    Abstract:
    INTRODUCTION: Sirolimus is a potent immunosuppressant with a mechanism of action different from calcineurin inhibitors (CNIs). It has increasing importance for liver transplant (OLT) patients, in particular if when there is decreased renal function. We evaluated the efficacy and the causes for discontinuation of sirolimus-based immunosuppression among OLT recipients. OBJECTIVE: We retrospectively analyzed 97 liver transplanted patients who were prescribed sirolimus as the principal immunosuppressant. Of these, 61 patients discontinued treatment. Herein we have reported the causes, the timing, and the effects of sirolimus discontinuation. RESULTS: The overall patient survival at 3 years follow-up was 89%. Hepatotoxicity and blood disorders were the most frequent, severe reported side effects. Acute cellular rejection episodes appeared in seven patients and was relieved in 1 to 2 weeks after the sirolimus administration. In 10 patients, the cholestasis associated with chronic rejection was sharply reduced after the introduction of sirolimus. No increase in vascular thrombosis and/or poor wound healing were reported. CONCLUSION: Sirolimus given alone or in combination with CNIs appears to be an effective primary immunosuppressant regimen for OLT patients. However, in the late postoperative period (>3 months) the drug is associated with a relatively high rate of side effects.
