Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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 patient's 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).
