title: [HL-A antigen distribution in duodenal ulcer patients].
abstract: The incidence of HLA-antigens was studied in 405 patients with clinically, roentgenologically and gastroscopically confirmed ulcer of duodenum and in 1085 controls, healthy subjects. Increased incidence of both antigens from locus B was established among the patients: HLA-B17 and HLA-BW21. A reduction of HLA-A3 incidence was found from the antigens of locus A. In the determination of incidence of HLA antigenes, depending on blood grouping ABO both of patients and healthy subjects, it was established that antigen HLA-A3 is less frequent in the patients with blood group B, whereas antigen HLA-B12 is found more often among the patients with blood group A.
