of vitamin D and the launch of a new Coco Pops Choc ‘N’ Roll cereal which will pass the Food Standards Agency’s tougher nutrient profile.

The firm said that by this time next year it would remove 15% of sugar in all its Coco Pops cereals, effectively reducing sugar content to one and a half teaspoons a serving and eliminating almost 750 tonnes of sugar from the nation’s diet annually. The sugar will be replaced with starch from grains and glucose syrup, and no artificial sweeteners will be used. Calories will be maintained at approximately 116 a serving.

The new cereal goes on sale in supermarkets tomorrow, backed by a £3m advertising and marketing campaign aimed specifically at mothers, who are predominantly in charge of the family shop.

Kellogg’s ran into controversy earlier this year after a poster advert depicting its famous cartoon monkey, Coco, dressed in school uniform under the slogan: “Ever thought of Coco Pops after school?” The company admitted it had made a mistake by showing the advert on bus shelters and other locations near schools, which meant it was seen by plenty of children. Marketing manager Peter Harrison said those locations were inappropriate.

Greg Peterson, Kellogg’s UK managing director, said: “We’ve listened to what mums have been saying and we’re responding. They want a balance: lower sugar cereals which children will still eat. We’ve invested millions of pounds … to make this happen.”

The company says it also aims to further reduce the sugar content in its Coco Pops products, provided they pass consumer taste tests.

Peterson added: “This is a process, so while we’ve announced we are taking 15% of sugar out by the middle of next year … we will go further if we can take peoples’ palates with us.”

Britons eat 29m boxes of Coco Pops a year, and 40% of UK households with children have the cereal in their kitchen cupboard.

Health and consumer groups welcomed the move, but said it was long overdue and demanded that changes be made to Kellogg’s entire product range. Jackie Schneider, of the Children’s Food Campaign, said: “We are staggered that Coco Pops currently contains 37% sugar per 100g. So this reformulation is long overdue, and it seems odd to us that the changes are being announced now, when the products won’t appear on the shelves until mid-2011 at the earliest.

“Our understanding is that the new Kellogg’s cereal would get a red traffic light, so should not be seen as an everyday food. The good news is that the nutrient profiling model which determines if food can be advertised to children certainly seems to be driving food manufacturers to reduce high levels of fat, salt and sugar. It is good to see Kellogg’s are moving in the right direction, but there is a world of breakfast foods out there that parents might prefer to these sugary cereals”

Katharine Jenner, campaign manager with the health organisation Consensus Action on Salt and Health and a nutritionist at the Wolfson Institute of Preventive Medicine, said: “Keeping children’s salt consumption low is vital. Children who eat higher salt diets are more at risk of higher blood pressure when they are adults, putting them at risk of strokes, heart attacks and heart failure. We are pleased to see Kellogg’s are responding to consumer demand and have not put so much salt into their new Coco Pops Choc ‘N’ Roll product. But all their breakfast cereals, not just this one, should be lower in salt.”

Confirmation of association between Multiple Sclerosis, CYP27B1 & Vitamin D

Confirmation of association between multiple sclerosis, CYP27B1 and vitamin D

Multiple sclerosis, MS (OMIM No. 126200), is a complex inflammatory disease that is characterized by lesions in the central nervous system.

Both genes and other environmental factors influence disease susceptibility. One of the environmental factors that has been implicated in MS and autoimmune disease, such as type 1 diabetes, is vitamin D deficiency, in which patients have lower levels of 25-hydroxyvitamin D3 (25-OHD3) in blood than do controls.

Previtamin D3 is produced in the skin, and turned into 25-OHD3 in the liver. In the kidney, skin and immune cells, 25-OHD3 is turned into bioactive 1,25(OH)2D3 by the enzyme coded by CYP27B1 (cytochrome P450 family 27 subfamily B peptide 1) on chromosome 12q13.1–3. 1,25(OH)2D3 binds to the vitamin D receptor, expressed in T cells and antigen-presenting cells.

1,25(OH)2D3 has a suppressive role in the adaptive immune system, decreasing T-cell and dendritic cell maturation, proliferation and differentiation, shifting the balance between T-helper 1 (Th1) and Th2 cells in favor of Th2 cells and increasing the suppressive function of regulatory T cells. Rs703842 in the 12q13–14 region was associated with MS in a recent study by the Australian and New Zealand Multiple Sclerosis Genetics Consortium (ANZgene).

We show associations with three SNPs in this region in our Swedish materials (2158 cases, 1759 controls) rs4646536, rs10877012 and rs10877015 (P=0.01, 0.01 and 3.5 × 10−3, respectively). We imputed rs703842 SNP and performed a joint analysis with the ANZgene results, reaching a significant association for rs703842 (P=5.1 × 10−11; odds ratio 0.83; 95% confidence interval 0.79–0.88).

Owing to its close association with 25-OHD3, our results lend further support to the role of vitamin D in MS pathology.
