Adult onset Still's disease (AOS) is an inflammatory disorder which associates variable articular and systemic manifestations. Despite a better knowledge of its biological and clinical particularities; the pathogeny of this disease remains unknown. The aim of this study is to analyze the epidemiological, clinical, biological and, outcome characteristics of AOS.
It is a retrospective study about 11 cases of AOS hospitalized over a 24-year-period (1982-2005) at The Rheumatology Department of Charles Nicolle's Hospital of Tunis. All patients responded to the Yamaguchi criteria.
Mean age was 35.4 years [20y-70y] with a sex-ratio of 0.57. Fever and articular involvement were the most frequent signs. Cutaneous symptoms were present in 6 patients. Three of our patients developed destructive arthritis. Renal amyloidosis, a rare complication of AOS, has been noted in one case.
AOS is an unfrequent disorder characterized by its diagnosis and treatment difficulties. Recent advances in immunotherapy may better the management of AOS.
