Purpose:
To investigate the immunogenetic background of human T-cell lymphotropic virus type 1 (HTLV-1)-associated uveitis (HAU) that presents immune-mediated reactive changes in the uvea.
Methods:
HLA class I and class II genes were studied in 51 patients with HAU, 192 asymptomatic HTLV-1 carriers, and 266 HTLV-1-seronegative controls using a high-resolution method of HLA DNA typing. The HLA alleles of HAU were compared with those of HTLV-1 carriers and healthy controls.
Results:
We identified 62 distinct alleles of HLA-A, HLA-Cw, and HLA-B and 49 distinct alleles of HLA-DRB1 and HLA-DQB1 in patients with HAU, asymptomatic HTLV-1 carriers, and healthy controls. The relative frequencies of these HLA alleles did not differ among the three groups.
Conclusion:
The results suggest that HLA class I and class II genes do not contribute to susceptibility to HAU.
