Quality of life after living donor liver transplant for biliary atresia in Japan

Background Health-related quality of life (HRQOL) is an important outcome in solid organ transplantation. This study evaluated and explored the factors of generic and transplant-specific HRQOL in Japanese pediatric and adolescent patients with biliary atresia (BA) after living donor liver transplant (LDLT). Methods A cross-sectional survey using anonymous questionnaires was completed between April and July 2015. Patient medical records were accessed. The Japanese version of Pediatric Quality of Life InventoryTM Generic Core Scales and Transplant Modules (child self-report and parent proxy-report) was administered. Results Participants consisted of 75 patients (mean age at survey, 9.6 years) and 74 parents. Japanese patients reported higher generic and transplant-specific HRQOL (total score) than that reported by US patients with BA after LT (US I; age at survey, 7.2 years) and by US patients after solid organ transplant (US II; age at survey, 11.3 years; LT, 53.8%; effect size, 0.55–0.96). Japanese parents, however, rated their children's generic HRQOL (total score) similar to that rated by the US I and II parents (0.13 and 0.30, respectively) and reported lower transplant-specific HRQOL (total score) than that reported by US II (0.26). Although the number of types of prescribed drugs was a common factor in HRQOL, most demographic and medical factors (e.g. child's age at survey and consultation frequency) varied with reporter (i.e. patients and parents). Conclusions The levels and factors of generic and transplant-specific HRQOL of Japanese pediatric and adolescent patients with BA after LDLT varied with reporter (i.e. patients or parents).
