Is there immune dysregulation in symptomatic Gulf War veterans?
Many Gulf War veterans complain of a variety of symptoms including skin rashes and joint pain which may have a common immunological basis. Other Gulf War veterans have post-traumatic stress disorder (PTSD), an anxiety disorder associated with chronic stress. Whether or not chronic stress may affect the capacity to resist disease has not been fully delineated, but recent work suggests that a dysregulated balance of cytokines produced by T helper cells of the immune system may play a role in stress-related illnesses. It is known that a balanced immune response (cell-mediated and humoral immunity) is an important defense mechanism. Although the mechanism(s) by which a change in immune system balance occurs is not clear, it may be secondary to stress-induced changes in hormones such as cortisol and catecholamines, both of which have been implicated in altering levels of cellular or humoral immunity. For these reasons, we are investigating the function of both the cellular and humoral arms of the immune system as well as the cytokine patterns associated with these different functions in symptomatic Gulf War veterans and control groups consisting of asymptomatic Gulf War veterans and symptomatic non-Gulf War veterans.
