Giant cell arteritis and polymyalgia rheumatica

Giant cell arteritis and polymyalgia rheumatica are linked conditions that frequently occur in the same patient. They are more common in northern Europe and persons of European descent than in other populations. Recent investigations have begun to provide information about the pathogenesis of both syndromes. Both respond to corticosteroids but at different dose levels. Although a number of vascular complications may occur, the outlook is excellent.
