title: HL-A and silicosis.
abstract: The search for a link between HL-A antigens and silicosis among 75 patients revealed no significant association. However, we did note a decrease in the frequency of B7; This change could be linked to a greater sensitivity to silicosis among persons who carry this antigen. There was also an increase of B8 among those silicotic patients with tuberculosis, although only a small number of patients were affected.
