METHODS:Thirty patients undergoing LTx received initial steroid-free immunosuppression.Indication for LTx included 7 patients with HCV related cirrhosis.Initial immunosuppression consisted of tacrolimus 2×0.05mg/kg.d po and mycophenolate mofetil(MMF)2×15mg/kg.d po.The tacrolimus dosage was adjusted to trough levels in the target range of 10-15μg/L during the first 3 mo and 5-10μg/L thereafter.Manifestations of acute rejection were verified histologically. RESULTS:Patient and graft survival of 30 patients receiving initial steroid-free immunosuppression was 86% and 83% at 1 and 2 years.Acute rejection occurred in 8/30 patients, including 1 HCV infected recipient.All HCV-infected patients had HCV genotype Ⅱ(lb).HCV seropositivity occurred within the first 4 mo after LTx.The virus load was not remarkably increased during the first year after LTx.Histologically,grafts had no severe recurrent hepatitis. CONCLUSION:From our experience,initial steroid-free immunosuppression does not increase the risk of acute rejection in HCV infected liver recipients.Furthermore,none of the HCV infected patients developed serious chronic liver diseases.It suggests that it may be beneficial to avoid steroids in this particular group of patients after LTx.展开更多
