Abstract

The aim of this study in renal transplant recipients was to compare a tacrolimus plus mycophenolate mofetil (MMF) immunosuppressive regimen with a combination of low dose of cyclosporine and everolimus.Sixty consecutive patients were prospectively assigned to receive tacrolimus and MMF (TAC; n = 30) or everolimus and low-dose cyclosporine (EVL; n = 30). Tacrolimus was dosed seeking a trough blood level of 8 to 10 ng/mL by month 3 and 5 to 8 ng/mL thereafter. Everolimus was dosed seeking a trough blood level of 3 to 8 ng/mL by day 7. Cyclosporine was dosed aiming at a C2 blood level of 350 to 700 ng/mL in the first week and 150 to 400 ng/mL thereafter. All patients received induction with basiliximab and maintenance treatment with corticosteroids.At 6-months follow-up, patient survival rates (TAC 100% vs EVL 100%) and graft survival rates (TAC 96.7% vs EVL 93.3%) were not significantly different between the groups. Patients in the EVL group showed more acute rejection episodes, but serum creatinine concentrations and creatinine clearances were not significantly different from the TAC group. Among the observed side effects, hypercholesterolemia was significantly higher in the EVL group (total cholesterol: TAC 206 +/- 38 vs EVL 250 +/- 55 mg/dL; P < .003).This study showed that the immunosuppressive association of tacrolimus and MMF produced similar acute rejection episodes, graft survivals, and renal function at 6 months after renal transplantation compared with an immunosuppressive combination of everolimus and low-dose cyclosporine. Dyslipidemia was significantly greater among patients who received everolimus.
