Ferritin, the cellular protein storage for iron, has emerged as a key molecule in the immune system, orchestrating the cellular defense against inflammation. At the end of 2019, the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) rapidly spread throughout China and other countries around the world, resulting in a viral pandemic. ⋯ In this preliminary cross-sectional study, elevated ferritin levels were shown to correlate with disease severity in 39 patients from Israel with confirmed COVID-19 infection. Our results further strengthen the hypothesis that severe COVID-19 disease might be due to an underlying dysregulated hyperimmune response. In order to identify these patients early and prioritized resources, we believe that all patients with COVID-19 should be screened for hyperferritinemia.

A virally-induced cytokine storm syndrome, associated with a massive and overwhelming systemic inflammation, burdens a subgroup of patients with severe coronavirus disease-2019 (COVID-19), which leads to pulmonary inflammation and extensive lung damage. These severe COVID-19 patients are characterized by high ferritin levels. These findings mirror what was previously reported about the prognostic role of this iron storage protein in other inflammatory diseases included in the hyperferritinemic syndrome. ⋯ Considering its activity as an immune activator, a therapeutic approach targeting ferritin may be also postulated in these diseases. Considering these observations, high ferritin levels characterize severe COVID-19 and other diseases included in the hyperferritinemic syndrome. Because ferritin could enhance the inflammatory process, it could be tested as a possible new therapeutic target to improve the outcome of these patients.

The 2019 severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic continued into 2020, and the coronavirus disease-2019 (COVID-19) associated death toll increased. ⋯ The results seem to confirm an association between BCG-positive vaccination policy and salmiak consumption, and lower death rates from COVID-19. Implementing BCG vaccination policy and fortification of foods with salmiak (NH4Cl) may have a significant impact on the control of SARS-CoV epidemic.
