polymyalgia rheumatica

(pŏl″ē-mī-ăl′ j(ē-)ă) ABBR: PMR. A rheumatologic illness marked by fevers, malaise, weight loss, muscle pain, stiffness (esp. of the shoulders and pelvis), and morning stiffness. It occurs primarily, but not exclusively, in white people over 60. The cause of PMR is unknown. Although there is no single diagnostic test for PMR, patients typically have a markedly elevated erythrocyte sedimentation rate (>50 mm/hr) and no evidence of another disease (such as infection, cancer, rheumatoid arthritis, or lupus). Patients obtain rapid and durable relief from corticosteroids but usually require a course of treatment lasting 6 to 18 months. Pathologically, and sometimes clinically, PMR is related to giant cell arteritis. Mild cases may sometimes respond to nonsteroidal anti-inflammatory drugs. SYN: polymyalgia arteritica.
