Novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) became pandemic by the end of March 2020. In contrast to the 2002-2003 SARS-CoV outbreak, which had a higher pathogenicity and lead to higher mortality rates, SARSCoV-2 infection appears to be much more contagious. ⋯ This paper summarizes the current state of art about the differences and similarities between the pathogenesis of the two coronaviruses, focusing on receptor binding domain, host cell entry and protease activation. Such differences may provide insight into possible intervention strategies to fight the pandemic.

At present, there is no definitive antiviral treatment for coronavirus disease 2019 (COVID-19). We describe our early experience with remdesivir in four critically ill COVID-19 patients. Patients received a 200 mg loading dose, followed by 100 mg daily intravenously for up to 10 days. ⋯ Nasal swab SARS-CoV-2 RNA became negative in three of four patients after 3 days of therapy. We observed an in vivo virological effect of remdesivir in four critically ill, COVID-19 patients, coupled with a significant burden of adverse events. Although limited by the low number of subjects studied, our preliminary experience may be relevant for clinicians treating COVID-19.

Case Reports
Baricitinib as rescue therapy in a patient with COVID-19 with no complete response to sarilumab.
A patient with COVID-19-related severe respiratory failure, with insufficient response to an antiretroviral therapy, hydroxychloroquine and Interleukin-6 (IL-6) antagonist therapy, presented a prompt resolution of the respiratory function and improvement in the radiological picture after baricitinib at an oral dose of 4 mg per day for 2 weeks.
