Dexamethasone and Oxygen Support Strategies in ICU Patients With Covid-19 Pneumonia (COVIDICUS)

2021年2月6日 更新者:Assistance Publique - Hôpitaux de Paris

Dexamethasone and Oxygen Support Strategies in ICU Patients With Covid-19 pneumonia_COVIDICUS

The main manifestation of COVID-19 is acute hypoxemic respiratory failure (AHRF). In patients with AHRF, the need for invasive mechanical ventilation is associated with high mortality.

Two hypotheses will be tested in this study. The first hypothesis is the benefit of corticosteroid therapy on severe COVID-19 infection admitted in ICU in terms of survival.

The second hypothesis is that, in the subset of patients free of mechanical ventilation at admission, either Continuous Positive Airway Pressure (CPAP) or High-Flow Nasal Oxygen (HFNO) allows to reduce intubation rate safely during COVID-19 related acute hypoxemic respiratory failure.

The main manifestation of COVID-19 is acute hypoxemic respiratory failure (AHRF). In patients with AHRF, the need for invasive mechanical ventilation is associated with high mortality.

Two hypotheses will be tested in this study. The first hypothesis is the benefit of corticosteroid therapy on severe COVID-19 infection admitted in ICU in terms of survival.

The second hypothesis is that, in the subset of patients free of mechanical ventilation at admission, either Continuous Positive Airway Pressure (CPAP) or High-Flow Nasal Oxygen (HFNO) allows to reduce intubation rate safely during COVID-19 related acute hypoxemic respiratory failure.

The main objective is to assess the impact of dexamethasone on overall mortality at day-60 after randomization in patients admitted in ICU for severe COVID-19 infection.

In non mechanical ventilation (MV) patients, the additional objective is to assess whether oxygen support based on either HFNO or CPAP modality in COVID-19 related AHRF reduces the need for mechanical ventilation at day-28.

An ancillary study CACAO (COVIDICUS air contamination) will be performed in 4 centers aiming at assessing the environmental contamination by SARS-CoV-2 according to the oxygen support modality. Additional funding will be searched for these analyses (submitted for ANR call).

A metanalysis on individual data will be performed using patients enrolled in the 3 PHRC flash exploring the activity of corticosteroids.
