Convalescent Plasma Therapy in Patients With COVID-19

Scientists and medical workers all around the world were running out of time to manage COVID-19. Several studies have been done to understand the disease and ultimately to find possible treatment. Based on those studies, one of the potential treatment was antibody transfer from recovered COVID-19 patients. Passive antibody transfer was a fast and easy choice. The rational use of antibody from the patient's plasma is a natural neutralizing protein to the cell-infected virus and could possibly slow the active infection down. Investigators initiate an intervention study with purposes to produce quality convalescent plasma from the recovered patients, define the safety of plasma for human use and as an alternative treatment to improve the clinical outcomes of severe COVID-19 patients. The study hypothesis is convalescent plasma is safe and could possibly improve outcome of severe (non-critical) COVID-19 patients. This research will conduct the plaque reduction neutralizing test (PRNT) of recipient blood in vitro. The plasma will be collected in the blood transfusion unit (BTU) in Gatot Soebroto hospital. The storage, testing, transfer, and transfusion of eligible convalescent plasma are the authority of Gatot Soebroto BTU. PRNT and plasma antibody titer measurement from donor plasma will be conducted at Eijkman Institute of Molecular Biology. Investigators enroll approximately 10 patients consecutively, who will be admitted at Gatot Soebroto hospital. Baseline demographic characteristics of samples are recorded. Clinical dan laboratory data will be measured before and after plasma transfusion periodically. The measured variables are pharmacological therapy (antivirus, antibiotics, steroids), invasive oxygen therapy, oxygen index, sequential organ failure assessment (SOFA) score, and laboratory parameters such as leukocyte count, blood chemical panel include liver and renal function, C-reactive protein, procalcitonin, IL-6 and immunoglobulin titer of the recipient and
