HLA studies in chronic dermatophytosis caused by Trichophyton rubrum.

The HLA-ABC antigens were investigated in 34 and DR antigens in 28 patients with chronic dermatophytosis caused by Trichophyton rubrum. The distribution of the antigens did not differ from that of the controls. Abnormal immune response may be of importance in the susceptibility to chronic dermatophytosis, but HLA-controlled immune mechanisms seem unlikely.
