This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
RationaleElevated levels of inflammatory cytokines have been associated with poor outcomes among COVID-19 patients. It is unknown, however, how these levels compare to those observed in critically ill patients with ARDS or sepsis due to other causes. ObjectivesTo directly compare plasma levels of inflammatory cytokines, with a focus on 6 cytokines associated with cytokine storm (IL-1b, IL-1RA, IL-6, IL-8, IL-18, and TNF), between hospitalized COVID-19 patients and banked plasma samples from ARDS and sepsis patients from prior to the COVID-19 pandemic. Findings15 hospitalized COVID-19 patients, 9 of whom were critically ill, were compared to 28 critically ill patients with ARDS or sepsis. There were no statistically significant differences in baseline levels of IL-1b, IL-1RA, IL-6, IL-8, IL-18, and TNF between patients with severe COVID-19 and critically ill controls with ARDS or sepsis. ConclusionsLevels of inflammatory cytokines IL-1b, IL-1RA, IL-6, IL-8, IL-18, and TNF were not higher in critically ill COVID-19 patients than in critically ill patients admitted with ARDS or sepsis due to other causes in this small cohort. Broad use of immunosuppressive therapies in ARDS has failed in numerous Phase 3 studies; use of these therapies in unselected patients with COVID-19 is likely unwarranted.
