Neurotoxicant exposures and rates of Chronic Multisymptom Illness and Kansas Gulf War Illness criteria in Gulf War deployed women veterans.

AIMS: This study analyzed deployment-related exposures and risk of Persian Gulf War Illness (GWI) in women veterans from the Veterans Affairs (VA) Cooperative Studies Program 585 Gulf War Era Cohort and Biorepository (GWECB CSP#585). MAIN METHODS: We examined the associations between GW deployment-related exposures and case definitions for GWI in deployed GW women. Multivariate regression analyses controlling for demographic outcomes were performed. KEY FINDINGS: Surveys were obtained from 202 GW deployed women veterans. Self-reported exposure to smoke from oil well fires as well as chemical and biological warfare were the only exposures significantly associated with the Center for Disease Control and Prevention (CDC) GWI criteria. Seventy-nine women were excluded from the rest of the analyses as they met Kansas GW illness exclusion criteria. Eligible women who self-reported deployment-related exposure to smoke from oil wells, pyridostigmine bromide (PB) pills, pesticide cream, pesticide treated uniforms, and insect baits were significantly more likely to meet the Kansas GWI criteria (n = 123) than those unexposed and exposures were related to Kansas symptom subdomain endorsements. SIGNIFICANCE: These results suggest that women GW veterans reporting deployment related exposures of pesticide, oil well fire and PB pills are significantly more likely to meet the Kansas GWI criteria in this national cohort of GW women suggesting its utility in future studies. In addition, based on these results it appears that women exposed to particular toxicants during the war may benefit from more targeted treatment strategies dependent upon the mechanism of exposure of their toxicant induced outcomes.

Prevalence and Patterns of Symptoms Among Female Veterans of the 1991 Gulf War Era: 25 Years Later.

Background: A new national cohort of Gulf War (GW) veterans of 1,318 participants was created from the Veterans Affairs Cooperative Studies Program 585 Gulf War Era Cohort and Biorepository (GWECB) pilot study. However, female veteran health outcomes have not been reported separately for those deployed versus nondeployed to the 1990-1991 GW. Methods: Using data from the cooperative studies program (CSP) #585 GWECB, this study examined whether excess prevalence and patterns of Gulf War Illness (GWI) symptoms were present among female veterans who served during the GW compared with female veterans who did not deploy to the GW (GW-Era). Results: A total of 301 women veterans participated in the survey (203 GW, 98 GW-era). Mean ages in 2016 were 53 years among GW women veterans and 54 years among GW-era women. Participant groups did not differ by age, race, ethnicity, or education, but GW women were more likely to have served in the army or navy and less likely to have served in the air force. Compared with GW-era women, GW-deployed women were significantly more likely to report 7 out of 34 symptoms related to cognitive, neurological, and mood problems and respiratory complaints when controlling for age, race, GW deployment, branch of service, and smoking status in logistic regression analyses. Ordered logistic regression was also used to estimate the association between the total number of self-reported symptoms and deployment status, age, race, branch of service, and smoking status. Results showed deployed GW veterans to have a nearly twofold risk of reporting more symptoms than GW-era women, with younger, nonwhite, army-enlisted GW women significantly more likely to report more total symptoms. Discussion: Twenty-five years after the war, GWECB women GW veterans continued to report a wide variety of symptoms at a significantly higher excess frequency prevalence than GW-era women. Our results showed at least a 14% excess frequency prevalence in all seven significantly different symptoms encompassing two out of the six Kansas GWI criteria, including neurological/mood/cognition, and respiratory domains. These results suggest that further study of these symptom domains is warranted in GW women veterans.
