Growth and quality of life after living-related liver transplantation in children

Abstract

Fifty-six consecutive pediatric recipients surviving more than 3 yr after living-related liver transplantation (LRLT) were evaluated in terms of growth, quality of life (QOL) and need for maintenance immunosuppression. Significant improvement in Z-score for height and weight were observed at last follow-up, ranging from 3 to 6 yr after transplantation, although catchup height gain lagged behind recovery in weight (height: -1.77 pre-transplant to -0.77 post-transplant, p<0.001; weight: -1.12 pre-transplant to -0.18 post-transplant, p<0.0001). 82% (46) recipients have remained in good health and have an excellent QOL as assessed in the most recent 6 months; these children lead similar daily lives to normal healthy children, with daily school attendance and full participation in activities including gymnastics and hiking. 3.6% (2) recipients attended school regularly but were unable to participate in sporting activities. 14% (8) recipients remain home or hospital-bound due to persistent complications in the past 6 months, with only minimal school attendance. Less than 10% of recipients were taking steroids by 2 yr post-transplantation, although approximately half of the children were receiving low-dose maintenance steroids at 1 yr. The mainstay immunosuppressant was tacrolimus, with 68% (38) recipients receiving daily therapy, 8.9% (5) alternate-day, 8.9% (5) twice a week, and 5.4% (3) a single dose weekly or alternate weeks. 7.1% (4) recipients were withdrawn completely from all immunosuppressants, including tacrolimus, for various reasons. 8.9% (5) patients have needed multiple immunosuppressive agents over the last 6 months. In conclusion, LRLT restores growth and offers excellent quality of life in pediatric recipients. The majority of recipients require minimal, steroid-free, immunosuppression by 2 yr post-transplant, but the occasional recipient still needs intensive longterm immunosuppression.
