title: Use of basiliximab with mycophenolate mofetil in kidney transplantation.
abstract: BACKGROUND
  Randomized, placebo-controlled studies have determined that administration of basiliximab (chimeric IL-2 receptor antagonist) decreases the acute rejection rate in kidney transplantation when used in combination with cyclosporine, azathioprine, and steroids. We report our experience using basiliximab with mycophenolate mofetil, a calcineurin inhibitor, and steroids in kidney transplantation.
  
  
  METHODS
  We retrospectively analyzed 127 patients who received their first kidney transplant between September 1, 1998, and December 30, 2000, including 59 who received basiliximab (22 living and 37 cadaveric donor recipients) and the 68 that did not receive this antibody (31 living and 37 cadaveric donor recipients). The groups were demographically comparable for risk factors such as race, peak of panel-reactive antibody, delayed graft function, donor age, and cold ischemia time. The analysis assessed serum creatinine levels, acute rejection, cytomegalovirus infection, and posttransplant lymphoproliferative disease incidence as well as patient and graft survival at 6 months.
  
  
  RESULTS
  Serum creatinine levels were 3 +/- 3.1 and 2.6 +/- 2.5 mg/dL (P =.346) at discharge, 1.5 +/- 0.6 and 1.7 +/- 1.1 mg/dL (P =.098) at 1 month, and 1.5 +/- 0.7 and 1.6 +/- 0.7 mg/dL (P =.454) at 6 months posttransplantation for patients treated with versus without basiliximab, respectively. Only one episode of acute rejection was seen among patients treated with basiliximab within 1 month posttransplantation versus three episodes among patients treated without basiliximab (P =.382). Three patients (5.1%) treated with basiliximab and two patients (2.9%) treated without basiliximab developed acute rejection within 6 months posttransplantation (P =.536). Patient and graft survivals at 6 months posttransplantation were not significantly different between patients treated with versus without basiliximab (100% and 100% versus 100% and 98.3%, respectively). There was no increased incidence of cytomegalovirus infection with the use of basiliximab (5.1% vs 5.9%, P =.844). There was only one case of posttransplant lymphoproliferative disease within 6 months posttransplantation in a patient treated without basiliximab.
  
  
  CONCLUSIONS
  These data suggest that the routine addition of basiliximab to a mycophenolate mofetil-based regimens does not appear to be warranted. A larger prospective randomized study with longer follow-up is needed to confirm these results.
