COVID-19 Patients Exhibit Early Antibody Signatures Potentially Predictive of Death or Recovery

Researchers at the Ragon Institute of MGH, MIT and Harvard, and the University of Washington (UW) School of Medicine, have identified five immune response markers that, collectively, were able to distinguish between those COVID-19 patients who convalesced from the infection, and those who didn’t survive the disease. The researchers used a systems serology technique to generate a detailed profile of SARS-Co-2-specific humoral—antibody generating—responses in hospitalized patients, which they validated in a second patient cohort. The findings indicated that individuals who survived COVID-19 infection and those who died exhibited antibody responses that were primarily directed against different SARS-CoV-2 proteins.
