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.

Multiple sclerosis and vitamin D: a review and recommendations.

A relationship between vitamin D and several diseases, including multiple sclerosis (MS), has recently received interest in the scientific community. Vitamin D appears to have important actions beyond endocrine function, particularly for the immune system. Risk of development of MS, as well as disease severity, has been associated with vitamin D in a variety of studies. There remains a need for prospective studies to further establish this relationship. Given the current evidence of the potential benefits of vitamin D, it appears to be reasonable and safe to consider vitamin D supplementation at dosing adequate to achieve normal levels in patients with MS and clinically isolated syndrome.

Scottish Vitamin D Summit Captures International Attention

For immediate release : July 21st 2010

Shine on Scotland campaigners and the MS Society Scotland held productive talks with the Scottish Government yesterday as planning continues for the Scottish Summit on Vitamin D and MS which will take place in Glasgow in September.

Cabinet Secretary for Health and Wellbeing Nicola Sturgeon will open the event at which international researchers and scientists will be present to discuss the latest research on vitamin D and the implications for public health policy in Scotland.

In recent weeks more researchers from as far afield as Australia have confirmed their attendance at the summit.  International media organisations have also expressed an interest in the event which looks set to be high profile.

Looking ahead to September, Ryan McLaughlin said:

“It’s incredibly exciting that it’s now so close.  A lot of work has gone into the campaign and hopefully this summit will make a real difference.  The Scottish Government and Parliament have been very supportive of the campaign and it’s great to have reached this stage”.

Craig Wilkie, Head of Policy and Communications at MS Society Scotland also attended the meeting at St Andrews House:

“The Summit is a great opportunity to bring internationally renowned researchers to Scotland to discuss a hugely important public health issue.  The focus will be a practical one in terms of public health policy and we have the chance to learn lessons from other countries and make a significant contribution to the health of the nation”.

Vitamin D and Parkinson’s

Sunday, July 18th, 2010 | Tags: , , , ,

“Low vitamin D levels may increase a person’s risk of developing Parkinson’s disease,” BBC News has reported. Its website said that people with the lowest levels of vitamin D had a three-fold higher risk of developing Parkinson’s disease.

The news is based on research that followed over 3,000 Finnish people aged 50 to 79 years over a period of 29 years. Scientists took a measurement of the participants’ blood vitamin D levels and looked at how the subsequent risk of developing Parkinson’s disease over the period related to their blood vitamin D levels.

This high-quality, preliminary study showed an increased risk of developing Parkinson’s disease in those patients with the lowest vitamin D levels compared to the highest. However, Finland is a northern latitude country and so all the participants had relatively low levels of vitamin D, which the body produces using sunlight. Further research is needed to follow up whether this association is found in larger cohorts of people from different latitudes, who may have higher vitamin D levels than in this study.

Where did the story come from?

The study was carried out by researchers from the national Institute for Health and Welfare in Finland and was funded by the US National Institutes of Health. The study was published in the peer-reviewed medical journal Archives of Neurology.

This study was covered accurately by BBC News, which pointed out that it is still uncertain if there is a level of vitamin D that is optimal for brain health or a point where vitamin D becomes toxic for humans.

What kind of research was this?

This was a cohort study that looked at whether vitamin D levels in the blood earlier in life are associated with developing Parkinson’s disease later in life.

The researchers suggest that patients with Parkinson’s disease have been found to have lower vitamin D in cross-sectional studies. Problematically, cross-sectional studies, which only look at participants at one point in time, can only tell us about the vitamin D levels found in patients had already developed the disease.

To explore the possible relationship, the researchers wanted to see whether the vitamin D levels predicted Parkinson’s disease several decades later. This research looked at incidence in a population who had been followed for 29 years on average, and who were from northern latitudes (Finland) where exposure to the sun is limited and therefore the vitamin D they derived from the sun was usually low.

What did the research involve?

The researchers used data from the Mini-Finland Health Survey, which was carried out from 1978 to 1980 across 40 areas of Finland. They used data from 3,173 individuals who were free from Parkinson’s disease and psychotic disorders and who were aged between 50 and 79 years at the time of the survey.

The questionnaire contained data on socioeconomic background, medical history and lifestyle as well as baseline examination measurements of height, weight, blood pressure, cholesterol and vitamin D levels in the blood.

Cases of Parkinson’s disease were diagnosed and verified by two separate clinicians; a standard practice in the Finnish health system. Finnish patients with Parkinson’s disease can receive free medication after applying with a certificate issued by their treating neurologist. These certificates contain the symptom history and clinical findings in the patients. A neurologist from a social insurance institution then has to agree with the diagnosis described on the certificate for medication costs to be reimbursed.

Patients were followed up for an average of 29 years from their baseline examination until their diagnosis of Parkinson’s disease or death from other causes. During this period 50 members of the cohort developed Parkinson’s disease.

The researchers used an established statistical technique called the ‘Cox proportional hazards model’ to estimate the strength of association (relative risk) between vitamin D levels and the risk of developing Parkinson’s disease.

What were the basic results?

The researchers found that vitamin D concentration was lower among people with Parkinson’s disease but it was also associated with age, sex, marital status, leisure time, physical activity, smoking, alcohol consumption, BMI, diabetes, high blood pressure, blood cholesterol levels and the season in which the measurement was taken.

After adjusting for these confounding factors the researchers found that individuals with higher vitamin D levels had a lower risk of Parkinson’s disease compared to individuals with low vitamin D. The relative risk of developing Parkinson’s disease was 67% lower for the quarter of patients with the highest vitamin D levels, compared to the quarter of patients with the lowest vitamin D.

The researchers suggest that an optimal blood vitamin D concentration is 75-80 nmol/l. People in:

  • the lowest quartile had vitamin D concentrations of 8 to 28 nmol/l (men), 7 to 25 nmol/l (women).
  • the highest quartile had vitamin D concentrations in the range 57 to 159 nmol/l (men), 50 to 151 nmol/l (women).

How did the researchers interpret the results?

The researchers say that a low serum vitamin D level predicts an elevated risk of Parkinson’s disease incidence. They say that although the study population as a whole had low vitamin D levels, a dose-response relationship was found; in other words, the lower the vitamin D level the higher the chance of Parkinson’s disease.

The study did not look at mechanisms underlying the association but the researchers suggest that vitamin D could act as an antioxidant, regulate neuron activity or act through detoxification mechanisms. They also say that an enzyme that makes the active form of vitamin D is found in high concentrations in the substantia nigra, the region of the brain that is affected most by Parkinson’s disease.

An editorial accompanying this research article says that some epidemiological studies have shown a latitudinal north-south gradient for Parkinson’s disease, similar to that seen for multiple sclerosis. However, it cautions that the evidence does not seen to be as strong for Parkinson’s as it is for multiple sclerosis (MS) because other studies have not confirmed the potential link.

The authors say the research study “provides the first promising human data to suggest that inadequate vitamin D status is associated with the risk of developing Parkinson’s disease”. They add that further work is needed in both basic and clinical arenas to understand the exact role, mechanisms, and optimum concentration of vitamin D in Parkinson’s disease.

Conclusion

This was a well-conducted study that looked prospectively at the role of vitamin D in the risk of developing Parkinson’s disease, although there are some limitations to the study that the researchers highlight:

  • There were a small number of cases of Parkinson’s disease within this cohort. The researchers suggest this may have affected the accuracy of their estimates of risk.
  • The study only took a single measurement of vitamin D, which may not reflect typical variations in concentrations across the seasons and across the lifetime of each individual.
  • The blood samples had been stored for a relatively long time so the possibility that the vitamin D levels changed with storage cannot be excluded.
  • The study did not address whether there is a critical time in life that suboptimal vitamin D levels affect the risk of Parkinson’s disease.
  • The study did not include information on dietary intake of vitamin D from vitamin D rich foods such as oily fish. Such foods may contain other nutrients that may be beneficial against Parkinson’s disease.
  • The risk factors for Parkinson’s disease are not well known and therefore not all possible influencing factors may have been taken into account in the analysis.

This relatively small, preliminary study was of good quality but the researchers say that larger follow-up cohort studies are needed. Clinical trials focusing on the effect of vitamin D supplements on the incidence of Parkinson’s disease also merit follow up, they say.

It is worth noting that as this study was conducted in people who all had low levels of vitamin D. It is not known, from this study, if there is a level of vitamin D above which there is no further reduction in the risk of Parkinson’s disease. This is important as excessive amounts of vitamin D taken as supplementation in people with normal levels can cause toxicity.

More than half the world’s population gets insufficient vitamin D, says UCR biochemist

RIVERSIDE, Calif. – Vitamin D surfaces as a news topic every few months. How much daily vitamin D should a person get? Is it possible to have too much of it? Is exposure to the sun, which is the body’s natural way of producing vitamin D, the best option? Or do supplements suffice?

In the July 2010 issue of Endocrine Today, a monthly newspaper published by SLACK, Inc., to disseminate information about diabetes and endocrine disorders, Anthony Norman, a distinguished professor emeritus of biochemistry and biomedical sciences and an international expert on vitamin D, notes that half the people in North America and Western Europe get insufficient amounts of vitamin D.

Anthony Norman is a distinguished professor of biochemistry and biomedical sciences (emeritus) at UC Riverside, and an international expert on vitamin D.

Anthony Norman is a distinguished professor of biochemistry and biomedical sciences (emeritus) at UC Riverside, and an international expert on vitamin D.

“Elsewhere, it is worse,” he says, “given that two-thirds of the people are vitamin D-insufficient or deficient. It is clear that merely eating vitamin D-rich foods is not adequate to solve the problem for most adults.”

Currently, the recommended daily intake of vitamin D is 200 international units (IU) for people up to 50 years old; 400 IU for people 51 to 70 years old; and 600 IU for people over 70 years old.

“There is a wide consensus among scientists that the relative daily intake of vitamin D should be increased to 2,000 to 4,000 IU for most adults,” Norman says. “A 2000 IU daily intake can be achieved by a combination of sunshine, food, supplements, and possibly even limited tanning exposure.”

While there is now abundant data on vitamin D and its benefits, Norman believes there is room for more study.

“The benefits of more research on the topic justifies why this field of research deserves additional governmental funding,” he says. “Already, several studies have reported substantial reductions in incidence of breast cancer, colon cancer and type 1 diabetes in association with adequate intake of vitamin D, the positive effect generally occurring within five years of initiation of adequate vitamin D intake.”

Because vitamin D is found in very few foods naturally (e.g. fish, eggs and cod liver oil) other foods such as milk, orange juice, some yogurts and some breakfast foods are fortified with it. The fortification levels aim at about 400 IU per day.

Norman, who holds the title of Presidential Chair in Biochemistry-Emeritus, has been researching vitamin D for nearly 50 years. In 1967, his laboratory discovered that the vitamin is converted into a steroid hormone by the body. Two years later, his laboratory discovered the vitamin D receptor (or VDR), an essential receptor for the steroid hormone form of vitamin D that is present in more than 37 target organs of the body that respond biologically to the vitamin.

“There is now irrevocable evidence that receptors in the immune, pancreas, heart-cardiovascular, muscle and brain systems in the body generate biological responses to the steroid hormone form of vitamin D,” he says.


Oliver Gillie: Time to abandon this outdated view on staying out of the sun

Lack of sunshine and the vitamin that it makes in our skin is probably the most serious single cause of disease in the UK today.

Vitamin D deficiency is well known as the classic cause of rickets and serious bone diseases, but in the last 10 years it has also been identified as a major risk factor for diabetes, heart disease, arthritis, infections, some cancers and other ills.

The cost of all this disease to the UK has been put at an astounding £27bn annually, which compares with only £5bn for the cost of disease caused by smoking.

Small amounts of vitamin D can be obtained from food but you can’t obtain more than about 10 per cent of the optimal amount this way unless you eat oily fish – skin and all – three times a day.

We depend on the sun for our vitamin D. Since our weather is so unreliable, British people suffer more than almost any other from vitamin D deficiency.

Many years of bad advice has also been a factor.

The British Isles are located far north so the winter sun is not strong enough to make any vitamin D. The prevailing westerly wind bringing cloud in from the Atlantic is also against us. The Scots are worst off because there is nothing to the west to protect them. Their vitamin D levels are lower and they have the highest incidence of multiple sclerosis in the world.

Scientists studying MS now believe that it may be prevented if women take vitamin D in pregnancy and children take regular supplements. Another devastating disease, diabetes type 1 – affecting mostly children who must inject themselves with insulin – could be prevented by the same vitamin D supplements.

Indeed it is possible that these two diseases could now be eradicated if Government had the will.

However a recommendation that pregnant women take vitamin D has been ignored over many years by obstetricians.

Standard advice is that babies are not given vitamin D until they are six months old. Nobody any longer remembers the reason for this, which is implemented nowhere else.

Everybody thinks that breast milk is a complete food – and so it might be if mothers sunbathed as often as they can. As it is, breast milk in the UK is deficient in vitamin D while artificial milk is supplemented.

This need not be a problem if mothers give vitamin D drops to their babies. Melanoma, the worst form of skin cancer, has dramatically increased during some 20 years of advice to avoid the sun and use suncream. This is quite possibly because the advice has been wrong. Suncream blocks the action of UVB (shortwave ultraviolet radiation from the sun) – so blocking synthesis of vitamin D with loss of protection against cancer – while UVA (longwave radiation), which seems to carry the main risk of melanoma, is not blocked by many creams.

We could do much, much more. The Irish Republic has already fortified semi-skimmed milk with vitamin D, Finland has fortified milk and Israel is making milk fortification mandatory. Jordan is bringing in fortification of bread.

The UK the Food Standards Agency has hummed and hawed. The United States has had fortification for 80 years. What are the English and Scots waiting for?

The one simple action open to us all is to sunbathe, carefully without burning. The sun is natural, free, and safe if you are sensible. It’s also good to take a vitamin D supplement of at least 1000 to 2000 IUs [international units of measurement] per day.

Pregnant women ‘must take vitamin D supplements’

Sunday, July 4th, 2010 | Tags: , , , , , ,

_48240754_vitamins

By Caroline Parkinson
Health reporter, BBC News

Pregnant women in the UK should be told to routinely take vitamin D supplements, researchers say.

The team at University College London Institute of Child Health says official bodies currently offer conflicting advice.

Writing in the British Journal of Nutrition, they say there is a “strong case” for a daily dose of vitamin D in pregnancy.

But one leading expert said more evidence was needed.

The Department of Health advises pregnant women to ensure they receive a certain level of vitamin D – 10 micrograms per day. The researchers say this in effect endorses use of supplements, because diet and the sun provide too little.

But the National Institute of health and Clinical Excellence (NICE) said in its guidance that it did not support supplements.

It has instead said that women should simply “be informed” about the importance of having adequate vitamin D levels during their pregnancy and while breastfeeding – adding that some women may choose to do this via supplements.

Additionally, pregnant women on low incomes are entitled to a range of nutrients – including vitamin D – as part of the Healthy Start Scheme.

‘Unacceptably high’

The paper said the UK was the only one of 31 countries examined which did not recommend that women of reproductive age took a vitamin D supplement, and that it also fails to endorse a daily supplement for expectant mothers.

Dr Elina Hypponen, co-author of the paper, said: “The incidence of vitamin D deficiency in pregnant women in Britain is unacceptably high, especially during winter and spring.

“This is compounded by a lack of exposure to sunlight and the limitations of an average diet to meet the optimal need.

“In the most severe cases, maternal vitamin D deficiency can be life threatening to a newborn.

“We believe that the routine provision of a daily supplement throughout pregnancy would significantly decrease the number of mothers who are clearly vitamin D deficient, reducing related serious risks to their babies.”

Dr Hypponen said past evidence showed a proactive approach to supplements coincided with a much lower incidence of deficiency linked diseases such as infantile hypocalcaemia [also known as William's syndrome, which affects development], and rickets [which weakens bones].

One in four

The authors say women from some ethnic minorities are recognised to be at greater risk because their darker skin means they do not absorb as much sunlight.

But they add that the problem is also common among white women, even when they live in southern England.

Women are more likely to be vitamin D deficient than men, and a previous study found one in four pregnant mothers has been found to be vitamin D deficient during winter and spring

The Royal College of Obstetricians and Gynaecologists recommends only women at risk of vitamin D deficiency should take a supplement.

Patrick O’Brien, a spokesman for the college, said: “There is gradually accumulating evidence that universal vitamin D supplementation in the UK might be beneficial for the whole population.

“But more research is needed on the balance of risks and benefits in women at low risk of vitamin D deficiency, and on the correct dosage to use.”

MS campaigner concerned on safe sun advice

Posted in Uncategorized

Ryan McLaughlin from the Shine on Scotland campaign is growing concerned about the mixed bag of advice given on sun exposure and the message being given to parents on a childs ’safe sun exposure’ by groups who are giving poor advice to parents and advising parents to ‘ lotion children up before going out ‘

In a recent message Ryan heard on the radio the message advised all parents to cover children totally up and to put on sunscreen some 20 mins before going outdoors and to adopt it as common routine –  it was then backed up by a Politician.

Now 15 yr old campaigner will work gain a general consensus from all groups concerned to issue a common ’safe sun message’ across the UK over the coming months that looks after children’s health.

Statement by Ryan Mclaughlin:

” All children need  a little sun exposure to get essential vitamin D and need to get our levels built up – even in summer months , vitamin D deficency is a major health issue across the UK and Vitamin D is needed for our future health, we simply cant ignore this problem any longer ”

Worried parents no longer know what to do and what is safe and what is not.

“The current advice being given on ’safe sun exposure’ is being exploited, parents are being told constantly by influential groups to cover children up with sunscreen and so children are robbed of essential sun exposure and vitamin D.

Children are not supposed to live in the dark so to speak and a little sun exposure is very good for us, we children need some sunlight we cant grow properly without it .

The current advice being given out is extremely worrying and the message to parents is being exploited by the sunscreen industry.

Ryan confirms new PM has received his message

Ryan Mclaughlin confirms Prime Minister David Cameron has received his message.

Ryan Mclaughlin would like to confirm that he has received a personal letter from the UK Prime Minister and has since written back urging him for a meeting to discuss an immediate action plan for the future of each and every childs health in the UK.

15 yr old Ryan Mclaughlin has personally written to the PM in response to the letters received from the campaigners numerous calls for national action to be taken by the NHS to tackle vitamin D deficiency across the UK and the financial impact on our NHS and the savings that it could bring.

A recent scientific review said that a European wide supplementation program of vitamin D such as Ryan has already proposed in Scotland could save Europe £165 billion a year , schoolboy Ryan Mclaughlin pleads with our UK politicians to do it quickly for our children health and not for just financial reasons.

Pregnant mothers should be given vitamin D to help safeguard babies’ health

Researchers at the UCL Institute of Child Health (ICH) are calling for the swift reintroduction of vitamin D supplements to pregnant women in the UK.

In an article published online today by the British Journal of Nutrition (BJN), the authors argue that despite a growing body of evidence that links vitamin D deficiency to complications in pregnancy and poor neonatal health, the UK remains the only one of 31 European countries that doesn’t have a set vitamin D recommendation for women of reproductive age, whilst also failing to endorse a daily supplement to expectant mothers.
Dr Elina Hyppönen, reader in epidemiology and public health at the ICH and a co-author explains, “The incidence of vitamin D deficiency in pregnant women in Britain is unacceptably high, especially during winter and spring.  This is compounded by a lack of exposure to sunlight and the limitations of an average diet to meet the optimal need.

“In the most severe cases, maternal vitamin D deficiency can be life threatening to a newborn. We believe that the routine provision of a daily supplement throughout pregnancy would significantly decrease the number of mothers who are clearly vitamin D deficient, reducing related serious risks to their babies.

“Our take on vitamin D supplementation in the UK has seen many changes over the decades and we can see clearly from past experience that a proactive approach to supplementation has coincided with a much lower incidence of deficiency linked diseases such as infantile hypocalcaemia and rickets.”
Current data for the UK shows that women are more likely to be vitamin D deficient than men (9.2 and 6.6 per cent respectively). Pregnancy poses a particularly high risk situation, with one in four pregnant mothers being vitamin D deficient ( below 25nmol/l) during winter and spring, with nearly all (90 per cent) having concentrations considered insufficient (below 50nmol/l).
In the article, Dr Hyppönen and her co-author, Barbara J Boucher (Queen Mary, University of London) draw on historical data that supports the case for a daily dose of at least 10µg of vitamin D to prevent vitamin D deficiency in pregnant mothers, and recent evidence suggesting potentially wide-ranging benefits for the prevention of deficiency for the health of the mother and her child.
“This risk of vitamin D deficiency is largely being overlooked by our health professionals. Under a current government scheme, pregnant women who are on a low income are entitled to receive supplements free of charge, but there is no strong evidence to suggest that this group are at greater risk.
“What’s needed is a unified approach that will ensure that all expectant mothers, regardless of their economic status, are informed of the benefits of taking a regular supplement throughout pregnancy.”
