Abstract Introduction Recipients of Hematopoietic Cell Transplantation (HCT) are at risk for treatment related late effects including cardiovascular disease and diabetes. Physical fitness including mobility and muscle strength are important predictors of cardiovascular health and quality of life. Physical fitness has been described in children and adults who are long term survivors of HCT for malignant disease [1]. Patients with sickle cell disease (SCD) are likely to be subject to unique morbidity post-HCT as a consequence of the pathophysiology of SCD which is characterized by anemia, inflammation, pain, bone infarcts and neurological complications. A systematic assessment of physical fitness is required to understand some of the long-term outcomes HCT for SCD. Methods We enrolled patients with SCD ≥ 1-year post-HCT in Sickle Transplantation Evaluating Long Term And Late Effects Registry (STELLaR). We assessed physical fitness including mobility using the timed up and go (TUG) test, and muscle strength using the handgrip strength (HGS) test. TUG scores were compared with published normative data for children (mean 9.2s; SD = 0.8) and young adults (mean 10.5s, SD = 1.1) [2]. TUG scores ≥ mean+ 2SD were considered abnormal (children: ≥10.8s, young adults ≥12.7s). The HGS of each patient was compared to published normative data of children and adults [3,4]. Patients ≤12 years were abnormal if they had a HGS of two standard deviations below the mean. Patients ≥13 years were considered abnormal if they had a HGS lower than the lower limit of the 85% age-sex standard. Additionally, patients were also assessed for chronic graft versus host disease (cGvHD) by means of the Lee Chronic GvHD Symptom Scale [5]. Patients rated their extent of being bothered by cGvHD symptoms on a scale from 1 to 5, with 1 being not at all and 5 being extremely. These scores were then organized into 7 categories of cGVHD symptoms and normalized to a 0-100 scale. We report the results of an interim analysis of physical fitness in these HCT recipients. Results Out of 121 patients enrolled in the study, 37 HCT recipients were assessed for mobility using the TUG test, and for muscle strength using the HGS test. Children were defined as being below the age of 18 and young adults between 18 and 40 years of age. Patient demographic and clinical results for TUG and HGS are presented in Table 1. Young adult participants were more likely to have abnormal TUG and HGS results than pediatric study participants. Patient self-reporting of overall (summary) cGvHD symptoms was found to be statistically significant between children and young adults (p=0.037) with young adults iappearing to be slightly more bothered by GvHD symptoms. There was no correlation in length of time in years between a patient's transplant and whether or not there was abnormal physical fitness (TUG and HGS) for both the young adult and children cohorts. Conclusions These data suggest the existence of impaired physical fitness in the long term in SCD patients who are HCT recipients. They provide the rationale for systematic evaluation of physical fitness and other risk factors for cardiovascular disease post-HCT. References 1. Slater, M. E., Steinberger, J., Ross, J.
