The subjects were 85 Japanese leprosy patients, 44 with uveitis and 41 without uveitis. Controls were 138 healthy subjects. A modified two-stage complement dependent microcytotoxicity test was used for typing HLA-A, -B, -C, -DR and -DQ antigens. The occurrence of HLA-DR2 antigen was significantly increased in patients as a whole (69.4%), and in the patients with uveitis (79.5%) as compared with the control subjects (35.5%). The association with DR2 was even stronger in the patients with uveitis (odds ratio = 7.1, Pc < 0.000005) than in the patients as a whole (odds ratio = 4.1, Pc < 0.0001). On the other hand, HLA-DR53 antigen was significantly decreased in the patients as a whole (43.5%) and in the patients with uveitis (36.4%) as compared with the control subjects (69.6%). No significant difference in the distribution of HLA antigens was observed in the patients without uveitis. Our results suggest that HLA-DR2 contributes to the susceptibility to uveitis in Japanese leprosy patients.</p>  a0029-0203
