The aim of this study was to determine the effects of a 2-day prenatal course of indomethacin on the premature kidney as reflected by serum creatinine and urinary biomarkers.  Urine of infants ≤ 32 weeks was collected for the first 14 days and analyzed for cystatin C, neutrophil gelatinase-associated lipocalin, osteopontin, β2 microglobulin, epidermal growth factor, uromodulin, and microalbumin. Bivariate analysis compared serum creatinine and biomarkers of exposed (INDO) and unexposed (CONT) subjects.  Fifty-seven infants (35 CONT and 22 INDO) were studied. The cohorts were similar in gestational age, birthweight, race, gender, nephrotoxic medication exposure, and Apgar scores. CONT had more dopamine exposure and included more pre-eclamptic mothers (  = 0.005). No difference in creatinine-based acute kidney injury or the log transformed mean, maximum, and minimum values of urinary biomarkers was detected.  Our findings suggest that a short course of tocolytic indomethacin does not result in neonatal acute kidney injury. · A short prenatal course of indomethacin does not result in neonatal AKI.. · Urinary EGF might have a promising role as a more sensitive biomarker for early detection of AKI in premature infants..
