[Diagnosis and prognosis of polymyalgia rheumatica and giant cell arteritis].

Retrospectively the data were examined of 69 patients with polymyalgia rheumatica (PMR) and giant-cell arteritis (GCA), of whom 62 were treated with corticosteroids. The clinical and laboratory data, and the outcome of temporal artery biopsy were compared. In addition the relation between the course of the disease and survival was investigated. PMR and GCA are closely related syndromes with a multiform clinical presentation. There even is a group of patients with merely systemic symptoms, without specific signs of PMR or GCA. Concerning the course of the disease patients can be divided into groups with a shorter and longer period of disease activity; patients with a smooth stable remission and a chronic disease. The former group shows a significantly better five-year survival. At the time of diagnosis no reliable prediction of the course of the disease is possible.
