Convalescent Plasma for Treating Patients With COVID-19 Pneumonia Without Indication of Ventilatory Support
- Conditions
- COVID-19
- Interventions
- Biological: Convalescent plasma
- Registration Number
- NCT04528368
- Lead Sponsor
- D'Or Institute for Research and Education
- 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.

- Primary Outcome Measures
Name Time Method 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 days To 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 Outcome Measures
Name Time Method Length of stay in intensive care 21 days Assess the rate of orotracheal intubation 21 days Evaluate the PaO2 / FiO2 ratio (for patients on mechanical mechanisms) 0, 3, 6, 9, 12, 15, 18 and 21 days Change in the profile of cytokines/chemokines in both groups 0, 3, 6, 9, 12, 15, 18 and 21 days Quantification 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)
Assessment of clinical improvement using an Ordinal Severity Scale 0, 7, 10, 14, 21 and 28 days The 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 respiratory rate 0, 3, 6, 9, 12, 15, 18 and 21 days Presence of antibodies against SARS-CoV-2 in serum after convalescent plasma administration 0, 3, 6, 9, 12, 15, 18 and 21 days Death rate 7, 10, 14, 21 and 28 days Evaluate oxygen saturation 0, 3, 6, 9, 12, 15, 18 and 21 days Evaluate oxygen supplementation 0, 3, 6, 9, 12, 15, 18 and 21 days Length of hospital stay 21 days Rate of transfusion reactions to convalescent plasma infusion 21 days
