Funding Cincinnati Children's Hospital Center for Acute Care Nephrology provided funding to create and maintain the Assessment of Worldwide Acute Kidney Injury Epidemiology in Neonates (AWAKEN) study Medidata Rave electronic database. The Pediatric and Infant Center for Acute Nephrology (PICAN) provided support for web meetings and for the Neonatal Kidney Collaborative (NKC) steering committee annual meeting at The University of Alabama at Birmingham (UAB), as well as support for two of the AWAKEN study investigators at UAB (D.A., R.G., and L.B.). PICAN is part of the Department of Pediatrics at UAB and is funded by Children's of Alabama hospital, UAB Department of Pediatrics, UAB School of Medicine, and UAB Center for Clinical and Translational Sciences (National Institutes of Health grant UL1TR001417). Finally, the AWAKEN study at The University of New Mexico was supported by the Clinical and Translational Science Center at The University of New Mexico (National Institutes of Health grant UL1TR001449) and by The University of Iowa Institute for Clinical and Translational Science (grant U54TR001356). The AWAKEN study investigators at the Canberra Hospital at the Australian National University Medical School were supported by the Canberra Hospital Private Practice Fund, and investigators at University of Virginia Children's Hospital were supported by a 100 Women Who Care Grant from the 100 Women Charitable Foundation. The funding sources for this study had no role in the design and conduct of the study; collection, management, analysis, and interpretation of the data; preparation, review or approval of the manuscript, and decision to submit the manuscript for publication.

Abstract

Objective This study aimed to evaluate the association between acute kidney injury (AKI) and lung outcomes in infants born ≥32 weeks of gestational age (GA).

Study Design Secondary analysis of infants ≥32 weeks of GA in the assessment of worldwide acute kidney injury epidemiology in neonates (AWAKEN) retrospective cohort (n = 1,348). We used logistic regression to assess association between AKI and a composite outcome of chronic lung disease (CLD) or death at 28 days of age and linear regression to evaluate association between AKI and duration of respiratory support.

Results CLD occurred in 82/1,348 (6.1%) infants, while death occurred in 22/1,348 (1.6%); the composite of CLD/death occurred in 104/1,348 (7.7%). Infants with AKI had an almost five-fold increased odds of CLD/death, which remained after controlling for GA, maternal polyhydramnios, multiple gestations, 5-minute Apgar's score, intubation, and hypoxic–ischemic encephalopathy (adjusted odds ratio [OR] = 4.9, 95% confidence interval [CI]: 3.2–7.4; p < 0.0001). Infants with AKI required longer duration of respiratory support (count ratio = 1.59, 95% CI: 1.14–2.23, p = 0.003) and oxygen (count ratio = 1.43, 95% CI: 1.22–1.68, p < 0.0001) compared with those without AKI.

Conclusion AKI is associated with CLD/death and longer duration of respiratory support in infants born at ≥32 weeks of GA. Further prospective studies are needed to elucidate the pathophysiologic relationship.
