Abstract:
Several articles have suggested that immune dysregulation related to Gulf War deployment may be involved in chronic illnesses with an unclear etiology among Gulf War veterans. To determine whether genetic susceptibility related to the human leukocyte antigen (HLA) system might play a role in development of the veterans' illnesses, we examined the frequency distribution of HLA A, B, DR, and DQ antigens from symptomatic veterans residing in south-central Pennsylvania compared with a local healthy population database. Only HLA-A28 demonstrated statistical significance. A28 was present in 7 (21.9%) of 32 of the veterans and 15 (6.9%) of 217 of the healthy population (p = 0.01, Fisher's exact test). This accounts for a minority of the ill veterans tested and is not statistically significant when corrected for the number of antigens determined. We conclude that specific HLA antigens are not strongly associated with the illnesses of Gulf War veterans.
