Brief Summary: Many patients with Coronavirus Disease 2019 COVID-19 have atypical blood clots These blood clots can occur in either veins or arteries and be large like in stroke or heart attack or very tiny called microthrombi Some patients with COVID-19 even have blood clots despite being on anti-clotting medications Blood with increased viscosity does not flow through the body normally in the same way that syrup a highly viscous liquid and water a minimally viscous liquid flow differently The researchers believe that hyperviscosity may contribute to blood clots and organ damage seen in patients with severe COVID-19 Plasma exchange removes a patients plasma which contains the large sticky factors that the researchers believe are increasing viscosity and replaces it with plasma from healthy donors In addition to providing important information about plasma exchange as a treatment in COVID-19 for patients this study will provide data to justify resource and staffing decisions

This study will enroll 20 participants who are critically ill from COVID-19 Participants will be randomized to receive therapeutic plasma exchange TPE or standard of care SOC
Detailed Description: Critically ill COVID-19 patients have high rates of complications including respiratory failure renal impairment and a coagulopathic state that may exacerbate these conditions and contribute to additional end organ injury Consistent with a fundamentally distinct nature of COVID-19-associated disease our preliminary studies demonstrate that patients with COVID-19 exhibit an increase in plasma viscosity Furthermore the researchers have found that plasma viscosity strongly correlates with sequential organ failure assessment SOFA scores a mortality prediction score used in the intensive care unit ICU in COVID-19 infected patients These results strongly suggest that altered blood flow secondary to hyperviscosity may contribute to end organ injury and therefore morbidity and mortality in the most critically ill COVID-19 patients More detailed analysis of the potential etiology of COVID-19-associated plasma hyperviscosity has demonstrated that these patients also have significantly elevated levels of the plasma protein fibrinogen Increased fibrinogen levels which may be either entirely responsible for or at least contribute to hyperviscosity in these patients may be the primary mediator of refractory hypercoagulability in this patient population Thus hyperviscosity induced by hyperfibrinogenemia may be a critical driver of morbidity and mortality in patients with COVID-19

Therapeutic plasma exchange TPE is the only procedure known to directly and rapidly decrease plasma viscosity suggesting that TPE may improve patient outcomes in critically ill patients with COVID-19 by decreasing plasma viscosity and thereby enhancing blood flow However as a procedure extensive implementation of TPE would require significant devotion of hospital resources including apheresis machines and the staff needed to successfully conduct these procedures The procedures alone require staff to have prolonged interactions with critically ill COVID-19 patients placing them at a potentially increased risk for contracting COVID-19 It is therefore essential that clear and unequivocal data be generated in order to accurately assess the risk and benefits of this procedure for both patients and staff Such data will also aid in determining the necessary resources that may be needed to successfully conduct TPE for this patient population

Participants will be randomized in a 11 ratio to receive TPE or SOC Participants in the TPE study arm will receive two treatments of TPE with frozen plasma on sequential days Plasma viscosity will be measured before TPE Day 1 and following the second TPE treatment Day 3 or 4 Participants in the SOC study arm will also have their plasma viscosity assessed on Days 1 and 3 Participants will be followed for the duration of their hospital stay
