Glucocorticoid use as a cause of non-cellular immune response to SARS-Cov2 Spike in patients with immune system diseases

Résumé

Disease modifying therapies compromise immune response to SARS-Cov2 or its vaccine in patients with immune system diseases (ISD). Therefore, analysis of the humoral and cellular responses against Spike is of utmost importance to manage ISD patients. A single-center retrospective study was conducted to evaluate the impact of COVID-19 immunization in 87 ISD patients and 81 healthy controls. We performed a whole blood interferon gamma release assay using SARS-Cov2 Spike and Nucleocapsid recombinant proteins in order to evaluate T-cell memory response, and an IgG anti-Spike ELISA to evaluate humoral response. Cellular (26.4%) and humoral (44.8%) responses were negative against Spike in ISD patients following COVID-19 immunization. In univariate analysis, an anti-Spike T cell defective response was associated with the use of glucocorticoids (Odds ratio [OR] = 10.0; p < 10-4), serum albumin level ≤40 g/L (OR = 18.9; p < 10-4), age over 55 years old (OR = 3.9, p = 0.009) and ≤2 vaccine injections (OR = 4.9; p = 0.001). The impact of glucocorticoids persisted after adjustment for age and number of vaccine injections (OR = 8.38, p < 0.001). In contrast, the humoral response was impacted by the use of anti-CD20 mAb (OR = 24.8, p < 10-4), and an extended time since immunization (≥75 days; OR = 4.3, p = 0.002). Double defective cellular/humoral responses (6.9%) were typically encountered in glucocorticoids and/or anti-CD20 mAb treated ISD with a serum albumin level ≤40 g/L (OR = 17.5; p = 0.002). Glucocorticoid usage, B cell depleting therapies, and a low serum albumin level were the main factors associated with a non-response to COVID-19 immunization in ISD patients. These results need further confirmation in larger studies.
