Excuse me, we already "know"/strongly assume since July that's it's a BK (bradykinin) storm, not cykotine. Not much different, just different treatments needed. https://elifesciences.org/articles/59177
Interesting findings, if confirmed this will no doubt lead to a change in the treatment regime for the more serious cases of COVID-19. Radboud UMC is well regarded and their research rarely, if ever, is found to have been sloppy so I don't think confirmation will be long in the making.
