Delayed calcineurin inhibitor introduction and renal outcomes in liver transplant recipients receiving basiliximab induction.

Background: To investigate the impact of delayed calcineurin inhibitor (CNI) initiation in liver transplant recipients (LTR) with peri-operative renal insufficiency receiving basiliximab induction, we compared renal outcomes of LTR stratified by the degree of achieved post-operative renal recovery (RR) prior to CNI initiation.
Methods: All adult LTR transplanted between 01/2007 and 12/2015 who received basiliximab were included. Patients who received multi-organ transplantations, were repeat transplant recipients, or expired prior to post-operative day (POD) 90 were excluded. The primary outcome of our retrospective analysis was renal function at POD 90.
Results: A total of 210 patients were included in our final analysis. Most patients were Caucasian males undergoing liver transplantation for liver disease secondary to hepatitis C virus. Baseline characteristics were similar among the evaluable population. Estimated GFR was significantly higher among patients with the greatest degree of post-operative renal recovery at POD 90; however, this difference did not persist at POD 180. There was no significant difference in incidence or severity of biopsy-proven acute rejection (BPAR) at any measured time point.
Conclusions: Delayed CNI initiation following liver transplantation in patients with post-operative renal insufficiency who receive basiliximab induction does not adversely affect the incidence of BPAR or long-term renal outcomes.
