Brief summary
The purpose of this study is to collect blood from previously COVID-19 infected persons who have recovered and use it as a treatment for those who are currently sick with a severe or life-threatening COVID-19 infection.
Detailed description
The purpose of this prospective interventional study is to gain clinical experience using convalescent plasma transfusion administered to critically ill patients with COVID-19. 1 To study the efficacy of plasma from patients recovered from COVID-19 infection with a high neutralizing antibody titer (NAT) as treatment for individuals who are critically ill with COVID-19. 2\. Determine if the antibodies from convalescent plasma will suppress virus load in critically ill patients with COVID-19.

| Viral Load | Day 0, Day 3, Day 5, and Day 7 | Median Viral Load at Day 0, Day 3, Day 5, and Day 7 Plasma Viral Load was measured using a research-use only real-time reverse transcription polymerase chain reaction (rRT -PCR) method which targets two regions of the SARS-CoV-2 N gene using TaqMan chemistry. The limit of detection for this assay is 75 copies/mL (standard curve of 75 copies/mL to 10,000,000 copies/mL of in vitro transcribed RNA prepared from the full SARS-CoV-2 N gene). |
| Serum Antibody Titers | Day 0, Day 3, Day 5, and Day 7 | Median Serum Antibody Titers at Day 0, Day 3, Day 5 and Day 7 Serum Antibody titers were measured using chemiluminescent SARS-CoV-2 immunoglobulin G (IgG) assay from Diazyme (Poway, CA) Positive IgG serum value is \> or = 1.0 arbitrary units/mL \[AU/mL\] (linear reportable range for IgG is 0.20 - 100.00 AU/mL) |

Mortality
Mortality within 28 days
Time frame: Up to 28 days
Population: 48 patients with severe or life threatening disease with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection enrolled in the study. 7 patients were excluded from analysis due to receiving plasma with insufficient antibodies.

Serum Antibody Titers
Median Serum Antibody Titers at Day 0, Day 3, Day 5 and Day 7 Serum Antibody titers were measured using chemiluminescent SARS-CoV-2 immunoglobulin G (IgG) assay from Diazyme (Poway, CA) Positive IgG serum value is \> or = 1.0 arbitrary units/mL \[AU/mL\] (linear reportable range for IgG is 0.20 - 100.00 AU/mL)
Time frame: Day 0, Day 3, Day 5, and Day 7
Population: 39 out of 41 patients had blood collected on day 0 (pre-transfusion), and on post-transfusion day 3 (n=36), 5 (n=30), and 7 (n=24) and serum antibody titers was assessed at each time point.

Viral Load
Median Viral Load at Day 0, Day 3, Day 5, and Day 7 Plasma Viral Load was measured using a research-use only real-time reverse transcription polymerase chain reaction (rRT -PCR) method which targets two regions of the SARS-CoV-2 N gene using TaqMan chemistry.
