Juvenile dermatomyositis: medical, social and economic status in adulthood.

Eighteen adults were studied an average of 18.5 years after the diagnosis of juvenile dermatomyositis had been made. Persistent weakness was found in six patients and recurrent rash in the classic distribution in seven. Other clinical features present were Raynaud's phenomenon, arthritis and subcutaneous nodules. Minor increases in the serum creatine phosphokinase level were noted in seven patients and did not correlate with the presence of weakness or rash. Educational achievement and employment status were better in this group than in a group of adults with juvenile rheumatoid arthritis or the general adult population of British Columbia. Significant residual disability related to calcinosis and flexion contractures was present in only three of the patients.
