Neonatal Infection in Children With Cerebral Palsy: A Registry-Based Cohort Study

Area of Science:

• Neurology
• Pediatrics
• Neonatology

Background:

• Cerebral palsy (CP) is a complex neurological disorder impacting motor function.
• Neonatal infections are a potential risk factor for adverse neurodevelopmental outcomes.
• Understanding the specific associations between neonatal infection and CP phenotypes is crucial for targeted interventions.

Purpose of the Study:

• To investigate the relationship between neonatal infection and the clinical characteristics of cerebral palsy.
• To compare phenotypic profiles of children with CP, with and without a history of neonatal infection.
• To explore differences in these associations based on gestational age (term vs. preterm).

Main Methods:

• Retrospective cohort study utilizing the Canadian Cerebral Palsy Registry.
• Neonatal infection defined by septicemia, septic shock, or prolonged antibiotic use (≥10 days).
• Phenotypic profiles analyzed, with subgroup analysis by gestational age.

Main Results:

• 15.6% of children with CP experienced neonatal infection, higher in preterm infants (29%) than term infants (6.5%).
• Neonatal infection associated with white matter injury, spastic diplegia, and auditory impairment in children with CP.
• In term-born infants with CP, neonatal infection linked to spastic triplegia/quadriplegia, combined brain injuries, and more severe motor impairment.

Conclusions:

• Systemic infection during the neonatal period may influence brain development, particularly in term infants.
• Findings suggest potential for developing targeted therapies and preventive measures to reduce CP-related morbidity.
• Further research can refine strategies for managing infants at risk for CP following neonatal infection.
