24 month follow up to a late conversion from a calcineurin inhibitor regimen to everolimus in kidney transplant recipients

Introduction: Graft survival has remained stable in the long term, without significant increase in recent years. Among the main causes of renal graft loss after the first year are death with functioning kidney graft from cardiovascular, infectious and neoplastic causes, and chronic graft injury for immunological and non-immunological causes. This has been attributed to the chronic use of calcineurin inhibitors (CNI), increased cardiovascular risk, the incidence of certain infections and increased incidence of post-transplant malignancies. Also, reports show the increased frequency of histological lesions related to nephrotoxicity caused by these drugs. The switch from CNI to mTOR inhibitors may decrease some of these effects in the long term. We conducted a retrospective study of conversion to mTOR inhibitors in patients with a CNI-based scheme.
