NCT04346017

Brief Summary

In patients infected by the SARS-Cov-2 Coronavirus a severely progressive disease requiring hospitalization in intensive care seems related to deregulation of cytokines with very high levels of IL-6, IL-2, IL-7, IL-10 and TNF-α. In order to elucidate the mechanism of this hyper inflammatory syndrome we will measure a panel of pro and anti inflammatory cytokines, as well as known markers of macrophage activation syndrome. To determine the role of activation of the complement cascade the most important complement factors and their activation markers will be measured. The changes of those parameters will be monitored after administration of an anti-IL6R antibody therapy.

Study Arms (2)

Ventilation support

EXPERIMENTAL

The experimental group will include Covid-19 infected patients with non-invasive or invasive ventilation support (BCRSS score ≥3).

Diagnostic Test: Cytokines dosageDiagnostic Test: Complement dosage

Control group

OTHER

The control group will include Covid-19 infected patients who don't have respiratory problems justifying a transfer to intensive care.

Diagnostic Test: Cytokines dosageDiagnostic Test: Complement dosage

Interventions

Cytokines dosageDIAGNOSTIC_TEST

Dosage of inflammatory cytokines and other markers of systemic inflammatory syndromes (TNFa, IFNg, IL1, IL7, IL10, IL12, IL17, sCD25, sCD163, sCD14, IL-6, IL6-R, complex IL6-IL6R, glycolsylated ferritin...).

Control groupVentilation support
Complement dosageDIAGNOSTIC_TEST

Dosage of the complement parameters: CH50, C3, C4, C3d, C5a, SC5b-9, C4a, MASP-2.

Control groupVentilation support

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • End of the initial phase of high viral load of SARS-Cov-2 (for example apyretic\> 72h and / or at least 7 days after the onset of symptoms)
  • Worsening of respiratory exchanges which require non-invasive or invasive ventilation support (BCRSS score ≥3)
  • High levels of IL-6 (\> 40 pg / ml); alternatively high levels of d-dimer and / or PCR and / or ferritin and / or fibrinogen gradually increase.
  • A control group will be formed by patients in the Covid unit who do not have respiratory problems justifying a transfer to intensive care.

You may not qualify if:

  • Documented sepsis caused by other pathogens other than SARS-Corv-2.
  • Presence of comorbidities likely to lead, according to clinical judgment, to an unfavorable result
  • Immunosuppressive anti-rejection therapy
