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:
This is a prospective multicenter cohort of patients treated with the usual standard of care including systemic corticosteroid therapy with dexamethasone 6 mg / day.
INCLUSION (D0): The patients are examined on the day of their hospital admission. After an initial eligibility check and if interest is expressed by the patient, a specific inclusion visit is carried out.
FOLLOW-UP: Patients are clinically evaluated at least twice a day (Clinical examination, SpO2, vital signs) during hospitalization. Chest computed tomography and SARS-CoV-2 serology are performed on D0. Viral load is evaluated by the polymerase chain reaction which allowed the diagnosis of covid-19 in the 48 hours preceding D0 and on D7. The evaluation of conventional biomarkers of interest (blood count, hepatic assessment (ASAT, ALAT), serum creatinine, albuminemia, CRP, D-Dimers, LDH, Ferritin) are carried out on D0 (before the 1st dose of corticosteroids), D2 , J4 and J7. The evaluation of biomarkers of interest evaluated by mass spectrometry is carried out on D0 and D7 +/- 2 days.
A follow-up call on D28 is carried out (telephone call, collection of vital status and hospitalizations).

The general goal is to make the study data available to interested researchers as well as to provide proof of transparency for the study. Data (and an accompanying data dictionary) will be de-identified and potentially further cleaned or aggregated as the investigators deem necessary to protect participant anonymity.
Data will be made available to persons who address a reasonable request to the study director and fulfil the requirements stipulated by the French CNIL (Commission Nationale de l'Informatique et des Libertés : https://www.cnil.fr/professionnel).
Supporting documents will either be published or provided via the URL provided below (in real-time in as much as possible).
Datasets can be requested after the publication process has been completed.
The conditions under which members of the public will be granted access to datasets are:
