Core Tip

Core Tip: Two years after the onset of the pandemic the search for the most appropriate treatment of coronavirus disease 2019 (COVID-19) continues. Few treatments have been evaluated in the context of critically ill patients with COVID-19 considering it in most clinical trials as a negative “end point” of the disease rather than a study subject. This fact makes it extremely difficult to establish degrees of recommendation regarding the different therapeutic options currently available. This review aims to summarize the immunopathogenesis and the current evidence regarding the different immunomodulatory strategies tested in critically ill patients with COVID-19. In addition, the presence of different immunophenotypes that in the future will serve as a basis for individualized treatments is demonstrated.
