FERNANDEZ CUADROS, ME et al. Ozone and COVID-19: physiological bases and their therapeutic possibilities according to the evolutionary stage in SARS-CoV-2 infection. Rev. Soc. Esp. Dolor [online]. 2021, vol.28, n.1, pp.27-36.  Epub 29-Mar-2021. ISSN 1134-8046.  https://dx.doi.org/10.20986/resed.2021.3810/2020.

To date, there is no definitive treatment for the new SARS-CoV-2 pandemic. Three evolutionary stages are recognized in SARS-CoV-2 infection (early infection, pulmonary phase and systemic hyperinflammation), with characteristic clinical signs and symptoms. There are 80 international experimental trials underway seeking an effective treatment for the COVID-19 pandemic. Of them, there are only 3 that consider to Ozone Therapy as an alternative (major auto hemotherapy). There is no study that evaluates Rectal Ozone Insufflation, despite being a safe, cheap, risk-free technique and that it is a systemic administration route (Oxygen-Ozone 95 %-5 %) and that justifies conducting clinical trials to validate the theoretical properties of Ozone in the management of SARS-CoV-2, given the excellent results observed in the management of ebola.

Ozone has 4 proven biological properties that could be of potential theoretical utility as a complementary therapy in the different phases of SARS-CoV-2 infection. Ozone could inactivate the virus by indirect oxidation (ROS and LOP) and could stimulate the cellular and humoral immune system, being useful in the early infection phase (stages 1 and 2a). Ozone can improve gas exchange, reduce inflammation, and modulate the antioxidant system, so it would be useful in the hyperinflammation or cytokine storm phase, and in the hypoxemia and / or multi-organ failure phase (stages 2b and stage 3).

Given the current pandemic, it is urgent to carry out an experimental study to confirm or rule out the biological properties of Ozone and thus allow it to be a complementary or compassionate therapy for the effective management of SARS-CoV-2 infection.
