Giant Cell Arteritis in AJ Americans.
Giant cell arteritis is often considered less common in African Americans. In 1985, we reviewed 34 African American patients with biopsy-proven temporal arteritis. We report on 9 additional biopsy positive patients seen at the Washington Hospital Center (WHO between 1988 and 1996.Clinical presentations were similar to those reported in previous series, with the exception that only one patient had polymyalgia rheumatica. Two patients had visual symptoms, but only one patient had permanent monocular visual loss. In combining our 9 new patients with 41 biopsy-proven, well characterized, published patients and comparing them with a representative Caucasian group, we found statistically significant differences. Male gender, anemia, and visual loss were overall more common in African Americans, whereas constitutional symptoms and polymyalgia rheumatica were less common. The detection rate of temporal artery biopsies at WHC was lower than rates reported in other studies, but they did not differ by race.We conclude that giant cell arteritis should be pursued as a diagnosis in all patients presenting with appropriate clinical features, regardless of race, and that earlier recognition may account for the lower incidence of permanent visual loss.
