Following six cycles of azacitidine treatment, her bone marrow and hemogram returned to normal, and the disease was stable In August 2023, she presented with recurrent fever for over a month and was diagnosed with high-risk DLBCL stage IVB presenting with HLH. After receiving the HLH-1994 protocol followed by one cycle each of R-CHOP and R-DA-EPOCH regimens, the patient underwent infusion of CD19/CD22 BS LoopCAR-T cells at a dose of 1.73× 108 cells. She experienced a rapid response, developing grade 1 cytokine release syndrome (CRS) and no immune effector cell-associated HLH-like syndrome (IEC-HS), and achieved disease stabilization following aggressive treatment. Bone marrow and peripheral blood flow cytometry at one and three months post-CAR-T therapy showed complete remission (CR). PET-CT at three months post-CAR-T therapy also indicated CR. The patient was followed up until April 2025, and the disease-free survival time after CAR-T treatment exceeded 16 months.Conclusion: The novel CD19/CD22 BS LoopCAR-T therapy is safe and effective in treating high-risk DLBCL patients presenting with HLH.Keywords: hemophagocytic lymphohistiocytosis, diffuse large B-cell lymphoma, CD19/CD22 dual target, chimeric antigen receptor T cells |
