Calcineurin inhibitor-free immunosuppressive strategy in elderly recipients of renal allografts from deceased donors: 1-year results from a prospective single center trial

Transplant Proc. 2009 Jul-Aug;41(6):2529-32. doi: 10.1016/j.transproceed.2009.06.151.

Abstract

Recently published data from our center have demonstrated the feasibility of a nephrotoxicity- and atherogenicity-free, mycophenolate mofetil (MMF)-based immunosuppressive protocol for elderly recipients of kidneys from elderly cadaveric donors. We investigated a therapeutic regimen of strictly monitored MMF (target mycophenolic acid [MPA] trough levels between 2-6 microg/mL) and steroids combined with a polyclonal-monoclonal induction regimen consisting of a low-dose, single shot of rabbit ATG (ATG-Fresenius) and the interleukin-2 receptor (IL-2R)-antibody basiliximab (d0 and d4). Between 1997 and 2007, we treated 175 elderly patients with an MMF-based, calcinearin inhibitor (CNI)-free immunosuppressive protocol. For the present cohort, 30 elderly recipients (67.8 +/- 3.8 years) of renal transplants from deceased donors (69.4 +/- 13.3 years) were recruited consecutively for this 5-year prospective, open, single center, pilot trial. One-year results of this clinical trial were patient and renal allograft survivals of 87% and 83%, respectively; death-censored 1-year graft survival was 97%. Mostly steroid-sensitive rejection episodes were observed in 46% of patients, with only 3 patients requiring serum antibody therapy. Renal allograft function was satisfactory, as reflected by a mean serum creatinine of 1.78 +/- 0.45 mg/dL and a Nankivell glomerular filtration rate (GFR) of 48.8 +/- 13.9 mg/dL at 6 months. Twenty-three percent of all patients demonstrated cytomegalovirus (CMV) infections; however, only 3.3% developed CMV disease. Application of a combined polyclonal-monoclonal induction regimen using a nephrotoxicity- and atherogenicity-free, MMF-based immunosuppressive maintenance protocol in elderly cadaveric kidney transplant recipients led to acceptable short-term outcomes, albeit at the expense of an increased rejection rate, comparable to that previously published for elderly (>50 years) recipients of allografts from elderly (>50 years) cadaveric donors.
