HLA antigens in Graves' disease.

HLA typing of 86 patients with Graves' disease was performed for the A, B, C and D series antigens. An increased frequency of HLA-B8 (47 per cent) and Dw3 (51 per cent) compared with controls (23.7 and 21 per cent, respectively) was observed. The increase of B8 and Dw3 was almost exclusively found in a group of 48 patients with relapse of disease, whereas the frequency of B8 and Dw3 in patients without relapse did not differ significantly from that of the control group. No association with the presence of exophthalmos, thyroid antibodies, or antibodies to Yersinia enterocolitica serotype 3 could be found.
