An observational study in COVID and Acute Respiratory Distress Syndrome, sponsored by University Hospital, Angers. Status unknown at 1 site in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2020-04-10.
Sponsored by University Hospital, Angers · Observational
The actual pandemic infection related to SARS-CoV2 results in viral pneumonitis (COVID-19), that may, in the more severe cases, lead the patients to the intensive care unit (ICU). The more frequent presentation is acute respiratory distress syndrome (ARDS).
To penetrate cells, SARS-CoV2 uses Angioconvertase type 2 (ACE2) as a cellular entry receptor.
ACE2 belong to the renin-angiotensin-aldosteron system (SRAA), and ACE2 levels are directly modified when SRAA inhibitors are administred to patients, and ACE2 level increases particularely with Angiotensin II Receptor blockers (ARA2) use.
The aim of our study is to determine ACE2 level and activity in patients with SARSCoV2 infection admitted to the intensive care unit (ICU).
COVID ARA2 is a propsective cohort of patient with blood sampling at the day of admission, day 3 and day 7.

Participants :
Exclusion Criteria:
blood sampling at the day of admission, day 3 and day 7
ACE2 level change over time
ELISA test (Higher the ACE2 level, higher the virus penetrate cells)

Sequential Organ Failure Assessment (SOFA) score
The SOFA score evaluates the severity of patients through 6 items: respiration (PaO2/FiO2 ratio); coagulation (platelets count); liver (bilirubin); Cardiovascular (hypotension); Central nervous system (coma glasgow score) and Renal (creatinine serum level). Score ranges from 0 to 24, a higher score indicates higher severity and probability of death
