Official Title
A Retrospective Study of Evaluating Safety and Efficacy of Tocilizumab Compared to Continuous Renal Replacement Therapy in Controlling CRS Triggered by COVID-19
Brief Summary

Some patients infected with the COVID-19 can develop uncontrolled immune response, leading to potentially life-threatening damage to lung tissue. Tocilizumab was first approved by the U.S. FDA in 2010 for rheumatoid arthritis and might now be used to treat serious COVID-19 patients with lung damage, according to China's National Health Commission updated its treatment guidelines in 7th version.Continuous Renal Replacement Therapy (CRRT) was recommended by China's National Health Commission treatment guidelines in 1st-7th version to control sever COVID-19 patients.

Detailed Description

Tocilizumab doesn't directly kill the novel coronavirus. It's known as an inhibitor of the receptor of interleukin 6 (IL-6), a pro-inflammatory cytokine. In the disease COVID-19, the body may respond to the pathogen by overproducing immune cells and their signaling molecules in a dangerous phenomenon called cytokine release storm.It has been recently speculated that IL-6 as a main culprit in that immune over activation among COVID-19 patients, hence the Tocilizumab clinical trial was initiated. In 2017, the FDA also approved Tocilizumab to treat cytokine release syndrome (CRS), a form of cytokine storm caused by CAR-T treatment. The investigator's hypothesis was that Tocilizumab would be associated with better clinical outcomes, such as decreased systemic inflammation, improved survival rate, better hemodynamic and improved of respiratory distress.Systemic inflammatory response syndrome was one of the main indications for treatment with CRRT. So it is clinically significant to compare the efficacy and safety of Tocilizumab and CRRT in management of CRS triggered by COVID-19.
