About

To date, there is no efficient therapeutics to prevent or treat COVID-19 related pulmonary failure. Corticosteroids (CS) could be a helpful therapeutic. Retrospective reports suggested survival improvement in patients with acute respiratory distress syndrome (ARDS). CT scan for COVID19 hospitalized patients showed sometimes unusual aspects of pneumonia, suggestive of an organizing phase of diffuse alveolar damage (DAD).

We hypothesize that, in the context of alveolar aggression induced by COVID-19, CT scan could help to individualize patients with a high probability of pulmonary organizing process who could benefit from CS treatment.

Full description

"Severe acute respiratory syndrome" coronavirus 2 (SARS-Cov-2) is a new coronavirus that induces pneumonia called Corona Virus Disease- 19 (COVID-19), an infected 1.5 million people worldwide and caused the more than 85,000 patients died. COVID-19 usually comes in the form of viral pneumonia but with the peculiarities of a risk frequent worsening towards acute respiratory distress syndrome (ARDS) and a usual duration of oxygen dependence in fragile patients by their age or their comorbidities. To date, there is no therapy effective in preventing or treating COVID-19. Drug identification is a major concern and a public health emergency. Retrospective study (Wu 2020) highlighted improved survival in COVID-19 patients with acute ARDS and treated with corticosteroids (CS). So even in the absence of evidence of effectiveness, the SCs are used for COVID-19 oxygen-dependent patients or with an ARDS. However, their benefit / risk remains debated (Russel 2020). On histological samples of COVID-19, diffuse alveolar damage (DAD) has been especially observed (Hanley 2020). DAD is described histologically in an exudative phase, an organizational phase and a irreversible fibrotic phase (Hughes 2017). SC could have an effect beneficial by limiting the exudative / inflammatory phase but also that organization whose histological and CT aspects are sometimes indistinguishable from organized pneumonia, a form of pulmonary repair aberrant very corticosensitive (Travis 2013). Chest scans performed in the face of the persistence or worsening of oxygen dependence beyond the 7th day of COVID-19 symptoms, could help discern indirect complications (pulmonary embolism, exacerbation of COPD, bacterial superinfection, etc.) of an unfavorable course COVID-19 (by displaying an aspect suggesting DAD in particular during the organization phase). We hypothesize that, in the context of COVID-19, the SCs may be beneficial in patients with CT scans thoracic images suggestive of DAD either at the exudative phase or at the pulmonary organization phase.
