Excellent outcome with a calcium channel blocker-supplemented immunosuppressive regimen in cadaveric renal transplantation. A potential strategy to avoid antibody induction protocols.

Many transplant centers routinely utilize monoclonal antibody or polyclonal antibody based induction protocols in recipients of cadaver renal allografts. Given the potential complications associated with antibody-based immunosuppression regimens (e.g., CMV disease), we tested the hypothesis that a combination of a calcium antagonist and a triple drug protocol (cyclosporine+ prednisone+azathioprine) would be an effective substitute for antibody-based induction protocols in ensuring excellent patient and graft survival rates. Our postulate was tested in a prospective study of 52 consecutive recipients of cadaver renal allografts (44 first, 5 second, and 3 third grafts) utilizing nifedipine as the first line calcium antagonist
