- Abstract
To assess the influence of ethnic origin on the incidence of HLA antigens in duodenal ulcer, we typed 160 white Australian patients (including 22 born in Greece or Italy) and 320 blood donor controls for the HLA-A and -B loci. 5 of the 22 (22.7%) southern European patients, but only 19 of the 138 (13.8%) of the remaining duodenal ulcer patients were found to have antigen B5 compared with 27 (8.4%) of the controls. HLA-B12 was found in 55 (34.4%) duodenal ulcer patients (including 6 of the 22 southern European patients) and 117 (36.6%) controls. No significant association of duodenal ulcer with HLA-B5 or HLA-B12 was found when differences in racial origin of patients were taken into account.
