Hematopoietic stem cell transplant (HSCT) is the only accepted treatment capable of halting the progression of X-linked cerebral adrenoleukodystrophy (CALD). While survival and neurological outcomes have been described, there is little information regarding the quality of life (QoL) of transplanted patients with CALD. This analysis is a cross-sectional study of QoL in 16 males diagnosed with CALD who underwent HSCT at a single institution. Each child or parent proxy completed subscales from the Neuro-QoL and the PROMIS Pediatric Profile Instrument representing physical, mental, and social health domains. Descriptive statistics summarized the demographic characteristics and QoL subscale T-scores, Spearman Rho correlations identified the relationships among the variables, and Mann-Whitney tests examined group differences between those with pre-HSCT Loes scores 10. The median age of respondents at the time of transplant was 8 years at HSCT (5-14) with a median of 5 years since HSCT (0.5-11). Scores from the selected QoL subscales were similar to healthy peers, though those with pre-HSCT Loes scores >10 had lower mobility, upper extremity function, peer interaction, and higher scores for anxiety. Although HSCT has the capability of halting progression of CALD, those with pre-HSCT Loes scores >10 after HSCT are at-risk for poor QoL. Longitudinal monitoring is necessary to further appreciate the factors affecting QoL among boys with CALD after HSCT, and how this may be improved.
