This is a pilot study to test feasibility and safety of intravenous infusion of autologous umbilical cord blood cells in the first 72 hours after birth if a neonate is born with signs of encephalopathy.
Hypoxic ischemic encephalopathy (HIE) occurs in ~ 2-4/1000 term infants and is a major cause of neonatal morbidity and mortality. To date, therapeutic hypothermia started within 6 h of birth is the only intervention known to be effective in reducing the morbidity and mortality of HIE. Hypothermia does not totally reverse the injury in many infants and is associated with side effects that may compromise its effectiveness. Low dose morphine is often used to reduce shivering in infants undergoing therapeutic hypothermia, but escalating doses of sedatives/analgesics are often required. Escalating doses of opioids and benzodiazepines causes respiratory depression and can either cause the need for or prolong mechanical ventilation.Agonists to the central a2 - adrenergic receptors are more effective at reducing postoperative shivering than opioid receptor agonists and provide analgesia and sedation without respiratory depression. The most desirable sedative-analgesic agent used in infants with HIE would: (a) have an excellent safety profile, (b) reduce shivering, (c) provide adequate analgesia and sedation, (d) cause minimal respiratory depression, (e) preserve cerebrovascular autoregulation, and (f) confer neuroprotection.
The primary objective of HOPE is to improve the accuracy of outcome prediction in anoxic-ischemic encephalopathy following cardiac arrest by bringing under close scrutiny some of the existing methods used for this purpose (e.g. somato-sensory evoked potentials). HOPE is the first multicenter prospective cohort study on coma prognosis to control for the effect of a possible self-fulfilling prophecy at the ICU and to cover the acute and neurorehabilitation phases with a long-term follow-up longer than the usual three or six months.
LEVNEONAT is a multicentre French clinical trials with the aim to develop new treatment strategies for the treatment of neonatal seizures using Levetiracetam. The purpose of this study is to determine the correct dosing, safety and efficacy for intravenous levetiracetam as first line treatment in term newborn babies with seizures in hypoxic-ischemic encephalopathy context. This new anticonvulsivant drug is a promising treatment for seizures in newborns.
This study examines the effect of inhaled xenon gas in the treatment of newborn infants with hypoxic-ischemic encephalopathy (HIE) in combination with cooling, which is the standard treatment for this condition. The hypothesis is that the xenon + cooling combination will produce better neuroprotection than the standard treatment of cooling alone.
1 in 1000 babies are born suffering from a lack of oxygen. This is known as hypoxic ischemic encephalopathy (HIE). Infants with this condition can suffer multiple organ problems. In particular it can affect how their hearts pump blood around their body thus leading to a poor blood supply to parts of their body such as the brain. This is known as circulatory failure and can contribute to poor long term outcomes such as cerebral palsy. To try and prevent brain damage these infants are treated with total body cooling, however this treatment can further effect how babies pump blood around the body, but also how drugs which may be used by in this condition are processed. In order to assess and treat this condition doctors need to be able to accurately measure the blood supply in an infant. However there is no agreement on how best to do this. This makes decisions about when to treat an infant difficult. Sometimes doctors may want to use drugs such as dobutamine or adrenaline but these drugs are unlicensed in babies. This study proposes to observe the way babies circulatory problems are treated in babies with HIE the in the first four days of life. In addition the study will look are two new measurements of a babies blood supply to see if they are a better measure of when an infant needs treatment. This will involve an ultrasound scan of the heart and measurement of the baby's oxygen levels from a probe placed on their hand. The study will also look at how the drug dobutamine is processed by babies. This will be done from two small extra blood tests. The aim of the study is to help clinicians refine the identification and treatment of circulatory failure in babies with HIE.
Despite recent advances in the care of mothers and newborn infants, many infants (approximately 20 per 1000 live births) continue to need resuscitation at birth. A proportion of these infants will have sustained significant injury through interruption of their blood and oxygen supply prior to delivery (perinatal asphyxia). In 2-3 babies per 1000 this will lead to brain swelling and the risk of long term brain injury called neonatal hypoxic-ischaemic encephalopathy (HIE). HIE remains a cause of neonatal death and long term disability. Early and accurate prediction of outcome would allow us to intervene during the window of the first 6 hours following birth, prior to secondary reperfusion and secondary brain injury. Estimating severity of injury can be difficult in newborn infants. Condition at birth does not predict neonatal, or longer term outcome. Biomarkers which could be measured at the time of birth and analysed at the bedside would offer these infants the best chance of timely and effective intervention. Through the BIHIVE study we have identified a number of predictive biomarkers in hypoxic-ischaemic encephalopathy. These markers are present in umbilical cord blood and have been identified through proteomic and metabolomic analysis of a stored biobank of samples from a recruited cohort of infants with perinatal asphyxia and hypoxic-ischaemic encephalopathy. We now wish to validate these biomarkers in an additional cohort, and will continue to explore new biomarkers in our stored biobank of umbilical cord samples. In addition we wish to assess our ability to predict neurodevelopmental and behavioural outcome in these infants. In this way we will determine the most robust biochemical and clinical markers for the prediction of early and medium term outcome in HIE. This study will establish the evidence base and validation of these biomarkers to the point where they can be developed into a bedside diagnostic algorithm which can be used in the labour ward to immediately identify those infants at risk of HIE in time to prevent secondary damage.
This study is to evaluate the safety and efficacy of Umbilical Cord Derived Mesenchymal Stem Cells transplantation in hypoxic ischemic encephalopathy.
To date, few studies have been done regarding nutrition supplementation in infants with brain injury. Therefore, the investigators are proposing to study the effects of protein supplementation in this group of babies. The investigators will recruit 24 infants with brain injury (evidence of hemorrhage, white matter injury, or gray matter injury) admitted to the Cincinnati Children's Hospital Neonatal Intensive Care Unit (NICU) into the study. Upon diagnosis, the investigators will obtain consent from the parents for participation in the study, then randomly assign the baby to one of two groups - an increased protein group and a control group. Both groups of infants will be monitored to ensure no adverse effects occur due to the supplementation. Protein supplementation will continue for the first 12 months of age. Growth parameters, such as weight, length, and head circumference, will be measured while the infant is the NICU. Head circumference will be measured in the investigators outpatient clinic at three, six, and 12 months of age. At 18-22 months, the infants will be tested for neurodevelopmental outcomes using the Bayley Scales of Infant Development. The investigators hypothesize that infants who receive the additional protein will demonstrate increased head growth and improved neurodevelopmental outcomes.
