BACKGROUND: Though cyclosporine has dramatically decreased rejection rates and improved graft survival rates of renal allografts, there is still a remarkable rate of acute rejection and progressive deterioration of renal function after transplantation. Rescue therapy with tacrolimus has been used for allografts failing under cyclosporine-based treatment in order to get some renal functional recovery or stabilization. The aim was to evaluate tacrolimus rescue therapy for failing allografts under cyclosporine-based immunosuppression for possible prediction factors for success. PATIENTS AND METHODS: Thirty-five renal allograft recipients with failing transplants under cyclosporine-based immunosuppression were enrolled into this study. Renal function was evaluated by reciprocal serum creatinine level( 1/Cr) and calculated CCr. The slope of changes in 1/Cr and CCr were calculated before and after tacrolimus therapy. The possible risk factors that affect the outcome of tacrolimus rescue therapy were analyzed. RESULTS: Nineteen patients showed improved renal function (group 1) and 16 patients, persistent deterioration (group 2) after rescue therapy. Group 1 showed positive slopes of changes of 1/Cr and CCr after rescue therapy. Group 2 patients showed persistent negative slopes although less negative than before rescue therapy. Only the posttransplant time was the significant predictive factor for successful tacrolimus therapy (P = . 018). CONCLUSION: Tacrolimus rescue therapy improved or stabilized renal function in some patients with failing grafts under cyclosporine-based immunosuppression. To assure a successful rescue effect , it should be given early after transplantation, if there is a tendency toward deterioration of renal function ; 醫學系外科 ; 醫學系 ; 醫學院 ; 期刊論文
