Psoriatic arthritis and Reiter's disease. HLA antigens in mixed cases.
HLA antigens were determined in 25 Finnish patients with both Reiter's disease and skin lesions identical with psoriasis vulgaris. HLA B27 was found in 23 cases (92%) B13 was found in one case, Bw17 and Bw37 were not found at all. The absence of these three "psoriatic" HLA antigens in the present series indicates that the psoriasis-like skin lesions belong to the varying clinical picture of Reiter's disease and not to the HLA linked psoriasis vulgaris.
