[Rheumatic polymyalgia].
Polymyalgia rheumatica (PMR) is a common clinical syndrome that is characterized by pain and stiffness in neck, shoulder girdle and pelvic girdle. The aetiology is unknown. However, recent studies have documented an association with HLA antigens and infectious agents. It occurs mostly after the age of 50 years and is often accompanied by systemic features such as fever, asthenia, hyporexia and weight loss. An erythrocyte sedimentation rate (ESR) of at least 40 mm/hour has been considered diagnostic criterion. Nevertheless, a normal ESR accounted for up to 20% of cases of PMR. A dramatic and prompt response to corticosteroid treatment is characteristic. Giant cell arteritis/temporal arteritis (GCA) has been found in 0-80% of cases of PMR. Temporal biopsy could initially be deferred in patients with PMR younger than 70 years with no cranial symptoms, in which the risk of GCA is very low.
