The frequency of 24 HLA antigens was determined in 43 patients with giant cell arteritis (25 of whom had polymyalgia rheumatica) and 12 others with polymyalgia rheumatica without evident arteritis. No haplotype was present in significantly increased frequency above controls in the total group nor when the patients were separated according to the presence or absence of polymyalgia rheumatica.

Case Reports
Polymyalgia rheumatica and temporal arteritis in blacks--clinical features and HLA typing.
Reports of polymyalgia rheumatica and temporal arteritis in blacks are rare. We analyzed five cases of polymyalgia rheumatica and one case of temporal arteritis appearing in blacks. ⋯ A previously unrecorded case of polymyalgia rheumatica and biopsy-proven temporal arteritis in a black had a similar presentation and course as cases in whites. HLA typing of five cases of polymyalgia rheumatica in blacks revealed an increased incidence of AW30 and BW16 in comparison to whites and polymyalgia.
