Rationale. Perioperative acute kidney injury (AKI) after bilateral orthotopic lung transplantation (BOLT) is associated with significant morbidity. In this international, multicenter study of patients undergoing primary BOLT, we describe the perioperative characteristics and outcomes of recipients who develop severe AKI. Methods. The Extracorporeal Life Support (ECLS) in lung transplantation registry includes data on BOLT patients from 9 high volume (>40 transplants/yr) transplant centers (2 from Europe, 7 from United States). Adult BOLT recipients from Jan 2016 to Nov 2020 with complete 48-hour creatinine (Cr) values were included. We excluded patients with primary pulmonary hypertension, mean PAP≥40mmHg, dialysis history, underwent multi-organ or redo transplantation, or concomitant cardiac surgery. Patients were grouped by whether they developed severe AKI, defined as increased Cr >2x baseline (>Gr2 by RIFLE criteria) or dialysis use. Secondary outcomes included primary graft dysfunction (PGD) at 24, 48, and 72 hours, postoperative ECMO use, reintubation, tracheostomy, intraoperative urine output (UOP), length of stay (LOS), and death at 90 days and 1 year. Donor, recipient, and operative characteristics were compared between groups. Multiple logistic regression analyses were performed after adjustment for several covariates. Results. Five hundred eighty-nine BOLT patients were included. Of those, 509 did not develop severe AKI (no severe AKI group), while 80 (13.6%) were in the severe AKI group. Dialysis during the index hospitalization was required in 46% (N=37) of recipients who developed severe AKI. Comparisons between groups are displayed in Table 1a. Recipients with severe AKI had higher LAS, higher mean PA pressures, right ventricular dysfunction, and less likely to have a donor who smoked. Severe AKI patients had longer ischemic times, reduced intraoperative UOP, intraoperative ECLS and received more red blood cell transfusions. Worsened secondary outcomes were observed in the severe AKI group. Table 1b describes the association of severe AKI to secondary outcomes. For every unit increase in ΔCr relayed an estimated 12 day increase in LOS (12.24 d±2.35, p=0.001). Adjusted multivariate analysis showed higher risk of mortality in the severe AKI group at 90 days (OR 0.07, 0.02-0.26, p< 0.0001) and 1 year (OR 0.12, 0.05-0.26, p=<0.0001). Conclusion. In this multicenter international registry, 13.6% of select, low risk lung transplant patients developed severe AKI, with 46% of the severe AKI cohort requiring dialysis during the index hospitalization. Recipients with perioperative severe AKI have associated worsened PGD, 161% longer LOS, and increased mortality.
