Introduction: The authors present the course and manifestations of adult-onset Still's disease on the basis of five cases diagnosed at the Department of Rheumatology, Pomeranian Medical University in Szczecin.
Material and methods: The usefulness of two most popular sets of diagnostic criteria of adult-onset Still's disease (Yamaguchi and Cush) was analyzed. At onset of the disease, two out of five patients met both sets of the diagnostic criteria, two others met criteria of Yamaguchi and one of Cush. During follow-up, criteria of Yamaguchi were met in all cases.
Results: The authors suggest to use the Cushs criteria of adult-onset Still's disease when the patient does not meet the criteria of Yamaguchi and other causes of fever are excluded.
