Acute kidney injury in infants with hypothermia‐treated hypoxic‐ischaemic encephalopathy: An observational population‐based study

Aim To describe incidence and outcome of acute kidney injury (AKI) in infants with hypothermia‐treated hypoxic‐ischaemic encephalopathy (HIE). Methods This observational population‐based study included all term and near‐term infants with hypothermia‐treated HIE born between 2007 and 2009 in greater Stockholm. The KDIGO definition modified for neonatal patients was used to identify infants with AKI. We analysed association between AKI and neonatal morbidity/mortality. Furthermore, we calculated estimated glomerular filtration rate (eGFR) at the age of 10–12 years. Results Out of 83,939 live births in the Stockholm region, 66 infants underwent hypothermia treatment due to HIE. Out of 65 included infants, 45% suffered AKI. Degree of AKI correlated with HIE severity. One infant needed kidney replacement therapy; others were treated conservatively. AKI was associated with increased mortality and need for blood products (p
