  1. Hyperbaric Oxygen for COVID-19 Patients: NCT0433208 (Recruiting) • HBO2 protocol as below • (HBO2 2.0 ATA 1-5 treatments)

Sponsors and Collaborators: NYU Langone Health; NYU Winthrop Hospital Information provided by (Responsible Party): NYU Langone Health

STUDY DESCRIPTION Brief Summary: Hyperbaric oxygen (HBO2) therapy treatment will be provided to patients as an adjunct to standard therapy for a cohort of 40 COVID19-positive patients with respiratory distress at NYU Winthrop Hospital. All patients prior to the clinical application of HBO2 will be evaluated by the primary care team and hyperbaric physician. After the intervention portion of this study a chart review will be performed to compare the outcomes of intervention patients versus patients who received standard of care.

Detailed Description: This is a single-center prospective pilot cohort study to evaluate the safety and efficacy of hyperbaric oxygen (HBO2) therapy as an emergency investigational device for treating patients with a novel coronavirus disease, COVID-19. Patients who meet inclusion criteria will be consented by the hyperbaric physician. They will then be transported from the ED or other unit to the hyperbaric unit while maintaining airborne precautions based on the most current hospital protocol. All study personnel will have proper PPE at all times. The patient will then be placed into the monoplace chamber and when the chamber door is closed the patient will remove any respiratory filter/mask that was placed. The patient will receive 90 minutes of hyperbaric oxygen at 2.0 ATA with or without air breaks per the hyperbaric physician. Upon completion of the treatment the patient will then return to the medical unit and continue all standard of care. Additional treatments (up to 5) can be given if warranted and agreed upon by the patient and all members of the team caring for the patient. After the intervention portion of this study a chart review will be performed to compare the outcomes of intervention patients versus patients who received standard of care.

Management by Hyperbaric Oxygen Therapy of Patients With Hypoxaemic Pneumonia With COVID-19: NCT04344431 (Recruiting)

Sponsor: Direction Centrale du Service de Santé des Armées

STUDY DESCRIPTION

Brief Summary: Several patients with hypoxaemic SARS-CoV-2 pneumonia were able to benefit from hyperbaric oxygen (HBO2) treatment in China. In a clinical case published in the Chinese Journal of Hyperbaric Medicine, treatment with repeated HBO2 sessions prevented admission to intensive care unit with mechanical ventilation in a patient aged 69 who presented with signs of respiratory decompensation. HBO2 can dramatically increase the amount of dissolved oxygen in the blood. HBO2 not only promotes blood transport but also its tissue delivery. Furthermore, HBO2 has specific immunomodulatory properties, both humoral and cellular, making it possible, for example, to reduce the intensity of the inflammatory response and to stimulate antioxidant defenses by repeating sessions. A virucidal capacity of HBO2 therapy might also be involved.

Detailed Description: The main objective of this study is to assess the effectiveness of HBO2 in addition to normal management over the period of normalization of the oxygen requirement (oxygen dependence) in patients with SAR-CoV-2 pneumonia not requiring invasive or non-invasive ventilation. It is a prospective, interventional, multicenter, controlled, randomized study. Patients admitted for SARS-CoV2 pneumonia in the COVID sector of the hospital who have oxygen-dependence criteria will be proposed for inclusion in accordance with the inclusion and non-inclusion criteria. Randomization will be carried out to determine the allocation in two groups: an HBO2 group which will perform a daily session after checking for the absence of contraindication to HBO2 and a non-HBO2 control group with the same clinical criteri, but who will not benefit from HBO2 sessions. In both groups standard continuous treatment with normobaric oxygen will be maintained.

  1. Safety and Efficacy of Hyperbaric Oxygen for ARDS in Patients With COVID-19

(HBO2 protocol 2.4 bar (2.4 ATA), 30 minutes (excluding compression/recompression-maximum 5 treatments over 7 days)

Karolinska University Hospital

Collaborators: Karolinska Institutet; University of California San Diego; Blekinge County Council Hospital

STUDY DESCRIPTION

Brief Summary: Mortality rates in patients who develop ARDS is extremely high, 61.5-90%, almost double the mortality of ARDS of any cause. ARDS associated with COVID-19 is associated with pulmonary edema, rapidly progressing respiratory failure and fibrosis. The mechanism behind the rapid progress is still an enigma, but theories have evolved around severe inflammatory involvement with a cytokine storm. HBO2 significantly reduces inflammatory cytokines and edema.

Detailed Description:

Mortality rates have been reported as high as 90% in patients developing ARDS in early reports and more recent reports have reported overall 28-day mortality rates of 61.5% in ICU patients with acute respiratory illness. ARDS associated with COVID-19 differs from other ARDS, with rapidly progressing respiratory failure and fibrosis. Macrophage activation is involved early and cytokine modulators such as interleukin-6 (IL-6) inhibitors have been tried in experimental settings but no proper clinical trials have proven positive outcome. Hyperbaric oxygen (HBO2) significantly reduces inflammatory cytokines including IL-1β, IL-6 and TNF-α through several transcription factors regulating inflammation, including hypoxia inducible factor 1 (HIF-1), Nrf2 and NFkB.

Sponsor: Assaf-Harofeh Medical Center Information provided by (Responsible Party): Assaf-Harofeh Medical Center

STUDY DESCRIPTION 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 (HBO2) therapy on 5 severe COVID-19 patients who developed respiratory insufficiency. HBO2 mechanisms of tissue oxygenation and anti-inflammatory effect may explain these findings. The purpose of the current study is the evaluate the efficacy of HBO2 therapy in moderate-severe COVID-19 patients in a randomized controlled manner.
