Analysis of related factors of plasma antibody levels in patients with severe and critical COVID-19

© 2024. The Author(s)..

Coronavirus disease 2019 (COVID-19) continues to impact global public health. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become less virulent as it mutates, prompting China to ease restrictions at the end of 2022. With the complete reopening, a surge in COVID-19 cases has ensued. Therefore, we conducted a study to explore the correlation between plasma antibody levels and baseline conditions or clinical outcomes in severe and critical patients. We collected the basic information of 79 included patients. Enzyme-linked immunosorbent assay (ELISA) tests were performed on plasma samples. The receptor-binding domain (RBD) IgG antibody level of the mild group was significantly higher than that of the severe/critical group (P = 0.00049). And in the severe/critical group, there existed an association between plasma antibody levels and age (P < 0.001, r = - 0.471), as well as plasma antibody levels and vaccination status (P = 0.00147, eta2 = 0.211). Besides, the level of plasma antibody seemed to be moderately correlated with the age, indicating the need for heightened attention to infections in the elderly. And plasma antibody levels were strongly associated with vaccination status in the severe/critical patients.
