Perinatal asphyxia-induced brain injury is one of the most common causes of morbidity and mortality in term and preterm neonates, accounting for 23% of neonatal deaths globally. Although many neuroprotective strategies appeared promising in animal models, most of them have failed clinically. Erythropoietin (EPO) is an endogenous cytokine originally identified for its role in erythropoiesis. Clinical trial has demonstrated the safety and efficacy of recombinant human erythropoietin (r-hu-EPO) in the prevention or treatment of anemia of prematurity. To date, there are no reports evaluating possible effects of EPO on neonatal HIE.
Hypoxic-ischemic encephalopathy of the newborn infant remains a significant socio-economic health problem worldwide. Moderate to severe HIE of newborn infants is associated with a high rate of death or long-term disabilities. Historically, treatment has been purely supportive including stabilizing cardio-respiratory functions and treating convulsions.Recent multi-center trials assessing the effects of hypothermia demonstrated improved outcome in term neonates with moderate hypoxic-ischemic encephalopathy (HIE). However, hypothermia was not effective beyond 6 hrs after brain injury.
Systemically administered EPO was neuroprotective in neonatal brain injury models. Clinical study on adult stroke showed improved outcome. However, treating HIE with EPO raises a series of questions such as: i) Can the patient population of this study readily be compared with those in the hypothermia trials? ii) What are the pharmacokinetics of EPO, including issues of dosage and timing, and does administered EPO cross the blood-brain-barrier? iii) How does the effectiveness, side effects and potentials of EPO therapy compare with induced hypothermia?

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 ...

This study is a randomized, placebo-controlled, clinical trial to evaluate whether induced whole-body hypothermia initiated between 6-24 hours of age and continued for 96 hours in infants ...
To determine if multiple doses of erythropoietin (Epo) administered with hypothermia improve neuroradiographic and short-term outcomes of newborns with hypoxic-ischemic encephalopathy.
To identify perinatal risk factors that can distinguish arterial ischemic stroke from hypoxic-ischemic encephalopathy at birth.
Perinatal management and prognostic value of clinical evaluation and diagnostic tools have changed with the generalization of therapeutic hypothermia (TH) in infants with hypoxic-ischemic encephalopat...
The vulnerable brain areas in hypoxic-ischemic encephalopathy (HIE) following systemic hypotension are typically the neocortex, deep cerebral gray nuclei, hippocampus, cerebellum, and the parieto-occi...
Hypoxic-ischemic encephalopathy is a condition caused by reduced oxygen and cerebral blood flow to the brain resulting in neurological impairments. Effective therapeutic treatments to ameliorate these...
This recombinant erythropoietin, a 165-amino acid glycoprotein (about 62% protein and 38% carbohydrate), regulates red blood cell production. Epoetin alfa is produced by Chinese hamster ovary cells into which the human erythropoietin gene has been inserted. (USP Dictionary of USAN and International Drug Names, 1996).
The application of repeated, brief periods of vascular occlusion at the onset of REPERFUSION to reduce REPERFUSION INJURY that follows a prolonged ischemic event. The techniques are similar to ISCHEMIC PRECONDITIONING but the time of application is after the ischemic event instead of before.
Cell surface proteins that bind erythropoietin with high affinity and trigger intracellular changes influencing the behavior of cells.
A nitroimidazole that sensitizes normally radio-resistant hypoxic cells to radiation. It may also be directly cytotoxic to hypoxic cells and has been proposed as an antineoplastic.
A clinically diverse group of epilepsy syndromes characterized either by myoclonic seizures or by myoclonus in association with other seizure types. Myoclonic epilepsy syndromes are divided into three subtypes based on etiology: familial, cryptogenic, and symptomatic (i.e., occurring secondary to known disease processes such as infections, hypoxic-ischemic injuries, trauma, etc.).
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
