Abstract

BACKGROUND: Outcome data for infants on chronic peritoneal dialysis (CPD) is limited and has been based primarily on the analyses of voluntary entry registry data. In contrast, the United States Renal Data Systems (USRDS) collects data on all infants with end-stage kidney disease (ESKD) on chronic dialysis in the USA. We aimed to describe the clinical characteristics of this population and to determine the associated patient mortality.

METHODS: The USRDS database was reviewed retrospectively for data on infants who initiated CPD at ≤ 12 months of age from 1990 to 2014. Infants were categorized into four groups, CPD initiation age (≤ 1 month of age or neonates and > 1-12 months of age or older infants) and initiation era (1990-1999 and 2000-2014).

RESULTS: A total of 1723 infants (574 neonates and 1149 older infants) were identified. Overall, 20.9% of infants (147 neonates and 213 older infants) died on dialysis during the follow-up. The most commonly identified causes of death on dialysis were cardiorespiratory disease (25.8%) and infection (22.8%). There was an increased risk for mortality in all infants who initiated CPD in the earlier initiation era (1990-1999) vs the later era (2000-2014) (aHR of 1.95), for females vs males (aHR 1.43), and for those with a primary diagnosis of cystic kidney diseases vs congenital anomalies of the kidney and urinary tract (CAKUT) (aHR 1.84). In 2000-2014, patient survival at 1 and 5 years was 86.8% and 74.6% for those who initiated CPD as neonates and 89.6% and 79.3% for those who did so as older infants.

CONCLUSIONS: In this large cohort of infants who received chronic peritoneal dialysis over more than two decades, the probability of survival after initiating CPD in the first year of life has significantly improved. There is no difference in the probability of death for neonates compared to older infants. However, the mortality rate remains substantial in association with multiple risk factors.
