Convalescent plasma is a way to provide passive immunity to a person exposed to an infectious agent. It has been used as a therapeutic tool for emerging viral infections without specific treatment and with high morbidity and mortality, such as Influenza H1N1, H5N1, H7N9, Ebola, MERS, SARS-CoV1, and even SARS-Cov2, with satisfactory results regarding evolution clinic of patients treated and without significant adverse events reported. One of its main advantages of convalescent plasma is to generate a rapid immune response (even faster than a vaccine), against a pathogen that circulates in a specific geographic area, probably common for both donor and recipient.
This study consists of obtaining convalescent plasma by means of apheresis, from recovered donors, who meet the eligibility criteria to donate. Then this plasma will be inactivated by riboflavin and UV based photochemical treatment (Mirasol technology - Terumo BCT®), in order to add more transfusion security to the procedure. Finally, it will be transfused to CoViD-19 patients hospitalized in any of the participating clinics. There are currently no reported significant adverse events associated with this therapy. Have been published two serial cases reports,more evidence is necessary to standardize the treatment.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Convalescent plasma+Support treatment selected by the hospital | Experimental | Participants will receive two doses of ABO - Rh compatible inactivated convalescent plasma, each one of 200 mililiters (mL), with a 24-hour interval via transfusion, for a final volume of 400 mL, meanwhile they continue to receive the supportive treatment chosen by the hospitals, according to each institutional protocol. |
|
| Support treatment selected by the hospital | Active Comparator | The best support treatment selected by the hospital, according to each institutional protocol. Due to the ongoing development of knowledge of pathophysiology and scientific evidence of the available alternatives, it will be selected at the time of treatment. |
