Twenty-six HLA antigens of the A and B arteritis. Our results are summarized in loci were tested in 61 unrelated Caucasoid Table 1. Temporal arteritis appears to be patients with temporal arteritis (Horton associated with HLA-B14. Polymyalgia disease) and in 300 healthy controls. In rheumatica seems related with HLAtemporal arteritis, only one significant Bw38 and HLA-B5. These data suggest modification was observed: the HLA- that polymyalgia rheumatica and temporal B14 increase - 22.95% against 8.67% in arteritis, even if they are often associated, are t w o distinct diseases. controls ( P = 0.002 and P c = 0.05). Among our 61 patients, 50 were inMore details concerning t h e results have vestigated for t h e presence of polymyalgia been submitted to the HLA and Disease rheumatica and were separated into two register in Copenhagen (Arne Svejgaard, groups (Table I).
