Cytomegalovirus disease in de novo kidney-transplant recipients: comparison of everolimus-based immunosuppression without prophylaxis with mycophenolic acid-based immunosuppression with prophylaxis
Abstract
Purpose: To compare everolimus (EVR) plus low-dose tacrolimus (TAC) with mycophenolic acid (MPA) plus standard-dose TAC with regards to rates of cytomegalovirus (CMV) disease in de novo kidney-transplant recipients (KTRs).
Methods: This single-center retrospective study included 187 de novo KTRs; 59 patients (31.6%) received EVR/low-dose TAC (group 1); 128 patients (68.4%) received MPA with standard-dose TAC (group 2). All received anti-thymocyte globulins as the induction therapy, and steroid-sparing strategy. Valganciclovir prophylaxis was mandatory for CMV D+/R- KTRs (seronegative recipients of a seropositive donor) in both groups and for R+ seropositive recipients (only in group 2).
Results: The 2-year incidence of CMV disease was low and comparable between groups: 6.8% and 7.0% in groups 1 and 2, respectively (p = 0.94). There was no statistical difference in CMV serostatus (p = 1). However, CMV disease tended to be less frequent, though not statistically different, in R+ KTRs receiving EVR without prophylaxis (3.7% vs. 8.5% in groups 1 and 2, respectively) and in patients without EVR discontinuation (2.6% vs. 6.9% in patients who did not discontinue MPA (p = 0.29). Two-year graft function was good and comparable between groups (median eGFR of 54.2 and 53.0 mL/min in groups 1 and 2, respectively; p = 0.47); incidence of immunological events was low. Significantly more patients in group 1 discontinued EVR because of adverse events than patients that discontinued MPA in group 2 (35.6% in group 1 vs. 10.2% in group 2; p < 0.001).
Conclusions: Everolimus plus low-dose TAC given to de novo KTRs was associated with low rates of CMV disease, especially in R+ patients with no CMV prophylaxis.
