IOM report urges significant commitment to treating Gulf War ‘multisymptom’ illness

“Veterans who continue to suffer from these symptoms deserve the very best that modern science and medicine can offer to speed the development of effective treatments, cures, and – we hope – prevention.”

Military service in the Persian Gulf War is a cause of post-traumatic stress disorder in some veterans and is also associated with multisymptom illness; gastrointestinal disorders such as irritable bowel syndrome; substance abuse, particularly alcoholism; and psychiatric problems such as anxiety disorder, says a new report from the Institute of Medicine,* the latest update in a series of reports on the Gulf War and veterans’ health.

There is some evidence that service during the conflict is linked to fibromyalgia and chronic widespread pain, amyotrophic lateral sclerosis, sexual difficulties, and death due to causes such as car accidents in the early years after deployment, but the data are limited, said the committee that wrote the report.

There is a pressing need to answer lingering questions, such as:

•  Why some veterans suffer a range of symptoms whereas others experience specific, isolated health problems or no ill health,

•  And why some veterans who were not on the ground during the conflict or who arrived after combat ended have multisymptom illness, while others who served on the ground during the height of the battle have experienced few or no symptoms. 

The dearth of data on veterans’ pre-deployment and immediate post-deployment health status and lack of measurement and monitoring of the various substances to which veterans may have been exposed make it difficult – and in many cases impossible – to reconstruct what happened to service members during their deployments nearly 20 years after the fact, the committee noted.

The report calls for a substantial commitment to improve identification and treatment of multisymptom illness in Gulf War veterans.

•  The path forward should include continued monitoring of Gulf War veterans and development of better medical care for those with persistent, unexplained symptoms.

•  Researchers should undertake studies comparing genetic variations and other differences in veterans experiencing multisymptom illness and asymptomatic veterans.

It is likely that multisymptom illness results from the interactions between environmental exposures and genes, and genetics may predispose some individuals to illness, the committee noted.

There are sufficient numbers of veterans to conduct meaningful comparisons given that nearly 700,000 U.S. personnel were deployed to the region and more than 250,000 of them suffer from persistant, unexplained symptoms.  A consortium involving the U.S. Department of Veterans Affairs, U.S. Department of Defense, and National Institutes of Health could coordinate this effort and contribute the necessary resources.

The committee’s review updates a 2006 IOM report that cataloged health effects occurring at higher rates among Gulf War veterans, and takes into account data and information generated since 2005.

This report takes a different approach to the issue of multisymptom illness than the 2006 study, which looked at analyses of unexplained illness and symptoms reported by veterans to determine whether they are experiencing a unique syndrome that could be defined by the symptoms.

•  The current study began with the premise that multisymptom illness is a diagnostic entity.

•  It examined the evidence to determine whether a link exists between multiple, unexplained symptoms and Gulf War deployment and, if so, how strong the association is.

The committee concluded that multisymptom illness is linked to Gulf War service, based on the availability of a number of good-quality surveys documenting increased reporting and occurrence of multiple, unexplained symptoms among veterans from several countries that sent troops, including the United Kingdom and Australia.

The data are not strong enough to draw conclusions about what chemical, drug, pollutant, or other substance could have caused these symptoms, the committee said.  Many questions remain about the underlying cause or causes of the complex of symptoms experienced by some veterans and about the adequacy of studies that have looked at the potential contributions of various substances to this disorder.  

“It is clear that a significant portion of the soldiers deployed to the Gulf War have experienced troubling constellations of symptoms that are difficult to categorize,” said committee chair
Stephen L. Hauser, MD, professor and chair, department of neurology, University of California, San Francisco:

•  “Unfortunately, symptoms that cannot be easily quantified are sometimes incorrectly dismissed as insignificant and receive inadequate attention and funding by the medical and scientific establishment.

•  “Veterans who continue to suffer from these symptoms deserve the very best that modern science and medicine can offer to speed the development of effective treatments, cures, and – we hope – prevention.

•  “Our report suggests a path forward to accomplish this goal, and we believe that through a concerted national effort and rigorous scientific input, answers can be found.”

The report was sponsored by the U.S. Department of Veterans Affairs.

    I am a Gulf War veteran who flew in and out of theater as an Air Force pilot on cargo aircraft, after the combat had ended. I suffer from FM, CFS, IBS (although much better since I cured the candida problem), migraines, and much more. I used to be a triathlete, but all that is gone now. However, I also am very proactive about my health, and I have already been tested for XMRV, but my test came back negative. I am waiting to be retested when WPI gets their new test up and running. It would be interesting to compare notes with other veterans who have been tested for XMRV, as it is possible Gulf War folks have a different cause for their problems not yet known.
