Abstract

OBJECTIVE:

To evaluate the risk of nonsteroidal anti-inflammatory drug (NSAID) therapy-associated acute kidney injury (AKI) among neonates diagnosed with patent ductus arteriosus (PDA) who are treated with gentamicin.

STUDY DESIGN:

Multicenter retrospective observational study of patients ≤ 44 postmenstrual weeks of age diagnosed with PDA who received gentamicin during hospitalization between January 2006 and December 2014. Patients with and without NSAID exposure were matched on covariates associated with AKI and NSAID therapy. The primary end point, AKI, was defined according to Kidney Disease Improving Global Outcomes neonatal criteria.

RESULTS:

The rate of AKI for the entire cohort (n = 594) was 12% (n = 71). Among neonates receiving NSAIDS, 14.8% (n = 44) experienced an AKI as compared to 9.1% (n = 27) for those who were not exposed (relative risk, 1.6; 95% confidence interval, 1.0 to 2.6). Therefore, the attributable risk of NSAID use was 5.7% (95% confidence interval, 0.5 to 11.0).

CONCLUSION:

Among neonates with PDA and receiving gentamicin, NSAID therapy increases the risk of AKI by about 6%.
