Use of Tacrolimus and MTOR Inhibitors With Anticipatory Therapy vs. Tacrolimus and Mycophenolic Acid With Universal Prophylaxis in Renal Recipients at High Risk of Posttransplant Cytomegalovirus.

Patients receive immunosuppressive induction treatment with thymoglobulin (at least 1 dose and maximum of 5 doses) and immunosuppressive maintenance treatment with tacrolimus + mTOR inhibitors. Preemptive therapy will be administered as a preventive strategy, consisting of initiating antiviral treatment with valganciclovir (900 mg every 12 hours, adjusted according to renal function as per the technical data sheet) when CMV viral replication in blood exceeds 1,000 copies/ml. Treatment will be discontinued once viral load becomes undetectable in two consecutive tests.

Patients will receive immunosuppressive induction treatment with thymoglobulin (at least 1 dose and a maximum of 5 doses) and tacrolimus + mycophenolic acid following the guidelines of the technical file and the centre's usual protocols.
