Exercise tolerance in children with juvenile idiopathic arthritis after autologous SCT.

Children with juvenile idiopathic arthritis (JIA) often have significant physical impairment. A minority is unresponsive to combinations of medications, and a possible treatment of resistant JIA is intense immunosuppression followed by autologous hematopoietic SCT (ASCT). Children resistant to conventional therapy have a poor prognosis with regard to long-term outcome of joint function, exercise tolerance and quality of life.
