Clinical Trial 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.


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.

Outcome

Type Measure Description Time frame Safety issue
Primary abnormal short-term outcome (NE) 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.
14 days for clinical diagnosis
