ABSTRACT
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first known case was identified in Wuhan, China, in December 2019. The disease has since spread worldwide, and on March 2020 the World Health Organization (WHO) declared it as pandemic, causing a public health crisis. Symptoms of COVID-19 are variable, ranging from mild symptoms like fever, cough, and fatigue to severe illness. Elderly patients and those with comorbidities like cardiovascular disease, diabetes, chronic respiratory disease, or cancer are more likely to develop severe forms of the disease. Asymptomatic infections have been well documented. Accumulating evidence suggests that the severity of COVID-19 is due to high levels of circulating inflammatory mediators including cytokines and chemokines leading to cytokine storm syndrome (CSS). Patients are admitted in ICU with severe respiratory failure, but can also develop acute renal failure and multi organ failure. Advances in science and technology have permitted the development of more sophisticated therapies such as extracorporeal organ support (ECOS) therapies that includes renal replacement therapies (RRTs), venoarterial (VA) or veno-venous (VV) extracorporeal membrane Oxygenation (ECMO), extracorporeal CO2 removal (ECCO2R), liver support systems, hemoperfusion, and various blood purification devices, for the treatment of ARDS and septic shock.
