Vitamin D injection fails to prevent fractures in elderly people

14.11.2007
An annual injection of vitamin D does not reduce the rate of bone fractures suffered by elderly people.

The finding is the result of a four-year long study in which scientists from the MRC Epidemiology Resource Centre at the University of Southampton compared the number of bone fractures experienced by elderly people who received a vitamin D injection with those of men and women who were given a placebo. They found no change in the rate of hip, wrist or other non-vertebral fractures between the two groups.

The study is published online by the journal Rheumatology and will appear in the journal's December issue.

The clinical trial involved 9,440 men and women aged over 75 living in the Wessex region. Vitamin D deficiency is common amongst elderly people and is thought to contribute to the risk of osteoporotic fractures - bones broken as they are weakened by osteoporosis. The injection of vitamin D, or placebo, was given at the same time as people received their annual flu vaccine. The study aimed to determine whether giving a vitamin D injection to the elderly at the same time would help to protect them against osteoporotic fractures.

'Unfortunately the results suggest that giving vitamin D in the form of an injection doesn't appear to be beneficial to older people,' commented Professor Cyrus Cooper, leader of the research team, Professor of Rheumatology and Director of the MRC Epidemiology Resource Centre at Southampton.

He continued: 'This is one of the largest studies of its kind and we have demonstrated quite conclusively that an annual intramuscular injection of vitamin D, given in association with influenza vaccination, is not effective at reducing fractures caused by osteoporosis among elderly people living in southern England.

'Although encouraging findings were obtained from a smaller European study, our results suggest that a programme of vitamin D injections would not be a justifiable use of stretched health care resources. Although vitamin D insufficiency is common among older people, the most effective means of correcting this would be by combined oral daily calcium and vitamin D supplements.'

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
