Perinatal infection is an important risk factor for cerebral palsy in very-low-birthweight infants
1Queen Elizabeth Hospital, King's Lynn, Norfolk, UK.
Insights
Neonatal sepsis significantly increases cerebral palsy (CP) risk in very-low-birthweight infants. Cranial ultrasound findings correlate with CP subtypes, with abnormal ultrasounds linked to hemiplegia and normal ultrasounds to diplegia.
Area of Science:
- Neonatal neurology
- Pediatric neurology
- Developmental pediatrics
Background:
- Cerebral palsy (CP) is a significant concern in very-low-birthweight (VLBW) infants.
- Neonatal factors like sepsis and cranial ultrasound findings may influence CP development and subtypes.
Purpose of the Study:
- To investigate the relationship between neonatal sepsis, cranial ultrasound abnormalities, and the development of CP subtypes in VLBW infants.
- To determine the impact of sepsis on CP risk, irrespective of initial brain imaging results.
Main Methods:
- Retrospective cohort study of 923 VLBW infants.
- Follow-up at 18 months to diagnose CP.
- Analysis of neonatal cranial ultrasound findings (abnormal vs. normal).
- Assessment of CP subtypes (hemiplegia, diplegia) in relation to ultrasound results and sepsis history.
Main Results:
- Out of 923 VLBW infants, 69 developed CP.
- Infants with abnormal neonatal ultrasounds predominantly had hemiplegia (39 cases).
- Infants with normal neonatal ultrasounds predominantly had diplegia (30 cases).
- Neonatal sepsis was associated with a fourfold increased risk of CP, regardless of ultrasound findings.
Conclusions:
- Neonatal sepsis is a strong independent risk factor for CP in VLBW infants.
- Cranial ultrasound findings in the neonatal period can help predict CP subtypes.
- Early identification of risk factors like sepsis is crucial for VLBW infant neurodevelopmental outcomes.
Abstract:
Sixty-nine very-low-birthweight infants out of a population of 923 had cerebral palsy (CP) at an 18-month follow-up. Thirty-nine of these had cranial ultrasound abnormalities in the neonatal period and 30 had normal cranial ultrasounds. The distribution of subtypes of CP differed markedly between the two groups, with hemiplegia predominating in those with abnormal cranial ultrasounds and diplegia in those with normal cranial ultrasounds. Regardless of ultrasound appearance, the relative risk of CP increased approximately fourfold with a neonatal history of sepsis.
