简要总结
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
- Length of hospitalization
- The change in the extent of lesions on thoracic computed tomography scan between inclusion and D7 (or the day of discharge from hospital if <D7)
- Change in biomarkers on D0, D2, D4, D7 (NFS, liver tests (ASAT, ALAT), Creatinine, Albumin, CRP, D-dimers, Ferritin, LDH, lymphocyte phenotyping)
- Demonstrate other biomarkers of interest from the usual management (NFS, liver function tests (ASAT, ALAT), Creatinine, Albumin, CRP, D-dimers, Ferritin, LDH, lymphocyte phenotyping)
- Change in biomarkers evaluated by mass spectrometry (on a blood sample) on D0 and D7 +/- 2 days
- The initial viral load (within 48 hours preceding D0) and at D7 of inclusion estimated from the nasopharyngeal SARS-CoV-2 RT-PCR
- Initial SARS-CoV-2 serology and on D7 from inclusion
- The A38G polymorphism of the gene coding for Club Cell Secretory Protein (CCSP) for each patient
- Short-term complications related to corticosteroid therapy
- The quantitative and qualitative impact of corticosteroid therapy on lymphocytes from patients with COVID-19.
详细描述
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).
