Hyperbaric oxygen therapy may cause DNA damage, raising concerns about safety. Research suggests modified treatments can prevent these genotoxic effects, enhancing therapeutic safety.

Area of Science:

  • Biomedical Engineering
  • Molecular Biology
  • Medical Physiology

Background:

  • Hyperbaric oxygen (HBO) therapy treats oxygen-deprived tissues but carries risks of oxidative stress and cell damage.
  • Concerns exist regarding oxygen toxicity and potential cancer-promoting effects of HBO.
  • Recent studies show HBO can induce oxidative DNA damage in blood cells, necessitating further investigation.

Purpose of the Study:

  • To review studies investigating the biological significance of HBO-induced oxidative DNA damage.
  • To critically discuss potential adverse genetic effects of HBO therapy.
  • To propose a modified HBO treatment regimen to mitigate genotoxic effects.

Main Methods:

  • In vitro and in vivo experimental tests were conducted.

  • Review of existing literature on HBO therapy and its genetic effects.
  • Analysis of anti-oxidative defense mechanisms post-HBO exposure.

    • Main Results:

    • HBO therapy can induce oxidative DNA damage in blood cells.
    • The biological significance of this damage was explored through various tests.
    • HBO exposure was found to induce anti-oxidative defense mechanisms.

    Conclusions:

    • HBO therapy poses a risk of oxidative DNA damage.
    • A modified HBO treatment regimen is proposed to avoid genotoxic effects.
    • Further research is needed to optimize HBO therapy for safety and efficacy.
