    Abstract:
    BACKGROUND: Corticosteroids have been used traditionally for immunosuppression after solid organ transplantation. The variety of modern immunosuppressive agents offers the chance to replace drugs with an unfavorable risk-benefit ratio. The objective of this prospective pilot study was to investigate a novel steroid-free immunosuppressive regimen after clinical liver transplantation. METHODS: 30 adult liver graft recipients were included in an intent-to-treat analysis. Dual induction immunosuppression consisted of tacrolimus and mycophenolate mofetil. Prophylactic steroids were not given. Efficacy and safety parameters analyzed were patient and graft survival, incidence and severity of rejection, and adverse events in correlation to immunosuppressive drug levels. RESULTS: Patient and graft survival at 2 years was 86.7 and 83.9%, respectively. Acute rejection occurred in 26.2%, and was associated with subtherapeutic tacrolimus blood levels and diarrhea. All rejections were completely reversible by temporary addition of steroids. Acute renal failure was seen in 10/30 patients, and was related to high tacrolimus blood levels together with primary liver graft dysfunction. 43% of all patients never received any steroids, and 73% were on a steroid-free maintenance regimen. CONCLUSIONS: These results confirm that corticosteroids can be completely avoided from the beginning after liver transplantation. Double drug immunosuppression with tacrolimus and mycophenolate mofetil is effective and safe in terms of patient and graft survival as well as incidence and severity of rejection. In order to avoid under- or over-immunosuppression, which may be caused by impaired absorption or metabolism, close drug monitoring is advised.
