To investigate the effects of tacrolimus-based immunosuppression regimens after orthotopic liver transplantation and search a reasonable regimen of combination therapy and suitable blood concentration of tacrolimus.


Ninety-four adult recipients of cadaveric livers were randomly divided into 3 groups to undergo different tacrolimus-based immunosuppression regimens: dual (tacrolimus + glucocorticoid), triple [tacrolimus + mycophenolate mofetil (MMF) + glucocorticoid]; quadruple [tacrolimus + MMF + glucocorticoid in addition of induction treatment by daclizumab]. The efficacy and safety of the 3 groups 6 months after the transplantation were compared.


The frequencies of acute rejection were 25.9%, 11.1%, and 7.5% for the dual, triple, and quadruple therapy groups, that of the quadruple therapy group being significantly lower than that of the dual therapy group (P = 0.038). There were no significant differences in the rates Three months after transplantation, the levels of ALT and total cholesterol of the dual therapy groups were significantly higher than those of the quadruple therapy group (P(ALT) = 0.011, P(Tch) = 0.002). Within the first month post-operatively the concentration of tacrolimus of the triple therapy group could be controlled at the level 8 ng x ml(-1)-13 ng x ml(-1).


Quadruple tacrolimus-based immunosuppression regimen is the most effective and safest, followed by the triple therapy and dual therapy. Low-dose tacrolimus combination therapy provides an effective protection to the liver graft with mild drug toxicity to the patient.
