Reduced Recurrence of Primary IgA Nephropathy in Kidney Transplant Recipients Receiving Everolimus With Corticosteroid: A Retrospective, Single-Center Study of 135 Transplant Patients

Research output: Contribution to journalArticle

Abstract

Background: Long-term kidney allograft survival remains a major clinical challenge. Recurrent glomerulonephritis disease, including recurrence of IgA nephropathy (IgAN), is a significant barrier to long-term kidney allograft survival. We performed a retrospective, observational study to evaluate the role of everolimus (EVR) in the risk of recurrent IgAN. Methods: The study included data from 135 patients aged ≥16 years with biopsy-proven IgAN on native kidneys who underwent a kidney transplant (KT) between December 2002 and December 2018. Results: Patients who underwent de novo KT received mycophenolate mofetil (MMF) (n = 107) or EVR (n = 28). The mean recipient age in the MMF and EVR groups was 44.9 ± 13.7 and 41.1 ± 10.1, respectively. The median (interquartile range) follow-up period was 90.9 (64.9-115.3) and 21.2 (11.4-30.6) months, respectively (<.0001). All patients received continuous corticosteroid and tacrolimus therapy. The death-censored graft survival rate after KT and the recurrence-free survival rate did not differ significantly between the groups. Univariate and multivariate Cox regression analyses identified EVR for de novo KT as an independent predictive factor for recurrence-free survival (P =.024). Conclusions: Our findings suggest that EVR-based regimens with tacrolimus and corticosteroid therapy for de novo KT reduce the recurrence of IgAN compared with MMF-based regimens with tacrolimus and corticosteroid therapy.
