title: [HLA-DRw typing in 40 patients with psoriasis].
abstract: 40 unrelated patients with psoriasis vulgaris were studied for their HLA-A, B and DRw antigens phenotypes. All underwent a skin biopsy to confirm diagnosis. Like most of the authors, we observed an increase in B 13 and B 17 antigens (17,50 % and 25 %) whereas in the healthy populations the percentage was (5 % and 6,02 %) respectively. The strongest increase in DRw7 suggest that the psoriasis vulgaris was associated with DRw7 antigens, with a linkage desequilibrium between the B 13 and DRw7 antigens and between the B 17 and DRw7 antigens.
