Abstract:  An anti-CD25 monoclonal antibody was added to thymoglobulin for induction therapy in simultaneous pancreas/kidney (SPK) recipients. T-cell subsets including CD3 and CD25 were assessed by flow cytometry analysis in the peripheral blood of SPK (n = 88), and for comparison kidney transplant (KT) recipients were assessed. KT recipients were treated with daclizumab (anti-CD25) alone (five doses; 1 mg/kg) (n = 27) or thymoglobulin alone (4–7 doses; 1 mg/kg) (n = 23). SPK recipients received daclizumab (two doses; 1 mg/kg) in addition to thymoglobulin (five doses; 1 mg/kg). The return of peripheral blood CD25+ cells was delayed for 45 d post-transplantation in the SPK recipients where anti-CD25 was added to thymoglobulin, compared to those KT recipients with thymoglobulin alone. This strategy may result in reduced allogeneic (donor-specific) T effector cells at the time of solid organ transplantation.
