[Application of immunosuppressive agents in crtical coronavirus disease]

The outbreak of novel coronavirus (SARS-CoV-2) infection has brought great harm to people's life and social development. Although SARS-CoV-2 infection is more common in mild patients at present, considering the characteristics of crtical disease, rapid progress and high mortality, the treatment of critical patients are the focus of clinical attention. Immune imbalance which is characterized by cytokine storm plays a vital role in SARS-CoV-2 induced acute respiratory distress syndrome (ARDS), extrapulmonary multiple organ failure and even death. Therefore, the application of immunosuppressive agent in crtical coronavirus disease patients has a promising prospect. In this paper, different immunosuppressive agents and their application in crtical SARS-CoV-2 infection are reviewed, so as to provide reference for crtical coronavirus disease therapy.
