    Abstract:
    BACKGROUND: Addition of the interleukin-2 receptor (IL-2R) antagonists basiliximab or daclizumab to a calcineurin inhibitor-based regimen significantly reduces risk of acute rejection with a tolerability profile similar to a placebo. Use of a truncated two-dose regimen of daclizumab has been reported, but till date, there has been no controlled study of two-dose daclizumab vs. two-dose basiliximab. METHODS: Deceased-donor renal transplant recipients were randomized to basiliximab (20 mg on days 0 and 4) or daclizumab (50 mg on days 1 and 14) with cyclosporine, mycophenolate mofetil and corticosteroids. Flow cytometry was used to calculate the proportion of CD25(+) T cells in peripheral blood. RESULTS: Thirty patients were randomized to basiliximab and 28 to daclizumab. There was one patient death in each group, with no other graft losses. By six months, the incidence of biopsy-proven acute rejection was 0% with basiliximab vs. 21.4% with daclizumab (p < 0.05). Three patients in the daclizumab group required OKT3 for steroid-resistant rejection. There were no between-group differences in the incidence of infection. The proportion of CD25(+) T cells declined markedly during the first two wk in both groups, but was significantly lower in the basiliximab group during weeks six to eight. CONCLUSION: Two doses of basiliximab are more effective than two 1 mg/kg doses of daclizumab in preventing acute rejection in de novo renal transplant patients receiving cyclosporine, mycophenolate mofetil and corticosteroid maintenance therapy. In patients receiving relatively low-level immunosuppression in order to minimize toxicity, basiliximab may be preferable to a truncated daclizumab regimen.
