Update on polymyalgia rheumatica

Polymyalgia rheumatica is an inflammatory disease of unknown etiology affecting individuals aged fifty years and older, mainly of Caucasian ethnicity. Polymyalgia rheumatica is associated with giant cell arteritis more frequently than expected by chance alone. In both conditions, females are affected two to three times more often than males. The clinical hallmark manifestations of polymyalgia rheumatica are aching and morning stiffness in the shoulder girdle and often in the pelvic girdle and neck. Serum inflammatory markers are typically elevated, while the most consistent abnormal finding on imaging studies is bursitis in the symptomatic areas. A dramatic response to glucocorticoids is characteristic of polymyalgia rheumatica. Many patients are able to discontinue glucocorticoids six months to two years after the onset of clinical symptoms, but some patients may require longstanding glucocorticoid treatment. Glucocorticoid-sparing agents may be helpful in patients with chronic relapsing courses and those at high risk of glucocorticoid-related adverse events
