Abstract
Background Mycophenolate mofetil (MMF) is a cornerstone immunosuppressive drug after liver transplantation (OLT). The aim of this study was to evaluate the long term results of the addition of MMF in maintenance OLT recipients. Methods From 1996 to 2006, MMF was introduced because of (1) histologic features of rejection or (2) calcineurin inhibitor (CNI) toxicity in order to reduce CNI dosage. Results The study population included 208 patients (median, age 54 ± 9 years), with a median delay between OLT and MMF introduction of 54 ± 43 months. The median dosage of MMF was 1180 mg/d at the end of follow-up. After a median follow-up of 50 ± 26 months, 26.4% of the patients taking MMF did present ≥1 side effect and MMF discontinuation rate was 13.8% (transient in 3.8%). The main side effects were digestive disorders (45%), pruritus ± rash ± mucitis (12.7%), and myelosuppression (16.4%). MMF was withdrawn because of digestive disorders (17.2%), pruritus ± rash ± mucitis (17.2%), and myelosuppression (24.1%). The mean glomerular filtration rate as calculated by the Cockcroft-Gault formula value significantly increased after the introduction of MMF (58.1 vs 71.4 mL/min; paired t-test; P < .01). Improvement of renal function was significantly associated with initial association with tacrolimus (vs cyclosporine), initial trough level of cyclosporine (not tacrolimus), delay between OLT and MMF introduction, and age of renal impairment. Conclusion Our results suggest that the introduction of MMF in OLT maintenance recipients is efficient and well-tolerated (one quarter of the patients presented significant side effects, leading to treatment discontinuation in 10% of the patients).
