Abstract

BACKGROUND: Basiliximab is an anti-CD25 monoclonal antibody used as induction therapy in solid-organ transplantation. In this study we aim to determine whether pre-operative administration of basiliximab is beneficial in preventing early heart allograft rejection. METHODS: In this investigation we assess the effect of pre-implantation basiliximab on CD25 count and on acute rejection in children undergoing cardiothoracic transplantation. The notes of all children undergoing cardiothoracic transplantation at the Great Ormond Street Hospital between January 2000 and June 2007 were retrospectively reviewed. One hundred twenty-one heart transplant recipients were included: 29 patients did not receive basiliximab; 33 patients received basiliximab after coming off cardiopulmonary bypass (CPB); and 59 patients received basiliximab prior to organ implantation. RESULTS: All patients receiving basiliximab had an effectively suppressed CD25 count (<0.2%) on Days 1 and 10 post-transplant. Freedom from Grade 3A or greater rejection in the first year was significantly greater in the pre-implantation basiliximab group than in the post-implantation and no-basiliximab groups (95%, 70% and 72%, respectively; p = 0.02). Induction regimen was the only significant explanatory variable after multivariate Cox regression. CONCLUSIONS: The results of this study confirm that basiliximab is effective at suppressing CD25 count whether given pre- or post-CPB. Basiliximab before transplantation appeared to reduce acute rejection, whereas post-CPB administration did not suggest similar effects. These findings require independent validation in randomized trials and further studies should seek to mechanistically delineate these observations.
