Impairments in dyspnea, exercise capacity, physical activity and quality of life of allogeneic hematopoietic stem cell transplantation survivors compared with healthy individuals: a cross sectional study.

: A limited number of studies have reported impairments in physical activity, exercise capacity and quality of life (QOL) in allogeneic hematopoietic stem cell transplantation (allogeneic-HSCT) recipients. We aimed to compare dyspnea, exercise capacity, physical activity and QOL in allogeneic-HSCT recipients with age-gender matched healthy individuals, since this has not been investigated hitherto. : A total of 80 allogeneic-HSCT recipients (>100 days status post-transplantation) (38.88 ± 13.25 years) and 60 healthy individuals (35.92 ± 10.83 years) were compared. Exercise capacity [6-minute walk test (6-MWT)], physical activity level (total and active energy expenditure, moderate and severe physical activity duration, number of steps, average metabolic equivalent, lying down and sleeping duration) [metabolic holter], QOL [European Organization for Research and Treatment of Cancer QOL Questionnaire (EORTCQOL)], dyspnea [Modified Medical Research Council Dyspnea scale] and pulmonary functions [spirometry] were evaluated. Clinical trials #NCT03606005. : Six-MWT distance, energy expenditure, physical activity duration, number of steps, average metabolic equivalent, global health status, functional and social function subscales of EORTCQOL were significantly lower in recipients compared with controls; dyspnea score, lying down, sleep durations, symptom and fatigue subscales of EORTCQOL were significantly higher in recipients compared with controls ( < 0.05). : Dyspnea during daily living activities, exercise capacity, physical activity level and QOL are considerably impaired in allogeneic-HSCT recipients during post-engraftment period. To improve impaired outcomes, allogeneic-HSCT recipients should be oriented to cardiopulmonary rehabilitation programs.
