This invention discloses a predictive model for early fever and infection after CAR-T therapy. The equation for this predictive model is: P = 1 / (1 + e^(-3.23 + 0.017 × CRP + 0.003 × IL - 6 - 0.023 × platelet count - 8.048 × lymphocyte count - 1.241 × FCV + 1.6146 × neutropenia grade)); where P is the probability of infection. P < 0.20 is defined as low risk, classified as CRS; 0.2 ≤ P ≤ 0.6 is defined as medium risk, requiring further testing to determine whether it is infection or CRS; P > 0.6 is defined as high risk, classified as infection. This predictive model is used to predict the likelihood of infection in the first fever event after CAR-T therapy. By analyzing various clinical laboratory indicators and combining logistic regression analysis, the model screens out key predictive factors related to infection risk, ultimately establishing an efficient and easy-to-use predictive tool. This model can effectively predict the occurrence of infection, provide clinicians with guidance for early intervention, reduce unnecessary clinical testing, and optimize patients' treatment plans.

Adverse outcomes of CAR-T such as hematotoxicity with prolonged cytopenia and infectious complications represent a challenging clinical problem after CAR-T therapy; however, current predictive models rely on blood counts and general inflammatory lab markers (ferritin, CRP) only and lack mechanistic / functional insights. Prolonged cytopenias after CAR-T are associated with endothelial alteration, characterized by reduced ANG1, E-selectin and MMP-1, and increased ANG2:ANG1 ratio, VCAM-1 and Thrombomodulin early after CAR-T. It was found that Patients with high baseline sIL-2R and VCAM-1 not only show more prolonged neutropenia and a more aplastic neutrophil recovery but also experience more severe infectious complications. High baseline VCAM-1 is associated with significantly worse peak CD8 CAR-T cell expansion and separates MM patients with worse overall response (Figure 5, Figure s5) Baseline sIL-2R and VCAM-1 have high predictive value for adverse outcomes, such as prolonged neutropenia, severe infections and death, and can further improve existing models.
