Although still under investigation, ADE has been proposed as a potential mechanism underlying the newly described MIS-C, based on the observation that a majority of the patients have evidence of existing antibodies to SARS-CoV-2 and the inflammatory condition seems to lag behind the COVID-19 infection peak by approximately 4-6 weeks. The rationale for use of IL-6 blockade in serious COVID-19 infections is based on the observation that for the subset of patients with severe manifestations, IL-6 is most likely one of the drivers of the cytokine storm, and elevated levels of IL-6 have been consistently shown [14] . ./cache/cord-254777-h8hw4m9f.txt ./txt/cord-254777-h8hw4m9f.txt
