Therapeutic Plasmapheresis in Critically Ill Adult Patients With COVID-19 Confirmed Diagnosis
- Conditions
- COVID-19
- Interventions
- Biological: Convalescent plasma
- Registration Number
- NCT04480632
- Lead Sponsor
- Fundación Cardiovascular de Colombia
- Brief Summary
Introduction: The SARS-CoV-2 outbreak has left more than two million infected worldwide in the first four months of COVID-19 epidemic. To date, there is no specific treatment for the disease and in critically ill patients there is an additional challenge in controlling the systemic inflammatory response, which is characterized by cytokine storm, alteration in coagulation and endothelial activation in addition to infection. Strategies used in previous viral epidemics, such as convalescent plasma, are therapeutic options to rescue, especially in individuals with a critical presentation of the disease.
Aim: To establish clinical response of critically ill patients with COVID-19 who received convalescent plasma from subjects recovered from SARS-CoV-2 during their stay in Intensive Care Unit at Fundación Cardiovascular de Colombia (Hospital Internacional de Colombia).
Methodology: Quasi-experimental study (no randomization will be performed). Adult patients who meet selection criteria will receive 500 ml of ABO compatible convalescent plasma, obtained by apheresis from patients recovered from SARS-CoV-2 infection. The main outcome will be in-hospital mortality at 30 days, while indication for ventilatory support (intubation) and adverse events at thirty days will be evaluated as secondary outcomes, compared to subjects receiving usual treatment for clinical sign and symptoms given the absence of ABO compatible plasma units. A survival analysis will be performed using Kaplan-Meier method and association strength will be reported using HR and 95% CI crude and adjusted for confounding variables.
Expected results: It is expected to know the clinical and paraclinical response of patients receiving convalescent plasma in our institution, as well as to establish their probability of survival and its associated factors.

Group Intervention Description ABO compatible convalescent plasma Convalescent plasma A 500 ml dose of convalescent plasma (from a single donor or two 250 ml units from one or two donations) collected by apheresis will be administered. In case of plasma storage, plasma unit will be thawed following parameters of blood bank. Administration will take place slowly and over the course of four hours. When two 250 ml units are administered, second unit must be administered after the first unit in a period not exceeding 12 hours.
