title: HLA DR4 and giant cell arteritis.
abstract: We reported the data of HLA-DR frequencies in a new series of 40 unrelated patients suffering from giant cells arteritis (Horton's disease). As previously reported by us, a large increase of HLA-DR4 antigen frequency is noted in patients compared with 146 healthy controls. Moreover, gathering together these 40 patients with the 48 other patients of our first published data, increase of the DR4 frequency is largely confirmed with a Pc less than 0.001.
