Background: An excessive immune response during coronavirus disease (COVID-19) can induce cytokine release syndrome (CRS), which is associated with life-threatening complications and disease progression. Methods: This study was aimed to investigate the differences and similarities between CRS induced by COVID-19 and CAR-T therapy, then provide valuable experiences for early identification and controlling CRS progression in COVID-19. We retrospectively evaluated the clinical characteristics of severe CRS (sCRS, grade 3-4) induced by COVID-19 (40 patients) or chimeric antigen receptor T-cell (CAR-T) therapy as a comparator (41 patients). Results: Grade 4 CRS was significantly more common in the COVID-19 group (15/40 [35.7%] vs. 5/41 [12.2%], P=0.008). CAR-T group had more more dramatic increase in cytokine than COVID-19 group (Figure1), including IL-2 (7.3pg/mL [IQR: 2.0-12.7] vs.1.7 [0.7-2.7], P<0.001), IL-6 (7120.6 pg/mL [1066.8-15 136.4] vs. 110.3 [41.7-728.1], P<0.001), IL-10 (174.5pg/mL [61.7, 434.6] vs. 10.1 [6.3-20.6], P<0.001) and IFN-γ (1308.5pg/mL [296.6, 3108.2] vs .35.0 [16.9-60.8], P<0.001). Interestingly, COVID-19 group had significantly higher levels for TNF-α (31.1 pg/ml [16.1-70.0] vs. 3.3 [1.8-9.6], P<0.001).The correlations between viral load/ tumor burden and various cytokine levels were shown in Figure 2. Lg viral loads were correlated with lg IL-6 (R2=0.101; P<0.001) and lg IL-10 (R2=0.105; P<0.001) .In CAR-T group, LDH was a common indicator related to tumor burden among patients with ALL, NHL, and MM. The lg LDH concentration was correlated with the lg serum concentration of IL-6 (R2=0.161; P=0.01). The independent risk factors for COVID-19-related sCRS were hypertension history (OR: 7.167, 95% CI: 2.345-21.903; P=0.001) and minimum platelets <100×109 /L during disease course (OR: 9.237, 95% CI: 2.544-33.546; P=0.001). Conclusion: Our study demonstrated that there were similar processes but different intensity of inflammatory responses of sCRS in COVID-19 and CAR-T group. The diagnose and management of COVID-19 related sCRS can learn lessons from treatment of sCRS induced by CAR-T therapy.

ABSTRACT In recent years, cancer treatment has evolved, and new therapies have been introduced with significant improvement in prognosis. The immunotherapies stand out owing to their efficacy and remission rate. Chimeric antigen receptor (CAR) T-cell therapy is a part of this new era of therapies. Chimeric antigen receptor T-cell therapy is a form of adoptive cellular therapy that uses a genetically encoded CAR in modified human T cells to target specific tumor antigens in a nonconventional, non-major histocompatibility complex (MHC) protein presentation. Chimeric antigen receptor T-cell therapy successfully identifies tumor antigens and through activation of T cells destroys tumoral cells. It has been found to efficiently induce remission in patients who have been previously treated for B-cell malignancies and have persistent disease. As the use of this novel therapy increases, its potential side effects also have become more evident, including major complications like cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Cytokine release syndrome is a major systemic inflammatory process as a result of massive cytokine production by the proliferating and activated CAR T cells in which multiple interleukins and immune cells contribute to the inflammatory response. Cytokine release syndrome has been associated with cardiovascular life-threatening complications including hypotension, shock, tachycardia, arrhythmias, left ventricular dysfunction, heart failure, and cardiovascular death. Arrhythmias, among its major complications, vary from asymptomatic prolonged corrected QT interval (QTc) to supraventricular tachycardia, atrial fibrillation, flutter, and ventricular arrhythmias like Torsade de pointes. This article focuses on the cardiovascular complications and arrhythmias associated with CRS and CAR T-cell therapy.

Studies describing invasive fungal infections (IFIs) after chimeric antigen receptor-modified T-cell (CAR-T-cell) therapy are limited. Although post-CAR-T-cell IFIs appear to be uncommon, they are associated with significant morbidity and mortality. Specific risk factors for IFIs in CAR-T-cell recipients have not been fully characterized and are often extrapolated from variables contributing to IFIs in patients with other hematologic malignancies or those undergoing hematopoietic cell transplant. Optimal prophylaxis strategies, including the use of yeast versus mold-active azoles, also remain ill-defined. Further research should investigate key risk factors for IFIs and establish an evidence-based approach to antifungal prophylaxis in these patients in order to improve clinical outcomes.
