Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are closely related disorders, particularly occurring in the elderly. Both diseases are characterized with high inflammatory activity. Except systemic symptoms, the clinical features include myalgias, pain of shoulder girdle and less frequently also of pelvic girdle. GCA is accompanied by inflammation of vessel walls that originate from the arch of the aorta. Localization of those affections obviously predicts further clinical feature. Etiopathogenesis of both diseases has not been elucidated yet. Certain HLA antigens can associate with the disease and some typical inflammatory pathways of the immune reaction have been discovered. Neuroendocrine changes associated with natural senescence of the organism may also be implicated in the pathogenesis of PMR and GCA in genetically predisposed subjects. Good therapeutical response to glucocorticoids supports the idea that cortisol concentration in the patients with PMR and GCA is lower compared with what could have been expected in the course of longstanding inflammation. The treatment with glucocorticoids is undertaken for relatively long time and the doses used in GCA are substantially higher than in PMR. Examination of the development of osteoporosis, its proper treatment and monitoring are necessary.
