Research abstract
Veterans from the 1991 Gulf War (GW) have suffered from Gulf War illness (GWI) for nearly 30 years. This illness encompasses multiple body systems, including the central nervous system (CNS). Diagnosis and treatment of GWI is difficult because there has not been an objective diagnostic biomarker. Recently, we reported on a newly developed blood biomarker that discriminates GWI from GW healthy controls, and symptomatic controls with irritable bowel syndrome (IBS) and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).
The present study was designed to compare levels of these biomarkers between men and women with GWI, as well as sex-specific effects in comparison to healthy GW veterans and symptomatic controls (IBS, ME/CFS). The results showed that men and women with GWI differ in 2 of 10 plasma autoantibodies, with men showing significantly elevated levels. Men and women with GWI showed significantly different levels of autoantibodies in 8 of 10 biomarkers to neuronal and glial proteins in plasma relative to controls.
In summary, the present study addressed the utility of the use of plasma autoantibodies for CNS proteins to distinguish among both men and women veterans with GWI and other healthy and symptomatic control groups.
Excerpt
Our next analyses compared male veterans with GWI to all male controls from our prior study (healthy GW veterans, non-veterans with IBS or ME/CFS) [19]. We then performed the same analyses comparing women veterans with GWI to the combined all women control group (non-veterans with IBS and ME/CFS). The results showed that men with GWI had significantly higher levels of autoantibodies for 9 out of the 10 autoantibodies when compared with male healthy GW veterans or with the combined male control group. Women with GWI showed significantly higher values for 2 out of the 10 autoantibodies when compared with women healthy GW veterans and with 8 out of 10 autoantibodies when compared with their respective combined women control group (nonveterans with IBS and ME/CFS).
These results suggest that women with GWI appear to be showing more neuronal cytoskeletal and neuroinflammatory changes when compared to healthy GW controls or women with IBS or ME/CFS
This suggests that male GWI veterans may be showing more chronic glial activation, neuronal damage, and neuroinflammation than their male control healthy and symptomatic counterparts with IBS and ME/CFS because S100B is a marker of current BBB disruption and GFAP is a marker of current neuroinflammation [39,40]. This is because GFAP is secreted by activated astrocytes, which leads to neuroinflammation [41,42,43].
A major strength of our study is that it represents both healthy and symptomatic GW veteran groups as well as symptomatic non-veteran controls with ME/CFS or IBS. This suggests that both men and women veterans with GWI differ not only from their healthy GW veteran controls but also have more CNS differences than other groups of men and women with chronic multi-symptom illnesses. In addition, the CNS autoantibody analyses were performed with the laboratory staff blinded to the case status of all participants.

The meaning of recovery differed between participants—expectations for improvement and deployment of the sick role (and associated stigma) were key influences. While some saw recovery as complete freedom from symptoms, many defined it as freedom from the “

meets the criteria for CFS/ME. The patient and patient’s parents reported 6 months of fatigue, which was not improved even after an adequate period of sleep and very low physical performance. According to the parents, the patient has difficulty concentrating, is morose most of the day and reports limb twitching and paraesthesia.
Outpatient assessment of a patient with fatigue and chronic pain can be challenging. This is particularly the case when the patient is polysymptomatic and they have had many interactions with healthcare professionals before. It is all too easy to ‘admit defeat’ as in Dr A’s case, or initiate a test or another referral in ‘response’ to every symptom described by the patient during the course of their illness (Dr B). How can this be avoided?
Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) is a rare disease with no known etiology. It affects 0.4% of the population, 25% of which experience the severe and very severe categories; these are defined as being wheelchair-, house-, and bed-bound. Currently, the absence of biomarkers necessitates a diagnosis by exclusion, which can create stigma around the illness.
