Outcomes in pediatric hepatitis C transplant recipients: analysis of the UNOS database.

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.
