INTRODUCTION: Immunosuppressive protocols containing everolimus (EVR) preserve good renal function in kidney transplantation (KT), although they are often complicated by several adverse events. We have evaluated the efficacy and safety of a protocol with late (1 month after KT) EVR introduction.MATERIAL AND METHODS: This study randomized 49 de novo patients undergoing KT between September 2012 and June 2014 into 2 groups: group A (n = 24) with late EVR introduction and tacrolimus reduction, and group B (control group; n = 25) with a standard immunosuppressive regimen. Primary aims were 1-year patient and graft survivals and acute rejection rates. Secondary aims were related to wound, metabolic, and hematologic complications.RESULTS: Patient and graft survivals were similar in both groups. One year after KT, median serum creatinine was inferior in group A (1.4 vs 1.8 mg/dL; P = .004). Late acute rejection (8.3 vs 12.0%; P = 1.0) and wound complication (4.2 vs 4.0%; P = 1.0) rates were similar. Higher cholesterol and triglycerides and lower platelets and hemoglobin levels were observed in group A.CONCLUSIONS: In our experience, delayed introduction of EVR shows similar results with respect to its early introduction, contemporaneously presenting fewer wound complications and lymphoceles. A higher rate of metabolic and hematologic complications are, however, observed in patients under EVR therapy. Further multicenter studies should be performed to confirm these preliminary results.
