Analysis of Coronavirus Disease 19 (COVID-19) Convalescent Plasma

PRIMARY OBJECTIVES: I. Establish a testing service for screening prospective donors of coronavirus disease 2019 (COVID-19) convalescent plasma (CCP). II. Characterize the titer and neutralizing properties of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in CCP. III. Correlate the SARS-CoV-2 antibody characteristics in CCP with the outcome in severely ill COVID-19 patients treated with CCP. EXPLORATORY OBJECTIVES: I. Facilitate the recruitment of CCP donors in medically underserved areas. II. Develop high-throughput methods for detection/characterization of SARS-CoV-2 neutralizing and non-neutralizing antibodies. III. Develop a bank of convalescent plasma that would be available for future studies relating to the content of CCP. IV. Study the impact of antibody levels, donor characteristics and patient characteristics on outcome in COVID-19 patients treated with CCP. V. Procure blood samples from COVID-19 convalescent volunteers for future COVID-19-related studies. OUTLINE: PROSPECTIVE CCP DONORS: Participants undergo collection of blood and/or nasopharyngeal swabs at the time of screening. Participants' medical records are reviewed. CONVALESCENT BLOOD DONORS WHO CHOOSE NOT TO DONATE CCP: Participants undergo collection of blood sample at the time of screening. Participants' medical records are reviewed. CCP RECIPIENTS: Patients undergo collection collection of blood samples at baseline, between CCP unit infusions, 24 hours after last CCP infusion, and between 14-28 after last CCP infusion. Patients' medical records are reviewed.
