Two senior paediatric pathologists say they have discovered vitamin D deficiency in a significant number of children who have died of Sudden Infant Death Syndrome (SIDS)- cot deaths.The two doctors, Dr Irene Scheimberg and Dr Marta Cohen, say that vitamin D deficiency and associated diseases such as the bone disease rickets could also explain deaths that are often thought to be suspicious.

Both doctors believe their findings merit further investigation and research.

The findings in children from London and Yorkshire followed the discovery by Dr Scheimberg in 2009 of congenital rickets in a four-month-old baby whose parents had been accused of shaking him to death.

Chana Al-Alas,19, and Rohan Wray, 22, were acquitted of murdering their son Jayden after the jury learned that his fractures, supposedly tell tale signs of abuse, could have been caused by his severe rickets. Dr Scheimberg also discovered rickets in Jayden’s mother.

In London, Dr Scheimberg discovered vitamin D deficiency in a further 30 cases. Vitamin D deficiency was found to be a cause of death in three cases. Cardiomyopathy, a disease of the heart muscle, was discovered in two small babies. A third died of hypocalcemic fits, a condition of low serum calcium levels in the blood caused by vitamin D deficiency.

Vitamin D deficiency was a co-existing finding in the sudden and unexpected deaths of eight children, so-called Sudden Infant Death or Sids; in five children with bronchial asthma and another five with combined bacteria-polyviral or polyviral infections. Two of the babies, including baby Jayden, also had rib fractures.

In Yorkshire, Dr Cohen found moderate to severe levels of vitamin D deficiency in 45 children, mostly infants aged less than 12 months, who died of natural causes. Of the 24 sudden infant deaths Dr Cohen investigated from this group, 18 – or 75% – were deficient in vitamin D.

Dr Scheimberg said severe vitamin D deficiency could make the bones of small babies very brittle and capable of fracture with little or no real force.

Dame Sally Davies Chief Medical Officer was quoted as “We need to investigate the vitamin D levels of these children carefully and the circumstances in which the bones fracture,” she explained.

“Obviously if you have bones that fracture easily then they will fracture easily they will fracture with any normal movement like trying to put a baby grow on a baby you will twist their arm. In a normal child you won’t produce anything. But in a child whose bones are weakened and [who have] an abnormal cartilage growth area, then it’s easier for them to get these very tiny fractures or even big fractures.”

Vitamin D is actually a hormone, and endocrinologists are experts in how the body is regulated by the hormone excreting glands – or endocrine organs.

Stephen Nussey is professor of endocrinology at St George’s Hospital at Tooting in south London. He believes that, despite repeated government recommendations on vitamin D supplementation, vitamin D deficiency is still not being taken sufficiently seriously by the authorities.

“Lizards are quite like humans in their vitamin D. Their dietary intake is pretty low and they need to have sun exposure and you need to have a light in the enclosure in which you keep your lizard of the right wavelength.

“If you don’t have one of those lights your reptile will get osteomalacia [adult rickets] very similar to humans. I guess the RSPCA would quite rightly prosecute you if you didn’t give your reptile vitamin D.

“But there’s no action taken against you if you don’t give it to your daughter. So that rather illustrates the importance placed on vitamin D for your reptile rather than giving it to your daughter.”

Earlier this week, the chief medical officer for England, Dame Sally Davies, wrote to doctors, nurses and other health professionals advising them to consider vitamin D supplementation for certain at risk groups, including pregnant mothers.

“We know a significant proportion of people in the UK probably have inadequate levels of vitamin D in their blood. People at risk of vitamin D deficiency, including pregnant women and children under five, are already advised to take daily supplements. Our experts are clear – low levels of vitamin D can increase the risk of poor bone health, including rickets in young children,” she explained.

“Many health professionals such as midwives, GPs and nurses give advice on supplements and it is crucial they continue to offer this advice as part of routine consultations and ensure disadvantaged families have access to free vitamin supplements through our Healthy Start scheme.

“It is important to raise awareness of this issue, and I will be contacting health professionals on the need to prescribe and recommend vitamin D supplements to at risk groups.

Children with low vitamin D levels are more likely to be at risk of developing Type 2 diabetes, according to a study suggesting a deficiency could help trigger the disease.Researchers found those with lower vitamin D levels were more likely to be obese and have higher degrees of insulin resistance, when the hormone becomes less effective at lowering blood sugar.

Dr Micah Olson, lead author of the study Diabetes & Metabolic Syndrome: Clinical Research & Reviews , published in the Journal of Clinical Endocrinology and Metabolism, said: “Although our study cannot prove causation, it does suggest that low vitamin D levels may play a role in the development of Type 2 diabetes.”

He added: “Future studies are needed to determine the clinical significance of lower vitamin D levels in obese children, the amount and duration of treatment necessary to replenish vitamin D levels in these children and whether treatment with vitamin D can improve primary clinical endpoints such as insulin resistance.”

The skin helps manufacture vitamin D, but only when exposed to strong sunlight. In the winter and early spring the body’s reserves can drop to low levels, particularly if a person has had insufficient exposure in the summer months.

Vitamin D can also be derived from certain foods, such as oily fish, eggs and fortified breakfast cereals.

Therefore, lack of vitamin D could simply be a sign of a generally unhealthy lifestyle: not getting out for enough exercise in the fresh air, and not eating a good diet.

Children who sit in front of the television for most of the day, snacking on fatty foods, are therefore likely to have lower vitamin D levels and be overweight as well. The two factors might not be biologically related.

Nonetheless, Dr Iain Frame, director of the charity Diabetes UK, said the study “adds to growing evidence of a link between low levels of vitamin D and an increased risk of Type 2 diabetes.”

He went on: “However, as the authors note, the exact causes of vitamin D deficiency and its role in the development of Type 2 diabetes are still unclear.

“Diabetes UK is currently funding research at the University of Glasgow to help establish if people with Type 2 diabetes might benefit from vitamin D supplementation.

“Until we know more, it is not possible to recommend vitamin D supplements to reduce the risk of Type 2 diabetes and people should not see this as an easy fix.

“Maintaining a healthy weight by keeping to a healthy diet and undertaking regular physical activity is still the best way to reduce your risk of developing Type 2 diabetes.”

All women who are trying to have a baby should take special ‘conception’ vitamin supplements after a study found fertility patients were twice as likely to get pregnant if they were taking them.The research involved women who were having treatment to boost their fertility but as there were no side effects from taking the vitamins, scientists said all women who are trying to conceive should consider them.

In the study half of women were given a multivitamin and mineral tablet to take each day and half were given folic acid, recommended by government to prevent abnormalities in the baby.

Four weeks later they then had a fertility drug treatment.

Women on the vitamins were more likely to conceive and 60 per cent were still pregnant three months later compared to 25 per cent on folic acid.

They were also likely to fall pregnant after fewer fertility treatments with three quarters conceiving on their first cycle, compared with less than one in five of those on folic acid, it was found.

The study conducted by researchers at Warwick University involving 56 women attending University College London and the Royal Free Hospital fertility units.

The women, who were mostly from an affluent background, all had healthy diets at the beginning of the study and later blood tests showed those on the multivitamin had higher levels of micronutrients than those only taking folic acid.

Lead author Dr Rina Agrawal, consultant obstetrician and gynaecologist and Associate Professor in Reproductive Medicine, said: “All women considering pregnancy should take a specifically formulated prenatal micronutrient supplement to optimise their chances of conception.”

She said it is not known what components of the vitamin tablet had the effects on pregnancy but the Pregnacare Conception product used contained a range of vitamins, minerals, antioxidants and substances linked to ovarian function and blood flow to the reproductive organs.

The findings are being published in the Reproductive BioMedicine Online journal.

Dr Allan Pacey, Senior Lecturer in Andrology at the University of Sheffield said “The influence of nutrition on our fertility is of general interest to the public and professionals, but there are relatively few studies which have examined this systematically and few which have shown direct benefits of taking supplements to enhance things.”

“Therefore, on the face of it, this study is interesting but we should acknowledge that this is a relatively small number of patients and the study would need to be repeated in a larger trial before we could be certain of the results.

“I can’t help but thinking that for most people, just general dietary advice would achieve the same effect and a good basket of fresh fruit and vegetables from the greengrocer each week would have much the same effect if their diet was poor.”

Glenys Jones, a Nutritionist at the Medical Research Council’s Human Nutrition Research said: “This is an interesting study and supports the body of evidence that diet plays an important role in supporting women’s health and their fertility.

“However this study alone cannot result in the general recommendation that all women undergoing fertility treatment should take a preconception multivitamin as it is a very small single study and further large-scale research is required to investigate if this is reproducible in a larger more diverse group of women.”

Catherine Collins, Principal Dietician, St Georges Hospital NHS Trust said: “Although the researchers claimed their diets were nutritionally adequate no robust data was provided to confirm this – a major concern for any trial making nutritional claims.

“We know that broad-spectrum supplements can correct dietary deficiencies and boost blood levels of iron, B12, folic acid and vitamin D – as was shown in this study which suggests these women had low intakes pre-conception.

“As this study was of women with conception problems there’s no evidence to suggest every woman considering pregnancy should take them.

“Similarly, n-acetyl cysteine and arginine have been shown to improve the efficacy of IVF treatments in a small number of studies, but there’s no evidence to support their use in natural conception. However, the nutritional advice for women contemplating pregnancy remains unchanged – take folic acid supplements until 12 weeks of pregnancy and if you decide on a multi-nutrient supplement for nutritional insurance make sure it’s one suitable for pregnancy, as the vitamin A content is lowered to ensure safety of the developing baby.
