This observational study assessed whether measurements of certain pro-inflammatory and anti-inflammatory cytokines in the blood (either singly or in combination) at birth and/or up to day of life 21 can predict cerebral palsy at 18-22 months corrected age.

Further study details as provided by NICHD Neonatal Research Network:

Primary Outcome Measures:
  • Pro-cytokines increased and anti-inflammatory cytokines decreased [ Time Frame: At birth and/or up to Day 3±1 ]

Secondary Outcome Measures:
  • Type and severity of CP and other neurodevelopmental handicaps, the appearance of PVL, and neonatal mortality [ Time Frame: 18-22 months corrected age ]
  • Abnormal pro-inflammatory and anti-inflammatory cytokines at birth are associated with prenatal insults (e.g., chorioamnionitis, occult intrauterine infection, early-onset neonatal sepsis, perinatal asphyxia, early death) [ Time Frame: At birth ]
  • Abnormal postnatal cytokine levels associated with postnatal insults (e.g., postnatal intraventricular hemorrhage, late-onset neonatal sepsis, bronchopulmonary dysplasia, chronic lung disease, and/or necrotizing enterocolitis) [ Time Frame: Up to Day of life 21 ]
  • Pro-inflammatory cytokine elevations at the time of a workup for possible sepsis occur in infants with a positive bacterial blood culture and those with negative blood cultures who are treated with a full course of antibiotics [ Time Frame: Up to Day of life 21 ]

Detailed Description:

Inflammatory cytokines [interleukin-1 (IL-1β), IL-8, IL-9, tumor necrosis factor-α (TNF-α), and RANTES] but not anti-inflammatory cytokines released during the perinatal period have been associated with the development of periventricular leukomalacia (PVL) and cerebral palsy (CP) in near term and term infants. However, because blood samples were obtained on any day between day 1 and 18, these data cannot distinguish between prenatal and postnatal effects on neurological outcome. Furthermore, very low birth weight infants who are at the highest risk have not been studies.

The goal of this study was to measure pro-inflammatory and anti-inflammatory cytokine levels at various times in the perinatal period (at birth up to day of life 21), since they may be elevated at different points in the disease process. Blood samples (whole blood spots, dried on filter paper) were obtained on day 1 within 4 hours after birth, and on days 3, 7, 14, and 21. Neurodevelopmental assessments were conducted at 18-22 months corrected age.
