Potential for creatine or melatonin as dietary supplements in pregnancy to prevent perinatal brain damage [ 2006 - 2008 ]

Brief description Brain damage in the newborn - particularly in prematurely born infants - remains a significant health problem. At present there are very few treatments that can be used to minimize damage when it becomes apparent in the newborn, and none that can be used PROSPECTIVELYduring pregnancy to protect the developing brain from damage. The most likely cause of damage to the fetal brain during pregnancy or at birth is global ASPHYXIA, either by itself or in association with other problems of pregnancy such as infection, preterm birth, or fetal growth retardation. In this project we propose that providing extra amounts of the dietary constituent creatine, or of the hormone melatonin, to the pregnant animal in late gestation, will provide NEUROPROTECTION to the developing brain in the face of an asphyxial challenge that otherwise causes damage. We will use pregnant sheep to investigate the effects of asphyxia in utero on the fetal brain using techniques that allow us to monitor metabolic changes within the brain in real time. In addition, we will use the pregnant Spiny Mouse to investigate the effects of birth asphyxia on the postnatal brain structure and behavioral development. We will study groups of animals fed a normal diet, and compare then to animals that receive additional amounts of creatine or melatonin. We expect to determine if either of these treatments have the potential to protect the developing brain from asphyxial damage, and to recommend if similar treatments could be used in pregnant women where the obstetrician suspects the baby's brain is at risk of damage.
