Abstract

Birth asphyxia and its main sequel, hypoxic-ischemic encephalopathy, are one of the leading causes of children's deaths worldwide and can potentially worsen the quality of life in subsequent years. Despite extensive research efforts, efficient therapy against the consequences of hypoxia-ischemia occurring in the perinatal period of life is still lacking. The use of hyperbaric oxygen, improving such vital consequences of birth asphyxia as lowered partial oxygen pressure in tissue, apoptosis of neuronal cells, and impaired angiogenesis, is a promising approach. This review focused on the selected aspects of mainly experimental hyperbaric oxygen therapy. The therapeutic window for the treatment of perinatal asphyxia is very narrow, but administering hyperbaric oxygen within those days improves outcomes. Several miRNAs (e.g., mir-107) mediate the therapeutic effect of hyperbaric oxygen by modulating the Wnt pathway, inhibiting apoptosis, increasing angiogenesis, or inducing neural stem cells. Combining hyperbaric oxygen therapy with drugs, such as memantine or ephedrine, produced promising results. A separate aspect is the use of preconditioning with hyperbaric oxygen. Overall, preliminary clinical trials with hyperbaric oxygen therapy used in perinatal asphyxia give auspicious results.

The schematic diagram showing the impact of hyperbaric oxygen therapy on the deleterious effect of hypoxia-ischemia (HI) on the brain. HI induces energy deficiency, apoptosis, necrosis, and loss of brain functions. On the other hand, hyperbaric oxygen, supplied in an appropriate therapeutic window, restores normal cellular functioning, significantly reducing brain injury. Both processes exert their activities through miRNAs and lncRNAs.

The figure presents all miRNAs identified, and division into groups depending on their up-or down-regulation in analyzed conditions.
