title: Suboptimal long-term physical performance in children and young adults after pediatric allo-SCT.
abstract: We present a set of tests for physical performance used for annual prospective follow-up after a pediatric transplant. Of the 103 eligible patients transplanted at a mean age of 8.8 years, 94 were included. The results were divided into early, performed 1 (n=46) or 2 (n=12) years post transplant, and late tests (n=66), performed 4-16 (mean 6) years post transplant. A total of 30 patients had tests both at early and late time points (paired tests). The control subjects included 522 healthy age- and gender-matched schoolchildren. Using their test results, the s.d. score (SDS) was calculated for each patient and for each test individually. Both in the early and late tests, patients had the mean SDS for each test significantly lower (P<0.001) than controls, varying from -0.6 to -2.0 SDS. Specifically, tests measuring trunk muscles gave impaired results. In the group with paired tests, the results improved in four of six tests. In late tests, age at SCT, extensive chronic GVHD and being a sports club member correlated with the results. The potential beneficial effect of an exercise intervention program on impaired physical performance after pediatric SCT merits prospective studies.
