The primary objective of this study is to demonstrate (at the time of admission) biomarkers
      of interest (Human Plasma BAK125 panel + interferon panel) for dexamethasone responders
      versus non-responders in SARS-CoV-2 hypoxemic pneumonia.
      The secondary objectives are to describe and compare between groups:
        -  The number of days without mechanical ventilation
        -  The need for mechanical ventilation
        -  28-day mortality
        -  Progression towards acute respiratory distress syndrome (ARDS)
        -  Change in the qSOFA score

Description: Capillary glycemia will be measured at least twice per day throughout the initial hospitalization period. Description: The Quick Sequential Organ Failure Assessment (qSOFA) score will be assessed at least twice per day throughout the initial hospitalization period.
The quick Sepsis-related organ failure assessment (qSOFA) score ranges from 0 to 3 points, with '3' indicating the worst health state. It uses three criteria, assigning one point for low blood pressure (systolic blood pressure ≤100 mmHg), high respiratory rate (≥22 breaths per min), or altered mentation.
