BACKGROUND: Recent technologic advances in neonatal dialysis have changed current dialysis practices. The goal of this study was to define demographics, diagnoses, initial dialysis modality, modality changes, and outcomes of neonates receiving dialysis.
METHODS: Retrospective, multicenter cohort of neonates (≤ 30 days of age) from 26 U.S. centers, who received dialysis between 6/2017 and 5/2022. Measures of central tendency were calculated to describe the cohort stratified by the primary dialysis-related diagnosis including acute kidney injury requiring dialysis (AKI-D), stage 5 chronic kidney disease (CKD 5), hyperammonemia, and other causes. The primary outcome was death during the initial hospitalization.
RESULTS: For the 405 neonates in this cohort, AKI-D (57%) was the most common dialysis-related diagnosis, followed by CKD 5 (29%) and hyperammonemia (11%). Most neonates (58%) had a birth weight between 2500 and 3500 g. The most common initial neonatal dialysis modality was continuous kidney replacement therapy (CKRT) with (35%) or without extracorporeal membrane oxygenation (ECMO) (36%). Only 26% of neonates received peritoneal dialysis (PD) as their initial dialysis modality. Thirty percent of neonates received more than one dialysis modality. The overall mortality was 50% (59% in AKI-D and 41% in CKD 5). Withdrawal of care was reported as the most common reason for death. The odds of death were lower for neonates with AKI-D receiving PD as the initial modality when compared to CKRT (aOR 0.28, 95% CI 0.09-0.84) or CKRT with ECMO (aOR 0.24, 95% CI 0.10-0.58), but this association was not seen in neonates with CKD 5.
CONCLUSIONS: This multicenter, contemporary neonatal dialysis cohort shows increased use of CKRT as the initial dialysis modality but also shows that the mortality of neonates on dialysis remains high. Additional studies on modern neonatal dialysis are needed.
