ABSTRACT

Polymyalgia rheumatica is an inflammatory disorder that usually affects persons over the age of 50 causing proximal muscle pain and stiffness, and an elevated erythrocyte sedimentation rate. Although increasingly recognized in this age group, it remains a diagnosis of exclusion and although several diagnostic criteria have been proposed, none has been clearly accepted. While polymyalgia rheumatica is associated with giant cell arteritis, obtaining a temporal artery biopsy is not recommended in patients with polymyalgia rheumatica without symptoms of giant cell arteritis. Early diagnosis and low dose corticosteroid therapy improve patients clinical features and functional status. Treatment usually lasts between 12 and 24 months and the majority of patients manage to discontinue treatment completely.
