Federal Activities Related to the Health of Persian Gulf Veterans

DEPARTMENT OF VETERANS AFFAIRS


I. Research

The Department of Veterans Affairs (VA) research efforts examining the health of Persian Gulf veterans include epidemiological studies, and intramural and cooperative research. Specific efforts are listed below:

A. Epidemiology

Mortality Follow-up Study of Persian Gulf Veterans

Action: VA Environmental Epidemiology Service (EES).

Purpose: Because of recurring and persistent questions about the mortality experience of Persian Gulf veterans, a mortality follow-up study is planned. The mortality experience of all 697,000 Persian Gulf veterans on the Defense Manpower Data Center (DMDC) file will be compared to a matched sample of Gulf-era veterans who did not serve in the Gulf. Cause-specific mortality for both veterans groups also will be compared to the number of deaths expected in the U.S. civilian population.

Status: Ongoing. Vital status determinations and death record gathering efforts have been initiated.

Results: Not available at this time.

Coordination: VA and DoD.


Random Survey of Persian Gulf Veterans

Action: VA Environmental Epidemiology Service (EES).

Purpose: A random survey of 15,000 Reserve/National Guard veterans and active duty personnel who served in the Persian Gulf is being planned by the VA in collaboration with DoD and HHS. This mail/telephone survey will be designed to determine the prevalence of symptomatology experienced by veterans after their service in the Gulf war, and the current health status of veterans and their family members. This Gulf war cohort will be compared to a matched group of 15,000 veterans and military members who served in the same era but who were not deployed to the Persian Gulf. A second representative sample of eligible respondents will be invited to undergo a physical examination to clinically evaluate reported symptomatology.

Status: Ongoing.

Results: Not available at this time.

Coordination: VA, DoD, and HHS.


Use of Roster of Veterans Who Served in Persian Gulf Area

Action: VA, Environmental Epidemiology Service (EES), and Defense Manpower Data Center (DMDC).

Purpose: To properly address the issue of possible exposure to environmental hazards, all individuals who served in the Gulf region need to be identified. To this end, the Defense Manpower Data Center (DMDC) has prepared a computer file of over 697,000 troops assigned to the Persian Gulf area during Operation Desert Shield/Desert Storm. This database has been made available to VA's Environmental Epidemiology Service, giving VA access to demographic data on all troops stationed in the Persian Gulf.

Status: Ongoing. The data file has been used by EES in its reviews of the Persian Gulf Veterans Health Registry and the VA Patient Treatment File, and for the planning of a mortality follow-up study of Persian Gulf veterans.

Results: Not available at this time.

Coordination: VA and DoD.


B. Environmental Hazards Research Centers

In support of research on the health consequences of exposure to environmental hazards during the Persian Gulf War, VA has established three hospital-based research centers to study military and civilian exposure to environmental and occupational hazards, including psychological stress. The three centers, which were chosen in August 1994 and funded beginning October, 1994, are located at: 1) VA Medical Center East Orange, NJ, 2) VA Medical Center Portland, OR, and 3) VA Medical Center Boston, MA.

Boston VAMC Environmental Hazards Research Center

Action: VAMC Boston, MA

Purpose: The Boston Environmental Hazards Research Center, in conjunction with Boston University, is conducting six Persian Gulf-related research projects aimed at determining health effects of environmental exposure to potential hazardous agents, with a particular emphasis on behavioral toxicology, immunotoxicology, cancer epidemiology, and behavioral psychopathology. This interdisciplinary work will extend current Persian Gulf-related research at the Boston VA Medical Center that includes assessment of health, psychological well-being, and neuropsychological function. Data shared among projects will allow investigators to examine such hypotheses as whether performance on psychological tests can be related to immune function, and the relation between pulmonary test results and health symptom complaints. One project will examine the possible relationship between the experience of multiple symptom-based health complaints and such clinical phenomena as chemical sensitivities, chronic fatigue syndrome, organic brain syndromes resulting from toxicant exposures, post-traumatic stress disorder (PTSD), and somatization disorders. Other studies will investigate the central and peripheral nervous system in a group of veterans with possible environmentally related disorders, while another will assess pulmonary and immune system function in the same study cohort. Additional approaches at the Boston Environmental Hazards Research Center will seek validation of neurobehavioral tests, a rodent study of immunologic changes thought to be related to petroleum products, a registry of cancer incidence among Persian Gulf veterans, and a study of cellular receptors as a susceptibility biomarker for polycyclic aromatic hydrocarbon (a component of incomplete petroleum combustion) exposure.

Status: Ongoing.

Results: Not available at this time.

Coordination: VA, DoD, and HHS.


East Orange, NJ, VAMC Environmental Hazards Research Center

Action: VAMC East Orange, NJ

Purpose: The New Jersey Environmental Hazards Research Center at the East Orange VA Medical Center, in conjunction with the UMDNJ - New Jersey Medical School, is undertaking four projects to gather information about illnesses among Gulf veterans for development of the most characteristic symptom profiles. An epidemiological study will compare two groups of Gulf veterans to collect and organize symptoms to define illness and identify risk factors through the case-control method. Study subjects will be divided into three groups based on symptom presentation-- chronic fatigue, chemical sensitivity, and asymptomatic -- to participate in a series of studies in such areas as viral, immunological, neuropsychological and autonomic neural function. One project will examine chemical sensitivity through physiologic and cognitive reactivity to chemical challenges. Those fulfilling chronic fatigue criteria will be tested to determine physiologic and cognitive reactivity to exercise. An animal study will evaluate psychosomatic interactions with chemical exposure and pyridostigmine bromide.

Status: Ongoing.

Results: Not available at this time.

Coordination: VA, DoD, and HHS.


Portland, OR, VAMC Environmental Hazards Research Center

Action: VAMC Portland, OR

Purpose: The Portland, OR, VA Medical Center, in conjunction with Oregon Health Sciences University's Center for Research on Occupational and Environmental Toxicology, is sponsoring an environmental hazards research center to examine, in four projects, health effects associated with exposure to selected environmental chemical hazards and biological hazards related to military service. The center will identify exposures through intensive interviews and study risk factors for unexplained illnesses through a case-control epidemiological study. The center also will screen veterans for medical, chemical, and biological markers of exposure and disease, and act as a repository for data collection and analysis. Scientists from the VA medical center and university research center will work together to explore, at the whole organ and at the molecular level, key scientific issues involving epidemiology, neurobehavior, neuroendocrinology, neurotoxicology, dermatology and parasitology. Researchers hope to define more accurately relationships between illnesses in Gulf veterans and post-traumatic stress disorder, or specific environmental, infectious and warfare chemical exposures. Researchers plan to estimate future risks of developing symptoms in the population of exposed veterans and to begin devising appropriate treatments and intervention.

Status: Ongoing.

Results: Not available at this time.

Coordination: VA, DoD, and HHS.

II. Clinical Evaluations

The following activities are evaluations and should not be considered research. The findings of these evaluation programs cannot be used to derive specific conclusions about a causal relationship between military service during Operation Desert Shield/Storm and any potential health problems. However, these clinical evaluation programs are important in the development of hypotheses that can be tested using rigorous epidemiological, clinical, and basic science approaches.


Health Surveillance of Persian Gulf Veterans - Persian Gulf War Veterans Health Registry

Action: VA Environmental Epidemiology Service (EES).

Purpose: In response to Public Law 102-585, VA has constructed a Registry computerized database derived from diagnostic examinations and interviews administered to Persian Gulf veterans at VA Medical Centers (VAMCs) and out-patient Clinics. The Registry provides concerned veterans medical evaluations and medical care. This registry (which includes over 39,000 veterans as of December 1994) provides VA the opportunity to identify the types of health problems reported by this self-selected group of veterans.

Status: Ongoing. A uniform, comprehensive case-assessment protocol has been developed by VA and coordinated with DoD to evaluate individuals with unexplained illnesses after Persian Gulf service. The initial step toward diagnosis of medical problems possibly related to Gulf service remains the Phase 1, Persian Gulf Registry examination. For those individuals whose health problems require further evaluation, this protocol provides a comprehensive consultative/diagnostic examination.

Results: Registry results updated every three months.

Coordination: VA, DoD, and HHS.


Pilot Clinical Program to Evaluate Medical and Psychological Effects of Exposure to Environmental Hazards

Action: VAMC Birmingham, AL

Purpose: To evaluate medical and psychological effects of exposure to environmental hazards. Results of examinations provided to veterans on VA's Persian Gulf Registry are reviewed to determine if these individuals should be called back for further testing. Veterans with possible exposure to environmental hazards are screened and evaluated with a comprehensive battery of neuropsychological tests.

Status: Ongoing. Over 400 veterans have been screened for symptoms related to possible environmental exposures, and 60 veterans have completed a comprehensive, standardized, neuropsychological evaluation protocol.

Results: Not available at this time.

Coordination: VA, DoD and HHS.


Health Surveillance of Persian Gulf Veterans - Patient Treatment File (PTF)

Action: VA Environmental Epidemiology Service (EES).

Purpose: As a part of the on-going health surveillance of Persian Gulf veterans, VA inpatient medical information on Gulf veterans is closely monitored and reviewed in comparison to Gulf-era veterans.

Status: Ongoing. Review of primary discharge diagnoses currently is ongoing.

Results: Not available at this time.

Coordination: VA, DoD, and HHS.


Children of Persian Gulf Veterans in Mississippi

Action: VAMC Jackson, MS, Mississippi State Department of Health, and Centers for Disease Control and Prevention (CDC).

Purpose: Examination of children born to Persian Gulf veterans from four National Guard units and detachments for evidence of possible health effects related to their parents' service. In cooperation with the CDC and the Mississippi State Department of Public Health, the VAMC in Jackson, MS, requested the medical records of 55 children born to Persian Gulf Veterans for clinical review.

Status: Complete.

Results: Final report released December 1994.

Coordination: VA, HHS, and DoD.
