Abstract:

The aetiology of Gulf-War GW related illnesses remains unclear. The proposal has made that multiple vaccines, given under the stress of deployment with additional effects of the T helped 2 Th2 adjuvant pertuseia could skew the immune response towards a Th2 profile. The Th2 profile, characterized by the cytokines interleukin-4 IL-4 and IL-10, has been associated with symptoms such as allergic disease, hypersensitivity and depression, symptoms characteristic of which are often reported by sick GW veterans GWVs . We studied whether self-reported illness in GWVs is associated with a Th2 shift by examining Th2 IL-4, IL-10 and Thl IL-2, interferon-7 intracellular cytokine staining in helper T lymphocytes by flow cytometry after mitogenic stimulation. We studied GWVs with and without illness, as well as a group of control servicemen with similar symptoms who were either not deployed era controls or deployed to the Bosnia conflict. We find changes in cytokine profiles in servicemen reporting multi-symptom illness. Our data suggest that deployment to the Gulf and multi-symptom illness are associated with immune activation.
