NCT06402279

Brief Summary

The development of acute respiratory and renal failure of COVID-19 patients is associated with an excessive immune response and hyperproduction of anti-inflammatory cytokines, which leads to impaired endothelial function and a dysregulated balance between the coagulation and fibrinolytic systems in the blood. These factors contribute to the development of multi-organ failure, sepsis, and high mortality rates.In the absence of effective etiotropic therapy for COVID-19, it is necessary to search for alternative, pathogenetically based treatment approaches, including extracorporeal methods of homeostasis support. This observational study examines the effect of early hemoperfusion using the Efferon CT device for the treatment of patients with severe forms of COVID-19 after their intubation on a ventilator.

Outcome Measures

Primary Outcomes (1)

  • Effect of Efferon CT hemoperfusion on Ventilator-free days (VFDs)

    VFDs is a composite outcome measure that combines survival and duration of ventilation.

    1-60 days

Secondary Outcomes (4)

  • Effect of Efferon CT hemoperfusion on SOFA scores

    1-10 days

  • Effect of Efferon CT hemoperfusion on pulmonary oxygen metabolism function

    1-10 days

  • Effect of Efferon CT hemoperfusion on KDIGO stage

    1-10 days

  • Effect of Efferon CT hemoperfusion on the need for norepinephrine

    1-10 days

Study Arms (2)

Basic therapy + Efferon CT

Patients in group 1 (n = 65) received basic COVID-19 medication: 2 to 5 days before hemosorption, they all received anti-inflammatory drugs, glucocorticoid therapy (16 to 24 mg/day of dexamethasone), oxygen therapy, and heparin. The transfer to an intensive care unit (ICU) was accompanied by transfer to a non-invasive ventilator.

Device: Efferon CT therapy

Baseline therapy

Group 2 patients (n=65) were matched to patients of group 1 and received basic COVID-19 drug therapy and no hemoperfusion procedure using Efferon CT device.

Interventions

Efferon CT is a cylindrical body made of polycarbonate, filled with spherical granules of polymer hemocompatible macroporous styrene-divinylbenzene copolymer of super cross- linked type and isotonic sodium chloride solution. The device is manufactured according to TU 32.50.50-001-12264678-2018, has passed the necessary tests and is registered in Russia as a medical product RZN 2019/8886. Hemoperfusion procedures were performed using the Efferon CT device no later than 6 hours after the start of invasive ventilation. Hemosorption was performed twice within 12 hours, with an interval of 24 hours between hemoperfusion.
