    Cytomegalovirus reactivation in seropositive patients receiving CAR-T therapy is linked to treatment failure and inferior outcomes.

  • 2

    A federated digital twin model was developed to test the cytokine sink hypothesis, revealing competition for homeostatic cytokines.

  • 3

    The model predicted CMV reactivation with high accuracy, outperforming existing clinical risk scores in assessing treatment outcomes.

  • 4

    In silico simulations indicated that a digital twin-guided antiviral prophylaxis strategy could reduce progression while minimizing drug exposure.

  • 5

    Formal analysis supports the cytokine sink hypothesis, necessitating randomized trials for definitive causal proof and clinical validation.
