The
Last Word on Gulf War Illnesses?
On
Sunday, December 3, 2006, the Washington Post ran a front-page article on Gulf War Illnesses by
David Brown that was filled with errors. An
estimated 200,000 veterans of the first Gulf War have the condition, according
to the VA expert committee charged with making recommendations for research on
it to the Department of Veterans’ Affairs.
The
title of the article, “Funding Continues for Illness Scientists Dismiss” is
dead wrong: neither the scientific community nor the Institute of Medicine
has concluded there is no Gulf War illness. Instead, in September the
Institute of Medicine said, “Veterans of the first Gulf War report
significantly more symptoms [and more severe symptoms] of illness than soldiers
of the same period who were not deployed, [but] studies have found no cluster of
symptoms unique to Gulf War veterans.” The Institute acknowledged
that Gulf War veterans have several times the expected rates of fibromyalgia and
chronic fatigue syndrome as other veterans, as well as other symptoms.
Their illnesses are simply not unique.
This
comes as no surprise to doctors, who understand the body has only limited ways
it can respond to a huge number of insults. Lung cancer can result from
tobacco smoke or asbestos or uranium. Why should the illnesses of
Gulf veterans be unique, anyway?
Dr.
Robert Haley, head of epidemiology at the University of Texas Southwestern
Medical Center in Dallas, received a renewable 15 million dollar grant to
explore the role of nerve gas and related compounds in the illnesses of Gulf War
veterans. Haley’s research
is based on the reasonable hypothesis that exposure to organophosphates (such as
sarin) led to neurological symptoms in vets. However, Post author David Brown
said there is a “scientific consensus against” Haley. Brown further
claims, “air containing the vaporized compound drifted over troops, but there
is no evidence that anyone actually came in contact with sarin.”
Did
troops get exposed to sarin when it drifted over their heads? During
combat operations, chemical monitors went off repeatedly, signifying the
material did reach troop level. Yet studies of troops exposed to sarin at
Khamisiyah have been less than revealing. However, in 2003 the GAO
reported, “DOD’s conclusion, based on the findings of epidemiological
studies—that there was no significant difference between rates of illness for
exposed versus not exposed troops—is not valid” and “DOD and CIA plume
modeling results are not reliable.” If you can’t identify which troops
were actually exposed, it's impossible to measure the effects of an exposure.
No wonder some studies don't support Haley.
Might
low levels of sarin, or similar toxic substances that troops were exposed to
(pesticides, flea collars, nerve agent pretreatments) collectively lead to later
illness? Brown says, “evidence that low-level exposure to sarin can lead
to chronic illness is sparse,” and “there is also little evidence that
simultaneous exposure to toxins has lasting effects.” Yet Abou-Donia’s
group at Duke found that multiple low-level exposures can be extremely damaging
to animals. A 2003 paper studying combinations of pesticides used by
soldiers: malathion, DEET and permethrin, found “exposure
to real-life doses produce no overt signs of neurotoxicity but induce
significant neurobehavioural deficits and neuronal degeneration in brain.”
Did
the researchers cited by Brown actually tell him Gulf War veterans were no
sicker than their peers? Let’s review their publications.
Wessely’s
study of 4200 British Gulf War veterans (whose vaccinations were recorded,
unlike US soldiers) found, “Service in the Gulf was associated with various
health problems over and above those associated with deployment… a specific
mechanism may link vaccination against
biological warfare agents and later ill health.”
Gray
found Gulf War veterans had an increase in multi-symptom conditions, mental
health diagnoses, musculoskeletal disorders and injuries, especially those due
to vehicular accidents, suggesting neurocognitive impairment.
Feussner
was an investigator in two large treatment studies of Gulf War veterans.
How could he investigate treatments for an illness if it didn’t exist?
David
Brown has this story all wrong.
The
VA’s Research Advisory Committee on Gulf War Veterans’ Illnesses summarized
current findings on these illnesses in its 2004 report:
“A
substantial proportion of veterans of the 1990-1991 Gulf War continue to
experience chronic and often debilitating conditions characterized by persistent
headaches, cognitive problems, somatic pain, fatigue, gastrointestinal
difficulties, respiratory conditions and skin abnormalities…Research studies
conducted since the war have consistently indicated that psychiatric illness,
combat experience, or other deployment-related stressors do not explain Gulf War
veterans’ illnesses in the large majority of ill veterans…Contrary to
previous assumptions, exposure to nerve agents at levels too low to produce
acute symptoms can result in chronic adverse effects on the nervous and immune
systems.”
The
report called for long-term safety studies of anthrax vaccine, and of
combinations of exposures. Finally, the report noted that “Progress in
understanding Gulf War veterans’ illnesses has been hindered by lack of
coordination and availability of data maintained by DOD and the Department of
Veterans’ Affairs.”
We
owe it to Gulf veterans and to soldiers deployed today to get this story right.
It’s time to release the missing records, use the data they provide to
research the effects of different exposures, including vaccines, and avoid the
harmful exposures in future deployments. Finally,
identifying effective treatments for these complex, multi-symptom illnesses is
overdue.
