Study links asthma and post-traumatic stress disorder

19.11.2007
For the first time, a study has linked asthma with post-traumatic stress disorder (PTSD) among adults in the community. The study of male twins who were veterans of the Vietnam era suggests that the association between asthma and PTSD is not primarily explained by common genetic influences.

The study included 3,065 male twin pairs, who had lived together in childhood, and who had both served on active military duty during the Vietnam War. The study found that among all twins, those who suffered from the most PTSD symptoms were 2.3 times as likely to have asthma compared with those who suffered from the least PTSD symptoms.

The research was published in the first issue for November 2007 of the American Journal of Respiratory and Critical Care Medicine, published by the American Thoracic Society.

The study included both monozygotic (identical) twins, who share all the same genetic material, and dizygotic (fraternal) twins, who share only half of the same genetic material. “If there had been a strong genetic component to the link between asthma and PTSD, the results between these two types of twins would have been different, but we didn’t find substantial differences between the two,” said lead researcher Renee D. Goodwin, Ph.D., M.P.H., Assistant Professor of Epidemiology at the Mailman School of Public Health at Columbia University in New York City.

Several other studies have found a relationship between asthma and other anxiety disorders, Dr. Goodwin noted. This new research also confirmed previous findings that linked asthma with a higher risk of depression. “No one knows the reason for the association between asthma and mental disorders,” she said. “Asthma could increase the risk of anxiety disorders, or anxiety disorders might cause asthma, or there could be common risk factors for both asthma and anxiety disorders. Our study found the association between asthma and PTSD does not appear to be primarily due to a common genetic predisposition.”

The researchers found the association between asthma and PTSD existed even after they took into account factors such as cigarette smoking, obesity and socioeconomic status, all of which are associated with both anxiety disorders and asthma.

“It is conceivable that traumatic stress, which has been associated with compromised immune functioning, leads to increased vulnerability to immune-system-related diseases, including asthma,” Dr. Goodwin and colleagues wrote. “Alternatively, it may be that having asthma places adults at increased risk for PTSD as it increases the likelihood that they will be exposed to a traumatic situation because they have a life-threatening chronic medical condition.”

The findings suggest that a person with asthma who experiences a traumatic event may benefit from seeking professional help, because they could be more vulnerable to developing post-traumatic stress disorder, Dr. Goodwin said.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

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.
