[Two cases of adult onset of Still's disease in the elderly]

Abstract

Two cases of adult onset of Still's disease is in a 83-year-old and a 61-year-old women. Both cases complained of high fever, arthralgia, sore throat and maculae. Examinations on admission revealed leukocytosis and negative antinuclear antibody. Administration of prednisolone resulted in improvement of the clinical symptoms and laboratory data. In general, the onset of this disease is usually in early adulthood, but in these two cases the onset was at an advanced age. These results suggest that Still's disease of adult onset should be included in the differential diagnosis of fever of unknown origin, if the patient is elderly. In the treatment of the disease, proper attention to side effects of prednisolone and complications can be important.
