With the increased incidence and survival of lung transplant (LTx) recipients, the risk for chronic sequelae such as chronic kidney disease (CKD) is on the rise. Data on the long-term renal outcome are scarce. We performed a retrospective chart review of 171 adults with LTx from January 1, 2014, to January 1, 2019. Primary outcomes were prevalence of CKD/end-stage renal disease, acute kidney injury (AKI) as a risk factor for future CKD, and all-cause mortality in recipients with CKD compared with the non-CKD group. Secondary outcomes were frequency of utilization of modalities for CKD (urinalysis, imaging, biopsy, nephrology consultations). Baseline median creatinine and estimated glomerular filtration rate (eGFR) were 0.8 mg/dL and 90 mL/min/1.73 m2, respectively. Of the participants, 60% (96 of 161), 67% (102 of 153), 79% (37 of 47), 86% (10 of 12) had CKD at the end of 6, 12, 36, and 60 months, respectively, and 16% were on dialysis at the end of the study period; 3% received a subsequent renal transplant, and 27% mortality was noted over a 5-year follow-up period. The odds of CKD development in patients with an AKI during index hospitalization vs no AKI was 6.22 (2.87 to 13.06, P < .0001). The odds ratio of all-cause mortality in patients with CKD compared with non-CKD was 3.36 (95% confidence interval, 1.44-8.64, P = .005). Measurement of hematuria/proteinuria, imaging, and renal biopsy were infrequently used. Given the high prevalence of AKI and CKD in this population, a multidisciplinary team approach with an early nephrology consultation will be key to improve the overall and renal outcomes in LTx recipients.
