Brief Summary:
The SARS-CoV2 virus causes severe or even fatal disease in a fraction of infected people. The clinical severity is based on a complicated pneumopathy with acute respiratory distress syndrome that can lead to multi-visceral failure. The underlying mechanism is a cytokinergic storm, an emerging facet of immunological dysregulation.
This clinical trial is aimed to understand the mechanisms of this immunological dysregulation in order to identify therapeutic levers.
The main objective is to understand the relationships between clinical severity, death or morbidity of resuscitation management, and immune status (i.e., immune pathways activated or not). Immune status will be investigated at many levels of organization (i.e., circulating leukocytes, cytokines and chemokines, transcripts).
The secondary objectives are :
* to understand what is responsible for clinical severity, viral load, or immune activation;
* to highlight the consequences of immunological dysregulation on associated risks (i.e., immunosuppression leading to the emergence of infectious comorbidities) as well as the functioning of neurotransmission through metabolic pathway diversions. The impact of dysimmunity on these biological pathways will be assessed with a metabolomic analysis;
* to understand the mechanisms of vulnerability related to the field. Moreover, while co-morbidities are likely to be a risk factor for severe disease progression, there are many situations in which they do not occur. Stress, with its neurovegetative and endocrinological dimensions, modulates the immune response. It is essential to know whether the stress response plays a role in immunological dysregulation. This analysis is a prerequisite for understanding the conditions of treatment with glucocorticoids.
Angiotensin converting enzyme type 2 (ACE2) also plays a likely role in host viral infection. It is also thought to play an important role in the emergence of severe syndromes by affecting the quality of vascular response.
