Brief Summary:
Verification of biomarkers in a human population for their ability to diagnose the severity of neonatal asphyxia. These biomarkers linked to asphyxia have been identified in animal studies.

Condition or disease Intervention/treatment
Asphyxia Neonatorum Other: blood sampling

Detailed Description:

The aim of the study is to verify the application of combinations of several laboratory parameters in early postnatal blood samples, for identification of infants, who will suffer from early abnormal neonatal neurological outcome, in a population at risk.

The population at risk is defined as term and late preterm (>36 weeks of gestation) human infants following perinatal hypoxia-ischemia with or without postnatal resuscitation.

Group/Cohort Intervention/treatment
Group 1
patients with hypoxic-ischemic encephalopathy (HIE) receiving hypothermia therapy
Other: blood sampling
small volume blood sampling, according to local laws, is not categorized as intervention (observational study)

Group 2
patients with suspected HIE, non-confirmed
Other: blood sampling
small volume blood sampling, according to local laws, is not categorized as intervention (observational study)

Group 3
healthy, retrospectively classified as such
Other: blood sampling
small volume blood sampling, according to local laws, is not categorized as intervention (observational study)

Primary Outcome Measures :
  1. abnormal short-term outcome (NE) [ Time Frame: 14 days for clinical diagnosis ]

    All patients are classified as abnormal short-term outcome (neonatal encephalopathy, NE) or normal short term outcome (no encephalopathy) by using clinical data, particularly Thompson score. For Group 1 and group 2 patients outcome classification will be additionally confirmed by using cranial ultrasound or MRI (including severe ischemia based on DWI or thalamic or cerebellar bleeding or arterial infarction or IVH>2° according to Papile, thalamic ischemia or severe cerebral edema) or seizure activity or burst suppression on aEEG or persistingly abnormal aEEG background pattern after complete rewarming.

    Bloodplasma samples will be analysed by a metabolomics approach using the p180-kit (Biocrates, Innsbruck, Austria). Metabolite concentrations or combinations thereof will be compared to the outcome described above in order to identify the most suitable metabolites to be used for early detection of NE in newborn infants.
