title: [Clinical studies on 14 cases of adult-onset Still's disease].
abstract: We here report fourteen patients diagnosed as adult-onset Still's disease (AOSD) in our hospital. Seven patients were males (mean age at onset was 26.6 years), and seven were females (30.6 years). All of the cases had spiking fever ( > 39 degrees C) and joint symptoms. Hepatomegaly, splenomegaly, and lymphadenopathy were noted in 50% of the patients, respectively. Skin eruption was seen in twelve patients (85.7%). Among them, nine patients (64.3%) exhibited typical rash. Pleuritis or pericarditis was seen in one case each. Only one patient revealed neurological disorder. Abdominal pain was present in 50% of the cases. The ratio of occurrence of secondary amyloidosis was 14.3%. Four patients (28.6%) were diagnosed to have the apophyseal narrowing at the cervical spine (C2-C3). Two patients (14.3%) accompanied by Sjögren's syndrome were women over 40 years of age. The levels of soluble interleukin-2 receptor were significantly elevated in the sera obtained from seven patients with AOSD and four patients with juvenile-onset Still's disease, compared with normal controls. It seems to support the notion that immunopathologic processes via T cell activation play an important role in the pathogenesis of AOSD.
