HCV may lead to the development of ESLD in late childhood and, consequently, contributes to the need for liver transplantation. The aim of this study was to examine post-transplant outcomes in HCV-positive pediatric patients with ESLD from any cause and to determine the impact of the PELD scoring system, introduced in February 2002, on post-transplant patient and graft survival. A retrospective analysis of the UNOS database from 1994 to 2010 was performed to assess graft and patient survival in pediatric HCV-seropositive liver transplant recipients. Graft survival and patient survival comparing subjects in the pre-PELD era and post-PELD era were analyzed using Kaplan-Meier statistics. Factors associated with survival were identified using Cox regression analysis. Of 120 pediatric HCV transplant recipients, 80 were transplanted in the pre-PELD era and 40 were transplanted post-PELD. Median serum total bilirubin, INR, and creatinine were 4.8 mg/dL, 1.6, and 0.7 mg/dL in the pre-PELD era vs. 5.5 mg/dL, 1.7, and 0.6 mg/mL, respectively, in the post-PELD era (p NS). One-yr graft survival in the pre-PELD vs. post-PELD era was 65.0% and 89.7%, respectively (p < 0.01); corresponding three-yr graft survival was 57.3% vs. 76.2% (p = 0.04). One-yr patient survival in the pre-PELD vs. post-PELD era was 79.0% and 97.5%, respectively (p < 0.01); corresponding three-yr survival was 79.0% vs. 89.4% (p = 0.17). Twenty-eight patients (23.3%) were retransplanted: 24 (30%) in the pre-PELD era (median time to retransplant 272 days) and four (10%) in the post-PELD era (median time to retransplant 586 days). Early follow-up demonstrates a trend toward improved pediatric HCV liver transplant graft and patient survival in the post-PELD era. Superior outcomes may be attributed to pretransplant factors, improved surgical technique and better treatment options for HCV infection.
