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. It has previously been shown that ASCT can induce long-term remissions in such children. The long-term effects of this treatment are still largely unknown. This retrospective study investigates the exercise tolerance and functional ability in children with JIA who have undergone ASCT compared to healthy subjects. Ten children with JIA who received ASCT between 1997 and 2003 participated in this study. Patients were tested during their regular clinical follow-up. Exercise tolerance was determined using a maximal exercise test. Functional ability was measured using the Childhood Health Assessment Questionnaire and joint status. The study group showed significantly reduced exercise tolerance compared to healthy subjects. Functional ability and joint status were also decreased in patients after ASCT. Children with JIA postASCT have impaired exercise tolerance even 9 years postASCT.
