Brief Summary

During their activation in response to an infectious stimulus or during chronic inflammatory processes, blood and tissue neutrophils modify their functional phenotype and produce numerous toxic mediators. In particular, they rapidly release chromatin filaments covered with numerous granular and cytoplasmic components called "Neutrophil Extracellular Traps" (NETs). This phenomenon, called netosis, has been implicated in many diseases, in particular in viral infections during which this response can be useful for the anti-infectious response at the initial phase, then deleterious when it becomes toxic. for the tissue environment. This has been shown in particular during post-pneumonia acute respiratory distress syndrome. The intensity of netosis is therefore an early factor in activating neutrophils and inflammation. Given the major biological signs of inflammation observed in patients with COVID-19 as soon as they enter the hospital \[C-Reactive protein (CRP), Interleukin-6 (IL-6), D-dimers, etc.), it seems particularly interesting to better document this inflammation.

Outcome Measures

Primary Outcomes (1)

  • Evaluation of the netosis process

    This outcome corresponds to the of the determination of DNA-myeloperoxidase complexes (DNA-MPO).

    Day 1

Secondary Outcomes (2)

  • Evaluation of the netosis process at day 3

    Day 3

  • Link between this marker (DNA-MPO) and the clinical course of patients

    Day 3

Study Arms (1)

Patients with COVID-19 infection

As part of this research, existing clinical data of patients infected with COVID-19 is collected from the patients' computerized medical records. During the hospitalization of the patients, in addition to the clinical and laboratory data collected, the dosage of IL-6, apparently playing a central role in the worsening of the symptoms of COVID-19, was performed. The remainder of the contents of the tube used to perform this assay will allow further research by assaying the DNA-myeloperoxidase (DNA-MPO) complexes. These complexes reflect a phenomenon called "netosis," most likely involved in the widespread inflammation that patients have suffered from.
