Abstract

The aim of the study was to investigate the occurrence of fatigue in 100 pediatric liver transplant recipients aged 2-18 years and its impact on their health-related quality of life (HRQL). HRQL and fatigue were measured using the PedsQL 4.0 Inventory and the PedsQL Multidimensional Fatigue Scale, which encompasses three subscales: general fatigue, sleep/rest fatigue, and cognitive fatigue. The impact of the different domains of fatigue and of clinical and sociodemographic factors on the HRQL was identified with stepwise multiple regression analyses. Parent proxy-reports were available for all 100 participants (2-18 years), and child self-reports were available for 71 patients (8-18 years). Across all domains, participants and their parents reported significantly more fatigue than healthy peers in a large PedsQL validation study. Thirty-seven percent of patients and 57% of parents scored clinically relevant levels of fatigue. In the multiple regression analyses, none of the clinical and sociodemographic factors contributed to the HRQL for child self-report. Only general and cognitive fatigue were significant predictors of patients' HRQL, explaining 66% of the variance in the PedsQL total score. For parent proxy-report, general and cognitive fatigue also significantly predicted child's HRQL. Further predictors were child's age and family income. The regression model explained 65% of the variance. These findings demonstrate the importance of assessing fatigue during regular follow-up examinations. Further research is urgently needed to better understand the underlying mechanisms of fatigue. Improvement of fatigue symptoms is essential for better HRQL, for cognitive functioning, and for school achievement.
