Brief summary

The COVID-19 pandemic has been spreading continuously, and in Brazil, until August 18, 2020, there have been more than 3,359,000 cases with more than 108,536 deaths, with daily increases. The present study proposes to evaluate the efficacy and safety of using convalescent plasma for treating patients with COVID-19 pneumonia without indication of ventilatory support.

Interventions

BIOLOGICALConvalescent plasma

The intervention group will receive 400 mL of convalescent plasma with a SARS-CoV-2 antispike antibody titer with a dilution ≥ 1: 320.

Primary

MeasureTime frameDescription
Area under the curve of SARS-COV-2 viral load obtained from nasopharyngeal and /or oropharyngeal swabs.0, 3, 6, 9, 12, 15, 18 and 21 daysTo evaluate the area under the curve of SARSCoV-2 viral load in nasopharyngeal and or oropharyngeal samples on days 0, 3, 6, 9, 12, 15, 18 and 15 after randomization.

Secondary

MeasureTime frameDescription
Evaluate oxygen saturation0, 3, 6, 9, 12, 15, 18 and 21 days
Evaluate oxygen supplementation0, 3, 6, 9, 12, 15, 18 and 21 days
Assess respiratory rate0, 3, 6, 9, 12, 15, 18 and 21 days
Evaluate the PaO2 / FiO2 ratio (for patients on mechanical mechanisms)0, 3, 6, 9, 12, 15, 18 and 21 days
Length of hospital stay21 days
Assessment of clinical improvement using an Ordinal Severity Scale0, 7, 10, 14, 21 and 28 daysThe seven-point scale is as follows: * Death 7 points; * Hospital admission for mechanical ventilation plus additional organ support (eg, pressors, RRT, ECMO) = 6 points; * Hospital admission for mechanical ventilation = 5 points; * Hospital admission for non-invasive ventilation or high-flow oxygen therapy = 4 points; * Hospital admission for oxygen therapy (but not requiring high-flow or non-invasive ventilation) = 3 points; * Hospital admission but not requiring oxygen therapy = 2 points; * Discharged with limitations of activities = 1 point; * Discharged with no limitations of activities = 0 point;
Assess the rate of orotracheal intubation21 days
Change in the profile of cytokines/chemokines in both groups0, 3, 6, 9, 12, 15, 18 and 21 daysQuantification by ELISA the levels of 36 molecules determined simultaneously using the Human Cytokine Array Kit da R&D Systems (C5a, IL-4, IL-32 alpha, CD40 ligand, IL-5, CXCL10 / IP-10, G-CSF, IL-6, CXCL11 / I-TAC, GM-CSF, IL-8, CCL2 / MCP-1, CXCL1 / GRO alpha, IL-10, MIF, CCL1 / I-309, IL-12 p70, CCL3 / MIP-1 alpha, ICAM-1, IL-13, CCL4 / MIP-1 beta, IFN -gamma, IL-16, CCL5 / RANTES, IL-1 alpha, IL-17, CXCL12 / SDF-1, IL-1 beta, IL-17E, Serpin E1 / PAI-1, IL-1ra, IL-23, TNF-alpha, IL-2, IL-27 and TREM-1)
