Insights
Preterm infants are vulnerable to oxidative stress, leading to health issues. This study explores non-invasive methods to monitor oxidative stress biomarkers, improving infant care and outcomes.
Area of Science:
- Neonatal Medicine
- Biochemistry
- Pediatric Research
Background:
- Preterm newborns possess an immature antioxidant defense, increasing susceptibility to oxidative stress.
- Oxygen supplementation during neonatal intensive care unit (NICU) stays can exacerbate oxidative stress.
- Oxidative damage in preterm infants correlates with increased morbidities, neurodevelopmental issues, and mortality.
Purpose of the Study:
- To review studies utilizing non-invasive samples for oxidative stress biomarker determination in preterm infants.
- To identify methods for closer monitoring of preterm infants with greater predictive value.
- To present a validated high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) method for non-invasive biomarker analysis.
Main Methods:
- Literature review of studies employing non-invasive sampling techniques for oxidative stress biomarkers.
- Description of a validated HPLC-MS/MS method for analyzing biomarkers in biofluids.
- Focus on non-invasive and painless sample collection methods.
Main Results:
- Non-invasive sample analysis for oxidative stress biomarkers is feasible in preterm infants.
- Certain non-invasive methods show significant predictive value for monitoring infant health.
- The described HPLC-MS/MS method accurately quantifies reliable biomarkers in easily obtained samples.
Conclusions:
- Non-invasive monitoring of oxidative stress biomarkers can reduce the need for invasive procedures in the NICU.
- This approach facilitates closer monitoring and potentially improves outcomes for preterm infants.
- Validated non-invasive methods, like HPLC-MS/MS, offer a promising alternative for assessing oxidative stress in vulnerable newborns.
Abstract:
Preterm newborns have an immature antioxidant defense system and are especially susceptible to oxidative stress. Resuscitation, mechanical ventilation, intermittent hypoxia and apneic episodes require frequently oxygen supplementation which leads to oxidative stress in preterm newborns. The consequences of oxidative damage are increased short and long-term morbidities, neurodevelopmental impairment and increased mortality. Oxidative stress biomarkers are determined in blood samples from preterm children during their stay in neonatal intensive care units especially for research purposes. However, there is a tendency towards reducing invasive and painful techniques in the NICU (Neonatal Intensive Care Unit) and avoiding excessive blood extractions procedures. In this paper, it has been described some studies that employed non-invasive samples to determine oxidative stress biomarkers form preterm infants in order to perform a close monitoring biomarker with a significant greater predictive value. Among these methods we describe a previously developed and validated high-performance liquid chromatography tandem mass spectrometry method that allow to accurately determine the most reliable biomarkers in biofluids, which are non-invasively and painlessly obtained.

Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...
