Differences in pulmonary and extra-pulmonary characteristics in severely versus non-severely fatigued recipients of allogeneic hematopoietic stem cell transplantation: a cross-sectional, comparative study.

Impairments in peripheral muscle strength, QOL, exercise capacity, and depression are more prevalent among severe-fatigued recipients. Moreover, poorer QOL and corticosteroid use after HSCT are most important predictors of severe fatigue. Effects of comprehensive exercise programs and psychosocial support for severe-fatigued recipients in late post-engraftment period should be investigated.
