Basiliximab Induction with Delayed Calcineurin Inhibitors for High-Risk Lung Transplant Candidates.

PURPOSE: Calcineurin inhibitor (CNI) use has improved lung transplantation outcomes. However, significant perioperative complications in patients receiving CNI can deteriorate the early course of lung transplantation. To date, there is no consensus regarding the optimal agent for the induction regimen after lung transplantation. We aimed to determine the efficacy of basiliximab induction with delayed CNI initiation in the prevention of acute complications without compromising immunosuppression in high-risk patients.

MATERIALS AND

METHODS

Between January 2013 and December 2019, 236 patients at a single lung transplant center were retrospectively reviewed. Forty-one patients (17.4%) received basiliximab induction, and 195 patients (82.6%) received a routine triple-drug regimen without induction. The primary endpoint was postoperative acute kidney injury with several other postoperative outcomes as secondary end-points.

RESULTS

Preoperatively, the induction group had a higher proportion of patients who were admitted before transplantation (95.1% vs. 47.7%, p<0.001) and received intensive unit care (90.2% vs. 33.8%, p<0.001) and extracorporeal membrane oxygenation (ECMO) (87.8% vs. 20.0%, p<0.001) compared to the non-induction group. No significant differences were observed in the incidence of acute rejection between groups (p=0.657), although lower incidence of postoperative complications, including acute kidney injuries or culture-proven infections, were observed in the induction group. However, the differences were not statistically significant. A subgroup analysis of high-risk and preoperative ECMO support groups showed similar results.

CONCLUSION

Basiliximab induction with delayed CNI initiation for high-risk patients might decrease the incidence of perioperative complications, including acute renal failure, without increasing the risk of acute rejection.
