Plasma transfusion receptor: be 18 years or older; have been admitted to a hospital to treat moderate Covid-19, defined as compatible clinical characteristics, such as dyspnea and/or fever and/or cough plus chest computed tomography with bilateral ground glass opacities; have SARS-CoV-2 infection confirmed by nasopharyngeal and/or oropharyngeal swab PCR or serological assay that detects IgM or SARS-CoV-2 antigen; have Covid-19 symptoms for no more than 10 days.
Plasma donor: at the interview and research subject selection stage: history of severe Covid-19 in the last 30 days (septic shock, cardiac arrest or intubation for more than two days); previous history of coagulation diseases than could increase the venous access risk; previous history of hemoglobinopathies that could increase the plasmapheresis risk; situations that prohibit blood donations, according to Brazilian law (Portaria de Consolidação n.5, de 28 de setembro de 2017). At the pre-plasmapheresis stage: positive result in an irregular antibody test made with serum collected during triage; detection of anomalous hemoglobin (e.g. sickle cell trait) in a whole blood sample obtained during triage; negative result on a test for SARS-CoV-2 IgG; ineligibility for blood donation identified during triage, as specified at the relevant Brazilian law (Portaria de Consolidação n.5, de 28 de setembro de 2017). Plasma transfusion receptor: respiratory insufficiency with indication for mechanical ventilation; severe sepsis or septic shock; active co-infection with a dengue virus, confirmed by serological detection of the NS1 antigen or RT-PCR; admission to the Intensive Care Unit (ICU); having received intravenous immunoglobulin (IVIG) in the last 30 days; history of allergy or hypersensitivity to a blood product transfusion; heart or renal insufficiencies that makes the excess volume from plasma transfusion not advisable; in women, present pregnancy, plans to get pregnant in the following two months or breastfeeding; be part of another clinical trial.
