Neurovascular Unit Alterations In The Growth Restricted Newborn Are Improved Following Ibuprofen Treatment

Fetal brain development is particularly vulnerable to the effects of fetal growth restriction (FGR) and abnormal neurodevelopment is common in the FGR infant. Adverse outcomes range from behavioural and learning disorders through to cerebral palsy. Unfortunately, no treatment exists to protect the FGR newborn brain. Recent evidence suggests inflammation may play a key role in the mechanism responsible for the progression of brain impairment in the FGR newborn, including disruption to the neurovascular unit (NVU). We explored whether ibuprofen, a non-steroidal anti-inflammatory drug, could reduce NVU disruption and brain impairment in the FGR newborn. We used a preclinical piglet model of growth restriction in which FGR occurs spontaneously. Newborn FGR (birthweight
