Introduction: There is no standard of care immunosuppressive regimen for recipients of kidneys recovered from expanded criteria donors. Several centers use r-ATG induction due to the higher risk of delayed graft function and acute rejection, increasing the risk of CMV infection.
Objectives: This study compares the efficacy and safety of EVR or MPS in ECD kidney transplant recipients. Methods: This is a prospective, randomized, single center study designed to enroll 200 patients (1:1) to receive r-ATG induction (4 doses of 1.5 mg/kg every other day), prednisone, EVR or MPS and delayed introduction of TAC (day 7) to maintaim trough blood concentrations around 5 ng/ml. This preliminary analysis was performed with 127 randomized patients (EVR n=68 and MPS n=59) who completed 6 months of follow up. Preemptive strategy using pp65 antigenemia test was use to manage CMV infection. Results: There were no differences in mean kidney donor profile index (KDPI, 89±9 vs. 89±8%) and mean kidney donor risk index (KDRI, 1.7±0.4 vs. 1.7±0.3) comparing EVR and MPS groups, respectively. There were no differences in main demographic characteristics except for the incidence of diabetes mellitus (EVR, 38% vs. MPS, 15%). There was no difference in incidence of delayed graft function (54 vs. 64%, p=0.253) but duration was lower in MPS group (11.1 ±11.9 vs. 5.0±4.6 days, p= 0.004). The incidence of first CMV infection was lower in EVR group (12 vs. 76%, p=0,000). Furthermore, 36% of patients in MPS (n=21) developed at least one recurrent event of CMV infection. Higher incidence of treated acute rejection (36 vs. 23%, p=0.165) or treated biopsy confirmed acute rejection (18 vs. 10%, p=0.197) was observed in the EVR group. At 6 months mean estimated glomerular filtration rate was higher in the MPS group (MRDR, 38.1±16.2 vs. 48.1±14.8 mL/min, p=0.003). Treatment discontinuation was higher in the MPS group (18% vs. 32%), primarily due to recurrent CMV infections. Conclusions: This preliminary analysis indicates that patients receiving EVR show lower incidence of CMV infection but higher incidence of acute rejection and lower renal function compared to patients receiving MPS.
