NCT04643639

Brief Summary

In this randomized, open-label study, the investigators will assess whether CytoSorb hemoperfusion will prevent or attenuate the development of immunoparalysis in healthy volunteers undergoing repeated experimental endotoxemia.

Outcome Measures

Primary Outcomes (1)

  • Between group differences in plasma interleukin (IL)-6 levels during the second endotoxin challenge.

    Blood samples will be obtained at predefined time points before, during and after endotoxin administration to assess plasma levels (in pg/mL) of circulating inflammatory mediatiors. To assess between group differences, the area under the curve (AUC) of the time concentration curve (expressed in arbitrary units) of each inflammatory mediator will be calculated.

    Samples will be obtained starting 1 hour prior until 8 hours after endotoxin administration

Secondary Outcomes (10)

  • Between group differences in plasma levels of other inflammatory cytokines during the second endotoxin challenge.

    Samples will be obtained starting 1 hour prior until 8 hours after endotoxin administration

  • Between group differences in mHLA-DR expression

    1 hour before, 3 hours after and 6 hours after endotoxin administration

  • Between group differences in norepinephrine sensitivity

    One hour before and 4 hours after endotoxin administration during the first endotoxin challenge

  • Cytokine clearance by the adsorber

    Every 30 minutes until cessation of hemoperfusion (six hours after endotoxin administration)

  • Between group differences in endotoxemia-induced metabolic activity of platelets

    1 hour prior until 8 hours after endotoxin administration

  • +5 more secondary outcomes
