简要总结

The 2019-20 coronavirus disease, caused by COVID-19, is an ongoing pandemic.So far, no specific treatment has proven efficacy. Recent case series reported the use of Hyperbaric Oxygen Therapy (HBOT) on 5 severe COVID-19 patients who developed respiratory insufficiency. HBOT mechanisms of tissue oxygenation and anti-inflammatory effect may explain these findings.

The purpose of the current study is the evaluate the efficacy of HBOT in moderate-severe COVID-19 patients in a randomized controlled manner.

详细描述

The 2019-20 coronavirus disease, caused by COVID-19, is an ongoing pandemic. The outbreak started in Wuhan, Hubei province, China, in December 2019 and the World Health Organization (WHO) recognized it as a pandemic on 11 March 2020. Up to Apr 9. 2020 there are more than 2 million confirmed cases, and over 140,000 deaths. In Israel, COVID-19 was confirmed in more 12,000 cases and took the life of 140 victims. There are 323 mild admitted cases, 170 moderate admitted cases and 170 severe admitted cases (16.04.2020) .

Even though the general mortality rate is low (0.2-7%, country based), patients who develop Acute Respiratory Distress Syndrome (ARDS) have a significantly higher mortality rate, up to 61-90%. COVID-19 ARDS is different, causing a rapidly progressive disease including respiratory insufficiency and pulmonary fibrosis. The mechanism behind isn't clear yet, but evidence points to the direction of an acute cytokines storm which include: IL-2, IL-7, GCSF, InterferonGamma, TNF-alpha, Macrophage chemoattractant protein . Poor prognosis include high levels of IL-6 and Ferritin.

More than 160 clinical trials have been registered, but as of April 2020, there is no proven effective treatment.

The use of hyperbaric oxygen therapy (HBOT) includes breathing 100% oxygen in pressures higher than 1 absolute atmospheres (ATA), increasing the amount of oxygen dissolved in the plasma and the different tissues. In the last month, Chen et al. reported a case series of 5 severe COVID-19 patients treated with 3-8 HBOT sessions in addition to the standard therapy. In all cases, they reported an increase in oxygen saturation, arterial oxygen content,lactate levels reduction,fibrinogen levels decrease and increase in lymphocytes number.In addition, the patients chest CT showed improved signs. Symptomatic relief started following the 2nd session. No significant adverse events were reported.

These findings may be explained by the known physiological effects of HBOT, related to the SARS-CoV-2 virus pathogenesis:
