Mycophenolate mofetil-based, cyclosporine-free induction and maintenance immunosuppression: first-3-months analysis of efficacy and safety in two cohorts of renal allograft recipients.

Abstract：

BACKGROUND:The currently used macrolide immunosuppressants, i.e., cyclosporine and tacrolimus, exert considerable nephrotoxicity. We aimed to avoid the nephrotoxic effects by applying a cyclosporine-free regimen for the induction as well as for the maintenance treatment of renal allograft recipients using mycophenolate mofetil (MMF) as the primary immunosuppressant. METHODS:Thirteen patients were converted from cyclosporine (CsA) to MMF monotherapy. For 4 weeks, MMF (2 g/day) was added to the CsA treatment, before CsA was tapered by weekly steps of 25 mg/day and without "safeguard treatment" with additional immunosuppressants. In a second approach, 12 patients older than 50 years, and receiving a renal graft from a donor older than 50 years, were treated primarily with MMF combined with steroids and an induction therapy using antithymocyte globulin, and without the addition of CsA. RESULTS:Thirteen long-term renal transplant patients could be converted from CsA to MMF monotherapy. Conversion resulted in an immediate and long-lasting improvement of their median creatinine values by 20%. No serious adverse events occurred. In the second cohort of 12 patients, MMF was used as the primary immunosuppressant. All patients are alive and no grafts were lost after 4 months (n= 12) and after 6 months (n=7). The median creatinine values achieved after 4 and 6 months were 1.16+/-0.25 and 1.30+/-0.21 mg/dl, respectively. One patient was converted to CsA because of a reversible rejection episode (8.3%), and another patient was converted because of cytomegalovirus disease. Major complications consisted of wound-healing disturbances (16.6%) and cytomegalovirus infections (41.6%). CONCLUSION:MMF monotherapy can be safely applied as long-term maintenance immunosuppression with improvement of renal function. Steroids are not required as an adjunct to MMF. MMF monotherapy, in the absence of drug-related nephrotoxicity, is particularly beneficial for grafts derived from marginal donors, such as donors of advanced age.
