Nevertheless, a study of 41 patients with large B-cell lymphoma suggested a more significant burden of herpesviruses, affecting a quarter of their cohort, with one case of HHV-6 meningoencephalitis in the first 28 days, four cases of CMV reactivation within two weeks of glucocorticoid initiation, and six cases of herpes zoster occurring beyond 28 days post CD19 CAR-T [6]. The gene discussed is CD19; the disease is B-cell non-Hodgkin lymphoma.
