The influence of mTOR inhibitors on the incidence of CMV infection in high-risk donor positive/recipient negative (D+/R-) kidney transplant recipients.
TRANSPLANT INFECTIOUS DISEASE(2018)
摘要
IntroductionSeveral studies and meta-analysis suggest the mTOR inhibitors are associated with reduced incidence of CMV infection after kidney transplantation, although their effects on the high-risk population have not been investigated thoroughly. ObjectiveThis retrospective cohort study investigates the association between immunosuppression and CMV infection in D+/R- kidney transplant recipients receiving preemptive therapy. MethodsAll patients received rabbit anti-thymocyte globulin, tacrolimus, prednisone and azathioprine (AZA), mycophenolate (MPA) or everolimus (EVR). ResultsAmong 89 D+R-, the overall incidence of CMV infection was 76%, with no difference among the groups AZA vs MPA vs EVR (73 vs 83 vs 74%, P=0.643). CMV infection occurred later (31 in AZA vs 31 in MPA vs 43days in EVR group, P<0.001) and showed a lower trend of recurrences (57% in AZA vs 79% in MPA vs 48% in EVR group, P=0.058) in the everolimus group. There were no differences in the IgG seroconversion rate (82% in AZA vs 76% in MPA vs 72% in EVR group, P=0.983). There were no differences in the incidence of biopsy-proven acute rejection (10% in AZA vs 8% in MPA vs 6% in EVR group, P=0.811) and renal function at 12months (53.6 in AZA vs 60.3 in MPA vs. 55.4mL/min/1.73m(2) in EVR group). ConclusionIn this cohort of high-risk CMV D+/R- kidney transplant recipients receiving rATG induction and tacrolimus, the use of mTOR inhibitors could only show a tendency towards but not a significant difference on the incidence of CMV events, when compared to antimetabolites.
