Kidney transplantation has become the treatment of choice for both the quality of life and survival in patients with end-stage renal disease (ESRD). However, the immunosuppressive regimen which allows optimal kidney transplant outcome remains elusive. One of the more promising induction agents, Alemtuzumab, was introduced to kidney transplantation by Calne in the late 1990s with low dose cyclosporine A monotherapy, with the hope of establishing 'prope' or near tolerance. Subsequent pilot studies with Alemtuzumab alone or monotherapy (DSG, Rapa) demonstrated high rates of acute rejection (AR) along with occasional humoral components that lead to abandoning the concept of Alemtuzumab as a 'magic bullet' to achieve tolerance, prope or otherwise. A number of programs (including our own) has since modified maintenance immunosuppression using low dose tacrolimus, and shown acceptable rates of AR, with relatively low incidence of viral infection and lymphoproliferative disorders along with cost benefit. However, there are only three prospective, randomized studies which are small with one year or less follow-up, and most published series utilize historical control groups with relatively short follow-up. As extrapolation from short-term data is far from secure, long-term, prospective, randomized studies with Alemtuzumab will be necessary to determine the optimal immunosuppressive regimen.
