Lack of differences in outcomes between 3 immunosuppression protocols in the first year after pediatric liver transplantation: A multicenter study.

Abstract

Advances in immunosuppression have extended patient and graft survival rates after solid organ transplantation; however, this is not free of side effects. Balancing safety and efficacy is of paramount importance, particularly in the pediatric setting. Current literature comparing different protocols is scarce, and decisions are mostly guided by physician preference. We aimed to compare 3 different protocols from 4 different centers to identify differences in outcomes after 1 year of follow-up. A retrospective analysis of the databases of the participating centers was performed. Consecutive patients aged <18 years with a first liver-only transplant and no other underlying congenital or acquired immunodeficiency were included. Patients were classified according to the immunosuppression protocol as follows: group A (prednisone + tacrolimus + basiliximab), group B (prednisone + tacrolimus + basiliximab + antithymocyte globulin), and group C (prednisone + tacrolimus). Differences in survival, frequency of rejection, infections, and other complications were analyzed in the entire group (n = 97) and the group with biliary atresia (n = 48). After 1 year of follow-up, no differences in patient or graft survival were observed when comparing either the entire group (n = 97) or patients with biliary atresia only (n = 48). The frequencies of rejection and episodes of infection were similar. Renal function showed no differences either before or after transplantation or between the groups. Immunosuppression protocols used in this study appeared to be equally safe and effective. This could offer the opportunity to tailor them to the patient's individual characteristics without compromising the outcome.
