    Abstract:
    To assess the efficacy and safety of a primary immunosuppressive regimen with tacrolimus (Tac) and low-dose mycophenolate mofetil (MMF) without steroids and to determine the exposure to mycophenolic acid (MPA) in the early postoperative period, we performed a single-center, randomized 1:1, open-label, controlled study planned to be 60 liver transplantation patients randomized into 2 groups: group A, tacrolimus + MMF (750 mg orally twice a day); and group B, tacrolimus + MMF (750 mg orally twice a day) + steroids. After an interim analysis by the ethical committee patient enrollment was stopped. Data from 30 patients (12 in group A and 18 in group B with a mean follow-up period of 31 +/- 7 months) showed a patient survival rate of 91.7% in group A and 100% in group B and a graft survival rate of 91.7% and 88.9%, respectively. Nine patients (75%) in group A suffered an acute rejection episode, whereas in group B only 3 patients (16.7%) showed acute rejection (P = .002). All rejection episodes occurred in both groups at 1 week after transplantation. The difference in histological grading was statistically significant (P = .021). The toxicity profiles were similar in both groups. A primary immunosuppressive regimen based on Tac and low-dose MMF without steroids is safe but unable to prevent acute rejection at 1 week after transplantation even if early acute rejection does not affect the outcome in terms of morbidity and graft or patient survival.
