View clinical trials related to Neonatal Encephalopathy.
Filter by:Hypoxic-ischemic encephalopathy (HIE) occurs when a baby gets reduced blood flow and oxygen to the brain near the time of birth. This results in death or neurologic disabilities including cerebral palsy and cognitive impairment in up to half of affected infants. This clinical trial will determine if the drug erythropoietin (Epo) added to hypothermia (usual therapy) will improve outcomes for infants suffering from HIE.
Neonatal Encephalopathy is a serious condition arising from unexpected lack of cerebral blood flow and oxygen supply to the foetal brain at the time of birth. Every year, approximately one million babies die from neonatal encephalopathy in low and middle-income countries and a quarter of these deaths occur in India. In the past decade, a number of clinical trials in high-income countries has shown that cooling therapy along with optimal neonatal intensive care reduces death and neurodisability after neonatal encephalopathy. Cooling therapy is now used as a standard therapy after neonatal encephalopathy in all high income countries, including the UK. Although the burden of neonatal encephalopathy is far higher in low and middle-income countries, the safety and efficacy data on cooling therapy from high income cooling trials cannot be extrapolated to these settings, due to the difference in population co-morbidities and sub-optimal neonatal intensive care. The HELIX trial proposes to examine whether whole body cooling to 33.5°C initiated within 6 hours of birth and continued for 72 hours reduces death or neurodisability at 18 months after neonatal encephalopathy in public sector neonatal units in India. A total of 408 babies with moderate or severe neonatal encephalopathy will be recruited from the participating centres in India over an 18 to 24 month period. The babies will be randomly allocated to whole body cooling or usual care. The cooling therapy will be achieved using an approved cooling device (Tecotherm) that is already in clinical use in the UK and in India. MR imaging and spectroscopy will be performed at 1 week of age to examine the brain injury. Neurodevelopmental outcomes will be assessed at 18 months of age. Primary outcome measure is death or moderate/severe neurodisability at 18 months.
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), a condition of reduced blood and oxygen flow to a baby's brain near the time of birth, may cause death or neurologic disability. Cooling therapy (hypothermia) provides some protection, but about half of affected infants still have a poor outcome. This clinical trial will determine if the drug erythropoietin, given with hypothermia, is safe to use as a treatment that may further reduce the risk of neurologic deficits after HIE.
Whole body cooling improves survival with normal neurological outcome after neonatal encephalopathy in high-income countries. However, cooling equipments used in the high-income countries are expensive and unsuitable for wider use in low and middle-income countries (LMIC). We had previously conducted a randomised controlled trial of whole body cooling using phase changing material in south India. Although cooling was provided, there were wide temperature fluctuations. Aim: To examine efficacy of the low technology cooling equipment (Tecotherm-HELIX) in administering effective and stable whole body cooling in encephalopathic infants. Methods: After informed parental consent (and ethical approvals), we will administer 72 hours of whole body cooling (rectal temperature 33 to 34C) to a total 50 encephalopathic infants (aged <6 hours) admitted to the neonatal units at Calicut Medical College and Madras Medical College, over a six month period. To induce cooling, the infants will be kept on the cooling mattress. Temperature will be continuously measured for 80 hours using a rectal probe connected to a digital data logger. The primary outcome will be the effective cooling time i.e. percentage of time (95% CI) for which the temperature remains between 33 to 340C during the intended cooling period.
N-acetylaspartate (NAA) is a surrogate neuronal marker and its proton magnetic resonance spectroscopy (1H MRS) signal decreases with increasing neuronal mortality associated with cerebral hypoxia-ischaemia. The MRS lactate (Lac)/NAA peak-area ratio increases during and after severe cerebral hypoxia-ischaemia reflecting mitochondrial injury and impaired oxidative phosphorylation. Aims: (1) To establish normative ranges for thalamic 1H MRS NAA concentration and Lac/NAA in healthy newborn infants (2) To examine the accuracies of thalamic 1H MRS NAA concentration and Lac/NAA for predicting adverse neurodevelopmental outcome in neonatal encephalopathy (NE) Design: Prospective observational study Methods: Year 1: Following 1H MRS methodology optimisation 40 healthy control infants will be recruited to collect normative data. Year 2 to 3: 115 infants with NE, undergoing therapeutic hypothermia will be recruited. MRS will be performed aged less than 4 days and 7 to 14 days and thalamic NAA levels and Lac/NAA will be quantified; Qualitative interviews to evaluate parental understanding of this biomarker. Year 4, 5: Outcome assessment by BSID III at 18 months. Outcomes: Mean thalamic NAA levels and Lac/NAA and appropriate confidence intervals in normal infants, and thalamic NAA levels and Lac/NAA in infants with NE according to neurodevelopmental outcome. Areas under curves for thalamic NAA and Lac/NAA will be examined separately for early & late MRS. Accuracy of early MRS will inform utility of this investigation in decisions about withdrawal of life support; late MRS will inform about efficacy as a surrogate end point in clinical trials. Qualitative interviews will be thematically analysed and reported.
This observational study will assess long-term functional outcome of survivors from neonatal encephalopathy who were previously treated with either head cooling or with conventional care in a randomized clinical trial. Children's parents will be interviewed by phone by trained staff using the WeeFIM questionnaire to ascertain the childrens' functional performance on a set of skills basic to daily life. This instrument is able to assess a very wide range of abilities, from independently functioning to needing total assistance. The ratings will be used to examine the relationship between the outcome previously measured at 18 months age and functional outcome at school age and to triage the children into those who clearly could not be tested on standardized exams of cognitive functioning, those who potentially could, even if at a low level of cognitive ability, and those who appear to be functioning at an age-appropriate level.
