Brief Summary:

Perinatal hypoxic-ischaemic encephalopathy occurs in one to three infants per 1000 term births, and up to 12 000 infants are affected each year in the united state of America. Hypoxic ischemic encephalopathy is not preventable in most cases, and therapies are limited. Hypothermia improves outcomes and is the current standard of care. Yet clinical trials suggest that 44% to 53% of infants who receive hypothermia will die or suffer moderate to severe neurological disability. Therefore, novel neuroprotective therapies are urgently needed to further reduce the rate and severity of neurodevelopmental disabilities resulting from hypoxic ischemic encephalopathy.

Erythropoietin is a novel neuroprotective agent, with remarkable neuroprotective and neuroregenerative effects in animals. Rodent and primate models of neonatal brain injury support the safety and efficacy of multiple erythropoietin doses for improving histological and functional outcomes after hypoxia-ischaemia.

Hypoxic-Ischemic Encephalopathy Drug: Erythropoietin Drug: normal saline Phase 3

Detailed Description:

The cellular mechanisms by which erythropoietin exert neuroprotection are complex and not completely understood. In the acute period after hypoxia ischaemia, erythropoietin signaling in the brain induces several neuroprotective mechanisms. In addition to its anti-apoptotic and anti-inflammatory properties, erythropoietin also increases antioxidant activities and reduces excitotoxic cell injury.

In addition to its acute effects, erythropoietin stimulates growth factor release, enhances neurogenesis and angiogenesis, and promotes long-term repair and plasticity. Thus, erythropoietin provides neuroprotective and trophic effects that last well beyond the acute period of injury erythropoietin .enhances neurogenesis and directs multipotent neural stem cells to differentiate toward a neuronal cell fate.

In a clinical trial performed in China, Zhu et al. studied 167 neonates with of hypoxic ischemic encephalopathy that were randomized to receive erythropoietin (300-500U/kg) or placebo every second day for 2 weeks. The first dose of erythropoietin was given within 48 hours of delivery. Compared with placebo-treated infants, infants that received erythropoietin were less likely to die or have moderate to severe disability at 18 months of age (44% vs 25%, p=0.02).

Similarly, Elmahdy et al. studied 30 infants with hypoxic ischemic encephalopathy who were randomized to receive five daily doses of 2500 units/kg erythropoietin, or placebo, with the first dose given within 24 hours of delivery. The erythropoietin-treated infants demonstrated improved electroencephalography backgrounds, reduced biomarkers of oxidative stress after 2 weeks, and improved neurodevelopment at 6 months of age compared with placebo treated infants.

Arm Intervention/treatment
Experimental: study group
Within 4 to 6 hours after birth all cases with moderate to severe hypoxic ischemic encephalopathy will be enrolled in therapeutic hypothermia using total body cooling and temperature and Receive erythropoietin (1000 U/kg intravenously) on days 1, 2, 3, 5 ,7 and 9 (six doses,first two doses will be daily from the first day and last 4 doses will be every 2 days)
Drug: Erythropoietin

Placebo Comparator: control group
Within 4 to 6 hours after birth cases with moderate to severe hypoxic ischemic encephalopathy enrolled in therapeutic hypothermia using total body cooling and temperature and Receive normal saline on days 1, 2, 3, 5 ,7 and 9 (six doses,first two doses will be daily from the first day and last 4 doses will be every 2 days)
Drug: normal saline

Primary Outcome Measures :
  1. Death or long-term major neurodevelopmental disability according to Griffith score. [ Time Frame: 12 month ]
    The score is reported as normal if the score is between 85 and 114, mildly delayed if the score is 1 Stander deviation below the mean (<85), and significantly delayed if the score is 2 Stander deviation below the mean (<70)

Secondary Outcome Measures :
  1. cerebral palsy [ Time Frame: 12 month ]
    Presence and type of cerebral palsy determined using a standardized neurologic examination: no cerebral palsy,diplegic cerebral palsy,hemiplegic cerebral palsy, quadriplegic cerebral palsy.

  2. Epilepsy. [ Time Frame: 12 month age. ]
    define as 2 or more afebrile unprovoked seizure.

  3. Magnetic resonance image evidence of brain injury. [ Time Frame: 2-3 weeks after birth. ]
    The magnetic resonant imaging global scores will range from 48 to 186. score at 48 showing no evidence of acute injury; injury considers mild if the global score will between 49and 59, moderate if between 60 and 80 and severe if more than 81.

  4. Electroencephalogram evidence of brain injury. [ Time Frame: 1 weeks after birth ]
    EEG will be graded in to normal ,mild ,severe and isoelectric using EEG score according to Murray et al 2009

  5. Adverse effect of erythropoietin [ Time Frame: 12 months ]
    A-Hypertension: a systolic blood pressure in a neonate which is above 95th percentile for age and sex on three separate occasions; B- thrombotic events; C-polycythemia: central venous hematocrit of greater than 65%. D- red cell aplasia secondary to antierythropoietic antibodies. OR any other adverse effect appear during hospital stay or follow up.

  6. seizure [ Time Frame: during 2 weeks after birth ]
    number of clinical and electroencephalogram seizure
