The COVID-19 (coronavirus disease 2019) outbreak, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), started in December 2019 in Wuhan, China, has been recently declared a pandemic 1 by the World Health Organization (WHO), becoming a major health concern worldwide. The pathogenesis of the disease is still under investigation, but it seems to be strictly related to an uncontrolled immune response that leads to a massive cytokine storm and subsequently to tissue damage. 2 Different immunomodulator treatments have been proposed to contrast this potentially fatal cytokine release syndrome, including (IL)-6 receptor inhibitors (tocilizumab; sarilumab), an IL-1 receptor antagonist (anakinra) and jak-inhibitors, such as baricitinib. Furthermore, another drug class, TNFα inhibitors, has been considered for SARS coronavirus infection. 3
