First human double hand transplantation: efficacy of a conventional immunosuppressive protocol.

Based on the results achieved in single human hand transplantations, we decided to perform the first double hand transplantation with a conventional immunosuppressive protocol in a patient with a high potential for functional recovery. Two years after transplantation the efficacy and the safety of this immunosuppressive protocol are evaluated. The recipient was a 33-yr-old man suffering from a traumatic amputation of both hands in 1996. Five HLA-A, -B, and -DR mismatches were present with the donor; T and B cell cross-match was negative. Immunosuppressive protocol included tacrolimus, prednisone, mycophenolate mofetil and, for induction, antithymocyte globulins and then anti CD25 monoclonal antibody. Reconstitution of lymphocyte populations proceeded normally. Neither anti-HLA antibodies nor chimerism in peripheral blood were detected. Two episodes of acute rejection characterized by maculopapular lesions occurred on days 53 and 82 after transplantation. Skin biopsies revealed a dermal lymphocytic infiltrate. Both episodes were completely and rapidly reversed by topical clobetasol and increased systemic corticosteroid therapy. The only side-effects related to treatment were reversible serum sickness and hyperglycemia. No infectious complications and malignancies occurred. No signs of graft-versus-host disease have been detected. This case of double hand transplantation shows that conventional immunosuppression is effective and safe to ensure survival and functional recovery of the grafted limb.
