Long-term mycophenolate mofetil monotherapy in combination with calcineurin inhibitors for chronic renal dysfunction after liver transplantation.

摘要

BACKGROUND: Calcineurin inhibitors (CNIs) are the first-line immunosuppressive agents administered after liver transplantation, but they cause renal impairment. Two recent randomized trials report cellular rejection and liver graft loss when mycophenolate mofetil (MMF) monotherapy was used as a renal-sparing agent. Our experience with MMF in the same setting but with longer follow-up is described. METHODS: In 45 patients with serum creatinine more than 120 micromol/L or creatinine clearance less than 50 mL/min, 2 g MMF per day was administered (median 29 months, 1-49 months) either as monotherapy (with all other immunosuppression withdrawn in 1 month) in 16 patients (group I) or in combination with low-dose CNI (trough tacrolimus
