Alpha-1 Antritypsin Deficiency (ATD) is a heterogeneous disease, and is an important indication for liver transplantation (LT) in children. We examine the ATD population requiring LT and their outcomes in the pediatric end-stage liver disease (PELD) era.
Children ≤18 years old that had a first isolated LT for ATD were identified from the UNOS database from 3/2002-12/2012. Comparisons were made based on age and gender. Recipient, transplant, and donor characteristics were analyzed.
5,140 children underwent LT in the study period. 113 (2.2%) children underwent LT for ATD. Recipient, transplant and donor characteristics are detailed in Table 1. Bilirubin and INR at transplant were significantly higher in the 0-2 year group than in the older cohorts. This youngest group also had more transplants for status 1; 18.9% versus 0%. Of the 10 patients listed as status 1, 70% were male and 90% were < 1 year old.
Patient survival at 1 year was 86.8%, 100%, and 97.9% for the youngest, middle and oldest groups respectively. 5 year patient survival was 84.9%, 100%, and 97.9%, respectively. Early graft survival (≤14 days) was significantly worse in the youngest group; 81.1% versus 91.7% and 100% in the middle and older groups (p<0.01). Younger donor age was identified as a risk factor for graft loss with thrombosis as the most common cause.
Survival in the PELD era was high for children undergoing LT for ATD. Children age <2 had worse coagulopathy and cholestasis, were more likely to be listed as status 1, and had increased rates of early graft loss.
