To analyze our results with mycophenolate mofetil (MMF) in stable liver transplantation (LT) patients presenting with adverse events (AE) related to prolonged use of calcineurin inhibitors (CNI).


Conversion to MMF was performed in 56 out of 323 LT patients from 91-02: 24 (43%) were converted to MMF in monotherapy and 32 (57%) to MMF+low doses of CNI. The indication for conversion was chronic renal insufficiency (CRI) in all patients. The mean time between AE and conversion was 38.7+/-30 months (r: 2-101 m). Post-conversion follow-up was 39+/-20 months (r: 3-72 m).


The calculated creatinine clearance (Crauckoft), improved significantly in all patients. In those converted to MMF, improvement was seen during the first 18 months for urea and during the first 6 months for creatinine. In patients converted to MMF+CNI, improvement was maintained throughout the conversion period for both urea and creatinine. Eleven (19.6%) patients underwent acute rejection (2 severe episodes in the MMF group and 1 death). Hypertension was present in 31 patients but only improved in 4 (7%). Dyslipemia was found in 12 and improved in 4 (7%). DM was present in 14 and improved in 1 (2%).


Conversion to MMF in monotherapy is useful in stable LT patients with CRI due to CNI, although this result is offset by more severe rejections. Therefore, for AE secondary to CNI, we propose an early conversion to MMF+low doses of CNI as a first step. If liver function remains stable and AEs persist or progress, conversion to MMF in monotherapy is recommended, as a second step, with close monitoring of the patient.
